A double-seal valve to prevent external leakage

Abstract

This utility model relates to the field of sealing valve technology, specifically to a double-sealed valve that prevents external leakage. It includes a valve body with a rotatable sealing valve inside for sealing the valve body. Filter plates for filtering impurities are movably installed at both ends of the valve body. A vibration assembly is also installed inside the valve body to prevent the filter plates from clogging. The filter plates inside the valve body can filter impurities in the water flow, preventing them from affecting the normal operation of the valve body and further protecting it. When water flows through the valve body, the impact of the water flow drives the rotating blade to rotate, which in turn drives the rotating rod and protrusion to rotate. The rotating protrusion reciprocates to compress the arc-shaped block and the compression rod. Simultaneously, the filter plate at one end of the compression rod vibrates reciprocally under the action of a spring-loaded telescopic rod, preventing impurities in the water flow from clogging the filter holes inside the filter plate and thus affecting the water flow speed.

Description

Technical Field

[0001] This utility model relates to the field of sealing valve technology, specifically to a double-sealed valve that prevents external leakage. Background Technology

[0002] Valves come in many varieties, but their basic function remains the same: to connect or disconnect the flow of media. To ensure that a valve can effectively disconnect the flow of media and prevent leakage, it is essential to ensure that the valve's seal is intact. Therefore, the sealing problem of valves is particularly important.

[0003] Chinese Patent Publication No. CN216344025U discloses a double-sealed valve for construction to prevent external leakage. The valve includes an upper shell and a lower shell. Connecting sleeves are attached to both sides of the upper shell, and a valve body is connected to the lower part of the upper shell. Sealing gaskets are provided on both sides of the valve body, and water holes are provided inside the valve body. Threaded holes are provided at both ends of the valve body, and buffer holes are provided above the water holes. This double-sealed valve for construction uses a slider to control the movement of sealing blocks on both sides. Sealing grooves on the sealing blocks press against the convex rings, thus achieving a seal. During the entire sealing process, the sealing surfaces of the sealing blocks and the sealing surfaces inside the valve body are not subjected to friction, thereby greatly extending the valve's lifespan and preventing leakage. Simultaneously, the buffer plates dissipate the impact on the sealing blocks caused by water hammer when the valve is closed, ensuring the integrity of the sealing blocks and preventing damage.

[0004] The aforementioned device uses a lead screw to drive a slider to move, thereby sealing the valve body. However, during operation, the water flow contains a large number of impurities, which can easily affect the normal operation of the lead screw, causing it to be unable to effectively drive the slider to move, and thus unable to effectively seal the valve body. Utility Model Content

[0005] To address the aforementioned issues, a double-seal valve designed to prevent external leakage is provided. By utilizing an internal filter plate, impurities in the water flow are filtered, preventing them from affecting the valve's normal operation and further protecting the valve body. When water flows through the valve body, the impact of the water flow causes the rotating blade to rotate, simultaneously rotating the rotating rod and the protrusion. The rotating protrusion reciprocates to compress the arc-shaped block and the compression rod. Simultaneously, the filter plate at one end of the compression rod vibrates reciprocally under the action of a spring-loaded telescopic rod, preventing impurities in the water flow from clogging the filter holes inside the filter plate and thus affecting the water flow rate.

[0006] To address the problems of existing technologies, this utility model provides a double-sealed valve to prevent external leakage, comprising a valve body, a sealing valve rotatably disposed inside the valve body, filter plates movably disposed inside both ends of the valve body, a vibration component for preventing filter plate clogging disposed inside the valve body, and a moving component for facilitating cleaning of the filter plates disposed inside the valve body.

[0007] Preferably, the vibration assembly includes an annular block movably disposed inside the valve body. Symmetrical spring telescopic rods are provided on the side wall of the annular block. The telescopic ends of the spring telescopic rods are connected to the side wall of the filter plate. Symmetrical connecting blocks are provided on the other side wall of the annular block. A rotating rod is rotatably disposed between the two connecting blocks. Rotating blades are provided on the outside of the rotating rod. A pressing rod is also provided on the side wall of the filter plate. One end of the pressing rod passes through the annular block and is provided with an arc-shaped block. An eccentric protrusion is provided on the outer wall of the rotating rod, which can periodically press the arc-shaped block as the rotating rod rotates.

[0008] Preferably, the moving component includes a bidirectional screw rotatably disposed inside the valve body, with threaded blocks screwed to both ends of the bidirectional screw, and a linkage block rotatably disposed on the side wall of the threaded block, one end of the linkage block being connected to the side wall of the connecting block.

[0009] Preferably, each of the two connecting blocks has a limiting block on its opposite outer side wall, and the inner wall of the valve body has a limiting groove for the limiting blocks to move.

[0010] Preferably, the outer wall of the valve body is provided with a limit cover, and the limit cover is embedded with a sealing gasket.

[0011] Preferably, the outer wall of the valve body is provided with a threaded groove for easy connection.

[0012] The advantages of this utility model compared to the prior art are:

[0013] The filter plate inside the valve body can filter impurities in the water flow, preventing them from affecting the normal operation of the valve body and further protecting it. When water flows into the valve body, the impact of the water flow will drive the rotating blade to rotate, which will also drive the rotating rod and the protrusion to rotate. The rotating protrusion can reciprocate to squeeze the arc-shaped block and the squeezing rod. At the same time, the filter plate at one end of the squeezing rod will reciprocate under the action of the spring telescopic rod, preventing impurities in the water flow from clogging the filter holes inside the filter plate and thus affecting the flow rate of the water.

