Electromagnetic pulse valve detection method and detection system

Abstract

The invention discloses an electromagnetic pulse valve detection method and system. The method comprises the following steps: in step S1, an electromagnetic pulse valve receives pulse signals, the valve is opened, pressure gas inside an air manifold can be discharged, pressure of the air manifold falls to P1 from P2, and pressure of a valve chamber falls to P4 from P2; in steps S2, after the pulse signals are received, the valve is closed, the pressure of the air manifold returns to P2 from P1, and the pressure of the valve chamber returns to P2 from P4; in step S3, time T at which signals are sent by a pressure monitoring device is received via a signal receiving device, and a working state of the electromagnetic pulse valve is determined according to the time T at which the signals are sent by the pressure monitoring device; in step S4, if the time T at which the signals are sent by the pressure monitoring device is smaller than a preset threshold value, that the electromagnetic pulse valve works normally is determined. According to the electromagnetic pulse valve detection method and system, the signal receiving device is used for receiving electric signals from the pressure monitoring device, whether the electromagnetic pulse valve malfunctions can be determined according to the time at which the electric signals are sent from the pressure monitoring device, and convenience of detection can be realized.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic pulse valves, and in particular relates to an electromagnetic pulse valve detection method and detection system. Background technique [0002] The electromagnetic pulse valve is the core component of the dust cleaning system of the bag filter. It is mainly composed of electromagnetic coils, pilot head components, pilot valve seats, valve covers and valve seats. Or other moving components are the most important elements that determine the performance and life of the valve, because they are in high-pressure, high-frequency reciprocating motion for a long time, long-term work will cause the diaphragm of the diaphragm component to rupture, and the rubber holder of the diaphragm component The fatal defects such as knock-out, aging, spring breakage and other fatal defects seriously affect the quality of the electromagnetic pulse valve.

[0002] The electromagnetic pulse valve is the core component of the dust cleaning system of the bag filter. It is mainly composed of electromagnetic coils, pilot head components, pilot valve seats, valve covers and valve seats. Or other moving components are the most important elements that determine the performance and life of the valve, because they are in high-pressure, high-frequency reciprocating motion for a long time, long-term work will cause the diaphragm of the diaphragm component to rupture, and the rubber holder of the diaphragm component The fatal defects such as knocked damage, aging, spring breakage, etc. seriously affect the quality of the electromagnetic pulse valve.

[0003] In the prior art, if the electromagnetic pulse valve breaks down, it is necessary to find the failed electromagnetic pulse valve first, then disassemble the failed electromagnetic pulse valve, and then test the components of the electromagnetic pulse valve in turn. There are many components in the electromagnetic pulse valve , the detection is more cumbersome, and the disassembly and assembly are inconvenient, which greatly reduces the detection efficiency
