Description

Technical Field

[0001] The utility model relates to the technical field of pulse valve detection, in particular to a pulse valve working detection device. Background Art

[0002] A pulse valve is a device used to control the flow of a fluid (usually a gas or liquid). Its working principle is based on controlling the on / off state of the fluid through a periodic pulse signal. This valve usually consists of one or more controllable pulse nozzles. When a pulse signal is applied to the valve, the nozzle opens or closes, thereby allowing or preventing the fluid from passing through.

[0003] Upon investigation, it was found that the Chinese utility model patent with publication number CN203309320U disclosed a pulse valve working detection device, which realizes signal acquisition and real-time monitoring of whether the pulse valve is faulty by forming a passage through the movable metal sheet and the static metal sheet, thereby realizing real-time detection of the pulse valve, eliminating manual troubleshooting, and improving the accuracy of judging the working status of the pulse valve; however, during actual use, the pulse valve may have a slight air leakage. If the air leakage is not serious, the movable metal sheet can still be driven to contact and energize the fine metal sheet during the exhaust process, resulting in inaccurate detection results, which makes it inconvenient for staff to make judgments.

[0004] Therefore, the utility model provides a pulse valve operation detection device to solve the above problems. Utility Model Content
