Description

Technical Field

[0002] Patent No. CN205978484U discloses an angle valve. The structure of the utility model is reasonably designed, simple in structure and strong in practicability.

[0003] In the above-mentioned existing angle valve, the water outlet includes a second communication hole and a pressure reducing hole connected in sequence. The inner diameter of the pressure reducing hole is larger than that of the second communication hole. By setting the inner diameter of the pressure reducing hole to be relatively large, after the water comes out of the second communication hole and passes through the pressure reducing hole, the pressure is reduced, so that the flowing water is stable, effectively preventing the phenomenon that the water flowing out through the water outlet hole has a large pressure and splashes on the human body. However, the pressure reducing hole of this device can only reduce the pressure when the water flows out, and it is difficult to reduce the pressure inside the pipeline, and the practicability is relatively single.

[0004] In order to solve the above problems, the utility model provides an angle valve pressure reducing structure and an angle valve thereof. Content of the Utility Model

The inner diameter of the pressure reducing hole is larger than that of the second communication hole. By setting the inner diameter of the pressure reducing hole to be relatively large, after the water comes out of the second communication hole and passes through the pressure reducing hole, the pressure is reduced, so that the flowing water is stable, effectively preventing the phenomenon that the water flowing out through the water outlet hole has a large pressure and splashes on the human body. However, the pressure reducing hole of this device can only reduce the pressure when the water flows out, and it is difficult to reduce the pressure inside the pipeline, and the practicability is relatively single".

[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] Thus, a feature pointed out in this specification will be used to illustrate one of the features of one embodiment of the present utility model, rather than implying that each embodiment of the present utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features may be combined together to show possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0023] The principle and structure of the present utility model will be described in detail below in conjunction with the accompanying drawings and embodiments:

[0024] Refer to Figure 1-6 , a angle valve pressure reducing structure and its angle valve, including a water inlet pipe 1, the surface of the water inlet pipe 1 is threadedly connected with an angle valve body 2, the side of the angle valve body 2 is fixedly connected with a water outlet pipe 3, the inner wall of the angle valve body 2 is threadedly connected with a threaded sleeve 9, the top of the threaded sleeve 9 is fixedly connected with a rotating plate 6, a threaded hole is opened on the upper end surface of the rotating plate 6, a threaded rod 7 is threadedly connected in the threaded hole, the bottom end of the threaded rod 7 is fixedly connected with a pressing plate 8, a valve block 12 is slidably connected in the angle valve body 2, a spring 10 is fixedly connected to the upper end surface of the valve block 12, and the top end of the spring 10 is fixedly connected to the lower end surface of the rotating plate 6.

[0025] By providing the spring 10, when the pressure in the angle valve body 2 increases, the valve body will upwardly press the spring 10, so that the water outlet pipe 3 is communicated with the inside of the angle valve body 2 for automatic pressure relief.

[0026] Further, one end of the water outlet pipe 3 is communicated with the inside of the angle valve body 2, and a sealing ring 5 is fixedly connected to one end of the water outlet pipe 3.

[0027] By providing the sealing ring 5, when the water outlet pipe 3 is connected to other pipes, the sealing ring 5 can improve the sealing performance of the connection.

[0028] Further, a mounting sleeve 4 is slidably connected to the surface of the water outlet pipe 3, and the inner diameter of the mounting sleeve 4 matches the diameter of the water outlet pipe 3.

[0029] By providing the mounting sleeve 4, the mounting sleeve 4 can tightly mount other pipes on the water outlet pipe 3.

[0030] Further, a telescopic rod 11 is fixedly connected to the upper end surface of the valve block 12, and the top end of the telescopic rod 11 is fixedly connected to the lower end surface of the rotating plate 6.

[0031] By providing the telescopic rod 11, the telescopic rod 11 can prevent the valve block 12 from deflecting when moving.

[0032] Furthermore, the lower end surface of the abutting plate 8 abuts against the upper end surface of the valve block 12, and the size of the inner wall of the angle valve body 2 matches the size of the outer diameter of the water inlet pipe 1.

[0033] Furthermore, the number of telescopic rods 11 is set to four, and the size of the side surface of the valve block 12 matches the size of the inner wall of the angle valve body 2.

[0034] The working principle of the present utility model is as follows: First, the staff tightens the angle valve body 2 on the water inlet pipe 1. Then, the connecting pipe is installed on the water outlet pipe 3 through the installation sleeve 4. When it is necessary to open the pipe, the staff rotates the rotating plate 6 clockwise. The rotating plate 6 drives the threaded sleeve 9 to rotate inside the angle valve body 2. The rotating plate 6 can drive the angle valve body 2 to move upward through the telescopic rod 11, so that a gap appears between the water outlet pipe 3 and the angle valve body 2. At this time, the water flow can flow out through the gap. The staff only needs to adjust the number of turns of the rotation of the rotating plate 6 to achieve the adjustment of the water flow rate. When the pipe is closed, the staff can rotate the threaded rod 7 clockwise to drive the abutting plate 8 to move upward, so that the abutting plate 8 is separated from the valve block 12. When the pressure in the water inlet pipe 1 increases and exceeds the elastic force of the spring 10, the pressure in the water inlet pipe 1 can push the valve block 12 upward to make a gap appear between the angle valve body 2 and the water outlet pipe 3. At this time, automatic pressure relief can be achieved. When the pressure in the water inlet pipe 1 decreases, under the action of the self-elastic force of the spring 10, the valve block 12 can move downward to seal the water outlet pipe 3;

[0035] Compared with the prior art, the moving distance of the valve block 12 can be controlled, and the switch of the automatic pressure relief function can be realized, increasing the practicability.

[0036] The above is only the specific implementation manner of the present utility model, but 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 can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
