When uses the ultrasonic probe to carry out liquid immersion process detection, the device has the characteristics of being high in operability, being stable in laminar flow effect, being simple, being exchangeable and the like.
Description
Technical field
The present invention relates to a kind of ultrasonic liquid nondestructive detector, particularly relate to a kind of ultrasound probe immersion coupling spreader.
Background technology
One of method that in immersion method, jet flow local immersion method is commonly used as ultrasonic reflectoscope, in detection process, can avoid direct contact with the shortcomings such as probe abrasion is too big, speed of detection is slower in method. And spreader is as the important component part in ultrasound wave immersion detection system, by hydraulic system, the couplant of voltage stabilizing is pumped into spreader. If after the couplant of voltage stabilizing is pressed directly into liquid-filled chamber, constantly probe can be impacted, cause probe to shake; If take couplant supply mode for axially supplying, but can not effectively reduce the turbulence pulsation speed that coupling is smooth; If the generation of extraordinary wave can be caused when jet flow post exists bubble, therefore, design spreader rational in infrastructure to form stable fluid column between probe and measured piece and get rid of air between the two, make the ultrasound wave sound intensity strengthen in the absorbance of liquid-solid interface, and the flow regime in coupling flow field can be controlled further and improve fluid column laminar flow fluctuation velocity.
Summary of the invention
It is an object of the invention to provide a kind of ultrasound probe immersion coupling spreader, the present invention devises a kind of spreader being more easy to installation, dismounting, replacing probe, and ensures the speed of certain injection couplant and the laminar flow pattern of water column; Couplant, behind annular water-filling room, can reach laminar flow effect stability through three layers hole sizer, and device installs simple easily replacing different model probe.
It is an object of the invention to be achieved through the following technical solutions:
A kind of ultrasound probe immersion coupling spreader, described spreader includes end cap, probe cutting ferrule, body, nozzle, liquid injecting mouth; End cap is bolted on lathe probe holder, is arranged on end cap by body, probe card in probe cutting ferrule, is positioned over upper end of nozzle, is installed along with on body with nozzle, liquid injecting mouth is finally arranged on the side of body; Now the hydraulic system of couplant is connected on liquid injecting mouth, couplant can be injected, and proceed by the flaw detection that testee is carried out ultrasound wave immersion mode.
Described a kind of ultrasound probe immersion coupling spreader, described end cap, probe cutting ferrule, body, nozzle are all symmetrical with centrage.
Described a kind of ultrasound probe immersion coupling spreader, described nozzle and body, body and end cap and liquid injecting mouth all adopt with body threadeds.
Described a kind of ultrasound probe immersion coupling spreader, on described nozzle, part annular screen has three layers hole sizer structure, and the couplant in annular water-filling room enters nozzle interior with layer flow mode.
Described a kind of ultrasound probe immersion coupling spreader, described probe cutting ferrule is fixed by body and nozzle, and probe card set is for difform probe, change the interior shape of probe cutting ferrule, closing with probe matching form, probe takes interference fit to fix with probe cutting ferrule, probe cutting ferrule with body.
Described a kind of ultrasound probe immersion coupling spreader, described probe card cover material selects nitrile rubber.
Advantages of the present invention and effect be:
1. the present invention is directed to the spreader structure of prior art, devise a kind of spreader being more easy to installation, dismounting, replacing probe, and ensure the speed of certain injection couplant and the laminar flow pattern of water column.
2. spreader of the present invention is when using ultrasound probe to carry out the detection of immersion method, has couplant behind annular water-filling room, can reach laminar flow effect stability through three layers hole sizer, and device is installed and simply easily changed the advantages such as different model probe.
Accompanying drawing explanation
Fig. 1 is spreader sectional arrangement drawing;
Fig. 2 is the structure chart of nozzle in spreader.
Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is described in detail.
In figure: end cap 1, probe cutting ferrule 2, body 3, nozzle 4, liquid injecting mouth 5, probe 6, liquid injection port 7, mouth spray 8, annular screen 9, annular water-filling room 10, centrage 11.
End cap 1 is first bolted on lathe probe holder by spreader of the present invention, body 3 is arranged on end cap 1, probe 6 is stuck in probe cutting ferrule 2, is positioned over nozzle 4 upper end, it is installed along with on body 3 with nozzle 4, finally liquid injecting mouth 5 is arranged on the side of body 3. Now the hydraulic system of couplant is connected on liquid injecting mouth 5, couplant can be injected. Couplant after injection enters annular water-filling room 10, and hydraulic system inlet pressure, because of the small volume of device own, is improved in the annular water-filling room 10 that nozzle 4 and body 3 are formed, and couplant can be full of annular water-filling room 10 by a liquid injecting mouth. Couplant in annular water-filling room 10 is entered inside nozzle 4 by annular screen 9, on nozzle 4, part annular screen 9 has three layers hole sizer structure, can ensure that the couplant in annular water-filling room 10 enters nozzle interior with layer flow mode, be directly ejected on measured piece through mouth spray 8 through pressure.
Embodiment one: Fig. 1 is the sectional arrangement drawing of this spreader. End cap 1 is first bolted on lathe probe holder by spreader, is arranged on end cap by body 3, probe 6 is stuck in probe cutting ferrule 2, is positioned over nozzle 4 upper end, is installed along with on body with nozzle 4, liquid injecting mouth 5 is finally arranged on the side of body.
Embodiment two: the hydraulic system of couplant is connected on liquid injecting mouth 5, couplant can be injected.
