The basic principle of inlet steam pressure reducing valve and the using method

by:Mech     2020-08-09
A, the basic principle of steam pressure reducing Industrial Valves: 1, the pressure regulating range: it refers to the pressure reducing Industrial Valves output pressure P2 adjustable range, meet the precision within the scope of this requirement. Regulating scope mainly related to the regulating spring stiffness. 2, pressure feature: it refers to the flow fixed value for g, caused by the input pressure fluctuation characteristics of the output pressure fluctuations. The smaller the output pressure fluctuation, the characteristics of the pressure reducing valve, the better. The output pressure must be less than the input pressure - Constant value was basically not changes over the input pressure. 3, flow characteristic: it refers to the input pressure - Timing, the output pressure changes along with the change of output flow g resistance. G when the flow changes, the output pressure changes as small as possible. Generally the lower the output pressure, which fluctuates according to the change of output flow. Second, the use of the inlet steam pressure reducing valve: first, according to the requirement of using the selected type and voltage regulation accuracy of the pressure reducing Industrial Valves, then choose the size according to the maximum output flow required. 1 mpa. After general installed in the water pressure reducing valve air filter, oil mist device or setter, and pay attention to answer against its import and export; should relax the knob when not in use, in order to avoid diaphragm often compression deformation and affect its performance.
