Description

Technical Field

[0001] This utility model relates to the field of pipeline flow control technology, specifically to a corrosion-resistant material conveying pipeline flow control device. Background Technology

[0002] In industrial production, the flow control device of material conveying pipelines is a key component to ensure the stable operation of the production process.

[0003] Traditional flow control devices, such as valves, typically use corrosion-resistant materials when dealing with corrosive materials. However, the seals within these valves wear down as the valve disc rotates, and the corrosive medium further accelerates corrosion of the seals. Replacing the seals in traditional valves is also slow. Therefore, a corrosion-resistant flow control device for material conveying pipelines is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a corrosion-resistant material conveying pipeline flow control device that can solve the problems mentioned in the background.

[0005] To achieve the above objectives, the present invention proposes a corrosion-resistant material conveying pipeline flow control device, comprising a flow valve, a cover plate detachably connected to the flow valve by bolts, an adjusting mechanism on the flow valve, and a sealing element embedded in the flow valve. The adjusting mechanism includes:

[0006] Seal 2, the top of which is detachably connected to a sleeve rod, and the top of which is fixedly connected to a threaded block;

[0007] A screw, which is threadedly connected to a threaded block, and a handle is fixedly connected to the top of the screw;

[0008] A guide rod is fixedly connected to the top of the cover plate.

[0009] Preferably, the guide rod passes through the threaded block and is slidably connected to the threaded block. A limit block is fixedly connected to the outer wall of the guide rod. By rotating the handle, the screw is driven to rotate, and under the action of the guide rod, the threaded block drives the sleeve rod to move upward, thereby moving the second seal away from the first seal. This vertical lifting and lowering reduces the wear of the second seal and the first seal and improves the service life of the seal.

[0010] Preferably, a connecting block is fixedly connected to the top of the second sealing element, and the connecting block has a positioning port and an insertion port.

[0011] Preferably, the second seal can descend to fit tightly against the first seal.

[0012] Preferably, a positioning block is fixedly connected to the bottom of the sleeve rod. The positioning block matches the positioning port. After the positioning block is inserted into the positioning port, it can be fixed by a pin. In this way, the second seal can be quickly disassembled and replaced. After the cover plate is removed, the first seal can also be disassembled and replaced, thereby improving the replacement rate of the sealing components.

[0013] Preferably, the outer wall of the second seal is provided with an opening, and the bottom of the second seal is rotatably connected to a rotating shaft. A blade is fixedly connected to the outer wall of the rotating shaft. By using the opening, the material passes through the opening and impacts the rotating blade during the up-and-down movement of the second seal, thereby reducing the material adhering to the second seal.

[0014] Preferably, the blade is in contact with the inner surface of the second seal.

[0015] This utility model provides a corrosion-resistant material conveying pipeline flow control device. It features the following:

[0016] Beneficial effects:

[0017] (1) The corrosion-resistant material conveying pipeline flow control device drives the screw to rotate by turning the handle. Under the limiting action of the guide rod, the threaded block drives the second sealing element to rise and fall in the vertical direction, so as to achieve the contact or separation with the first sealing element. This vertical movement mode avoids the friction loss of the sealing surface caused by traditional horizontal sliding, reduces the risk of wear and deformation of the sealing components caused by friction, can effectively extend the service life of the sealing components, reduce the hidden danger of equipment leakage, and reduce the frequency of downtime maintenance due to seal failure.

[0018] (2) The sealing element of the corrosion-resistant material conveying pipeline flow control device is precisely matched with the positioning port of the positioning block and the connecting block, and fixed by the pin. Combined with the bolt connection structure of the cover plate and the flow valve, the sealing element can be quickly disassembled and assembled, thus improving work efficiency.

[0019] (3) The corrosion-resistant material conveying pipeline flow control device uses the port so that when the sealing element 2 moves up and down, the material passes through the port and impacts the blade rotation, reducing the material adhering to the sealing element 2, thereby reducing the corrosion of the sealing element 2 by the material and extending the service life of the sealing element 2.

[0029] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figures 1-5 This utility model proposes a flow control device for a corrosion-resistant material conveying pipeline, including a flow valve 1, a cover plate 2 detachably connected to the flow valve 1 by bolts, an adjustment mechanism 3 provided on the flow valve 1, and a sealing element 4 embedded in the flow valve 1.

[0033] In this embodiment of the utility model, the adjusting mechanism 3 includes a second sealing element 31, a screw 34, and a guide rod 36. The second sealing element 31 descends to fit tightly against the first sealing element 4. A sleeve rod 32 is detachably connected to the top of the second sealing element 31, and a threaded block 33 is fixedly connected to the top of the sleeve rod 32. The screw 34 is threadedly connected to the threaded block 33, and a handle 35 is fixedly connected to the top of the screw 34. The guide rod 36 is fixedly connected to the top of the cover plate 2, passes through the threaded block 33, and is slidably connected to the threaded block 33. A handle 35 is fixedly connected to the outer wall of the guide rod 36. The limiting block 37, by rotating the handle 35, drives the screw 34 to rotate, and then, under the action of the guide rod 36, the threaded block 33 drives the sleeve rod 32 to move upward, thereby moving the second seal 31 away from the first seal 4. Conversely, the second seal 31 can abut against the first seal 4. This vertical movement mode avoids the friction loss of the sealing surface caused by traditional horizontal sliding, reduces the risk of wear and deformation of the sealing components caused by friction, can effectively extend the service life of the sealing components, reduce the risk of equipment leakage, and reduce the frequency of downtime maintenance due to seal failure.

[0034] Furthermore, a connecting block 311 is fixedly connected to the top of the second seal 31. The connecting block 311 has a positioning port 312 and a socket 313. A positioning block 321 is fixedly connected to the bottom of the sleeve rod 32. The positioning block 321 matches the positioning port 312. After the positioning block 321 is inserted into the positioning port 312, it can be fixed by the pin 322. Through the precise cooperation between the positioning block 321 and the positioning port 312 of the connecting block 311, and the fixing by the pin 322, combined with the bolt connection structure between the cover plate 2 and the flow valve 1, the second seal 31 can be quickly disassembled and replaced, improving work efficiency.

[0035] Example 2

[0036] Based on Example 1, please refer to Figure 6 The outer wall of the second seal 31 has an opening 314. The bottom of the second seal 31 is rotatably connected to a rotating shaft 315. A blade 316 is fixedly connected to the outer wall of the rotating shaft 315. The blade 316 is in contact with the inner surface of the second seal 31. During the up and down movement of the second seal 31, the conveyed material passes through the opening 314 and impacts the blade 316 to rotate, reducing the material adhering to the second seal 31, thereby reducing the corrosion of the second seal 31 by the material and extending the service life of the second seal 31.

[0037] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0038] In use, by turning the handle 35, the screw 34 is driven to rotate, and under the action of the guide rod 36, the threaded block 33 drives the sleeve rod 32 to move upward, thereby moving the second seal 31 away from the first seal 4. Conversely, the second seal 31 can be pressed against the first seal 4. During the process of the second seal 31 moving away from the first seal 4, the flow rate can be adjusted. When it is necessary to replace the second seal 31 and the first seal 4, the first seal 4 can be replaced by removing the cover plate 2 and the bolt, and then taking out the adjustment mechanism 3. The second seal 31 can be removed by using the pin 322. The positioning block 321 and the positioning port 312 of the connecting block 311 are precisely matched to achieve quick disassembly and replacement of the second seal 31.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
