A second spring is welded to the inner side of the inner cavity of the connecting block.

[0004] However, in actual use, when it is necessary to open the valve body, the valve disc can only be pulled out as a whole to transport water, which makes the whole operation quite laborious. At the same time, it consumes a lot of force when pulling the round rod as a whole, which limits the whole operation. Therefore, improving and perfecting the above problems has become an urgent issue to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide an energy-saving fluoropolymer-lined shut-off valve to solve the problems mentioned in the background art, which are that when the valve body needs to be opened, the valve disc can only be pulled out as a whole to transport water, making the overall operation relatively laborious. At the same time, the force required to pull the round rod as a whole is large, thus limiting the overall operation.

[0024] 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.

[0025] Please see Figures 1-5 One embodiment provided by this utility model:

[0026] The energy-saving fluoropolymer-lined shut-off valve, the valve disc body 5 and the spring telescopic cylinder 14 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. It includes a first housing 1, a second housing 2 installed on the top surface of the first housing 1, a connecting rod 4 installed inside the second housing 2, a top plate 3 installed on the top surface of the connecting rod 4, a sealing component installed at the lower end of the connecting rod 4, an auxiliary component installed on the outer surface of the connecting rod 4, and an adapter component installed at the lower end of the first housing 1.

[0027] The sealing assembly includes a valve disc body 5, which is mounted on the lower surface of the connecting rod 4, and a groove 10 is provided on the right side surface of the valve disc body 5.

[0028] The auxiliary components include a stabilizing ring 12 and a stabilizing plate 15. The stabilizing plate 15 is installed on the left and right sides of the top plate 3, and a connecting post 16 is installed on the top surface of the stabilizing plate 15. A connecting plate 17 is installed on the top surface of the connecting post 16, and two sets of connecting posts 16 are provided. When the valve disc body 5 moves away from the inside of the adapter ring 7, the trough 10 can then transport the liquid delivered by the inlet pipe 6 from the inside of the outlet cylinder 8 and the outlet pipe 9. Then, when the valve disc body 5 is reinstalled into the inside of the adapter ring 7, first, hold the connecting plate 17 and rotate it, which will drive the top plate 3 and the connecting rod 4 to rotate. At this time, the connecting rod 4 releases the threaded connection with the threaded cylinder 11. Then, when the connecting rod 4 releases the threaded connection, the elasticity inside the spring telescopic cylinder 14 begins to return to its original position, which can quickly drive the stabilizing ring 12 downwards, thus driving the valve disc body 5 downwards to fit into the inside of the adapter ring 7, sealing the outlet cylinder 8 as a whole. Therefore, this setup, through the cooperation of the auxiliary components and the adapter components, can seal the outlet cylinder 8 simply by releasing the threaded connection between the connecting rod 4 and the threaded cylinder 11. Then, the connecting rod 4, through the elasticity of the spring telescopic cylinder 14, automatically drives the valve disc body 5 into the inside of the adapter ring 7 to seal the outlet cylinder 8. The overall operation is quite convenient. Meanwhile, the connecting plate 17, connecting column 16, and stabilizing plate 15 are all connected to the top plate 3. When it is necessary to pull or rotate the top plate 3, only the connecting plate 17 needs to be operated. This setting saves effort and facilitates operation. The adapter ring 7 in this application has sealing and corrosion resistance with the valve disc body 5.

[0029] A rotating cylinder 18 is installed on the outer surface of the second housing 2, and an inlet pipe 6 is installed on the right side of the first housing 1. A limiting block 19 is installed inside the rotating cylinder 18. When the valve disc body 5 and the adapter ring 7 are fitted together, rotating the limiting block 19 inside the rotating cylinder 18 will cause the lower surface of the limiting block 19 to abut against the upper surface of the top plate 3, thereby fixing the position of the top plate 3 and improving the sealing effect of the valve disc body 5.

