[0002] At present, there are three main ways to connect small-caliber plastic valves on the market. The first is gluing, that is, the pipe is inserted into the valve joint, and the pipe and valve are connected by gluing; the second is hot melting, the pipe and valve are all made of hot-melt materials, and the pipe and valve are connected by hot melting; the third is threaded connection, that is, the pipe and valve are connected by threads. In actual use, the above three connection methods all have obvious disadvantages. The gluing site needs to apply glue, the hot melting site needs electricity, and the threaded connection site needs to wrap sealing tape. The on-site construction is inconvenient and the construction efficiency is low. Especially when the valve fails and needs to be replaced, both the gluing and hot melting methods require the destruction of the valve and the pipe before the valve can be replaced, resulting in a lot of unnecessary waste.

The trapezoidal boss 42 of the valve joint 4 and the groove 11 of the nut 1 are matched and clamped one by one, so that the connecting pipe can be quickly fixed on the valve, the installation speed is fast, and the disassembly is also convenient, which improves the work efficiency during installation and disassembly, has high practicality, and effectively prevents the connecting pipe from being pulled out. The connection structure is safe and reliable, and the reliability and stability of the seal are improved.

[0030] The first locking groove 6 and the second locking groove 7 can be locked together, and their structure can be a sawtooth structure or a step structure.

[0031] In one embodiment of the present invention, preferably, the elastic collar 3 is provided with elastic barbs 31 for preventing the connecting pipe from being pulled out, and the elastic collar 3 is made of spring steel.

[0032] In this embodiment, by providing elastic barbs 31 on the elastic clamp ring 3, the connecting pipe can be effectively prevented from being pulled out, and the elastic clamp ring 3 is made of spring steel and has excellent comprehensive properties, such as mechanical properties, anti-elasticity, fatigue properties, etc.

[0033] In one embodiment of the present invention, preferably, the contact portion between the trapezoidal boss 42 and the slot 11 is the surface where the hypotenuse of the trapezoidal boss 42 is located, and when rotating clockwise, the inclined surface rises, the nut 1 is tightened and the elastic retaining ring 3 and the sealing gasket 2 are pressed.

[0034] In this embodiment, the contact portion between the trapezoidal boss 42 and its corresponding engaging groove 11 is the surface where the hypotenuse of the trapezoidal boss 42 is located, and the engaging groove 11 contacts the valve connector 4 at the inclined surface. When rotating clockwise, the inclined surface rises, and the nut 1 moves inward and is tightened, pressing the elastic retaining ring 3 and the sealing gasket 2.
