Description

Technical Field

[0001] This utility model relates to the field of soft-seal ball valve technology, and in particular to a soft-seal ball valve that is resistant to chewing. Background Technology

[0002] In many fields such as petrochemicals, municipal water supply, and agricultural irrigation, soft-seal ball valves are widely used in media control within pipeline systems due to their excellent sealing performance and low fluid resistance. However, in open environments such as outdoor and field operations, soft-seal ball valves are often exposed to the elements for extended periods, facing the risk of being chewed by animals. Once the valve body, connecting pipes, and other components are damaged by chewing, it can not only lead to media leakage and affect the normal operation of the system, but also cause safety accidents or environmental pollution.

[0003] Existing soft-seal ball valves primarily focus on optimizing sealing performance and fluid control functions in their structural design. For example, by using soft materials such as rubber or PTFE as the valve seat, a tight fit between the ball and the seat is achieved, resulting in a good sealing effect. For the connection between the valve body and the pipeline, flange connections or welding are commonly used to ensure connection strength and sealing. Its working principle involves the valve stem driving the ball to rotate, thereby opening and closing the valve and controlling the flow of the medium.

[0004] However, in practical applications, sealed ball valves are susceptible to being chewed by animals such as rats and rabbits, leading to damage to critical components such as the valve body and connecting pipes, and consequently causing problems such as media leakage and equipment failure. This damage not only increases maintenance costs and workload but also poses safety hazards and economic losses due to media leakage. Therefore, a chew-resistant soft-seal ball valve is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a soft-seal ball valve that is resistant to chewing, aiming to improve the problem that soft-seal ball valves in the prior art are easily chewed by animals during use, resulting in damage to the valve body and key components.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A soft-seal ball valve with anti-gnawing properties includes a valve body, a valve stem rotatably connected inside the valve body, connecting pipes fixedly connected to both sides of the valve body, a protective component provided on the side wall of the valve body, and a dispersion component provided on the side wall of the valve body.

[0008] The protective assembly includes a first protective cover, one side wall of which is slidably connected to the side wall of the connecting pipe; a second protective cover is rotatably connected to one side wall of the first protective cover; a fixed frame is fixedly connected to one side wall of the first protective cover; a fixed block is fixedly connected to the side wall of the second protective cover; a connecting frame is fixedly connected to the side wall of the fixed frame; a locking post is slidably connected inside the fixed frame; a limit block is fixedly connected to the side wall of the locking post; a connecting rod is fixedly connected to the side wall of the limit block; a first spring is sleeved on the side wall of the connecting rod; one end of the first spring is fixedly connected to the inside of the connecting frame; and the other end of the first spring is fixedly connected to the side wall of the limit block.

[0009] As a further description of the above technical solution:

[0010] The dispersion component includes a fixing rod, and the side walls of the first protective cover and the second protective cover are fixedly connected to a connecting block, with the side wall of the fixing rod fixedly connected to the side wall of the connecting block.

[0011] As a further description of the above technical solution:

[0012] The side wall of the fixed rod is provided with a fixing plate, and a sleeve is fixedly connected to the side wall of the fixing plate.

[0013] As a further description of the above technical solution:

[0014] A pressing block is fixedly connected to the side wall of the fixing rod, and the fixing rod and the side wall of the pressing block are slidably connected inside the sleeve.

[0015] As a further description of the above technical solution:

[0016] A second spring is fixedly connected inside the sleeve, and the side wall of the second spring is fixedly connected to the side wall of the pressing block.

[0017] As a further description of the above technical solution:

[0018] The first protective cover and the second protective cover are rotatably connected to the side wall of the valve body, and the first protective cover and the second protective cover are in contact with each other.

[0019] As a further description of the above technical solution:

[0020] The side wall of the fixing block is slidably connected inside the fixing frame, and the side wall of the card post is slidably connected inside the fixing block and the connecting frame.

After the external force disappears, the second spring resets and pushes the component back to its original position, reducing the impact on the valve body and the protective component. This solves the problem that the protective component and valve body are easily damaged when the ball valve is subjected to external impact. The above technical solution improves the ball valve's ability to disperse external impact force. Attached Figure Description

[0034] 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.

