Are there any requirements regarding straight pipe sections before and after the installation of pressure relief valves and safety valves? Are there any other requirements?

The installation of pressure relief valves and safety valves must comply with the following requirements: 1. Straight pipe sections before and after: There should be sufficiently long straight pipe sections before and after the pressure relief valve and safety valve, respectively. This ensures that the flow rate of the medium as it passes through the pressure reducing valve and the safety valve remains stable, unaffected by pipe bends, gates, or other auxiliary equipment. 2. Installation location requirements: Pressure relief valves and safety valves should generally be installed near the point where the medium is used. If the medium needs to be transported through pipes, it is recommended to install pressure relief valves and safety valves near the outlet end of the pipes. 3. Drainage requirements: When installing pressure relief valves and safety valves, attention should be paid to the placement of drainage ports to facilitate regular inspection and maintenance. 4. Anti-freezing requirements: In cold regions, anti-freezing measures should be taken to prevent the valves of pressure relief valves and safety valves from failing to function properly due to freezing. 5. Other precautions: During the actual installation process, it is also necessary to select pressure reducers and safety valves appropriately based on factors such as medium flow rate and pressure, and to arrange and adjust them in accordance with the design schematics. At the same time, attention must also be paid to the exhaust direction of the safety valve to ensure that it can discharge the medium properly. .
