Description

Technical Field

[0001] This utility model relates to the field of sealing device technology, specifically a high-pressure sealing structure for valves. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems. Their varieties and specifications are quite numerous. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. Valves are also classified according to their materials, such as cast iron valves, cast steel valves, stainless steel valves, chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, and non-standard customized valves.

[0003] The current high-pressure sealing structure of valves is not convenient to adjust and change when multiple channels require different flow rates, and the residual liquid inside the pipes is not easy to clean.

[0004] In view of this, we propose a high-pressure sealing structure for valves. Utility Model Content

[0015] 1. In the use of this utility model, when the main body of the high-pressure sealing device of the valve is connected to one end of the valve, it communicates with the inside of the valve. When the material flows into the sealing assembly, one of the drive seats can be activated to retract the internal telescopic baffle to a suitable height, thereby adjusting the flow rate of the liquid in the sealing mounting seat to the required flow rate. When multiple connected pipes require different flow rates, the drive seats can retract the internal telescopic baffles to the required height, allowing the flowing liquid to maintain the required flow rate. When the output is completed, the flow guide plate is pulled out to discharge the liquid remaining in the pipe, facilitating fluid diversion in the pipe and improving the ease of use of the device.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution:

[0025] A high-pressure sealing structure for a valve includes a high-pressure sealing device body 1, a sealing component 2 fixedly installed on the top of the high-pressure sealing device body 1, an inlet pipe 13 fixedly installed at the input end of the high-pressure sealing device body 1, an auxiliary component 3 connected to the input end of the inlet pipe 13, a drive seat 1 21 fixedly installed on the left output end of the sealing component 2, a drive seat 22 fixedly installed on the right output end of the sealing component 2, telescopic baffles 27 slidably connected inside both the drive seat 22 and the drive seat 1 21, a sealing mounting seat 23 fitted at the lower end of the telescopic baffle 27, a drain pipe 26 fixedly installed on the side of the sealing mounting seat 23, a guide pipe 25 fixedly installed below the drain pipe 26, and a guide limiting plate 24 fitted inside the guide pipe 25.

[0026] When the high-pressure sealing device body 1 of the valve is connected to one end of the valve during use, it communicates with the inside of the valve. When the material flows into the sealing assembly, the drive seat 1 21 or drive seat 22 can be activated to retract the internal telescopic baffle 27 to a suitable height, thereby adjusting the liquid flow rate in the sealing mounting seat 23 to the required flow rate. When multiple connected pipes require different flow rates, the drive seat 1 21 and drive seat 22 can retract the internal telescopic baffle 27 to the required height, so that the flowing liquid maintains the required flow rate. When the output is completed, the flow guide plate 24 is pulled out to discharge the liquid remaining in the pipe, which facilitates the diversion of fluid in the pipe and improves the ease of use of the device.

[0027] As a preferred embodiment, the auxiliary component 3 is provided with a mating seat 34 at its rear end. A sealing groove 33 is provided on the inner side of the mating seat 34. A docking ring seat 31 is fixedly installed on the outer side of the mating seat 34. A docking hole 32 is provided inside the docking ring seat.

[0028] It is worth noting that during the use of the high-pressure sealing device body 1 of the valve, the mating ring seats 31 at both ends of the valve are matched with the mating holes 32, and the sealing ring is mated with them, so that the sealing ring is mated with the fitting seat 34, and the sealing groove 33 is sealed to prevent leakage. Then, the mating ring seats 31 are locked with it, so that the mating end is sealed.

[0029] As a preferred embodiment, an assembly plate 14 is fixedly installed at the front end of the main body 1 of the high-pressure sealing device of the valve, and a fixing column 11 is fixedly installed on the side of the main body 1 of the high-pressure sealing device of the valve, with a limiting ring 12 engaged on the side of the fixing column 11.

[0030] In practical use, the assembly plate 14 is engaged with the valve's high-pressure sealing device body 11 by locking the limiting ring 12 in conjunction with the fixing column 1.

[0031] In use, the high-pressure sealing structure for valves of this utility model first connects the main body 1 of the high-pressure sealing device to one end of the valve, thus establishing communication with the valve interior. When the material flows into the sealing assembly, a certain point on either drive seat 1 21 or drive seat 22 can be activated to retract the internal telescopic baffle 27 to a suitable height, thereby adjusting the liquid flow rate within the sealing mounting seat 23 to the required flow rate. When multiple connected pipes require different flow rates, drive seat 1 21 and drive seat 22 can respectively retract the internal telescopic baffle 27. The flow is reduced to the required height so that the flowing liquid retains the required flow rate. When the output is complete, the flow limiting plate 24 is pulled out to discharge the liquid remaining in the pipe, which facilitates the diversion of fluid in the pipe and improves the ease of use of the device. During the use of the high-pressure sealing device body 1 of the valve, the docking ring seats 31 at both ends are matched with the docking holes 32 to dock the sealing ring with it, so that the sealing ring docks with the fitting seat 34 to seal the sealing groove 33 to prevent leakage. Then, the docking ring seat 31 is locked with it to seal the docking end.
