Description

Technical Field

[0001] This utility model relates to the field of pipeline valve technology, specifically a high-temperature resistant pipeline valve. Background Technology

[0002] In fluid pipeline systems, valves are control elements whose main functions are to isolate equipment and pipeline systems, regulate flow, prevent backflow, regulate and release pressure. They can be used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, mud, oil, liquid metals and radioactive media.

[0003] When existing pipeline valves are used in high-temperature or ultra-high-temperature environments, most of them have high-temperature resistant structures such as the outer wall of the valve. However, the internal structure of the valve body is connected to the valve body for use. The internal structure of the valve body is simple. When working in ultra-high-temperature environments for a long time, the high temperature heat enters the internal structure of the valve body and damages the valve structure, causing deformation. This reduces the functionality of the valve, reduces the service life of the valve, and affects the normal operation of the pipeline valve. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a high-temperature resistant pipeline valve, which has the advantages of high temperature resistance and improved functionality of pipeline valves, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: The high-temperature resistant pipeline valve includes a gland for use with a valve body.

Support rods for connecting conductive copper plates are fixedly connected to the four sides of the outer surface of the center block. An installation rod for fixed installation is fixedly connected to one side of the support rod. Conductive copper plates are fixedly installed on the upper and lower sides of the support rod. A support rod for supporting the center block and other structures inside the valve core is fixedly connected below the center block. A ball hole for use with the pipeline valve discharge is fixedly connected below the support rod. The valve core is movably connected inside the valve body.

[0007] As a preferred embodiment of this utility model, a connecting body is fixedly connected to the lower part of the pressure cap, and mounting blocks are fixedly connected to both sides of the connecting body; the connecting body is hollow, which facilitates operation with the valve stem.

[0008] As a preferred embodiment of this utility model, mounting sleeves are fixedly connected to the outer surfaces of both ends of the valve body, and a connecting block is fixedly connected to the top of the mounting sleeve. A mounting bolt is movably connected through one side of the connecting block, and the mounting bolt is movably connected through one side of the mounting block. The connecting block and the mounting block are fixedly engaged by the mounting bolt.

[0009] As a preferred embodiment of this utility model, the valve body is fixedly connected to both ends with connecting pipes, and a sealing interface is fixedly installed on the inner wall of the connecting pipe; the sealing interface is used to connect and cooperate with the installation pipe.

[0010] As a preferred embodiment of this utility model, an inner sealing sleeve is fixedly connected to both ends of the valve body, and a sealing ring is fixedly installed on one side of the inner sealing sleeve; the sealing ring is used to increase the sealing performance between the valve core and the metal valve body.

[0011] As a preferred embodiment of this utility model, a valve core is movably connected to one side of the sealing ring, and the sealing ring is fixedly installed inside the valve body; two sealing rings are correspondingly connected to the outer surface of the valve core for cooperative use.

[0012] As a preferred embodiment of this utility model, a fixed base is fixedly installed through the lower part of the valve body, a fixed shaft is fixedly installed on the bottom of the inner surface of the fixed base, and a valve core is movably connected above the fixed shaft; the fixed shaft is used for supporting the lower part of the valve core.

[0013] Compared with the prior art, this utility model provides a high-temperature resistant pipeline valve, which has the following beneficial effects:

[0014] This invention features a central block installed at the center of the valve's interior. All four sides of the central block are fixedly connected to support rods, which in turn attach to mounting rods that connect to the inner wall of the valve core. This secures the central block and support rods within the valve body, providing internal support and effectively preventing deformation of the valve under high-temperature conditions. This enhances the overall functionality of the high-temperature resistant valve and facilitates its normal operation. Furthermore, conductive copper plates are installed on both the upper and lower sides of the support rods. These plates conduct water temperature from the pipe, helping to cool the valve body.

[0024] Specifically, the valve stem 2 is movably connected to the valve body 3 via the gland 1, and the valve stem 2 is movably connected to the valve body 3 for use. A valve core 4 is then installed inside the valve body 3. When this high-temperature resistant pipeline valve operates in a high-temperature environment, high-temperature heat enters the inner wall of the valve body 3, affecting the use of the valve core 4 and potentially causing deformation. To address this, a center block 41, a support rod 42, and an installation rod 43 are installed on the inner wall of the valve core 4. The installation rod 43 fixes the support rod 42 and the center block 41 to the inner wall of the valve core 4, facilitating internal support and preventing deformation. This ensures the normal operation of the high-temperature resistant pipeline valve and extends the service life of the valve core 4.

