Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a novel anti-fouling sealing reversing device. Background Art

[0002] A valve is a pipeline accessory used to open and close pipelines, control flow direction, regulate and control the transport of media. It is a device that allows the media in pipes and equipment to flow or stop and control its flow rate.

[0003] Publication No. CN218094500U discloses a multi-seal valve. This patent releases the limit on the adjusting column by loosening the bolts, allowing the adjusting column to rotate. The connecting rod is rotated to move the limit column to the inside of the adjusting rod. The adjusting rod is pulled upward so that its end exceeds the height of the valve handle. The connecting rod is then rotated to move the limit column to the outside of the adjusting rod. The limit column is aligned with the fixing hole. The connecting rod spring is loosened to drive the adjusting rod to move downward, so that the limit column is inserted into the fixing hole to position the valve handle. This prevents the valve handle from being rotated due to external objects touching the valve handle when the multi-seal valve body is not in use. The bolts are tightened to prevent the adjusting column from rotating, thereby effectively improving the stability of the limit column inserted in the fixing hole. However, this patent still has the following problems during actual use:

[0004] The valve handle is positioned to prevent external objects from touching the valve handle and causing the valve handle to rotate when the multi-seal valve body is not in use. The bolt is tightened so that the adjusting column cannot rotate, thereby effectively improving the stability of the limit column inserted in the fixing hole. However, in actual use, if the valve handle is limited after being rotated, multiple steps are required to limit the valve handle, which is cumbersome and inconvenient for staff to use.

[0005] A novel anti-fouling seal reversing device is proposed to solve the above problems. Utility Model Content

However, in actual use, if the valve handle is limited after being rotated, multiple steps are required to limit the valve handle, the operation is relatively cumbersome, and it is inconvenient for staff to use.

[0007] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions: a novel anti-fouling seal reversing device, comprising a valve body;

[0008] A valve cover is fixedly installed on the top of the valve body;

[0009] Also includes:

[0010] A compression nut is threadedly connected to the upper inner portion of the valve cover, and a valve stem is threadedly connected to the inner portion of the compression nut, and a valve head is fixedly mounted on the bottom of the valve stem, and a hand wheel is fixedly mounted on the top of the valve stem, and positioning components are symmetrically arranged on both sides of the hand wheel;

[0011] The positioning assembly includes mounting blocks symmetrically mounted on both sides of the handwheel, and a movable rod is slidably connected inside the mounting blocks, and a fixed block is fixedly mounted on the top of the movable rod, and a J-shaped rod is fixedly mounted on one side of the bottom of the fixed block, and the J-shaped rod is slidably connected to the handwheel;

[0012] Wherein, a telescopic spring is sleeved on the lower part of the outer portion of the movable rod, and one end of the telescopic spring is fixedly connected to the mounting block, and the other end of the telescopic spring is fixedly mounted with a connecting block, and the connecting block is fixedly connected to the movable rod.

[0013] Preferably, a limiting ring is provided below the handwheel, and a plurality of positioning holes are opened through the top of the limiting ring, and the J-shaped rod is adapted to be connected with the positioning hole, and a plurality of fixing rods are fixedly installed on the inner side of the limiting ring, and a mounting ring is fixedly installed on one end of the plurality of fixing rods away from the limiting ring.

[0014] Preferably, a fixing ring is fixedly mounted on the upper portion of the exterior of the valve stem, an annular groove is provided on the inner side of the mounting ring, and the fixing ring is slidably connected to the annular groove.

[0015] Preferably, positioning blocks are symmetrically installed on the upper part of the exterior of the valve cover, and support rods are slidably connected to the interior of the positioning blocks, and both support rods are fixedly connected to the limiting ring.

[0016] Preferably, a support block is fixedly mounted on one side of the two mounting blocks that are away from each other, and the top of the support block is rotatably connected to a limiting rod, and the limiting block is fixedly mounted on one side of the limiting rod.

