Eccentric semi-ball valve capable of reducing abrasion of valve seat

Abstract

The invention discloses an eccentric semi-ball valve capable of reducing abrasion of a valve seat. The eccentric semi-ball valve comprises a valve body and a ball body, wherein the ball body is arranged in the valve body, a top cover is arranged at the top end of the valve body, the bottom end of the top cover is connected with the top end of the ball body, a control head is fixed to the middle position of the top end of the top cover, the two ends and the two sides of the top of the valve body are each provided with a dismounting structure, each dismounting structure comprises a groove, a protruding block, a screw and a threaded groove, the grooves are formed in the two ends and the two sides of the top of the valve body respectively, and the protruding blocks are inserted into the grooves. When the valve body is damaged, a worker only needs to rotate the screws through threaded connection between the screws and the threaded grooves, i.e., the screws can be screwed out of the grooves and the protruding blocks, at the moment, force is applied to the top cover to separate clamping between the grooves and the protruding blocks, and then the top cover can be detached; and at the moment, the worker can carry out troubleshooting work on the interior of the valve body, so that the convenience is improved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an eccentric hemispherical valve capable of reducing valve seat wear. Background technique [0002] With the continuous development of society and the continuous improvement of scientific level, valves are now required in urban drainage, chemical industry, etc. Valves can be used to block some media, among which ball valves are one of the important components of valves, and eccentric semi- Ball valves are widely used because of their advantages. Traditional eccentric hemispherical valves often wear too much after being used for a long time, resulting in reduced service life. Therefore, it is necessary to use an eccentric valve that can reduce seat wear. Half ball valve. [0003] There are many types of eccentric hemispherical valves on the market today, which can basically meet people's needs, but there are still some problems: when using traditional eccentric hemispherical valve...
