Pressure control characteristics and working principle of the pneumatic valve products

pneumatic pressure control valve is under a certain pressure difference, rely on changing the size of the throttle mouth fluid resistance to control the flow of throttle opening, which regulates actuators ( The hydraulic cylinder or hydraulic motor) The velocity of the pneumatic valve class. Mainly includes the throttling pneumatic valve, pneumatic valve, overflow throttle speed regulation valve and bypass collector pneumatic valve, etc. Installations for horizontal installation.
pressure control pneumatic valve product features:
pressure control pneumatic valve, pneumatic valve, also known as X flow control is a way of adopting high precision lead control flow of the multi-functional pneumatic valves. Is suitable for the need to control flow rate and pressure pipes of the pipeline, the scheduled traffic unchanged, limit excessive flow to a predetermined value, and the upstream pressure reducing appropriately, even if the main pneumatic valve upstream of the pressure change, will not affect the main pneumatic valve downstream of the flow.
: pneumatic pressure control valve selection according to pipe diameter selection, etc. Can be selected according to maximum flow and the pneumatic valve flow range.
the working principle of pneumatic pressure control valve:
display flow control pneumatic valve is its structure by automatic pneumatic valve core, manual and pneumatic valve core display parts. Display part by flow pneumatic valve movement, sensors, transmission device, electronic calculator display parts.
it is and its complex work. Measured flow by the pneumatic valve, water flow movement within the impeller, the impeller rotating and sensing transmission induction and make the electrical signal is proportional to the flow sensor, traffic signals through a wire into electronic calculators, after dealing with the calculator, the microprocessor, the flow value displayed.
manual pneumatic valve core is used to regulate traffic, according to the display value to set the desired flow rate value. Automatic pneumatic valve core is used to maintain a constant flow, namely in the pipe network pressure changes, automatic pneumatic valve core will automatically open fire under the action of the pressure down pneumatic valve mouth set to maintain the flow of value remains the same.
