Y-type filter is an indispensable filtering device in the pipeline system of conveying fluid medium. Y-type filter is usually installed at the inlet end of pressure reducing valve, pressure relief valve, stop valve (such as the inlet end of indoor heating pipeline) or other equipment to remove impurities in the medium, so as to protect the normal use of valves and equipment. Y-type filter has advanced structure, small resistance and convenient blowdown.
Y-type filter is mainly composed of connecting pipe, main pipe, filter screen, flange, flange cover and fastener. When the liquid enters the basket through the main pipe, the solid impurity particles are blocked in the basket, and the clean fluid is discharged through the basket and the outlet of the filter. The reason why the filter screen is made into the shape of the basket with cylindrical surface is to increase its strength, which is stronger than the single-layer net. The flange cover at the lower end of the Y interface can be unscrewed to remove the particle impurities deposited in the basket on a regular basis.
Before installing the filter, the threaded connection surface of all pipes shall be cleaned carefully, and proper amount of pipe sealant or Teflon tape (polytetrafluoroethylene) shall be used. The end thread shall not be treated to avoid sealant or Teflon tape entering the pipeline system. The filter can be installed horizontally or vertically downward.
