Abstract
The present invention relates to a high-pressure flow rate automatic control instrument for oil-field high-pressure water-injecting and polymer-injecting process. It is formed from shell body, impeller assembly, integrating instrument, valve core assembly and velocity-reducing device. Said invention also provides their connection mode, and provides the concrete working principle and operation method of said flow rate automatic control instrument.
Description
Technical field:
The present invention relates to a kind of volume control device that is used for high oil field water injection, polymer injection technology.
Background technology:
At present, in water injection well in oil fields station pipe network and polymer injection flow process, adopt the artificial regulatory valve to regulate flow usually.Because water filling, polymer injection pipe network working medium pressure are very high, this kind flow regulation mode is operated rather difficulty, labor strength is very big when manual adjustments especially, and degree of regulation and work efficiency are lower, is unfavorable for the raising of water filling, polymer injection technological effect and economic benefit.The high pressure flow auto-controlling device of using at the scene is because its spool is a monolithic construction in recent years, and highly pressurised liquid enters the back spool each several part is produced great influence of unbalance power, causes the spool easy deformation, thereby influences the operate as normal of whole flow self-con-tained unit.
Summary of the invention:
The object of the present invention is to provide a kind of high pressure flow auto-controlling apparatus of regulating and control easy, resolution, degree of regulation and high efficiency, can alleviating labor strength.
The present invention realizes like this.This kind automatic flow controller is made up of housing, impeller combination, integrating instrument, spool combination and reduction gear, and the spool combination is housed in the housing upper chamber, and the top is fixedly connected with reduction gear, and housing one side is provided with the impeller combination, and the outside is connected with integrating instrument.This automatic flow controller integrates flowmeter, flow valve, controller three, adopts the AC and DC power supply, can be manually, automatic dual-purpose.During use, it is installed on water filling or the polymer injection pipeline, when water under high pressure or polymkeric substance are flowed through housing, drives the wheel rotation in it; The electromagnetic signal that sensor obtains is directly read the aggregate-value and the instantaneous value of flow through integrating instrument; Then, integrating instrument provides regulating command according to setting value, and lead transfers to motor and by the driven by motor reduction gear, spool is combined in the reduction gear drive and is regulated down and then to flow.Because spool is a split-type structural, spool and valve rod are clearance fit, its top is provided with relief chamber, and highly pressurised liquid enters relief chamber through the spool pressure-reduction outlet, full of liquid in the chamber, make the upper and lower equalization of pressure of spool, because of the spool outlet is provided with pressure-reduction outlet, makes also stress equalization of its front and back, thereby can not be out of shape again, valve rod can rotate easily, keeps good working order.Owing to be provided with reduction gear in this device, thereby manual adjustments is also simple and laborsaving.
High pressure flow auto-controlling apparatus installation provided by the invention, use, easy to maintenance, reliable operation, resolution and degree of regulation height, antijamming capability is strong, utilize that it can be stablized, regulating flow accurately in high pressure water injection, polymer injection process, alleviate labor strength, improve the technological effect and the work efficiency of water filling, polymer injection, be suitable for and apply.
Description of drawings:
Fig. 1 is a general structure synoptic diagram of the present invention.Fig. 2 is this auto-controlling apparatus spool built-up section structure and principle of work synoptic diagram.Fig. 3 is Fig. 2 A-A sectional view, and the front direction is meant fluid pressure distribution situation in the valve in the chamber, and number in the figure " 6 ", " 7 " are respectively the liquid-inlet and the outlet of valve pocket, and label " 8 " is the equalizing port on the spool, and label " 9 " is a relief chamber.
Embodiment:
The present invention is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the present invention is made up of housing 1, impeller combination 2, integrating instrument 3, spool combination 4, reduction gear 5, its structure, assembled relation are as follows: spool combination 4 is housed in housing 1 upper chamber, the top is fixedly connected with reduction gear 5, housing 1 one sides are provided with impeller combination 2, the outside is connected with integrating instrument 3, and integrating instrument 3 signal instruction output terminals are connected with the motor of reduction gear 5 by placing the lead in the flexible pipe.Wherein, housing 1 is made of with being connected with flange disk two parts body of work parts chamber, and two parts are orthogonal, and body of work parts chamber top is provided with the circular groove that holds spool 4, bottom one side opening makes up 2 chambers with impeller and communicates, and disk limit portion is uniformly distributed with 8 screws along the circumference.Impeller combination 2 is made up of impeller, impeller support and axle.Integrating instrument 3 integrates flowmeter, two functions of controller, is made up of sensor 3-1, LCD panel 3-2, MSP430 chip and auxiliary electron element, and is fixed on the outside of housing 1 one lateral lobes wheel combination 2 with fixed support 3-3 and bolt.Spool combination 4 (is seen Fig. 2, Fig. 3) by valve rod 4-1, thrust bearing 4-2, valve pocket 4-3 and spool 4-4 form, the valve rod 4-1 outside is provided with thrust bearing 4-2, in order to reduce its axial friction, the lower end is connected with the square hole at center, spool 4-4 upper end in placing valve pocket 4-2 by tetragonal body, spool 4-4 is provided with the equalizing port 8 relative with valve pocket 4-2 one side outlet, thereby can reduce radially friction, the relief chamber 9 that constitutes between spool 4-4 top and the valve pocket 4-2, can play the effect that reduces axial friction, thereby make about the spool, front and back all stress equalization can not be out of shape, and valve rod can easily rotate.Reduction gear 5 is by worm gear 5-1, worm screw 5-2, bearing 5-3, casing 5-4 and place the motor 5-5 of casing 5-4 both sides and handwheel 5-6 to form.
