The technical solution of the utility model is：A kind of multi-functional valve type shower nozzle of liquid release, including fixed cover and outer
Set, the sleeve thread are connected to inside fixed cover, and jacket internal is equipped with movable spray head, the movable spray head vertical direction point
For upper, middle and lower segment, wherein the diameter in stage casing is less than upper and lower two sections of diameters, and the through hole C of horizontal direction is provided with stage casing,
Hypomere is placed in the through hole E of fixed cover bottom, and the through hole D of vertical direction, the outer surface of upper of epimere are provided with hypomere center
Convex edge is circumferentially with, spring is provided between convex edge bottom and fixed cover inner bottom surface；The overcoat upper surface is provided with through hole at center
A。
The external diameter of the movable spray head epimere is more than through hole A internal diameter, and the through hole D communicates with through hole C.
The utility model has the advantages that：Due to taking such scheme, the multi-functional valve type of the liquid release
Shower nozzle supports the use suitable for radioactivity logging device, its equivalent to one pressure valve, during off working state under spring force effect
Through hole A is blocked, and avoids traced fluid seepage；Moving down by movable spray head during work, traced fluid passage is formed, and work as through hole
When C or through hole D is blocked, movable spray head moves down to form second channel, is blocked so as to avoid avoiding shower nozzle, solves release institute
The traced fluid seepage and sprayer channel carried blocks the problem of micro machine overload protection.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Fig. 1 to Fig. 4, a kind of multi-functional valve type shower nozzle of liquid release, including fixed cover 1 and overcoat 2, it is described
Overcoat 2 is threaded in inside fixed cover 1, and the bottom surface of fixed cover 1 is provided with the translot for fixation, is opened at the bottom centre of fixed cover 1
There is through hole E9, the outside of fixed cover 1 is provided with screw thread, for being connected with liquid release.Movable spray head 3 is equipped with inside the overcoat 2,
The vertical direction of movable spray head 3 is divided into upper, middle and lower segment, and the wherein diameter in stage casing is less than upper and lower two sections of diameters, and stage casing
On be provided with the through hole C7 of horizontal direction；Hypomere is placed in the through hole E9 of the bottom of fixed cover 1, and can be moved up and down in through hole E9,
The through hole D8 of vertical direction is provided with hypomere center, and through hole D8 communicates with through hole C7；The outer surface of upper of epimere is circumferentially with
Convex edge, spring 4 is provided between convex edge bottom and the inner bottom surface of fixed cover 1.Through hole A6, institute are provided with the upper surface center of overcoat 2
The external diameter for stating the epimere of movable spray head 3 is more than through hole A6 internal diameter.
For liquid release in off working state, the through hole A6 on overcoat 2 is by the pressure of spring 4 and by movable spray head 3
Upper end face closure, make the traced fluid of liquid release intracavitary non-leakage during transporting and going into the well.
And liquid release is in working condition, in the case where the piston of liquid release promotes, its intracavitary tracer hydraulic coupling P by
Cumulative height, intracavitary traced fluid promotes movable spray head 3, spring 4 axially downward by the through hole A6 on overcoat 2, on overcoat 2
Through hole A6 be opened, traced fluid is along the ring cavity 5 between the through hole A on overcoat 2, overcoat 2 and movable spray head 3, movable spray head 3
Cross through hole C7 and this path of longitudinal hole D8 discharged into testing well.After traced fluid release terminates, liquid release
Piston stop motion, intracavitary tracer hydraulic coupling P is gradually decrease to environmental pressure, in the presence of spring 4, along axis promotion activity
The upper surface of shower nozzle 3 is recovered to closed state, and now the through hole A6 on overcoat 2 is released by the upper end face closure of movable spray head 3, liquid
The remaining traced fluid put in device is closed, and non-leakage.
Through hole C7, the through hole being more than when the fouling solid particulate matter diameter that liquid release inner chamber is contained on movable spray head 3
D8 diameter and when causing its blocking, now intracavitary tracer hydraulic coupling P will continue to press on dynamic movable spray head 3, spring 4 axially downward
Mobile, when being overlapped at the thin neck in the stage casing of movable spray head 3 with the through hole E of fixed cover 1, the liquid release second for forming the shower nozzle is logical
Road, now the traced fluid of intracavitary piston promotion under, pass through the ring between the through hole A6 on overcoat 2, overcoat 2 and movable spray head 3
Continue to release into testing well in this path of second channel formed between the through hole E of chamber 5, the stage casing of movable spray head 3 and fixed cover 1
Put, through hole C7, the through hole D8 on movable spray head 3 block the release for not influenceing traced fluid.After traced fluid release terminates, liquid is released
The piston stop motion of device is put, intracavitary tracer hydraulic coupling P is gradually decrease to environmental pressure, in the presence of spring 4, pushed away along axis
The upper surface of dynamic movable spray head 3 is recovered to closed state, and the through hole A6 on overcoat 2 is by the upper end face closure of movable spray head 3, liquid
Remaining traced fluid in release is closed, and non-leakage.
The multi-functional valve type shower nozzle of this liquid release is a kind of and matching used radioactivity of oil field radioactivity logging device
Liquid release associated components, the traced fluid that liquid release is carried can be used for the test of tracer correlative flow, and this is multi-functional
Valve type shower nozzle also blocks up in addition to the basic function with control traced fluid injection form with anti-traced fluid seepage and preventing spray head passage
Function is filled in, is verified through field practice, obtains preferable application effect.
