Comprehensive analysis of water reduced pressure principle of pneumatic valve, manifold pressure pneumatic valve, import relief pneumatic valve advantages

the OR water reduced pressure pneumatic valve pneumatic valve is a kind of special device, reduce the working pressure pipeline automatically, it can be pneumatic valve before pipeline of high pressure to reduce to the pneumatic valve pipe after the required level. Reduced pressure pneumatic valve is widely used in high-rise buildings, the area of urban water supply pipe network pressure is too high, mines and other occasions, to ensure the water supply system in the water points to obtain the appropriate service water pressure and flow rate. In view of water leak rate and degree of waste almost as the water pressure is directly proportional to the size of feed water system, thus reduced pressure pneumatic valve have improve system operation condition and potential water-saving effect, Italy OR water pressure pneumatic valve according to statistics, the water saving effects about %.

basic properties ( Regulating range: it refers to that the adjustable limit of the reduced pressure pneumatic valve output pressure P, within the scope of the requirements of vacuum pneumatic valve to the specified precision. Regulating scope mainly related to pressure regulating spring stiffness.
　　( Pressure feature: it refers to the flow fixed value for g, caused by the input pressure fluctuation characteristics of the output pressure fluctuations. The smaller the output pressure fluctuation, the characteristics of vacuum pneumatic valve, the better. The output pressure must be less than the input pressure - Constant value was basically not changes over the input pressure.
　　( Flow feature: it refers to the input pressure - Timing, the output pressure changes along with the change of output flow g resistance. G when the flow changes, the output pressure changes as small as possible. Generally the lower the output pressure, which fluctuates according to the change of output flow.
imported Italian OR water pressure pneumatic valve in detail
Italy OR water pressure pneumatic valve is widely used in high-rise building, the director of the reduced pressure, in the case of local high pressure OR sudden pressure, protect the following life, production equipment, with water OR water pressure pneumatic valve series consists of the following products, economical manifold vacuum pneumatic valve, piston manifold pressure pneumatic valve, diaphragm manifold pressure pneumatic valve, pneumatic valve, high pressure pipe pressure OR water pressure pneumatic valve reduce dynamic pressure and static pressure, reduce export pressure stability without fluctuation, small size, high cost performance, choose the OR water pressure pneumatic valve is to choose quality.
water pressure pneumatic valve installation:
. Water pressure pneumatic valve can be installed in horizontal or vertical flat line;
. The installation of water pressure pneumatic valve must be in strict accordance with the aerodynamic direction of the arrow on the valve body to keep and fluid flow in the same direction, if the water is not clean some impurities, must be installed in the reduced pressure of the pneumatic valve upstream water inlet filter.
. Open water, and reduced pressure pneumatic valve adjusting export pressure adjusted with a word screwdriver, clockwise rotation screwdriver outlet pressure, and outlet pressure decreases, and cooperate with pressure gauge to adjust, until met the requirement of the outlet pressure value;
. Water pressure pneumatic valve in the pipeline of the check, in order to prevent the harm of water hammer, also can be installed small expansion water tank, prevent damage pipelines and pneumatic valves, the filter must be installed in front of the reduced pressure pneumatic valve's inlet pipe, and the expansion tank must be installed in water after decompression pneumatic valve outlet pipe;
. If you need to water pressure pneumatic valve installed in the hot water system, must be installed between the reduced pressure pneumatic valve and expansion tank check pneumatic valve. Both to expansion tank to absorb the increase due to thermal expansion of the volume of water, also can prevent the reverse flow of hot water or pressure fluctuation influence on vacuum pneumatic valve, to ensure that the pneumatic valve normal work for a long time.
