When the water outlet 16 is opened, the hot water enters the hot water channel of the valve body 1 from the hot water inlet pipe 34, and then the hot water enters the connecting sleeve 3 from the branch channel before mixing with the cold water, so that the hot water flows out from the outlet pipe 8; the inner wall of the groove 11 is fixed with a limiting column. One 17 and a limiting column two 18, the valve plate 15 is located between the limiting column one 17 and the limiting column two 18, and the limiting column one 17 and the limiting column two 18 can be used to limit the movement position of the valve plate 15, so that when the valve plate 15 rotates to two extreme positions, the water outlet 16 will be in a fully open or fully closed state respectively, thereby being able to achieve the water flow regulation flowing through the water outlet 16; the bottom end of the water outlet pipe one 8 is connected with a quick connector 9, and the quick connector 9 can be conveniently connected to the water inlet pipe of the fully automatic washing machine, and the bottom of the valve body 1 is provided with a table 32, and the bottom outer wall of the valve body 1 is fixed with a support plate 33, the support plate 33 is disc-shaped, and the valve body 1 is located at the center of the support plate 33, and the bottom of the support plate 33 is provided with a clamping assembly, which is used to clamp the valve The valve body 1 is fixed on the table 32; the clamping assembly includes two extrusion blocks 24, the bottom outer wall of the support plate 33 is provided with a slide groove 19, the inner sliding connection of the slide groove 19 is provided with a slider 20, the top of the extrusion block 24 is fixed with the slider 20, the top outer wall of the table 32 is provided with a mounting hole 21, the extrusion block 24 is located inside the mounting hole 21, the inner bearing of the slide groove 19 is connected with a screw 28, the slider 20 is connected with the screw 28 by a thread, when the screw 28 is rotated, the screw 28 can drive the slider 20 and the extrusion block 24 to move, when the two extrusion blocks 24 are in close contact with the inner wall of the mounting hole 21, the valve body 1 is fixed on the table 32; a bevel gear 29 is fixed to the outside of one end of the screw 28, the top outer wall bearing of the support plate 33 is connected to There is a rotating block 30, and the top outer wall of the rotating block 30 is provided with a hexagonal hole, and the hexagonal hole can be inserted with a hexagonal wrench, so that the rotating block 30 can be conveniently rotated by the wrench, and the connecting shaft of the rotating block 30 extends to the inside of the slide groove 19, and a bevel gear 2 31 is fixed thereon, and the bevel gear 1 29 and the bevel gear 2 31 are meshed, and the rotation of the rotating block 30 drives the bevel gear 2 31 to rotate, and the rotation of the bevel gear 2 31 drives the screw 28 to rotate; the top outer wall of the table 32 is provided with a matching groove 26, and the bottom outer wall of the support plate 33 is integrally formed with a matching block 27 adapted to the matching groove 26, and the matching block 27 is used to match the matching groove 26, so that the fixation of the valve body 1 can be limited, thereby facilitating the rapid determination of the installation direction of the valve body 1;A positioning column 25 is fixed to the outer wall of one side of the extrusion block 24, and a fixing block 22 is fixed to the outer wall of the bottom of the table 32. A positioning hole 23 is provided inside the fixing block 22, and the positioning column 25 is adapted to the positioning hole 23. When the faucet of the prior art is fixed on the table, a nut needs to be used to thread and fix it from the bottom of the table. Because the space below the table is narrow, it is extremely inconvenient to install and fix the faucet. By rotating the rotating block 30 on the support plate 33, the extrusion block 24 can be fixed inside the mounting hole 21 of the table 32 by the extrusion force, which not only solves the disadvantage of extremely inconvenient operation when installing and fixing from the table 32, but also, through the cooperation of the positioning column 25 and the positioning hole 23, the water valve will not shake after installation and fixing, thereby making the installation of the water valve more secure. ;
