Description

Technical Field

[0001] The utility model relates to the field of water valves, and more specifically, to a high-precision water valve sheet. Background Technique

[0002] The water valve sheet is a relatively key component in a faucet.

[0003] However, in the prior art, most of the water valve sheets are used to control the size of the water flow, and it is impossible to adjust the temperature of the water discharged from the faucet by controlling the ratio between hot water and cold water, resulting in the water discharged from the faucet having only a single temperature, which is inconvenient in cold weather and has limitations in use.

[0004] Therefore, a high-precision water valve sheet is proposed for the above problems. Content of the Utility Model

[0005] 1. Technical Problems to be Solved

[0006] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a high-precision water valve sheet to solve the problems put forward in the above background technique.

[0007] 2. Technical Solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] A high-precision water valve sheet includes a water pipe. A telescopic rod is fixedly connected inside the water pipe. A spring is sleeved on the outer wall of the telescopic rod. The output end of the telescopic rod is fixedly connected with a baffle. The baffle is located inside the water pipe. A limiting block is fixedly connected inside the water pipe. Chamfers are provided on one side of both the baffle and the limiting block, and the chamfer angles provided on the baffle are the same as those provided on the limiting block.

[0010] Furthermore, a lower valve sheet is fixedly connected to the end of the water pipe.

[0011] Furthermore, the lower valve sheet is provided with a water outlet hole, a hot water hole and a cold water hole.

[0012] Furthermore, the diameter of the water outlet hole is larger than that of the hot water hole.

[0013] Furthermore, the diameters of the hot water hole and the cold water hole are equal.

[0014] Furthermore, an upper valve sheet is attached to the side of the lower valve sheet away from the water pipe, and the upper valve sheet is provided with a water droplet groove.

[0015] 3. Beneficial Effects

[0016] Compared with the prior art, the advantages of the utility model are as follows:

[0017] (1) In this solution, the staff can rotate the handle above the water valve to drive the upper valve plate to swing above the lower valve plate. As the rotation direction of the upper valve plate is different, the water droplet groove opened on the upper valve plate is always connected to the water outlet hole. When the upper valve plate completely covers the cold water hole, the hot water hole and the water droplet groove are connected. At this time, the proportion of hot water in the water is relatively high, enabling the staff to release water with a relatively high temperature from the water valve. If the upper valve plate completely covers the hot water hole and the cold water hole is connected to the water droplet groove, the proportion of cold water in the water pipe is relatively high, enabling the staff to release water with a relatively low temperature from the water valve.

[0018] (2) In this solution, when the water in the water pipe stops flowing, if the water in the water pipe flows back, the flowing-back water will impact the baffle and cause the telescopic rod to stretch. As the baffle gradually moves towards the direction where the limit block is located, one side of the baffle will fit against one side of the limit block, thereby completing the blocking of the water pipe to achieve the purpose of preventing water from flowing back.

[0028] Embodiment:

[0029] Please refer to Figures 1-4 , a high-precision water valve sheet, including a water pipe 1. An expansion rod 12 is fixedly connected inside the water pipe 1. A spring 13 is sleeved on the outer wall of the expansion rod 12. The output end of the expansion rod 12 is fixedly connected with a baffle 2. The baffle 2 is located inside the water pipe 1. A limiting block 11 is fixedly connected inside the water pipe 1. Chamfers are provided on one side of both the baffle 2 and the limiting block 11, and the chamfer angles provided on the baffle 2 and the limiting block 11 are the same. In this solution, the water flow direction inside the water pipe 1 is from the upper valve sheet 18 to the baffle 2. When the water flows normally in the water pipe 1, it will squeeze one side of the baffle 2. After being squeezed, the length of the expansion rod 12 will shorten. During this process, the spring 13 will undergo elastic deformation and contract to store a certain amount of elastic potential energy due to the shortening of the expansion rod 12. If the water in the water pipe 1 flows reversely, the reverse-flowing water will impact the side of the baffle 2 away from the limiting block 11. At this time, the expansion rod 12 will elongate, and the spring 13 will also stretch. As the expansion rod 12 continuously elongates, one side of the baffle 2 will fit with one side of the limiting block 11. At this time, the inside of the water pipe 1 is blocked, thereby achieving the purpose of preventing reverse flow.

[0030] Please refer to Figures 1-4 , the end of the water pipe 1 is fixedly connected with a lower valve sheet 14. In this solution, the lower valve sheet 14 is used for the water flow to pass through.

[0031] Please refer to Figures 1-4, the lower valve plate 14 is provided with a water outlet hole 15, a hot water hole 16 and a cold water hole 17. In this solution, by mixing hot water and cold water in different proportions with the water passing through the water outlet hole 15, the purpose of adjusting the temperature of the water is achieved.

[0032] Please refer to Figures 1-4 , the diameter of the water outlet hole 15 is larger than the diameter of the hot water hole 16 to facilitate the mixing of hot water and the water passing through the water outlet hole 15.

[0033] Please refer to Figures 1-4 , the diameter of the hot water hole 16 is equal to the diameter of the cold water hole 17 to facilitate the mixing of cold water and the water passing through the water outlet hole 15.

[0034] Please refer to Figures 1-4 , a upper valve plate 18 is attached to the side of the lower valve plate 14 away from the water pipe 1. The upper valve plate 18 is provided with a water droplet groove 19. In this solution, the staff can rotate the handle above the water valve to drive the upper valve plate 18 to swing above the lower valve plate 14. As the rotation direction of the upper valve plate 18 is different, the water droplet groove 19 opened on the upper valve plate 18 is always communicated with the water outlet hole 15. When the upper valve plate 18 completely covers the cold water hole 17, the hot water hole 16 and the water droplet groove 19 are communicated. At this time, the proportion of hot water in the water is relatively high, so that the staff can release water with a higher temperature from the water valve. If the upper valve plate 18 completely covers the hot water hole 16 and the cold water hole 17 and the water droplet groove 19 are communicated, the proportion of cold water in the water pipe 1 is relatively high, so that the staff can release water with a lower temperature from the water valve.

[0035] Working principle: The staff can rotate the handle above the water valve to drive the upper valve plate 18 to swing above the lower valve plate 14. As the rotation direction of the upper valve plate 18 is different, the water droplet groove 19 opened on the upper valve plate 18 is always communicated with the water outlet hole 15. When the upper valve plate 18 completely covers the cold water hole 17, the hot water hole 16 and the water droplet groove 19 are communicated. At this time, the proportion of hot water in the water is relatively high, so that the staff can release water with a higher temperature from the water valve. If the upper valve plate 18 completely covers the hot water hole 16 and the cold water hole 17 and the water droplet groove 19 are communicated, the proportion of cold water in the water pipe 1 is relatively high, so that the staff can release water with a lower temperature from the water valve. In addition, the water flow direction in the water pipe 1 is from the upper valve plate 18 to the baffle 2. When the water flows in the water pipe 1 constantly, it will squeeze one side of the baffle 2. After being squeezed, the length of the telescopic rod 12 will shorten. During this process, the spring 13 will undergo elastic deformation and contract and store a certain amount of elastic potential energy due to the shortening of the telescopic rod 12. If the water in the water pipe 1 flows backward, the backward flowing water will impact the side of the baffle 2 away from the limit block 11. At this time, the telescopic rod 12 will elongate and the spring 13 will also stretch. As the telescopic rod 12 continuously elongates, one side of the baffle 2 will fit with one side of the limit block 11. At this time, the internal blockage of the water pipe 1 is completed, so as to achieve the purpose of preventing backflow.

[0036] The above are only the preferred specific embodiments of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and its improved concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
