GAS PRESSURE REGULATOR

The proposed gas pressure regulator can be used in diverse pneumatic systems. The regulator contains a casing, a rotary damper with a pneumatic actuator, and a control unit for the pneumatic actuator. The actuator contains a bellows-sealed element with a movable sleeve and a rod, which is coupled with the sleeve by threaded joint that allows the position of the rod relative to the sleeve to be adjusted. The sleeve is coupled with the inside end surface of the bellows-sealed element via a spring. The rod is coupled with a lever that is fixed to the shaft of the damper. The shaft of the damper is supported by roller bearings with seals. The bellows-sealed element moves between guide rollers, which are installed in a ring that can move along the longitudinal slots of the casing without turning. The proposed design of the pressure regulator ensures the stability of the regulator in dynamic modes and the smoothness of movement of movable parts of the pneumatic actuator.
