Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically a throttling shut-off valve. Background Technology

[0002] Gate valves have the function of regulating flow or pressure. Because gate valves have a relatively small diameter, they are suitable for pipelines or devices with high-temperature and high-pressure media when high precision requirements are not required, so as to cut off the water flow.

[0003] The existing valve body and valve cover are usually installed with multiple sets of bolts. After long-term use, the outer surface of the bolts is prone to rust due to external factors. When disassembling to maintain the valve disc, it is not possible to quickly separate the valve body and valve cover, which reduces the effectiveness of the device.

[0004] Therefore, we propose a throttling shut-off valve to solve the problems mentioned above. Utility Model Content

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. Example

[0024] Please see Figure 1-5 A throttling valve includes a valve body 1. A flow-blocking block 2 is installed at the middle of the inner cavity of the valve body 1. A vent hole is opened at the top of the flow-blocking block 2. A valve cover 3 is provided on the top of the valve body 1. A threaded tube A4 is movably inserted through the top of the valve cover 3. A rocker wheel 9 is fixedly installed at the top of the threaded tube A4. A threaded rod A5 is threadedly connected to the inner cavity of the threaded tube A4. A T-shaped sealing plug 6 is fixedly installed at the bottom end of the threaded rod A5, and the bottom end of the T-shaped sealing plug 6 is inserted into the inner cavity of the vent hole. (The flow can be controlled by rotating the rocker wheel 9.) The threaded tube A4 fixed to the bottom of the rocker wheel 9 rotates, and the threaded rod A5 connected to the inner cavity of the threaded tube A4 can move the T-shaped sealing plug 6 up or down, thereby opening or closing the valve. Fixing boxes 12 are fixedly installed on the left and right sides of the valve body 1 near the top. (The top of the fixing boxes 12 is opened, and the vertical block 13 can pass through the inner cavity of the opening.) The inner cavity of the fixing boxes 12 is equipped with an installation component, and the bottom of the inner cavity of the fixing boxes 12 is equipped with a disassembly component.

[0025] The mounting components include a vertical block 13 fixedly installed on the bottom of the valve cover 3 near the other side, and slots 14 opened on both sides of the vertical block 13 near the bottom. Each slot 14 has a movably inserted block 15 (the end face of the block 15 is arc-shaped). A movable plate 16 is fixedly installed on the side of the block 15 away from it. A compression telescopic rod 17 is fixedly installed on the side of the movable plate 16 away from it near the top and bottom. The ends of the compression telescopic rod 17 are fixedly connected to the inner cavity side wall of the fixed box 12. A compression spring 18 is movably sleeved on the outer periphery of the compression telescopic rod 17, and the two ends of the compression spring 18 are fixedly connected to the adjacent movable plate 16 and the inner cavity side wall of the adjacent fixed box 12, respectively.

[0026] Specifically, when installing the valve cover 3 and the valve body 1, with the cooperation of the installation components, the two vertical blocks 13 can move through the inner cavity of the fixed box 12, and the two locking blocks 15 can be inserted into the inner cavity of the adjacent locking slots 14, which facilitates the installation of the valve cover 3 and the valve body 1 and improves the installation efficiency of the device.

[0027] A sealing gasket 10 is fixedly installed at the bottom of the valve cover 3, and a sealing groove 11 is opened at the top of the valve body 1, with the bottom of the sealing gasket 10 movably inserted into the inner cavity of the sealing groove 11.

[0028] Specifically, by inserting the sealing gasket 10 into the inner cavity of the sealing groove 11, the sealing performance between the valve cover 3 and the valve body 1 can be improved.

[0029] L-shaped connecting blocks 7 are fixedly installed on the top of the T-shaped sealing plug 6 near both sides. Limiting telescopic rods 8 are fixedly installed on the top of the L-shaped connecting blocks 7. The top of the limiting telescopic rods 8 are fixedly connected to the valve cover 3.

[0030] Specifically, by setting the L-shaped connecting block 7 and the limiting telescopic rod 8, the movement of the T-shaped sealing plug 6 can be limited. Example

[0031] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 4 and Figure 5 The disassembly assembly includes a rack plate 19 fixedly installed on two adjacent movable plates 16 and a rotating toothed roller 20 meshing on opposite sides of the rack plate 19. A vertical rod 21 is fixedly installed at the bottom of the rotating toothed roller 20, and the bottom end of the vertical rod 21 moves through the bottom of the inner cavity of the fixed box 12 and is fixedly installed with a drive handle 22.

[0032] Specifically, when separating the valve cover 3 from the valve body 1, with the cooperation of the disassembly assembly, the T-shaped insert 23 can be moved away from the inner cavity of the adjacent limiting hole, and the drive handle 22 can be driven to rotate the vertical rod 21 fixed on the drive handle 22. The two movable plates 16 can be moved to the opposite side by the drive handle 22 fixed on the vertical rod 21, which facilitates the disassembly and separation of the two.

[0033] The outer periphery of the vertical rod 21 is provided with several limiting holes, and the limiting holes are arranged in a circular array with the bottom of the drive handle 22 as the center.

[0034] A T-shaped insert rod 23 is movably inserted into the inner cavity of the adjacent limiting hole. A threaded rod B26 is fixedly installed on one side of the T-shaped insert rod 23. A threaded tube B25 is threadedly connected to the outer circumference of the threaded rod B26. A hexagonal nut is fixedly installed at one end of the threaded tube B25. A vertical plate 24 is rotatably connected to the outer circumference of the threaded tube B25. The top of the vertical plate 24 is fixedly connected to the fixed box 12.

[0035] Specifically, by rotating the hexagonal nut, the threaded tube B25 fixed on the hexagonal nut can be rotated, thereby causing the threaded rod B26, which is threaded into the inner cavity of the threaded tube B25, to push the T-shaped insert 23 to the other side under the limit of the limit rod 27, and then insert it into the inner cavity of the upper limit hole of the drive handle 22, which can prevent external personnel from accidentally disconnecting the connection between the valve cover 3 and the valve body 1.

[0036] A limiting rod 27 is fixedly installed on the top of the T-shaped insert 23, and one end of the limiting rod 27 moves through the inner cavity of the upright plate 24.

[0037] Specifically, the T-shaped insert 23 can be limited when it moves by setting the limit rod 27.

[0038] Working Principle: When using this invention, if the valve body 1 and valve cover 3 need to be installed, the two vertical blocks 13 fixed to the bottom of the valve cover 3 pass through the inner cavity of the adjacent fixing box 12. Since the bottom of the vertical blocks 13 is arc-shaped, and the end faces of the two locking blocks 15 are also arc-shaped, when the vertical blocks 13 move through the inner cavity of the adjacent fixing box 12, the locking blocks 15 can be moved into the inner cavity of the adjacent locking slot 14, which is convenient for installation. Then, by rotating the hexagonal nut, the threaded tube B25 fixed on the hexagonal nut can be rotated, thereby allowing the threaded connection in the inner cavity of the threaded tube B25 to be made. The B26 pushes the T-shaped insert 23 to move to the other side under the limit of the limit rod 27, so that it can be inserted into the inner cavity of the upper limit hole of the drive handle 22. This can prevent external personnel from accidentally disconnecting the connection between the valve cover 3 and the valve body 1. When separating the valve cover 3 and the valve body 1, with the cooperation of the disassembly components, the T-shaped insert 23 can be moved away from the inner cavity of the adjacent limit hole, and the drive handle 22 can be driven to rotate the vertical rod 21 fixed on the drive handle 22. The drive handle 22 fixed on the vertical rod 21 can move the two movable plates 16 to the opposite side, which is convenient for disassembly and separation.
