Anti-explosion emergency cut-off gas solenoid valve characteristics;

Air-tight explosion-proof solenoid valve spool adopts stainless steel piston structure, which can be switched quickly. Reasonable sealing material and structure, good sealing performance, no leakage. Explosion-proof solenoid valves are used for emergency gas shut-off up to 1 million times. Restarting after a long pause is also sensitive. Interface size is generally industry standard, users can customize the specific interface of the starting solenoid valve. High performance sealing piston ring solenoid valve, including jacketed and combined two. Normally closed emergency cut off gas explosion-proof solenoid valve quickly closed after power failure; When the valve starts again, the solenoid valve equipment will not automatically open, must be manually pulled to maintain the open state; Energy saving, coil to maintain 15W power, temperature below 10℃, long time power supply; Good sealing, zero leakage. [Signal feedback] When the valve is open, the signal public line is connected with the open signal line, when the valve is closed, the signal public line is connected with the closed signal line. Emergency cut open gas explosion-proof solenoid valve; Emergency power gas explosion-proof solenoid valve, equipped with gas alarm. The principle is that when the detector finds flammable gas leakage, it should immediately close the solenoid valve through the output signal of the host machine, and quickly close the solenoid valve to cut off the gas supply to prevent accidents. Emergency cut-off gas solenoid valve photo.

Working principle of normally closed emergency cut-off gas solenoid valve:

When opening the solenoid valve, first make the coil energized, and then tighten the protective sleeve on the valve top, force to pull outward, and then open the solenoid valve, and then put the protective sleeve on the in-situ protection handle. When the solenoid valve needs to be closed, the coil immediately power off, and immediately close the solenoid valve.

Working principle of normally open emergency cut-off gas solenoid valve;

When the valve needs to be opened, unscrew the protective cover (the protective cover has a threaded hole in the middle as a handle) and pull hard to open the valve.

If the valve needs to be closed and the coil is energized for no more than 1 second, the valve should be closed quickly within 65 ms.

Correct use of emergency cut-off gas solenoid valve;

The gas emergency cut-off solenoid valve should be installed behind the main indoor intake valve for future maintenance.

After the installation of the gas emergency cut-off valve, it is necessary to conduct multiple tests through the introduction of media to confirm that the valve is normal before it can be formally used.

Regular cleaning of large valve inside and outside and armature suction surface dirt.

When not in use, the emergency cut-off explosion-proof solenoid valve is removed from the pipeline, and the internal components should be tested and stored with compressed air.

5. When the solenoid valve is not used for a long time, the manual valve should be closed first, and then the manual valve should be opened. The condensed water should be cleaned and tested for many times.
