Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, and in particular to a gate valve that is easy to clean internally. Background Technology

[0002] A gate valve is a type of valve that controls the flow of fluid by the up-and-down movement of a valve disc (or valve core) along the axis of the valve seat sealing surface. Its main function is to cut off or open a fluid passage, and it can also be used to regulate fluid flow. A gate valve typically consists of main components such as a valve body, valve cover, valve core, and valve stem. The valve body and valve cover are generally connected by welding to form a sealed cavity.

[0003] After prolonged use, a lot of dirt will accumulate inside the valve body of the shut-off valve. This is mainly because the fluid may contain various impurities, such as mud, rust, and oil. These impurities will gradually deposit inside the valve body as the fluid passes through the shut-off valve. Since the valve body and valve cover are generally connected by welding, the valve body and valve cover cannot be disassembled. Cleaning personnel cannot directly access key components such as the valve core inside, which makes it very inconvenient to clean the deposits in these parts. Therefore, this utility model provides a shut-off valve that is easy to clean internally. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a shut-off valve that facilitates internal cleaning, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A shut-off valve for easy internal cleaning includes a valve body, a mounting plate fixedly mounted on the surface of the valve body, a mounting groove formed on the side of the mounting plate, a first through hole penetrating the top of the mounting plate, a mounting block slidably connected inside the mounting groove, a second through hole penetrating the top of the mounting block, a first fixing component disposed inside the second through hole, a valve cover fixedly mounted on the opposite side of the mounting block, a valve stem threadedly connected inside the valve cover, a valve core fixedly mounted at the bottom of the valve stem, a rectangular block fixedly mounted at the top of the valve stem, a third through hole penetrating the right side of the rectangular block, a handwheel overlapping the top of the valve stem, a rectangular groove penetrating the top of the handwheel, a fourth through hole penetrating inside the handwheel, and a second fixing component disposed inside the fourth through hole.

[0007] Preferably, the first fixing component includes a first bolt that overlaps inside the second through hole, the first bolt overlapping the first through hole, and a first nut being threaded onto the surface of the first bolt.

[0008] Preferably, the second fixing component includes a second bolt that overlaps inside the fourth through hole, the second bolt overlaps with the third through hole, and a second nut is threaded onto the surface of the second bolt.

[0009] Preferably, a sealing block is fixedly installed at the bottom of the valve cover, and the valve stem is threadedly connected to the sealing block.

[0010] Preferably, the rectangular groove is adapted to the rectangular block, and the rectangular block and the rectangular groove are interlocked.

[0011] Preferably, mounting flanges are fixedly installed on both the left and right sides of the valve body, and mounting holes are provided through the mounting flanges.

[0012] Preferably, the mounting block is adapted to the mounting slot, and there are multiple mounting blocks.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This shut-off valve, which facilitates internal cleaning, allows for easy cleaning of the valve's interior. When cleaning is required, the first fixing component is removed, and the valve cover is rotated, causing the sealing block, mounting block, and other parts to rotate together, separating the mounting block from the mounting groove. The valve cover is then lifted upwards, and the valve cover and other parts are removed from the valve body. The second fixing component is then removed, the handwheel is removed from the valve stem, and the valve stem is removed from the valve cover. Subsequently, the valve body, valve cover, valve stem, valve core, and other parts can be cleaned individually, allowing cleaning personnel direct access to the internal components for more thorough cleaning and effective removal of internal deposits. Furthermore, the coordinated use of the mounting plate, mounting groove, and mounting block allows for faster alignment of the first and second through holes, thus facilitating faster valve cover fixing.

[0020] 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.

