DEVICE FOR INHIBITOR'S SUPPLY Russian patent published in 2017 - IPC E21B37/06 

FIELD: mechanical engineering.

SUBSTANCE: device comprises a container with an inhibitor, a hollow tube, one end of which is immersed into the inhibitor, and the other - is mounted into the inlet vessel and is fluidly connected with the outside space. At the bottom of the container has the metering orifice, providing outward leakage of inhibitor. Above the metering orifice within the container flow control inhibitor node is located, at which the loss of energy flow occurs. The flow control unit is made as two sets of oppositely directed upper and lower cylindrical walls with opposite ends, which are hermetically sealed and form a circumferential gap between the open end.

EFFECT: uniformity of inhibitor flow into the bedded fluid, and increasing the reliability of the whole.