[0025] A connector 11 is fixedly connected to the bottom of the pressure cap 1, and mounting blocks 12 are fixedly connected to both sides of the connector 11.

[0026] Mounting sleeves 31 are fixedly connected to the outer surfaces of both ends of the valve body 3. A connecting block 32 is fixedly connected above the mounting sleeve 31. A mounting bolt 33 is movably connected through one side of the connecting block 32. The mounting bolt 33 is movably connected through one side of the mounting block 12.

[0027] Specifically, the valve body 3 is fixedly connected to the lower part of the pressure cap 1 and the connecting body 11. The connecting body 11 is connected to the mounting blocks 12 on both sides. Then, the two ends of the outer surface of the valve body 3 are connected to the mounting sleeve 31. The upper part of the mounting sleeve 31 is fixedly connected to the connecting block 32. The connecting block 32 is used to connect and cooperate with the mounting block 12. Then, the connecting block 32 and the mounting block 12 are fixedly connected by the mounting bolt 33, which facilitates the connection and stability of the valve body 3 and the connecting body 11 and makes the use of high temperature resistant pipeline valves more convenient.

[0028] Connecting pipes 34 are fixedly connected to both ends of valve body 3. Sealing interfaces 35 are fixedly installed on the inner wall of connecting pipes 34. Inner sealing sleeves 36 are fixedly connected to both ends of valve body 3. Sealing rings 37 are fixedly installed on one side of inner sealing sleeves 36.

[0029] A valve core 4 is movably connected to one side of the sealing ring 37. The sealing ring 37 is fixedly installed inside the valve body 3. A fixed base 38 is fixedly installed through the bottom of the valve body 3. A fixed shaft 39 is fixedly installed at the bottom of the inner surface of the fixed base 38. The valve core 4 is movably connected above the fixed shaft 39.

[0030] Specifically, the valve body 3 is fixedly connected to the connecting pipe 34 at both ends, and an inner sealing sleeve 36 is installed inside the valve body 3. The inner sealing sleeve 36 is used to seal the pipe connection, and the sealing ring 37 is used to seal the valve core 4 and the inner wall of the valve body 3, which facilitates the improvement of the sealing performance of the high-temperature resistant pipeline valve.

[0031] Working principle: This high-temperature resistant pipeline valve uses mounting bolts 33 to fix the mounting block 12 and connecting block 32 together. The mounting block 12 carries the upper connecting body 11, and the connecting block 32 carries the lower valve body 3. A pressure cap 1 is installed on the upper part of the connecting body 11, and the pressure cap 1 penetrates the connecting valve stem 2 structure. Subsequently, a valve core 4 is installed inside the valve body 3. The valve core 4 is installed at the lower end of the valve stem 2 for use. This allows the high-temperature resistant pipeline valve to be opened and driven by the mounting device structure. The valve stem 2 rotates with the valve core 4 for use with the mounting device structure. However, during use, the valve core 4, which operates inside the high-temperature resistant pipeline valve, is prone to deformation. A center block 41 is installed at the center of the valve core 4. The center block 41 carries a support rod 42, and the support rod 42 carries a mounting rod 43. One end of the mounting rod 43 is fixed. The center block 41 and the support rod 42 are fixedly installed on the inner wall of the valve core 4, allowing the center block 41 and the support rod 42 to be suspended inside the valve core 4 for use. This facilitates the internal support of the valve core 4 and prevents deformation of the valve core 4 in high-temperature environments. The conductive copper sheet 44 can conduct the water temperature inside the pipeline, using the input water temperature to help cool the inside of the valve body 3. The conductive copper sheet 44 conducts the water temperature to the valve core 4, and from the valve core 4, it conducts it to the inner wall of the valve body 3, which helps to reduce the excessive heat inside the valve core 4 and further increases the service life of the valve core 4. Subsequently, the support rod 45 is fixedly connected below the center block 41 and installed above the ball hole 46. The two ends of the ball hole 46 pass through the two ends of the valve core 4 on the outside. During the operation of the metal pipeline valve, the valve stem 2 carries the valve core 4 to rotate inside the valve body 3, which facilitates the normal operation of the high-temperature resistant pipeline valve.
