Description

Technical Field

[0001] The invention relates to the technical field of water inlet valves, and in particular to a novel side water inlet valve. Background Art

[0002] The toilet water inlet valve is a device used to control the automatic water inlet of the toilet water tank. When the water level in the water tank is lower than a certain level, the water inlet valve will flow into the water tank until the water level in the water tank rises to a certain level, and then the water inlet valve will stop the water. The water outlet of the traditional water inlet valve is in direct contact with the water in the water tank, which poses a risk of water backflow and causes the water in the water pipe to be contaminated. In addition, the traditional water inlet valve is equipped with a pressure storage chamber, which then divides one path directly to the water tank for water replenishment and another path to the buoy.

[0018] (4) In order to further ensure smooth water outflow, the present invention provides exhaust holes on the side wall of the main body to exhaust air in time, thereby preventing the air in the main body from being unable to be discharged in time when high-speed water flows down, causing congestion in the water outflow. In addition, a flow baffle cover is provided on the upper side of the main body to prevent the water from rushing down at high speed and hitting the water surface and then surging up when the water level is high, causing the water to splash everywhere.

The pressure relief pad 15 is installed on the lifting rod 2 and seals the pressure relief hole; the water stop cover 8 is provided with a mounting column extending to one side of the water stop rubber pad 14, and the water stop rubber pad 14 is inserted on the mounting column and there is a gap between the water stop rubber pad 14 and the mounting column to form a pressurization hole.

[0033] In this embodiment, in order to connect the water inlet pipe 10 with the main body 6 and form a water inlet channel of the water tank; the water inlet pipe 10 is installed on the water stop cover 8 through the nut cover 9, the water inlet channel 1001 is connected with the connecting flow channel 602 through the water stop port, and a sealing ring is provided between the water inlet pipe 10 and the nut cover 9.

[0035] Specific implementation process: water enters the side inlet valve from the water inlet pipe 10, passes through the filter assembly and the flow limiter 11 assembly, and since the pressure relief hole is in an open state, the pressure relief chamber composed of the water stop rubber pad 14 and the water stop cover 8 cannot maintain high pressure. The water stop rubber pad 14 is in an open state under the impact of the water flow in the water inlet pipe 10, and the water enters the connecting flow channel 602 through the water stop rubber pad 14 and then enters the inverted U-shaped flow channel 101. After the water comes out of the drainage piece 1, under its own gravity and potential energy, it flows to the buoy 5 as counterweight water through the counterweight channel 605, and directly enters the water tank in another way; water continues to enter the water tank, and the water level rises until the buoy 5 floats, and the buoy 5 and the adjusting screw 4 move up to drive the lifting rod 2 to lift up. The other end of the lifting rod 2 blocks the pressure relief hole under the action of the lever principle, and the water in the water inlet pipe 10 enters the pressure relief chamber from the pressurization hole. The pressure in the pressure relief chamber rises sharply, causing the water stop rubber pad 14 to press down and block the water stop port, thereby achieving a water stopping effect.
