A purge electromagnetic pulse valve for bag dust collector

Abstract

The invention relates to a purging electromagnetic pulse valve used for a bag type dust collector. The purging electromagnetic pulse valve comprises a guide part (2), a valve body (5) and a valve core (6), and also comprises a driving coil (1), a guide spring (3), a movable iron core (4), a spring (7) and a pressing piece (8), wherein the tip of the valve body (5) has three ports including a port I connected with a compression air source, a port II connected with a pressure measuring instrument and a port III connected with a pressure tap of the bag type dust collector; a cavity, a channel a communicating the cavity with the port I, a channel b communicating the cavity with the port II and a channel c communicating the cavity with the port III are arranged inside the valve body (5); the valve core (6) is arranged in the cavity and is connected with the spring (7); the spring (7) is mounted on the pressing piece (8); the channel c is arranged in the pressing piece (8); the spring (7) pushes the valve core (6) to abut against and seal the bottom of the channel a; the guide part (2) is connected with the guide spring (3) which pushes the movable iron core (4) to abut against and seal the top of the channel a; and the driving coil (1) is mounted on the guide part (2). Compared with the prior art, the purging electromagnetic pulse valve used for the bag type dust collector has the advantages that a pressure measuring device is protected during a pressure tap purging process and the like.

Description

technical field [0001] The invention relates to an electromagnetic pulse valve, in particular to a purge electromagnetic pulse valve for a bag type dust collector. Background technique [0002] The bag filter is widely used in the field of dust control and collection in various industries. It is very important for the bag filter to measure the differential pressure value of the gas in the upper and lower boxes of the dust collector, because the lower box is full of unfiltered Dust-laden gas, the pressure-taking hole on the lower box is often blocked, and the user needs to purge the pressure-taking port manually or with compressed gas, but the compressed air often reaches the pressure measuring instrument through the connecting pipeline, due to the pressure measuring instrument The pressure value is much smaller than the pressure value of the compressed gas, which can easily cause the pressure measuring instrument to fail, and eventually cause the dust collector to fail or ev...
