Technical field
The utility model relates to the polymer solution flow control valve.
Background technique
Avoid fall glutinous to polymer solution in order to adapt in the tertiary oil production in oil field notes polymerizing technology process, streamline radial contraction when adopting Newtonian fluid by conical contraction mouth, and macromolecule polymer solution (600~5000mg/L) present tube wall circulation when flowing through the taper contraction mouth, big tens of times of the Newtonian fluid of the equal viscosity of pressure drop ratio of contraction mouth, at the frictional resistance of contraction mouth also greater than its frictional resistance that in pipe, flows, therefore as long as the control shear rate is no more than critical condition (flow adjustment range 0~100m 3/ h) just can promptly control flow velocity and realize polymer solution shear-free flow amount by the control step-down, keep viscosity.
The model utility content
The purpose of this utility model provides a kind of high low pressure shear-free flow adjustable valve.
The technical solution of the utility model adopts valve seat, valve body, valve pocket, spool, support, axle, leading screw, nut, thrust-bearing, supported flange, worm gear, pressure cap, worm screw, handwheel are located by connecting; It is characterized in that valve seat top has taper hole shape spool bore to communicate with runner, valve seat two ends dress seal ring and outlet(discharge) flange sealing, valve seat and outlet(discharge) flange dress seal ring and valve seal; Valve body is a cylinder that stepped inner chamber is arranged, and its upper end connects support, and the lower end connects valve seat and outlet(discharge) flange; The pressure balance chamber of one groove shape is arranged in the middle of the inner chamber of valve pocket, and valve pocket is embedded in the inner chamber of valve body, and the bore seal of equipped two seals circle and valve body; The core print of spool bottom becomes coniform, and coniform end of body is the sphere core print, and this core print radius and runner radius match, and spool is contained in the inner chamber of valve pocket, and dress seal ring and valve pocket bore seal; The spool upper end connects the axle that is located by connecting, the valve pocket inner chamber top dress seal ring and the shaft sealing that is located by connecting; Hold leading screw in the support, leading screw connects spool by the axle that is located by connecting, and the support upper end-hole is adorned thrust-bearing, nut and supported flange successively, nut and leading screw assembling, and the nut bottom has protruding dish to be embedded between two thrust-bearings; Worm gear and pressure cap are fixed on nut top, adorn worm screw on the support on worm gear side side; There is handwheel the end of worm screw.
The utility model has the advantages that volume is little, easily assembling is easy to maintenance.It is low to be used for tertiary oil production in oil field notes polymerizing technology process cost, instant effect, and the control flow rate size makes viscosity retention rate height, can satisfy different flow, the needs that the polymer solution flow of different pressures is regulated.
