When reduction high-pressure rubber pipe is pressurizeed or depressurized suddenly due to part in use, the probability of high-pressure rubber pipe explosion is caused,
The security performance and sealing property when high-pressure rubber pipe is used are improved, the resource such as hydraulic pressure or air pressure is effectively saved.
The technical solution adopted in the present invention is：A kind of pipe joint pre-compressing device, is connected to pipeline to be connected and is connect with pipe
Wherein one end of the connecting portion of head, pre-compressing device includes the housing being enclosed on outside pipeline to be connected, and housing is close to pipe joint
One end is additionally provided with plug division；Housing is circumferentially additionally provided with some pretension chambers, and each pretension intracavitary is distinguished successively from outside to inside
Adjustment structure and stage clip are connected with, compression ring is additionally provided between pretension chamber and pipeline to be connected.The present invention is using in pipe joint
Increase single pre-compressing device close to one end with connecting pipe, realize the pre-pressing force for treating connecting pipe, when pipeline by
When being pressed to abruptly increase or the pipe die-offed, it can be eased by the stage clip and compression ring that are connected thereto, that is, institute's stage clip
Absorption tube pressure and fully separator tube pressure are played with compression ring, the probability of pipeline burst is reduced, improves its security performance, effectively
Hydraulic pressure or air pressure resource are saved in ground.
Preferably, several circumferential arrays of pretension chamber along housing, to play uniform cushioning effect.
Preferably, the quantity of pretension chamber is no less than three, so as to play preferable pre-pressing effect.
Preferably, bushing is also associated with inside the one end of housing away from pipe joint, improves the anti-wear performance of pre-tightening apparatus.
Preferably, compression ring is rubber ring or compressed sponge circle, to ensure that there is compression ring to have good stretch for it
Performance.
Preferably, adjustment structure is bolt or screw or screwed handle, to adjust the pre- of pre-tightening apparatus
Clamp force.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is using close with connecting pipe in pipe joint
One end increases single pre-compressing device, realize the pre-pressing force for treating connecting pipe, when pipeline is by abruptly increase or die-offs
When pipe is pressed, it can be eased by the stage clip and compression ring that are connected thereto, that is, institute's stage clip and compression ring play absorption
Pipe pressure and fully separator tube pressure, reduce the probability of pipeline burst, improve its security performance, effectively saved hydraulic pressure or
Air pressure resource.
When pressurizeing or depressurize suddenly due to part in use present invention reduces high-pressure rubber pipe, high-pressure glue is caused
The probability of pipe explosion；The security performance and sealing property when high-pressure rubber pipe is used are improved, hydraulic pressure or gas has effectively been saved
The resources such as pressure.
