Output the output pressure and flow of compressed air to maintain safe. 3 individual cavity of the pressure of the gas is the same. Spring 1 force is no longer at this point the cover after the valve core utility on the piston, but to make the cover the bottom of rubber gasket pressure on the pressure regulating valve mouth tightly, pathways between the input cavity and output cavity is blocked. When the outlet pressure is higher than the set pressure, overflow valve of the utility, make the outlet pressure drops to the set pressure. So security beginning and end of the outlet pressure safe in demand on the set pressure. Output cavity compressed air through the body of article 2 C and gas path entered A cavity. When the guide gas path of compressed air into the chamber, B longer serve this valve. As the output cavity pressure loss, at present, the same applies to C cavity pressure piston underside of pressure is higher than upper, piston and valve core B together along the axis up into the mobile gradually down the overflow valve mouth opening. Because the cover upper and lower side under the pressure of the atmosphere in the cancellation of the equilibrium condition, so whether the air inlet ( IN) Pressure flap, how don't can affect the pressure equalization in the valve, it can ensure the beginning and end of the outlet pressure safe in demand on the set point, pressure valve with satisfactory special properties. 3, because the valve also have special properties of pressure regulating valve and relief valve, it can at the same time for the pressure regulating valve and relief valve office, than in the gas circuit system pressure regulating valve and relief valve alone setting, system simplification, compact structure. 4, outlet pressure feedback of the valve belong to pneumatic pressure regulating the overflow valve, without a pilot signal to lose to fashion, in a normally closed condition. 5, when the output pressure is lower than the set value, the piston is greater than the upper side of the force, under the moving piston progresses, push the cover up 3, the pressure regulating valve port, the pressure regulating valve mouth into the output cavity compressed air flow rate increased, the output cavity pressure rise accordingly. The set pressure is the pressure regulating valve and relief valve mouth shut down at the same time, the valve in the outlet pressure at the static equilibrium conditions. But also eliminate the pressure regulating valve and relief valve set pressure difference between in the security system empty atmospheric pressure force can be more properly regulate and reliable in demand on the set pressure value. 6 the overflow valve when the valve core ( The end face) After contact with the valve cover 3 bottom is absolutely, output and the overflow channel is blocked. Output pressure of the high and low, by entering the pilot port CP atmospheric pressure to stem, after debugging the pressure to set the outlet pressure. If the pressure is still higher than the set value of the output cavity, the piston moves down, then still until the pressure regulating Industrial Valves mouth closed absolutely. At this point, if the output pressure is equal to the set pressure value, the piston resting movement. 。 When output pressure reached set value, the overflow valve and valve cover bottom absolute joint, between the output cavity and the overflow cavity path is blocked, the overflow of repose. 2, the valve is regulating the overflow Industrial Valves. Piston and then move up along the axis, valve core will cover up into, and made the spring on the valve cap compression, pressure regulating valve mouth was open, and the input cavity and output cavity connected input cavity compressed air through the mouth into the voltage regulator output cavity, the output port OUT. Of CP mouth into the stem compressed air chamber B, moves the pistons, along with its upward into the mobile valve core together along the axis, overcome the spring force, make its compression. 6, when output Marine valve pressure is higher than the set pressure, piston under the utility of strength is greater than the upper side, the cover and the piston moves down together, reduce the pressure regulating valve opening, the pressure regulating valve port into the output cavity flow of gas is reduced, the output cavity gas pressure drops. When the pressure reach setting of the output cavity, piston upper and lower sides of force equilibrium, piston resting up, pressure regulating valve opening remain unchanged. 7, if the output pressure is higher than the set pressure value, the piston then moves down, the overflow valve port is on the end face of valve core and valve cover 3 bottom out, output cavity and the overflow cavity connected, the output cavity gas is removed by the overflow valve port after the EX port. When the outlet pressure is lower than the set pressure, the pressure regulating valve of the utility, make the pressure rise to set. At this point, the overflow valve and pressure regulating valve opening and closing, the valve in the gas flow resting state of static equilibrium. Q: direct utility to reduce pressure on industrial valve's unique place and office principle answer: 1, the QPF - F50 type pneumatic balance valve and will reduce the pressure valve, used in pneumatic circuit, the compressed air pressure value to adjust, and make the set pressure value to fixed eternal.
