Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] refer to Figure 1-4 , a multi-swing type automatic centering and sealing valve clack structure, including a valve clack 2 and a valve clack seat 1, the upper end of the main body of the valve clack 2 is a valve clack head 2-1, and the valve clack head 2-1 is in the shape of a spherical tank body; used for centering connection with valve disc seat 1 and realizing automatic centering of valve disc sealing surface; there is a swing gap adjacent to valve disc 2 and valve disc seat 1, which is used for valve disc head 2-1 to swing and align .

[0017] The swing gap is realized by the pre-tightening force of the spring. The end surface of the disc seat 1 adjacent to the valve disc 2 and the disc seat 1 is evenly distributed with a spring hole 1-1, and a pre-loaded spring hole 1-1 is installed in the spring hole 1-1. Tighten spring 4. Whe...

Abstract

A multi-pendulum type automatic centering valve clack sealing structure comprises a valve clack and a valve clack seat, a valve clack head is arranged at the upper end of a main body of the valve clack, and the valve clack head is a spherical tank body; the valve clack head is used for being connected with the valve clack seat in a centering mode, and a swing gap is reserved between the valve clack and the valve clack seat and used for swing alignment of the valve clack head. According to the multi-pendulum type automatic centering valve clack sealing structure, the problem of inner leakage of the valve clack caused by medium impact force impacting sealing during rapid movement of a valve closing piece is solved, so that the reliable sealing performance of a rapidly-moving valve is achieved.

Description

technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to a multi-swing type automatic centering and sealing valve clack structure. Background technique [0002] With the rapid development of my country's industrialization, various industrial enterprises are increasing day by day, and the pollution to the environment is also increasing. In order to prevent environmental pollution, the amount of valves is greatly increased, but in some harsh working conditions, valve leakage and failure often occur. [0003] The sealing disc is a very critical part of the valve. If it is not closed tightly, it will affect the function of the valve to cut off the medium, that is, the valve has internal leakage. For the cut-off valve, internal leakage is not allowed. Contents of the invention [0004] The invention provides a multi-swing type self-centering valve disc sealing structure, which prevents the valve from being damaged by the impac...
