Description

Technical Field

[0001] The utility model relates to the technical field of pressure relief valves, in particular to a corrosion-resistant stainless steel pressure relief valve. Background Art

[0002] In modern industrial applications, pressure relief valves are key safety devices used to automatically release pressure when system pressure exceeds a predetermined safety threshold to protect the system from damage. However, traditional pressure relief valves often have some design flaws, especially when handling corrosive media. Due to the chemical properties of these media, they can cause severe corrosion to the valve body and seals.

[0003] Existing pressure relief valves are usually made of metal or non-metal materials, but these materials often cannot provide sufficient corrosion resistance when facing strong acids, strong alkalis or other corrosive chemicals. This reduces the sealing performance of the valve, shortens its service life, and increases maintenance costs. In addition, when it is necessary to maintain or replace the vulnerable parts inside the valve body, the existing disassembly and assembly methods are relatively cumbersome, which is not only time-consuming and labor-intensive, but may also cause further damage to the valve body during the disassembly process.

[0004] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a corrosion-resistant stainless steel pressure relief valve. Utility Model Content

The following description of the embodiments is only to provide a better understanding of the present utility model by showing examples of the present utility model.

[0020] Such as Figure 1, Figure 2 and Figure 3 As shown, the utility model provides a technical solution for a corrosion-resistant stainless steel pressure relief valve: comprising a valve body 1, with valve interfaces 11 provided at both ends of the valve body for connecting the system pipeline. A valve channel 12 is provided inside the valve body for the flow of the medium. A sealing notch 13 is provided on the inner wall of the valve channel for installing a sealing mechanism.

[0021] An upper interface 14 is provided above the sealing notch 13, and a top seat 2 is installed on the upper interface 14. A movable opening 21 is provided in the top seat 2, and a sealing mechanism is installed in the movable opening 21. The sealing mechanism includes a rotating sleeve 22, and a spring 23 is provided at the bottom of the rotating sleeve 22. Spring clamps 24 are installed at both ends of the spring 23, and the spring clamps 24 are connected to the rotating sleeve 22. A screw 25 is inserted into the spring 23, and a pressure head 26 is rotatably connected to the tail end of the screw 25. The pressure head 26 is wrapped with a corrosion-resistant sealing sleeve 27.

[0022] The spring seat 24 has a through hole in the middle, and the screw 25 passes through the through hole and is slidably connected thereto. The inner wall of the rotating sleeve 22 is provided with a thread groove, and the screw 25 is threadedly connected to the rotating sleeve 22, so that the screw 25 can move along the axial direction of the rotating sleeve 22, thereby adjusting the pressure of the pressure head 26 on the sealing sleeve 27.

[0023] The corrosion-resistant sealing sleeve 27 is offset against the sealing notch 13, ensuring that the sealing performance of the valve body 1 is significantly improved when facing strong acids, strong alkalis or other corrosive chemicals. The corrosion-resistant sealing sleeve 27 is made of corrosion-resistant materials, such as polytetrafluoroethylene (PTFE), Hastelloy or other corrosion-resistant materials, which can resist the erosion of various corrosive media and ensure the stability and reliability of the pressure relief valve under harsh working conditions.

[0024] Among them, the outer diameter of the corrosion-resistant sealing sleeve 27 is closely matched with the sealing notch 13 of the inner wall of the valve channel 12, thereby effectively preventing leakage of the medium. In addition, due to the use of the corrosion-resistant sealing sleeve 27, the service life of the valve is extended and the maintenance cost is correspondingly reduced. At the same time, the disassembly and assembly method of the utility model is simpler, which reduces the time and labor intensity required for maintenance or replacement of vulnerable parts, and reduces the risk of damage to the valve body 1 during the disassembly process.

[0025] In summary, the corrosion-resistant stainless steel pressure relief valve of the utility model significantly improves the corrosion resistance and sealing performance of the valve body 1 by adopting the corrosion-resistant sealing sleeve 27 and the optimized sealing mechanism design, prolongs the service life, reduces the maintenance cost, and simplifies the maintenance process.
