[0023] The fixed sleeve 201, the adjustment plate 202 and the guide rod 205 are all made of aluminum alloy, the fixed sleeve 201 is designed in a T-shaped structure, the reset spring 206 is fixedly connected to the fixed sleeve 201, the sealing gasket 203 and the sealing plug 209 are both made of silicone, the guide tube 204 is designed in a Y-shaped structure, the guide rod 205 is slidingly connected to the fixed sleeve 201, the reset spring 206 is provided with two groups, the collecting bottle 208 passes through and extends to the outside of the fixed sleeve 201, the guide tube 204 passes through and extends to the inside of the external threaded sleeve 207, the outer wall of the sealing plug 209 is fixedly connected with a pull ring, the sealing plug 209 is pulled out of the fixed sleeve 201 by pulling the sealing plug 209, and the three-valve group is The body 1 is installed in the pipeline, and the hydraulic fluid flows into the three-valve group body 1 through the fixed sleeve 201. When the hydraulic fluid pressure in the pipeline increases, the pressure of the hydraulic fluid flowing in the fixed sleeve 201 on the regulating plate 202 exceeds the elastic force of the return spring 206 on the regulating plate 202. The regulating plate 202 moves downward under the action of the pressure difference on both sides. The downward moving regulating plate 202 no longer blocks the guide tube 204. The hydraulic fluid in the fixed sleeve 201 flows into the collecting bottle 208 through the guide tube 204. Part of the hydraulic fluid in the fixed sleeve 201 is diverted to the collecting bottle 208, which reduces the pressure of the hydraulic fluid flowing in the fixed sleeve 201, thereby preventing the pressure of the hydraulic fluid flowing in the three-valve group body 1 from being too high.

The hydraulic fluid flows into the three-valve group body 1 through the fixed sleeve 201. When the hydraulic fluid pressure in the pipeline increases, the pressure of the hydraulic fluid flowing in the fixed sleeve 201 on the regulating plate 202 exceeds the elastic force of the return spring 206 on the regulating plate 202. The regulating plate 202 moves downward under the action of the pressure difference on both sides. The downward-moving regulating plate 202 no longer blocks the guide pipe 204, and the hydraulic fluid in the fixed sleeve 201 is released. The hydraulic fluid flows into the collecting bottle 208 through the guide tube 204, and part of the hydraulic fluid in the fixed sleeve 201 is diverted into the collecting bottle 208, so that the pressure of the hydraulic fluid flowing in the fixed sleeve 201 is reduced, so that the pressure of the hydraulic fluid flowing in the three-valve group body 1 will not be too high. When the hydraulic fluid collected in the collecting bottle 208 is too much, the collecting bottle 208 is rotated, and the collecting bottle 208 drives the external threaded sleeve 207 to unscrew the fixed sleeve 201, thereby removing the collecting bottle 208 from the fixed sleeve 201, and cleaning the hydraulic fluid in the collecting bottle 208. After cleaning, the collecting bottle 208 is reinstalled in the fixed sleeve 201.
