Stanje tehnikeThe state of the art

Poznati bešumni ventil sa usmerenim protokom fluida istih prijavioca, a po osnovnoj prijavi P-1439/86 sastoji se od kučišta vretena na čiji je unutrašnji cilindrični deo postavljeno vreteno koje je sa spoljne strane kučišta osigurano osiguračem od aksijalnog pomeranja. Na zavojnicu vretena navrnut je nosač klipa koji u odnosu na kučište vretena zaptiva preko zaptivki izradenih od gume a koji su postavljeni u odgovarajuče žlebove nosača klipa. Na donjem delu nosača klipa, oko vretena , postavljene su dve polutke osigurača koje sprečavaju dalje odvrtanje vretena.The known silent valve with directional fluid flow of the same applicants, and according to the basic application P-1439/86 consists of a spindle housing on which an inner cylindrical part is fitted with a spindle secured on the outside of the housing by an axial displacement fuse. A piston carrier is screwed onto the spindle coil, which, in relation to the spindle housing, seals over gaskets made of rubber, which are mounted in the corresponding grooves of the piston carrier. On the lower part of the piston carrier, around the spindle, there are two fuse arms that prevent the spindle from turning further.

Kod navedenog poznatog bešumnog ventila, u kučištu vretena, izvedeni su na unutrašnjem prečniku zubci koji su u zahvatu sa elastičnim ispustima, izračenim izjedna na nosaču klipa. Kod zatvaranja ventila, okretanjem vretena u smeru kazal jke na satu, pri tiskuje se klip na gumenu zaptivku odredenom šilom, sve dok vreteno ne bude uvrnuto u potpunosti u nosač klipa, kada nastaje povečani otpor, tako da se vreteno zajedno sa nosačem klipa okreče, pri čemu elastični ispusti, savijajuči se elastično, skakuču po zubcima, dok kandže klizaju zakačene po rubu klipa. Ako se sada ovakav ventil duže vremena ne koristi, ili ako je temperaturna razlika relativno velika, povremeno dolazi do blokiranja vretena, kada se želi otvoriti ventil. Ovo je jedan od nedostataka poznatog bešumnog ventila koji se javlja povremeno.In the above known silent valve, in the housing of the spindle, on the inner diameter, the teeth are engaged with elastic discharges, calculated at once on the piston carrier. When closing the valve by turning the spindle clockwise, the piston is pressed onto the rubber gasket by a certain point until the spindle is fully screwed into the piston carrier when increased resistance is formed, so that the spindle rotates with the piston carrier. whereby elastic discharges, bending elastically, leap on the teeth, while the claws slide hooked along the edge of the piston. If the valve is not used for a long time now, or if the temperature difference is relatively large, the spindle will occasionally block when the valve is opened. This is one of the drawbacks of the famous silent valve that occurs occasionally.

Takode kod otvaranja ventila, dolazi do oslanjanja zavojnice na polutke osigurača, pri čemu isti trpe naprezanje i teže da se odupru o zidove kučišta vretena, pri čemu takode rede može da dode do zaglavl jIvanja vretena u trenutku promene sraera okretanja.Also, when the valve is opened, the coil is reliant on the fuse arms, where they suffer stress and tend to resist against the walls of the spindle housing, and may also cause the spindle to become stuck at the time of changing the rotation direction.

Još jedan nedostatak poznatog navedenog bešumnog ventila ogleda se u torne, što su svi elementi ventila, a posebno vreteno sa zavojnicom i nosač klipa izradeni od istog materijala, te je i ova činjenica donekle doprinosila povremenom blokiranju vretena.Another disadvantage of the said silent valve is that of the towers, which are all elements of the valve, especially the coil spindle and the piston carrier made of the same material, and this fact also contributed to the occasional blockage of the spindle.

Opis rešenja tehničkog problemaDescription of solution to a technical problem

Tehnički problem rešen je pronalaskom na taj način, što je na vrat vretena sa zavojnicom, izvedenora na svom početku i kraju sa dijametralno suprotnim zavojnim zubcima, navučen radijalno rasečeni osigurač sa dijametralno suprotno u osnovnoj ploči izvedenim zavojnim zubcima 1 trečira pozicionim zubom, a na zavojnicu vretena navrnut je sa zavojnim zubirna izvedeni kraj unutrašnje zavojnice nosača klipa, pri čemu je na prirubnicu nosača klipa, izvedenu sa dijametralno suprotnim žlebovima i trečim pozicionim žlebom, rubom navučen radijalno rasečeni osigurač.The technical problem is solved by finding a radially dissected fuse with a diametrically opposite flange diametrically opposite the base plate of the winding teeth 1, which treats the positioning tooth on the neck of the spindle with the coil, at its beginning and end with diametrically opposite coil teeth. the spindle is screwed in with a bending tooth end of the inner coil of the piston carrier, whereby a radially dissected fuse is drawn to the flange of the piston carrier, made with diametrically opposite grooves and a third position groove.

