Abstract
The utility model relates to a constant flow water tap which is composed of a water inlet regulating hole, a water outlet hole, an outer sleeve of the water tap and an outer shell of the water tap, wherein the outer shell of the water tap is fixed in the outer sleeve of the water tap. The water inlet regulating hole and the water outlet hole are arranged on the outer shell of the water tap. The utility model is characterized in that a slide valve with a cross section like a Chinese character 'gan' is arranged in the inner cavity of the outer shell of the water tap. Two horizontal lines of the slide valve are vertical to the outer shell of the water tap and are respectively arranged on both ends of the water inlet regulating hole and the water outlet hole, so that a cavity communicated with the water inlet regulating hole and the water outlet hole is formed between the two horizontal lines of the slide valve. A regulating pressure spring is sheathed on a vertical line between lower horizontal line of the slide valve and the outer shell of the water tap. The utility model successfully realizes adjustable constant flow in differential pressure with a variation range of 0.5-17MPa 20-100m< 3 > per day, and has accuracy of about 5% and service life of 10000 hours obviously advantage over 1500 hours of like products in China.
Description
Technical field
The utility model belongs to a kind of water nozzle that is used for the different oil reservoir layered quantitative water filling of same oil well, is a kind of Constant flow water tap specifically.
Background technology
Along with continually developing of China's oil mineral reserve, the nature gusher is fewer and feweri, in order to improve oil recovery efficiency and to avoid fault sag, must be to the different oil reservoir layered quantitative water filling of same oil well, the common water nozzle of present most of Oilfield using supplies water, because the variation of hydraulic pressure, strata pressure makes common water nozzle can't guarantee stable design water injection rate, and directly influencing the quality and the output of recovering the oil, Constant flow water tap is exactly for satisfying the quantitative injection device of this market demand.The acquired patent of the applicant " the Constant flow water tap " (patent No.: 02229078.8) supply water its complex structure though can satisfy constant current.
Summary of the invention
The purpose of this utility model provides a kind of precision height, long, simple in structure Constant flow water tap of life-span, to overcome above-mentioned deficiency.
To achieve these goals, the utility model is by the water inlet adjustment hole, weep hole, water nozzle outer sleeve and water nozzle shell constitute, wherein the water nozzle shell is fixed in the water nozzle outer sleeve, water inlet adjustment hole and weep hole are arranged on the water nozzle shell, be characterized in: also be provided with the guiding valve of a cross section for " doing " font at the water nozzle shell inner cavity, " do " two horizontal lines of font guiding valve and be separately positioned on into water adjustment hole and weep hole two ends perpendicular to the water nozzle shell, make to form the water adjustment hole cavity identical between two horizontal lines of " doing " font guiding valve, be with the adjusting stage clip on the vertical line between horizontal line and the water nozzle shell under " doing " font guiding valve with weep hole;
The water nozzle shell of horizontal line region is provided with cushion hole under above-mentioned " doing " font guiding valve.
The utility model has successfully been realized in pressure reduction 0.5～17MPa excursion, every day 20～100m
3Adjustable constant flow rate, precision can reach ± and 5%; The utility model life-span is 10000 hours, obviously is better than domestic 1500 hours life-span of like product.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: 1-cushion hole, 2-water nozzle outer sleeve, 3-water inlet adjustment hole, 4-regulate stage clip, 5-water nozzle shell, 6-guiding valve, 7-weep hole, 8-constant voltage chamber.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing.
The utility model as shown in drawings, water enters constant voltage chamber 8 by water inlet adjustment hole 3, flows out by weep hole 7 because weep hole 7 areas are certain, as long as constant voltage chamber 8 internal pressure P2 are stable, then water flow P3 is constant.
When intake pressure P1 increases, therefore hydraulic pressure P2 in the constant voltage chamber 8 also increases, this moment, flow increased, because the hydraulic pressure P2 in the constant voltage chamber 8 increases, hydraulic pressure P2 overcomes adjusting stage clip 4 thrusts promotion guiding valve 6 and moves to left, " do " on the font guiding valve 6 horizontal line and make into that water adjustment hole 3 areas reduce, the hydraulic pressure P2 pressure in the constant voltage chamber 8 are reduced, flow returns to normal value; Otherwise, when intake pressure P1 reduces, therefore hydraulic pressure P2 in the constant voltage chamber 8 also reduces, this moment, flow reduced, because the hydraulic pressure P2 in the constant voltage chamber 8 reduces, guiding valve 6 moves to right under adjusting stage clip 4 promotes, and making into, water adjustment hole 3 areas strengthen, hydraulic pressure P2 pressure in the constant voltage chamber 8 increases, and flow returns to normal value.
Be designed to water inlet adjustment hole 3 flat, can increase the susceptibility of flow to guiding valve 6, that is, 6 needs of guiding valve change by a small margin, the area of water inlet adjustment hole 3 will change significantly, like this, it is very little to regulate stage clip 4 stroke in adjustment process, can think that it is constant regulating stage clip 4 tension force, have only pressure left that the hydraulic pressure P2 in constant voltage chamber 8 produces with adjusting stage clip 4 thrust equal and opposite in directions, when direction is opposite, reach balance, at this moment constant voltage chamber 8 internal pressure P2 are constant, and weep hole 7 captured areas are certain, so just guaranteed that output flow P3's is constant.
The effect of the utility model cushion hole 1 is to make the pressure of regulating stage clip 4 place cavitys consistent with the pressure of output flow P3.
