Abstract

The invention discloses an explosion-proof two-way valve which includes a valve body, a valve disk shaft, a limit switch mounting plate, a spring, a sealing gland A, a valve disk operation rod, a first discharge fork, a sealing gland B, a second discharge fork, a cover plate and packing. The sealing gland A is fixedly installed through bolts. The explosion-proof two-way valve is characterized in that the limit switch mounting plate is mounted on the valve disk shaft and is connected with the valve body through bolts. The explosion-proof two-way valve is additionally provided with the mounting plate which has the explosion-proof effect, so explosion of the valve body due to excessive pressure is avoided and use safety of the valve is greatly improved.

Description

technical field [0001] The invention relates to the technical field of explosion-proof valves, in particular to an explosion-proof two-way valve. Background technique [0002] As an accurate and reliable valve switch, the two-way valve provides reliable reversing for the flow of materials in the positive pressure pneumatic conveying pipeline system. It is widely used in the conveying and reversing of cement, cement raw meal, limestone, coal powder, bentonite, talc, barite and other powdery and granular materials. The two-way valve is divided into two modes of electric operation and manual operation, and is suitable for a material temperature of 204°C. The traditional two-way valve often explodes due to excessive pressure, which is extremely unsafe to use. Therefore, it is very necessary to design a two-way valve that can well solve the above problems. Contents of the invention [0003] The object of the present invention is to improve the above-mentioned deficiencies in...
