Stainless steel relief valve basic performance and installation considerations
Selection of stainless steel relief valve in accordance with the requirements of using the selected decompression valve type and voltage regulation accuracy, then choose the size according to the maximum output flow required.
Relief valve is generally installed in the water gas filter, oil mist device or setter, and pay attention to answer against its import and export;
Valve need not when should the knob is loosened, lest often compression deformation of diaphragm and affect its performance.
The basic properties of the stainless steel relief valve provision it refers to the pressure relief valve pressure P2 output voltage adjustable range, meet the precision within the scope of this requirement.
Regulating scope mainly related to pressure regulating spring stiffness.
Stainless steel relief valve pressure characteristics of fixed value, it refers to the flow of g caused by input pressure fluctuation characteristics of the output pressure fluctuations.
The smaller the output pressure fluctuation, the characteristics of pressure relief valve, the better.
The output pressure must be less than the input pressure & ndash;
Constant value was basically not changes over the input pressure.
Stainless steel relief valve flow characteristic it refers to the input pressure & ndash;
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.
Stainless steel relief valve installation and maintenance should be paid attention to the following: 1, convenient for operation and maintenance, the valve is usually upright installation in horizontal pipe runs.
2, when installation should pay attention to the flow direction of the medium inside the pipeline and valve Hugh is shown in the same direction of the arrow.
3, in order to prevent the overpressure valve after pressure, the valve should be in the outlet of no less than 4 m to install a pressure relief valve.
