Description

Technical Field

[0001] This utility model relates to the field of desuperheating and pressure reducing valves, and more specifically, to a desuperheating and pressure reducing valve assembly with wide adaptability. Background Technology

[0002] The desuperheating and pressure reducing valve assembly is an industrial valve device that integrates desuperheating and pressure reducing functions. It is mainly used to simultaneously regulate the temperature and pressure of fluids to stabilize them within a specific range. It is suitable for scenarios such as power plants, chemical plants, and urban heating that require stable steam parameters and can prevent overpressure and provide protection.

[0003] Existing desuperheating and pressure-reducing valve assemblies have some problems in practical use. For example, a new type of desuperheating and pressure-reducing device with publication number CN218625599U, although it can support the equipment by installing a support plate, has a fixed height and a fixed position for the desuperheating and pressure-reducing valve. If the height of the pipes to be spliced ​​is different, it cannot be adapted for installation, affecting the adaptability of use and making it inconvenient to adjust the height of the equipment. At the same time, when assembling existing desuperheating and pressure-reducing valve assemblies, most desuperheating and pressure-reducing valves are bolted together using flanges. When assembling multiple desuperheating and pressure-reducing valves into a valve assembly, multiple bolts need to be installed with tools, which is time-consuming and labor-intensive during installation and disassembly, making it inconvenient to assemble and use the desuperheating and pressure-reducing valves conveniently.

[0004] Therefore, we have made improvements to this and proposed a desuperheating and pressure reducing valve assembly with wide adaptability. Utility Model Content

The pressure plate moves smoothly under the guidance of the slide rod. The locking block on the pressure plate can be locked in the second fixing plate for fixing and limiting. The pressure can splice and fix the inlet pipe and the outer pipe, improving the assembly pressure efficiency. Attached Figure Description

[0039] The solution in Example 1 will be further described below with reference to its specific working method.

[0040] like Figure 3 As shown, in a preferred embodiment, based on the above method, the guide plate 4 has an isosceles triangle cross section, and the bottom end of the bidirectional threaded rod 5 is higher than the top end of the guide plate 4, which can ensure that the isosceles triangle guide plate 4 can guide the movement of the support mounting frame 7 and the pulley 8.

Figure 1-7 When adjusting the height of the desuperheating and pressure reducing valve body 1, the bidirectional threaded rod 5 on the mounting base 3 can be rotated to drive the moving block 6 to move. When the moving blocks 6 on both sides move inward, they can simultaneously drive the mounting frame 7 to move. The slider 9 on the mounting frame 7 can slide and support within the mounting box 10. The pulley 8 on the mounting frame 7 can be guided by the inclined surface of the guide plate 4, driving the mounting frame 7 to move upward. The mounting frame 7 can support the desuperheating and pressure reducing valve body 1 on the mounting box 10 for height adjustment and adaptation. When the mounting box 10 drives the desuperheating and pressure reducing valve body 1 to move upward, the guide rod 2 on the desuperheating and pressure reducing valve body 1 can slide on the mounting base 3 for support and movement.

[0050] When the inlet pipe 11 or outlet pipe 12 on the de-icing and pressure reducing valve body 1 is spliced ​​with the outer pipe 14, the positioning ring 13 on the inlet pipe 11 or outlet pipe 12 can be inserted into the outer pipe 14. At the same time, the positioning ring 13 squeezes and seals the sealing gasket 15 on the outer pipe 14. When fixing, the connecting plate 18 on the first fixing plate 16 can be rotated to move the pressure plate 21 to one side of the second fixing plate 17. The rotating turntable 20 drives the transmission threaded rod 19 to rotate. The transmission threaded rod 19 can drive the pressure plate 21 to move. The pressure plate 21 moves smoothly under the guidance of the slide rod 23. The locking block 22 on the pressure plate 21 can be locked in the second fixing plate 17 for fixing and limiting.
