Anti-jammed and anti-blocking wearproof ball valve

Abstract

The invention discloses an anti-jammed and anti-blocking wearproof ball valve which comprises a valve body, a valve element, a valve seat and a valve rod, wherein the valve body comprises a valve main body and a valve body side cover; the valve main body and the valve body side cover can be detached and assembled in a left-right manner; a medium inlet cavity (A), a valve cavity (B) and a medium outlet cavity (C) communicated with each other are arranged in the valve body; the medium inlet cavity (A) is arranged in the valve body side cover; the valve element is of U-shaped non-integral spherical structure composed of an integral valve ball with part of the side wall cut off; a side ball panel is in seal fit with the valve seat when the valve element is in a closed state; the central axis of the valve rod is eccentrically arranged relative to the spherical center of the side ball panel of the valve element, so that the maximum medium circulating clearance exists between the side ball panel and the valve seat when the valve element is in the full open state. The anti-jammed and anti-blocking wearproof ball valve has the advantage that the problems that the middle cavity of the valve is deposited and blocked and the switch of the valve is blocked can be solved during application of a solid particle medium, a solid-containing liquid medium, a solid-containing gas medium and a multiphase complex medium.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an anti-blocking, anti-blocking and wear-resistant valve. Background technique [0002] Valves are used in the conduction and cut-off of various devices such as petroleum, chemical industry, electric power, steel, natural gas, coal chemical industry, polysilicon, etc., especially for valves in devices with a large number of solid particles and multi-phase complex media, which are very easy to jam , blockage, or even unable to switch and move. [0003] A large number of gate valves and ball valves have been used in these devices. Because the cavity of the gate valve is more likely to accumulate materials, the linearly moving gates often cannot be closed downwards, and are more likely to be strained and damaged. In recent years, the proportion of ball valves used is increasing. More, because the ball valve is a 90° angle switch, and the ball and the seat can be hardened with the cu...