[0017] Preferably, a limiting groove is provided on one side of the top of the fixing block, and the limiting block is engaged with the limiting groove.

[0018] Preferably, the two limiting rods are L-shaped.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: the novel anti-fouling seal reversing device has positioning components symmetrically arranged on both sides of the handwheel, so that after the valve stem is rotated, the fixing block can be pressed to release the limit of the handwheel, and then the fixing block can be released to position the handwheel, which is convenient for the staff to operate the handwheel to rotate, and the handwheel can be positioned after it is rotated, thereby avoiding accidental touch causing the valve stem to rotate, thereby improving convenience and practicality. The specific contents are as follows:

[0020] 1. Positioning components are symmetrically arranged on both sides of the handwheel. By turning the handwheel, the valve stem can be driven down, so that the valve head seals the inside of the valve body, which has a good sealing effect and prevents dirt from flowing back when the valve body is closed. Before turning the handwheel, the two fixed blocks can be pressed to drive the J-shaped rod to move down, and the movable rod can be driven to slide on the mounting block, so that the telescopic spring can be stretched through the connecting block. After the J-shaped rod moves, it can be disengaged from the positioning hole on the limit ring, thereby making the J-shaped rod lose its limit and the handwheel lose its limit. The handwheel rotation can drive the valve stem to move up and down. During the rotation of the valve stem, the fixed ring can rotate in the annular groove on the inner side of the mounting ring. The up and down movement of the valve stem can drive the mounting ring to move up and down through the cooperation of the fixed ring and the annular groove. When the hand wheel stops rotating, one end of the J-shaped rod is aligned with the corresponding positioning hole. Then the fixing block can be loosened. Under the action of the telescopic spring, the J-shaped rod can be driven to move upward so that one end of the J-shaped rod can be inserted into the positioning hole, thereby limiting the hand wheel and preventing accidental rotation of the hand wheel. The positioning assembly allows the valve stem to be rotated and the fixing block can be pressed to release the hand wheel from the limit. After that, the fixing block can be loosened so that the hand wheel can be positioned, which is convenient for the staff to operate the hand wheel rotation and can be positioned after the hand wheel is rotated to avoid accidental touch causing the valve stem to rotate, thereby improving convenience and practicality.

[0021] 2. When the handwheel is rotated a large number of times, the limit rod can be rotated after pressing the fixed block. After the limit rod is rotated on the support block, one end can be rotated above the fixed block to block the fixed block. Then the upper limit block of the limit rod can be aligned with the upper limit slot of the fixed block. After that, the fixed block is released and the limit rod is moved up under the action of the telescopic spring so that the limit block is engaged with the limit slot, thereby limiting the fixed block and preventing the fixed block and the J-shaped rod from resetting. When the handwheel is rotated a large number of times, it is possible to avoid pressing the fixed block uniformly, so that the fixed block can be limited after moving, thereby improving convenience.

The positioning component 2 allows the valve stem 103 to be rotated, and then the fixed block 203 can be pressed to release the limit of the handwheel 105. Then, the fixed block 203 can be released to position the handwheel 105, which is convenient for the staff to operate the handwheel 105 to rotate, and the handwheel 105 can be positioned after it is rotated to avoid accidental touch causing the valve stem 103 to rotate, thereby improving convenience and practicality.