[0021] Reference Figure 1-5A shut-off valve for easy internal cleaning includes a valve body 1. A mounting plate 3 is fixedly mounted on the surface of the valve body 1. A mounting groove 4 is formed on the side of the mounting plate 3. A first through hole 5 is formed through the top of the mounting plate 3. A mounting block 6 is slidably connected inside the mounting groove 4, and the mounting block 6 is adapted to the mounting groove 4. Multiple mounting blocks 6 are present. A second through hole 7 is formed through the top of the mounting block 6. A first fixing component is provided inside the second through hole 7. The first fixing component includes a first bolt 8 that overlaps inside the second through hole 7. The first bolt 8 overlaps with the first through hole 5, and a first nut 9 is threaded onto the surface of the first bolt 8. The first fixing component facilitates the fixing of the mounting block 6, thereby facilitating the fixing of the valve cover 10. A valve cover 10 is fixedly mounted on the opposing side of the mounting block 6. A valve stem 12 is threadedly connected inside the valve cover 10. A valve core 13 is fixedly mounted on the bottom of the valve stem 12. A rectangular block 14 is fixedly mounted on the top of the valve stem 12. A third through hole 15 is provided through the right side of the rectangular block 14. A handwheel 16 is attached to the top of the valve stem 12. A rectangular groove 17 is provided through the top of the handwheel 16. The rectangular groove 17 is adapted to the rectangular block 14. The rectangular block 14 and the rectangular groove 17 are inserted into each other. A fourth through hole 18 is provided inside the handwheel 16. A second fixing component is provided inside the fourth through hole 18. The second fixing component includes a second bolt 19 that is attached to the fourth through hole 18. The second bolt 19 is attached to the third through hole 15. A second nut 20 is threaded onto the surface, facilitating the fixing of the handwheel 16 via the second fixing component. A sealing block 11 is fixedly installed at the bottom of the valve cover 10, and the valve stem 12 is threadedly connected to the sealing block 11. The sealing block 11 improves the sealing performance between the valve body 1 and the valve cover 10, as well as between the valve stem 12 and the valve cover 10. Mounting flanges 2 are fixedly installed on both sides of the valve body 1, with mounting holes through them. This allows for easy connection of the valve body 1 to an external water pipe. For this easy-to-clean shut-off valve, when cleaning the inside of the shut-off valve is required, the first fixing component is removed, and the valve cover 10 is rotated to allow the sealing block 11 to be threaded onto the valve cover 10. The components, including block 6, rotate together, causing the mounting block 6 to separate from the mounting groove 4. Then, the valve cover 10 is lifted upwards, and the valve cover 10 and other components are removed from the valve body 1. The second fixing component is then removed, and the handwheel 16 is removed from the valve stem 12. The valve stem 12 is then removed from the valve cover 10. Subsequently, the valve body 1, valve cover 10, valve stem 12, valve core 13, and other components can be cleaned separately, allowing cleaning personnel to directly access the internal components for a more thorough cleaning and effective removal of internal deposits. Furthermore, through the coordinated use of the mounting plate 3, mounting groove 4, and mounting block 6, the alignment of the first through hole 5 and the second through hole 7 can be completed more quickly, thereby enabling the valve cover 10 to be fixed more quickly.

[0022] In use: During operation, the valve body 1 is connected to the external water pipe via the mounting flange 2. For flow, turning the handwheel 16 rotates the rectangular block 14, causing the valve stem 12 to rotate and move upwards, which in turn causes the valve core 13 to rotate and move upwards, moving the valve core 13 to the appropriate position. This allows water to flow through the internal passage of the valve body 1. For closure, turning the handwheel 16 rotates the rectangular block 14, causing the valve stem 12 to rotate and move downwards, which in turn causes the valve core 13 to rotate and move downwards. The movement causes the valve core 13 to seal, thus closing the internal passage of the valve body 1 and preventing water from passing through it. When cleaning the inside of the shut-off valve is required, the valve body 1 is removed from the external water pipe via the mounting flange 2. Then, the first nut 9 is removed from the bottom of the first bolt 8, and the first bolt 8 is pulled out from the first through hole 5 and the second through hole 7. The valve cover 10 is then rotated, causing the sealing block 11, mounting block 6, and other parts to rotate together, separating the mounting block 6 from the mounting groove 4. Finally, the valve cover 10 is lifted upwards, and the valve... Remove parts such as cover 10 from valve body 1. Remove the second nut 20 from the second bolt 19, then pull the second bolt 19 out of the third through hole 15 and the fourth through hole 18. Then remove handwheel 16. Rotate valve stem 12 so that it moves downward while rotating, separating valve stem 12 from valve cover 10. Clean valve body 1, valve cover 10, valve stem 12, valve core 13, etc., separately. After cleaning, install valve stem 12 back into valve cover 10. Then lift rectangular block 14 with rectangular groove 17 on handwheel 16. Insert the second bolt 19 into the third through hole 15 and the fourth through hole 18, and install the second nut 20 on the second bolt 19 in a suitable position to fix the handwheel 16. Then, put the sealing block 11, valve stem 12 and valve core 13 below the valve cover 10 into the valve body 1 until the valve cover 10 contacts the valve body 1. Then rotate the valve cover 10 so that the mounting block 6 is inserted into the mounting groove 4. Then, insert the first bolt 8 into the first through hole 5 and the second through hole 7. Finally, install the first nut 9 on the first bolt 8 in a suitable position to fix the valve cover 10.
