Abstract
The utility model is a kind of water logging voussoir for HDPE pipe-line system non-destructive testing.Its specific constructive form mainly includes five parts: (1) couplant conveys connector；(2) abrasionproof is followed closely；(3) voussoir main body；(4) elastic abrasionproof water skirt；(5) high-frequency ultrasonic is popped one's head in.Elastic abrasionproof water skirt (4) improves the compactness with HDPE workpiece to the utility model in use, reduces air error.The water cavity of couplant can be effectively formed between voussoir main body (3), elastic abrasionproof water skirt (4) and high-frequency ultrasonic probe (5), and high-frequency ultrasonic probe threaded hole can exclude bubble in water cavity in time, the accuracy rate of HDPE pipe-line system non-destructive testing result can effectively be promoted, it is ensured that pipe-line system it is safe and reliable.
Description
Technical field
The utility model relates to polyethylene pipe system Ultrasonic Nondestructive technical fields.
Background technique
High density polyethylene (HDPE) (HDPE) tubing have it is corrosion-resistant, hydraulic characteristic(s) is good, anti-seismic performance is excellent, long service life and
Many advantages, such as radiation resistance, is widely used in municipal water supply, fuel gas transmission, urban pipe network transformation and petrochemical industry etc. in recent years
Field.And due to it is domestic and international a large number of studies show that HDPE tubing to be very suitable to replacing nuclear power station circulating water cooling system existing
Carbon steel pipe and line plastic-steel tube, to solve the problems, such as the seawater corrosion of carbon steel pipe and line plastic-steel tube.
The connection of HDPE pipeline generallys use heat-melting butt-joint and connects two ways with electric smelting.It is higher for security requirement
Fuel gas transmission industry once required to ensure pipe-line system without inside using Ultrasonic Nondestructive technology to HDPE pipe-line system and connect
Connector defect guarantees safety.For the nuclear power HDPE pipeline field that the country has just emerged, then HDPE pipe-line system is forced
Property require implement Ultrasonic Nondestructive technology.
Although Ultrasonic Nondestructive technology is highly developed in metal material field, for the super of HDPE pipe-line system
Sound wave non-destructive testing still has technological difficulties, mainly has (1) ultrasonic wave to decay in HDPE material larger, echo is weak；(2) surpass
The velocity of wave of sound wave speed in the voussoir of traditional organic glass (polymethyl methacrylate) material and HDPE pipe-line system is different
It causes, ultrasonic signal is unable to reach the demand of detection.Therefore, in order to realize Ultrasonic Nondestructive technology in HDPE pipe-line system
Application, it is necessary to a kind of novel voussoir is provided.
Utility model content
1. to solve the above problems, the utility model provides a kind of water logging wedge for HDPE pipe-line system non-destructive testing
Block.
2. the technical solution of the utility model is:
A kind of water logging voussoir for HDPE pipe-line system non-destructive testing mainly includes that (1) couplant conveys connector；(2)
Abrasionproof nail；(3) voussoir main body；(4) elastic abrasionproof water skirt；(5) high-frequency ultrasonic is popped one's head in.It is characterized in that one is passed through micro- injection molding
Ultra-high frequency ultrasonic wave probe (5), elastic abrasionproof water skirt (4), abrasionproof nail are mounted on integrally formed voussoir main body (3)
(2) and couplant conveys connector (1).
The advantage of this programme and the prior art is: the voussoir main body of 1. micro- integrally formed PE100RC materials will not be right
The ultrasound examination of HDPE workpiece generates interference；2. elastic abrasionproof water skirt can increase the compactness with HDPE workpiece, and will not damage
Hurt workpiece；3. couplant can be effectively formed between voussoir main body (3), elastic abrasionproof water skirt (4) and high-frequency ultrasonic probe (5)
Water cavity, and corresponding water vapo(u)r bubble can be removed, substantially effectively promote the accuracy rate of HDPE pipe-line system non-destructive testing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the left view of the utility model.
Specific embodiment
1. high-frequency ultrasonic probe (5) is installed in the voussoir main body (3) of integrated injection molding.Then voussoir is put into HDPE
Couplant is injected to voussoir (3) by couplant conveying connector (1) in the surface of workpiece, when for the test of HDPE workpiece, choosing
It is deionized water with couplant, after water enters voussoir main body (3), is visited in voussoir main body (3), abrasionproof water skirt (4) and high frequency ultrasound
A water cavity, the couplant when deionized water in water cavity is Ultrasonic Nondestructive are generated between head (5).
2. depth of focus 20mm-30mm is adjusted, then by the Scanning speed 120mm/s of setting with linear scanning mode
Scanning detection is carried out to HDPE workpiece.
3. above-mentioned technical proposal is a kind of embodiment of the utility model, for those skilled in the art
Speech, on the basis of the utility model discloses application method and principle, it is easy to various types of improvement or deformation are made, and
It is not limited only to structure described in the above-mentioned specific embodiment of the utility model, therefore previously described mode is only preferably,
And not restrictive meaning.
