Description
Technical field
The utility model relates to a kind of bellows clamp sleeve, particularly relates to the self-sealed mechanical compaction sleeve of a kind of bellows.
Background technique
Due to the characteristic that the bellows adopting stainless steel material to make can bend, and have the advantage of metal pipe concurrently, be extremely suitable for using in combustion gas from the beginning, water and wet goods pipeline.Can be tightly connected with the hard pipeline of steel or PVC material to make bellows, adopts not flat to connect (mechanical sleeve) and flat in the market and connect (screw thread locknut), but above-mentioned connecting structure is at installation and functionally existing defects:
1. when adopting not flat connection:
Corrugated stainless steel tubing is after cutting off, sharp burrs or fast mouth situation may be there is in the seal face of bellows, during installation, the sealed port of bellows embeds in rubber gasket, but the burr of the seal face of bellows or fast mouth may cut rubber gasket because embedding excessively.Once cut rubber gasket, then can cause seal leakage, produce gas seal and sternly do not cause gas leakage and eliminate sealing effect.During installation, operator not easily grasps operating method and has certain operation easier.Simultaneously, the seal face that corrugated stainless steel tubing is sharp embeds the breakage caused to rubber gasket, also rubber gasket working life can directly be affected, and also easily cause when applying excessive helical pressure to seal face or repeatedly compressing the seal face of bellows excessively to cut Sealing, cause Sealing to damage and affect the sealing effect of bellows.
2. when adopting flat to connect:
Corrugated stainless steel tubing is after cutting off, the body of bellows is blocked again with flat mouth device, hand hammer is used to knock the seal face of bellows to manufacture the sealed end head plane of bellows, the sealed end head plane of bellows and rubber gasket plane contact during connection also carry out screw-threaded coupling by nut, do not damage rubber gasket, thus ensure the sealing effect to gas.This kind of method, the assistant tool of needs is many, the engineering time long, instrument cost is high and complex operation step.
Further, because when installing, bellows and nut exist unidirectional assembling, operator can not easily locate, and if there is location error, need excise redundance, and effect and efficiency are installed in impact thus.
Owing to there is above-mentioned defect in prior art, the installation efficiency of a kind of operator of raising of market in urgent need also reduces the seal leakage situation caused the damage of Sealing and to occur and safer, effectively and do not damage the mechanical compaction sleeve of plastic protective sleeve outside bellows.
Summary of the invention
