Adjustable pressure reducing valve series pressure problem, not a common phenomenon, is also wrong, may be present as a use, we still need a good understanding, and to control the reason analysis and processing ability, in the process of using adjustable why can present series pressure reducing valve to be the problem? Section of pipeline rupture after because of the pressure reducing valve, close the P1 valve or repair, pumping A pump stop, incurred after the valve pressure reducing valve section after the water pressure is low and the atc. Section before back to normal water supply, the pressure reducing valve suddenly opened the pump or the pump to open A valve, relief valve section before the rapid increasing pressure, adjustable relief valve section before and after the section between the in A short period of time there is A big pressure difference, pressure reducing valve doesn't work, pressure reducing valve on cavity pressure is small, is driven by the pressure of the larger pressure reducing valve is forced open, cause pressure tends to equilibrium before and after the pressure reducing valve, pressure reducing valve failure, short string of pressure. Now that was presented, and how to deal with? The following summarizes three kinds: 1, based on the working principle of the pressure reducing valve installed a relief valve after pressure reducing valve, when the pressure reducing Industrial Valves after pressure is higher than the P2, it opened the relief valve pressure, maintain normal supply pressure of a village. 2, through other ways to shorten the time series of pressure, make it close to zero. 3, according to the working principle of adjustable pressure reducing valve, proper increase of pilot valve and pipe diameter, inferior vena to arrive at a lower pressure equilibrium time, so that tends to zero time lag. Through theoretical research, described above, the second plan is one of the largest, the most economical, applicability to through the drain valve, hasten to turn over, make diaphragm chamber pressure is greater than the inferior vena, prompted adjustable pressure reducing valve swiftly back to normal. Time series of pressure of 0.
Collectively, the effect of double flanged gate valve on industrial society has been to eliminate y gate valve and drastically reduce the time long associated with resilient gate valve.
