Description

Technical Field

[0001] This utility model relates to the field of mechanical seal assembly technology, specifically a mechanical seal assembly with double-sided sealing effect. Background Technology

[0002] A mechanical seal is a device used to prevent fluid (liquid or gas) leakage in rotating equipment (such as pumps, compressors, agitators, etc.). A double-sided seal refers to a mechanical seal assembly that provides a seal on both opposing surfaces, thus ensuring isolation between the internal and external environments of the equipment. The design and use of double-sided mechanical seal assemblies depend on many factors, including the application environment, pressure, temperature, and fluid properties. This type of mechanical seal is widely used in industrial equipment requiring leak prevention to ensure normal equipment operation and protect environmental safety.

[0003] Currently, most mechanical seal components used for pipeline connections on the market use only a single sealing surface for sealing. When used in high-pressure or harsh environments, the sealing performance is easily reduced due to factors such as wear, aging, and corrosion, which can lead to a decrease in sealing effect and potentially cause leakage of fluid inside the pipeline. Furthermore, if the sealing ring of a single sealing surface fails due to wear, aging, or other reasons, leakage may also occur.

[0004] Therefore, a mechanical seal assembly with double-sided sealing effect is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and the poor sealing reliability of traditional sealing components, this utility model proposes a mechanical sealing component with double-sided sealing effect.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a mechanical seal assembly with double-sided sealing effect, including an assembly block and a pipe. An inner tube is fixedly installed inside the assembly block. An annular groove is formed on the outer surface of the inner tube. A first sealing ring is fixedly installed inside the annular groove. An outer tube is movably installed on both the left and right sides of the assembly block. A slot is formed on the side of the outer tube near the assembly block. A second sealing ring is fixedly installed inside the slot.

[0007] Preferably, T-shaped rods are fixedly installed on the upper and lower sides of both the left and right sides of the assembly block, and the T-shaped rods are arranged in a vertical position.

[0008] Preferably, connecting ears are fixedly installed on both the upper and lower sides of the outer sleeve, and the connecting ears are sleeved onto the surface of the T-shaped rod.

[0009] Preferably, a spring is fitted onto the surface of the T-shaped rod, and the spring is located on the outside of the connecting lug.

[0010] Preferably, the outer sleeve has a plurality of threaded holes on its surface, which are arranged in a circumferential array.

[0011] Preferably, the internal thread of the threaded hole is connected to a clamping bolt, and the external thread of the clamping bolt is engaged with the internal thread of the threaded hole.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model achieves a double-sided sealing function through the structural design of an inner tube, annular groove, first sealing ring, outer tube, slot, and second sealing ring, and through the precise fit between the structures. This provides a double barrier, which can maintain a more stable sealing effect when facing large pressure differences or fluid pulsation, thereby avoiding the leakage problem that may occur in traditional sealing components with single-sided sealing and solving the problem of poor sealing reliability of traditional sealing components.

[0014] 2. This utility model, through the setting of the T-shaped rod, facilitates the movement of the connecting ear, thereby ensuring the stability of the outer tube during movement. It also facilitates the installation of the second sealing ring by the staff during component deployment, and can limit the spring to ensure the correct working position of the spring, thereby ensuring that the spring tension is stably released to the connecting ear. The setting of the spring facilitates the use of its deformable characteristics to provide movement space for the outer tube, and can also use its tension to compensate for the outer tube, ensuring the stability of the outer tube after installation, while reducing the working pressure of the tightening bolt.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a mechanical seal assembly with double-sided sealing effect, including an assembly block 1 and a pipe 2. An inner tube 3 is fixedly installed inside the assembly block 1. An annular groove 4 is formed on the outer surface of the inner tube 3. A first sealing ring 5 is fixedly installed inside the annular groove 4. An outer tube 6 is movably installed on both the left and right sides of the assembly block 1. A slot 7 is formed on the side of the outer tube 6 closest to the assembly block 1. A second sealing ring 8 is fixedly installed inside the slot 7.

