FIELD: machine building.
SUBSTANCE: invention refers to piping valves and can be used to control the flow rate and pressure of working medium (fluid, gas or steam) in systems of machine-building, chemical, gas industry and other industries. Pressure regulator consists of housing with inlet and outlet branch pipes, discs mounted in it and drive. Housing of pressure regulator is mounted in steam supply pipeline and made in the form of hollow cylinder in the plane of which on its internal surface and symmetrically to longitudinal axis of steam supply pipeline there rigidly fixed are two discs at least with two openings made in each of them for steam passage, and two turning discs mounted on the drive shaft and provided with corresponding openings are connected to them on their outer side. Drive shaft in central part between turning discs has larger diameter with formation of support ends for turning discs, which provide the limit stop for movable discs, and installation of adjusting plates.
EFFECT: increasing valve controllability and providing its long-term and reliable operation.
