Description
Technical field
This utility model relates to a kind of corrugated tube, particularly relates to a kind of gas appliance connection corrugated stainless steel tubing being suitable for pipelines interface.
Background technology
Gas appliance connection corrugated tube is exclusively used in source of the gas and the flexible connecting lines of stationary gas kitchen range such as connection combustion gas main line, transmission combustion gas, coal gas, oil liquefied gas or biogas, and it is the most universal.Corrugated tube is to use metal charge to make, there is the soft connecting tube of the metal material of helical fissure, corrugated tube has certain flexibility and can arbitrarily bend without bending, and the advantage having hard metal tubing concurrently, the installation of rubber tube will not be produced and exchange inconvenience, will not under bending state easy some retardation, corrosion-resistant will not be produced, the most aging, service life is short and be susceptible to leakage phenomenon.
But the corrugated tube two ends used in prior art all use nipple mode or two ends all to use Green's joint style to connect combustion gas main line and gas kitchen ranges, although it is easy to connect reliably, can thoroughly stop leakage phenomenon, avoid causing the accident potential of poisoning, explosive incident because of gas leakage, but connected mode underaction；Meanwhile, prior art, in order to make corrugated tube can be tightly connected with the hard pipeline of steel or PVC material, uses the prefabricated joint of engineering in the market or uses the joint of clamp sleeve, but said structure is being installed and functionally existing defects:
1. when the joint that employing engineering is prefabricated:
Participating in China Patent No. is " plug-in spiral corrugated metal flexible coupling pipe " of ZL 97225276.2, ZL 97225278.9 " spiral corrugated metal flexible coupling pipe " and " a kind of improved metal soft tube " of ZL 01211062.0 disclose three kinds of processing and there is the structure of soft connecting tube and the scheme of spiral corrugated metal pipe, its two ends are welded with the thread connecting joint of metal；These three relates to scheme and have employed corrugated metal tube body, there is certain flexibility can arbitrarily bend without bending, and it is threaded convenient and reliable, can thoroughly stop gas leakage, choke, the phenomenon such as leak, thus eliminating the accident potential causing poisoning, explosive incident because of gas leakage, practical effect is fine.But due in above-mentioned three kinds of technical schemes, the termination of corrugated flexible metal tube main body all must be welded with a metal joint, its length dimension is just limited by this, once determine and just cannot change dispatching from the factory, more cannot carry out free cutting according to Len req at the scene.And various mounting location of can not being used widely.
2. when using clamp sleeve joint:
See " attachment structure of the corrugated tube of a kind of improvement " that China Patent No. is 200810059270, this attachment structure includes two liners and a nut, the inner side of liner has the shape matched with corrugated tube outer surface, spiro cap is on corrugated tube, nut is connected with adapter by screw thread, and the shade of nut is blocked in the end of above-mentioned liner.
The attachment structure of above-mentioned corrugated tube is to utilize liner to withhold on corrugated tube, makes corrugated tube not fall out；Then utilize nut to block liner, just make corrugated tube and adapter fix after nut is connected with adapter and be connected.Sealing ring set between adapter and corrugated tube can play the effect of sealing, to prevent junction from leakage phenomenon occur.
During owing to installing, the stopping means of corrugated tube exists provides the insecure situation of coupling mechanism force, if operator are excessive force when locking, the stopping means utilizing crest shape single with corrugated tube to coordinate may be damaged, cause position-limit mechanism to fracture or corrugated tube single crest gross distortion, cause providing enough coupling mechanism forces to cause leakage.Need to excise relevant corrugated tube crest to repair the part of damage, thus effect and efficiency are installed in impact.Simultaneously because seal face there may be sharp burrs or fast mouth situation when corrugated tube produces, easily cause corrugated pipe end plane incision sealing member when it is applied excessive helical pressure or repeatedly compresses, cause sealing member to damage and affect the sealing effectiveness of corrugated tube.
3. when the two ends of corrugated tube all use same joint:
The two ends of metal bellows of the prior art all use the joint of identical type, but when combustion gas main line uses different types of joint between the two with gas kitchen ranges, can cause the inconvenience that corrugated tube connects.Such as combustion gas main line uses nipple and gas kitchen ranges uses Green's joint, then cannot directly use metal bellows of the prior art to be attached both.
4. when bellows does not has coating:
The outside of metal bellows of the prior art lacks coating, outside the metal part of corrugated tube can be exposed to, affects attractive in appearance, metal part the most also can be made to be corroded it by extraneous medium effect, can be hurt by extraneous sharp weapon simultaneously, easily cause leakage accident.
Owing to there is above-mentioned defect in prior art, market in urgent need is a kind of is applicable to pipelines interface, have and improve the installation effectiveness of operator, reliable provide coupling mechanism force and reduce the sealing leak situation that the damage to sealing member causes and occur and safer, effectively and have the corrugated stainless steel tubing of outside coating.
