Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing technology, and in particular to a pipeline sealing device under high pressure. Background Technology

[0002] Pipeline sealing refers to measures taken through material or structural design to prevent fluid or solid particles from leaking from pipe joints and to prevent external impurities from entering the pipeline system. Its core function is to ensure the safety and service life of the pipeline system. Sealing prevents fluid (such as water, gas) or solid particles (such as dust, impurities) from leaking by tightly sealing pipe joints, while also preventing external factors such as small animals from damaging the pipeline. Pipelines under high pressure are more prone to leakage.

[0003] The existing high-pressure pipeline sealing devices have the following drawbacks in practical use:

[0004] In practical use, existing high-pressure pipe sealing devices are usually of a fixed length and cannot be flexibly adjusted according to the distance between the two pipes to be connected. As a result, a certain type of pipe sealing device can only be used at one distance, which limits its applicability. Utility Model Content

[0005] In view of the technical problem that existing high-pressure pipe sealing devices are usually of a fixed length and cannot be flexibly adjusted according to the distance between the two pipes to be connected, resulting in a limited range of applications for a single type of pipe sealing device, this utility model provides a high-pressure pipe sealing device.

[0006] The technical solution adopted by this utility model is: a pipeline sealing device under high pressure, including a first connector, a second connector, and an adjustment assembly.

[0024] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0025] In order to solve the problems existing in the background art, this application proposes the following technical solution: a pipeline sealing device under high pressure.

[0026] The specific technical solution includes connector 1, connector 2, and adjustment assembly 3. Adjustment assembly 3 includes a sleeve 301, a lead screw 302, a gear ring 304, a fixing hole 307, and a sealing ring 308. One end of connector 1 is inserted into the interior of connector 2. The sleeve 301 is fixedly mounted on the outer wall of connector 1, and one end of the lead screw 302 is rotatably connected to the outer wall of connector 2 via a bearing. A gear sleeve 303 is fixedly mounted on the outer wall of the lead screw 302, and the gear ring 304 is rotatably connected to the outer wall of connector 2 via a bearing. A ring 305 is fixedly installed on the outer wall of one side of 04. A fixing screw 306 is threaded into the outer wall of the ring 305. Several fixing holes 307 are opened on the outer wall of the second connector 2, and one end of the fixing screw 306 is threaded into the inside of the fixing hole 307. The sealing ring 308 is set between the outer wall of the first connector 1 and the inner wall of the second connector 2. The total length of the first connector 1 and the second connector 2 can be adjusted according to the distance between the two pipes to be sealed and connected, so that the pipe sealing device can seal and connect two external pipes with different distances.

[0027] In specific implementations, such as Figure 2 and Figure 3 As shown, the connector 1 is equipped with a filter assembly 4. The filter assembly 4 includes a filter screen 401, a support rod 402, a rotating rod 404, a striking cylinder 406, and a drain pipe 410. The filter screen 401 is fixedly installed on the inner wall of the connector 1. The filter assembly 4 is used to filter impurities in the water passing through the pipe sealing device.

[0028] Furthermore, the support rod 402 is fixedly installed on the inner wall of the connector 1, and a cylinder 403 is provided at the other end of the support rod 402 away from the inner wall of the connector 1. The rotating rod 404 is rotatably connected to the inside of the cylinder 403 through a bearing. The support rod 402 and the cylinder 403 are used to support and install the rotating rod 404.

[0029] Furthermore, a cleaning brush 411 is fixedly installed on the outer wall of the rotating rod 404, and the cleaning brush 411 is in contact with the filter screen 401. A swirl vane 405 is installed at one end of the rotating rod 404. When the rotating rod 404 rotates, it can drive the cleaning brush 411 to rotate and clean the impurities on the filter screen 401.

[0030] Furthermore, the striking cylinder 406 is fixedly mounted on the inner wall of the connector 1, and a striking rod 407 is slidably connected inside the striking cylinder 406. One end of the striking rod 407 is provided with a pressing block 409 extending to the outside of the striking cylinder 406, and a spring 408 connected to the striking rod 407 is provided on the inner wall of the striking cylinder 406. The elastic force of the spring 408 can push the striking rod 407 to rebound.

[0031] Furthermore, the drain pipe 410 is fixedly installed on the outer wall of the bottom of the connector 1, and a valve is provided on the drain pipe 410. The drain pipe 410 is used to discharge the impurities filtered out by the filter screen 401.

[0032] In specific implementations, such as Figure 1 and Figure 2 As shown, both connector 1 and connector 2 have sealing grooves 5 at their ends, and sealing gaskets 6 are provided inside the sealing grooves 5. Flanges 7 are provided on the outer walls of both connector 1 and connector 2. Flanges 7 are used to connect the sealing device to external pipes.

[0033] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0034] In use, rotating the gear ring 304 engages with the gear sleeve 303, causing the gear sleeve 303 to drive the lead screw 302 to rotate. This allows the sleeve 301 to synchronously drive the connector 1 to move axially on the lead screw 302, adjusting the distance between connector 1 and connector 2. Therefore, it achieves the function of adjusting the total length between connector 1 and connector 2 based on the distance between the two pipes to be sealed, enabling sealing connections between two pipes with different distances, thus broadening its applicability. After adjustment, threading the fixing screw 306 into the corresponding fixing hole 307 prevents the gear ring 304 from rotating. The sealing ring 308 ensures the seal between connector 1 and connector 2. The pipe sealing device connects to the external pipe through the sealing groove 5, where a sealing gasket 6 is placed, ensuring sealing even under high pressure. The sealing device ensures strong sealing when connected to an external pipeline. Water enters connector 1 through the external pipeline and then enters connector 2. The filter inside connector 1 filters impurities in the water. When water enters connector 1, it impacts the vortex vane 405, causing the vortex vane 405 to drive the rotating rod 404 to rotate. The rotating rod 404 drives the cleaning brush 411 to rotate and clean the impurities filtered out on the filter screen 401. At the same time, when the rotating rod 404 rotates, the end of the rotating rod 404 away from the vortex vane 405 will orderly squeeze the extrusion block 409, which causes the extrusion block 409 to drive the striking rod 407 to strike the filter screen 401, shaking off the impurities inside the mesh of the filter screen 401. This achieves the self-cleaning function of the filter screen 401 and prevents the filter screen 401 from being blocked by impurities. When the valve on the drain pipe 410 is opened, the impurities can be discharged.
