Description
Technical field
The utility model is related to control valve technology field, specially a kind of Differential Pressure Controller.
Background technology
Differential Pressure Controller is to act on opening come control valve with the medium differential pressure of return pipe using system water supply pipe
Degree, the change of pipe resistance is made up using the change in pressure drop of valve element, so that can keep pressure difference in working conditions change substantially not
Become, its operation principle：In certain range of flow, the pressure difference of controlled system (confession, water return pipeline) can be efficiently controlled
Constant, i.e., when the pressure difference of system increases, pressure-sensitive diaphragm promotes valve element to move downward, and the aperture of valve reduces, return pipe import
Pressure increases, and controlled system pressure difference then reduces；Conversely, when controlled system pressure difference reduces, pressure-sensitive diaphragm promotes valve element to transport upwards
Dynamic, valve opening increase, return pipe inlet pressure reduces, and controlled system pressure difference then increases, and final result is controlled system
Pressure difference is constant (maintenance setting value).Therefore the pressure differential resetting value of valve accurately, stably must can otherwise cause the pressure of system to lose
Weighing apparatus, has a strong impact on the reliability of heating, water supply effect and system.
