Description

Technical Field

[0001] This utility model relates to the field of plug valve technology, specifically to plug structure and plug valve. Background Technology

[0002] A plug valve is a quick-opening valve that controls opening and closing by rotating a plug with a through hole. It features a simple structure and convenient operation, and is widely used in industries such as petroleum and chemical processing.

[0003] Some existing plug valves rely solely on sealing rings to seal the valve body. As usage time increases and after immersion and corrosion by highly penetrating liquids such as oil, the sealing rings will age and deform, leading to a decrease in the overall sealing performance of the equipment and leakage of liquid from the equipment. In addition, plug valves lack locking when stationary and are easily rotated by external forces, affecting the plug valve's control over the flow of liquid. Utility Model Content

[0004] This utility model provides a plug structure and a plug valve, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: Embodiments of this utility model provide a plug structure and a plug valve, including: a valve body; a sealing device, wherein the sealing device is fixedly installed inside the valve body to achieve multiple protections for the equipment, improve the equipment's sealing performance, and prevent leakage.

[0006] Through the above technical solution, the sealing device further seals the equipment, preventing liquid from seeping out of the equipment due to a decrease in the sealing performance after the sealing gasket ages. At the same time, it locks the roller when the equipment is stationary to prevent accidental activation.

[0007] The sealing device further includes a stopcock, which is rotatably connected to the inside of the valve body. An upper valve stem is welded to the upper surface of the stopcock, and a lower valve stem is welded to the lower surface of the stopcock. Sealing rings are glued to the upper and lower surfaces of the stopcock. A lower sealing block is movably connected to the outer circumference of the lower valve stem. A lower sleeve is slidably connected to the outer circumference of the lower sealing block. A lower spring is fixedly installed at the bottom of the inner cavity of the lower sleeve, and the lower spring is located between the lower sealing block and the lower sleeve. An upper sealing block is slidably connected to the outer circumference of the upper valve stem. An upper sleeve is slidably connected to the outer circumference of the upper sealing block. An upper spring is fixedly installed at the top of the inner cavity of the upper sleeve, and the upper spring is located between the lower sealing block and the lower sleeve. A rotating wheel is fixedly installed on the upper surface of the upper valve stem. The upper valve stem passes through the upper sealing block, the upper sleeve, and the valve body and is connected to the rotating wheel.

[0008] With the above technical solution, when the equipment is in use, the upper spring in the upper sleeve and the lower spring in the lower sleeve are always compressed. Under the reaction of the compression of the upper and lower springs, the upper sealing block and the lower sealing block will be pushed in the direction of the lower valve, so that the upper sealing block and the lower sealing block are in close contact with the valve, improving the sealing performance and preventing liquid leakage.

[0009] Furthermore, damping blocks are slidably connected inside the upper and lower sleeves, and the damping blocks are fixedly connected to the upper and lower sealing blocks respectively.

[0010] Through the above technical solution, the damping block prevents the upper and lower springs from vibrating within the upper and lower sleeves.

[0011] Furthermore, a storage compartment is fixedly installed on the upper surface of the valve body, a movable block is threadedly connected inside the storage compartment, and a telescopic column is fixedly connected to the upper surface of the movable block.

[0012] By using the above technical solution, rotating the telescopic column causes it to drive the moving block to rotate in the storage compartment, thereby raising the telescopic column from the storage compartment and locking it into the gap of the rotating wheel, thus preventing the rotating wheel from rotating.

[0013] Furthermore, a contact block is fixedly installed on the upper surface of the telescopic column.

[0014] The above technical solution prevents wear on the contact block when the rotating wheel contacts the telescopic column.

[0015] Furthermore, a fixing block is fixedly installed on the outer circumference of the storage compartment, and a fixing bolt is threaded inside the fixing block. A screw hole is opened on the outer circumference of the telescopic column to engage with the fixing bolt. The fixing bolt passes through the fixing block and the storage compartment and engages with the screw hole.

[0016] Through the above technical solutions, the fixing blocks and fixing bolts further fix the position of the telescopic column in the storage compartment, making the overall equipment more stable.

[0017] Furthermore, a groove is formed on the upper surface of the contact block, and the groove is oriented in the same direction as the screw hole.

[0018] The above technical solution makes it easier to determine the position of the screw hole and facilitates the fastening of the fixing bolt.

[0019] The beneficial effects of this utility model are: The sealing device improves the overall sealing performance of the equipment. During use, the sealing gasket, upper sealing block, and lower sealing block remain in close contact with the stopcock to prevent liquid leakage. When the equipment is stationary, the rotor is locked to prevent external forces from causing it to move and affecting the performance of the stopcock valve. Attached Figure Description

[0022] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0023] like Figure 1 As shown, the embodiments of this utility model provide a plug structure and a plug valve, including: a valve body 1; a sealing device 2, the sealing device 2 being fixedly installed inside the valve body 1, to achieve multiple protections for the equipment, improve the equipment's sealing performance, and prevent leakage.

