Description

1. Technical field

[0001] The invention relates to a performance detection device for a pulse valve and a method for detecting the performance of a pulse valve using the device. The pulse valve of the present invention is a diaphragm valve for rapid release of compressed gas used in environmental protection for pulse jet cleaning of bag filters. powered off. 2. Technical background

[0002] The bag filter is a kind of dust removal equipment that uses the filter bag made of filter cloth to filter and separate the dust in the dusty gas. It has two basic working states of filtering and dust removal. During filtration, dust is collected on the outer surface of the filter bag, and after the filtration resistance gradually increases to a certain value, it needs to be cleaned to maintain the continuous filtration capacity of the dust collector. A common and effective way of dust removal is pulse jet dust removal, that is, the compressed gas in the air bag is quickly released into...

Embodiment Construction

[0041] like figure 1 , the pulse valve performance testing device consists of air compressor 1, gas storage tank 2, oil-water separator 3, pressure reducing valve 4, pressure-stabilizing air bag 5, pulse valve 6 under inspection, blowing pipe 7, pressure sensor 8, and target 9 , an acceleration sensor 10, a data acquisition card 11, and a computer 12.

[0042] The air compressor 1, the gas storage tank 2, the oil-water separator 3 and the pressure-stabilizing air bag 5 are connected with a compressed air pipeline, and a pressure-reducing valve 4 is set on the pipeline between the oil-water separator 3 and the pressure-stabilizing air bag 5.

[0043] Set the blowing pipe 7 and the target 9 directly below the pulse valve 6 under inspection, the blowing pipe 7 is aligned with the target 9, and the wall of the blowing pipe 7 has a small hole;

[0044] Pressure sensor 8 is set respectively on the pressure-stabilizing air bag 5 and the opening of blowing pipe 7, and acceleration se...
