Pulse valve performance online detecting device

Abstract

The invention relates to a pulse valve performance online detecting device. The pulse valve performance online detecting device comprises a pressure tapping assembly, a pressure sensor and a data acquisition display unit; the pressure tapping assembly is mounted on a pulse valve and is communicated with a venting hole of the pulse valve; a pressure sensor mounting hole is arranged on the pressure tapping assembly; the pressure sensor is arranged in the pressure sensor mounting hole of the pressure tapping assembly and is connected with the data acquiring display unit; the pressure sensor is used for acquiring pressure signals on the venting hole of the pulse valve and transmitting the pressure signals to the data acquiring display unit; and the data acquiring display is used for receiving the injection pressure variation data of the pulse valve and displaying the injection pressure variation data in form of curves. Compared with the prior art, the pulse valve performance online detecting device provided by the invention has the advantage that various performance indexes of the pulse valve can be accurately determined online.

Description

technical field [0001] The invention relates to a pulse valve detection device, in particular to an pulse valve performance on-line detection device. Background technique [0002] The pulse valve is mainly used in the bag filter, which uses the change of gas pressure to blow the compressed gas in the air bag (gas distribution box) into the air chamber of the bag filter and make the solid dust attached to the filter material It is a key accessory of the bag filter to achieve the purpose of dust removal or collection. It is widely used in the field of dust control and collection in various industries. [0003] The customary pulse valve performance test is usually carried out on the special detection device of the manufacturer. The test pressure point is set at the outlet of the pulse valve. After collecting the outlet pressure change curve, the performance indicators of the pulse valve are judged. If the pulse valve After installed on the site of the dust collector, the only...

[0003] The customary pulse valve performance test is usually carried out on the special detection device of the manufacturer. The test pressure point is set at the outlet of the pulse valve. After collecting the outlet pressure change curve, the performance indicators of the pulse valve are judged. If the pulse valve After being installed on the site of the dust collector, the only way to perform performance testing is to stop the machine and disassemble the pulse valve before sending it for inspection. This requires a very large workload and causes losses to the user, and it cannot achieve the purpose of online testing and observation of the pulse valve’s operating performance.
