Then depends on stem and the adjustment of the control system, make the flap valve after pressure and spring force equilibrium, the valve after pressure in a certain error range to maintain fixed eternal. Q: a: reduce the pressure valve structure to reduce pressure valve ownership semi-automatic valve, high-pressure oxygen cabin air pressure is higher than 0. Reduce the pressure valve shall be set up 8 MPa. 。 Mainly by the valve body, valve cover, piston, spring, the main valve, the deputy valve and diaphragm. 'Marine valve structure: high-pressure oxygen cabin air reduces the pressure valve more right and using piston type to reduce the pressure valve, its structure is shown in figure 4 7. Reduce pressure valve with compressed air to the own + 羭 strand, the outlet pressure semi-automatic keep safe. Reduce the pressure valve is a regulation, reduced the inlet pressure to a certain demand of outlet pressure, and to rely on the media itself can + 羭 strand, make the outlet pressure semi-automatic maintain safe valve. Power flow from the body of learning point of view, can reduce the pressure valve is a part of the resistance change of throttling element, namely after change throttling plane or the size of the object surface, make the change in velocity and kinetic energy of the fluid, result in different pressure loss, thus to achieve goals to reduce pressure. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