[0030] A limiting ring 207 is provided below the handwheel 105, and a plurality of positioning holes 208 are provided through the top of the limiting ring 207, and the J-shaped rod 206 is adapted to be connected with the positioning hole 208, and a plurality of fixing rods 210 are fixedly installed on the inner side of the limiting ring 207, and a mounting ring 209 is fixedly installed on one end of the plurality of fixing rods 210 away from the limiting ring 207, so that the handwheel 105 can be limited, a fixing ring 212 is fixedly installed on the outer upper part of the valve stem 103, and an annular groove 211 is provided on the inner side of the mounting ring 209, and the fixing ring 212 is slidably connected with the annular groove 211, so that the valve stem 103 can move up and down to drive the mounting ring 209 to move, and a positioning block 21 is symmetrically installed on the outer upper part of the valve cover 101. 4, and the internal sliding connection of the positioning block 214 is connected to the support rod 213, and the two support rods 213 are fixedly connected to the limiting ring 207 to limit the movement of the mounting ring 209, and the two mounting blocks 201 are fixedly installed with support blocks 215 on the side away from each other, and the top of the support block 215 is rotatably connected to the limiting rod 216, and a limiting block 217 is fixedly installed on one side of the limiting rod 216 to facilitate limiting the fixing block 203. A limiting groove 218 is provided on one side of the top of the fixing block 203, and the limiting block 217 is engaged with the limiting groove 218, so that the fixing block 203 can be limited after moving. The two limiting rods 216 are L-shaped, so that the limiting rods 216 can block the fixing block 203 after rotating.

[0031] Working principle: Before using this new anti-fouling seal reverse device, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5As shown, positioning components 2 are symmetrically provided on both sides of the handwheel 105. By rotating the handwheel 105, the valve stem 103 can be driven to descend, so that the valve head 104 can seal the inside of the valve body 1, which has a good sealing effect, so that dirt can be prevented from flowing back when the valve body 1 is closed. Before the handwheel 105 is rotated, the two fixing blocks 203 can be pressed to drive the J-shaped rod 206 to move downward, and the movable rod 202 can be driven to slide on the mounting block 201, so that the telescopic spring 204 can be stretched by the connecting block 205. After the J-shaped rod 206 moves, it can be disengaged from the positioning hole 208 on the limiting ring 207, thereby making the J-shaped rod 206 lose its limit, and the handwheel 105 loses its limit. The rotation of the handwheel 105 can drive the valve stem 103 to move up and down. During the rotation process of the valve stem 103, the fixing ring 212 can rotate in the annular groove 211 inside the mounting ring 209. The up and down movement of the valve stem 103 can drive the mounting ring 209 to move up and down through the cooperation of the fixing ring 212 and the annular groove 211 09 moves up and down, and the mounting ring 209 drives the support rod 213 to slide on the positioning block 214 to support and limit. After the valve stem 103 moves, the valve head 104 moves, and the valve body 1 can be opened and closed. After the handwheel 105 stops rotating, one end of the J-shaped rod 206 is aligned with the corresponding positioning hole 208. Then the fixing block 203 can be loosened, and the J-shaped rod 206 can be driven to move up under the action of the telescopic spring 204, so that one end of the J-shaped rod 206 can be inserted into the positioning hole 208, thereby limiting the handwheel 105 to prevent the handwheel 105 from rotating accidentally. Through the positioning assembly 2, the valve stem 103 can be rotated, and the fixing block 203 can be pressed to release the handwheel 105 from the limit. Then, the fixing block 203 can be loosened to allow the handwheel 105 to be positioned, which is convenient for the staff to operate the handwheel 105 to rotate, and the handwheel 105 can be positioned after it is rotated, to prevent the valve stem 103 from rotating due to accidental touch, thereby improving convenience and practicality.

[0032] When the hand wheel 105 is rotated a large number of times, the limit rod 216 can be rotated after pressing the fixed block 203. After the limit rod 216 is rotated on the support block 215, one end can be rotated to the top of the fixed block 203 to block the fixed block 203. Then, the upper limit block 217 of the limit rod 216 can be aligned with the upper limit groove 218 of the fixed block 203. After that, the fixed block 203 is released and the limit rod 216 moves up under the action of the telescopic spring 204 to engage the limit block 217 with the limit groove 218, thereby limiting the fixed block 203 and preventing the fixed block 203 and the J-shaped rod 206 from resetting. When the hand wheel 105 is rotated a large number of times, it is possible to avoid uniformly pressing the fixed block 203, so that the fixed block 203 can be limited after moving, thereby improving convenience.
