Imported steam valve basic principles and methods of use:
First, the basic principle:
1, the pressure regulating range: It refers to the pressure regulating valve output pressure P2 adjustable range, within the scope of this requirement to achieve the required accuracy. Regulating pressure range and the main degree of pressure on the degree of spring.
2, the pressure characteristics: It refers to the flow rate g is set value, due to input pressure fluctuations caused by the pressure fluctuations in the output characteristics. The smaller the output pressure fluctuation, the better the characteristics of the pressure reducing valve. The output pressure must be lower than the input pressure - the setting will not substantially change with the input pressure.
3, the flow characteristics: It refers to the input pressure - timing, the output pressure g with the output flow changes in the holding capacity. When the flow rate g changes, the output pressure changes as small as possible. The lower the general output pressure, the smaller it fluctuates as the output flow changes.
Second, the use of methods:
1, First of all, according to the requirements of the use of selected types of pressure reducing valve and pressure regulator accuracy;
2, and then select the maximum diameter of the output flow path. When determining the air pressure of the valve, it should be greater than the maximum output pressure 0.1MPa. Valve import pump industrial washing machine
3, the pressure relief valve is generally installed in the water after the filter, mist eliminator or setter before, and be careful not to import, export reversed;
4, the valve should not be used when the knob to relax, so often deformed diaphragm and affect its performance.
