The utlity model has following beneficial effect: this gathers, and expelling water drives electronic adjustable water nozzle because employing water nozzle bottom is a bellmouth, and water nozzle upper end outer ring groove has been built in the outer shroud sealing ring, and water nozzle lower surface outer ring groove has been built in end-face seal ring; There is screen pack the interior lower end of water inlet short circuit, and water inlet short circuit outer ring groove is built-in with the thread seal circle in the middle extend neck lower end, and the water inlet short circuit has exterior seal ring outside the middle part; Middle extend neck has annular groove outside the upper end; The weep hole of 46 mm wide 18 millimeters long is arranged at middle extend neck top; The plunger lower end conical surface places in the current stabilization chamber in the extend neck under the weep hole lower edge; In extend neck weep hole place external diameter be that 19.5 millimeters internal diameters are 14.5 millimeters, spring is set upright the structure that sealing ring is arranged inside and outside the pad.Utilize the water nozzle bottom to reduce the stuck phenomenon generation of plunger for bellmouth and screen pack.Utilizing spring to set upright has inside and outside the pad sealing ring, outer shroud sealing ring, face sealing ring, thread seal circle and exterior seal ring to improve sealing effectiveness, reaches no wastage.In the utilization there be 46 mm wides, 18 long weep holes to eliminate to throw partially and play phenomenon up and down extend neck top.Utilizing current stabilization chamber and external diameter is that 19.5 millimeters internal diameters are 14.5 millimeters middle extend neck, and extend neck wall thickness in the increase prolongs this and gathers expelling water and drive electronic adjustable water nozzle application life.This gathers expelling water and drives electronic adjustable water nozzle and have water nozzle to be difficult for thorn bad thus, and good sealing effect is transferred characteristic of accurate with surveying, and does not have the inclined to one side problem of throwing.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Extend neck among the 1-among the figure, 2-water nozzle, the 3-short circuit of intaking, 4-outer shroud sealing ring, the 5-screen pack, 6-thread seal circle, the 7-weep hole, the 8-exterior seal ring, the 9-end-face seal ring, the 10-plunger, the 11-spring is set upright pad.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
Shown in accompanying drawing, this gathers expelling water and drives electronic adjustable water nozzle and on existing water nozzle basis, improve.This gathers expelling water and drives electronic adjustable water nozzle and comprise into water short circuit 3, water nozzle 2 and middle extend neck 1.Water nozzle 2 is aircraft bearing steel matter, or is the wolfram steel material, or is the zirconia ceramics material; Water nozzle 2 outsides are coated fluid sealant and are placed in extend neck 1 bottom, and extend neck 1 lower end during fluid sealant is connected on water inlet short circuit 3 screw threads scribbles fluid sealant respectively by the screw thread on water nozzle 2 outsides and water inlet short circuit 3 tops and forms the 5th road; The wall thickness of middle extend neck 1 lower end is 2.2 millimeters; The thickness increase has improved intensity, adds totally five road seal approach assurances and does not leak water, and has avoided the generation of screw thread thorn leakage problem.Water nozzle 2 bottoms are bellmouth, are cooperated by the plunger of bellmouth with the lengthening tapering, and adding water outlet short circuit 3 interior lower ends has screen pack 5, is filtered out impurities by screen pack 5, reduces the plunger stuck phenomenon.Water nozzle 2 outer ring grooves have been built in outer shroud sealing ring 4, by carrying out the sealing of first road between 4 pairs of water nozzles 2 of outer shroud sealing ring and the middle extend neck 1.Water nozzle 2 lower surface outer ring grooves have been built in end-face seal ring 9, carry out the sealing of second road by 9 pairs of water nozzle 2 lower surfaces of end-face seal ring and water inlet short circuit 3 front end faces, realize leakproof.There is screen pack 5 lower end in the water inlet short circuit 3, is filtered out impurities by screen pack 5, reduces plunger 10 stuck phenomena.Water inlet short circuit 3 outer ring grooves are built-in with thread seal circle 6 in middle extend neck 1 lower end, the sealing in strengthening by thread seal circle 6 between extend neck 1 and water inlet short circuit 3 steps, and the minimizing leakage, this is a three seals.The water inlet short circuit has exterior seal ring 8 outside 3 middle parts, and the sealing by exterior seal ring 8 strengthens between water inlet short circuit 3 and the injection well downhole flow regulator seating nipple reduces leakage, and this is the sealing of the 4th road.Outside middle extend neck 1 upper end annular groove is arranged; The weep hole 7 of 46 mm wide 18 length is arranged at middle extend neck 1 top; Owing to adopt the weep hole 7 of 46 mm wide 18 length; No matter how to throw in and throw the back up and down play this gather expelling water and drive electronic adjustable water nozzle, can both guarantee that the water yield of weep hole 7 is constant, guaranteed the accuracy of the test water yield.The plunger 10 lower end conical surfaces place in the current stabilization chamber in the extend neck 1 under the weep hole lower edge; Flow to by current stabilization chamber stationary flow; Can avoid the rotation of tapered plunger, take cone-shaped plunger, guarantee that water nozzle 2 and plunger 10 are not bad by thorn along the optimizing structure of water (flow) direction regulating pondage.Middle extend neck 1 weep hole 7 place's external diameters are that 19.5 millimeters internal diameters are 14.5 millimeters; Internal diameter and external diameter difference by middle extend neck 1 learn that middle extend neck 1 weep hole 7 wall thickness increase, and then have increased intensity; Add totally five road seal approach assurances and do not leak water, avoided the generation of screw thread thorn leakage problem.Final prolong this and gather expelling water and drive electronic adjustable water nozzle application life.Plunger 10 is aircraft bearing steel matter, or is the wolfram steel material, or is the zirconia ceramics material, and spring has sealing ring inside and outside setting upright pad 11, realizes that weep hole top is water-tight.
The said structure optimized Measures; Form the sealing of first road by the outer shroud sealing ring 4 between water nozzle 2 and the middle extend neck 1; Water nozzle 2 lower surfaces are formed the sealing of second road with water inlet short circuit 3 front end faces by end-face seal ring 9; Thread seal circle 6 by between extend neck 1 in strengthening and water inlet short circuit 3 steps is formed three seals; Exterior seal ring 8 by between water inlet short circuit 3 and the injection well downhole flow regulator seating nipple is formed the 4th road, scribbles fluid sealant respectively by the screw thread on water nozzle 2 outsides and short circuit 3 tops that intake and forms the 5th road, and this 5th road seals to reach does not have wastage except that water nozzle.The easy thorn of weep hole that has the adjustable water nozzle of an existing weep hole regulating pondage is bad, the sealing effectiveness difference is leaked; Scurry up and down that surveying is out of tune and leak four problems that influences the water filling qualification rate and all be able to solve, be equivalent to improve the water filling qualification rate and survey accent efficient with the screw thread thorn.Prolong this simultaneously and gathered expelling water and drive electronic adjustable water nozzle application life, practiced thrift the product cost.
