Description

Technical Field

[0001] This utility model belongs to the field of ball valve technology, and in particular relates to a ball valve with elastic sealing. Background Technology

[0002] A ball valve is a common type of valve used in pipeline systems, its main function being to control the flow of fluid. Its working principle is based on a spherical valve body with a through-hole; rotating the ball opens or closes the flow passage in the pipeline. Ball valves offer advantages such as rapid opening and closing, precise flow control, simple structure, and good sealing performance, and are widely used in industries such as petroleum, natural gas, water treatment, chemical, and power generation.

[0003] Existing technologies cannot adequately address the installation problem of resilient seals in ball valves; therefore, we propose a ball valve with resilient seals. Utility Model Content

[0004] The purpose of this invention is to provide a ball valve with an elastic seal, which solves the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a ball valve with elastic sealing, including a ball valve, a connecting pipe that is connected through the circumference of the ball valve, a control shaft that is provided on the circumference of the ball valve, and an elastic sealing device that is provided on the side of the connecting pipe.

[0007] The resilient sealing device includes a slot formed on the side of the connecting pipe. A sliding groove is formed on the circumferential surface of the connecting pipe. A rubber rod is slidably connected to the inner side of the slot. An resilient sealing gasket is fixedly connected to one end of the rubber rod. A fixing pin is slidably connected to the inner side of the sliding groove. A slot is formed on the circumferential surface of the fixing pin, and a pin is slidably connected to the inner side of the slot. This resilient sealing device, through multiple sliding and fixed connection designs, improves sealing performance, durability, and adjustability, providing a reliable sealing solution between the connecting pipe and other components, preventing leakage, and ensuring stable system operation.

[0008] Furthermore, the circumferential surface of the pin is slidably connected to the inner surface of the slot. This slidable connection between the circumferential surface of the pin and the inner surface of the slot serves to guide, adjust, reduce friction, enhance stability, and facilitate maintenance, enabling the entire elastic sealing device to maintain good sealing performance in varying working environments.

[0009] Furthermore, the side of the rubber rod lies on the displacement trajectory of the fixing pin, and four slots are provided, arranged in a circumferential array along the circumference of the connecting pipe. This design of four slots arranged in a circumferential array along the connecting pipe, combined with the cooperation of the fixing pin and the rubber rod, helps improve the uniformity, stability, durability, and performance of the elastic sealing device, ensuring that the entire system can achieve effective sealing and prevent leakage under different operating conditions.

[0010] Furthermore, four grooves are provided and arranged in a circumferential array along the side of the connecting pipe. The four grooves arranged in a circumferential array along the connecting pipe can effectively distribute pressure, reduce friction, improve the stability of the elastic sealing device, enhance fatigue resistance, and maintain the normal operation of the device under different working conditions.

[0011] Furthermore, a leakage alarm device is provided on the circumferential surface of the connecting pipe. The leakage alarm device includes a connecting rod, one end of which is fixedly connected to the circumferential surface of the connecting pipe. A leakage monitoring module is fixedly connected to the other end of the connecting rod. A fixing plate is fixedly connected to the top of the leakage monitoring module, and a cover plate is connected through the side of the fixing plate. A fixing rod is fixedly connected to the inner side of the slot, and a movable groove is formed on the inner side of the slot. An extension rod is slidably connected to the inner side of the movable groove, and a return spring is fixedly connected to the side of the extension rod. A circular push plate is fixedly connected to the circumferential surface of the rubber rod. This system, through the cooperation of multiple components, will trigger an alarm when a leakage occurs, ensuring timely handling of the leakage problem and protecting the safe operation of the pipeline.

[0012] Furthermore, one end of the return spring is fixedly connected to the side of the fixed rod, and one end of the extension rod is fixedly connected to the side of the cover plate. The combination of the return spring and the extension rod provides restoring force and flexibility, ensuring that the extension rod automatically resets, maintaining normal working condition, and improving the reliability and durability of the system.

[0013] Furthermore, the side of the extension rod lies on the displacement trajectory of the circular push plate. This alignment helps ensure coordinated movement between the two, enabling precise control, stable operation, and optimized leakage monitoring.

[0014] This utility model has the following beneficial effects:

[0015] This invention achieves its effect through the interplay of components such as slots, grooves, and rubber rods. The operator inserts the rubber rod into the slot, ensuring tight contact between the elastic sealing gasket and the connecting pipe. Then, a fixing pin is inserted to secure the rubber rod within the slot. Finally, the pin is inserted into the slot to lock it in place. This improves sealing performance, durability, and adjustability, providing a reliable sealing solution between the connecting pipe and other components, preventing leakage, and ensuring stable system operation.

[0016] This invention utilizes the coordinated operation of components such as a circular push plate and a leakage detection module. When the rubber rod moves horizontally, it drives the circular push plate to move horizontally as well. This movement of the push plate, in turn, drives the extension rod to move horizontally, causing the cover plate to slide open and revealing the leakage detection module. When a leak occurs at the connection pipe, water droplets falling onto the leakage detection module trigger an alarm. This ensures that the leakage detection module will sound an alarm when a leak occurs, allowing for timely intervention and protecting the safe operation of the pipeline.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7 The present invention is a ball valve with elastic sealing, including a ball valve 1, a connecting pipe 2 that is connected through the circumference of the ball valve 1, a control shaft 3 that is provided on the circumference of the ball valve 1, and an elastic sealing device 4 that is provided on the side of the connecting pipe 2.

