Description

Technical Field

[0001] This utility model relates to the field of valve core technology, specifically a streamlined valve core structure that prevents particle accumulation. Background Technology

[0002] In industries such as petrochemicals, natural gas extraction, power generation, food processing, pharmaceuticals, and environmental water treatment, valves are core control components of fluid transport systems (such as pipelines, reactors, and storage tanks). Their function is to control the flow direction, pressure, and flow rate of fluids by opening, closing, or adjusting the position of the valve core. However, traditional valve core structures are prone to particle accumulation due to design flaws, leading to valve jamming, leakage, reduced control accuracy, or even failure, seriously affecting production safety and efficiency.

[0003] However, when transporting liquids containing particles, existing valve cores are prone to particle accumulation in corners and dead angles due to design flaws, which prevents the liquid from flowing properly. This leads to valve jamming, leakage, reduced control accuracy, or even failure, seriously affecting production safety and efficiency.

[0004] Therefore, a streamlined valve core structure to prevent particle accumulation is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a streamlined valve core structure that prevents particle accumulation. This solves the problem that existing valve cores, when conveying liquids containing particles, are prone to particle accumulation at corners and dead angles due to design flaws. This results in a lack of liquid guidance, leading to valve jamming, leakage, reduced control accuracy, or even failure, seriously affecting production safety and efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a valve core housing, which includes an inlet and an outlet. An arc-shaped protrusion is fixedly connected inside the valve core housing. A connecting mechanism is provided inside the valve core housing. The connecting mechanism includes a guide groove, a sliding column, a limiting block, an annular groove, a sealing ring, and a flow guiding surface.

The annular groove is located on the outer side of the sliding column. The sealing ring is fitted inside the annular groove. The flow guiding surface is located at one end of the sliding column. An adjustment mechanism is provided on one side of the sliding column.

[0007] Preferably, the slide is tightly fitted to the inner wall of the valve core housing through a sealing ring, and the guide surface is configured with an arc-shaped structure.

[0008] Preferably, the limiting block is a rectangular structure, and the limiting block is slidably connected inside the guide groove, with the inner wall of the guide groove fitting against the outer wall of the limiting block.

[0009] Preferably, the inlet and outlet are connected, and the outlet has a conical structure.

[0010] Preferably, the adjusting mechanism includes a fixing hole, a fixing column, a spring, a fixing cover, an end cap, and a threaded column. One end of the valve core housing is fixedly connected to the end cap. A fixing hole is opened on one side of the sliding column. The fixing column is fixedly connected inside the fixing hole. One end of the spring is fixedly connected to one end of the fixing hole. The fixing cover is fixedly connected to the other end of the spring. The threaded column is rotatably connected to one side of the end cap.

[0011] Preferably, the threaded post is threaded through the end cap, and the inner wall of the fixing hole fits against the outer wall of the fixing cover.

[0012] Preferably, a limiting mechanism is provided at one end of the threaded post. The limiting mechanism includes an end plate, a groove, a buckle, and an insert plate. The end plate is fixedly connected to one end of the threaded post, the groove is formed on the outside of the end plate, the buckle is fixedly connected to the outside of the end plate, and the insert plate is slidably inserted into the inside of the groove.

[0013] Preferably, the inner wall of the groove fits against the outer wall of the insert plate, and two buckles are provided, with the insert plate inserted between the two buckles.

[0014] Compared with the prior art, this utility model provides a streamlined valve core structure that prevents particle accumulation, and has the following beneficial effects:

[0015] 1. The outer wall of the slide column fits snugly against the inner wall of the valve core housing, and with the sealing ring, it can prevent mud and sand from being trapped between the outer wall of the slide column and the inner wall of the valve core housing. The arc-shaped structure of the guide surface at one end of the slide column can guide the water flow during drainage. The arc surface design avoids dead corners and prevents mud and sand from accumulating at one end of the slide column. Combined with the conical flow channel at the outlet, it can accelerate the water flow and further carry away the mud and sand in the water, achieving a better effect in preventing mud and sand accumulation.

[0016] 2. During use, by turning the threaded column, the initial pressure of the spring is changed, thereby adjusting the pressure required for the slide column to open and close under pressure. This allows for adjustment based on the water pressure, improving the applicability of the valve core. After adjustment, the threaded column is limited by the slide plate to ensure stability and make operation more convenient. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1 - Figure 5 This embodiment of a streamlined valve core structure for preventing particle accumulation includes a valve core housing 1, which includes an inlet 2 and an outlet 3. An arc-shaped protrusion 4 is fixedly connected inside the valve core housing 1. A connecting mechanism is provided inside the valve core housing 1. The connecting mechanism includes a guide groove 5, a sliding column 6, a limiting block 7, an annular groove 8, a sealing ring 9, and a flow guiding surface 10. The guide groove 5 is opened inside the valve core housing 1. The sliding column 6 is located inside the valve core housing 1. The limiting block 7 is fixedly connected to the outside of the sliding column 6. The annular groove 8 is opened on the outside of the sliding column 6. The sealing ring 9 is sleeved on the inside of the annular groove 8. The flow guiding surface 10 is opened at one end of the sliding column 6. An adjustment mechanism is provided on one side of the sliding column 6. One end of the sliding column 6 abuts against the arc-shaped protrusion 4.

