Abstract

The invention provides a manual self-locking double-protection double-control intelligent fire-fighting electromagnetic valve. The manual self-locking double-protection double-control intelligent fire-fighting electromagnetic valve comprises a valve body, a valve rod is installed in the valve body, the end, located on the outer side of the valve body, of the valve rod extends into an electromagnetic switch, a through groove concentric with the valve rod is formed in the valve rod, and an annular groove is formed in the outer surface of the end, located in the valve body, of the valve rod; and the annular groove communicates with the through groove through a through hole, an elastic compensation seal is fixedly connected to the end, located in the valve body, of the valve rod, a manual opening piece is installed on the outer surface of the valve body, and an emergency closing piece is installed in the electromagnetic switch. Compared with the prior art, the manual self-locking double-protection double-control intelligent fire-fighting electromagnetic valve has the following beneficial effects that manually controlling on-off of the electromagnetic valve, and an emergency closing function is achieved.

Description

technical field [0001] The invention is a manual self-locking double-guaranteed double-control intelligent fire-fighting electromagnetic valve, which belongs to the technical field of electromagnetic valves. Background technique [0002] Solenoid valve is an industrial equipment controlled by electromagnetic. It is an automatic basic component used to control fluid. It belongs to actuator and is used to adjust the direction, flow, speed and other parameters of medium in industrial control system. At present, the solenoid valve is generally controlled by electricity, and its on-off cannot be controlled manually, and it lacks an emergency shut-off function. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a manual self-locking double-guaranteed dual-control intelligent fire protection solenoid valve to solve the problems raised in the above-mentioned background technology. Disable function. ...
