ControlAir康气通 TYPE100精密减压阀图纸资料说明: The measuring capsule in the Type 100 is the sensing element thatcontrols a high precision, balanced servomechanism. Stainlesssteel alloy construction gives the measuring capsule the ability tomaintain forces over long periods of time without hysteresis. Thiseliminates problems associated with regulators that are controlledby a range spring. The downstream regulated pressure fills thecontrol chamber and surrounds the measuring capsule. Expansion,contraction, or other slight movement of the capsule causes thepilot valve to open or close. This creates a substantial pressurechange within the pilot pressure chamber. The change in pilot pressure is directly proportional to the downward force on the pilotdiaphragm which causes the appropriate movement of the supplyvalve or relief valve and corrects any variation from set pressure.The high gain nature of this servomechanism allows the Type 100to react to changes in set pressure as little as 0.01 psig.Regulated pressure applies an upward force on the underside ofthe control diaphragm. When set pressure drifts above the set pointthe control diaphragm assembly moves upward and allows excesspressure to be vented out of the relief valve to atmosphere. Thedesign of the relief valve permits substantial reverse flow capacitywhich quickly exhausts system back pressure thus eliminating theneed for a separate relief valve. The Type 100 is a high precision, multi-stage pressureregulator. Thispressurecontrollerprovides the highestlevel of regulation accuracy and repeatability available.The Type 100 is ideal for applications that call for theutmost in control and maximum stability under variableoperating conditions. A stainless steel measuring capsule isused as a sensing element to activate the high gain servobalanced control mechanism in which the main valve iscontrolled by a pilot valve. This allows for greater accuracyand eliminates many of the problems associated with conventional regulators using range springs and diaphragms
