The submerged Electromagnetic Pulse Valve adopts the installation method submerged in the gas bag, so it is called the submerged type. Compared with other structural forms, it reduces the flow resistance and reduces the pressure of the gas source, so it can be applied to the situation of low pressure and can reduce the energy consumption and prolong the life of the diaphragm. The working principle of the submerged electromagnetic pulse valve is that the diaphragm makes the pulse valve before and after the two chambers. When the compressed air is connected, the compressed air enters the rear air chamber through the throttle hole, and the pressure of the air chamber will close the diaphragm to the outlet of the valve, and the pulse valve is in the "closed" state.
When the electrical signal of the pulse controller moves the armature of the pulse valve, the gas chamber is open after the valve, the rear air chamber is quickly lost, the diaphragm moves, the compressed air is blown through the valve outlet, and the pulse valve is in the "open" state. The compressed air flow is sprayed instantaneously at this moment.
The electric signal of the pulse controller is disappearing, the armature of the pulse valve is reset, the air chamber is closed, the pressure of the rear air chamber is raised and the diaphragm is close to the valve outlet, and the pulse valve is in the "closed" state.
When the electromagnetic pulse valve is used, the environmental conditions are very important, which is related to the normal and smooth operation of the electromagnetic pulse valve. The environment conditions of the electromagnetic pulse valve:
1, according to the type of power supply, AC and DC solenoid valves are selected respectively. Generally speaking, AC power supply is convenient to use.
2, in corrosive or explosive environments, corrosion resistance should be preferred according to safety requirements.
3, if the environment space is restricted, please use the multi-function solenoid valve, because it eliminates bypass and three manual valves and is convenient for online maintenance.
4, the power supply voltage fluctuations usually AC +%10%.-15%, DC tolerance of about%10, if ultra poor, must take measures to stabilize or put special order requirements.
5, the highest and minimum temperature of the environment should be selected within the allowable range. If there is excess deviation, special orders should be put forward.
6, the power condition of the electromagnetic pulse valve
7, special occasions such as vibration, bump and impact should be selected in the environment, such as marine solenoid valves.
8, voltage specifications are preferred to AC220V.DC24V.
9, in the environment where relative humidity is high and water droplets are dripping, we should choose waterproof solenoid valves.
10, the rated current and power consumption should be selected according to the power supply capacity. Attention should be paid to the higher VA value when AC starting, and the indirect guided solenoid valve should be preferred when the capacity is insufficient.