[0035] Reference Figures 1-5 This utility model provides an embodiment of a soft-seal ball valve designed to prevent chewing, comprising a valve body 1, a valve stem 2 rotatably connected inside the valve body 1, connecting pipes 3 fixedly connected to both sides of the valve body 1, a protective assembly and a dispersion assembly provided on the side wall of the valve body 1; the protective assembly includes a first protective cover 4, the side wall of the first protective cover 4 slidably connected to the side wall of the connecting pipe 3, and a second protective cover 5 rotatably connected to the side wall of the first protective cover 4. The first protective cover 4 and the second protective cover 5 are used to enclose the valve body 1, preventing animals from chewing on the valve body 1 and protecting the key components of the ball valve from damage. A fixing frame 6 is fixedly connected to the side wall of the first protective cover 4, and a fixing block 7 is fixedly connected to the side wall of the second protective cover 5. The fixing block 7 is used to cooperate with the fixing frame 6, and under the action of a locking post 9, the first protective cover 4 and the second protective cover 5 are fixedly connected. A connecting frame 8 is fixedly connected to the side wall of the fixing frame 6, and a locking post 9 is slidably connected inside the fixing frame 6. The locking post 9 is used to insert into the fixing block 7 and the fixing frame 6 to lock the first protective cover 4 and the second protective cover 5, preventing damage during use. When the device is accidentally opened, a limiting block 10 is fixedly connected to the side wall of the locking post 9. A connecting rod 11 is fixedly connected to the side wall of the limiting block 10. The connecting rod 11 connects the limiting block 10 and the first spring 12, transmitting the elastic force of the first spring 12 so that the locking post 9 can remain locked under the action of the elastic force. The first spring 12 is sleeved on the side wall of the connecting rod 11. The first spring 12 generates elastic force through its own elastic deformation to push the limiting block 10 and the locking post 9, keeping the locking post 9 locked and ensuring that the first protective cover 4 and the second protective cover 5 are locked together. The first spring 12 is fixedly connected at one end to the inside of the connecting frame 8, and the other end of the first spring 12 is fixedly connected to the side wall of the limiting block 10. The side walls of the first protective cover 4 and the second protective cover 5 are rotatably connected to the side wall of the valve body 1. The side walls of the first protective cover 4 and the second protective cover 5 are in contact with each other. The side wall of the fixing block 7 is slidably connected to the inside of the fixing frame 6. The side wall of the locking post 9 is slidably connected to the inside of the fixing block 7 and the connecting frame 8. The side wall of the limiting block 10 is slidably connected to the inside of the connecting frame 8. The side wall of the connecting rod 11 is slidably connected to the inside of the connecting frame 8.

[0036] Reference Figure 1 and Figure 6The dispersion component includes a fixing rod 16. A connecting block 13 is fixedly connected to the side walls of the first protective cover 4 and the second protective cover 5. The connecting block 13 connects the dispersion component and the protective component as a whole, enabling the dispersion component to disperse the external forces acting on the first protective cover 4 and the second protective cover 5. The side wall of the fixing rod 16 is fixedly connected to the side wall of the connecting block 13. A fixing plate 14 is provided on the side wall of the fixing rod 16. A sleeve 15 is fixedly connected to the side wall of the fixing plate 14. The sleeve 15 provides installation space for the fixing rod 16, the pressing block 17, and the second spring 18, and restricts their direction of movement. A pressing block 17 is fixedly connected to the side wall of the fixing rod 16. The fixing rod 16 and the pressing block 17 are slidably connected inside the sleeve 15. The pressing block 17 is used to bear external force and compress the second spring 18, and transmit the external force to the second spring 18. At the same time, it resets under the elastic force of the second spring 18, realizing the dispersion of external force. The second spring 18 is fixedly connected inside the sleeve 15. The side wall of the second spring 18 is fixedly connected to the side wall of the pressing block 17. The second spring 18 is used to absorb and disperse external force through elastic deformation, reducing the impact of external force on the valve body 1 and the protective component.

[0037] Working principle: During installation, first slide the protective cover 4 along the connecting pipe 3 to the appropriate position, then pull the connecting rod 11 to drive the limiting block 10 to slide inside the connecting frame 8. The locking post 9 will then retract into the connecting frame 8. At the same time, the limiting block 10 compresses the first spring 12. After the locking post 9 is completely separated from the fixed frame 6, rotate the protective cover 5 to make it fit with the protective cover 4 and together wrap the valve body 1. At this time, the fixing block 7 slides into the fixed frame 6. Release the connecting rod 11, the first spring 12 returns to its deformation, pushes the limiting block 10 to reset, and drives the locking post 9 to insert into the fixed frame 6 and the fixing block 7, thereby fixing the protective cover 4 and the protective cover 5 to form a protective structure and prevent animals from gnawing on the valve body 1.

[0038] When the protective cover 4 and the protective cover 5 are impacted by an external force, the connecting block 13 transmits the force to the fixing rod 16. The fixing rod 16 drives the pressing block 17 to slide inside the sleeve 15 and compress the second spring 18. The second spring 18 absorbs the energy of the external force through elastic deformation and disperses the concentrated impact force. When the external force disappears, the second spring 18 restores its deformation and pushes the pressing block 17 and the fixing rod 16 to reset, thereby reducing the impact of the external force on the valve body 1 and the protective components and playing a protective role.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
