How does the pulse valve work?

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

right angle principle

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

2. When the pulse valve is energized, the valve core lifts upward under the action of electromagnetic force, the pressure relief hole opens, and the gas spurts out. Due to the effect of the constant pressure pipeline throttle hole, the outflow speed of the pressure relief hole is greater than the constant pressure of the decompression chamber. The inflow speed of the pressure tube gas makes the pressure of the decompression chamber lower than the pressure of the lower air chamber. The gas in the lower air chamber lifts the diaphragm, opens the blowing port, and performs gas blowing.

submerged principle

Submerged type principle: Its structure is basically the same as that of the right-angle pulse valve, except that it does not have an air inlet and uses the air bag directly as its lower air chamber. The principle is the same.
