Product Details

One,Explosion proof electromagnetic pulse valve,Dust collector pulse valve,Spray pulse valveStructural description:
Explosion proof valve is mainly composed of valve body and insulation winding, and the valve body is made of zinc aluminum material casting.
The insulation winding of the explosion-proof valve is formed by molding and sealing the electromagnetic coil into an independent whole using high-performance engineering plastics. The sealing material has chemical, thermal, and mechanical stability. The thickness and spacing of the sealing layer of the formed insulation winding comply with the relevant provisions of GB3836.9.

The explosion-proof valve adopts a structure of gas electric isolation, and the gas path sealing performance is reliable.

3、 Key points of explosion-proof electromagnetic pulse valve, dust collector pulse valve, and spray pulse valve
When designing explosion-proof electromagnetic pulse valves and structures, key conditions such as the strength of the shell, the composition of the shell components, the material of the sealing agent, and limiting the surface temperature of the shell are taken into account to ensure explosion-proof performance.
When the explosion-proof electromagnetic pulse valve is working normally, the surface temperature of its shell should not exceed 130 ℃.
The exposed length of the power supply lead of the explosion-proof valve shall not be less than 1m.
When wiring explosion-proof electromagnetic pulse valves in hazardous areas, suitable conduit systems should be used to connect them to junction boxes or boxes with the same explosion-proof level.
The explosion-proof electromagnetic pulse valve is marked with the "Exmb II T4" symbol.
In the explosion-proof electromagnetic pulse valve circuit, it is necessary to equip electrical components that can achieve overload, short circuit and other protection, such as ceramic tube rapid fuses, but glass tube fuses must not be used.

The protection level of explosion-proof electromagnetic pulse valve is IP65

4、 The working principle of explosion-proof electromagnetic pulse valve:

The explosion-proof electromagnetic pulse valve consists of an explosion-proof electromagnetic pilot control device, a diaphragm, and an explosion-proof valve body. The area of the rear chamber of the diaphragm of the valve is larger than that of the front chamber. Under the force of pressure difference, the diaphragm is in the closed position. The electrical control instrument inputs an electrical signal, and the explosion-proof electromagnetic pilot control device receives the signal to suction and move the column, open the unloading hole, and quickly discharge the pressure gas in the rear chamber of the diaphragm. The pressure gas in the front chamber of the diaphragm lifts the diaphragm, opens the channel, and the pulse valve sprays. The electric pulse signal disappears, and the explosion-proof electromagnetic pilot control device immediately resets. The unloading hole is closed by the moving column, and the gas pressure and spring force in the rear chamber of the diaphragm close the channel, causing the valve to stop blowing. The damping hole on the diaphragm plays a role in damping the airflow when the pilot head is lifted and the gas pressure is unloaded. When the unloading hole is closed, the pressure gas quickly fills the rear chamber, causing the diaphragm to close the channel and stop blowing.
