[0002] In many fields, pipeline transportation is a key focus of production line design, serving as an important component of industries such as biopharmaceuticals, food, and chemicals. Pneumatic damper valves, with their advantages of simple structure, short opening and closing time, and safety and reliability, are widely used in pipeline transportation. Pneumatic valves are valves driven by compressed air and can be used to control the flow of various types of fluids, such as steam, various corrosive media, and oils.

[0003] However, when installing existing pneumatic damper valves, the two sides of the valve are mostly connected by flanges. The connection requires that the flange holes on the pneumatic damper valve and the flange holes on the pipeline be aligned. However, it is difficult to ensure that the flange holes are aligned during actual installation, making it difficult to connect the pneumatic damper valve to the pipeline. Furthermore, when the pneumatic damper valve is in the open state, its components are easily worn by the impact of the conveyed medium, reducing the service life of the pneumatic damper valve and hindering its widespread use.

[0004] To address this problem, this application provides an easy-to-install shaft-sealed pneumatic baffle valve. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An easy-to-install shaft-sealed pneumatic baffle valve includes a fixing assembly, a connecting assembly, and a sealing assembly. The fixing assembly includes a baffle valve body and a fixing block, the fixing block being fixedly connected inside the baffle valve body. The connecting assembly is disposed outside the fixing assembly and includes a fixing plate and a rotating groove, the rotating groove being disposed inside the fixing plate. The sealing assembly is disposed inside the fixing assembly and includes a threaded disc, the threaded disc being threadedly installed inside the baffle valve body.

[0008] A further improvement of this utility model is that: a connection hole is provided on the top of the baffle valve body, the fixing plate is fixedly connected to the outside of the baffle valve body, and a sealing gasket is fixedly installed inside the fixing plate.

[0009] A further improvement of this utility model is that a flange is rotatably installed inside the rotating groove, and a top cover is fixedly installed on the top of the baffle valve body.

[0010] A further improvement of this utility model is that: a cylinder is fixedly installed on the top of the upper cover, a movable plate is provided on the top of the fixed block, and a slot is opened on the top of the movable plate.

[0011] A further improvement of this utility model is that: a sleeve is provided inside the slot, the top of the sleeve is movably connected to the bottom of the threaded disc, a connecting rod is fixedly installed at the bottom of the cylinder, the connecting rod is movably installed inside the movable disc, and the connecting rod is movably installed inside the threaded disc.

[0012] A further improvement of this utility model is that a spring is provided at the bottom of the threaded disc, and the bottom of the spring is located at the top of the movable disc.

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] like Figure 1-5 As shown, this utility model provides an easy-to-install shaft seal pneumatic baffle valve, including a fixing component 1, a connecting component 2 and a sealing component 3. The fixing component 1 includes a baffle valve body 10 and a fixing block 13. The fixing block 13 is fixedly connected inside the baffle valve body 10, and a connecting hole 11 is provided on the top of the baffle valve body 10.

[0025] like Figure 2 and Figure 5 As shown, the connecting component 2 is located outside the fixed component 1. The connecting component 2 includes a fixed plate 23 and a rotating groove 21. The rotating groove 21 is located inside the fixed plate 23. The fixed plate 23 is fixedly connected to the outside of the baffle valve body 10. A sealing gasket 22 is fixedly installed inside the fixed plate 23. A flange 20 is rotatably installed inside the rotating groove 21. By setting the fixed plate 23 at the connection of the baffle valve body 10, a rotating groove 21 is formed between the two fixed plates 23. The flange 20 is set in the rotating groove 21, so that the flange 20 can rotate in the rotating groove 21. When connecting the pneumatic baffle valve, if the flange holes are not symmetrical, the flange 20 can be rotated to make them symmetrical. Under the combined action of the fixed plate 23, the rotating groove 21 and the flange 20, it is easy to connect the flange holes. At the same time, when connecting, the bolts will press the flange 20 against the connection between the pneumatic baffle valve and the pipeline, so that the flange 20 is tightly against the sealing gasket 22 in the fixed plate 23, sealing the rotating groove 21 and preventing leakage of the conveying medium.

