[0002] Fluoroplastic-lined valves, also known as fluoroplastic-lined corrosion-resistant valves, are made by molding or nesting polytetrafluoroethylene resin or its derivatives into the inner wall of the pressure-bearing components of steel or cast iron valves. This method is also suitable for lining various pressure vessels and pipeline accessories, or the outer surface of internal valve parts. Utilizing its excellent resistance to highly corrosive media, fluoroplastic-lined valves are used to manufacture various valves and pressure vessels. The use of fluoroplastic-lined valves is unavoidable in industries such as petroleum, printing, and chemicals.

[0003] However, during the use of fluoropolymer-lined valves, the fluoropolymer-lined ball valves are subjected to long-term vibration due to the impact of gas and liquid, which has a certain impact on the fluoropolymer-lined valves. After long-term vibration, the sealing performance of the fluoropolymer-lined valves will decrease, and leakage problems will occur after a long period of use. Therefore, a fluoropolymer-lined ball valve with shock absorption and leakage prevention is proposed to address the above problems. Utility Model Content

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a fluoropolymer-lined ball valve with shock absorption and leak prevention features. (Refer to...) Figure 1 and Figure 2A fluoropolymer-lined ball valve with shock absorption and leak prevention features includes a fluoropolymer-lined valve body 1. A connecting plate 10 is fixedly connected to the inner wall of the fluoropolymer-lined valve body 1. A support plate 8 is fixedly connected to the bottom of the connecting plate 10. A base 7 is movably connected to the bottom of the support plate 8. A buffer support leg 12 is fixedly connected to the bottom of the base 7. A buffer shock absorption mechanism 2 is provided on the inner wall of the fluoropolymer-lined valve body 1. The buffer shock absorption mechanism 2 includes a fixing ring 203, which is movably connected to the inner wall of the fluoropolymer-lined valve body 1. Support blocks 201 are fixedly connected to the surface of the fixing ring 203. There are four support blocks 201, one side of which contacts the inner wall of the fluoropolymer-lined valve body 1. A connecting plate 10 is fixedly connected to the inner wall of the fixing ring 203. Pipe 202, one end of which is fixedly connected to a buffer tank 205, a buffer mesh 204 is fixedly connected to the inner wall of the buffer tank 205, and a plug 206 is fixedly connected to one side of the buffer tank 205; by setting the buffer and shock absorption mechanism 2, the fluoropolymer-lined valve body 1 can be prevented from being subjected to the impact of gas and liquid for a long time and be in a state of vibration, thereby reducing the impact of vibration on the fluoropolymer-lined valve body 1. At the same time, it can prevent the fluoropolymer-lined valve body 1 from being subjected to vibration for a long time, thus reducing the leakage problem of the fluoropolymer-lined valve body 1 after long-term use, and achieving the purpose of reducing the rotation of the fluoropolymer-lined valve body 1 during use and affecting the sealing effect.

[0026] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 The support plate 8 and the base 7 are respectively fixedly connected to the bottom and top of a first retaining ring 16 and a second retaining ring 11. There are four first retaining rings 16 and four second retaining rings 11. A damping telescopic rod 17 is provided between the opposite sides of the first retaining rings 16 and the second retaining rings 11. The bottom of the damping telescopic rod 17 is fixedly connected to the top of the base 7. The telescopic end of the damping telescopic rod 17 passes through to the top of the first retaining ring 16 and is fixedly connected to the bottom of the support plate 8. Rubber buffer pads 15 are fixedly connected to the inner walls of the first retaining rings 16 and the second retaining ring 11. A spring 9 is movably fitted onto the surface of 17. The bottom of the spring 9 is in close contact with the bottom of one of the rubber buffer pads 15, and the top of the spring 9 is in close contact with the bottom of the other rubber buffer pad 15. By using the first retaining ring 16, the second retaining ring 11, the damping telescopic rod 17, the rubber buffer pads 15 and the spring 9 in combination, the vibration generated by the fluoropolymer-lined valve body 1 during use can be further reduced, thereby preventing the fluoropolymer-lined valve body 1 from leaking due to vibration, and achieving the purpose of further reducing the vibration of the fluoropolymer-lined valve body 1 during use.

[0027] Reference Figure 1 and Figure 3A support rod 6 is provided on one side of the support plate 8, and a camera 3 is fixedly connected to the top of the support rod 6. By using the support rod 6 and the camera 3 together, users can easily monitor the fluoropolymer-lined valve body 1 during use. When the fluoropolymer-lined valve body 1 leaks, it can be detected in time, thereby avoiding losses and achieving the purpose of monitoring the fluoropolymer-lined valve body 1.

[0028] Reference Figure 4 A fixing rod 4 is fixedly connected to one side of the support plate 8, and a fixing sleeve 5 is fixedly connected to one side of the fixing rod 4. The inner wall of the fixing sleeve 5 is movably connected to the surface of the support rod 6. By setting the fixing rod 4 and the fixing sleeve 5 together, the support rod 6 can be supported, increasing the stability of the support rod 6 for the user, and achieving the purpose of supporting the support rod 6.

[0029] Reference Figure 4 A threaded sleeve 14 is fixedly connected to the inner wall of the fixed sleeve 5, and a knob 13 is threadedly connected to the inner wall of the threaded sleeve 14. One end of the knob 13 is in close contact with one side of the support rod 6. By setting the threaded sleeve 14 and the knob 13 to work together, the support rod 6 placed in the fixed sleeve 5 can be limited, making the support rod 6 more stable and firm when in use, thereby further increasing the stability and firmness of the support rod 6 in use.

[0030] Working Principle: To enhance the shock absorption effect of the PTFE-lined valve body 1 during use, when the user connects the PTFE-lined valve body 1 to the pipeline, the gas and liquid in the pipeline enter the PTFE-lined valve body. First, they enter the buffer tank 205 through the connecting pipe 202. The buffer mesh 204 in the buffer tank 205 disperses the impact force of the gas or liquid, increasing the shock resistance of the PTFE-lined valve body 1 during use. The remaining vibration is transmitted along with the PTFE-lined valve body 1, so that the vibration force enters the support plate 8 through the connecting plate 10. When the vibration force is transmitted to the base 7, the first retaining ring 16, the second retaining ring 11, the damping telescopic rod 17, the rubber buffer pad 15, and the spring... With the cooperation of 9, the vibration generated by the fluoropolymer-lined valve body 1 during use can be further reduced, and the generated vibration force can be dispersed and canceled, thereby avoiding leakage caused by vibration of the fluoropolymer-lined valve body 1. In order to avoid leakage of the fluoropolymer-lined valve body 1 during use, the user can monitor the fluoropolymer-lined valve body 1 in real time through the camera 3. When monitoring the fluoropolymer-lined valve body 1, the user inserts the support rod 6 into the fixing sleeve 5. Then, when the support rod 6 is adjusted to a suitable position, the user rotates the knob 13, so that the knob 13 moves in the threaded sleeve 14. When the knob 13 moves, it contacts the support rod 6, and the support rod 6 is fixed in the fixing sleeve 5.
