Problems solved by technology

In the actual working process, this structure is difficult to maintain the tightness of the valve core for a long time. With the extension of the use time, the impact force of the valve core is very large under the impact of the external force of the fluid, and the sealing ring is easy to loosen or even fall off. Affect the sealing effect of the sealing ring on the valve core

Abstract

The invention provides a water valve valve core sealing ring manufacturing mold applied in the technical field of water valve valve core sealing ring, the invention also relates to the assembly method of the sealing ring, the bottom cover of the water valve valve core sealing ring casting mold A plurality of limiting sand tires (2) are arranged on the plate (1), and the limiting sand tires (2) form an annular limiting part (3), and a gap is arranged between every two adjacent limiting sand tires (2) part (4), the limiting part (3) outer ring sets the limiting outer ring (5), the inner ring of the limiting part (3) is provided with a positioning cylinder core (6), the positioning cylinder core (6) and the limiting part (3 ) to form a casting cavity (7), the water valve core sealing ring casting mold of the present invention has a simple structure, can process the sealing ring conveniently and quickly, effectively improves the sealing performance between the sealing ring and the valve core, and ensures that the sealing ring Long-term use without falling off, improving the reliability and service life of the sealing ring.

Description

technical field [0001] The invention belongs to the technical field of water valve valve core sealing ring, more specifically, relates to a manufacturing mold for water valve valve core sealing ring, and also relates to an assembly method of the sealing ring. Background technique [0002] In the application process of large water valves, the sealing of the water valve is a big problem, and in the working process of the water valve, the quality of the sealing device of the water valve determines the overall working performance and efficiency of the water valve. The large-scale water valve currently used is mainly sealed by a valve core sealing ring (sealing ring, plate ring), that is: by clamping the sealing ring and the valve core to realize the cooperation and fixing of the sealing ring and the valve core. In the actual working process, this structure is difficult to maintain the tightness of the valve core for a long time. With the extension of the use time, the impact for...
