　　F011068 NORGREN valve group pilot valveWhat impact does it have?

　　Core tip: The pilot safety valve introduction is a non-direct load safety valve. It consists of a main valve and a pilot valve (also known as an auxiliary valve). The main valve relies on the medium discharged from the pilot valve. A simple introduction, then what impact does the F011068 NORGREN valve group pilot valve have?

　　What impact does the F011068 NORGREN valve group pilot valve have?

　　1. The valve group pilot valve is a non-direct load type safety valve. It consists of a main valve and a pilot valve (also known as "sub-valve"). The main valve relies on the medium discharged from the pilot valve, hence it is also called a "pulse safety valve". From a separate perspective, the pilot valve itself is also a direct load type safety valve. When the rotational force reaches the opening pressure of the pilot valve, the pilot valve opens first, and the discharged medium is discharged into the main bypass valve.

　　2. The first installed valve group pilot valve forms a pilot safety valve in direct safety valves. The ordinary direct test overcomes the effect of the spring to open the hydraulic effect. Spring pressure. Although the direct valve core of the pilot control valve also has a spring, the direct valve core of the pilot safety valve is different from ordinary valves. There is a small hole that allows hydraulic oil to be processed into the spring chamber. There is equivalent pressure at both the top and bottom, but the pressure in the spring chamber also acts on the valve core of the pilot valve. Returning the hydraulic oil to the tank, the pressure in the spring chamber also drops rapidly. This is the pressure difference between the pressure difference.

　　3. F011068 NORGREN valve group pilot valve: The valve group pilot valve includes two main parts, namely the pilot valve and the main valve. The valve group pilot valve can be regarded as a normal safety valve; the main valve is divided into two cavities, with the valve core's normal upper and lower cavities in between, having the same pressure. Due to the spring, the valve core of the main valve is closed. When the pressure at the safety valve inlet reaches the set pressure, the lead valve will first jump and release the pressure in the upper cavity of the main valve. It opens to achieve the effect of pressure leakage.

　　4. The valve group pilot valve is a safety protection valve. Its enabling and closing parts are in a normal closed state under external force. When the medium pressure in the equipment or pipeline increases and exceeds the specified value, it will automatically open. To prevent the pressure in the pipeline or equipment from exceeding the specified value.

　　The safety valve is an automatic valve type, mainly used for boilers, pressure vessels, and pipelines. It controls the pressure not to exceed the specified value. It plays an important protective role in personal safety and equipment operation.

　　F011068 NORGREN valve group pilot valveHow to debug the valve group pilot valve?

　　1. Cut off the switch valve upstream of the safety valve to avoid danger during the debugging process of the safety valve.

　　2. Remove the stainless steel pipeline of the main valve of the safety valve pilot valve.

　　3. Pressurize the gas source at the inlet of the safety valve pilot valve for pressure testing.

　　4. Adjust the adjustment screw of the safety valve pilot valve to press down (or loosen) the spring and observe the pressure gauge to reach the specified setting pressure of the pilot valve.

　　5. Connect the stainless steel pipe of the safety valve pilot valve and the main valve.

　　6. Reopen the switch valve upstream of the safety valve.

　　7. F011068 NORGREN valve group pilot valve: Apply fresh soapy water to the connection part of the safety valve to check the sealing of the safety valve.

　　8. Control the front pressure of the valve to make the safety valve jump, discharge, and return, repeatedly test several times, observe and record each pressure value to control the pressure within the specified accuracy.

　　9. After debugging, fix the adjustment of the nut and install the lead seal.