[0026] like Figure 2-5As shown, the sealing assembly 3 is disposed inside the fixed assembly 1. The sealing assembly 3 includes a threaded disc 31, which is threadedly installed inside the baffle valve body 10. A top cover 30 is fixedly installed on the top of the baffle valve body 10, and a cylinder 12 is fixedly installed on the top of the top cover 30. A movable disc 33 is provided on the top of the fixed block 13, and a slot 34 is opened on the top of the movable disc 33. A sleeve 32 is disposed inside the slot 34, and the top of the sleeve 32 is movably connected to the bottom of the threaded disc 31. By screwing the threaded disc 31 into the baffle valve body 10, the threaded disc 31 presses the sleeve 32 downward, causing the sleeve 32 to press the movable disc 33 and contact the fixed block 13, thus sealing the lower layer of the baffle valve body 10. A connecting rod 36 is fixedly installed at the bottom end of the cylinder 12, and the connecting rod 36 is movably installed inside the movable disc 33 and the threaded disc 31. A spring 38 is installed at the bottom of the valve body 36, and the bottom of the spring 38 is located at the top of the movable disc 33. A secondary sealing plate 37 is fixedly connected to the outside of the connecting rod 36, and a main sealing plate 35 is fixedly installed at the bottom of the connecting rod 36. When the pneumatic baffle valve is closed, the cylinder 12 drives the connecting rod 36 to move downward, so that the main sealing plate 35 contacts the inside of the baffle valve body 10 to achieve a seal. When the pneumatic baffle valve is opened, the cylinder 12 drives the connecting rod 36 to move upward, so that the main sealing plate 35 disengages from the baffle valve body 10, allowing the conveying medium to enter the inside of the baffle valve body 10. At the same time, the upper surface of the secondary sealing plate 37 on the connecting rod 36 contacts the lower surface of the movable disc 33, sealing the lower layer of the baffle valve body 10 and preventing the conveying medium from rushing into the upper layer of the baffle valve body 10 and impacting components such as the spring 38. Through the combined action of the secondary sealing plate 37 and the movable disc 33, the service life of the pneumatic baffle valve is improved.

[0027] The working principle of this easy-to-install shaft seal pneumatic baffle valve will be explained in detail below.

[0028] like Figure 1-5As shown, when using this easy-to-install shaft-sealed pneumatic baffle valve, a fixing plate 23 is installed at the connection of the baffle valve body 10, forming a rotating groove 21 between the two fixing plates 23. A flange 20 is installed in the rotating groove 21, allowing the flange 20 to rotate within the rotating groove 21. This ensures that if the flange holes are misaligned when connecting the pneumatic baffle valve, rotating the flange 20 will align them. Through the combined action of the fixing plate 23, the rotating groove 21, and the flange 20, it is easy to connect the flange holes. Simultaneously, during connection, the bolts will press the flange 20 against the connection between the pneumatic baffle valve and the pipeline, causing the flange 20 to tightly adhere to the sealing gasket 22 in the fixing plate 23, sealing the rotating groove 21 and preventing... To prevent leakage of the conveying medium, when the pneumatic baffle valve is closed, the cylinder 12 drives the connecting rod 36 to move downward, so that the main sealing plate 35 contacts the inside of the baffle valve body 10 to achieve a seal. When the pneumatic baffle valve is opened, the cylinder 12 drives the connecting rod 36 to move upward, so that the main sealing plate 35 disengages from the baffle valve body 10, allowing the conveying medium to enter the inside of the baffle valve body 10. At the same time, the upper surface of the secondary sealing plate 37 on the connecting rod 36 contacts the lower surface of the movable disc 33, sealing the lower layer of the baffle valve body 10 and preventing the conveying medium from rushing into the upper layer of the baffle valve body 10 and impacting components such as the spring 38. Through the combined action of the secondary sealing plate 37 and the movable disc 33, the service life of the pneumatic baffle valve is improved.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
