[0034] The utility model provides a water valve with sealing ring, in order to make the purpose, technical scheme and effect of the utility model more clear, explicit, the following refers to the drawing and raises example to make further detailed description to the utility model.

[0035] In the description of the utility model, it is understood that the orientation or positional relation indicated by the terms "up and down, left and right" and the like is based on the orientation or positional relation shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and cannot be understood as a limitation on the utility model; in addition, the terms "mounting", "connecting" and the like should be understood in a broad sense, and for ordinary skilled persons in the art, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0036] Please refer to Figures 1 to 5 The utility model provides a water valve with sealing ring, including valve body 1, air inlet nozzle 2, valve core 3, reset spring 4, step part 5, water inlet nozzle 6, water outlet nozzle 7 and sealing ring 8, the upper portion of valve body 1 is set up with air inlet nozzle 2, the lower portion of valve body 1 is arranged from top to bottom with water outlet nozzle 7 and water inlet nozzle 6, a accommodating cavity 9 is set up in valve body 1, and valve core 3 is movably arranged in the accommodating cavity 9, air inlet nozzle 2, water inlet nozzle 6 and water outlet nozzle 7 are all communicated with accommodating cavity 9, the inner wall of valve body 1 is provided with step part 5, valve core 3 includes valve seat 10, valve rod 11 and valve head 12 connected in sequence, reset spring 4 is sleeved on valve rod 11 and compressed between valve seat 10 and step part 5, valve head 12 is located between water inlet nozzle 6 and water outlet nozzle 7 for adjusting the opening and closing of water inlet nozzle 6, air inlet nozzle 2 is located at the upper end of valve seat 10, valve seat 10 is also sleeved with sealing ring 8, and sealing ring 8 is compressed between valve seat 10 and the inner wall of accommodating cavity 9.

[0037] The specific working principle of the water valve with a sealing ring in this embodiment is as follows: when the water valve is in a closed state, the reset spring 4 compresses the valve seat 10 tightly at the top of the accommodating cavity 9, and at the same time, the sealing ring 8 is also tightly pressed between the valve seat 10 and the inner wall of the accommodating cavity 9, forming a good seal. In addition, the air inlet nozzle 2 is located at the upper end of the valve seat 10, which can be used to charge air into the accommodating cavity 9 when needed, helping to adjust the water level or perform other operations. When it is needed to open the water valve, the external control device drives the valve core 3 to move downward through the air inlet nozzle 2, and the valve head 12 is lifted, thereby opening the passage between the water inlet nozzle 6 and the water outlet nozzle 7, allowing water to flow from the water inlet nozzle 6 to the water outlet nozzle 7 through the accommodating cavity 9. At this time, due to the movement of the valve core 3, the reset spring 4 is further compressed, but still maintains a certain elastic force to support the position of the valve core 3. When the external control device stops acting, the elastic force of the reset spring 4 pushes the valve core 3 to move upward, and the valve head 12 is pressed tightly on the water inlet nozzle 6 again, closing the water flow passage. In this process, the sealing ring 8 continues to play its sealing role, ensuring the close fit between the valve seat 10 and the inner wall of the accommodating cavity 9, preventing water leakage.

[0038] Please refer to Figure 1 and Figure 2 , the number of the air inlet nozzles 2 is two, and the two air inlet nozzles 2 are arranged side by side on the side of the accommodating cavity 9, and the water inlet nozzle 6 and the water outlet nozzle 7 are arranged in pairs side by side. The provision of two air inlet nozzles 2 can provide better air flow control and adjustment capability, which is helpful to charge air or exhaust air into the accommodating cavity 9 when needed, thereby achieving more accurate water level control or other operations; the side-by-side arrangement of the water inlet nozzle 6 and the water outlet nozzle 7 makes the water flow distribution more uniform, which helps to reduce turbulence and pressure loss.

[0039] In the embodiment, a core nut 13 for cutting off the passage between the water inlet nozzle 6 and the water outlet nozzle 7 is further included, the core nut 13 is fixed on the valve head 12, and the diameter of the core nut 13 is greater than the diameter of the valve rod 11. A water flow passage is arranged in the accommodating cavity 9, two ends of the water flow passage are respectively provided with the water inlet nozzle 6 and the water outlet nozzle 7, and the core nut 13 is movably arranged at the end of the water flow passage close to the water inlet nozzle. It can be understood that the core nut 13 can restore or cut off the communication passage between the water inlet nozzle 6 and the water outlet nozzle 7 through simple extension and retraction operation under the action of air blowing or air exhausting control of the valve core 3 at the air inlet nozzle 2, thereby providing a simple and reliable switching mechanism, and the larger diameter of the core nut 13 can be completely blocked in the water flow passage, ensuring the stability and durability thereof during operation.

[0040] Optionally, the valve body 1 comprises a valve upper body 14 and a valve lower body 15 spliced together, and the stepped portion 5 is located on the top surface of the valve lower body 15. The valve body 1 adopts the design of splicing together from top to bottom, which is convenient for manufacturing and assembling, and the stepped portion 5 is arranged on the top surface of the valve lower body 15, which is helpful for positioning and fixing the valve core 3 and ensures the stability of the valve core 3 during operation. Preferably, the water flow channel is arranged in the valve lower body 15. The water flow channel is directly arranged in the valve lower body 15, which simplifies the internal structure and reduces potential leakage points.

[0041] Optionally, an annular clamping groove is arranged on the valve seat 10, and a sealing ring 8 is sleeved in the annular clamping groove. That is, the design of the annular clamping groove enables the sealing ring 8 to be more stably fixed on the valve seat 10, reducing the risk of displacement or falling of the sealing ring 8 during use. In addition, the sealing ring 8 is a rubber sealing element or a silica gel sealing element. Rubber or silica gel is selected as the sealing material, which has good elasticity and durability and can maintain stable sealing performance under various working conditions. Preferably, the sealing ring 8 is a rubber sealing element, which has good oil resistance, wear resistance, aging resistance and air tightness.

[0042] In the embodiment, a valve fixing plate 16 is further included, the lower part of the valve body 1 is fixedly connected with the valve fixing plate 16, and a fixing hole is arranged on the valve fixing plate 16. Optionally, the fixing hole is a threaded hole. The valve fixing plate 16 provides additional stability and support, ensuring that the water valve is not easy to shake or displace during installation and use. The arrangement of the fixing hole enables the water valve to be fixed firmly at the required position, facilitating installation and maintenance.

[0043] In summary, the water valve with a sealing ring of the utility model, the reset spring 4 compresses the valve seat 10 tightly on the top of the accommodating cavity 9 through compression force, and at the same time, the sealing ring 8 is also tightly pressed between the valve seat 10 and the inner wall of the accommodating cavity 9, forming good sealing. Good sealing enables the inflation or deflation of the air inlet nozzle 2 to accurately control the movement of the valve core 3. Compared with the traditional water valve sealed by a diaphragm, the water valve with a sealing ring can better prevent leakage and improve the service life. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
