detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, in order to make the present invention. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in FIG. 1 and FIG. 2, the water inlet valve with the muffling function according to the present invention includes a valve body 10 and a water stop valve 20, and a valve body 10 is provided with a back pressure chamber 11 in which the water stop valve 20 is disposed. The inlet body of the valve body 10; the valve body 10 has an inlet pipe 12 and an outlet pipe 14, the inlet pipe 12 is in communication with the water pipe, and the outlet pipe 14 is in communication with the water tank, and the water stop valve 20 is disposed in the inlet pipe 12 and the outlet pipe 14 Pick up. The water stop valve 20 is provided with a water stop rubber pad 22, The control of the water inlet and outlet water in the valve body 10 by the water stop valve 20 is known in the prior art and will not be described here. The water inlet valve of the present invention further includes a noise reduction device 30; in the water stop state, the water stop pad 22 abuts against the water stop surface 13 of the valve body 10 and seals the water passage to realize the inlet pipe 12 and the outlet pipe The barrier of 14; in the water-passing state, the water flow is reduced by the noise reduction device 30 in the valve body 10, and the water stop pad 22 of the water stop valve 20 is moved by the water pressure in the direction of the back pressure chamber 11 and passes through the water. The passage is opened, and the water flows into the outlet end to realize the communication between the inlet pipe 12 of the valve body 10 and the outlet pipe 14.

As shown in FIGS. 3, 4, and 5, the inner wall of the muffling device 30 of the present invention is a hollow over-water inner chamber 32, and the outer wall of the muffling device 30 has a spiral wall surface 34. A plurality of over-water tank holes 322 are provided in the wall surface of the water-passing inner chamber 32 of the noise damper device 30, and the water flow can stably pass through the water-passing water holes 322, thereby further reducing noise. In addition, a side of the sound absorbing device 30 opposite to the water stop valve 20 is provided with a boss 36. The boss 36 is provided with a filter 362 through which the water supply flows, and the water flows through the filter 362 and enters the back water chamber 11. Preventing impurities in the water flow from blocking the back pressure chamber 11 affects the performance of the back pressure chamber 11. Furthermore, one end of the water outlet pipe 14 is inserted into the water passing inner chamber 32 of the muffling device 30, and the outer diameter of the pipe wall portion of the water outlet pipe 14 inserted in the inner water chamber 32 is smaller than the outer water chamber 32. Inner diameter. Therefore, the water flows through the inner wall of the inner chamber 32, passes through the water stop valve 20, and flows to the outlet pipe 14.

The water inlet and water stopping process of the water inlet valve with the muffling function according to the present invention will be described below with reference to the accompanying drawings.

When the water level in the water tank (not shown) is lowered, the inlet valve needs to replenish the water tank. At this time, the water flows into the valve body 10 through the inlet pipe 12 of the valve body 10. Wherein, a part of the water flows through the filter 362 on the boss 36 of the muffling device 30 into the back pressure chamber 11, and most of the water flows through the spiral wall surface 34 surrounding the muffling device 30, and enters the water passing chamber of the muffling device 30. 32. Due to the presence of a plurality of over-water bath holes 322 in the inner chamber 32, the water flow passes through the water tank holes 322 stably. Since the water flow pressure is large, the back pressure chamber 11 is opened to release the pressure, the water stop valve 20 is opened, and the water flow enters the water outlet pipe 14 and finally flows to the water tank.

When the water tank is filled with water, the back pressure chamber 11 is closed, a part of the water flow enters the back pressure chamber, and the pressure of the back pressure chamber is gradually increased, and the water stop pad 22 abuts against the water stop surface 13 of the valve body 10, and the water is passed. The channel is sealed to achieve water stoppage of the inlet valve.
