Description

Technical Field

[0001] This utility model relates to the field of valve equipment technology, and in particular to a sealed valve with a self-tightening sealing structure. Background Technology

[0002] Self-tightening sealing valves utilize the pressure of the fluid medium to achieve sealing. When fluid passes through the valve, the pressure of the medium automatically acts on the sealing components, causing the sealing surfaces to fit tightly together, thus achieving a seal. This sealing method differs from traditional static seals, such as rubber sealing rings or metal sealing surfaces. Traditional seals are prone to deformation or damage due to pressure fluctuations under high pressure, while self-tightening seals can automatically enhance the sealing effect as the pressure increases, ensuring the reliability and stability of the seal.

[0003] Traditional sealed valve bodies are mostly installed directly without appropriate protective devices. In complex industrial environments, the outer surface of the valve body is easily affected by external impacts, corrosion, or other environmental factors. For example, in the petroleum and chemical industries, valves are often exposed to high temperature, high pressure, and corrosive media. These harsh conditions not only accelerate the corrosion of the valve body surface but may also damage critical components such as internal seals and valve cores. Once internal components are damaged, the valve's sealing performance will drop significantly, and even leakage may occur. This will not only reduce production efficiency but may also lead to safety accidents, causing serious economic losses and environmental pollution. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sealing valve with a self-tightening sealing structure.

[0005] This utility model is achieved using the following technical solution: a sealed valve with a self-tightening sealing structure, comprising a sealed valve body, a protective shell one provided on one side of the surface of the sealed valve body, a protective shell two provided on the other side of the surface of the sealed valve body, an extension plate fixedly connected to the surface of the protective shell one, an installation rod fixedly connected to the surface of the extension plate, a limiting groove provided on the surface of the installation rod, a locking sleeve fixedly connected to the surface of the protective shell two, a through groove provided on the surface of the locking sleeve, a contraction frame fixedly connected to the surface of the locking sleeve, a telescopic spring fixedly connected to the inner wall of the contraction frame, a movable block fixedly connected to the surface of the telescopic spring, a limit rod fixedly connected to the surface of the movable block, and a protrusion fixedly connected to the surface of the movable block.

[0006] The above technical solution results in a sealed valve body, model J41H-25, which is simple and convenient to operate, has a compact structure, reliable sealing, and achieves self-tightening through medium pressure. It is suitable for high-pressure working conditions. Furthermore, the above technical solution allows for the rapid installation of protective shell one and protective shell two, facilitating personnel to protect the surface of the sealed valve body. This effectively prevents the sealed valve body from being impacted by external forces, thereby preventing damage to the internal components of the sealed valve body and improving the service life and reliability of the sealed valve.

[0007] As a further improvement to the above solution, the protrusion is fixedly connected to the upper surface of the movable block, and the limiting rod is fixedly connected to the lower surface of the movable block.

[0008] As a further improvement to the above solution, the mounting rod passes through the through slot, and the mounting rod and the through slot are adapted to each other.

[0009] As a further improvement to the above solution, the limiting rod passes through the limiting groove, and the limiting rod and the limiting groove are compatible.

[0010] The above technical solution enables the limit rod to accurately lock the position of the mounting rod, improving the stability and reliability of the installation, preventing the first and second protective shells from loosening or falling off during use, and ensuring the overall performance of the sealing valve.

[0011] As a further improvement to the above solution, the first protective shell and the second protective shell are connected, and the sealed valve body is disposed inside the first protective shell and the second protective shell.

[0012] The above technical solution can effectively protect the outer surface of the sealed valve body, prevent it from being affected by external impact or other external factors, avoid damage to the internal components of the sealed valve body, and improve the service life and reliability of the sealed valve.

[0013] As a further improvement to the above solution, the surface of the first protective shell is fixedly connected with several pre-positioning grooves, and the surface of the second protective shell is provided with several embedded rods.

[0014] Through the above technical solution, the connection strength and stability between the first protective shell and the second protective shell are further enhanced by the cooperation of the pre-positioning groove and the embedded rod, making the entire protective structure more robust and reliable, better able to withstand external impacts, and improving the overall performance and service life of the sealing valve.

