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.
