Abstract
The utility model relates to a nondestructive inspection technique for a dissimilar metal weld and particularly discloses a coupling agent storage device for ultrasonic automatic inspection of a pipe weld. The coupling agent storage device comprises a container. A circular hole is arranged at the bottom of the container. A circular-ring clamping plate is fixedly arranged on the edge of the circular hole. The cross section of the circular-ring clamping plate is T-shaped. A sealing ring is arranged on the internal side of the clamping plate. An annular groove is arranged on the side wall of the clamping plate. By designing the sealing ring, the coupling agent can smoothly flow into the container, is ensured to not flow out, can be prevented from flowing onto the top cover of the pressure container and simultaneously can be effectively collected; and by adopting two kinds of designs, i.e. a direct sheathing type and a clamping ring type, the device is convenient to install and the applicability is strong.
Description
Technical field
The utility model belongs to the weld seam Dynamic Non-Destruction Measurement, is specifically related to a kind of couplant storage device.
Background technology
Nuclear plant pressure vessels top cover instrument measurement pipe is used for neutron flux in the gaging pressure container, be distributed with 8 instrument measurement pipes on each top cover, instrument measurement pipe dissimilar metal welding line belongs to a circuit system non-destructive test, because be easy to generate defectives such as bubble, crackle in the weld seam of dissimilar metal welding back, poor weld is easy to generate fracture at fault location.The radioactive cooling system conditioner of one loop band is leaked, thereby serious safety misadventure will take place, therefore must regularly check this weld seam.In checking process, must give that probe provide lasting couplant in the checking tool, and couplant can not be emitted on directly on the top cover, therefore just need special-purpose couplant storage device of research and development that couplant in the checking process is collected, recycle, finish inspection smoothly.
Because the radioactive dosage on the top cover is bigger, should not be for a long time under environment like this mounting tools, therefore, the installation of this coupling agent device must be fast and must the employing clamping mode.
Other unit does not have mature technology and special-purpose checking tool to this position welding inspection both at home and abroad at present, the also couplant storage device of this position special use not, so can't use for reference forefathers' design experiences, this isolated plant belongs to water storage use when for the first time this position being checked.
Summary of the invention
The purpose of this utility model is to provide a kind of couplant in can butt tube welding line ultrasonic automatic inspection process effectively to collect, and easy for installation fast, the adapter welding line ultrasonic automatic inspection couplant storage device of favorable sealing property.
The technical solution of the utility model:
A kind of adapter welding line ultrasonic automatic inspection couplant storage device, it comprises container, and container bottom is provided with circular hole, and described circular hole edge is fixed with the annular arrangement clamp, and its cross section is a T shape, and described clamp inboard is provided with seal ring, and sidewall is provided with the groove of annular.
In above-mentioned adapter welding line ultrasonic automatic inspection couplant storage device: the ring inboard of described seal ring is provided with the lip limit of protrusion, the inboard one-tenth of the seal ring face of cylinder of below, lip limit, and the seal ring upper surface is bevelled drainage face, the inboard of drainage face is higher than the outside.
In above-mentioned adapter welding line ultrasonic automatic inspection couplant storage device: the refluence face that is provided with protrusion outside the described seal ring ring.
In above-mentioned adapter welding line ultrasonic automatic inspection couplant storage device: described container and seal ring can be processed as two parts, and contacted part is provided with hinge and clamp.
In above-mentioned adapter welding line ultrasonic automatic inspection couplant storage device: described container bottom also is provided with water outlet.
Advantage of the present utility model is: the design by seal ring makes couplant flow in the container smoothly, and does not outflow, and prevents to flow on the pressure vessels top cover, can couplant effectively be collected simultaneously; Adopt two kinds of designs of straight shell type and snap ring-type, easy for installation, applicability is strong.

Fig. 2 b is the birds-eye view of Fig. 2 a;
Fig. 3 is that seal ring cooperates scheme drawing with measuring tube;
Among the figure: 1. container; 2. seal ring; 3. clamp; 4. circular hole; 5. clamp; 6. hinge; 7. water outlet; 8. lip limit; 9. drainage face; 10. refluence face; 11. groove; 12. measuring tube; 13. the face of cylinder.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail:
Be illustrated in figure 1 as the structural representation of the seal ring 2 that adopts in the utility model, be processed into the structure on the lip limit 8 of protrusion in the ring inboard of seal ring 2, when seal ring was in running order, lip limit 8 smallest circle ring diameters were less than instrument measurement pipe 12 work external diameters.The below on lip limit 8 is faces of cylinder 13, because the protrusion on lip limit 8, feasible installing and measuring managed 12 o'clock, turned on the lip limit 8, be close on the outer wall of measuring tube 12, and the face of cylinder 13 formed certain intervals with measuring tube 12 outer walls.
As shown in Figure 1, the refluence face 10 of protrusion is processed in the ring outer of seal ring 2, refluence face 10 lower sidewalls are processed with the groove 11 of annular, seal ring 2 upper surfaces between lip limit 8 and refluence face 10 are drainage faces 9, because lip limit 8 level attitudes are higher than refluence face 10, therefore drainage face 9 is inboard high, and the outside is low.
Shown in Fig. 2 a and Fig. 2 b, the bottom of container 1 has a circular hole 4, the fixing welding one circle clamp 3 at the edge of circular hole 4, clamp 3 cross sections become T shape, seal ring 2 is installed in clamp 3 inboards, and the groove 11 of seal ring 2 adopts interference fit with clamp 3, and the groove 11 on the seal ring 2 blocks clamp 3, refluence face 10 is stuck in clamp 3 upper surfaces, thereby makes that seal ring 2 is fixing.Can leave the mouth of a river 7 in container 1 bottom, make couplant from water outlet 7 flow containers.
Because the vertically arranged a bit closed conduct of nuclear station is a loop, no end-blown, can't realize straight shell type installation, therefore present embodiment adopts snap ring-type to install, shown in Fig. 2 a and Fig. 2 b, container 1 is processed into two parts, every part is left the mouth of a river 7 respectively, local hinge 6 and the clamp 5 installed in two parts joint, this moment, seal ring 2 was processed into identical two parts.By hinge 6 and clamp 5 container 1 is connected as a single entity during use, two parts are separately embraced measuring tube, and two parts seal ring 2 closely is attached to the outer wall of measuring tube respectively, utilize hinge 6 and clamp 5 to step up again.
As Fig. 2 a, Fig. 2 b and shown in Figure 3, when measuring tube 12 passes circular hole 4, seal ring 2 is enclosed on measuring tube 12 outer walls, because protrude on lip limit 8, seal ring 2 is to adopt flexible material, makes lip limit 8 be close to the outer wall of measuring tube 12, forms interference fit.When couplant when measuring tube 12 flows down, be subjected to stopping of lip limit 8, outwards flow out along drainage face 9, the face of cylinder 13 does not contact with measuring tube 12 outer wall surface, because the protrusion of refluence face 10 makes couplant flow in the container.