[0014] By rotating the bidirectional screw, the two threaded blocks are driven to move away from each other. The linkage block on the side wall of the threaded block squeezes the connecting block, causing the connecting block to move to the outside of the valve body. This further drives the annular block and filter plate to move outward. When the filter plate moves to the outside of the valve body, it can be cleaned, thus ensuring the normal use of the valve body in the later stages. Attached Figure Description

Detailed Implementation

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 6 As shown, this utility model provides:

[0024] A double-seal valve for preventing external leakage includes a valve body 1, a sealing valve 2 rotatably disposed inside the valve body 1, filter plates 6 movably disposed inside both ends of the valve body 1, a vibration component for preventing the filter plates 6 from clogging inside the valve body 1, and a moving component for facilitating cleaning of the filter plates 6 inside the valve body 1.

[0025] When the sealing valve 2 is rotated 90° to the open position, the water flow channel is opened, and the medium can flow through the valve body 1. At the same time, the filter plate 6 inside the valve body 1 can filter impurities in the water flow, preventing impurities from affecting the normal operation of the valve body 1, avoiding wear of the inner wall of the valve body 1 by impurities, and extending the service life of the valve. Then, the vibration component prevents impurities in the water flow from clogging the filter holes inside the filter plate 6, thereby affecting the flow rate of the water. Finally, the moving component moves the filter plate 6 to the outside of the valve body 1 for cleaning, thus ensuring the normal use of the valve body 1 in the later stage.

[0026] like Figure 4 and Figure 5 As shown, the vibration assembly includes an annular block 7 movably disposed inside the valve body 1. Symmetrical spring telescopic rods 9 are provided on the side wall of the annular block 7. The telescopic ends of the spring telescopic rods 9 are connected to the side wall of the filter plate 6. Symmetrical connecting blocks 11 are provided on the other side wall of the annular block 7. A rotating rod 17 is rotatably disposed between the two connecting blocks 11. A rotating blade 8 is provided on the outside of the rotating rod 17. A pressing rod 10 is also provided on the side wall of the filter plate 6. One end of the pressing rod 10 passes through the annular block 7 and is provided with an arc-shaped block 16. An eccentric protrusion 15 is provided on the outer wall of the rotating rod 17. As the rotating rod 17 rotates, it can periodically press the arc-shaped block 16.

[0027] When water flows into valve body 1, the impact of the water flow will drive the rotating blade 8 to rotate, and at the same time drive the rotating rod 17 and the protrusion 15 to rotate. The rotating protrusion 15 can reciprocate to squeeze the arc-shaped block 16 and the squeezing rod 10. Meanwhile, the filter plate 6 at one end of the squeezing rod 10 will reciprocate under the action of the spring telescopic rod 9 to prevent impurities in the water flow from clogging the filter holes inside the filter plate 6.

[0028] like Figure 3 The moving component includes a bidirectional screw 3 rotatably disposed inside the valve body 1. Threaded blocks 14 are screwed to both ends of the bidirectional screw 3. A linkage block 13 is rotatably disposed on the side wall of the threaded block 14. One end of the linkage block 13 is connected to the side wall of the connecting block 11.

[0029] By rotating the bidirectional screw 3, the two threaded blocks 14 are driven to move away from each other. The linkage block 13 on the side wall of the threaded block 14 presses the connecting block 11, causing the connecting block 11 to move outward of the valve body 1, which in turn drives the annular block 7 and the filter plate 6 to move outward.

[0030] like Figure 2 and Figure 3 As shown, each of the two connecting blocks 11 has a limiting block 12 on its opposite outer side wall, and the inner wall of the valve body 1 has a limiting groove for the limiting block 12 to move.

[0031] The use of the limiting groove makes the limiting block 12 and the connecting block 11 more stable when moving.

[0032] like Figure 2 As shown, a limit cover 4 is provided on the outer wall of the valve body 1, and a sealing gasket 5 is embedded in the limit cover 4.

[0033] Water leakage is prevented by the sealing gasket 5 inside the limit cover 4, thus giving the valve body 1 a better sealing effect.

[0034] like Figure 1 As shown, the outer wall of valve body 1 is provided with threaded grooves for easy connection.

[0035] When valve body 1 is needed, the external water pipe is connected to the outer wall of valve body 1 by means of a connector threaded connection. The threaded groove facilitates the connection between valve body 1 and the connector.

[0036] Working principle: When valve body 1 is needed, the external water pipe is connected to the outer wall of valve body 1 via a connector threaded connection. At this time, the connector will abut against the sealing gasket 5 inside the limit cover 4, which can effectively prevent water leakage and give valve body 1 a better sealing effect. Then, the sealing valve 2 is rotated to allow water to flow through valve body 1. At the same time, the filter plate 6 inside valve body 1 can filter impurities in the water flow, preventing impurities in the water flow from affecting the normal operation of valve body 1 and further protecting valve body 1. When water flows through valve body 1, the impact of the water flow will drive the rotating blade 8 to rotate, and at the same time drive the rotating rod 17 and the protrusion 15 to rotate. The rotating protrusion 15 can reciprocate to squeeze The arc-shaped block 16 and the squeezing rod 10, along with the filter plate 6 at one end of the squeezing rod 10, reciprocate under the action of the spring telescopic rod 9, preventing impurities in the water flow from clogging the filter holes inside the filter plate 6 and thus affecting the flow rate of the water. When it is necessary to clean the filter plate 6, simply remove the connecting frame and the water pipe, then rotate the bidirectional screw 3 to drive the two threaded blocks 14 away from each other. The linkage block 13 on the side wall of the threaded block 14 squeezes the connecting block 11, causing the connecting block 11 to move towards the outside of the valve body 1, further driving the annular block 7 and the filter plate 6 to move outward. When the filter plate 6 moves to the outside of the valve body 1, it can be cleaned, thus ensuring the normal use of the valve body 1 in the later stages.
