PRESSURE REDUCING VALVE Russian patent published in 2024 - IPC G05D16/08 F16K17/06 

FIELD: pipeline fittings.

SUBSTANCE: invention relates to pipeline valves, namely to “downstream” fluid pressure regulators. Pressure reducing valve comprises a housing made with a through cavity and an inlet union for connection to a pipeline, slide valve installed with possibility of longitudinal movement in housing, spring located in support with possibility of interaction with slide valve with compression in direction of slide valve movement, spring support located inside the housing with possibility of longitudinal movement and also made with through cavities, and an outlet union for connection to the pipeline on the side opposite to the housing location. Valve housing is cast, the inlet union is equipped with a divider having a cone-shaped shape, and the slide valve placed in the housing has drop-shaped milled grooves located along the slide valve axis. At that, support bushing, having outlet pressure marking, includes adjusting bushing containing trapezoidal thread and spline used as outlet pressure indicator.

EFFECT: invention is aimed at creation of a pressure reducing valve of increased reliability and durability, having minimum overall dimensions, having no requirements for working medium purity, operating at unstable change of inlet pressure and excluding the possibility of unauthorized adjustment.
