Controlled throttle relates to the field of oil-gas production, in particular to means intended for control and setting mode of operation of gusher and gaslift wells. Design of throttle with hollow throttle ring arranged with several profile channels and convex outer surface conjugated with guide of support disc in concave shape arranged with opening, for instance in elliptical shape, proposed makes it possible to provide in process of operation of the throttle to provide wide range of smooth reliable stepless throttling of product flow at outlet line of well and to decrease hydro-abrasive wear of inlet and through channels of the throttle. |
