Adjustable with reduced pressure pneumatic valve working principle - water Pneumatic butterfly valve

　. Works: reduced pressure of the pneumatic valve outlet pressure by the adjusting bolt of the pneumatic valve to control, it has to do with the pneumatic valve needle coordinated operation of the pneumatic valve, pneumatic valve after a set but will remain as a constant pressure constant. The flow direction of medium pneumatic valve opens, when the main export as well as through pneumatic valve guide into the main pneumatic valve cavity on the diaphragm chamber, make the main pneumatic valve plate openings highly stable in a certain value, the pneumatic valve after pressure is constant. When the outlet pressure increases, the medium with pressure feedback system main pneumatic valve cavity pressure, inferior vena pressure balance on the principal of the pneumatic valve was damaged, pneumatic valve opening value decreases, and increase the velocity of by opening medium, pressure loss after kinetic energy change, pneumatic valve after pressure be reduced. On the other hand, when the pneumatic valve pressure is reduced, the main pneumatic valve plate opening increases, pneumatic valve after pressure. 。 Purpose: the new adjustable pressure pneumatic valve installed in the city of one-way horzontally, can high pneumatic valve upstream ( Inlet pressure to conform to the requirements of the use of downstream ( Outlet pressure, no matter how changes in upstream pressure and flow, setting good downstream pressure remains constant. 。 Structure: the composition of new type adjustable pressure pneumatic valve pneumatic valve, pressure feedback system, by the main control line. Main pneumatic valve by pneumatic valve, diaphragm, pneumatic valve cover, diaphragm, pneumatic valve stem, pneumatic valve plate and other major parts. Pressure feedback system consists of pneumatic valve assembly and control guide line. Control line by the gate of pneumatic valve, filter, pressure gauge, piping accessories. 。 Technical parameters: a, nominal pressure:. MPab, outlet pressure: PN. MPa adjusting range. MPa— 。 MPac, suitable medium: raw water, water d, medium temperature: ℃ - ℃。 Features: a, new type of adjustable pressure pneumatic valve of continuous adjustment, decompression, voltage stabilizing effect is good. Through the guide of pneumatic valve to form independent pressure feedback system, and use the principle of hydraulic control, outlet pressure is not affected by the influence of inlet pressure and flow rate and can reduce dynamic pressure, can reduce static pressure again. B, convenient operation and maintenance, just adjust the guide on the pneumatic valve adjusting bolt, can get accurate and stable outlet pressure, internal key parts adopt high quality material, dispensing with maintenance. C, large diameter, is currently the nation's largest vacuum pneumatic valve. D, pneumatic valve adopts streamlined wide-body design, flow volume is big, small resistance loss. E, can replace the middle basin, reduce the pool of land area, avoid the secondary pollution of water quality.
