Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipeline technology, and in particular relates to a municipal water supply and drainage pipeline connection device. Background Technology
[0002] With the acceleration of urbanization, the construction scale of municipal water supply and drainage systems is constantly expanding, and the requirements for pipe connection devices are also becoming increasingly stringent. Traditional pipe connection methods, such as welding and flange connections, although they can achieve the basic functions of pipe connection to a certain extent, have also revealed some problems in practical applications.
[0003] When liquids are supplied to water pipes and sewage systems, water pressure is generated, and this pressure concentrates on the connectors. The connectors may loosen due to water pressure or vibration, leading to leaks. This highlights the inherent limitations of connectors, including high construction complexity, high economic costs, and difficult maintenance. Therefore, developing a stable pipe connection device is crucial. Utility Model Content
[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a municipal water supply and drainage pipeline connection device, which achieves the effect of preventing sewage leakage and improving the reliability of municipal pipeline connections.
[0005] In view of this, the present invention provides a municipal water supply and drainage pipeline connection device, including a connector, there are two connectors, the two connectors are connected by an intermediate connecting part, both connectors include a first sleeve, the first sleeve is provided with a first thread, the first thread is used for threaded connection between the connector and the drainage pipeline to be connected, the connector also includes an anti-loosening structure to prevent the threaded connection structure between the first thread of the first sleeve and the pipeline to be connected from loosening.
[0006] In this technical solution, by setting an anti-loosening structure, the connection between the connector and the municipal drainage can be prevented from loosening under natural disasters such as water pressure impact or earthquake vibration, thus preventing sewage leakage and improving the reliability of municipal pipeline connections.
[0007] Furthermore, the anti-loosening structure includes: The second sleeve is arranged around the outer periphery of the first sleeve, and the inner wall of the second sleeve is fixedly connected to the outer periphery of the first sleeve. A second thread is also provided on the inner wall of the second sleeve. The third sleeve has a third thread on its outer wall that can be threadedly connected to the second thread, and a groove is provided on the side of the third sleeve facing the first sleeve. A one-way sleeve is provided inside the settling tank and is circumferentially fixedly connected to the third sleeve through a first circumferential fixed connection structure. A one-way inner sleeve is disposed inside a one-way outer sleeve, and the side of the one-way inner sleeve facing the first sleeve is circumferentially fixedly connected to the first sleeve through a second circumferential fixing structure. The first thread has the opposite direction to the third thread. The one-way outer sleeve and the one-way inner sleeve are connected by a one-way structure so that when the third sleeve is tightened onto the second sleeve, the one-way inner sleeve does not rotate synchronously with the one-way outer sleeve.
[0008] Furthermore, the first circumferential fixing structure includes a plurality of first protrusions disposed on the outer periphery of the unidirectional outer sleeve and a plurality of first grooves disposed in the recess, wherein the shapes of the first protrusions and the first grooves are matched and can be inserted into each other.
[0009] Furthermore, the second circumferential fixing structure includes a plurality of second protrusions disposed at the head of the unidirectional inner sleeve and a plurality of second grooves disposed at the tail of the first sleeve, wherein the second protrusions and the second grooves are matched in shape and can be inserted into each other.
[0010] Furthermore, the unidirectional structure includes a spring block and a spring disposed on the outer periphery of the unidirectional inner sleeve. One end of the spring block is suspended, and the other end is rotatably connected to the outer periphery of the unidirectional inner sleeve. The spring keeps the spring block in a suspended state at all times. The inner periphery of the unidirectional outer sleeve is provided with serrated grooves.
[0011] In this technical solution, during assembly, the first protrusion of the one-way sleeve is inserted into the first groove in the groove of the third sleeve, so that the one-way sleeve is placed in the groove of the third sleeve and circumferentially fixedly connected to the third sleeve. Then, the one-way inner sleeve is placed into the inner ring of the one-way sleeve to activate the one-way structure. Next, the second protrusion of the one-way inner sleeve is inserted into the second groove at the tail of the first sleeve to circumferentially fix the one-way inner sleeve to the first sleeve. Finally, the third sleeve is rotated counterclockwise to connect and tighten with the second sleeve. During the tightening process, the one-way sleeve rotates with the third sleeve, while the one-way inner sleeve does not rotate. When it is necessary to connect this device to a municipal drainage pipe, simply tighten the assembled connector to the municipal drainage pipe thread through the first thread. In this case, the tightening direction of the connector is clockwise. The specific anti-loosening process is as follows: when external forces or vibrations cause the threaded connection between the first sleeve and the municipal drainage pipe to loosen, that is, when the first sleeve has a tendency to rotate counterclockwise, the one-way outer sleeve will have a force to prevent the one-way inner sleeve from rotating counterclockwise. Therefore, it will prevent the first sleeve from rotating counterclockwise, and the threaded connection structure between the first sleeve and the municipal drainage pipe will not be loosened by external forces, thus achieving anti-loosening in sequence.
[0012] Furthermore, a first sealing ring is provided at the bottom of the third casing trough.
[0013] Furthermore, a second sealing ring is provided at the outer peripheral end of the first sleeve.
