Problems solved by technology

[0003] Most of the valves commonly used in the industry are made of metal. When the fluid in the valve contains solid particles with large diameters, the particles in the fluid will wear the metal inner wall of the valve body and shorten the service life of the valve. Therefore, it is necessary to improve the inner wall of the metal valve. Wear resistance to increase the life of metal valves

Abstract

The invention discloses a valve with a ceramic protecting lip. The valve comprises a valve body and a valve core, wherein the valve body comprises a runner; an installing groove with the diameter being greater than that of the runner is formed in the runner along the axis; an annular ceramic protecting lip is arranged in the installing groove; the height of the protecting lip is equal to the width of the installing groove; the outer diameter of the protecting lip is less than the diameter of the installing groove; a heat inlaying material layer is arranged between the outer wall of the protecting lip and the installing groove; the inner diameter of the protecting lip is equal to the diameter of the runner; and the end surface of the protecting lip leans against the valve core when the valve core is in closed state. The invention aims at providing the valve with the ceramic protecting lip so as to improve the wear resistance of the inner wall of the metal valve and further prolong the service life of the metal valve.

Description

technical field [0001] The invention relates to the field of valves, in particular to a valve with a ceramic protective lip. Background technique [0002] Valves are control components in fluid delivery systems. Valves are used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. [0003] Most of the valves commonly used in the industry are made of metal. When the fluid in the valve contains solid particles with large diameters, the particles in the fluid will wear the metal inner wall of the valve body and shorten the service life of the valve. Therefore, it is necessary to improve the inner wall of the metal valve. Wear resistance to increase the life of metal valves. Contents of the invention [0004] The invention intends to provide a valve with a ceramic protective lip to improve the wear resistance of the inner wall of the metal valve and increase the service life of the met...
