[0003] The four-way flange joint is a pipe connection device, which is characterized by having four interfaces, which can connect multiple pipes and achieve their respective transportation purposes. At the same time, multiple pipes can also be gathered into one pipe. The four-way flange joint is composed of four connection ports, each of which is equipped with a flange. The two flanges are tightly connected together by bolts and nuts to achieve a reliable connection between the pipes. However, the existing four-way flange joint is not equipped with a filtering device, and the particles carried in the pipe may directly enter the joint. These particles are in contact with the inner wall of the flange for a long time, which will cause wear of the inner wall of the flange, thereby reducing its sealing performance and its service life. Therefore, we propose a new type of fluorine-lined four-way flange joint for converting medium flow. Summary of the invention

The position and size of the filter net 204 match the position and size of the installation groove 202, and the inner walls on both sides of the installation groove 202 fit the outer surfaces on both sides of the filter net 204. The filter net 204 is slidably connected with the filter box 201 through the installation groove 202. The position and size of the socket 206 match the position and size of the threaded hole 203. The bolt 209 penetrates the socket 206 and forms a threaded connection with the threaded hole 203. The shape of the filter net 204 is rectangular.

[0024] The effect achieved by the entire embodiment 1 is that when the flange joint body 1 is in use, the impurities in the fluid in the flange joint body 1 can be filtered through the filter screen 204, so that the filter screen 204 can absorb all the impurities. When the filter screen 204 needs to be disassembled and cleaned after long-term use, the bolts 209 can be rotated in the reverse direction first, so that the bolts 209 can be taken out from the threaded holes 203. After the two sets of bolts 209 are all removed, the handle 208 can be grabbed and pulled outward, so that the handle 208 can drive the The filter screen 204 can be pulled out from the installation groove 202, and then the filter screen 204 can be cleaned.
