Technical Field
[0001] The utility model relates to the technical field of valve connection equipment, in particular to a valve connection device for preventing leakage. Background Art
[0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. It is a control component in a pipeline fluid delivery system. It is used to change the passage section and the flow direction of the medium. It has functions such as diversion, cutoff, throttling, check, diversion, or overflow pressure relief. With the progress of society and the development of science and technology, various power plants have emerged. Some valves are needed in some installation locations to change the passage section and the flow direction of the medium. Valves and pipelines work together to form a circulation mechanism. However, at the current stage, the seals at the valve connection mechanism will age over time, resulting in poor sealing effect. In severe cases, it will cause leakage risks. To this end, we propose a valve connection device that prevents leakage. Utility Model Content

DETAILED DESCRIPTION
[0016] 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.
[0017] See also Figure 1-3 The utility model provides a technical solution: a valve connection device for preventing leakage, comprising a main pipeline 1, a connecting ring 11 is provided at the end of the main pipeline 1, the connecting ring 11 is clamped in a sleeve 14, the sleeve 14 is installed in a mounting groove 19 of a connecting cover 18, a sealing ring 22 is provided on the outer side of the connecting cover 18, a reducer 23 is provided on the side of the sealing ring 22 close to the connecting cover 18, and the reducer 23 is correspondingly clamped in the connecting groove 24.
[0018] By setting a connecting ring 11 at the connecting end of the main pipeline 1, and through the cooperation of the sleeve 14, the valve connecting pipeline can be stably connected, and a double sealing mechanism is formed under the cooperation of the sleeve 14 and the connecting cover 18, which effectively improves the anti-leakage performance of the valve connecting pipeline connection.
[0019] In the above solution, the end of the main pipeline 1 is connected to the connecting pipe 13 through the flange 12. Adjacent flanges 12 are sealed by gaskets and connected by screws.
[0020] In the above scheme, the connecting ring 11 is clamped in the cylindrical hole in the sleeve 14, and the side wall of the sleeve 14 is provided with an overflow groove 15. Under the action of the internal seal, if there is water leakage at the interface, water under pressure reaches and fills the overflow groove 15. By utilizing the special structure of the sleeve 14, the outer wall of the sleeve 14 can be closely attached to the inner wall of the connecting cover 18 under the action of water flow pressure.
[0021] In the above solution, a block 16 is provided on the outside of the main pipe 1, and the block 16 is correspondingly engaged in the slot 17 provided on the inside of the connection cover 18. The cooperation between the block 16 and the slot 17 improves the installation stability of the connection cover 18.
[0022] In the above solution, an elastic block 2 is arranged outside the sleeve 14, and the elastic block 2 is correspondingly engaged in the limiting hole 21 opened inside the connection cover 18. Specifically, the corners of the elastic block 2 are processed with arc chamfers, and the elastic block 2 can be made of soft materials such as silicone rubber. When the connection cover 18 is engaged with the sleeve 14, the elastic block 2 is gradually engaged in the limiting hole 21 under pressure.
[0023] In the above solution, the connection cover 18 is semicircular, and the end of the connection cover 18 is provided with an ear seat 26, and adjacent ear seats 26 are connected by bolts 27. The detachable connection method can facilitate the use of the connection cover 28 and the main pipeline 1.
[0024] In the above scheme, the sealing ring 22 is threadedly matched with the main pipe 1 through the threaded portion 25 provided on the inner side. Correspondingly, the outer side of the main pipe 1 is provided with an external thread that matches with it, and the threaded portion 25 is threadedly matched with the external thread by gradually rotating the sealing ring 22. In this process, the reducer 23 gradually enters the interior of the connection groove 24 for clamping, thereby ensuring the sealing connectivity of the equipment.
[0025] By arranging a sealing ring 22 on the outer side of the connection cover 18, the connection between the sealing ring 22 and the connection cover 18 is made tighter with the cooperation of the reducer 23 and the connection groove 24, thereby further improving the sealing performance at the interface.
[0026] Working principle:
[0027] This anti-leakage valve connection device, by setting a connection ring 11 at the connection end of the main pipeline 1, and by the cooperation of the sleeve 14, the valve connection pipeline can be stably connected, and a double sealing mechanism is formed under the cooperation of the sleeve 14 and the connection cover 18, which effectively improves the anti-leakage performance of the valve connection pipeline connection. The side wall of the sleeve 14 is provided with an overflow groove 15. Under the action of the internal seal, if there is a water leak at the interface, the water reaches and fills the overflow groove 15 under the action of the pressure. By using the special structure of the sleeve 14, the outer wall of the sleeve 14 can be close to the inner wall of the connection cover 18 under the action of the water flow pressure, and the threaded part 25 is screwed with the external thread by gradually rotating the sealing ring 22. In this process, the reducer 23 gradually enters the interior of the connection groove 24 for clamping, thereby ensuring the sealing connectivity of the equipment. By setting the sealing ring 22 on the outside of the connection cover 18, the reducer 23 and the connection groove 24 make the connection between the sealing ring 22 and the connection cover 18 tighter.
