DEVICE FOR FLOW DIRECTING FOR USE WITH FLUID REGULATORS Russian patent published in 2016 - IPC G01F1/00 

FIELD: machine building.

SUBSTANCE: invention relates to a device for flow directing for the use with fluid regulators. A fluid regulator contains a casing, having a bypass channel, a limiting throttle that by fluid is connected with an inlet hole and an outlet hole. The plunger of the valve installed in the bypass channel moves relative to the valve seat adjacent to the throttle. An actuator is functionally connected with the valve plunger, and the actuator switches a measuring chamber as per the fluid, the chamber is connected with the outlet hole of the bypass channel. The actuator moves the valve plunger relative to the valve seat to regulate the fluid flow through the throttle between the inlet hole and outlet hole as a response to the fluid pressure at the output. A flow directing element is connected to the valve plunger. The flow directing element has a weakening reducing assembly to direct the fluid passing through the throttle to the outlet hole of the bypass valve, and from the measuring chamber of the actuator during the first pressure drop on the throttle, and an amplification reducing assembly to direct the fluid passing to the measuring chamber of the actuator at the second pressure drop, where the second pressure drop is larger than the first pressure drop.

EFFECT: improved throughput capacity or accuracy class of the fluid regulator, correction of both the flow amplification characteristic and the flow weakening characteristic.
