Part I: General Introduction

The 500X pressure relief valve consists of a main valve, a pilot valve, a needle valve, a ball valve and a pressure gauge. It is hydraulically automatically operated and can be used as a pressure relief valve and a pressure maintaining valve. When used as a pressure relief valve, the water supply pressure can be kept below the set safety value; as a pressure maintaining valve, it can keep the upstream water supply pressure of the main valve above the set value. The 500X pressure relief valve does not require other devices and energy, is easy to maintain, and is widely used in water supply pipe network systems and urban water supply projects such as high-rise buildings and living areas.

Part IV: Parts Materials

1. Ductile iron valve body.

Ductile iron has the advantages of high strength, good toughness, wear resistance, vibration damping and so on. Production costs are relatively low, which is conducive to reducing the manufacturing cost of the valve. Good processing performance, easy to manufacture complex valve structure.

• Copper tube

①Pressure regulation: One of the main functions of the copper tube of the pressure reducing valve is to regulate the fluid pressure. When the fluid passes through the pressure reducing valve, the copper tube reduces the fluid pressure to the set value through the internal structure design to meet the needs of downstream equipment.

②Flow control: The copper tube of the pressure reducing valve can also control the fluid flow. Under high pressure, the copper tube can ensure that the fluid flows smoothly and continuously to the target equipment to avoid unstable flow caused by pressure fluctuations.

③Safety protection: The copper tube of the pressure reducing valve has excellent high temperature resistance and corrosion resistance. It can withstand various harsh environments and provide safety protection for the system. The copper tube can also prevent overload and overpressure, protecting downstream equipment from damage.

Part V: Valve Applications

1. In the field of petrochemicals, 500x pressure relief valves are widely used in various chemical plants, such as reactors, distillation towers, storage tanks, etc. They can help control the pressure in the system and prevent accidents caused by excessive pressure.

2. In addition, 500x pressure relief valves are also used in various fields of energy and electricity. For example, it can be used to control the power generation and voltage stability of the system to ensure the normal operation of the power system. At the same time, it can also help protect power equipment from damage.

3. In addition, with the continuous development of environmental water treatment, 500x pressure relief valves are also widely used in this field. They can assist in regulating the pressure and flow of sewage treatment systems, improve treatment effects and water quality. At the same time, they can also protect the environment from pollution.
