Description

Technical Field

[0001] This utility model belongs to the field of downhole operation tools technology, and specifically relates to a slurry displacement joint. Background Technology

[0002] In coal mining and drilling operations, slurry displacement joints are commonly used connectors to connect different types of pipes or equipment. Protecting coal seams from damage by cementing slurry and efficiently displacing mud are crucial.

[0003] Traditional slurry replacement joints are typically made of metal and have a threaded connection structure for easy installation and disassembly. While these meet basic usage needs, the sealing performance at the connection between the joint and the pipe body is usually improved by an adhesive sealing ring. However, after prolonged use, the sealing ring is easily worn down, affecting its sealing performance. Therefore, users need to replace the sealing ring periodically. Since the sealing ring is adhesively attached to the joint, replacing it is very troublesome, time-consuming, and laborious, causing significant inconvenience and failing to fully meet user needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a slurry replacement joint, which not only meets the basic requirements for connecting pipes, but also allows users to quickly and conveniently replace worn seals, thereby more fully meeting people's usage needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a slurry replacement joint, including a joint body, a first mounting cylinder detachably provided on the upper outer side wall of the joint body, an extension cylinder extending into the upper interior of the joint body on the first mounting cylinder, a clearance groove adapted to the extension cylinder on the upper inner side wall of the joint body, a first sealing ring on the inner side wall of the extension cylinder, and a second mounting cylinder detachably provided on the lower outer side wall of the joint body, with a second sealing ring on the outer side wall of the second mounting cylinder.

[0006] As a further improvement of this utility model, the first mounting cylinder is screwed to the upper outer wall of the connector body. The inner wall of the first mounting cylinder has a first internal mounting thread, and the upper outer wall of the connector body has a first external mounting thread that engages with the first internal mounting thread. The second mounting cylinder is screwed to the lower outer wall of the connector body. The inner wall of the second mounting cylinder has a second internal mounting thread, and the lower outer wall of the connector body has a second external mounting thread that engages with the second internal mounting thread. The first mounting cylinder and the upper outer wall of the connector body are connected by threads, and the inner wall of the first mounting cylinder and the upper outer wall of the connector body both have first internal and external mounting threads. Similarly, the second mounting cylinder and the lower outer wall of the connector body are also connected by threads. This structure makes installation more convenient and faster while ensuring the stability of the connection.

[0007] As a further improvement of this utility model, a sealing gasket is also provided on the inner wall of the extension cylinder, which is pressed against the top of the connector body. The sealing gasket can further improve the sealing performance of the connection between the extension cylinder, the first mounting cylinder and the upper end of the connector body.

[0008] As a further improvement of this utility model, a first rotating nut is also provided on the first mounting cylinder. The first rotating nut allows for convenient adjustment of the first mounting cylinder by turning it, thereby facilitating the connection between the first mounting cylinder and the upper end of the connector body, and enabling the user to easily install and replace the first sealing ring and the pressure contact washer.

[0009] As a further improvement of this utility model, a second rotating nut is also provided on the second mounting cylinder. The second rotating nut allows for convenient adjustment of the second mounting cylinder by turning it, thereby facilitating the connection between the second mounting cylinder and the upper end of the connector body, and enabling the user to easily install and replace the second sealing ring.

[0010] As a further improvement of this utility model, multiple reinforcing ribs are also provided at the middle side end of the connector body, and these reinforcing ribs are evenly distributed on the outer side wall of the connector body. Providing multiple evenly distributed reinforcing ribs at the middle side end of the connector body improves the overall structural strength of the connector body, enabling it to maintain good stability under high-pressure conditions.

[0011] As a further improvement of this utility model, a protective coating is also sprayed onto the outer wall of the connector body. This protective coating effectively prevents corrosive substances in the external environment from eroding the connector body, improving its corrosion resistance and extending its service life.

[0012] As a further improvement of this utility model, the first sealing ring, the second sealing ring, and the sealing gasket are all made of high-temperature resistant and corrosion-resistant rubber materials. The use of corrosion-resistant materials for both the sealing rings and the sealing gasket further enhances the overall corrosion resistance of the joint, making it suitable for various complex working conditions.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, the detachable design of the first and second mounting cylinders allows users to quickly disassemble the mounting cylinders and replace worn sealing rings (first and second sealing rings) without replacing the entire connector body, thus saving maintenance costs, improving work efficiency, and more fully meeting the actual needs of users.

[0014] Secondly, the extension cylinder is inserted into the clearance groove on the inner side wall of the upper end of the connector body, which ensures the stability and centering of the sealing structure and avoids the decrease in sealing performance due to misalignment. A first sealing ring is set on the inner side wall of the extension cylinder, and a sealing gasket is added to press against the top of the connector body, forming a double sealing structure, which significantly improves the sealing performance of the connector and prevents slurry leakage.

[0015] Thirdly, the first sealing ring, the second sealing ring, and the sealing gasket are all made of high-temperature and corrosion-resistant rubber materials, which are not only wear-resistant but also adaptable to complex working conditions, thus extending the service life of the seals. Fourth, the first and second mounting cylinders are respectively equipped with a first screw-in nut and a second screw-in nut, which makes it convenient for users to install or disassemble using tools, thus improving operating efficiency.

