AI Technical Summary

Technical Problem

The existing eccentric hemispheric valve has uneven force, which can easily lead to local excessive force on the valve seat. The cleaning process requires manual intervention and is not thorough, posing a risk of blockage.

Method used

A lifting ring ball valve is designed, which adopts a centrally symmetrical annular valve core body and a spherical crown-shaped sealing surface, combined with a self-cleaning mechanism and a double sealing structure to achieve uniform force and automatic cleaning, and reduce the risk of clogging.

Benefits of technology

It achieves balanced force on the ball valve, reduces the overall mass, ensures stable sealing, reduces maintenance frequency and cost, and is suitable for fluid control under complex working conditions.

Abstract

The invention relates to a hanging ring type ball valve, and relates to the technical field of spherical crown type sealing surfaces, the hanging ring type ball valve comprises a ball valve body, a handle, a rotating shaft and a valve core, the handle is arranged on the ball valve body, the rotating shaft is arranged on the handle, and the valve core comprises an annular valve core main body integrally forming a spherical surface; spherical crown type sealing faces are arranged on the left side and the right side of the annular valve element body, the diameter of each spherical crown type sealing face is larger than the width of the annular valve element body, other areas, relative to the spherical crown type sealing faces, of the annular valve element body form a valve element flow channel, and the whole annular valve element body is of a central symmetry structure. By means of the valve element structure, the internal stress of the valve seat is balanced, the overall product quality can be reduced, and stable sealing can be achieved on the sealing face.
