Description

Technical Field

[0001] The utility model relates to the technical field of water valves, in particular to a floating ball water valve structure. Background Art

[0002] There is a kind of float water valve, which includes a housing and a float. The housing is provided with a water inlet and a water outlet, a valve core is provided in the housing, and a sealing ring is provided on the valve core. The float is connected to the valve core by transmission. The float can control the movement of the valve core in the housing according to the height of the water level to open or close the water inlet and control the water flow.

[0003] When using this type of float water valve, the water outlet will be aimed at the container, and there is generally no obstruction between the water outlet and the container. In actual production work, this type of float water valve is needed to provide a larger water flow rate to meet production needs. However, when the water flow rate is large, it is easy to cause large fluctuations in the water surface in the container. If the water surface fluctuates greatly, causing the float to rise suddenly, the valve core may quickly approach the water inlet, closing the water inlet in a short time, resulting in a "water hammer effect". The impact force of the water hammer effect on the valve body can reach several times or even dozens of times the impact force of the water flow, which can easily impact the sealing ring on the valve body to deform, shift, etc., causing the valve body to be unable to close the water inlet or unable to open the water inlet, resulting in a failure of the float water valve.

[0025] like Figures 1 to 5 As shown, a float water valve structure includes a shell 1 and a float 2, the shell 1 is provided with a water inlet 11 and a water outlet 12, the shell 1 is provided with a valve core 5, the valve core 5 is provided with a sealing ring 53, the float 2 is transmission-connected with the valve core 5, the float 2 can drive the valve core 5 to move in the shell 1 to open or close the water inlet 11; it also includes a water outlet buffer structure 3, the water outlet buffer structure 3 is provided with a cavity 34 inside, the cavity 34 is connected with the water outlet 12, the water outlet buffer structure 3 is also provided with a water outlet hole 33, the water outlet hole 33 is connected with the cavity 34 and the external space of the water outlet buffer structure 3, so that the water flowing out of the water outlet 12 at least partially collides with the inner wall of the cavity 34, and then leaves the cavity 34 from the water outlet hole 33.

[0026] When the float water valve structure is opened, the water flows out from the water outlet 12, and then collides with the inner wall of the cavity 34, so that the kinetic energy of the water is reduced. After the water flows out from the water outlet 12, it is blocked by the inner wall of the cavity 34, and then flows out from the water outlet 12 into the container. When the water flows to the water surface in the container, the kinetic energy of the water flow is reduced due to the collision with the inner wall of the cavity 34, and the water outlet 33 can also play the role of reducing the cross-section of the water flow, and the impact force of the water flow on the water in the container is reduced, which is not easy to cause too much fluctuation of the water surface in the container, and will not drive the position of the float 2 to rise suddenly, avoiding the situation that the valve body suddenly closes the water inlet 11, which is conducive to reducing the possibility of deformation and displacement of the sealing ring 53 due to the sudden closure of the water inlet 11, and is conducive to reducing the maintenance frequency of the float 2 water valve, extending the service life of the float 2 water valve, and ensuring smooth production.

[0027] In some specific embodiments, reference Figure 1 and Figure 2 The water outlet buffer structure 3 includes a bottom plate 31 and a side plate 32 . The bottom plate 31 and the side plate 32 enclose a cavity 34 . The bottom plate 31 faces the water outlet 12 .

[0028] Specifically, the water inlet 11 is located at one end of the housing 1, and the water outlet 12 is located at the lower side of the housing 1. When in use, the water outlet 12 is generally facing downward. The bottom plate 31 of the water outlet buffer structure 3 is placed directly opposite the water outlet 12, which can effectively reduce the kinetic energy and speed of the water flow and achieve a buffering effect.

[0029] In some specific embodiments, reference Figure 1 and Figure 2 The water outlet 33 is provided on the bottom plate 31 and / or the side plate 32 .

[0030] Specifically, multiple water outlet holes 33 are all provided on the side plate 32, and no water outlet hole 33 is provided on the bottom plate 31. After the water flow directly collides with the bottom plate 31, the kinetic energy is greatly reduced, and then it flows out from the water outlet holes 33 on the side plate 32. Such a configuration can further improve the effect of "reducing the kinetic energy and speed of water flow", improve the buffering effect, and better protect the sealing ring 53.

[0031] In some other embodiments, water outlet holes 33 are provided on both the side plate 32 and the bottom plate 31 .

