The role of compressed air filter relief valve and the basic performance

Filter, relief valve and oil mist detector pneumatic sanlian pieces. The oil mist detector is responsible for the back-end components for oil lubrication. Generally, oil mist is used to much, because there are a lot of products can be done without oil lubrication, there is no need for oil service.

A, the role of compressed air filter:

Remove the solid impurities contained in the compressed air, water and oil drops, can’t remove the gas oil and water. According to filter drainage way, manual displacement. When there is no air pressure type automatic drainage according to the state of drainage, a normally open and normally closed.

Second, the role of the pressure reducing valve:

Pressure reducing valve is a kind of USES the energy of medium to adjust and control line pressure intelligent valve, pilot valve with stress through regulating valve, can adjust the outlet pressure of the main valve. Outlet pressure does not change due to the change of inlet pressure, inlet flow, safe and reliable ground to set the outlet pressure at planting, and can according to need to adjust the Settings to achieve the purpose of decompression.

Three, the basic properties of the pressure reducing valve:

(1) regulating range: it refers to the pressure reducing valve output pressure P2 adjustable range, meet the precision within the scope of this requirement. Regulating scope mainly related to pressure regulating spring stiffness.

(2) 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 the pressure reducing valve, the better. The output pressure must be less than the input pressure - fixed value just basically don’t changes over the input pressure.

(3) flow characteristic: it is to point to the input pressure, timing, output pressure along with the change of output flow g change 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.
