Detailed Description

the present invention will be further explained with reference to the accompanying drawings.

As shown in figure 1, the high-pressure Y-shaped filter comprises a filter pipe 1, wherein one end of the filter pipe 1 is fixedly provided with a pipe cover 2, the other end of the filter pipe 1 is fixedly connected with a first main pipe 3, and the side wall of the filter pipe 1 is fixedly connected with a second main pipe 4. The liquid medium flows in from the first main pipe 3, passes through the filtering function of the device in the filter pipe 1 and flows out from the second main pipe 4. The liquid medium is high-pressure liquid, the shape of the pipeline for circulating the liquid is required, the pipeline for circulating the high-pressure liquid is preferably horizontally arranged, and the inflow pipeline and the outflow pipeline are positioned on the same horizontal height. Therefore, the filter pipe 1 is communicated with the first main pipe 3 through the arranged first elbow 8, and the first elbow 8 is a 45-degree elbow; the filter pipe 1 is communicated with the second main pipe 4 through a second elbow 9, and the second elbow 9 is a 45-degree elbow, so that the filter pipe 1, the first main pipe 3 and the second main pipe 4 are connected to form a Y shape.