[0026] During use, water enters through inlet 2, and the water pressure pushes the slide column 6 to slide, compressing the spring 13 so that the slide column 6 does not block the outlet 3, and the water is discharged from the outlet 3. When the water pressure is low, the slide column 6 returns to its original position and blocks the outlet 3, achieving the effect of blocking water. The outer wall of the slide column 6 fits against the inner wall of the valve core housing 1, and with the sealing ring 9, it can prevent mud and sand from being trapped between the outer wall of the slide column 6 and the inner wall of the valve core housing 1. When the slide column 6 slides to drain water, the arc-shaped structure of the guide surface 10 at one end of the slide column 6 can guide the water flow. The arc surface can also prevent mud and sand from accumulating at one end of the slide column 6. Combined with the conical flow channel of the outlet 3, it can accelerate the water flow and further carry away the mud and sand in the water, achieving a better effect of preventing mud and sand accumulation.

[0027] Please see Figure 1 - Figure 3 The sliding column 6 is tightly fitted to the inner wall of the valve core housing 1 through the sealing ring 9. The guide surface 10 is set with an arc structure. The limiting block 7 is set with a rectangular structure. The limiting block 7 is slidably connected inside the guide groove 5. The inner wall of the guide groove 5 is fitted with the outer wall of the limiting block 7. The inlet 2 and the outlet 3 are connected. The outlet 3 is set with a conical structure.

[0028] Please see Figure 4 - Figure 5 The adjusting mechanism includes a fixing hole 11, a fixing post 12, a spring 13, a fixing cover 14, an end cap 15, and a threaded post 16. One end of the valve core housing 1 is fixedly connected to the end cap 15. A fixing hole 11 is provided on one side of the sliding post 6. The fixing post 12 is fixedly connected inside the fixing hole 11. One end of the spring 13 is fixedly connected to one end of the fixing hole 11. The fixing cover 14 is fixedly connected to the other end of the spring 13. The threaded post 16 is rotatably connected to one side of the end cap 15. A limit mechanism is provided at one end of the threaded post 16. The limit mechanism includes an end plate 17, a groove 18, a buckle 19, and a insert plate 20. The end plate 17 is fixedly connected to one end of the threaded post 16. The groove 18 is opened on the outside of the end plate 17. The buckle 19 is fixedly connected to the outside of the end plate 17. The insert plate 20 is slidably inserted into the inside of the groove 18.

[0029] During use, the position of the fixed cover 14 can be changed by turning the threaded column 16, and the spring 13 can be compressed to change the initial pressure of the spring 13, thereby adjusting the pressure required for the sliding column 6 to open and close under pressure. This achieves the effect of adjusting according to the water pressure, improving the applicability range of the valve core. After adjustment, the insert plate 20 is inserted between the two clips 19, and the insert plate 20 is inserted into the groove 18 to limit the threaded column 16, ensuring stability after adjustment and making operation more convenient.

[0030] Please see Figure 4 - Figure 5The threaded post 16 is threaded through the end cap 15. The inner wall of the fixing hole 11 fits against the outer wall of the fixing cover 14. The inner wall of the groove 18 fits against the outer wall of the insert plate 20. There are two buckles 19. The insert plate 20 is inserted between the two buckles 19.

[0031] The working principle of the above embodiments is as follows:

[0032] During use, water enters through inlet 2, and the water pressure pushes the slide column 6 to slide, compressing the spring 13 so that the slide column 6 does not block the outlet 3, and the water is discharged from the outlet 3. When the water pressure is low, the slide column 6 returns to its original position and blocks the outlet 3, achieving the effect of blocking water. The outer wall of the slide column 6 fits against the inner wall of the valve core housing 1, and with the sealing ring 9, it can prevent mud and sand from being between the outer wall of the slide column 6 and the inner wall of the valve core housing 1. When the slide column 6 slides to drain water, the arc-shaped structure of the guide surface 10 at one end of the slide column 6 can guide the water flow. The arc surface can also prevent mud and sand from accumulating at one end of the slide column 6. Combined with the conical flow channel of the outlet 3, it can accelerate the water flow and further carry away the mud and sand in the water, achieving a better effect of preventing mud and sand accumulation.

[0033] During use, the position of the fixed cover 14 can be changed by turning the threaded column 16, and the spring 13 can be compressed to change the initial pressure of the spring 13, thereby adjusting the pressure required for the sliding column 6 to open and close under pressure. This achieves the effect of adjusting according to the water pressure, improving the applicability range of the valve core. After adjustment, the insert plate 20 is inserted between the two clips 19, and the insert plate 20 is inserted into the groove 18 to limit the threaded column 16, ensuring stability after adjustment and making operation more convenient.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
