Y strainer is an indispensable device in the medium pipeline. It is usually installed at the inlet of pressure reducing valve, pressure relief valve, constant water level valve, square filter and other equipment. The y strainer has the advantages of advanced structure, small resistance and convenient discharge. The suitable medium of y strainer can be water, oil and gas. Generally, the water supply network is 18 ~ 30 mesh, the ventilation network is 10 ~ 100 mesh, and the oil network is 100 ~ 480 mesh. Basket filter is mainly composed of nozzle, main pipe, filter basket, flange, flange cover and fastener. When the liquid enters the blue filter through the main pipe, the solid impurity particles are blocked in the blue filter, and the clean fluid is discharged from the filter outlet through the blue filter.

When the liquid enters the blue filter through the main pipe, the solid impurity particles are blocked in the blue filter, and the clean fluid is discharged from the filter outlet through the blue filter.

The y strainer is generally composed of cylinder, stainless steel filter screen, sewage discharge part, transmission device and electrical control part. Of course, the shape of the strainer is not the same. It can also be changed into different shapes. For example,  y strainer, as the name suggests, is like the shape of the letter Y. Y strainer is usually composed of brass valve body, stainless steel filter screen and hot pressed fiber gasket. Because of its advanced structure, low resistance and convenient sewage discharge, it is favored by many consumers.

The principle of Y-type strainer is divided into working principle and testing principle. The working principle is that when the diameter of the impurity is larger than that of the y strainer, the impurity will be intercepted by the strainer screen and attached to the strainer screen. The clean fluid will flow out of the filter screen, and then the filter screen can be cleaned regularly. The test principle of y strainer is relatively complex, including: bubble point method test principle; diffusion flow method test principle; why diffusion flow method is better; water intrusion method test principle.

Strainer has been applied in many industries, such as agricultural irrigation, water supply filtration system, circulating water filtration, petrochemical, electromechanical, pharmaceutical wastewater ion exchange pretreatment, etc., and y strainer plays an important role in the treatment of domestic wastewater and industrial wastewater. With the advantages of design and application, Y-type filter has been favored.

Y strainer in various industries in the application of effective treatment of a large number of domestic and industrial sewage, so that the valuable water resources have been effectively reused, saving a lot of water resources, is indispensable. Moreover, the water quality after treatment by Y strainer not only meets the national discharge standard, but also achieves the purpose of repeated and recycling.
