200X pressure reducing valve
|Product model:||200X pressure reducing valve|
|Product features:||With a self guided control valve 200X valve, no other devices and energy, maintenance is simple, accurate pressure control, pressure and flow of imports by a small, reliable vacuum regulator. This series of valve products are widely used in high-rise building, living area and other water supply pipe network system and urban water supply project.|
|200X pressure reducing valve details:|
200XPressure relief valveIt is a kind of regulation and control of pipeline pressure by using the energy of the medium itselfIntelligent valve。200XPressure relief valveFor domestic water supply, fire protectionThe outlet pressure of the main valve can be regulated by adjusting the pressure reducing pilot valve in water supply and other industrial water supply systems. The outlet pressure is not due to inlet pressure and inlet flow rateChange and change,Safely and reliably maintain the outlet pressure at the set pointThe setting value can be adjusted according to the requirement to achieve the purpose of reducing pressure. The valve is decompressed accurately,It has the advantages of stable performance, safe and reliable, easy installation and long service life.
Two,200XStructure characteristics and application of pressure reducing valve
200XVacuum Regulator ValveThe hydraulic control system is composed of main valve, pilot valve, needle valve, ball valve, micro filter and pressure gauge. When used, the outlet pressure can be maintained automatically when the outlet pressure is adjusted.
200XVacuum Regulator ValveutilizePilot valve self controlIt doesn't need other devices and energy. It's easy to maintain,High accuracy of pressure controlIt is affected by inlet pressure and flow rate, and the pressure reducing and voltage stabilizing is reliable.
200XVacuum Regulator ValveProducts are widely used in high-rise buildings, living areas and other water supply network system and urban water supply project.
Three,200XWorking principle of pressure reducing valve
When the valve enters the water supply from the inlet, the water flows through the needle valve into the main valve control chamber, and the outlet pressure acts on the pilot valve through the conduit. When the outlet pressure is higher than the setting value of the pilot valve spring, the pilot valve is closed. The control room stops draining,At this point, the main valve controls the chamber pressure rising and closing the main valve, and the outlet pressure is no longer rising。
200XVacuum Regulator ValveWhen the outlet pressure drops to the setting pressure of the pilot valve spring, the pilot valve is opened and the control room is drained downstream. The pressure of the main valve control chamber is decreased because the drainage amount of the pilot valve system is larger than that of the needle valve. The inlet pressure makes the main valve open. In steady state, the inlet and drainage of the control room are the same, the opening of the main valve is constant, and the outlet pressure is stable.
Adjust the guide valve spring to set the outlet pressure.
