The invention discloses a kind of socket attachment means of gas appliance connection stainless steel corrugated flexible hose, including flexible pipe, the straight length that the flexible pipe includes bellows segment, is connected as a single entity positioned at bellows segment end and with it, bellows segment outer surface is coated with plastic sheath, the outer surface of straight length is coated with pyrocondensation insulation sleeve, outer on pyrocondensation insulation sleeve to be cased with tight loop, the port of tight loop is provided with the conical surface, provided with the horn mouth with cone match at the external port of straight length and pyrocondensation insulation sleeve；It is bolted with tight loop in nut, nut provided with the rubber sleeve that two sides are male cone (strobilus masculinus), the male cone (strobilus masculinus) of side and the inner conical surface being located in nut match, and male cone (strobilus masculinus) and the horn mouth of opposite side coordinate.With advantages below：Due to the outer pyrocondensation insulation sleeve and metallic sheath for being cased with good insulation preformance on straight tube, it even if electric arc punctures straight tube, can not also puncture pyrocondensation insulation sleeve, the harm of electrical breakdown generation fundamentally be solved, while also not interfering with the intensity of spigot.
Description
Technical field
The present invention relates to a kind of connecting interface of the mechanical novel tube of materiel machining, particularly a kind of gas appliance connection is used
The socket attachment means of stainless steel corrugated flexible hose.
Background technology
Stainless steel corrugated flexible hose is applied to the gas kitchen ranges and other gas appliances being fixedly mounted, because stainless steel ripple is soft
Pipe is with very high body intensity, flow is big, and corrosion-resistant, service life is long, non-aging, mouse bite preventing, in recent years at home
Gas industry is widelyd popularize and used.
From the point of view of the interface of connection, domestic overwhelming majority gas kitchen ranges or traditional socket connected mode.Such a connection
Mode, especially nonstandard in hose coupling, in the case that appearance and size is too small, easily leakage even comes off joint；In addition, in room
Carelessness when when room being fitted up due to horizontal problem or the installation of water power work, zero line and ground wire are linked together, or by ground wire
As zero line, cause ground wire grounded effect bad, cause ground wire electrification, and hose coupling and the corrugated flexible hose port of socket connection
There can be certain gap between the metal inner surface of connecting portion, will picture when there is certain voltage and suitable gap
Electric arc welding equally produces electric arc, can be by ripple when the energy of electric arc reaches certain intensity, or after multiple striking
The metal inner surface of flexible pipe port connecting portion punctures, so as to produce gas leakage, threatens people's life and the safety of property.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of socket of gas appliance connection stainless steel corrugated flexible hose
Attachment means, can either solve the problem of hose coupling is less than normal, and the problem of fundamentally solve electrical breakdown.
In order to solve the above technical problems, the socket connection for the gas appliance connection stainless steel corrugated flexible hose that the present invention is provided
Device, it includes flexible pipe, and the straight length that the flexible pipe includes bellows segment, is connected as a single entity positioned at bellows segment end and with it is described
Bellows segment outer surface is coated with plastic sheath, and the outer surface of straight length is coated with pyrocondensation insulation sleeve, the plastic sheath and pyrocondensation
The outer surface of insulation sleeve is socketed with metallic sheath, and metallic sheath is compressed with plastic sheath and pyrocondensation insulation sleeve respectively；On the metallic sheath
Outer to be cased with tight loop, the port of the tight loop is provided with the conical surface, straight length, pyrocondensation insulation sleeve, is provided with the external port of metallic sheath
With the horn mouth of cone match；It is bolted with tight loop provided with the rubber sleeve that two sides are male cone (strobilus masculinus) in nut, nut, side
Male cone (strobilus masculinus) and the inner conical surface being located in nut match, and male cone (strobilus masculinus) and the horn mouth of opposite side coordinate.In use, hose coupling is inserted
Enter onto the socket attachment means of the present invention, nut is fixed, tightens tight loop, rubber sleeve is by crimp, by flexible pipe
Joint is fixed, and reaches sealing effectiveness, because rubber sleeve uses both sides cone structure, the both sides conical surface respectively with horn mouth and nut
Interior inner conical surface offsets, and compression effect is good, there is good contractive effect.Because the outer pyrocondensation for being cased with good insulation preformance is exhausted on straight tube
Edge set, even if electric arc punctures straight tube, can not also puncture pyrocondensation insulation sleeve, fundamentally solve the harm of electrical breakdown generation；
Because being additionally arranged metallic sheath, the intensity of spigot is added, even if straight tube is breakdown, overall sealing is not interfered with yet and strong
Degree is required.
Preferably, the connection screw thread of the tight loop and nut is closely-pitched metric thread.
Preferably, the bell-mouthed angle is 30 °~60 °
After above structure, gas appliance of the invention connects the socket attachment means of use stainless steel corrugated flexible hose with showing
There is technology to compare, with advantages below：Go for various sizes of hose coupling, rubber sleeve is adjusted by tightening tight loop
Deflection and ensure the reliable sealing of junction, it is therefore prevented that the leakage of combustion gas, be cased with insulating properties additionally, due to outer on straight tube
Pyrocondensation insulation sleeve and metallic sheath that can be good, even if electric arc punctures straight tube, can not also puncture pyrocondensation insulation sleeve, fundamentally solve
The harm that electrical breakdown is produced, while also do not interfere with the intensity of spigot.
Brief description of the drawings
Fig. 1 is that structure of the present invention cuts open schematic diagram.
Wherein：1st, bellows segment, 2, straight length, 3, plastic sheath, 4, pyrocondensation insulation sleeve, 5, tight loop, 6, horn mouth, 7,
