Description

Slide valve control assembly, electromagnetic pulse valve using slide valve control assembly and working method
The technical field is as follows:
the invention relates to a slide valve control assembly, an electromagnetic pulse valve using the slide valve control assembly and a working method.
Background art:
the electromagnetic pulse valve is a generating device which generates pulse vibration airflow in the bag type dust collector to facilitate dust removal, and the electromagnetic pulse valve and a pulse injection control instrument form a dust removal injection system of the dust collector; the selection of the high-performance electromagnetic pulse valve is an important measure for ensuring the blowing effect of the bag type dust collector, and meanwhile, the high-quality bag type dust collector can be ensured only by completely eliminating the adverse factors of the blowing system of the bag type dust collector, which influence the blowing effect, so that the high dust cleaning effect is achieved.
The pulse valve is controlled by a pilot valve such as electromagnetism or pneumatics, and can instantly open and close a diaphragm valve which is used for generating pulses by a high-pressure air source.
The working principle of the pulse valve is as follows:
as shown in fig. 1: high-pressure gas is introduced from a gas inlet X1 and enters a front gas chamber X2;
1. when an electromagnetic coil X3 of the electromagnetic pulse valve is electrified, an armature component X4 is lifted upwards under the action of electromagnetic force, a pressure relief hole X5 is opened, gas is discharged, due to the throttling action of a diaphragm throttling hole X6, the gas flow flowing out of the pressure relief hole is larger than the gas flow flowing into a rear gas chamber X7 through the throttling hole, the pressure of the rear gas chamber is lower than that of a front gas chamber, the gas pressure of the front gas chamber jacks up a diaphragm X8, a blowing opening of a pulse gas outlet is opened, and gas is blown.
2. When the electromagnetic coil of the electromagnetic pulse valve is not electrified, gas enters the rear air chamber through the throttling hole in the diaphragm between the upper shell and the lower shell, the armature component blocks the pressure relief hole under the action of the spring, the gas cannot be discharged, the pressure of the rear air chamber X7 is consistent with that of the front air chamber X2, and high-pressure gas is not sprayed out under the action of different pressure areas of the pressure spring X10 and the upper front air chamber of the diaphragm, so that primary pulse gas is formed.
The problems that can appear when the above-mentioned current pulse valve is used:
1. because the throttling hole on the control valve diaphragm X8 is smaller (about phi 1.5), the inflow of the rear air chamber to the gas in the control air chamber is reduced due to the blockage of pollutants such as dust and the like, the gas supply time of the rear air chamber to the control air chamber is prolonged, the diaphragm blocks a blowing opening sprayed by a pulse gas outlet to be unfavorable, and the pulse waveform is slowed down, so that the dust removal effect of the dust remover is reduced;
2. because the time for the front air chamber to supply air to the rear air chamber is prolonged, the closing of the diaphragm is delayed, a large amount of high-pressure gas escapes from the pulse gas outlet, and the energy is wasted;
3. the control membrane is easy to crack and lose efficacy due to the flushing of high-pressure gas because the membrane with the throttling hole is opened.

3) The pilot valve piston is pushed to the direction of a return spring under the action of compressed air entering the rear separation cavity through the vertical air inlet channel and the duct, and simultaneously pushes the control valve core to the direction of the return spring, so that the pressure of the rear separation cavity is the same as that of the pressure relief duct; the gas in the rear gas chamber is exhausted through the pressure relief pore passage;
4) Because the gas in the rear gas chamber is rapidly discharged, although the throttling hole is supplemented, the gas pressure of the front gas chamber still rapidly overcomes the acting force of the diaphragm pressure spring to jack the diaphragm assembly, and the gas in the front gas chamber is rapidly flushed out from the pulse gas outlet;
5) The electromagnetic coil of the electromagnetic valve is restricted by the controller to be powered off, the armature assembly is controlled to be closed under the action of the armature spring, air sources communicated with a second transverse channel, a vertical air inlet channel and a pore channel of the pilot valve are blocked, a piston of the pilot valve and a control valve core restore to original states under the action of a return spring, and the vertical air inlet channel is closed to be communicated with the front separation cavity and the rear separation cavity;
6) Because the gas discharge of the rear gas chamber is blocked, the gas of the rear gas chamber is quickly supplemented by the throttling hole of the diaphragm, when the gas pressure of the rear gas chamber is equal to that of the front gas chamber, the diaphragm assembly is quickly closed under the adsorption action of the pressure spring and the gas jet, and the pulse gas discharge port forms a primary pulse gas source.
2. The operation method of the electromagnetic pulse valve using the slide valve control unit according to claim 1, wherein: the elastic diaphragm comprises a diaphragm assembly and a diaphragm pressure spring, the diaphragm assembly comprises a central diaphragm used for separating a front air chamber and a rear air chamber and a pressing block clamped in the middle of the central diaphragm, the pressing block covers the upper end face of the pulse gas exhaust port, and the diaphragm pressure spring is arranged on the upper end face of the pressing block in an overhead mode.
3. The operation method of the electromagnetic pulse valve using the slide valve control unit according to claim 2, characterized in that: and the central diaphragm is provided with a throttling hole.
