Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a pressure compensation structure for filters. Background Art

[0002] The main function of the pressure compensation structure for the filter is to stabilize the pressure inside the filter and at the output end, ensuring that the filtration effect and system operation are not affected in the case of pressure fluctuations. Its purpose is to improve the stability and reliability of the filtration system and reduce the decrease in filtration efficiency or equipment damage caused by pressure changes.

[0003] The pressure compensation structure for filters usually consists of a pressure reducing valve, a shuttle valve and a feedback control system. During operation, the pressure reducing valve first adjusts the input pressure according to the preset pressure value to ensure stable output pressure. The shuttle valve then introduces the pressure on the high-pressure side into the low-pressure side through an internal mechanism to compensate for the pressure difference caused by load changes. The feedback control system monitors the output pressure in real time and adjusts the opening of the pressure reducing valve to achieve precise pressure control.

[0004] However, in actual use of the above equipment, most filters will produce a certain amount of scale in the filter cartridge after filtration, which is difficult to clean. In view of this, we propose a pressure compensation structure for the filter. Utility Model Content
