Voltage regulator structure characteristics and working principle of pneumatic valve

steam pressure pneumatic regulating pneumatic valve pneumatic valve is a necessary accessories, main effect is to air pressure decompression and stability to a fixed value, in order to adjust the pneumatic valve to obtain stable gas source power for regulating control.

can be divided into the form of the structure diaphragm, diaphragm spring, piston, lever and bellows type; According to the pneumatic seat number can be artificial single-seat type and two-seater type; According to the position of the pneumatic valve can be divided into different is this class action type and reaction type pneumatic valves shall generally be installed in the pipeline.

the reduced pressure pneumatic valve regulated pneumatic valve and steam pressure relief work after by pneumatic valve to control the pressure. When pressure sensor detected instruction pneumatic valve pressure, reduced pressure pneumatic valve pneumatic valve opening decreased; When they tested the vacuum pneumatic valve after pressure decreases, and reduced pressure pneumatic valve pneumatic valve opening increased.

pneumatic valve regulated mainly by regulating spring, diaphragm, pneumatic valve, pneumatic piston valve seat, disc and other parts. Using diaphragm sensor downstream pressure directly drive pneumatic valve, pneumatic control valve opening complete decompression voltage stabilizing function. This product in the urban construction, high-rise buildings in cold and hot water supply system, can replace conventional partition conduit, saving equipment. Can also be in usually hot and cold water pipe network, decompression voltage stabilizing role.

decompression regulated pneumatic valve structure

adjustable pressure regulated pneumatic valve by the main pneumatic valve and adjustable needle type pneumatic valve, pneumatic valve, pneumatic ball valve guide and take over the system composition, main pneumatic valve pneumatic valve body adopts the whole passage, once-through, streamlined design, and USES the diaphragm or piston type two kinds of structure. This product use pneumatic valve set pressure regulating guide spring pressure and adjust needle type pneumatic valve opening set outlet pressure, and by taking over the system and the control room of the feedback effect to stable outlet pressure.

adjustable pressure regulated pneumatic valve using adjustable needle type pneumatic valve, pneumatic valve with hydraulic self control, do not need additional energy and other devices, easy maintenance, affected by the inlet pressure and flow rate is small, the pressure control of high accuracy, reduced pressure regulator is reliable.

the reduced pressure regulator working principle of the pneumatic valve

when the pipeline from the inlet water supply, water flows through a needle pneumatic valve pneumatic valve in the main control room, the outlet pressure by catheter role to guide on the pneumatic valve, when the pneumatic valve outlet pressure higher than guide set data, guide the pneumatic valve is closed, the control room to stop the drainage, the main pneumatic valve control indoor pressure and close the pneumatic valve, outlet pressure is no longer rises. When the outlet pressure drop to guide the pneumatic valve set pressure guide pneumatic valve open, the control room to the downstream drainage. Due to the guide of the pneumatic valve pneumatic valve displacement is greater than the needle into the water, the main pneumatic control valve pressure drop, inlet pressure make the pneumatic valve is open. Under steady state, control water, drainage, same opening unchanged, outlet pressure constant. Adjust the guide set the outlet pressure pneumatic valve spring.
