The pilot safety valve is a modern non-direct load safety valve designed for a variety of industrial applications. Its working principle is that when the medium pressure reaches the opening pressure set by the pilot valve, the pilot valve opens first, and the released medium enters the main valve through the bypass pipe, thereby achieving pressure release. This valve is widely used in many fields such as petroleum, chemical industry, electricity, metallurgy and urban gas, and is a high-quality overpressure protection device for pressurized equipment and pipelines.

1. High sensitivity: The design of the pilot safety valve enables it to be easily opened under low pressure, thereby improving the overall reaction sensitivity and ensuring that the equipment is effectively protected before the critical pressure.
2. Working stability: The main valve of the valve adopts a sleeve piston type and a double sealing valve seat structure to ensure stable opening performance under high back pressure conditions, increasing the reliability of the system.
3. Easy maintenance: The design takes maintenance convenience into consideration. Users can perform online calibration to ensure that the valve can still quickly return to its seat and close after multiple starts, greatly reducing maintenance costs.
4. Environmental protection: The innovative design of the non-flowing pilot valve helps reduce the emission of harmful media, promotes environmental protection, and meets the higher requirements of modern industry for environmental protection.
5. High durability: The internal materials and structures of the valve are optimized to ensure a long working life and stable performance of the product, and reliable operation under harsh conditions.
1. Soft seal design: The valve seat adopts a soft seal to ensure excellent sealing performance before and after the start, avoiding safety hazards caused by medium leakage.
2. Close control: Allow the working pressure to be close to the set pressure of the safety valve to ensure that the main valve opens quickly under overpressure and reaches the full start state.
3. Easy adjustment: It has the ability to adjust the opening and closing pressure difference, which can be flexibly adjusted according to actual needs to meet different application requirements.
4. Online detection: Supports online detection of the valve set pressure, which is convenient for users to conduct regular inspections and maintenance without disassembling the equipment, thereby improving the availability of the equipment.
5. Repeated start-up capability: After multiple starts, the valve can still quickly return to its seat and close without affecting its performance, ensuring continuous safety protection.
1. Petroleum and natural gas industry: Widely used in the field of oil and gas storage and transportation, providing necessary overpressure protection for various pressure vessels and pipelines.
2. Chemical production: In chemical plants, pilot safety valves ensure the safe operation of containers and reactors to avoid accidents caused by excessive pressure.
3. Power industry: In high-pressure boilers and related equipment in power stations, as a safety protection device, it cuts off the risks caused by excessive pressure.
4. Metallurgical industry: Used for pressure control in metallurgical processes to ensure that equipment damage caused by overpressure does not occur during production.
5. Urban gas supply: In gas stations and pipelines, it ensures the safe transportation of gas and prevents safety hazards caused by emergencies.
1. Installation steps:
- Confirm the working pressure and medium applicable to the valve.
- Clean the pipe interface before installation to ensure that there is no obstruction.
- Install the valve correctly on the corresponding pipe and ensure that it is tightened to a suitable degree.
- Check all connection points to ensure that there is no leakage.
2. Debugging steps:
- Turn on the system and gradually increase the pressure.
- Monitor whether the valve opens smoothly when the set pressure is reached, and check whether its flow is normal.
- Record the opening pressure and closing pressure to ensure that the valve performance meets the set requirements.
3. Maintenance steps:
- Regularly check the appearance of the valve to observe whether there is corrosion or wear.
- Perform a comprehensive functional test once a year to ensure that the safety valve works normally within the set range.
- When the valve performance is found to be degraded, it should be adjusted or repaired in time to avoid accidents.
1. What media are suitable for pilot safety valves?
- This valve is suitable for a variety of gas and liquid media, including oil, natural gas and chemical products. For specific use, please refer to the technical parameters.
2. How to confirm whether the valve is working properly?
- Perform pressure tests regularly to monitor the performance of the valve opening and closing, and observe whether there is leakage.
3. How to adjust the set pressure of the valve?
- The set pressure can be adjusted by adjusting the adjusting nut on the top of the valve. Please refer to the manufacturer's instructions for details.
4. What should I pay attention to during maintenance?
- Maintenance work must be carried out when the system pressure is zero to ensure safety and avoid accidental operation.
1. User A: We use pilot safety valves in the oil and gas industry. They have stable performance and easy maintenance. We recommend them to our peers.
2. User B: The valve is reasonably designed, very safe to use, and the hardware materials are also durable. It is a trustworthy product.
3. User C: In the use of chemical plants, the valve has performed well, has good privacy and environmental protection functions, and can work continuously.
