DMF-Z-20 DMF-Z-25 DMF-Z-40 DMF-Z-50 Electromagnetic Pulse Solenoid Valve Diaphragm Control Valve AC220V DC24V
1. Working Principle
Through the wire to the solenoid valve body coil input positive pulse signal, the coil generated by the work of the magnetic flux, so that the moving core suction, open the valve. When stopping the positive pulse signal input, the dynamic core release, the dynamic core under the action of the spring force to return to the initial state, close the valve in addition to the self-holding type, stop input positive pulse or power failure can also be maintained, need to input a negative pulse signal in order to reset; Pulse solenoid valve working principle, is the use of electrical appliances, the pulse is converted into mechanical pulsation, so that the pulsating gas of the powerful energy into momentum, in a short time Release to produce a huge impulse, with plc control of its pulse interval should be determined according to the rated gas pressure recovery time.
2. Working Condition
(1) According to the type of power supply, the choice of AC and DC solenoid valves. Generally speaking, AC power supply is convenient.
(2) in a corrosive or explosive environment should be prioritized according to the safety requirements of the selection of corrosion-resistant.
(3) If the environmental space is restricted, please select the multi-function solenoid valve, because it eliminates the bypass and three manual valves and easy online maintenance.
(4) The power supply voltage fluctuation is usually used for AC +%10%. -15%, DC allows ±%10 or so, such as overshooting, must take measures to stabilize the voltage or special order requirements.
(5) The maximum and minimum temperature of the environment should be selected within the permissible range, if there is excessively poor need to make special orders.
(6) Electromagnetic pulse valve power conditions.
(7) The environment is often vibration, bumps and shocks and other occasions should be selected special varieties, such as marine solenoid valve.
(8) Voltage specifications with as much as possible to prioritize the selection of AC220V.DC24V.
(9) high relative humidity and water droplets in the environment and rain and other occasions, should choose waterproof solenoid valve.
(10) should be selected according to the power capacity of the rated current and power consumption. Must pay attention to AC start VA value is high, in the capacity is not enough should be preferred to use indirectly guided solenoid valve.
