[0002] Grooved butterfly valves are a common type of valve, primarily used in piping systems to control fluid flow. Their core structure includes a rotatable valve disc, typically circular, which is rotated to regulate or cut off fluid flow. Grooved butterfly valves are widely used in water supply, drainage, fire protection systems, HVAC, and many other industries.

[0003] Grooved butterfly valves can adjust their opening degree as needed to regulate flow and are suitable for various fluid control requirements. However, as the valve plate inside the butterfly valve rotates, the sealing ring will wear down over time, leading to leakage. Utility Model Content

[0004] The purpose of this utility model is to provide a grooved butterfly valve with high-efficiency sealing, so as to solve the problem that the inner valve plate of the butterfly valve will wear down the sealing ring as the valve plate rotates during use, thus causing leakage. This is because the grooved butterfly valve can adjust the opening degree as needed to achieve flow regulation and is suitable for various fluid control needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency sealing grooved butterfly valve, comprising a butterfly valve body, a valve plate disposed inside the butterfly valve body, and a sealing assembly disposed on the outer periphery of the butterfly valve body.

[0022] Reference Figures 1 to 5In this embodiment of the present invention, a highly efficient sealing grooved butterfly valve includes a butterfly valve body 1, a valve plate 3 is provided inside the butterfly valve body 1, and a sealing component 2 is provided on the outer periphery of the butterfly valve body 1. The sealing component 2 includes a sealing groove 27 opened on the outer periphery of the valve plate 3 and an inflatable sealing ring 29 provided inside the sealing groove 27. An installation base 21 is fixedly installed on the outer periphery of the butterfly valve body 1, and an air pump 22 for inflating or deflating the inflatable sealing ring 29 is fixedly installed at the top of the installation base 21. An air inlet pipe 23 for easy air intake is fixedly installed at the top of the air pump 22. An air inflation pipe 24 for inflation is fixedly installed at one end of the air pump 22. A connecting hose 26 is fixedly installed at one end of the air inflation pipe 24, and one end of the connecting hose 26 passes through the butterfly valve body 1 and is connected to the side of the inflatable sealing ring 29. An adjustment switch 25 for adjusting the inflation mode is provided at one end of the air pump 22.

[0023] With the above settings: the inflatable sealing ring 29 is an elastic hollow sealing ring. The air pump 22 can completely fill the inflatable sealing ring 29 inside the sealing groove 27. At the same time, the air pump 22 can be switched to the deflation mode by adjusting the switch 25. At this time, the air pump 22 causes the inflatable sealing ring 29 to undergo elastic deformation by evacuating air. As the air pressure inside the inflatable sealing ring 29 moves from the low air pressure end to the high air pressure end, the inflatable sealing ring 29 will undergo elastic deformation, which reduces the wear of the sealing ring caused by the valve plate 3 when it rotates and increases the sealing performance.

[0024] Reference Figures 1 to 5 One end of the air pump 22 is equipped with a portable power supply 210 for easy power supply, and a protective net 211 is fixedly installed inside the air inlet pipe 23 to reduce the entry of external dust.

[0025] With the above settings: by setting a protective net 211 inside the air intake pipe 23, the air pump 22 can reduce the entry of dust from the outside air during the air pumping process, and reduce the possibility of dust entering the air pump 22 and causing blockage of the connecting hose 26.

[0026] Reference Figures 1 to 5 Inside the butterfly valve body 1, there is a valve stem 4 that drives the valve plate 3 to rotate. A fixing plate 5 that is fixedly installed on the outer periphery of the valve stem 4 and fixedly installed on the valve plate 3 is symmetrically installed. The valve stem 4 passes through the butterfly valve body 1 and a rotator 6 is fixedly installed at the top of the outside. A handwheel 7 is rotatably connected to one end of the rotator 6.

[0027] Reference Figures 1 to 5The butterfly valve body 1 has an installation assembly 8 at one end for easy installation. The installation assembly 8 includes an installation flange 81 fixedly installed at one end of the butterfly valve body 1 and an installation flange 82 fixedly installed at the other end of the butterfly valve body 1 opposite to the installation flange 81. An installation disc 89 is rotatably connected to one end of the installation flange 81. An L-shaped locking block 85 is evenly and fixedly installed around one end of the installation disc 89 for fixing. A rotating groove 86 is evenly and evenly opened around one end of the installation flange 82 to engage with the L-shaped locking block 85. An insertion groove 88 is opened at the top of the installation disc 89, and a handle 87 is inserted into the top of the insertion groove 88 to drive the installation disc 89 to rotate. An elastic sealing ring 84 is fixedly installed at one end of the installation flange 81 to increase the sealing performance. A sealing groove 83 adapted to the elastic sealing ring 84 is opened at one end of the installation flange 82.

[0028] The working principle of this utility model is as follows: When installing the butterfly valve body 1, the L-shaped locking block 85 at one end of the mounting plate 89 of the mounting flange 1 is inserted into the rotating groove 86 at one end of the mounting flange 2 82 of the other butterfly valve body 1. Then, the handle 87 is inserted into the insertion groove 88 at the top of the mounting plate 89. At this time, the operator rotates the handle 87 to drive the mounting plate 89 to rotate. At this time, the L-shaped locking block 85 rotates inside the rotating groove 86, completing the quick installation of the butterfly valve body 1. The elastic sealing ring 84 and the sealing groove 3 83 can increase the sealing performance of the installation. The installation component 8 can reduce the cumbersome installation of the mounting flange by screws and bolts, and increase the convenience and speed of the butterfly valve body 1 installation. When the installation is completed, the handle 87 can be pulled out of the insertion groove 88. When it is necessary to rotate the valve plate 3.
