Supply a full range of pulse valve is divided into rectangular pulse valve and submerged pulse valve angle valve works pulse pressure gas from the intake port access, go to the next chamber, 1, when the pulse valve without electricity, the gas passes through the upper and lower housings and wherein the constant-pressure pipe to a vacuum chamber orifice, the valve under the action of the spring block the relief hole, the gas will not discharge, so that the gas pressure chamber and a lower chamber pressure line, and in the spring action Next, the diaphragm will blow ports blocked, not out of gas. 2, when the pulse valve is energized, the spool in the electromagnetic force of the lift, pressure relief hole open, the gas emitted, because the role of the orifice constant pressure piping, pressure relief hole faster than a decompression chamber constant outflow pressure pipe flow velocity of gas, so that the vacuum chamber pressure is lower than the pressure of the gas chamber, the gas chamber of the gas from the top of the diaphragm to open the blow port, the gas injection. Submerged pulse valve works its structure and rectangular pulse valve basically the same, but no air intake, directly under the air bag as its air chamber, the principle is the same.
