Description

Technical Field

[0001] The utility model belongs to the technical field of stainless steel seamless pipes, and more specifically, particularly relates to a stainless steel seamless pipe joint. Background Art

[0002] Stainless steel seamless pipe is a pipe used to transport fluids such as water, oil, and gas. It is made of stainless steel material, has a seamless pipe wall structure, smooth inner and outer surfaces, and is not easy to scale. Therefore, it is often used in pipeline systems in chemical, petroleum, medicine, food, machinery, aerospace and other industries. When the length of a single pipeline is not enough, it is necessary to use a pipe joint to connect two stainless steel seamless pipes to extend the length of the pipeline. However, traditional pipe joints are usually formed in one piece. During installation, it is difficult to screw another stainless steel seamless pipe into it, which can easily affect the overall sealing. At the same time, it is also difficult to disassemble, and often only two stainless steel seamless pipes of the same specifications can be connected. Connecting pipes of different specifications requires replacing the entire pipe joint, which will affect the installation efficiency. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a stainless steel seamless pipe joint to solve the technical problems in the prior art that the one-piece formed pipe joint is difficult to install and disassemble and the entire pipe joint needs to be replaced to connect pipes of different specifications.

[0004] The purpose and effect of a stainless steel seamless pipe joint of the utility model are achieved by the following specific technical means:

[0011] According to a preferred embodiment, multiple groups of tightening blocks are provided on the circumferential sides of the two groups of pipe joint bodies.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The pipe joint of the device adopts a split design, which consists of two groups of pipe joint bodies.

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0022] Example:

[0023] like Figure 1 and Figure 2 As shown, the utility model provides a stainless steel seamless pipe joint, including two groups of pipe joint bodies 1, both of which are provided with seamless pipe bodies 2, and both groups of seamless pipe bodies 2 are respectively located on one side of multiple groups of limit blocks 8, and both groups of seamless pipe bodies 2 are provided with threads 12 on the surface of one end, and both groups of seamless pipe bodies 2 are respectively clamped in the two groups of pipe joint bodies 1 through the two groups of threads 12, and the staff can install it on the seamless pipe body 2 or disassemble it by rotating the pipe joint body 1, and both groups of pipe joint bodies 1 are clamped with Multiple sets of tightening blocks 3 make it easy for the staff to tighten the wrench on the pipe joint body 1. This operation method is simple and can improve work efficiency. Compared with the one-piece pipe joint, when two pipes of different specifications need to be connected, the split design only needs to replace one set of pipe joint bodies 1 with corresponding inner diameters, which can reduce the time and cost required for replacement. Multiple sets of limit blocks 8 are provided in the two sets of pipe joint bodies 1. When the staff is tightening the pipe joint, the wrench encounters obvious resistance, that is, when it hits the limit block, it can be judged that the installation is in place without the need for additional measuring tools or complicated operating steps.

[0024] like Figures 1 to 3 As shown, multiple groups of through holes 13 are provided in the two groups of pipe joint bodies 1, and the multiple groups of through holes 13 are respectively located on the circumferential sides of the two groups of mounting grooves 7. Multiple groups of fixing bolts 4 are provided on one side of the two groups of pipe joint bodies 1, and multiple groups of nuts 5 are provided on the other side of the two groups of pipe joint bodies 1. One ends of the multiple groups of fixing bolts 1 pass through the multiple groups of through holes 13 and are clamped in the multiple groups of nuts 5. The two groups of pipe joint bodies 1 are connected by the multiple groups of fixing bolts 4 and the multiple groups of nuts 5, which can provide a firm connection. At the same time, when the pipe joints need to be maintained or replaced, the bolt fixing design makes the operation easier, and the staff can more easily disassemble the connection for maintenance or replacement work, reducing maintenance time and cost.

[0025] One side of the two groups of pipe joint bodies 1 is provided with a mounting groove 7, and a second rubber ring 9 is arranged between the two groups of pipe joint bodies 1. One side of the second rubber ring 9 is clamped in one group of mounting grooves 7, and the other side of the second rubber ring 9 is clamped in the other group of mounting grooves 7. The second rubber ring 9 can improve the sealing between the two groups of pipe joint bodies 1, and can effectively fill the gap between the joints to prevent leakage of the fluid in the pipe. The pipeline system may expand and contract at different temperatures, and the second rubber ring 9 can adapt to these changes through its own elastic deformation, thereby maintaining the stability and reliability of the device.

[0026] The two groups of seamless pipe bodies 2 are both provided with a first rubber ring 6, and one side of the two groups of first rubber rings 6 is provided with multiple groups of clamping blocks 11. One side of the two groups of pipe joint bodies 1 is provided with multiple groups of clamping grooves 10, and the multiple groups of clamping blocks 11 are respectively clamped in the multiple groups of clamping grooves 10. The cooperation between the clamping blocks 11 and the clamping grooves 10 can firmly fix the first rubber ring 6 to prevent it from moving or falling off due to pressure or vibration during use, thereby ensuring the long-term stability of the sealing performance of the joint part. In addition, the design of the clamping blocks 11 and the clamping grooves 10 enables the first rubber ring 6 to be easily disassembled and reinstalled when replacement or maintenance is required, thereby reducing the difficulty of maintenance. Similarly, the two groups of first rubber rings 6 can also fill the gap between the two groups of seamless pipe bodies 2 and the two groups of pipe joint bodies 1, thereby maintaining a good sealing state, preventing fluid leakage, and improving the reliability of the entire pipeline system.

[0027] The specific usage and function of this embodiment are as follows:

[0028] The staff first puts the two groups of first rubber rings 6 on the two groups of seamless pipe bodies 2 respectively, aligns the two groups of pipe joint bodies 1 with the two groups of seamless pipe bodies 2 respectively, and then uses a wrench to clamp the multiple groups of tightening blocks 3 on the circumferential sides of the two groups of pipe joint bodies 1, and rotates the wrench. Multiple groups of limit blocks 8 are clamped in the two groups of pipe joint bodies 1. When the wrench cannot be turned, it means that it has been rotated into place. The limit blocks 8 can ensure that the pipe joints can reach a precise position during the rotation process, so that the connection is in a correct installation state. Subsequently, the staff can use multiple groups of fixing bolts 4 and multiple groups of nuts 5 to pass through the through holes on the two groups of pipe joint bodies 1. After installing the second rubber ring 9 in one of the mounting grooves 7, the fixing bolts 4 can be tightened to fix the two groups of pipe joint bodies 1 together, and then the two groups of first rubber rings 6 are respectively clamped into the two groups of pipe joint bodies 1 to complete the installation. The installation method is simple and easy, and the parts can be quickly installed and replaced, which is helpful for subsequent maintenance. Multiple groups of rubber rings can effectively ensure the sealing of the device, thereby improving the stability of the device.
