Constant flow valve
What is the structure (principle) of the constant flow valve?
- A structure that uses the elasticity of rubber to change the orifice diameter according to the load generated by the pressure difference.
- A structure consisting of a spring and a piston or valve that expands and contracts the spring by the load generated by the pressure difference and changes the flow path.
- A structure consisting of a diaphragm or piston and a spring / valve, which changes the valve opening according to the pressure difference between the top and bottom of the diaphragm and keeps the pressure difference before and after the fixed orifice constant.
It can be roughly divided into these structures.
