Full-coating sweeping anti-lock abrasion resisting ball valve

Abstract

The invention discloses a full-coating sweeping anti-lock abrasion resisting ball valve, and relates to the technical field of ball valve cleaning. The full-coating sweeping anti-lock abrasion resisting ball valve comprises a ball valve component, an executer, a receiving disc and two adapter flanges. A switch ball is arranged in a containing cavity and connected with a valve rod. The valve rod stretches out of the containing cavity and is connected with the executer. The executer is connected with the receiving disc. The receiving disc is arranged on a valve body and connected with the valve body through a mortise assembly. Two sweeping holes communicate with the containing cavity. Compared with ball valves in the prior art, according to the provided full-coating sweeping anti-lock abrasion resisting ball valve, due to the adoption of the mortise assembly connected between the receiving disc and the valve body and the valve body communicating with the adapter flanges through the sweeping holes, the situation that in the frequent valve rod opening and closing process, components are shaken loosely can be avoided; and deposited materials in the containing cavity can be cleaned, the switch ball is prevented from being locked, practicability is high, and cost performance is high.

Description

technical field [0001] The invention relates to the technical field of ball valve cleaning, in particular to a full-coated anti-lock wear-resistant ball valve with purging. Background technique [0002] Ball valve generally refers to the valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid adjustment and control. In the traditional ball valve design, it is generally divided into two structures: floating ball and fixed ball. According to the particularity of valve classification, under the same sealing requirements, floating ball valve design is usually adopted. Floating ball valve has the advantages of simple sealing structure, small number of parts and relatively cheap manufacturing cost. [0003] In the production process of chemical industry, coal mine, petroleum drilling and other industries, the ball valve has the characteristics of large pressure difference and good cut-off...

AI Technical Summary

Problems solved by technology

The inventor found that with the development of the industry, the improvement of the process, the transportation of high pressure, high flow rate, spray rock cutting slurry, and metal ball particle medium, it is more and more difficult to meet the development needs of existing production by using ordinary ball valves. , mainly reflected in the erosion of the sealing surface and the flow channel, the internal cavity medium interception causes the valve ball to lock and cannot move, which leads to the failure of the ball valve, affects the cutting efficiency, and increases the maintenance cost. Therefore, it is urgent to make necessary improvements to the overall structure of the ball valve
