Description
Technical field
The utility model relates to defect-detecting equipment technical field more particularly to a kind of vortex combined flaw detection secrets of novel ultrasonic-
Envelope guiding sheath.
Background technique
Nuclear steam generator has the characteristics that specification is small, length is big with pipe, during atual detection by straight tube straight line
Degree, equipment swivel head leakproofness and couple state etc. influence, it may appear that detection system is unstable, influences testing result
Accuracy the problem of.Before the detection of straight tube, straight pipe sheath need to be installed, current guide sleeve is only to pass through for straight tube
Tubular structure, function is insufficient, and leakproofness is poor, couplant pressure change often occurs and medium leakage causes interference with influence
The case where testing result accuracy.In addition, guiding sheath it is easily-deformable in use, damaged, can damage equipment especially pair
Straight tube tube surfaces cause to scratch, damage, and it without hydraulic pressure function is adjusted, detection coupling performance is poor.
Utility model content
The utility model provides a kind of vortex combined defectoscope sealing guiding sheath of novel ultrasonic-, treats the straight of flaw detection
Pipe is protected, and is avoided that the damaging of straight tube, scuffing problem, while straight tube size and shape being avoided to generate variation, is straight tube
Stablize, accurate detection provides safeguard.
In order to reach the purpose, the utility model adopts the following technical solution:
A kind of vortex combined defectoscope sealing guiding sheath of novel ultrasonic-, it is characterised in that: including ontology, the ontology
On be provided with through-hole and guide part and interconnecting piece along through-hole extending direction setting, the interconnecting piece are equipped with around institute
The sealing ring of interconnecting piece is stated, the ontology is equipped with the regulator hole through the ontology.
As a preference, the guide part and the interconnecting piece are cylindrical structure, the diameter of the guide part is less than
The diameter of the interconnecting piece, the two constitute step structure.
As a preference, the regulator hole is parallel to the through-hole setting, the quantity of the regulator hole is four and edge
The through-hole is circumferentially uniformly arranged.
As a preference, the interconnecting piece is equipped with the groove of annular, the sealing ring is embedding in the groove.
As a preference, it is circular rubber seal that the sealing ring, which is section,.
As a preference, the through-hole both ends are equipped with annular chamfer.
As a preference, the ontology is made of nylon material.
To sum up, compared with the prior art, the advantages of the utility model are: the copper sleeve internal diameter of interconnecting piece and defect-detecting equipment
In mating connection, straight tube passes through guiding sheath, avoids damaging between straight tube and defect-detecting equipment, scuffing problem, avoids simultaneously
Straight tube size and shape generate variation, provide safeguard for the stabilization of straight tube, accurate detection；Rubber seal ensure that defect-detecting equipment
In the leakproofness of couplant the hydraulic pressure of couplant is adjusted, to fill while by regulator hole balancing equipment swivel head hydraulic pressure
Divide the surface coupling performance for reaching tubing.

Specific embodiment
The utility model is described in further detail for middle embodiment with reference to the accompanying drawing.
A kind of vortex combined defectoscope sealing guiding sheath of novel ultrasonic-as depicted in figs. 1 and 2, which includes this
Body 1 is provided with through-hole 11 and guide part 12 and interconnecting piece 13 along the setting of 11 extending direction of through-hole, guide part 12 on ontology 1
It is located remotely from probe and couplant side relative to interconnecting piece 13, guide part 12 and interconnecting piece 13 can be integrated injection molding.
Guide part 12 and interconnecting piece 13 are cylindrical structure, and the diameter of guide part 12 is less than the diameter of interconnecting piece 13, and the two constitutes step
Structure.13 outer diameter of interconnecting piece is matched with the copper sleeve internal diameter of defect-detecting equipment, is fixedly connected to sheath, 12 internal diameter of guide part
Consistent with straight tube outer diameter to be detected, guide part 12, to guarantee the linearity of its movement, avoids to be detected to being intuitively oriented to
Straight tube damages during access device with the collision of equipment other structures.Interconnecting piece 13 is equipped with around interconnecting piece 13
Sealing ring 2, ontology 1 are equipped with the regulator hole 14 through ontology 1.
Regulator hole 14 is parallel to the setting of through-hole 11, and the quantity of regulator hole 14 is four and is circumferentially uniformly arranged along through-hole 11.
Interconnecting piece 13 is equipped with the groove 15 of annular, and sealing ring 2 is in groove 15.Sealing ring 2 is that section is circular rubber seal
Circle 2.Rubber seal 2 avoids the couplant such as deionized water of side from revealing, meanwhile, it is rotated by 14 balancing equipment of regulator hole
Head hydraulic pressure, adjusts the hydraulic pressure of couplant, to sufficiently achieve the surface coupling performance of tubing, prevents the generation of interference water vapor bubbles,
Guarantee going on smoothly for detection.
11 both ends of through-hole are equipped with annular chamfer 111, in order to test tube to be checked entrance.Ontology 1 is made of nylon material, material
In do not include the harmful elements such as Cl-, F-, S, Pb, while being not easy expansion and contraction distortion.