[0014] Furthermore, a third sealing ring is provided on the inner circumferential wall of the first sleeve.
[0015] Furthermore, the second sleeve is welded to the first sleeve.
[0016] The beneficial effects of this utility model are: 1. By setting up an anti-loosening structure, the connection between the connector and the municipal drainage system can be prevented from loosening under natural disasters such as water pressure impact or earthquake vibration, thus preventing sewage leakage and improving the reliability of municipal pipeline connections.
[0017] 2. Multiple sealing rings can be used to ensure the seal of the connection and prevent municipal sewage leakage. Attached Figure Description

[0025] Example 1 like Figure 1-7 As shown, a municipal water supply and drainage pipe 23-way connection device includes a connector 1. There are two connectors 1, which are connected by an intermediate connecting part 2. Each connector 1 includes a first sleeve 3. The first sleeve 3 is provided with a first thread 4. The first thread 4 is used for threaded connection between the connector 1 and the drainage pipe 23 to be connected. The connector 1 also includes an anti-loosening structure to prevent the threaded connection structure between the first thread 4 of the first sleeve 3 and the pipe to be connected from loosening.
[0026] By setting an anti-loosening structure, the connection between connector 1 and the municipal drainage system can be prevented from loosening under natural disasters such as water pressure impact or earthquake vibration, thus preventing sewage leakage and improving the reliability of municipal pipeline connections.
[0027] The anti-loosening structure includes: The second sleeve 5 is arranged around the outer periphery of the first sleeve 3. The inner wall of the second sleeve 5 is fixedly connected to the outer periphery of the first sleeve 3. A second thread 6 is also provided on the inner wall of the second sleeve 5. The third sleeve 7 has a third thread 9 on its outer wall that can be threadedly connected to the second thread 6. The third sleeve 7 has a groove 8 on the side facing the first sleeve 3. One-way sleeve 10, the one-way sleeve 10 is disposed in the sink 8 and is circumferentially fixedly connected to the third sleeve 7 through the first circumferential fixed connection structure; One-way inner sleeve 11 is disposed inside one-way outer sleeve 10, and the side of one-way inner sleeve 11 facing the first sleeve 3 is circumferentially fixedly connected to the first sleeve 3 through a second circumferential fixed connection structure. The first thread 4 has the opposite rotation direction to the third thread 9. The one-way outer sleeve 10 and the one-way inner sleeve 11 are connected by a one-way structure so that when the third sleeve 7 is tightened onto the second sleeve 5, the one-way inner sleeve 11 does not rotate synchronously with the one-way outer sleeve 10.
[0028] The first circumferential fixing structure includes a plurality of first protrusions 12 disposed on the outer periphery of the unidirectional outer sleeve 10 and a plurality of first grooves 13 disposed in the recess 8. The first protrusions 12 and the first grooves 13 are matched in shape and can be inserted into each other.
[0029] The second circumferential fixing structure includes a plurality of second protrusions 15 disposed at the head of the unidirectional inner sleeve 11 and a plurality of second grooves 16 disposed at the tail of the first sleeve 3, wherein the second protrusions 15 and the second grooves 16 are matched in shape and can be inserted into each other.
[0030] The unidirectional structure includes a spring block 17 and a spring 18 disposed on the outer periphery of the unidirectional inner sleeve 11. One end of the spring block 17 is suspended, and the other end is rotatably connected to the outer periphery of the unidirectional inner sleeve 11. The spring 18 keeps the spring block 17 in a suspended state at the suspended end. A serrated groove 19 is provided on the inner periphery of the unidirectional outer sleeve 10.
[0031] During assembly, the first protrusion 12 of the one-way outer sleeve 10 is inserted into the first groove 13 in the recess 8 of the third sleeve 7, so that the one-way outer sleeve 10 is placed in the recess 8 of the third sleeve 7 and circumferentially fixedly connected to the third sleeve 7. Then, the one-way inner sleeve 11 is placed into the inner ring of the one-way outer sleeve 10 to activate the one-way structure. Then, the second protrusion 15 of the one-way inner sleeve 11 is inserted into the second groove 16 at the tail of the first sleeve 3 to circumferentially fix the one-way inner sleeve 11 to the first sleeve 3. Finally, the third sleeve 7 is rotated counterclockwise to connect and tighten with the second sleeve 5. During the tightening process, the one-way outer sleeve 10 rotates with the third sleeve 7, while the one-way inner sleeve 11 does not rotate. When it is necessary to connect this device to the municipal drainage pipe 23, simply tighten the assembled connector 1 to the municipal drainage pipe 23 through the first thread 4. At this time, the tightening direction of the connector 1 is clockwise. The specific anti-loosening process is as follows: when external forces or vibrations cause the threaded connection between the first sleeve 3 and the municipal drainage pipe 23 to loosen, that is, when the first sleeve 3 has a tendency to rotate counterclockwise, the one-way outer sleeve 10 will have a force to prevent the one-way inner sleeve 11 from rotating counterclockwise. Therefore, it will prevent the first sleeve 3 from rotating counterclockwise, and the threaded connection structure between the first sleeve 3 and the municipal drainage pipe 23 will not be loosened by external forces, thus achieving anti-loosening in sequence.
