Description
Technical field
The utility model relates to a kind of ultrasound wave angle probe, and concrete is a kind of signal connector ultrasound wave angle probe up.
Background technology
The ultrasound wave angle probe is mainly used in the ultrasonic transverse wave flaw detection, and angle probe is made up of housing, skewback, piezoelectric chip, damping block.With the refraction angle tangent value of K value nominal probe, the location Calculation of defective is more convenient.The acoustic beam of angle probe and detecting head surface tilt, and therefore can be used for detecting the zone that has angle between the direction of position that straight acoustic beam can't arrive or defective and the detection faces.
The welding joint of metal current pipeline and pressure vessel all is as detection method commonly used with ultrasound examination, and most important detection part is exactly the ultrasound wave angle probe, but our usual being seen ultrasound wave angle probe signal connector backwards, if and there is the structural member influence welding joint both sides in testing process, then may not reach the minimum displacement (1.25P that requires probe among the JB/T4730-2005 " bearing device Non-Destructive Testing ", P=2Ttan β, β is the refraction angle of probe, T is the thickness of detected workpiece), can cause the omission of detected weld defective like this, influence the monitored area.
The utility model content
For addressing the above problem, the utility model provides a kind of ultrasound wave angle probe, eliminates structural member to the mobile influence of popping one's head in, and improves the reliability and the usability of probe.
The technical solution adopted in the utility model is as follows:
The utility model comprises housing, skewback, piezoelectric chip and damping block, described skewback is arranged in the housing, described piezoelectric chip is fixed on the inclined-plane of skewback, described damping block is positioned at piezoelectric chip top, be filled with acoustic absorbant between described housing and the skewback, be provided with vertical signal connector in described case top, be connected by cable between described signal connector and the piezoelectric chip.
The oblique angle α of described skewback is 20 ~ 60 °.
Good effect of the present utility model is as follows: the utility model is as a kind of ultrasound wave angle probe, the not enough shortcoming in monitored area when influenced by structural member at existing probe, by being provided with vertical signal connector stating case top, can eliminate structural member to the mobile influence of popping one's head in, increase the effective displacement of probe, and then improved the reliability and the usability of probe.The utility model is simple in structure, be easy to processing, and is easy to use, is used for the ultrasound examination of the welding joint of metallic conduit and pressure vessel.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
In the accompanying drawings: 1 housing, 2 skewbacks, 3 piezoelectric chips, 4 damping blocks, 5 signal connectors, 6 acoustic absorbants, 7 cables.
Embodiment
As shown in Figure 1, the utility model comprises housing 1, skewback 2, piezoelectric chip 3 and damping block 4, described skewback 2 is arranged in the housing 1, described piezoelectric chip 3 is fixed on the inclined-plane of skewback 2, described damping block 4 is positioned at piezoelectric chip 3 tops, be filled with acoustic absorbant 6 between described housing 1 and the skewback 2, it is characterized in that being provided with vertical signal connector 5, be connected by cable 7 between described signal connector 5 and the piezoelectric chip 3 at described housing 1 top.
The effect of skewback 2 is the conversions that realize wave mode, and the oblique angle α of skewback 2 is 30 °, and the acoustic absorbant in the housing 1 is used for absorbing the noise of dispersing around piezoelectric chip 3 back sides and the skewback 2; Housing 1 plays effects such as support, protection, electromagnetic screen; Electric signal interface 5 is a plug, is connected on the instrument by probe wire, and then finishes monitoring.
The utility model changes the electric signal interface 5 with probe of probe wire on the basis of common ultrasound wave angle probe, and signal connector 5 is designed to housing 1 top, has so just increased effective displacement of the present utility model.
The material of described damping block 4 is epoxy resin and tungsten powder, and the material of described skewback 2 is an organic glass.
