Y-type filters are indispensable filtering devices in pipeline systems for conveying media. Y-type filters are usually installed at the inlet end of pressure reducing valves, relief valves, constant water level valves, or other equipment to remove impurities from the media and protect the normal operation of valves and equipment. Y-type filters feature a simple structure, low resistance, and convenient排污 (drainage). Y-type filters can be used for media such as water, oil, and gas. Generally, the mesh for water is 18~30目 (mesh), for gas 10~100目, and for oil 100~480目. Basket filters mainly consist of接管 (connector),主管 (main pipe),滤篮 (filter basket),法兰 (flange),法兰盖 (flange cover), and紧固件 (fasteners). When liquid enters the filter basket through the main pipe, solid impurity particles are trapped in the filter basket, while clean fluid passes through the filter basket and is discharged from the filter outlet.
