Imported steam valve basic principles and methods of use
First, the basic principle of steam valve: 1, pressure range: It refers to the pressure regulator 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 imported steam valve: First, according to the requirements of the selected type of valve and pressure regulator accuracy, and then select the maximum output flow according to its diameter. When determining the air pressure of the valve, it should be greater than the maximum output pressure 0.1MPa. Pressure reducing valve is generally installed in the water after the scrubber, mist eliminator or setter before, and be careful not to import, export reverse; valve knob should be relaxed when not in use, in order to avoid the diaphragm often affected by compression deformation Its performance.
