Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a wear-resistant eccentric V-shaped regulating semi-ball valve. Background Art

[0002] In the existing ball valve technology, the wear resistance, sealing and fluid control accuracy of the valve device have always been the key technical problems. During the long-term use of traditional ball valves, due to the changes in fluid pressure, wear and the decline in sealing performance, the valve life is often shortened, the maintenance cost is increased, and there may even be safety hazards such as fluid leakage.

[0003] In particular, in some application scenarios that require precise control of fluid flow and pressure, traditional ball valves often fail to meet the requirements. For example, in the chemical, petroleum, and natural gas industries, precise control of fluids and long-term stable operation of valves are essential. However, existing valve devices often exhibit problems such as insufficient wear resistance and reduced sealing performance when facing high pressure, high flow rate, or corrosive fluids. In view of this, we propose a wear-resistant eccentric V-type regulating semi-ball valve. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0023] A wear-resistant eccentric V-shaped regulating hemispherical valve comprises a valve body 1, a valve core 4 is installed in the valve body 1, a V-shaped groove is provided on the valve core 4, an adjustment disk 2 is installed above the valve body 1, a driving shaft 20 at the bottom of the adjustment disk 2 is fixed to the top center of the valve core 4, a first sealing gasket 10 is fixedly connected to the inner wall of the valve body 1, a second sealing gasket 40 is fixedly installed on the outer wall of the valve core 4, a movable plate 41 is provided at the center of the outer wall of the valve core 4, and a spring 43 is installed between the movable plate 41 and the valve core 4. This scheme provides a valve device with a compact structure and comprehensive functions. The valve core 4 in the valve body 1 is designed with a V-shaped groove, so that the fluid control is more precise. The rotation of the valve core 4 can be conveniently controlled by the adjustment disk 2 and the driving shaft 20, so as to realize the opening and closing of the valve. The first sealing gasket 10 on the inner wall of the valve body 1 and the second sealing gasket 40 on the outer wall of the valve core 4 ensure the sealing of the valve in the closed state, and can reduce the wear between the valve core 4 and the valve body 1. The combined design of the movable plate 41 and the spring 43 can absorb and buffer the change of fluid pressure to a certain extent, thereby enhancing the stability and durability of the valve.

[0024] As a preferred embodiment of the present invention, connecting pipes are integrally formed on both sides of the valve body 1, and flanges 3 are welded at the ends of the connecting pipes. Such a design enables the valve to be conveniently connected to other pipeline systems, thereby improving the versatility and installation convenience of the valve.

[0025] As a preferred embodiment of the present invention, when the valve core 4 is fixed or rotated, the first sealing gasket 10 and the second sealing gasket 40 are tightly fitted. This design ensures that the valve can maintain good sealing performance in any state and effectively prevent fluid leakage.

[0026] As a preferred embodiment of the present invention, two plug shafts 42 are symmetrically integrally formed on one side of the movable plate 41 close to the valve body 1, and a slot 45 for receiving the plug shaft 42 for plugging and connecting is provided on the valve body 1. Such a structural design enables the movable plate 41 to move flexibly within a certain range, and the connection between the plug shaft 42 and the slot 45 also enhances the stability of the movable plate 41, preventing it from shifting during use.

[0027] As a preferred embodiment of the present invention, the plug shaft 42 is located in the spring 43, and a mounting groove 44 for mounting the spring 43 is provided in the slot 45. Such a design enables the spring 43 to be stably mounted between the valve core 4 and the slot 45, providing a stable elastic support for the movable plate 41.

[0028] As a preferred embodiment of the present invention, when the spring 43 is at its original length, the movable plate 41 is away from the valve body 1. Such a design ensures that when there is no external force, sufficient deformation space is provided for the spring 43 to meet the sealing requirements under different pressures.

[0029] As a preferred embodiment of the present invention, the plug shaft 42 is tightly fitted with the slot 45, and the plug shaft 42 does not separate from the slot 45 during the movement of the movable plate 41. This design ensures both the flexibility and stability of the movable plate 41. The tight fit between the plug shaft 42 and the slot 45 effectively prevents fluid leakage through these joints, thereby improving the overall sealing performance of the valve.

[0030] The wear-resistant eccentric V-shaped regulating semi-ball valve of the utility model is used:

[0031] First, the hemispherical valve is connected to other pipeline systems through the connecting pipes and flanges 3 on the left and right sides of the valve body 1 to build a fluid control channel. The valve core 4 installed inside the valve body 1 is a key component for controlling the flow of fluid, and the V-shaped groove opened on it is used to adjust the flow of fluid.

[0032] When the valve needs to be opened or closed, the adjusting disk 2 is operated so that the driving shaft 20 at the bottom drives the valve core 4 to rotate in the valve body 1. This rotational action changes the alignment between the V-groove and the fluid channel, thereby controlling the amount of fluid passing through. When the V-groove is completely aligned with the fluid channel, the valve is in a fully open state and the fluid can pass smoothly; when the V-groove is misaligned with the fluid channel, the valve gradually closes, and the amount of fluid passing through is reduced until it is completely blocked.

[0033] During the valve closing process, the first sealing gasket 10 on the inner wall of the valve body 1 and the second sealing gasket 40 on the outer wall of the valve core 4 fit closely together to form an effective seal to prevent fluid leakage. This double sealing design not only enhances the sealing performance of the valve, but also reduces direct wear between the valve core 4 and the valve body 1, thereby extending the service life of the valve.

[0034] In addition, the combination of the movable plate 41 and the spring 43 arranged at the center of the outer wall of the valve core 4 plays a role of buffering and stabilization. When the fluid pressure changes, the movable plate 41 can move flexibly under the support of the spring 43 to absorb pressure fluctuations and maintain the stability of the valve. At the same time, the plug shaft 42 on the movable plate 41 fits tightly with the slot 45 on the valve body 1, ensuring that the movable plate 41 will not deviate from the predetermined track during movement, further enhancing the stability and reliability of the valve.

[0035] In summary, the wear-resistant eccentric V-shaped regulating semi-ball valve of the utility model realizes efficient, reliable and durable fluid control function through precise fluid control, double sealing design and buffering stable structure.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model.
