Abstract
The present invention mainly is that the pipe joint outside has an energy storage cavity, utilize plastic tube or metal liquid in pipe or gas to enter the inwall of compressing self-tightening pipe coupling behind the energy storage cavity, make it to combine closely with pipe or water tap, play the effect that compresses automatically, the big more then effect of pipe internal pressure is good more, is particularly useful for having the pipe connection of highly pressurised liquid or gas.
Description
The present invention is on the basis of common tube joint, increased an energy storage cavity in its outside, after utilizing plastic tube or metal liquid in pipe or gas to enter the energy storage cavity, compressing self-tightening pipe coupling inwall, make it to combine closely with pipe or water tap, can play the self-tightening effect, the big more then effect of pipe internal pressure is good more, is particularly useful for having the pipe connection of highly pressurised liquid or gas.
Before this, various pipe joints utilize mechanical force or bonding masterpiece impacting force also can connect together with pipe or water tap, but are to use inconvenience, and the plastic tube that has does not also have good connecting means at present, and under high pressure using effect is also undesirable.
The key of this product manufacturing is, self-tightening pipe coupling is as figure, and internal diameter φ a matches well about the little 0.1mm～0.2mm of tube outer diameter of usefulness, i.e. interference fit, to keep out because the impact that gate valve throws open.After caliber, liquid in pipe or the gas pressure of pipe were determined, the self-tightening pipe coupling impacting force is main, and to insert this pipe joint length h relevant with metal tube or plastic tube, guarantee definite h under enough impacting force prerequisites.The definite of b value will guarantee that liquid or gas can be charged in the energy storage cavity (1) rapidly, and little (2) are limit daiss, avoids two pipes to the top, causes the energy storage cavity ineffective.
Self-tightening pipe coupling will adopt certain flexible soft plastic manufacturing.
The present invention's product can be used for the connection of the pipe and the water tap of various materials and various calibers, utilize this kind principle, can make the pipe joint, elbow of various series, two logical, threeway, four-way, pipe plug or the like.
The present invention's product are particularly useful for the connection of plastic tube, need not any instruments during use, as long as pipe is inserted self-tightening pipe coupling, for the connection of plastic tube provides a kind of good method with hand.
Claims (4)
1, a kind of self-tightening pipe coupling is characterized in that, an energy storage cavity (1) is arranged on the pipe joint, and two limit daiss (2).
2, pipe joint according to claim 1 is characterized in that the energy storage cavity length of pipe joint is similar to 2h, and energy storage cavity thickness b is 3mm～20mm.
3, pipe joint according to claim 1 is characterized in that internal diameter of pipe joint a is than the little 0.1mm～0.3mm of tube outer diameter that pipe joint connected.
4, pipe joint according to claim 1 is characterized in that the high 2mm～5mm of limit dais.
