DETAILED DESCRIPTION

[0034] The embodiments of the present application will be further described below in conjunction with the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0035] As shown in Figures 1 to 2 The first aspect of the present application provides a pipe joint, which comprises a joint body 100 and a first sealing member 106; the joint body 100 comprises a first abutting portion 102 and a second abutting portion 104 connected to each other, and the first abutting portion 102 and the second abutting portion 104 are used for abutting to the edge of the outer wall of the box body; the first sealing member 106 is wrapped on the edge of the second abutting portion 104, and the first sealing member 106 abuts between the second abutting portion 104 and the box body; wherein the second abutting portion 104 abuts to the bottom of the box body.

[0036] According to the pipe joint provided by the first aspect of the present application, the setting of the first sealing member 106 effectively prevents the foaming agent from penetrating into the box body during the foaming process, thereby protecting the integrity and use performance of the box body. The first abutting portion 102 and the second abutting portion 104 of the joint body 100 are tightly attached to the edge of the outer wall of the box body, especially the second abutting portion 104 abutting to the bottom of the box body, which greatly improves the stability and reliability of the pipe joint, improves the situation that the sealing is not in place due to insufficient space at the lower part of the box body, avoids the medium such as foaming agent flowing into the box body through the gap between the second abutting portion 104 and the first sealing member 106, and avoids the scrapping of the box body. The pipe joint is designed reasonably, easy to install, can be quickly and accurately connected with the box body, and improves the production efficiency and installation quality. Therefore, the pipe joint provided by the first aspect of the present application can effectively prevent the medium from penetrating, improve the sealing performance, and enhance the stability.

[0037] Please continue to see Figures 1 to 2 The first aspect of the present application aims to provide a pipe joint which can effectively prevent the medium such as foaming agent from penetrating into the box body. The pipe joint mainly comprises a joint body 100 and a first sealing member 106.

[0038] The joint body 100 comprises a first abutting portion 102 and a second abutting portion 104, which can be formed as an integral structure by means such as integral molding. The first abutting portion 102 and the second abutting portion 104 are designed in shape and size to closely fit the edge of the outer wall of the liner, ensuring the stability and sealing of the pipe joint.

[0039] The first sealing member 106 is placed at the edge of the second abutting portion 104, and has good elasticity and sealing performance, for example, the first sealing member 106 can use rubber, silicone or other high molecular elastic materials. Taking the medium as a foaming agent for example, the main function of the first sealing member 106 is to prevent the foaming agent from penetrating into the liner during the foaming process through the tiny gap between the pipe joint and the liner, thereby protecting the integrity and function of the liner.

[0040] In particular, the second abutting portion 104 is designed to abut the bottom of the liner, which helps to further enhance the stability and sealing effect of the joint. At the same time, by arranging the second abutting portion 104 at the bottom of the liner, the situation of insufficient space at the lower part of the liner leading to poor sealing is improved, and leakage is avoided.

[0041] According to an embodiment of the present application, the first sealing member 106 is a flexible first sealing member 106.

[0042] In an embodiment of the present application, the first sealing member 106 is specially designed as a flexible first sealing member 106. This design aims to further improve the sealing performance and adaptability of the pipe joint.

[0043] The flexible first sealing member 106 is made of materials with high elasticity and wear resistance, such as closed-cell sponge, rubber, silicone, fluororubber or other high molecular elastic materials. These materials can deform when subjected to external pressure, thereby filling the tiny gap between the pipe joint and the liner. The flexible first sealing member 106 is designed to closely cover the edge of the second abutting portion 104, forming a continuous sealing layer. Its shape and size match the edge of the second abutting portion 104, ensuring that the pressure can be evenly distributed when subjected to external pressure, avoiding local pressure too large leading to sealing failure.

