The parallel safety return valve is an automatic pressure relief protection device specially designed for liquefied petroleum gas (LPG) stations. The valve is mainly installed on the liquid phase reflux pipeline at the outlet of the tank pump. It can automatically open when the pressure before the pump exceeds the specified value to achieve safe reflux and ensure the safe operation of the equipment and pipelines. As an important safety accessory of the pressure vessel, the parallel safety return valve can effectively prevent safety accidents caused by overpressure and ensure the stability of fluid transportation and storage.
Main material | Sealing surface material | Temperature range | Pressure range | Caliber range | Applicable standards | Connection standard | Driving mode | Applicable medium |
WCB\CF8\CF8M | PTFE\13Cr\STL | -29~425℃ | PN6~420 Clsaa150~2500 | DN25~600 NPS1~24 | GB/T12241 GB/T12221 ASME B16.10 | ASME B16.5 GB/T9113 ASME B16.25 GB/T12224 | automatic | Water, steam, oil, etc |
1. Automatic pressure relief protection: When the pressure in the container exceeds the set value, the safety return valve will automatically open by the pressure of the medium itself, quickly discharge excess liquid, and prevent the equipment from being damaged.
2. High reliability: The parallel design ensures that the valve can work stably within different flow and pressure ranges, has high reliability, and can meet the needs of complex working conditions.
3. Easy to maintain: The valve has a simple structure, is easy to disassemble and maintain, reduces the maintenance cycle and cost, and improves the overall efficiency of the system.
4. Strong safety: The working principle of the return valve ensures that it can automatically close when the pressure returns to the safe range, thereby keeping the pressure in the container always below the allowable value and automatically preventing potential accidents.
1. Parallel design: The parallel structure effectively increases the flow capacity of the valve, improves the discharge speed of the liquid, and improves the overall safety performance.
2. Static pressure opening mechanism: Relying on the inlet static pressure to open, the parallel safety return valve is more stable and reliable than valves that rely on external power.
3. High-quality valve body material: Made of corrosion-resistant and high-pressure resistant materials, it enhances the durability of the valve in harsh environments.
4. Precise pressure control: Ensure the sensitivity of the valve pivot and allow the set pressure deviation to be extremely small to enhance hysteresis awareness and stability.
5. Wide application: It can be widely used in the storage, transportation and processing of various liquid gases, especially suitable for the safe handling of high-risk media such as liquefied petroleum gas.
1. Liquefied Petroleum Gas (LPG) Station: Mainly used for the storage and transportation of liquefied petroleum gas, protecting the safety of tanks and pumps.
2. Petroleum Transportation: During the transportation of liquid petroleum, ensure the safe operation of pipelines and reduce the risk of leakage and overpressure.
3. Chemical Industry: Suitable for the storage and transportation of liquid chemicals, ensuring the integrity and safety of pressure vessel components.
4. Power Generation Industry: In the storage and use of liquid fuels, through effective pressure control, ensure the safety of the entire system.
1. Installation Steps:
- Confirm that the valve specifications correspond to the working pressure.
- Clean the pipeline interface before installation to ensure that there is no debris.
- Fix the valve at the pump outlet of the liquid phase return pipeline and tighten the bolts to ensure sealing.
- Check all connection points to ensure that there is no leakage.
2. Maintenance Steps:
- Regularly check the appearance of the valve and its key components, and pay attention to the wear of the rubber gasket and sealing ring.
- Perform a functional test at regular intervals to ensure that the safety return valve performs well.
- If the valve cannot be opened or closed normally, it should be disassembled and repaired in time.
1. What is the working principle of the parallel safety reflux valve?
- This valve automatically opens through the static pressure in the container to discharge excess media, and automatically closes after the pressure returns to normal.
2. How to determine whether the safety return valve is working properly?
- Observe the reaction of the valve under the set pressure, check whether it opens and closes flexibly, and whether there is any leakage.
3. Can the valve be used in a high temperature environment?
- Yes, the parallel safety return valve is made of high temperature resistant materials and is suitable for use in a high temperature environment. Please refer to its technical parameters for details.
4. What should I pay attention to during installation?
- During installation, ensure that the valve is consistent with the pipeline system and ensure good sealing to avoid leakage due to improper installation.
1. User A: This parallel safety return valve has stable performance and has not had any problems since it was used. It provides a good safety guarantee for our production process.
2. User B: I am very satisfied with the automatic opening and closing mechanism of the valve. It is very convenient to use and simple to maintain. It is worth recommending to peers.
3. User C: Its material and structural design are very superior, the installation and debugging process is smooth, and the use effect is excellent. It is a reliable choice in our project.
