Compared with prior art, the utility model has the advantages that：
1. the delivery valve structure of the utility model passes through the Shockproof gasket of steel ball and flowline junction, it is possible to reduce steel
Abrasion between ball and flowline is conducive to the service life for improving steel ball, avoids because of worn steel ball larger impact delivery valve
Using effect.
2. the delivery valve structure of the utility model can be with delivery valve by the gasket and pressed seat at the top of delivery valve holder
Tight seat connect with valve body it is even closer, avoid delivery valve using when there is obscission, and pass through valve body and delivery valve holder
The sealing rubber ring of junction is conducive to the leakproofness for improving delivery valve.
3. the delivery valve structure of the utility model can be to delivery valve by the damping chamber and damping device of body base
The vibrations of generation avoid delivery valve from being loosened for a long time using rear inner body into row buffering and damping, are conducive to improve delivery valve
Stability and service life.