[0044] The flexible first sealing member 106 can be installed on the edge of the second abutting portion 104 in various ways, for example, the first sealing member 106 can be directly bonded to the edge of the second abutting portion 104. When installing, it is necessary to ensure that the sealing member and the second abutting portion 104 are closely fitted without gaps.

[0045] The flexible first seal 106 can fill the small gaps between the pipe joint and the tank shell, preventing the penetration of foaming agents, gases or liquids and other media into the tank shell. At the same time, its high elasticity and wear resistance can ensure stable sealing effect during long-term use. The flexible first seal 106 can adapt to tank shell edges of different shapes and sizes, as well as the slight deformation of the pipe joint during installation. This adaptability helps to ensure that the pipe joint maintains stable sealing performance under various working conditions. The design of the flexible first seal 106 makes the installation and maintenance of the pipe joint more convenient. During installation, no complex processing or treatment of the tank shell edge is required, and only the seal needs to be installed on the edge of the second abutting portion 104. During maintenance, there is no need to disassemble the entire pipe joint, and only the damaged seal needs to be replaced. Because the flexible first seal 106 has high elasticity and wear resistance, it can withstand greater external forces and extrusion, thereby prolonging the service life of the pipe joint. At the same time, its stable sealing performance also helps to protect the integrity and performance of the tank shell, further prolonging the service life of the entire system.

[0046] According to an embodiment of the present application, the first seal 106 is formed with a first folded edge 108 and a second folded edge 110, the first folded edge 108 is attached to the first surface 112 of the second abutting portion 104, and the second folded edge 110 is attached to the second surface 114 of the second abutting portion 104; wherein the first surface 112 and the second surface 114 are oppositely arranged.

[0047] In an embodiment of the present application, the first seal 106 is specially designed with a first folded edge 108 and a second folded edge 110. The two folded edges are respectively attached to the first surface 112 and the second surface 114 of the second abutting portion 104, wherein the first surface 112 and the second surface 114 are oppositely arranged.

[0048] The design of the first folded edge 108 and the second folded edge 110 aims to increase the contact area between the seal and the second abutting portion 104, thereby improving the reliability and stability of the seal. The first folded edge 108 is tightly attached to the first surface 112 of the second abutting portion 104, forming a continuous sealing layer. The second folded edge 110 is also tightly attached to the second surface 114 of the second abutting portion 104, and together with the first folded edge 108, it forms a complete sealing structure.

[0049] By such an arrangement, the first seal 106 can completely cover the edge of the second abutting portion 104, improving the sealing performance. The design of the first folded edge 108 and the second folded edge 110 increases the contact area between the seal and the abutting portion, thereby improving the reliability and stability of the seal. This design allows the seal to better adapt to changes in the shape and size of the abutting portion, even when subjected to external pressure or temperature changes, and can maintain stable sealing effects. The design allows the first seal 106 to adapt to abutting portions of different shapes and sizes, as well as possible minor deformations. This adaptability helps to ensure that the joint maintains stable sealing performance under various working conditions, thereby improving the reliability and safety of the entire system.

[0050] According to an embodiment of the present application, a connecting edge 116 is further formed on the first seal 106, which is connected between the first folded edge 108 and the second folded edge 110, and is attached to the edge surface 118 of the second abutting portion 104. The edge surface 118 is connected between the first surface 112 and the second surface 114.

[0051] In an embodiment of the present application, in addition to the first folded edge 108 and the second folded edge 110 mentioned earlier, a connecting edge 116 is further formed on the first seal 106. This connecting edge 116 is located between the first folded edge 108 and the second folded edge 110, and is attached to the edge surface 118 of the second abutting portion 104. The edge surface 118 is the part connecting the first surface 112 and the second surface 114, and is a transition area, whose shape and size may vary depending on the specific design of the abutting portion.

[0052] The connecting edge 116 is closely attached to the edge surface 118 of the second abutting portion 104, and together with the first folded edge 108 and the second folded edge 110 forms a complete sealing structure. This design ensures that the seal can fully cover all surfaces of the abutting portion, thereby improving the reliability and stability of the seal.

