Description

Technical Field

[0001] This utility model relates to the field of slag removal knife gate valves, specifically a detachable high-pressure bidirectional sealing automatic slag removal knife gate valve. Background Technology

[0002] Applications such as wastewater treatment plants (sedimentation tank outlet, sludge conveying pipelines), mine tailings conveying, river dredging pipelines, power plant fly ash conveying, and food processing (slurry pipelines containing fruit pulp / residue) all use bidirectional sealing automatic slag removal knife gate valves. A large amount of mud, sand, particles, and suspended solids in the medium will adhere to the knife gate sealing surface, valve seat, or slag removal mechanism (such as scraper, guide plate), causing the valve to be stuck when opening and closing, the seal to fail, or the slag removal function to decline. It is necessary to disassemble the valve regularly, clean the internal accumulated impurities, grind the worn knife gate cutting edge, and replace the aged seals.

[0003] However, the slag removal knife gate valve is relatively large. During dismantling, a worker needs to pull the slag removal knife gate valve forcefully before loosening the bolts connecting the valve to the pipeline to prevent it from falling off after the bolts are removed. During installation, workers need to calibrate it multiple times before connecting the slag removal knife gate valve to the pipeline. This installation method is very laborious. Therefore, to address the above problems, a detachable high-pressure bidirectional sealing automatic slag removal knife gate valve is proposed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model proposes a detachable high-pressure bidirectional sealing automatic slag removal gate valve.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a detachable high-pressure bidirectional sealing automatic slag removal knife gate valve, including a slag removal knife gate valve, a limit component is fixedly connected to the side of the frame of the slag removal knife gate valve, a through hole is opened in the middle of the limit component, a pressure bearing component is inserted into the through hole, an extension rod is fixedly connected to the frame of the pressure bearing component, an adjustment component is rotatably connected to the threaded hole of the extension rod, and a rubber sheet is fitted to the frame of the adjustment component;

[0006] Preferably, the limiting component includes: a limiting hole and a sliding block, wherein the sliding block is slidably connected to the groove of the limiting component frame, the limiting component frame has a limiting hole, and the column of the sliding block is slidably connected to the limiting hole;

[0007] Preferably, the sliding block includes: a spring and a sliding column, the block body of the sliding block is fixedly connected to the end of the sliding column, the outer wall of the sliding column is sleeved with a spring, and the column body of the sliding column is slidably connected to a limiting hole;

[0008] Preferably, the pressure-bearing component includes: a plug-in post and a notch, with the notch provided on the upper part of the pressure-bearing component frame and the bottom of the pressure-bearing component frame fixedly connected to the end of the plug-in post;

[0009] Preferably, the adjustment component includes: a connecting handle and an arc-shaped frame, the end of the adjustment component is rotatably connected to the frame of the connecting handle, the end of the connecting handle is fixedly connected to the frame of the arc-shaped frame, and a rubber sheet is fixedly connected to the end face of the arc-shaped frame.

[0010] The advantages of this utility model are:

[0011] 1. This utility model uses a rubber sheet that fits tightly against the outer wall of the pipe. The material of the rubber sheet provides a certain friction between the rubber sheet and the pipe, preventing slippage when the arc-shaped frame directly contacts the pipe. The arc-shaped structure of the arc-shaped frame allows for easy rotation of the slag removal knife gate valve to align with the connected pipe. The insertion of the through hole and the plug, along with the sliding block pressing into the notch groove, secures the pressure-bearing components, preventing loosening when bearing the weight of the slag removal knife gate valve.

