FIELD: machine building.SUBSTANCE: gas pressure control includes an actuator equipped with a gate made from elastic material, a seat, inlet, outlet and control chambers; a throttle, a setting device with a control valve, a membrane unit and an adjustment mechanism. At that, inlet chamber of the actuator is connected through the throttle via a channel to the control chamber, the setting device and the outlet chamber. According to the proposal, the control includes a matching unit consisting of a chamber for gas cleaning from mechanical impurities and humidity; pneumatically operated shutoff and control device of normally open type; at that, throttle is built into the matching unit between gas cleaning chamber and shutoff and control device, and gas cleaning chamber is located on the side of inlet chamber, and setting device is connected to the shutoff and control device and outlet chamber.EFFECT: improving operating characteristics.9 cl, 4 dwg |
