Product details of pressure reducing valve group
The pressure reducing valve group is used in the blast furnace gas pipeline system as a device to adjust the medium pressure of the pipeline

The pressure reducing valve is used to control the opening of the opening and closing parts in the valve body to adjust the flow of the medium and reduce the pressure of the medium
At the same time, the opening of the opening and closing parts is adjusted with the help of the pressure behind the valve to keep the pressure behind the valve within a certain range, and the cooling water is injected into the valve body or behind the valve to reduce the temperature of the medium
This valve is called the pressure reducing and temperature reducing valve
The characteristic of the valve is to keep the outlet pressure and temperature within a certain range when the inlet pressure changes continuously
According to the structural form, the pressure reducing valve can be divided into film type, spring film type, piston type, lever type and bellows type; According to the number of valve seats, it can be single seat type and double seat type; According to the position of the valve disc, it can be divided into positive action type and reaction type
When the output pressure of the pilot pressure reducing valve is high or the diameter is large, the pressure regulating spring is used to directly regulate the pressure, the spring stiffness must be too large
When the flow changes, the output pressure fluctuates greatly, and the structural size of the valve will also increase
In order to overcome these shortcomings, a pilot pressure reducing valve can be used
The working principle of the pilot pressure reducing valve is basically the same as that of the direct acting valve
The pressure regulating gas used by the pilot pressure reducing valve is supplied by a small direct acting pressure reducing valve
If the small direct acting pressure reducing valve is installed inside the valve body, it is called internal pilot pressure reducing valve; If the small direct acting pressure reducing valve is installed outside the main valve body, it is called external pilot pressure reducing valve
Figure 14 & mdash; 2 shows the structural diagram of the internal pilot pressure reducing valve
Compared with the direct acting pressure reducing valve, the valve adds a nozzle baffle amplification link composed of nozzle 4, baffle 3, fixed orifice 9 and air chamber B
When the distance between the nozzle and the baffle changes slightly, the pressure in chamber B will change significantly, resulting in a large displacement of the diaphragm 10 to control the up and down movement of the valve core 6, make the inlet valve port 8 open or close, and improve the sensitivity of the valve core control, that is, improve the voltage stabilizing accuracy
200X pressure reducing valve is an intelligent valve that uses the energy of the medium itself to adjust and control the pipeline pressure
For domestic water supply, fire water supply and other industrial water supply systems, the outlet pressure of the main valve can be adjusted through the pressure reducing pilot valve of the regulating valve
The outlet pressure does not change due to the change of inlet pressure and inlet flow
The outlet pressure can be safely and reliably maintained at the set value, and the set value can be adjusted as needed to achieve the purpose of decompression
The valve has the advantages of accurate pressure reduction, stable performance, safety and reliability, convenient installation and adjustment and long service life
The pressure reducing valve mainly controls the fixed outlet pressure of the main valve
The outlet pressure of the main valve will not change due to the change of inlet pressure or the change of outlet flow of the main valve
It is applicable to industrial water supply, fire water supply and domestic water pipe network system

The installation and maintenance of pressure reducing valve shall pay attention to the following matters:
For the convenience of operation and maintenance, the pressure reducing valve is generally installed vertically on the horizontal pipeline

When installing the pressure reducing valve, pay attention to make the flow direction of the medium in the pipeline consistent with the direction of the arrow on the valve
In order to prevent overpressure behind the valve, a pressure reducing valve shall be installed at least 4m away from the valve outlet
