Abstract
A transverse wave water-jet probe comprises a press cover (7), a housing (5) provided with a water outlet hole (10), a choke plug (12) provided with a pulling eye (11) and an organic shim block (9) positioned in the housing cavity (14), wherein periphery of the lower edge of the organic shim block (9) is fixed with the housing (5) by sealing gum (13); a wire (8) is connected on the organic shim block (9); the wire (8) is extracted from the pulling eye (11) of the choke plug (12); the press cover (7) is provided with a water inlet pipe (2); both the choke plug (12) and the press cover (7) are connected in a fixed manner with the housing (5); a regulator nut (3) and a locking nut (4) are screwed-in on the external circle of the lower end of the housing (5), and the locking nut (4) is positioned above the regulator nut (3). Taking advantage of transverse waves, the utility model helps convenient detection of defects and scars in parallel with longitudinal waves on work pieces during fault detection, therefore can prevent inspection omissions and further improve the inspection accuracy.
Description
Technical field
The utility model relates to a kind of failure detector, and particularly a kind of shear wave water spray probe is mainly used in defective or the scar of surveying workpiece inside.
Background technology
Water spray probe commonly used in the market is longitudinal wave probe, and there is following deficiency in this probe: be difficult to be found when the wound of workpiece is parallel with compressional wave, thereby cause detecting error.
Summary of the invention
The purpose of this utility model is exactly to overcome the deficiencies in the prior art to provide a kind of accuracy of detection high shear wave water spray probe.
The technical scheme that realizes above-mentioned purpose is: a kind of shear wave water spray probe, comprise gland, take out of the water hole housing, the band fairlead plug and place the endoceliac organic voussoir of shell, fix by fluid sealant and housing around organic voussoir lower edge, be connected with lead on organic voussoir, this lead is drawn from the fairlead of plug, has water inlet pipe on the gland, plug is all fixedlyed connected with housing with gland, be connected with setting nut and set nut on the cylindrical of housing lower end, and set nut is positioned at the setting nut top.
After adopting technique scheme, angle by organic voussoir changes, the size of scalable incident angle, incident angle is changed between 10 °～70 °,, incident angle on organic voussoir is sent out a little remained on 0.5～4mm from the distance that is detected surface of the work by the rotation of setting nut on housing, thereby generation shear wave, can detect the scar parallel in the workpiece easily, avoid omission, improve accuracy of detection with compressional wave.In addition, the utility model can 360 ° of rotations, have further improved sensing range.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Shown in Fig. 1～4, a kind of shear wave water spray probe, comprise gland 7, take out of water hole 10 housing 5, band fairlead 11 plug 12 and place organic voussoir 9 in the housing chamber 14, fixing with housing 5 around organic voussoir 9 lower edges by fluid sealant 13, be connected with lead 8 on organic voussoir 9, this lead 8 is drawn from the fairlead 11 of plug 12, has water inlet pipe 2 on the gland 7, plug 12 is all fixedlyed connected with housing 5 with gland 7, be connected with setting nut 3 and set nut 4 on the cylindrical of housing 5 lower ends, and set nut 4 is positioned at setting nut 3 tops.Water inlet pipe 2 is threaded with gland 7, and plug 12 also is threaded with housing 5, and gland 7 is fixedlyed connected with housing 5 by screw 6.
As shown in Figure 1, 2, be set with waterproof jacket 1 on the plug 12, and the center pit that allows waterproof jacket 1 pass be set at gland 7.Adopt this structure can prevent that sealing enters in the chamber 14 of housing 5 from the fairlead 11 of plug 12.
The fluid sealant of fixing with housing around organic voussoir 9 13 can adopt epoxy resin.Good seal performance not only, and fixing reliable, can avoid organic voussoir 9 to come off, can prevent that again sealing enters in the chamber 14 from the lower end of housing 5.
As shown in Figure 5, principle of work of the present utility model is as follows: when the transmitting probe ultrasonic waves transmitted ran into defective 15, most of ultrasound wave was reflected to the workpiece bottom, and the ultrasound wave of secondary reflection is received the probe reception again.Incident angle α is between 10 °～70 °, the variation of incident angle α can change by organic voussoir 9 angles to be regulated, and the distance of the incident angle launching site and the surface of the work of being detected a flaw must guarantee at 0.5～4mm, this distance can be regulated by the setting nut on the probing shell 3, after determining good distance, with set nut 4 lockings.