[0053] The design of the connecting edge 116 further enhances the contact area and sealing effect between the seal and the abutment. By fully covering various surfaces of the abutment, including the edge surface 118, the connecting edge 116 ensures that the seal can provide stable sealing force in all directions, thereby preventing the leakage of the blowing agent. The connecting edge 116 not only improves the sealing performance, but also enhances the structural stability of the seal. The connecting edge 116 connects the first folded edge 108 and the second folded edge 110 together, forming a more solid and stable sealing structure that can better withstand external pressure and deformation. The design of the connecting edge 116 simplifies the installation process of the seal. During installation, only the overall structure of the seal needs to be attached to the corresponding surface of the second abutment 104, without the need for complex positioning and fixing operations. During maintenance, there is no need to disassemble the entire pipe joint or sealing structure, and only the damaged first seal 106 needs to be checked and replaced, thereby reducing maintenance costs and downtime.

[0054] According to an embodiment of the present application, a pipe opening 120 is formed on the joint body 100, and the edge of the first seal 106 is arranged in a staggered manner with the pipe opening 120.

[0055] In an embodiment of the present application, the joint body 100 is usually provided with a pipe opening 120, which can be used to realize the functions of drainage, ventilation, etc., and the pipe opening 120 can also be used to connect a pipeline 122 or other fluid transmission equipment. The pipe opening 120 is located at different positions of the joint body 100, depending on the layout and functional requirements of the system. Regardless of the position of the pipe opening 120 on the joint body 100, when attaching the first seal 106, the edge of the first seal 106 needs to be arranged in a staggered manner with the pipe opening 120, i.e. the edge of the seal is not directly aligned or in contact with the pipe opening 120. This staggered design aims to avoid the first seal 106 blocking the use of the pipe opening 120, avoiding interference of the fluid passing through the pipe opening 120 by the first seal 106.

[0056] Specifically, the staggered arrangement can be achieved by adjusting the size, shape or installation position of the seal. For example, the edge portion of the seal can be designed to slightly deviate from the center line of the pipe opening 120, or the seal can be installed at a distance from the pipe opening 120.

[0057] The staggered design avoids interference between the first seal 106 and the pipe opening 120 when the first seal 106 is subjected to pressure or deformation, thereby reducing the interference of the first seal 106 with the fluid of the pipe opening 120. It ensures that the seal can be tightly attached to the surface of the abutment to form an effective sealing layer, preventing the penetration of the blowing agent.

[0058] According to an embodiment of the present application, along the length direction of the second abutment 104, the length of the first seal 106 is greater than or equal to the length of the second abutment 104.

[0059] In one embodiment of the present application, the length of the first sealing member 106 is designed to extend along the length direction of the second abutting portion 104, and its length is greater than or equal to the length of the second abutting portion 104.

[0060] This design ensures that the first sealing member 106 can fully cover the entire length range of the second abutting portion 104, thereby providing complete sealing effect. In order to meet the length matching requirement, the size and shape of the first sealing member 106 need to be customized according to the specific size and shape of the second abutting portion 104. The length of the sealing member should be long enough to ensure that it can still be closely attached to the abutting portion when subjected to pressure or deformation.

[0061] During installation, it is necessary to ensure that the first sealing member 106 is correctly placed on the surface of the second abutting portion 104, and its length direction is consistent with the length direction of the abutting portion. In addition, appropriate positioning devices or installation tools can also be used to assist the installation and positioning of the sealing member, so as to ensure its accuracy and stability.

