[0002] The three-way valve is a control component in the fluid conveying system. It has the functions of shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow. The three-way valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media, while the reducing three-way valve can be installed for pipes with different inner diameters.

[0003] For example, patent CN208565668U discloses a three-way valve, including a valve body, a valve stem and an inlet connecting block, wherein a fluid inlet is provided at the left end of the valve body, wherein the fluid inlet is fixedly connected to the valve body, an inlet threaded interface is provided at the left side wall of the fluid inlet, wherein the inlet threaded interface is fixedly connected to the fluid inlet, a first outlet is provided at the right end of the valve body, wherein the first outlet is fixedly connected to the valve body, and an outlet threaded interface is provided at the right side wall of the first outlet.

[0004] When the above-mentioned three-way valve is in use, since there are a certain amount of impurities in the fluid in the pipeline, the impurities will move synchronously with the fluid. In the above-mentioned patent, since the filter screen is only fixed by the limit of the elastic buckle, although it can filter and block the impurities, it will cause the impurities to accumulate on one side of the filter frame in the long run, thereby forming a blockage. Moreover, when the impurities accumulate more, it may squeeze the filter screen to a certain extent, thereby causing displacement and affecting the subsequent filtering operation. For this reason, we propose a three-way valve with different diameters. Utility Model Content
