Abstract

The invention relates to an efficient electromagnetic pulse valve and a working method thereof. The efficient electromagnetic pulse valve comprises an upper valve seat and a lower valve seat, whereinan air inlet channel is formed in the edge of the lower valve seat, an air outlet channel is formed in the center of the lower valve seat, a first diaphragm assembly is arranged between the upper valve seat and the lower valve seat to partition the air inlet channel and the air outlet channel, a first air chamber is arranged between the first diaphragm assembly and the upper valve seat, a plurality of air channels used for enabling the air inlet channel to communicate with the first air chamber are formed in the lower valve seat along the central axis of the lower valve seat in an array mode,mounting seats are arranged in the air channels, valve rods capable of moving axially relative to the mounting seats are arranged in the centers of the mounting seats in a penetrating mode, through holes enabling the upper sides and the lower sides of the mounting seats to communicate with each other are further formed in the mounting seats, valve bonnets used for sealing the upper ends of the through holes are arranged at the upper ends of the valve rods, and compression springs used for jacking the valve bonnets to be at the upper ends of the mounting seats are further arranged at the upperends of the valve bonnets. According to the efficient electromagnetic pulse valve and the working method thereof, a throttling hole does not need to be arranged on a valve diaphragm, so that the valveis prone to blockage during working, and the circulation efficiency of airflow is improved.

Description

technical field

[0001] The invention relates to a high-efficiency electromagnetic pulse valve and its working method. Background technique

[0002] The pulse valve refers to the diaphragm valve that is controlled by the pilot valve such as electromagnetic or pneumatic, and can open and close the high-pressure air source in an instant to generate pulses. The pulse valve is the main component of the bag filter. The existing pulse valve communicates with the upper and lower air chambers of the diaphragm by setting an orifice on the diaphragm. When working, when the electromagnetic coil of the control valve is energized, the armature assembly is lifted upward under the action of electromagnetic force, and the pressure is released. The hole is opened and the gas is discharged. Due to the throttling effect of the diaphragm orifice, the gas flow out of the pressure relief hole is greater than the gas flow of the gas flowing into the rear air chamber through the orifice, so that the...