Pronalazak če biti bliže objašnjen na osnovu primera izvodenja prikazanog na crtežima, pri čemu:The invention will be explained in greater detail by way of an exemplary embodiment shown in the drawings, wherein:

sl. 1 prikazuje vreteno sa zavojnicom i zavojnim zubirna, sl. 2 prikazuje presek A-A sa sl. 1, sl. 3 prikazuje pogled odozgo na vreteno, sl. 4 prikaz-uje nosač klipa u preseku, prema A-A sa sl. 6 sl. 5 prikazuje pogled odozdo na nosač klipa sa sl. 4, sl. 6 prikazuje pogled odozgo na nosač klipa, sl. 7 prikazuje presek radijalno rasečenog osiflurača sa sl. 8 po liniji A-A i sl. 8 prikazuje pogled odozgo na radijalno rasečeni osigurač.FIG. 1 shows a spindle with a coil and a bending gear, FIG. 2 shows a cross-section A-A of FIG. 1, FIG. 3 shows a top view of the spindle; FIG. 4 is a cross-sectional view of the piston carrier according to A-A of FIG. 6 fig. 5 shows a bottom view of the piston carrier of FIG. 4, FIG. 6 shows a top view of the piston carrier, FIG. 7 shows a cross-section of a radially dissected oscillator of FIG. 8 along line A-A and the like. 8 shows a top view of a radially dissected fuse.

Na sl. 1,21 3 prikazano je vreteno 10 bešumnog ventila, prema osnovnoj prijavi P-1439/86 a koje se razlikuje po torne, što je na početku 1 na kraju zavojnice 8 Izvedeno sa zavojnim zubcima 31, 32 koji su u paru dijametralno suprotno rasporedeni, a medusobno zakrenuti za 90°.In FIG. 1,21 3 shows the silent valve spindle 10, according to basic application P-1439/86, which differs by friction, which is at the beginning 1 at the end of the coil 8 Made with coiled teeth 31, 32 which are in diametrically opposite pairs. and rotate each other by 90 °.

Na sl. 4, 5 i 6 prikazan je nosač 7 klipa bešumnog ventila koji ima unutrašnju zavojnicu 8‘. ZavrŠetak, tj. kraj unutrašnje zavojnice 3' ima naspramne zubce 37 izvedene zavojno, na koje se čeono oslanjaju zavojni zubci 31 zavojnice 8 vretena 10, nakon njegovog uvrtanja u nosač 7 klipa, čeonim oslanianjem zavojnih zubaca 31 i 37 sa sigurnošču je izbegnuto blokiranje vretena 10_s jer je specifični pritisak u ovom slučaju največi.In FIG. 4, 5 and 6, a silent valve piston carrier 7 having an inner coil 8 'is shown. Completion, ie. the end of the inner coil 3 'has opposing teeth 37 made coiled, on which the coil teeth 31 of the coil 8 of the spindle 10 rely, after its screwing into the piston carrier 7, and the locking of the coiling teeth 31 and 37 with safety prevents the locking of the spindle 10 _s because the specific pressure in this case is greatest.

Na prirubnici 38 nosača 7 klipa, dijametralno suprotno izvedeni su žlebovi 39 a u odnosu na njih pod 45° treči pozicioni žleb 40 koji sadejstvuju tj. u koje zaleze zubci 35 i pozicioni zubac 36 rasečenog osigurača 20, prikazanog na sl. 7 i 8.On the flange 38 of the carrier 7 of the piston, grooves 39 are diametrically opposite, and in relation to them at 45 °, the third position groove 40 which cooperates, ie. into which the teeth 35 and the position tooth 36 of the cut-off fuse 20 shown in FIG. 7 and 8.

Na sl. 7 i 8 prikazani rasečeni osigurač 20 sastoji se od osnovne ploče 33 na kojoj su polukružno, u vidu strme ravni izvedeni zavojni zubci 34 koji sadejstvuju, tj. oslanjaju se u otvorenom stanu ventila na zavojne zubce 32 vretena 10. Na osnovnoj ploči 33 osigurača 20 izvedeni su naspramno i pravi zubci 35 i pod 45° treči pozicioni zubac 36. Osigurač 20 ima rub 41 koji se navlači na prirubnicu 38 nosača 7 klipa, pri montaži osigurača 20. Pozicioni žleb 40 na nosaču 7 klipa kao i zubac 36 služi samo za to, da se osigurač 20 uvek montira u istom odredenom položaju.In FIG. 7 and 8, the cut-off fuse 20 shown consists of a base plate 33 on which, in the form of a steep, steeply-wound, coil-shaped teeth 34, i.e. in the open housing of the valve rely on the coil teeth 32 of the spindle 10. On the base plate 33 of the fuse 20, opposite and straight teeth 35 and at 45 °, a third positional tooth 36 is formed. The fuse 20 has an edge 41 which is threaded onto the flange 38 of the carrier 7 of the piston. when mounting the fuse 20. The position groove 40 on the piston carrier 7 as well as the tooth 36 serves only to ensure that the fuse 20 is always mounted in the same predetermined position.

