DEVICE FOR STABILIZATION AND PRESSURE CONTROL Russian patent published in 2019 - IPC F16L55/04 F17D1/20 

FIELD: physics.

SUBSTANCE: invention relates to devices for stabilization of flow pressure and can be used in pressure pipeline systems of various branches of national economy, in particular, in flow meters. Device comprises hollow cylindrical housing with fluid supply and discharge branch pipes annular chamber. Hollow cylindrical housing is equipped with fixed partition with hole and installed on flange joints with spherical bottoms, one of which contains liquid supply branch pipe. Circular chamber is formed by the second spherical bottom fixed in the hole of the fixed partition wall by the metal pipe, inside which the smaller-diameter metal pipe with the external semi-ring partition is installed so that during flow of liquid two equal flows are formed. Upper part of the annular chamber contains an air layer, above which the housing is provided with holes for air supply and discharge and pressure control. In lower part of annular chamber there is a liquid discharge branch pipe. Length of pipe of smaller diameter at least five times exceeds length of pipe fixed in hole of fixed partition. Axis of symmetry of fluid feed branch pipe, holes of fixed partition and metal pipes below axis of symmetry of housing by value of inner radius of pipe of smaller diameter.

EFFECT: device in this design version allows effective stabilization of pressure of pressure flow with possibility of its adjustment.
