FIELD: mechanical engineering. ^ SUBSTANCE: proposed pressure regulator contains housing with pressure control unit including spring-loaded twin with shutoff members and movable partition with controlling and controlled spaces. First valve interrupts communication of controlled space with feed main line, and second valve, whose shutoff member interacts with seat on movable partition, interrupts communication of controlled space with atmosphere. Second valve is rigidly coupled with first valve. Second valve is furnished with spring-loaded valve head with shutoff member secured on rod of second valve for displacement in longitudinal and cross direction relative to valve axis. Cup for movable valve head is arranged on rod. Valve head is pressed by spring arranged between bottom of cup and inner blind hole of movable valve head. Displacement of head is set by displacement limiter. ^ EFFECT: prevention of influence of self-sustained pressure fluctuations, provision of stability of pressure regulation. ^ 2 dwg |