[0024] like Figures 1 to 5As shown, the sealing device 2 includes a stopcock 201, which is rotatably connected to the inside of the valve body 1. An upper valve stem 202 is welded to the upper surface of the stopcock 201, and a lower valve stem 203 is welded to the lower surface of the stopcock 201. A sealing ring 204 is glued to the upper and lower surfaces of the stopcock 201. A lower sealing block 205 is slidably connected to the outer circumference of the lower valve stem 203. A lower sleeve 207 is slidably connected to the outer circumference of the lower sealing block 205. A lower spring 206 is fixedly installed at the bottom of the inner cavity of the lower sleeve 207, and the lower spring 206 is located between the lower sealing block 205 and the lower sleeve 207. An upper sealing block 208 is slidably connected to the outer circumference of the upper valve stem 202. The outer circumference of the upper sealing block 208 is slidably connected to... An upper sleeve 210 has an upper spring 209 fixedly installed at the top of its inner cavity. The upper spring 209 is located between the lower sealing block 205 and the lower sleeve 207. A rotating wheel 211 is fixedly installed on the upper surface of the upper valve stem 202. The upper valve stem 202 passes through the upper sealing block 208, the upper sleeve 210, and the valve body 1 and is connected to the rotating wheel 211. During operation, the lower spring 206 and the upper spring 209 are compressed within the lower sleeve 207 and the upper sleeve 210. Under the reaction force of compression, the lower spring 206 and the upper spring 209 push the lower sealing block 205 and the upper sealing block 208 towards the stopcock 201, causing the stopcock 201 to engage with the sealing ring 204, the lower sealing block 205, and the upper sealing block 208. 08. Maintaining tight contact improves the equipment's sealing performance and prevents liquid leakage. A damping block 212 is slidably connected inside the upper sleeve 210 and lower sleeve 207. The damping block 212 is fixedly connected to the upper sealing block 208 and lower sealing block 205 respectively. The damping block 212 increases the friction between the upper sealing block 208 and lower sealing block 205 between the upper sleeve 210 and lower sleeve 207, preventing vibration. A receiving chamber 213 is fixedly installed on the upper surface of the valve body 1. A moving block 214 is threadedly connected inside the receiving chamber 213. A telescopic column 215 is fixedly connected to the upper surface of the moving block 214. When the equipment is stationary, rotating the telescopic column 215 causes the moving block 214 to rotate and rise within the receiving chamber 213. The telescopic column 215 rises from the storage compartment 213 and engages with the gap of the rotating wheel 211, locking the wheel 211 and preventing it from rotating under external force, thus affecting the use of the equipment. A contact block 216 is fixedly installed on the upper surface of the telescopic column 215 to prevent wear between the telescopic column 215 and the rotating wheel 211 when they come into contact. A fixing block 217 is fixedly installed on the outer circumference of the storage compartment 213, and a fixing bolt 218 is threaded inside the fixing block 217. The outer circumference of the telescopic column 215 has a screw hole that engages with the fixing bolt 218. The fixing bolt 218 passes through the fixing block 217 and the storage compartment 213 and engages with the screw hole. Rotating the fixing bolt 218 on the fixing block 217 engages it with the screw hole on the telescopic column 215, fixing the position of the telescopic column 215 on the storage compartment 213 and making the locking more secure. A groove is provided on the upper surface of the contact block 216.The groove is oriented in the same direction as the screw hole, making it easy to determine its position and facilitating the engagement of the 218 fixing bolt.

[0025] During use, the lower spring 206 and the upper spring 209 are compressed within the lower sleeve 207 and the upper sleeve 210. Under the reaction force of this compression, the lower spring 206 and the upper spring 209 push the lower sealing block 205 and the upper sealing block 208 towards the stopcock 201, ensuring that the stopcock 201 maintains tight contact with the sealing ring 204, the lower sealing block 205, and the upper sealing block 208, thus improving the sealing performance of the equipment and preventing liquid leakage. When the equipment is stationary, rotating the telescopic column 215 causes the moving block 214 to rotate and rise within the storage compartment 213. This causes the telescopic column 215 to rise within the storage compartment 213 and engage with the gap in the rotating wheel 211, locking the rotating wheel 211 and preventing external force from causing it to rotate, which would affect the use of the equipment. Simultaneously, rotating the fixing bolt 218 on the fixing block 217 engages the telescopic column 215. The screw holes on the top secure the telescopic column 215 to the storage compartment 213, making the locking more stable.

[0026] The above description is the preferred embodiment of this utility model.
