Description

Technical Field

[0001] The utility model relates to a water inlet anti-splashing structure of a water inlet valve. Background Art

[0002] The horizontal float valve provided in the air cooler is used to open and close water to the inner cavity of the air cooler. In the prior art, when the water in the inner cavity of the air cooler decreases, the float swings downward with the liquid level, and the swing rod drives the float valve piston to move to a position away from the water outlet of the float water inlet valve, thereby opening the water outlet of the water inlet valve and replenishing water to the bottom of the inner cavity of the air cooler; under normal conditions, the replenished water flows downward through the water outlet of the water inlet valve and the vertical water outlet channel, but when the water inlet amount is relatively large and the pressure is relatively high, the vertical water outlet channel is relatively small and the water cannot be discharged quickly, which will cause the water to splash out from the side of the water inlet valve at the same time. Since a centrifugal fan is also provided in the inner cavity of the air cooler, the splashed water sprays to the centrifugal fan position, and even splashes to the air outlet of the centrifugal fan, causing abnormal operation. Utility Model Content

[0003] The utility model improves the above-mentioned problem, that is, the technical problem to be solved by the utility model is to provide a water inlet valve water splash-proof structure, which can effectively prevent water from splashing directly from the side of the water inlet valve to the centrifugal fan position inside the air cooler, thereby avoiding affecting the normal operation of the air cooler.

[0004] The utility model is constructed as follows: it includes a water inlet valve body and a water inlet and a water outlet arranged on the water inlet valve body; a vertical water outlet channel is arranged at the output end of the water outlet; a blocking slider which can be moved left and right and adjusted is arranged inside the right side of the water inlet valve body; a blocking piston is arranged on the side of the blocking slider close to the water outlet; the blocking slider is driven by a float swing mechanism; a splash-proof cover is installed outside the right side of the water inlet valve body; the splash-proof cover includes a cover body; an upper water baffle plate is extended downward from the upper right side of the cover body; and side water baffle plates are extended from the upper parts of the front and rear edges of the splash-proof cover to the middle thereof.

[0008] Furthermore, the first pendulum body, the water inlet valve body and the splash-proof cover are connected via a pin shaft, and a bayonet is provided on the outside of the pin shaft.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the device has a simple structure, reasonable design and is easy to use.

[0018] Example: Figures 1 to 7 As shown, in the present embodiment, there is provided a water inlet valve water splash-proof structure, comprising a water inlet valve body 1 and a water inlet 101 and a water outlet 102 arranged on the water inlet valve body, a vertical water outlet channel 103 is arranged at the output end of the water outlet, a blocking slider 2 which can be moved left and right and adjusted is arranged inside the right side of the water inlet valve body, a blocking piston 3 is arranged on the side of the blocking slider close to the water outlet, the blocking piston can be a rubber plug, the blocking slider is driven by a float swing mechanism 4, a splash-proof cover 5 is installed on the outside of the right side of the water inlet valve body, the splash-proof cover comprises a cover body 501, an upper water baffle 502 extends downward from the upper right side of the cover body, and side water baffles 503 extend from the upper part of the front and rear edges of the splash-proof cover to the middle thereof.

[0019] When the water inlet valve is replenishing water: part of the water flows downward from the water inlet on the water inlet valve body and the vertical water outlet channel to the bottom of the inner cavity of the chiller, and the other part of the water splashes to the side from the gap between the water inlet valve body and the blocking slider. By inserting a splash-proof cover on the outside of the water inlet valve, the splashing water is blocked by the upper water baffle plate and two side water baffle plates to prevent the water from splashing to the outside to the centrifuge. After being blocked by the upper water baffle plate and the side water baffle plate, the splashing water flows downward along the upper water baffle plate and the side water baffle plate, thereby preventing the centrifugal fan from being affected by the splashing water and causing abnormal operation of the chiller.

[0020] In the embodiment of the utility model, the cross section of the cover body is U-shaped, and the front and rear edges of the lower side of the cover body are provided with folded edges 504 facing inwards.

[0021] In the embodiment of the utility model, the float swing mechanism 4 includes a first pendulum body 401, a second pendulum body 402 and a hand screw 403, an oblique push block 404 is arranged above one side of the first pendulum body, a limiting groove 201 is arranged in the middle of the blocking slider, and the oblique push block is located in the limiting groove, a first toothed end face 405 is arranged in front of the other side of the first pendulum body, and a second toothed end face 406 is arranged behind the side of the second pendulum body close to the first pendulum body, the first toothed end face is combined with the second toothed end face and meshes with each other, the hand screw passes through the connection between the first pendulum body and the second pendulum body, a threaded rod 407 is arranged below the side of the second pendulum body away from the first pendulum body, a float 408 is arranged on the threaded rod, and the float is threadedly connected to the threaded rod.

[0022] When the height of the float needs to be adjusted, there are two ways: first, by directly adjusting the height position of the float on the threaded rod, this is fine adjustment; second, by loosening the hand screw, the first toothed end face and the second toothed end face are rotated relative to each other to adjust the height of the float, and finally tightening the hand screw, this is coarse adjustment.

[0023] In the embodiment of the utility model, slide rails 104 are arranged at the front and rear of the right inner cavity of the water inlet valve body, and slide grooves 202 for matching with the slide rails are arranged at the front and rear of the blocking slider.

[0025] A sleeve 409 is provided on one side of the first pendulum body for passing a pin shaft, and the sleeve and the pin shaft are rotatably matched.

[0026] In the embodiment of the utility model, the working principle of the water inlet valve is as follows: by setting the water inlet valve at the bottom of the inner cavity of the air cooler, the water level inside the air cooler can be controlled; when the water level inside drops, the float moves downward with the liquid level, driving the first pendulum body and the second pendulum body to swing downward, pushing the blocking slider to move, and the blocking piston of the blocking slider leaves the water outlet, at which time water is replenished from the water inlet of the water inlet valve; when the water level is replenished to a certain high level, the float moves upward with the liquid level, driving the first pendulum body and the second pendulum body to swing downward, pushing the blocking slider to move, and the blocking piston of the blocking slider closes the water outlet, so that water can no longer flow in. Therefore, the utility model has a simple structure and a reasonable design, which is conducive to achieving stable and reliable liquid level control.
