High temperature solenoid valve solenoid coil plugged in, the crankshaft is raised, accompanied by the drive shaft gradually rotate, this fitness movement efficacy in the pilot valve and open the main valve; after the power is turned off, in the flow coil own weight and back to the spring efficacy, half on the pilot valve, the pilot valve off, by the pressure difference to turn off the main valve.
Normally closed: when the solenoid coil plugged in power, the pilot valve spool suction, pilot hole open, valve on the pressure relief, piston rod by the lower cavity material working pressure to promote, solenoid valve open; when the solenoid coil off power, the pilot valve spool by the spring calibration, pilot hole off, valve upper cavity by the piston rod throttle valve hole to increase pressure and calibration spring propulsion, valve off.
On and off: When the solenoid coil is plugged in, the pilot hole is turned off, the upper chamber of the valve is increased by the piston rod throttling valve hole to increase the pressure and the pushing force of the calibration spring, and the solenoid valve is turned off. When the solenoid coil off power, the pilot spool by the spring calibration, pilot hole open, valve upper cavity pressure relief, piston rod by the lower cavity material working pressure to promote, the solenoid valve open.
High temperature solenoid valve installation precautions
1, before installing the solenoid valve: (1) please read the article this instructions for use, domestic solenoid valve and verify the solenoid valve model specifications and specifications; (2) cleaning pipeline.
2, solenoid valve installation orientation: material flow orientation should be the same as the arrow orientation on the oil circuit board; part of the magnet coil should be vertical up.
3, no need to install this valve in the pipeline low trap, to prevent the accumulation of vapor condensate, residue, etc. in the valve and prevent the posture.
4, the valve can not be applied in the risk of explosion.
5, the solenoid valve installation to leave a certain indoor space, water purifier solenoid valve to facilitate the discharge of heat and routine maintenance and maintenance on time.