Način funkcionisanja sklopa vretena, rasečenog osigurača i nosača klipa koji su predmet ovog pronalaska je sledeči:The way the spindle, fuse, and piston assembly assemblies that are the subject of the present invention function is as follows:

Nakon navlačenja, blagim deformisanjem osigurača 20 na vrat 30 vretena 19 bešumnog ventila, navrtanjem nosača 7 klipa na zavojnicu 8 vretena 10 i navlačenjem ruba 41 nosača 20 na prirubnicu 18 nosača klipa, dobijeni sklop se kompletira sa ostalim delovima koji nisu ovde prikazani i postave u kučište bešumnog ventila koje takode ovde nije prikazano.After retracting, by slightly deforming the retainer 20 on the neck 30 of the valve 19 of the silent valve, by screwing the piston carrier 7 onto the coil 8 of the spindle 10 and by pulling the edge 41 of the carrier 20 onto the flange 18 of the piston carrier, the resulting assembly is completed with other parts not shown here and fitted silent valve housing not also shown here.

Zakretanjem vretena 10 u smeru kazaljke na satu u cilju zatvaranja ventila, posle nekoliko obrtaja zavojni zubci 31 vretena 10 svojim čeonim delom osi one se na zavojne zubce 37 izvedene naspramno na završetku zavojnice 8' nosača 7 klipa. 0v1m čeonim oslanjanjem izbegnuto je da se i čelo vretena 10 osloni na dno zavojnice 8‘ kao i sva druga naprezanja koja bi izazvala blokiranje zavojnice 8 u unutrašnjoj zavojnici 8'.By rotating the spindle 10 clockwise to close the valve, after a few turns, the coiling teeth 31 of the spindle 10 axially pivot onto the coiled teeth 37 opposite to the end of the coil 8 'of the piston carrier 7. The 0v1m front suspension prevents the spindle head 10 from resting on the bottom of the coil 8 'as well as any other stresses that would cause the coil 8 to lock in the inner coil 8'.

Odvrtanjem vretena 10 suprotno kazaljci na satu, zavojni zubci 32 čeono se oslanjaju na zavojne zube 34 osigurača 20, čime je takode onemogočeno olokiranje vretena 10, odn. njegove zavojnice 8.By turning the spindle 10 anticlockwise, the coiling teeth 32 are reliably supported by the coiling teeth 34 of the fuse 20, which also prevents the spindle 10 from being locked or dislodged. its coils 8.

I u slučaju otvaranja i zatvaranja, obezbedeno je ooznato preskakovanje kandži propračeno zvukom, što je ujedno i signal da je ventil dovoljno zatvoren ili otvoren.In the case of opening and closing, there is a known skipping of the claws accompanied by sound, which is also a signal that the valve is sufficiently closed or opened.

Navod o najboljem načinu za privrednu upotrebu prijavljenog pronalaskaA statement of the best way to commercially use the claimed invention

Za posti zanje osnovnog cilja - da se pri otvaranju ili zatvaranju ventila izbegne blokada zavojnice vretena - raože se reči da, za privrednu upotrebu predmetnog pronalaska, nisu potrebna neka posebna znanja, iskustva i uputstva koja bi trebalo primeniti. Potrebna su 1 dovoljna samo ona znanja koja poseduje prosečan stručnjak, a koristeči dati opis pronalaska.In order to achieve the basic objective of avoiding blockage of the spindle coil when opening or closing the valve, it is said that, for the commercial use of the present invention, no specific knowledge, experience and instructions need to be applied. Only 1 knowledge of the average person skilled in the art is needed, using the description given.

Pored rečenog, ipak je potrebno obrati ti pažnju i na sledeče:In addition, you also need to pay attention to the following:

a) vreteno 10 izradeno je od poliamida ojačanog staklenlm vlakniraa i liveno u kalupu brizganjem,a) spindle 10 is made of glass fiber reinforced polyamide and molded by injection molding,

b) pozicioni zub 36, odn. žleb 40 može da bude pod proizvoljnim uglom, konkretno ovde je pod 45° a služi da bi se osigurač 20 raontirao uvek u istom položaju.b) positional tooth 36, or. the groove 40 may be at an arbitrary angle, in particular here it is below 45 °, and serves to keep fuse 20 always in the same position.
