Description

Technical Field

[0001] The utility model relates to a water outlet silent drainage structure of a water inlet valve. Background Art

[0002] When the existing water inlet valve is not provided with a valve drainage structure, water flows directly downward. For example, most of the existing water inlet valves include a water stop cup and a floating bucket. Before the water inlet valve stops water, the water stop cup does not allow water from the valve to enter the water stop cup. If water enters the water stop cup in advance, the water inlet valve will stop water in advance before reaching the working water level, causing the toilet water level to be unstable, seriously affecting the flushing function of the toilet. In order to solve this problem, CN212248550U discloses a water outlet drainage structure of a water inlet valve, which is provided with a diverter. The diverter adopts two C-shaped diversion grooves extending along the circumferential direction and two diversion channels extending along the longitudinal direction. The water inlet valve has the advantages of compact overall structure, no space occupation, stable structure and good integrity. However, its water flow is strip-shaped drainage, which produces a large noise problem. Summary of the invention

[0004] The purpose of the utility model is achieved in this way. A water outlet silent drainage structure of a water inlet valve, the water inlet valve comprises a water inlet valve body, a float assembly, a water stop assembly and a diverter, the water stop assembly is arranged on the back pressure cover of the back pressure part of the water inlet valve body; the float assembly comprises a water stop cup and a float barrel, the float barrel floats up or down with the water level of the water stop cup, and the water stop assembly opens or closes the valve on the back pressure cover by the action of the float barrel; the water stop cup is connected to the water inlet valve body through its guide column, the diverter is sleeved on the outside of the guide column of the water stop cup, the diverter is provided with a water receiving tray and a water outlet hole at the end of the water receiving tray, the water receiving tray corresponds to the valve position on the back pressure cover, so that the received water flows through the water outlet hole and is drained along the guide wall extending downward from the end of the water receiving tray, forming a thin sheet water outlet silent drainage structure.

[0005] In the utility model, a transverse flow guide baffle is arranged on the flow guide wall, and the transverse flow guide baffle makes the water flow change direction, release pressure and flow slowly down along the flow guide wall.

[0006] The utility model provides a transverse flow guide baffle with a transverse slope and a longitudinal slope to form a double-slope flow guide.

[0007] The utility model has a longitudinal guide baffle plate on the guide wall, which can change the direction of water flow, release pressure and slowly flow down along the guide wall.

[0008] The utility model provides a guide column of a water stop cup with a vertical rib for positioning the flow guider, which is positioned so that the water receiving tray corresponds to the valve position on the back pressure cover and is fixed and does not move, and the size of the vertical rib matches the positioning groove of the flow guider sleeve.

[0009] The utility model has convex ribs on the outer side of the guide wall, and the convex ribs are in tight contact with the inner wall of the water stop cup, so that the guide wall is easy to insert and has a stable structure.

[0010] The utility model has the advantages that, firstly, the water receiving tray receives water in a thin sheet-like manner, and secondly, the received water flows through the water outlet hole and is drained into a thin sheet along the guide wall extending downwardly from the end of the water receiving tray, so that the water outlet and drainage are silent; further, the guide baffle plate reverses the water flow and releases the pressure, so that the water flows slowly downward along the guide wall, so that the water flow noise is further reduced, and the best effect of silent water outlet and drainage is achieved.

Implementation

[0022] Reference Figures 1 to 9 The present embodiment is a silent drainage structure for water outlet of an inlet valve. The inlet valve comprises an inlet valve body 1, a float assembly, a water stop assembly 2 and a flow diverter 3. The water stop assembly is arranged on a back pressure cover 4 of the back pressure part of the inlet valve body; the float assembly comprises a water stop cup 5 and a float barrel 6. The float barrel rises or falls with the water level of the water stop cup, and the water stop assembly opens or closes the valve on the back pressure cover by the action of the float barrel; the water stop cup is connected to the inlet valve body through its guide column 7, and the flow diverter is arranged on the outer side of the guide column of the water stop cup. The flow diverter is provided with a water receiving tray 8 and a water outlet hole 9 at the end of the water receiving tray. The water receiving tray corresponds to the valve position on the back pressure cover, so that the received water flows through the water outlet hole and is drained along the flow guide wall 10 extending downward from the end of the water receiving tray, forming Thin sheet water outlet silent drainage structure; the guide wall is provided with a transverse guide baffle 11, which makes the water flow reverse, release pressure and slowly flow down along the guide wall; the transverse guide baffle has a transverse slope a and a longitudinal slope b to form a double slope drainage; the guide wall is provided with a longitudinal guide baffle 12, which makes the water flow reverse, release pressure and slowly flow down along the guide wall; the guide column of the water stop cup is provided with a vertical rib 13 for positioning the diverter, which is positioned so that the position of the water receiving tray corresponds to the valve position on the back pressure cover and is fixed and does not move, and the size of the vertical rib matches the positioning groove 14 of the diverter sleeve; a convex rib 15 is provided on the outside of the guide wall, and the convex rib is in tension contact with the inner wall of the water stop cup, forming a structure in which the guide wall is easy to insert and the guide wall is stable.

[0023] The working process of the utility model is as follows: Figure 1 , Figures 3 to 9 As shown, when the water stop assembly is in the open state, the water flowing out of the valve flows to the water receiving tray. The water flowing in the water receiving tray is in the form of a thin sheet, and the received water flows out through the water outlet. In the vertical direction, the horizontal guide baffle just blocks the water outlet, and the water flowing out of the water outlet is blocked, and the water flow is reversed and the pressure is released, so that the water flows slowly downward along the guide wall. In this way, the water flow noise is further reduced, and the best effect of silent water outlet and diversion is achieved.
