China wholesale Valve Star - DMF type electrovanne pneumatic solenoid dust diaphragm right angle pulse solenoid valve – Xintian

Product Description

Pulse valves are divided into right-angle pulse valves and submerged pulse valves.

Right angle principle:

1. When the pulse valve is not energized, the gas enters the decompression chamber through the constant pressure pipes of the upper and lower shells and the throttle holes in them. Because the valve core blocks the pressure relief holes under the action of the spring, the gas will not be discharged. Make the pressure of the decompression chamber and the lower air chamber the same, and under the action of the spring, the diaphragm will block the blowing port, and the gas will not rush out.

2. When the pulse valve is energized, the valve core is lifted up under the action of electromagnetic force, the pressure relief hole is opened, and gas is ejected. Due to the effect of the constant pressure pipe orifice, the outflow speed of the pressure relief hole is greater than that of the pressure relief chamber. The inflow speed of the pressure pipe gas makes the pressure of the decompression chamber lower than the pressure of the lower gas chamber, and the gas in the lower gas chamber pushes up the diaphragm, opens the blowing port, and performs gas blowing.

Submerged principle: Its structure is basically the same as the right-angle pulse valve, but there is no air inlet, and the air bag is directly used as its lower air chamber. The principle is also the same.
