SELF-CONTAINED VALVE EQUIPPED WITH TEMPERATURE-SENSITIVE DEVICE Russian patent published in 2016 - IPC E21B43/12 E21B43/24 

FIELD: mining.

SUBSTANCE: group of inventions relates to mining and can be used for regulation of inflow to production pipeline. A valve or flow control device for control on basis of Bernoulli effect, fluid flow from one area or region to another, in particular for controlling flow of fluid, such as oil and/or gas containing water from oil or gas reservoir in mining wells pipeline oil and/or gas reservoir, from inlet on inlet side to outlet side of device at outlet. Valve comprises a movable valve element configured to actuation temperature sensitive device. Valve gate is made with possibility of its movement sensitive to temperature device in closing direction in response to excess of specified value of temperature of fluid surrounding valve and/or incident inside valve. Valve device is designed so that temperature sensitive device comprises an expanding mechanism, which is a sealed structure at least partially filled with expandable material. Said expandable material, and therefor said expanding mechanism, are configured to, in excess of a predetermined value of fluid temperature to expand and thereby cause movement of movable valve shutter in closing direction. Valve has a passage of flow from inlet to outlet, a portion of which directs fluid flow along surface of movable valve shutter so as to be capable of autonomous movement of movable valve shutter control based on Bernoulli effect said fluid flow when movable valve element is not moved temperature-sensitive device in direction of closure.

EFFECT: technical result is to improve efficiency of control of pipeline flow.
