Automatic Flow Control Valve for Water injection used in the secondary Recovery of oil wells

摘要

Automatic Flow Control Valve for Water injection used in the secondary Recovery of oil wells, the adaptable into a Side Pocket mandrel plug in the pipe.The Body of this Valve comprises a Cylindrical Body (10), a Lower terminal Body (60) with holes (61 - 62) for water inlet, and an intermediate Joint comprising a First tubular segment (20) fixed to the lower terminal Body (60) and equipped with a Shutter at Ntiretorno (80), Second, Third and Fourth related tubular Segments (30,40 and 50) Fixed coaxially with the first (20), Defining the shirt of a Shaft (90), which has an axial DUCT (91) Equalizer which is connected with an axial Chamber (51) of the Fourth segment tubular (50), which is confined in a Spring (52) contrast STEM (90).At the anterior end of the spindle is Mounted retentivamente (90) a piece of pressure reducing (100) that has at least one hole central Master (101).The STEM (90) has an intermediate portion (94) in the form of peripheral Step runs in a Tapered distal portion (41) of the House of the Third tubular axial segment (40), bounded by a fixed Seat (200) to the end of the Fourth segment tubular (50),Taking the Middle part (94) STEM (95) angularly arranged Passages Connecting the tube axial (91) of the Rod with the annular portion of the Chamber (41) of the Third tubular segment (40) and, through this, with side Holes (42) of water outlet of the Third Segment This tubular (40).All the components of the Valve Body have respective Peripheral rebates faceted consistent with conventional adjustment Tool.
