Description
Technical field
This utility model relates to a kind of corrugated tube, particularly relates to a kind of mechanical compaction formula corrugated stainless steel tubing for gas pipeline.
Background technology
Use the most universal as the fuel source in people's daily life of combustion gas, frequently with rubber tube or hard metal tubing as the connecting tube of combustion gas main line Yu gas kitchen ranges in prior art, combustion gas is carried.The two ends galvanized wire at rubber tube is needed to tighten with slip-off preventing by the way of rubber tube links, there is many defects in this connected mode: installs and exchange inconvenience, easy some retardation under bending state, rubber tube corrosion-resistant, the most aging, service life is short, is susceptible to leakage phenomenon；Connected by hard metal tubing and have higher positioning requirements between gas kitchen ranges position and interface pipe installation site to kitchen range, there is following defect in this connected mode: installs and exchange inconvenience, cannot be carried out curved after mounting, then be susceptible to leakage phenomenon due to abrasion when installing.Just because of this, the explosive incident such as the annual carbon monoxide poisoning that above-mentioned reason all can be occurred to cause in all parts of the country or gas leakage.
For solving the problem of the safe and reliable connection of rubber tube, the metal tube with helical fissure is used to be welded with the thread connecting joint of metal as soft connecting tube (corrugated tube), its two ends；There is certain flexibility can arbitrarily bend without bending, and have the advantage of hard metal tubing concurrently, and threaded convenient and reliable, can thoroughly stop leakage phenomenon, thus the accident potential of poisoning, explosive incident is seldom caused because of gas leakage, practical effect is fine.In order to make corrugated tube can be tightly connected with the hard pipeline of steel or PVC material, use the prefabricated joint of engineering in the market or use the joint of clamp sleeve, but said structure is being installed and functionally existing defects:
1. when the joint that employing engineering is prefabricated:
Owing to being completed by specific attachment structure, therefore, in use, the length of corrugated tube is fixed length.This allows for it and can only be confined to little occasion and use, 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 bellows does not has coating:
The outside of corrugated tube of the prior art lacks coating, outside the metal part of corrugated tube can be exposed to, affect attractive in appearance, metal part the most also can be made by extraneous medium effect, it to be corroded, corrugated tube self does not the most have flame retardant effect simultaneously, easily causes leakage accident.
Owing to prior art existing above-mentioned defect, the installation effectiveness of a kind of operator of raising of market in urgent need, reliable coupling mechanism force be provided and reduce the sealing leak situation that the damage to sealing member causes and occur and safer, effectively and there is the corrugated stainless steel tubing of outside coating.
