Abstract

The invention provides an anti-explosion valve which comprises a valve body, a valve rod, a valve deck and a wheel disc. The wheel disc comprises a wheel disc body. The wheel disc body and the valve rod are fixedly connected together through a fastening bolt. The valve body is provided with an anti-explosion thermal insulation device. The anti-explosion thermal insulation device comprises a loop on the outer layer of the valve body and an air pump control device. The loop and the outer layer of the valve body are firmly connected together through sealing fluid. A locking device is arranged inside the air pump control device. The locking device and the wheel disc are connected together. By the adoption of the technical scheme, the anti-explosion valve is more convenient to use in the industries having the anti-explosion requirement. The anti-explosion valve has the advantages of being simple in structure, convenient to maintain, low in machining cost, high in safety and the like.

Description

Technical field [0001] The invention belongs to a valve, and particularly relates to an explosion-proof valve. Background technique [0002] In the existing technology, a valve is a control component in a fluid conveying system, which has functions such as cut-off, regulation, diversion, prevention of reverse flow, stabilization, diversion, or overflow and pressure relief. Valves used in fluid control systems, ranging from the simplest shut-off valves to the various valves used in extremely complex automatic control systems, have a wide variety and specifications. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. In some special industries, the valve requires a certain safety factor and has an explosion-proof effect. Such a valve is lacking in the market. Summary of the invention [0003] The purpose of the present invention is to provide an explosion-proof valve wit...