[0012] 2. This utility model provides support force for the slag removal gate valve through an adjustment component. This allows the slag removal gate valve to be tightened by the support force provided by the adjustment component after the bolts connecting the slag removal gate valve to the pipeline are loosened, preventing the slag removal gate valve from falling off. At the same time, when installing the slag removal gate valve, adjusting the adjustment component can align the slag removal gate valve with the pipeline, thereby quickly completing the fixing and solving the need for convenient disassembly. Essentially, it is designed to solve the operation and maintenance pain points in scenarios such as high-frequency maintenance, limited space, component damage caused by media / environment, and emergency handling.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a detachable high-pressure bidirectional sealing automatic slag removal knife gate valve, including a slag removal knife gate valve 1. A limit component 2 is fixedly connected to the side of the frame of the slag removal knife gate valve 1. A through hole 7 is opened in the middle of the limit component 2. A pressure bearing component 3 is inserted into the through hole 7. An extension rod 4 is fixedly connected to the frame of the pressure bearing component 3. An adjustment component 5 is rotatably connected to the threaded hole of the extension rod 4. A rubber sheet 6 is fitted to the frame of the adjustment component 5.

[0023] The limiting component 2 includes: a limiting hole 21 and a sliding block 22. The sliding block 22 is slidably connected to the groove of the frame of the limiting component 2. The frame of the limiting component 2 has a limiting hole 21. The column of the sliding block 22 is slidably connected to the limiting hole 21.

[0024] The sliding block 22 includes: a spring 221 and a sliding column 222. The block body of the sliding block 22 is fixedly connected to the end of the sliding column 222. The spring 221 is sleeved on the outer wall of the sliding column 222. The column body of the sliding column 222 is slidably connected to the limiting hole 21.

[0025] The pressure-bearing component 3 includes: a plug-in post 31 and a notch 32. The notch 32 is provided on the upper part of the frame of the pressure-bearing component 3, and the bottom of the frame of the pressure-bearing component 3 is fixedly connected to the end of the plug-in post 31.

[0026] The adjustment component 5 includes: a connecting handle 51 and an arc-shaped frame 52. The end of the adjustment component 5 is rotatably connected to the frame of the connecting handle 51, and the end of the connecting handle 51 is fixedly connected to the frame of the arc-shaped frame 52. A rubber sheet 6 is fixedly connected to the end face of the arc-shaped frame 52.

[0027] Working principle: When installing or removing the slag removal gate valve 1, first press the plug 31 down towards the through hole 7. Because the lower part of the pressure-bearing component 3 is chamfered and has a certain slope, when the pressure-bearing component 3 presses the inclined surface of the sliding block 22, the sliding block 22 will be pressed into the groove opened on the side of the limiting component 2. When the plug 31 is fully inserted into the through hole 7, the sliding block 22 and the notch 32 are at the same level. At this time, the compressed spring 221 will drive the sliding block 22 to pop out, so that the flat part of the sliding block 22 presses into the notch 32, thereby fixing and limiting the pressure-bearing component 3. At this time, the driving adjustment component 5 is rotated because the connecting handle 51 is rotated to connect the end of the adjustment component 5, adjusting... The threaded hole of the extension rod 4 is connected to component 5 by thread. Therefore, by rotating the direction of the adjustment component 5, the height of the arc frame 52 can be adjusted. Since the pressure-bearing component 3 has been fixed in the limiting component 2, by rotating the adjustment component 5 to adjust the arc frame 52, the arc frame 52 drives the rubber sheet 6 to come close to the outer wall of the pipe connected to the slag removal gate valve 1. This allows the adjustment component 5 to provide support for the slag removal gate valve 1. In this way, after loosening the bolts connecting the slag removal gate valve 1 to the pipe, the slag removal gate valve 1 can still be tightened by the support provided by the adjustment component 5, preventing the slag removal gate valve 1 from falling off. At the same time, when installing the slag removal gate valve 1, adjusting the adjustment component 5 can make the slag removal gate valve 1 aligned with the pipe, thereby quickly completing the fixing.

[0028] The rubber sheet 6 is tightly attached to the outer wall of the pipe, and the material of the rubber sheet 6 gives the rubber sheet 6 a certain friction with the pipe, which prevents the arc frame 52 from slipping when it directly contacts the pipe. The arc structure of the arc frame 52 allows the slag removal knife gate valve 1 to be easily rotated and aligned with the connected pipe. The insertion of the through hole 7 and the plug post 31, together with the sliding block 22 pressed into the notch groove 32, can fix the pressure-bearing component 3, so that it will not loosen when bearing the weight of the slag removal knife gate valve 1.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
