Brief description of the drawings
Fig. 1 is the schematic perspective view of the utility model air bleeding valve.
Embodiment
It please join shown in Fig. 1, the utility model discloses a kind of air bleeding valve 100, and it can be applied to engine exhaust system
In, such as in noise reduction bag.The air bleeding valve 100 include can relative to pedestal it is (not shown) opening or closing valve 1 and
The hydraulic mechanism 2 being engaged with the valve 1.
The valve 1 includes pivot 11 so that it can be rotated around pivot 11.In the implementation of the utility model diagram
In mode, the valve 1 is additionally provided with a pair of adjutages 12.
The hydraulic mechanism 2 includes hydraulic cylinder 21, the piston 22 in the hydraulic cylinder 21, compresses the piston
22 return spring 23 and the connecting rod 24 being connected with the piston 22, wherein the connecting rod 24 is connected with the valve 1
Together, the rotation of the valve 1 can drive the connecting rod 24 to be moved with piston 22 in the hydraulic cylinder 21 simultaneously.
In the utility model embodiment illustrated, the connecting rod 24 is articulated on the valve 1.One end of the connecting rod 24
Positioned at this between adjutage 12 and being articulated in this on adjutage 12.
The hydraulic cylinder 21 is included positioned at the first cavity 211 of the side of piston 22 and another positioned at the piston 22
Second cavity 212 of side.The connecting rod 24 passes through first cavity 211, and the return spring 23 is located at described second
In cavity 212.In the utility model embodiment illustrated, the piston 22 is communicated with first cavity 211 and institute
State the perforation 221 of the second cavity 212.In first cavity 211 and second cavity 212 filled with hydraulic medium (such as
Hydraulic oil).
In addition, the air bleeding valve 100 is provided with to support the hold-down support 3 of the hydraulic cylinder 21.In the utility model
In embodiment illustrated, the hydraulic cylinder 21 is articulated on the hold-down support 3, it is ensured that hydraulic cylinder 21 is certain
It can move and rotate in degree.
When high velocity air is blown along arrow, the stress of valve 1 rotates backward around pivot 11, and now connecting rod 24 is with living
Plug 22 is moved rearwards together in hydraulic cylinder 21；Hydraulic medium in the second cavity 212 enters institute through perforation 221
State in the first cavity 211；Meanwhile return spring 23 is compressed.Hydraulic medium (such as hydraulic oil) has certain stickiness, Neng Gouqi
Cause the speed during pushing quickly, therefore will not will not produce and open and close to certain damping action.When air-flow power and return
When spring force is equal, reach balance, and keep stable state.
When air velocity reduces, return spring power is more than power caused by air-flow, the advance the puck of piston 22, and now hydraulic pressure is situated between
Matter is moved backward by perforation 221；Valve 1 rotates forward, and the damping action of hydraulic medium make it that velocity of rotation is slow.Work as valve
When 1 EDGE CONTACT is to pedestal, stop operating.Now hydraulic mechanism 2 reaches balance, and the damping action of hydraulic pressure causes valve 1
It will not back and forth open and close, reduce vibration, reduce noise.
The utility model realizes the slow of valve in gas extraction system using the damping action of hydraulic pressure and the elastic force effect of spring
The slow function of opening with slowly closing, reduce the construct noise that itself vibration is brought.
In addition, above example is merely to illustrate the utility model and not limits the technical side described by the utility model
Case, understanding of this description should be based on persons of ordinary skill in the field, although this specification is with reference to above-mentioned
Embodiment has been carried out being described in detail to the utility model, still, it will be understood by those within the art that, affiliated skill
Still the utility model can be modified by the technical staff in art field or equivalent substitution, and all do not depart from this practicality newly
The technical scheme of the spirit and scope of type and its improvement, it all should cover in right of the present utility model.