[0015] As a further improvement to the above solution, the prepositioning slot is inserted into the interior of the embedded rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model's sealed valve body achieves self-tightening sealing through medium pressure, adapting to high-pressure conditions and ensuring reliable sealing performance. The self-tightening sealing method avoids the leakage problems of traditional seals under high pressure, enhancing sealing stability and reliability, and improving equipment safety. Secondly, the quick-installation design of the protective shells one and two allows for easy operation by pulling the protrusion to move the movable block, causing the limit rod to rise or fall, locking or separating it from the installation rod. This not only simplifies operation but also improves installation efficiency, avoiding the inconvenience of complex installation processes. Simultaneously, the rapid assembly of the protective shells effectively protects the outer surface of the sealed valve body, preventing damage to internal components from external impacts and significantly extending the valve's service life.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figure 1-4This embodiment of a self-tightening sealing valve includes a valve body 1, a protective shell 2 on one side of the valve body 1, and a protective shell 3 on the other side of the valve body 1. An extension plate 4 is fixedly connected to the surface of the protective shell 2, and an installation rod 5 is fixedly connected to the surface of the extension plate 4. A limiting groove 6 is formed on the surface of the installation rod 5. A locking sleeve 7 is fixedly connected to the surface of the protective shell 3, and a through groove 8 is formed on the surface of the locking sleeve 7. A contraction frame 9 is fixedly connected to the surface of the contraction frame 9, and a telescopic spring 10 is fixedly connected to the inner wall of the contraction frame 9. A movable block 11 is fixedly connected to the surface of the telescopic spring 10, and a limit rod 12 is fixedly connected to the surface of the movable block 11. A protrusion 13 is fixedly connected to the surface of the movable block 11. The valve body 1 is controlled by medium pressure. To achieve self-tightening and suitability for high-pressure applications, when assembling protective shell 12 and protective shell 23, the operator first retracts the movable block 11 by using the protrusion 13. During the retraction of the movable block 11, the telescopic spring 10 on the inner wall of the contraction frame 9 is squeezed, and the limiting rod 12 is driven to rise and enter the interior of the contraction frame 9. Subsequently, the operator inserts the mounting rod 5 on the surface of protective shell 12 into the through groove 8 on the surface of the locking sleeve 7. After the mounting rod 5 is installed in place, protective shell 12 and protective shell 23 fit together, protecting the outer surface of the sealed valve body 1. Then, the operator releases the tension on the protrusion 13. Under the reset action of the telescopic spring 10, the limiting rod 12 descends again, passing through the limiting groove 6 on the surface of the mounting rod 5, thereby locking the position of the mounting rod 5 and completing the rapid installation of protective shell 12 and protective shell 23.

[0027] The protrusion 13 is fixedly connected to the upper surface of the movable block 11, and the limiting rod 12 is fixedly connected to the lower surface of the movable block 11. During operation, the movement of the movable block 11 can be easily controlled by pulling the protrusion 13, thereby driving the limiting rod 12 to rise or fall, so as to realize the engagement or separation of the limiting rod 12 with the limiting groove 6 on the surface of the mounting rod 5.

[0028] Mounting rod 5 passes through slot 8, and mounting rod 5 and slot 8 are compatible.

[0029] The limiting rod 12 passes through the limiting groove 6. The limiting rod 12 and the limiting groove 6 are compatible. When the limiting rod 12 moves downward, it can accurately pass through the limiting groove 6 on the surface of the mounting rod 5, thereby locking the position of the mounting rod 5 and completing the quick installation between the protective shell 1 2 and the protective shell 2 3.

[0030] The protective shell 1 2 and the protective shell 2 3 are connected. The sealed valve body 1 is located inside the protective shell 1 2 and the protective shell 2 3. Through the cooperation of the protective shell 1 2 and the protective shell 2 3, an integral structure is formed, which encloses the sealed valve body 1 inside, thereby protecting the outer surface of the sealed valve body 1.

[0031] The surface of the protective shell 12 is fixedly connected with several pre-positioning grooves 14, and the surface of the protective shell 23 is provided with several embedded rods 15. During installation, when the mounting rod 5 is inserted through the inside of the groove 8, the embedded rod 15 is also inserted into the inside of the pre-positioning groove 14 at the same time, which further enhances the stability of the connection between the protective shell 12 and the protective shell 23 and the structural strength after installation.

[0032] The prepositioning slot 14 is inserted into the interior of the embedded rod 15.

[0033] The implementation principle of a self-tightening sealing valve in this embodiment is as follows: The sealing valve body 1 achieves self-tightening through the medium pressure, which can adapt to high-pressure conditions and ensure the reliability of the sealing performance. During assembly, the movable block 11 is moved into the contraction frame 9 by pulling the protrusion 13, which in turn compresses the telescopic spring 10 and drives the limiting rod 12 to rise into the contraction frame 9. Then, the mounting rod 5 on the surface of the protective shell 1 2 is inserted into the through groove 8 of the locking sleeve 7 on the surface of the protective shell 2 3. When the mounting rod 5 is inserted into place, the protective shell 1 2 and the protective shell 2 3 fit together to form an integral structure, which wraps the sealing valve body 1 inside, thereby protecting the outer surface of the sealing valve body 1. At this time, the protrusion is released. The tension of spring 10, under the elastic reset action, pushes the movable block 11 outward, thereby causing the limiting rod 12 to descend and pass through the limiting groove 6 on the surface of the mounting rod 5, thus locking the position of the mounting rod 5 and completing the rapid installation of protective shell 1 2 and protective shell 2 3. In addition, during the installation process, while the mounting rod 5 is inserted through the groove 8, the embedded rod 15 is also simultaneously inserted into the pre-positioning groove 14, further strengthening the stability of the connection between protective shell 1 2 and protective shell 2 3 and the structural strength after installation. The insertion and cooperation between the pre-positioning groove 14 and the embedded rod 15 not only improves the installation accuracy, but also enhances the robustness of the entire protective structure, enabling it to better withstand external impacts and ensuring the stability and reliability of the shut-off valve during use.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
