Abstract
The utility model discloses a double-layered water level water tank for steel pipe ultrasonic flaw detection, which comprises a tank body; two groups of ultrasonic probes are arranged in the tank body; the water tank is characterized in that layered hard thick plates (7) are arranged in the tank body; the layered hard thick plates (7) are arranged at the positions of the ultrasonic probes; the layered hard thick plates (7) are provided with two parallel clinging block chutes (5); two groups of clinging blocks (1, 2, 3 and 4) are arranged between the two parallel clinging block chutes (5); the clinging blocks (1 and 2) are in a group, and the clinging blocks (3 and 4) are in the other group; probe calibers (6) are respectively arranged between the clinging blocks (1 and 2) and the clinging blocks (3 and 4), and the two groups of probe calibers (6) cling to the two groups of ultrasonic probes; consequently, the water tank forms a dynamic-static double-layered water level so as to ensure that the water flow between the probes and a steel pipe is stable, the pressure of all parts is close, and the ultrasonic attenuation quantity is also close; and simultaneously, water spray, bubbles, impurities and other interference are prevented, and such misstatement is reduced and even avoided.
Description
Technical field:
The utility model relates to the steel tube flaw detection technical field, is a kind of double-deck water level water tank that is used for steel tube supersonic flaw detecting specifically.
Background technology:
At present steel tube flaw detection is when utilizing the water coupling to carry out UT (Ultrasonic Testing), probe with visited between the steel pipe and can cause flaw detection to report by mistake because there being impurity such as spray, bubble, hammer scale; In addition, probe is with different by coupling water flow velocity between the spy steel pipe, and the each point pressure transient also can be different to hyperacoustic attenuation degree, thereby cause the instability of flaw detection sensitivity, may produce the result of detection of omission or tightened inspection thus.For steel pipe rotation advance, water tank (including ultrasonic probe) trailing type ultrasonic test equipment, no matter water tank inlet is in which position, all can't avoid two groups of symmetry probes and quilt to visit the influence to flaw detection wrong report and flaw detection sensitivity difference such as the spray of coupling water between steel pipe, bubble, flow rate of water flow, usually all be to reduce wrong report and balance flaw detection sensitivity by changing water inlet position and water inlet flow rate of water flow, but because the restriction of water tank size and flow rate of water flow can not produce a desired effect mostly.
Summary of the invention:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of double-deck water level water tank that is used for steel tube supersonic flaw detecting is provided, mainly solve the existing water tank that is used for UT (Ultrasonic Testing) and can't avoid two groups of symmetry probes and problems such as wrong report and flaw detection sensitivity difference flaw detection be occurred by the spray of coupling water between the spy steel pipe, bubble, flow rate of water flow etc.
In order to achieve the above object, the utility model is achieved in that a kind of double-deck water level water tank that is used for steel tube supersonic flaw detecting, it comprises casing, two groups of ultrasonic probes are arranged in the casing, its special character is to establish the hard slab of layering in casing, the hard slab of layering is positioned at the appropriate location of ultrasonic probe, on the hard slab of layering, establish two parallel piece chutes that are adjacent to, establishing first group between the piece chute two parallel being adjacent to is adjacent to piece and second group and is adjacent to piece, first group be adjacent between the piece and second group be adjacent to and establish bore probe between the piece respectively, two groups of bore probes are close to two groups of ultrasonic probes.
Compared with the prior art a kind of double-deck water level water tank that is used for steel tube supersonic flaw detecting described in the utility model has following good effect: adopt the hard slab of layering, and place it in the appropriate location of probe on the height, the main frame water tank highly in position is divided into two parts up and down according to probe, water inlet is at water tank bottom, in water tank, form two states water, the lower part flow velocity is very fast, bubble, spray, contain impurity such as hammer scale more be dynamic water, flowing into water tank upper around the water level decker divides flow velocity slow, contamination precipitation, no bubble, what spray etc. disturbed is Static Water; Thereby guaranteed that flow is stable between probe and steel pipe, pressure is close everywhere, and is close to the ultrasonic attenuation amount; Also avoid simultaneously the interference of spray, bubble, impurity etc. to produce, reduced even stopped this type of wrong report, improved the flaw detection precision of steel pipe.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe a kind of double-deck water level water tank that is used for steel tube supersonic flaw detecting of the utility model in detail.
Embodiment 1, referring to Fig. 1, be processed into tank box, and two groups of ultrasonic probes are installed within it, according to the water tank internal diameter size, adopt the above thick offset plate of monoblock of thickness 3mm, also can adopt other materials, make the hard slab 7 of layering, hard slab 7 sizes of layering are slightly larger than the water tank internal diameter, on the hard slab 7 of layering, offer two parallel piece chutes 5 that are adjacent to, install two groups two parallel being adjacent between the piece chute 5 and be adjacent to piece 1,2,3,4, be adjacent to piece 1,2 is one group, be adjacent to piece 3,4 is one group, be adjacent to piece 1, between 2 and be adjacent to piece 3, offer bore probe 6 between 4 respectively, the hard slab 7 of layering is installed in the appropriate location of ultrasonic probe height, two groups of bore probes 6 of example are close to two groups of ultrasonic probes.
A kind of double-deck water level water tank that is used for steel tube supersonic flaw detecting described in the utility model, during use, because the hard slab of layering is placed on the appropriate location on the probe height, its size is slightly larger than the water tank internal diameter, it is fixed on the tank inner wall and coupling water can flow out, the hard slab secure fit of layering prevents that current from flowing into the probe top from here and forming labile factor, thereby makes water tank form the double-deck water level of sound on probe around the probe.Thereby guaranteed that flow is stable between probe and steel pipe, pressure is close everywhere, and is close to the ultrasonic attenuation amount; Also avoided simultaneously the interference of spray, bubble, impurity etc. to produce, reduced even stopped this type of wrong report.
