[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Mechanical seals, also known as end face seals, are contact-type sealing devices used on rotating shafts. They are widely used in rotating equipment such as pumps, compressors, and reactors to prevent fluid media (such as liquids and gases) from leaking from the gap between rotating and stationary parts under pressure. They also prevent impurities from the external environment from entering the internal system. According to relevant national standards, a mechanical seal is defined as: a device that prevents fluid leakage by having at least a pair of end faces perpendicular to the axis of rotation remain in contact and slide relative to each other under the action of fluid pressure, the elastic force (or magnetic force) of the compensation mechanism, and auxiliary sealing.

[0021] Please see Figures 1-3 As shown, this embodiment provides a mechanical seal that is easy to position and install, including an upper pipe 100 and a lower pipe 200. The upper pipe 100 and the lower pipe 200 are connected by their pipe heads to form a mechanical pipe. Considering that the installation process of traditional mechanical seals is complicated, it may be difficult for operators to accurately perform the installation steps, which is time-consuming and increases the risk of errors. Furthermore, alignment problems may occur, making it impossible for the seal to be installed correctly. Repeated adjustments and attempts are required, wasting a lot of time and effort, affecting the sealing effect, and increasing the risk of leakage. Therefore, the following is the specific method: the upper pipe 100 is slidably engaged with the upper seal 101 on its outer wall, and the lower pipe 200 is slidably engaged with the lower seal 201 on its outer wall. The upper seal 101 has a linear array of several limiting grooves 1010 on its outer wall.

[0022] The inner wall of the lower seal 201 is symmetrically provided with grooves 2010, and a limiting and fixing component 300 is provided inside the groove 2010. The seal and the lower seal 201 are adjusted and limited and fixed by the limiting and fixing component 300 and several limiting grooves 1010.

[0023] The improvement in this embodiment is as follows:

[0024] By using the limiting groove 1010 and the limiting fixing component 300 together, the upper seal 101 and the lower seal 201 can be precisely positioned and fixed during installation. Precise positioning and fixing can ensure the stability of the seals during operation and reduce the risk of loosening or leakage caused by vibration or impact. Furthermore, by using the limiting groove 1010 and the limiting fixing component 300 together, the seals can be quickly installed and positioned through simple insertion and removal actions, and the upper seal 101 and the lower seal 201 can be quickly installed and removed. At the same time, by using the limiting groove 1010 and the limiting fixing component 300 together, it can also adapt to sealing pipe heads of different heights and sizes, improving the versatility and interchangeability of the seals.

[0025] Specifically, the limiting and fixing assembly 300 includes a support rod 301 and a limiting block 302. One end of the support rod 301 is fixedly connected to the side wall of the limiting block 302. An elastic spring 3010 is provided on the axial side of the support rod 301. One end of the elastic spring 3010 is fixedly connected to the side wall of the limiting block 302, and the other end is fixedly connected to the bottom end of the groove 2010. The limiting block 302 is adapted to and cooperates with the limiting groove 1010. The other end of the support rod 301 passes through the groove 2010 to the outside and is movably connected to the groove 2010. A gripping block 3011 is fixedly connected to the end of the support rod 301.

[0026] The support rod 301 is movably connected to the groove 2010, allowing the support rod 301 to move freely within the groove 2010 for easy adjustment and positioning. The elastic spring 3010 provides the necessary elastic force for the limiting and fixing assembly 300. During installation, the elastic spring 3010 automatically adapts to the shape of the surfaces of the upper pipe 100 and the lower pipe 200, ensuring a tight fit between the upper seal 101 and the outer walls of the upper pipe 100 and the lower pipe 200. The limiting block 302 is adapted to the limiting groove 1010 on the outer wall of the upper seal 101, allowing for quick installation and positioning of the upper seal 101 and the lower seal 201 through simple insertion and removal, greatly simplifying the installation process and improving work efficiency. The grip block 3011 is fixedly connected to the end of the support rod 301, facilitating the operator's gripping and adjustment during installation.

[0027] Considering the cumbersome steps and tool requirements of traditional sealing installation methods, symmetrical track grooves 102 are provided on the outer walls of both the upper pipe 100 and the lower pipe 200. symmetrical locking blocks 1011 are provided on the inner walls of both the upper seal 101 and the lower seal 201. The locking blocks 1011 cooperate with the track grooves 102. By symmetrically providing track grooves 102 on the outer walls of the upper pipe 100 and the lower pipe 200, a clear guiding path is provided for the installation of the upper seal 101 and the lower seal 201. The locking blocks 1011 slide freely within the track grooves 102, enabling rapid installation and positioning of the upper seal 101 and the lower seal 201, greatly improving installation efficiency.

[0028] In addition, one end of the upper seal 101 extends into the interior of the lower seal 201, and the lower seal 201 encloses the upper seal 101 inside it. The inner wall of the upper seal 101 fits against the outer wall of the mechanical pipe. Through the tight combination of the upper seal 101 and the lower seal 201, leakage of fluid at the interface between the upper pipe 100 and the lower pipe 200 can be effectively prevented, thereby improving the reliability of the system.

[0029] In practical use, the mechanical seal of this utility model, which facilitates positioning and installation, is used by the operator to first push the upper seal 101 to the appropriate position along the track groove 102 using the locking block 1011, based on the height dimensions of the pipe heads of the upper pipe 100 and the lower pipe 200. Then, the lower seal 201 is pushed to the appropriate position in the same way, enclosing the upper seal 101 inside. During the installation process, the operator holds the gripping block 3011 and, through a simple insertion and removal action, makes the limiting block 302 disengage from the limiting groove 1010 into the groove 2010. Conversely, the elastic force of the elastic spring 3010 is used to spring the limiting block 302 into the limiting groove 1010, thereby achieving rapid installation and positioning of the upper seal 101 and the lower seal 201.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