[0032] In some other embodiments, the bottom plate 31 is provided with a water outlet hole 33 , while the side plate 32 is not provided with a water outlet hole 33 .

[0033] In some specific embodiments, reference Figure 1 The float water valve structure also includes a water outlet pipe 4, and two ends of the water outlet pipe 4 are respectively connected to the water outlet 12 and the water outlet buffer structure 3.

[0034] Specifically, a water outlet is formed on the housing 1, and the water outlet 12 is arranged inside the water outlet. The upper end of the water outlet pipe 4 is sleeved on the water outlet, and the water outlet pipe 4 and the water outlet are fixed with screws to prevent the water outlet buffer structure 3 from being separated from the housing 1 due to the impact of the water flow when the water is discharged. The lower end of the water outlet pipe 4 is fixedly connected to the water outlet buffer structure 3, and the interior thereof is communicated with the cavity 34 of the water outlet buffer structure 3, and the water flowing out of the water outlet 12 passes through the water outlet pipe 4 and enters the cavity 34 of the water outlet buffer structure 3.

[0035] In some specific embodiments, reference Figure 1 and Figure 2 The outer contour of the water outlet buffer structure 3 is cylindrical, and the water outlet holes 33 are evenly distributed on the side plates 32 of the water outlet buffer structure 3 in the circumferential direction.

[0036] A plurality of water outlet holes 33 are arranged on the side plate 32 of the water outlet buffer structure 3. The water flow with a larger cross-section flowing out from the water outlet 12 is dispersed to each water outlet hole 33 to form a plurality of water flows with smaller cross-sections. The water outlet buffer structure 3 can achieve a large water output while having a better buffering effect and not causing too much fluctuation of the water surface in the container, thereby ensuring smooth production.

[0037] The water outlet buffer structure 3 is arranged in a cylindrical shape, and the water outlet 12 is arranged on the circumferential side plate 32 thereof, so that the water temporarily stored in the cavity 34 can flow out from the water outlet buffer structure 3 in a timely and uniform manner, thereby avoiding excessive accumulation of water and accumulation of water in a certain part of the cavity 34.

[0038] Furthermore, the cavity 34 of the water outlet buffer structure 3 has a large volume, and the water in the cavity 34 can be discharged from the water outlet 12 in time, which can avoid the cavity 34 being filled with water due to insufficient drainage, causing the water flow to damage the pipeline or even the water pump.

[0039] In some specific embodiments, reference Figure 3 and Figure 4 A valve core 5 moving channel 13 connecting the water inlet 11 and the water outlet 12 is provided on the inner side of the shell 1, a limiting ring 131 is provided on the inner side of the valve core 5 moving channel 13, the valve core 5 includes a core shaft and a clamping ring 51 provided at one end of the core shaft close to the water inlet 11, a first sealing ring 511 is provided on the clamping ring 51, the clamping ring 51 can be clamped on the limiting ring 131 and squeeze the first sealing ring 511 on the limiting ring 131, and the sealing ring 53 includes the first sealing ring 511.

[0040] When the water level in the container rises, the float 2 rises, and the valve core 5 moves toward the water inlet 11 until the first clamping ring 51 squeezes the first sealing ring 511 onto the limit ring 131 to close the water inlet 11; when the water level in the container drops, the float 2 drops, and the valve core 5 moves away from the water inlet 11, and water can enter the valve core 5 moving channel 13 from the water inlet 11 and flow out from the water outlet 12.

[0041] In some specific embodiments, reference Figures 3 to 5 A second sealing ring 52 is also provided on the end of the valve core 5 away from the water inlet 11, and the outer peripheral side of the second sealing ring 52 abuts against the inner wall of the valve core 5 moving channel 13. The water inlet 11, the first sealing ring 511 and the second sealing ring 52 are arranged in sequence along the valve core 5 moving channel 13, and the water outlet 12 is located between the first sealing ring 511 and the second sealing ring 52.

[0042] The second sealing ring 52 extends from the inside to the outside in the direction from close to far away from the water inlet 11, and is in a trumpet shape as a whole. When the water inlet 11 is in an open state, the second sealing ring 52 can block the water flow and limit the water flow away from the water outlet 12, so that the water flow can flow out of the water outlet 12 more smoothly; when the valve core 5 moves away from the water inlet 11, the second sealing ring 52 can slow down the movement speed of the valve core 5, so as to avoid the impact force of the water flow rushing into the moving channel 13 of the valve core 5 after the water inlet 11 is suddenly opened, causing damage to the float water valve structure.

[0043] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