Detailed Implementation

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1 , 2 As shown, a slurry replacement connector includes a connector body 101. A first mounting cylinder 102 is detachably disposed on the upper outer side wall of the connector body 101. An extension cylinder 103 extending into the upper interior of the connector body 101 is also disposed on the first mounting cylinder 102. A clearance groove 104 adapted to the extension cylinder 103 is disposed on the upper inner side wall of the connector body 101. A first sealing ring 105 is disposed on the inner side wall of the extension cylinder 103. A second mounting cylinder 106 is detachably disposed on the lower outer side wall of the connector body 101. A second sealing ring 107 is disposed on the outer side wall of the second mounting cylinder 106.

[0021] like Figure 1 As shown, the first mounting cylinder 102 is screwed to the upper outer wall of the connector body 101. The inner wall of the first mounting cylinder 102 has a first internal mounting thread 201, and the upper outer wall of the connector body 101 has a first external mounting thread 202 that engages with the first internal mounting thread 201. The second mounting cylinder 106 is screwed to the lower outer wall of the connector body 101. The inner wall of the second mounting cylinder 106 has a second internal mounting thread 204, and the lower outer wall of the connector body 101 has a second external mounting thread 205 that engages with the second internal mounting thread 204. The first mounting cylinder 102 is threaded to the upper outer wall of the connector body 101. The inner wall of the first mounting cylinder 102 is provided with a first internal mounting thread 201, and the upper outer wall of the connector body 101 is provided with a first external mounting thread 202. Similarly, the second mounting cylinder 106 is also threaded to the lower outer wall of the connector body 101. This structure makes installation more convenient and quick, while ensuring the stability of the connection.

[0022] The user can install the first mounting cylinder 102 onto the upper end of the connector body 101 by screwing the first mounting external thread 202 and the first mounting internal thread 201 together, and by snapping the extension cylinder 103 onto the relief groove 104 together, and install the first sealing ring 105 onto the upper end of the connector body 101; the user can also install the second mounting cylinder 106 onto the lower side of the connector body 101 by screwing the second mounting external thread 205 and the second mounting internal thread 204 together, and install the second sealing ring 107 onto the lower end of the connector body 101.

[0023] Then, the upper end of the pipe can be connected to the upper end of the connector body 101 by screwing the pipe into the fixing internal thread 108 on the upper inner wall of the connector body 101, and the first sealing ring 105 provides a significant seal between the pipe and the upper end of the connector; the lower end of the pipe can be connected to the connector body 101 by screwing the pipe into the fixing external thread 109 on the lower outer wall of the connector body 101, and the second sealing ring 107 provides a significant seal between the pipe and the lower end of the connector.

[0024] During long-term use, the first sealing ring 105 and the second sealing ring 107 may fail due to wear. Since the first mounting sleeve 102 and the second mounting sleeve 106 are detachable, the user can directly unscrew the first mounting sleeve 102 and the second mounting sleeve 106 to replace the worn sealing rings (first sealing ring 105 and second sealing ring 107) without replacing the entire connector body 101. This significantly reduces maintenance costs and improves work efficiency.

[0025] According to another embodiment of the present invention, such as Figure 3 As shown, a sealing gasket 203 is also provided on the inner wall of the extension cylinder 103, which is pressed against the top of the connector body 101. During the process of connecting the first mounting cylinder 102 to the upper end of the connector body 101, the sealing gasket can also be pressed against the upper end of the connector body 101, thereby achieving a significant sealing connection between the extension cylinder 103 and the upper end of the connector body 101.

[0026] According to another embodiment of the present invention, such as Figure 3 , 4 As shown, a first tightening nut 301 is also provided on the first mounting cylinder 102. A second tightening nut 302 is also provided on the second mounting cylinder 106. To facilitate disassembly and installation, the first mounting cylinder 102 and the second mounting cylinder 106 are respectively provided with a first tightening nut 301 and a second tightening nut 302. Users can use a wrench or other tools to operate, which improves operating efficiency and reduces the difficulty of manual operation.

[0027] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, a plurality of reinforcing ribs 303 are also provided at the middle side end of the connector body 101, and the plurality of reinforcing ribs 303 are evenly distributed on the outer side wall of the connector body 101. The provision of a plurality of reinforcing ribs 303 at the middle side end of the connector body 101, and the even distribution of these reinforcing ribs 303 on the outer side wall of the connector body 101, improves the overall structural strength of the connector, enabling it to maintain good stability under high pressure conditions and avoid deformation or damage due to excessive pressure.

[0028] According to another embodiment of the present invention, a protective coating is also sprayed onto the outer wall of the connector body 101. The protective coating effectively prevents corrosive substances in the external environment from eroding the connector body 101, further extending the service life of the connector.

[0029] The first sealing ring 105, the second sealing ring 107, and the sealing gasket 203 are all made of high-temperature and corrosion-resistant rubber material. When the joint is put into use, the slurry flows from the top to the bottom, or from the bottom to the top, through the internal channel of the joint body 101. Because the first sealing ring 105, the second sealing ring 107, and the sealing gasket 203 are all made of high-temperature and corrosion-resistant rubber material, the joint can maintain good sealing performance and prevent slurry leakage even under high pressure or high temperature environments.

[0030] The slurry displacement joint of this application achieves advantages such as high-efficiency sealing, easy maintenance, structural stability, and corrosion resistance through innovative features such as a detachable mounting sleeve design, a double sealing structure, reinforced 303 slurry, and a protective coating. It not only extends the service life of the joint but also reduces maintenance costs, making it suitable for slurry transportation in various high-pressure, high-temperature, or corrosive environments.

[0031] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
