Compared with prior art, the utility model has the beneficial effects that
1, by there are four setting the first convex block, and the inner ring of itself and sealing ring body is coaxially disposed, and the first convex block is uniform
It is provided with the upper surface of sealing ring body, the performance of the multi-layer sealed sealing for being conducive to improve sealing ring.Second convex block is equipped with
Three, and the inner ring of itself and sealing ring body is coaxially disposed, the second convex block is uniformly provided with the lower surface of sealing ring body, multilayer
It is sealed with the performance for being conducive to improve the sealing of sealing ring.Sealing ring body has multi-layer sealed convex block up and down, can effectively improve
The sealing performance of the sealing ring of non-return valve pipeline connection, and then the waterproofness of Mi Quan is improved, prevent drainage.
2, the first convex block it is two neighboring between form the first cavity, form the second cavity between the second convex block is two neighboring,
By the way that the first convex block and the second convex block are staggered, under the elastic reaction of sealing ring body, extruding that the first convex block is subject to
Power is applied to the second cavity, and the extruding force that the second convex block is subject to is applied to the first cavity, and the two is when being squeezed, two kinds of convex blocks
Slight deformation can weaken the abrasion extruding force that sealing ring body is subject to, to improve the service life of sealing ring body, in turn
Improve the waterproofness of sealing ring body.
