When seal ring is rectangle, closely cooperate although can cooperate with annular containing groove,, production and processing inconvenience, therefore, preferably, the section of described seal ring is circular.Circular seal ring is made easily, simultaneously, can save material, reduces cost.
As preferably, the end face of described annular containing groove both sides cell wall has the ridge that is higher than the bayonet end outer wall.This ridge can contact with the pvc pipe material, also can have very little gap, seal ring is limited within the inwall and annular containing groove of pvc pipe material, avoids seal ring to break away from annular containing groove.
When inserting the pvc pipe material for the bayonet end that makes joint body, reduce and the pvc pipe material between surface friction drag, simultaneously, consider the saving material, preferably, the end face of described ridge is arcuation.
As preferably, the middle part of described joint body is provided with the annular stop bar around circumferential distribution.
After the bayonet end of described joint body inserted the pvc pipe material, the port of described pvc pipe material can conveniently be controlled the degree of depth in the joint body insertion pvc pipe material against described annular stop bar.
A kind of pvc pipe road of liquid-leakage preventing comprises the pvc pipe material, and at least one end of described pvc pipe material is plugged with described pvc pipe material joint.The pvc pipe road has good sealability, can avoid leakage, can be used for the field of high-pressure delivery liquid.
For the sealing that realizes that the pvc pipe road is good, prevent in the leakage of pvc pipe material joint area, preferably, the annular stop bar on the described pvc pipe material of position, the termination butt joint of described pvc pipe material.
If no special instructions, described pvc pipe material is soft pvc tubing in the utility model.
The pvc pipe material joint of the utility model preventing water leakage, can guarantee the sealing that the pvc pipe material connects, even the pvc pipe material is because the cold flow effect produces deformation, seal ring in the joint body annular containing groove also can utilize self elastically-deformable answer to compensate, easy to use, the while good sealing effect.
The pvc pipe material joint that the utility model provides can guarantee at 300kg/cm
2Pressure under used 200kg/cm 10 months
2Use under the pressure 16 months can leakage, general washing machine plumber is 80 ~ 110kg/cm as pressure