[0062] Since the length of the first sealing member 106 is greater than or equal to the length of the second abutting portion 104, it can fully cover the entire length range of the abutting portion, thereby providing complete sealing effect. This design reduces the risk of foaming agent leakage due to insufficient length of the first sealing member, and improves the sealing performance and reliability. The length matching design makes the first sealing member 106 better adapt to second abutting portions 104 of different lengths and shapes. Even if the length or shape of the second abutting portion 104 changes, the first sealing member 106 can still maintain close attachment to the abutting portion, thereby ensuring the stability and reliability of the sealing effect. The length matching design simplifies the installation process of the first sealing member 106. Since the length of the first sealing member 106 is long enough, there is no need to worry about the installation difficulty problem caused by insufficient length. During maintenance, there is also no need to worry about the replacement difficulty problem caused by insufficient length of the first sealing member 106. Only normal maintenance procedures need to be followed for inspection and replacement.

[0063] In addition, since the first sealing member 106 can fully cover the entire length range of the second abutting portion 104 and maintain close attachment effect, it helps to improve the reliability of the entire pipe joint.

[0064] Referring to Figure 3 and Figure 4 , the second aspect of the present application provides a pipe assembly, which comprises a pipe 122, and at least one end of the pipe 122 is provided with the above-mentioned pipe joint.

[0065] According to the pipe assembly provided by the second aspect of the utility model, since the pipe joint in the above embodiment is adopted, the sealing performance of the pipe assembly can be significantly improved. Through the close fit between the first sealing element 106 and the second abutting portion 104, the leakage of the fluid medium is effectively prevented, and the safety and stability of the system are ensured. The connection structure between the pipe joint and the pipeline 122 ensures the firmness and stability of the connection. This design enables the pipe assembly to maintain a stable connection state when subjected to harsh environments such as high pressure, high temperature, or corrosive medium. The design of the pipe joint makes the installation process more convenient and fast, without the need for complex tools and steps. At the same time, during maintenance, only the damaged sealing element needs to be replaced, without the need to disassemble the entire pipe joint, thereby reducing maintenance cost and downtime. Since the pipe assembly adopts the pipe joint described above, the sealing performance, installation convenience, and the like of the entire pipe assembly are significantly improved.

[0066] Please continue to see Figure 3 and Figure 4 The pipe assembly provided by the second aspect of the utility model mainly includes a pipeline 122 and the pipe joint in the above embodiment.

[0067] The pipeline 122 is the main body of the pipe assembly and is usually made of metal, plastic, or other durable materials. The length, diameter, and wall thickness of the pipeline 122 are customized according to the specific application scenario and the characteristics of the transmission medium.

[0068] At least one end of the pipeline 122 is provided with the pipe joint described above. The pipe joint has a unique sealing structure and connection method to ensure that the fluid medium does not leak during transmission. The pipe joint includes a joint body 100 and at least one first sealing element 106, wherein the joint body 100 is formed with a pipe opening 120 for connecting with the pipeline 122. The first sealing element 106 is used to form an effective seal between the joint body 100 and the pipeline 122 or other connecting components.

[0069] The connection structure between the pipe joint and the pipeline 122 can include threaded connection, flange connection, clamp connection, and the like. The design of the connection structure should ensure the firmness and sealing of the connection, while facilitating installation and maintenance.

[0070] According to one embodiment of the utility model, the end of the pipeline 122 is provided with a first positioning portion 124, and the joint body 100 is formed with a second positioning portion 126, and the joint body 100 is adapted to be positioned and installed on the pipeline 122 through the first positioning portion 124 and the second positioning portion 126.

[0071] In one embodiment of the present application, the end of the pipe 122 is provided with a first positioning part 124, and the joint body 100 is formed with a second positioning part 126. The design of the two positioning parts enables the joint body 100 to be accurately and stably positioned and installed on the pipe 122.

[0072] The first positioning part 124 is arranged at the end of the pipe 122, and its shape, size and position are customized according to the second positioning part 126 of the joint body 100. The first positioning part 124 can adopt a protrusion, a groove, a hole or other geometric shapes to achieve precise matching with the second positioning part 126.

