ZCM-S with manual gas solenoid valve structure and principle of introduction

ZCM-S with manual gas solenoid valve 1. The solenoid valve is direct acting, widely used in urban gas, natural gas and other flammable gas pipelines. The valve structure is simple, good safety, long service life and so on. 2. Structure: the valve plate, stem, moving magnetic core, spring and movable joints, the use of rubber seal. Mostly in the low pressure or gas pipeline, according to the requirements can be equipped with manual switch, that is, when no power can also be manually turned on and off, you can also install the signal feedback. Manual switch mounted on the bottom of the valve, by the turbine, shaft composition, by moving up and down to open and close the valve plate. 3 working principle: gas solenoid valve is a direct-acting low-pressure solenoid valve open. The valve port gasket that controls the on-off of the medium is connected directly to the movable iron core through the valve rod. According to the state of the switch when the power switch can be divided into the normally closed solenoid valve and the normally open solenoid valve, normally closed solenoid valve, power off when the bit by armature weight, seal spring and medium pressure valve port seal, cut off The channel of charged media. After the solenoid coil is energized, the solenoid valve overcomes the deadweight of the armature and the sealing spring, and the force of the medium pressure sucks the movable iron core together with the valve port gasket to open the valve port and the controlled medium can be circulated. 4. Solenoid valve parameters: Working medium: gas, natural gas, liquefied gas and other flammable gases. Medium temperature: ≤60 degrees Working pressure: 0-0.05mpa Power supply voltage: AC220V The remaining specifications can be customized Service life: According to JB / T7352-94