[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 Through the cooperation of the inner tube 3, the annular groove 4, the first sealing ring 5, the outer tube 6, the slot 7, and the second sealing ring 8, a double-sided sealing function is achieved. This provides a double barrier, which can maintain the sealing effect more stably when facing large pressure differences or fluid pulsation. The double-sided sealing can enhance the stability of the mechanical sealing component. At the same time, the double-sided sealing provides a backup sealing system, which can effectively improve the durability of the entire sealing system when facing harsh working conditions, reduce maintenance and downtime caused by sealing problems, and thus avoid the leakage problems that may occur with the single-sided sealing of traditional sealing components.

[0025] T-shaped rods 9 are fixedly installed on the top and bottom sides of both the left and right sides of the assembly block 1, and the T-shaped rods 9 are arranged in a vertical position.

[0026] Reference Figure 2 and Figure 4The T-shaped rod 9 facilitates the movement of the connecting lug 10, thereby ensuring the stability of the outer sleeve 6 during movement. It also facilitates the installation of the second sealing ring 8 by the staff during component deployment. In addition, it can limit the spring 11 to ensure the correct working position of the spring 11, thereby ensuring that the tension of the spring 11 is stably released to the connecting lug 10.

[0027] Connecting ears 10 are fixedly installed on both the upper and lower sides of the outer tube 6, and the connecting ears 10 are fitted onto the surface of the T-shaped rod 9.

[0028] Reference Figure 3 and Figure 4 The connecting ear 10 facilitates the connection between the outer tube 6 and the T-shaped rod 9, thereby limiting the position of the outer tube 6 and ensuring its stability during deployment and use. At the same time, the tension of the spring 11 can be transmitted to the outer tube 6 to ensure that the end face of the outer tube 6 is stably attached to the working surface of the assembly block 1.

[0029] A spring 11 is fitted onto the surface of the T-shaped rod 9, and the spring 11 is located outside the connecting lug 10.

[0030] Reference Figure 4 The spring 11 facilitates the movement space of the outer tube 6 by utilizing its deformable characteristics, and at the same time, it can also use its tension to compensate for the outer tube 6, so as to ensure the stability of the outer tube 6 after installation. It also reduces the working pressure of the clamping bolt 13, thereby improving the stability of the component after deployment and ensuring the effect of double sealing.

[0031] The outer tube 6 has several threaded holes 12 on its surface, which are arranged in a circumferential array.

[0032] Reference Figure 3 and Figure 4 The threaded hole 12 provides space for the installation of the clamping bolt 13, so that the clamping bolt 13 can fix the outer sleeve 6 to the surface of the pipe 2. At the same time, the circumferentially distributed clamping bolt 13 can also evenly distribute the vibration generated when the pipe 2 transports fluid.

[0033] The threaded hole 12 is internally threaded with a clamping bolt 13, and the external thread of the clamping bolt 13 is engaged with the internal thread of the threaded hole 12.

[0034] Reference Figure 1 and Figure 4 The outer sleeve 6 is fixed to the surface of the pipe 2 by tightening the bolt 13 to facilitate the engagement of the threaded hole 12, thereby ensuring the stability of the overall component after deployment and thus ensuring the sealing effect of the double-sided seal.

[0035] Working principle: When using this device, hold the assembly block 1, deploy the first sealing ring 5 through the annular groove 4, and deploy the second sealing ring 8 through the slot 7. Insert one side of the pipe 2 into the surface of the inner tube 3 and the inside of the outer tube 6. The outer wall of the first sealing ring 5 contacts the inner wall of the pipe 2 to complete a single-sided seal. After the end of the pipe 2 close to the assembly block 1 contacts the assembly block 1, hold the outer tube 6 and move it towards the assembly block 1. The spring 11 releases tension simultaneously, pushing the connecting ear 10 to move towards one side of the assembly block 1. The connecting ear 10 drives the outer tube 6 to move synchronously. When the outer tube 6 fits against the assembly block 1, the inner wall of the slot 7 presses against the second sealing ring 8 to complete the second-sided seal. Install the clamping bolt 13 through the threaded hole 12. The clamping bolt 13 contacts the surface of the pipe 2 to complete the fixation of the outer tube 6. Hold the other pipe 2, insert the end face of the other side of the pipe 2 into the surface of the other inner tube 3 and the inside of the outer tube 6 and fit against the other side of the assembly block 1. Deploy the outer tube 6 again to complete the double-sided seal of the pipe 2.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