[0030] The elastic sealing device 4 includes a slot 41 formed on the side of the connecting pipe 2. A groove 42 is formed on the circumferential surface of the connecting pipe 2. A rubber rod 43 is slidably connected to the inner side of the slot 41. An elastic sealing gasket 44 is fixedly connected to one end of the rubber rod 43. A fixing pin 45 is slidably connected to the inner side of the groove 42. A slot 46 is formed on the circumferential surface of the fixing pin 45. A pin 47 is slidably connected to the inner side of the slot 46. This elastic sealing device 4, through various sliding and fixed connection designs, improves sealing performance, durability, and adjustability, providing a reliable sealing solution between the connecting pipe 2 and other components, preventing leakage, and ensuring stable system operation.

[0031] The circumferential surface of the pin 47 is slidably connected to the inner surface of the slot 41. This slidable connection between the circumferential surface of the pin 47 and the inner surface of the slot 41 serves to guide, adjust, reduce friction, enhance stability, and facilitate maintenance, enabling the entire elastic sealing device 4 to maintain good sealing performance in varying working environments.

[0032] The side of the rubber rod 43 lies on the displacement trajectory of the fixing pin 45. Four slots 41 are provided and arranged in a circumferential array along the circumference of the connecting pipe 2. This design of four slots 41 arranged along the circumference of the connecting pipe 2, combined with the cooperation of the fixing pin 45 and the rubber rod 43, helps improve the uniformity, stability, durability, and performance of the elastic sealing device 4, ensuring that the entire system can achieve effective sealing and prevent leakage under different operating conditions.

[0033] Four grooves 42 are provided and arranged in a circular array along the side circumference of the connecting pipe 2. The four grooves 42 arranged in a circular array along the side circumference of the connecting pipe 2 can effectively distribute pressure, reduce friction, improve the stability of the elastic sealing device 4, enhance fatigue resistance, and maintain the normal operation of the device under different working conditions.

[0034] A leak alarm device 5 is installed on the circumferential surface of the connecting pipe 2. The leak alarm device 5 includes a connecting rod 51, one end of which is fixedly connected to the circumferential surface of the connecting pipe 2. A leak monitoring module 52 is fixedly connected to the other end of the connecting rod 51. A fixing plate 53 is fixedly connected to the top of the leak monitoring module 52. A cover plate 54 is connected through the side of the fixing plate 53. A fixing rod 55 is fixedly connected to the inner side of the slot 41. A moving groove 56 is formed on the inner side of the slot 41. An extension rod 57 is slidably connected to the inner side of the moving groove 56. A return spring 58 is fixedly connected to the side of the extension rod 57. A circular push plate is fixedly connected to the circumferential surface of the rubber rod 43. This system, through the cooperation of multiple components, will issue an alarm when a leak occurs, ensuring that the leak problem can be dealt with in a timely manner, thereby protecting the safe operation of the pipeline.

[0035] One end of the return spring 58 is fixedly connected to the side of the fixed rod 55, and one end of the extension rod 57 is fixedly connected to the side of the cover plate 54. The combination of the return spring 58 and the extension rod 57 provides restoring force and flexibility, ensuring that the extension rod 57 automatically resets, maintaining normal working condition, and improving the reliability and durability of the system.

[0036] The side of the extension rod 57 lies on the displacement trajectory of the circular push plate. This alignment helps ensure coordinated movement between the two, enabling precise control, stable operation, and optimized leak detection.

[0037] One specific application of this embodiment is as follows: First, the operator inserts the rubber rod 43 into the pre-designed slot 41, ensuring that the elastic sealing gasket 44 is in full contact with the surface of the connecting pipe 2, forming a tight seal. Next, the operator inserts the fixing pin 45 into the designated position. Through the action of the fixing pin 45, the rubber rod 43 is firmly fixed in the slot 41, ensuring that its position does not move or shift. Finally, the operator mates the pin 47 with the slot 46, inserts it, and ensures that it is fully locked, thereby stabilizing the entire assembly, ensuring the best sealing effect, and preventing any loosening or leakage.

[0038] When the rubber rod 43 moves horizontally, it drives the circular push plate to move horizontally. The horizontal movement of the circular push plate drives the extension rod 57 to move horizontally. The horizontal movement of the extension rod 57 drives the cover plate 54 to slide open, thereby exposing the water leakage monitoring module 52. When water leakage occurs at the connecting pipe 2, an alarm is triggered when water droplets fall onto the water leakage monitoring module 52. When the elastic sealing gasket 44 is removed, the reset spring 58 pushes the extension rod 57 to return to its horizontal position through its own elastic force. The horizontal return of the extension rod 57 drives the cover plate 54 to return to its position, thereby sealing the contact area of ​​the water leakage monitoring module 52.