[0030] The adapter assembly includes an adapter ring 7, which is installed on the lower surface of the first housing 1. An outlet cylinder 8 is installed inside the adapter ring 7. An outlet pipe 9 is installed on the left side of the outlet cylinder 8. The valve body 5 and the adapter ring 7 are mutually adapted. A stabilizing ring 12 is installed on the outer surface of the connecting rod 4, and a threaded cylinder 11 is installed inside the second housing 2. At this time, the valve body 5 and the adapter ring 7 are sealed together, ensuring the overall sealing of the valve body. When it is necessary to allow flow between the inlet pipe 6 and the outlet pipe 9, the connecting rod 4 is pulled upwards. The valve body 5 will slowly disengage from the adapter ring 7. When the trough 10 is no longer blocked by the adapter ring 7, the trough 10 can allow liquid to flow. Therefore, the liquid pressure will not be pressing against the upper surface of the valve body 5, thus reducing the upward pulling force on the valve body 5. This results in a better overall pulling effect and more convenient operation. By rotating the connecting rod 4, the pulled connecting rod 4 can be threaded and fixed inside the threaded cylinder 11, making the overall operation convenient and energy-saving. Thus, through the cooperation of the sealing component and the auxiliary component, when it is necessary to connect the inlet pipe 6 and the outlet pipe 9, the valve disc body 5 can be easily pulled upward and then threaded and fixed inside the threaded cylinder 11. The overall operation is time-saving and labor-saving, and the liquid can be transported in advance, resulting in a better overall operation effect.

[0031] Side blocks 13 are fixedly connected to both sides of the stabilizing ring 12. A spring telescopic cylinder 14 is installed on the top surface of the side block 13, and the top surface of the spring telescopic cylinder 14 contacts the lower surface of the threaded cylinder 11. A spring is installed inside the spring telescopic cylinder 14. When the valve disc body 5 moves upward, the top surface of the spring telescopic cylinder 14 will squeeze the lower surface of the threaded cylinder 11, causing the spring telescopic cylinder 14 to contract. Then, when the connecting rod 4 is rotated, the top surface of the spring telescopic cylinder 14 will slide inside the groove at the lower end of the threaded cylinder 11. After the connecting rod 4 and the threaded cylinder 11 are threaded together, the position of the spring telescopic cylinder 14 remains unchanged. After the threaded connection is released, the spring inside the spring telescopic cylinder 14 can drive the valve disc body 5 to automatically return to its original position.

[0032] Working principle: At this time, the valve disc body 5 and the adapter ring 7 are sealed and fitted together to ensure the overall sealing of the valve body. When it is necessary to allow flow between the inlet pipe 6 and the outlet pipe 9, the connecting rod 4 is pulled upward. The valve disc body 5 will slowly disengage from the inside of the adapter ring 7. When the trough 10 is no longer blocked by the adapter ring 7, the trough 10 can allow the liquid to flow. At this time, the liquid pressure will not be pressing against the upper surface of the valve disc body 5, so the upward pulling force of the valve disc body 5 will be reduced, resulting in a better overall pulling effect and convenient operation. Then, by rotating the connecting rod 4, the pulled connecting rod 4 can be threaded and fixed inside the threaded cylinder 11.

[0033] When the valve disc body 5 is far from the inside of the adapter ring 7, the trough 10 can transport the liquid delivered by the inlet pipe 6 from the inside of the outlet cylinder 8 and the outlet pipe 9. Then, when the valve disc body 5 is reinstalled into the inside of the adapter ring 7, the connecting plate 17 is first held and rotated, which can drive the top plate 3 and the connecting rod 4 to rotate. At this time, the threaded installation effect between the connecting rod 4 and the threaded cylinder 11 is released. Then, when the threaded installation effect of the connecting rod 4 is released, the elasticity inside the spring telescopic cylinder 14 begins to return to its original position, which can quickly drive the stabilizing ring 12 to move downward, that is, it can drive the valve disc body 5 to move downward and fit into the inside of the adapter ring 7, sealing the entire outlet cylinder 8. The above is the working principle of this utility model.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
