Electromagnetic pulse valve

Electromagnetic pulse valve refers to a diaphragm valve that is controlled by a pilot valve such as electromagnetic or pneumatic, and can open and close a high-pressure gas source in an instant to generate pulses.

Role of solenoid pulse valve.

It is to control the size of oil pressure in the oil circuit. Generally installed in the main oil circuit or damper back pressure oil circuit, in order to reduce the oil pressure impact when shifting gears and locking and unlocking, so that the equipment operation to maintain a smooth state.

According to the angle of the valve inlet and outlet and the form of air inlet can be divided into three kinds.

a) Right-angle electromagnetic pulse valve: the valve body inlet and outlet at right angles, directly controlled by the electrical signal diaphragm valve.

b) Straight-through electromagnetic pulse valve: the valve body inlet and outlet into 180 degrees, directly by the electrical signal control of the diaphragm valve.

c) Submerged electromagnetic pulse valve: valve body inlet submerged in the air bag, directly by the electrical signal control of the diaphragm valve.

In addition to the conventional three solenoid valves, there is a rotary blowing with a large diameter ultra-low pressure electromagnetic pulse valve.

Working Principle

Diaphragm electromagnetic pulse valve is divided into the front and back of the two air chamber, when connected to the compressed air through the throttle hole into the back of the air chamber, the pressure of the back of the air chamber will be the diaphragm close to the valve's output port, the electromagnetic pulse valve is in a ‘closed’ state. Pulse blowing control instrument signal disappears, electromagnetic pulse valve armature reset, after the air chamber bleed hole closed, after the air chamber pressure rises so that the diaphragm close to the valve outlet, electromagnetic pulse valve is in the ‘off’ state.

Environmental requirements

Pulse dust collector cleaning unit electromagnetic pulse valve in use should strictly abide by the environmental requirements, electromagnetic pulse valve can not be normal and smooth operation of the electromagnetic pulse valve environmental conditions.

1, according to the type of power supply, respectively, the choice of AC and DC solenoid valve. Generally speaking, AC power supply is convenient.

2, the environment of high relative humidity and water dripping rain and other occasions, should choose the solenoid valve.

3, in a corrosive or explosive environment should be used in accordance with the requirements of priority selection of etching solenoid valve.

4, electromagnetic pulse valve power conditions.

5, the power supply voltage fluctuations are usually selected AC +%10%. -15%, DC allows ±%10 or so, such as overshooting, must take measures to stabilise the voltage or ordering requirements.

6, the environment is often vibration, bumps and shocks and other occasions should be selected species, such as marine solenoid valve.

7, the voltage specification with as far as possible priority selection of AC220V, DC24V.

8, should be selected according to the power capacity of the rated current and power consumption. Must pay attention to AC start VA value is higher, in the lack of capacity should be preferred to use indirectly guided electromagnetic pulse valve.

9、If the environment space is limited, please choose the multi-function solenoid valve, because it eliminates the bypass and three manual valves and easy online maintenance.
