A high pressure check valve for mud pumps

Abstract

The utility model discloses a kind of high-pressure check valve for mud pump, it is related to mud pump technical field.The check valve includes valve cover, valve body, valve core, spring, locating support rod and the like component;Valve cover is equipped with water V mouth using V-shaped camber structure, can avoid medium flow to produce bubble, prevent cavitation erosion;Valve cover is integrally formed by thread connection with valve body, valve core is equipped with valve core structure seal, in combination with the cooperation of valve cover chamfer and valve core arc surface, realize complete sealing;Valve body is equipped with spring groove, locating hole and movement limit step, respectively guarantee spring stability, valve core accurate movement and stroke limit.The utility model solves the problem that existing check valve is easy to wear under high pressure, poor sealing, realizes long time stable work, improves the volumetric efficiency and reliability of mud pump, applicable to various high-pressure mud pump.