[0073] The second positioning part 126 is formed at the corresponding position of the joint body 100, corresponding to the first positioning part 124. The shape, size and position of the second positioning part 126 are adapted to the first positioning part 124 to ensure close matching with the first positioning part 124.

[0074] The second positioning part 126 can also adopt a protrusion, a groove, a hole or other geometric shapes to form a complement with the first positioning part 124.

[0075] During installation, first, the first positioning part 124 of the pipe 122 is aligned with the second positioning part 126 of the joint body 100. Then, the joint body 100 is fixed on the pipe 122 by appropriate connection methods (such as threaded connection, buckle connection, etc.). This positioning and installation method not only ensures the accuracy of the joint, but also improves the stability and efficiency of the installation.

[0076] Through the precise matching of the first positioning part 124 and the second positioning part 126, the accurate installation of the joint body 100 on the pipe 122 is ensured. This design reduces errors and deviations during installation, improves the assembly accuracy of the entire pipe assembly. The design of the positioning part makes the connection between the joint body 100 and the pipe 122 more stable and reliable. Even in harsh environments such as high pressure, high temperature or corrosive media, the stability and sealing of the connection can be maintained. The presence of the positioning part simplifies the installation process and reduces the skill requirements for the installer. It only needs to align and fix the first positioning part 124 with the second positioning part 126, without the need for complex measurement and adjustment work. Since the joint body 100 can be accurately and stably installed on the pipe 122, the reliability of the entire pipe assembly is improved.

[0077] According to one embodiment of the present application, the outer wall of the joint body 100 at the connection with the pipe 122 is provided with a second sealing member 128.

[0078] In an embodiment of the present application, a second sealing member 128 is provided around the outer wall at the connection between the joint body 100 and the pipe 122. This design aims to further enhance the sealing performance of the connection, ensuring that the fluid medium does not leak from the connection during transmission.

[0079] The second sealing member 128 can typically be made of elastic materials such as sealing tape, waterproof tape, rubber ring, etc. These materials have good elasticity and sealing performance, and can maintain stable sealing effect under various temperature and pressure conditions.

[0080] The shape and size of the second sealing member 128 are customized according to the specific structure and size of the connection between the joint body 100 and the pipe 122, and are typically designed as a ring or O-ring to tightly fit on the outer wall of the connection.

[0081] During installation, the second sealing member 128 is wrapped around the outer wall at the connection between the joint body 100 and the pipe 122, and can be installed by hand, mechanically or automatically. During installation, the sealing member needs to be tightly fitted on the outer wall of the connection without damage or deformation. At the same time, the sealing member needs to be appropriately compressed or stretched according to the specific installation requirements to ensure that it can generate sufficient sealing force.

[0082] The main function of the second sealing member 128 is to prevent leakage of the medium from the outer wall at the connection between the joint body 100 and the pipe 122, and can maintain stable sealing effect under various temperature and pressure conditions, thereby ensuring the safety and stability of the system. In addition, the second sealing member 128 can also play a buffering and damping role, reducing the risk of loosening or damage of the connection due to fluid impact or vibration.

[0083] The provision of the second sealing member 128 significantly improves the sealing performance of the connection between the joint body 100 and the pipe 122, which can tightly fit on the outer wall of the connection, fill the tiny gap and prevent medium leakage. Since the second sealing member 128 can maintain stable sealing effect, the stability of the entire pipe assembly system is enhanced. Even in harsh environments such as high pressure, high temperature or corrosive medium, the system can still operate normally. The use of the second sealing member 128 can also prolong the service life of the connection between the joint body 100 and the pipe 122. It can reduce the risk of loosening or damage of the connection due to fluid impact or vibration, thereby prolonging the service life of the entire pipe assembly. Since the second sealing member 128 has good elasticity and sealing performance, only the damaged sealing member needs to be replaced during maintenance, without the need to disassemble and repair the entire connection. This reduces maintenance costs and downtime.
