AI Technical Summary
The existing self-closing angle valve lacks pressure relief devices when entering high-pressure water, causing high-pressure water to directly impact the internal structure of the valve, causing damage and affecting service life.
A new self-closing angle valve is designed, using a water-passing frame and buffer plate formed on the inner peripheral wall of the water inlet end. The buffer plate is equipped with a circumferential inlet groove and slide rod, the buffer cavity is equipped with a spring, and the buffer plate is placed on the buffer plate. There are conical cylinders that form water flow along the ring and through the water area to reduce pressure.
The service life of the self-closing angle valve is extended by reducing the pressure water flow.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of valves and relates to a self-closing angle valve, in particular to a new type of self-closing angle valve. Background Art
[0002] When high-pressure water enters the water inlet of the self-closing angle valve currently on the market, the lack of a pressure reducing device causes the high-pressure water to directly impact the internal structure of the valve. After a long period of action, the internal structure is damaged, affecting its use. Summary of the invention
[0003] The purpose of the utility model is to provide a new self-closing angle valve with a pressure reducing effect in view of the above problems existing in the prior art.
[0004] The purpose of the utility model can be achieved through the following technical solutions: a new type of self-closing angle valve, including a valve body with a water inlet end, characterized in that a water rack is integrally formed on the inner circumferential wall of the water inlet end and close to its port, the middle part of the water rack has a sleeve with a buffer cavity, and the sleeve is integrally connected to the water rack through a connecting plate, a water hole is formed between the two connecting plates, a buffer plate for high-pressure water impact is provided at the water inlet port, a plurality of circumferentially distributed water inlet grooves are provided on the buffer plate, a sliding rod slidably installed in the buffer cavity is provided on the bottom wall of the buffer plate, a spring is provided in the buffer cavity, and the buffer plate has a conical cylinder with a circumferential wall inclined inwardly.
[0005] In the above-mentioned novel self-closing angle valve, the water inlet port has a radially extending ring portion, and a water passing area is formed between the ring portion and the buffer plate.
[0006] In the above-mentioned novel self-closing angle valve, the water inlet groove is a fan-shaped structure.
[0007] Compared with the prior art, the new self-closing angle valve has the advantage of reducing the water flow pressure and thus increasing the service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0015] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the new self-closing angle valve comprises a valve body 2 with a water inlet end 1, a water passing frame 3 is integrally formed on the inner peripheral wall of the water inlet end 1 and near its port, a sleeve 4 with a buffer cavity is provided in the middle of the water passing frame 3, and the sleeve 4 is integrally connected with the water passing frame 3 through a connecting plate 13, a water passing hole 5 is formed between the two connecting plates 13, a buffer plate 6 for high-pressure water impact is provided at the water inlet port, a plurality of circumferentially distributed water inlet grooves 7 are provided on the buffer plate 6, a slide bar 8 slidably mounted in the buffer cavity is provided on the bottom wall of the buffer plate 6, a spring 9 is provided in the buffer cavity, both ends of the spring 9 are respectively fixedly connected to the slide bar 8 and the bottom wall of the buffer cavity by spring sheets, the buffer plate 6 is provided with a conical cylinder 10 with a peripheral wall inclined inwardly, when high-pressure water enters the water inlet end 1, it contacts the buffer plate 6, and drives the slide bar 8 on the buffer plate 6 along the internal pressure of the sleeve 4, plays a role in buffering the water flow, wherein part of the water enters the water inlet end 1 through the water inlet groove 7.
[0016] To further elaborate, the water inlet end 1 has a radially extending ring portion 11 at its port, and a water flow area 12 is formed between the ring portion 11 and the buffer plate 6. With the impact of high-pressure water, the size of the water flow area 12 between the ring portion 11 and the buffer plate 6 is adjusted, so another part of the water will enter the water inlet end 1 from the water flow area 12 and be buffered.
[0017] Preferably, the water inlet groove 7 is a fan-shaped structure.
[0018] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0019] Although the terms such as water inlet end 1, valve body 2, water passing frame 3, sleeve 4, water passing hole 5, buffer plate 6, water inlet groove 7, slide bar 8, spring 9, conical cylinder 10, ring portion 11, water passing area 12, connecting plate 13 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
