Abstract
The utility model discloses a go-no-go pressure testing apparatus for a tube bundle of an air cooler. The apparatus comprises a strip-shaped guard plate, wherein two ends of the guard plate are connected with steel plate clamps via a locking device, a hollow square groove is movably connected to one side where the guard plate is close to one steel plate clamp, the square groove is equipped with an opening in one side where the square groove is far from the guard plate, and a water inlet pipe is connected to the square groove in a sealing manner. The testing apparatus can randomly carry out pressure testing on craters in dispute, thereby discovering defects existing in welding at early time and repairing the tube bundle with defects, and avoiding repair welding difficulty caused by that pressure testing after welding has problems.
Description
Technical field
The utility model relates to a kind of air cooler assembling pressure testing device, is particularly useful for the feel cold air cooler tube bundle go-on-go pressure testing device of middle tube bank of horizontal air cooler, compound type steamed.
Background technology
At present, horizontal air cooler and the compound type steamed middle tube bank weld bond that feels cold is more, has defective during welding, and after integral solder was finished, pressure testing went wrong and can cause the repair welding difficulty.
Summary of the invention
Problem to be solved in the utility model provides a kind of air cooler tube bundle go-on-go pressure testing device, to overcome the defective that when welding exists, avoid integral solder to finish after, the repair welding difficulty that pressure testing goes wrong and causes.
In order to address the above problem, the present invention by the following technical solutions:
A kind of air cooler tube bundle go-on-go pressure testing device, the backplate that comprises a block length strip, the two ends of described backplate are connected with the steel plate clip by locking device respectively, described backplate is connected with the square groove of inner hollow near a side of steel plate clip, one side of square groove has opening, its opening is arranged on square groove away from a side of backplate, is sealedly connected with water inlet pipe on the square groove.
Below be the utility model for further improvement of these options:
Backplate vertically arranges.
Further improve: described two steel plate clips up and down side by side and be oppositely arranged.
Further improve: the steel plate clip is Qian type structure.
Further improve: locking device is bolt, and an end of described bolt is fixedly connected with the steel plate clip, and the other end passes backplate and is connected with nut.
During pressure testing, with two up and down both sides that the steel plate clip blocks respectively the air cooler tube sheet up and down, then square groove is anchored on the air cooler tube sheet, and be positioned at square groove inside so that be welded on the end mouth of pipe of the steel pipe on the air cooler tube sheet, then put into rubber sheet gasket in the peripheral contact portion of air cooler tube sheet and square groove, be inserted in respectively the up and down two ends of backplate in two bolts on the steel plate clip and will fix with nut screwing clamping after the square groove fastening.
After fixedly finishing, water inlet pipe is linked to each other with pressuring pump, and behind the startup pressuring pump, water flows into square groove from pressuring pump by water inlet pipe, water in the square groove flows in the steel pipe, steel pipe other end sealing, pressuring pump pressure reached test pressure after, stop pressing and pressurize 30 minutes, check whether steel pipe and air cooler Tube-sheet Welding place have seepage, to there being the timely repair welding of weld bond that lacks weldering, the present invention adapts to the many air coolers of weld bond especially, can greatly increase work efficiency.
The utility model can be inspected the weld bond that has dispute by random samples, carries out pressure experiment, has defective when solving because of welding and finds early to reprocess, avoid integral solder to finish after, pressure testing goes wrong, and causes the repair welding difficulty.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Among the figure, 1-air cooler tube sheet; The 2-steel pipe; 3-steel plate clip; The 4-rubber sheet gasket; The 5-square groove; The 6-backplate; The 7-water inlet pipe; The 8-bolt; The 9-nut.
Embodiment
Embodiment, as shown in Figure 1, a kind of air cooler tube bundle go-on-go pressure testing device, the backplate 6 that comprises a block length strip, backplate 6 vertically arranges, and the two ends of described backplate 6 are connected with respectively the steel plate clip 3 of Qian type by locking device, and described backplate 6 is connected with the square groove 5 of inner hollow near a side of steel plate clip 3, one side of square groove 5 has opening, and its opening is arranged on square groove 5 away from a side of backplate 6.Be sealedly connected with water inlet pipe 7 on the square groove 5.
Described two steel plate clips 3 up and down side by side and be oppositely arranged;
Locking device comprises the bolt 8 of M12*60, and an end of described bolt 8 is fixedly connected with steel plate clip 3, and the other end passes backplate 6 and is connected with nut 9.
Take the horizontal air cooler as example, during pressure testing, with two up and down both sides that steel plate clip 3 blocks respectively air cooler tube sheet 1 up and down, then square groove 5 is anchored on the air cooler tube sheet 1, and be positioned at square groove 5 inside so that be welded on the end mouth of pipe of the steel pipe 2 on the air cooler tube sheet 1, then put into rubber sheet gasket 4 in air cooler tube sheet 1 and the peripheral contact portion of square groove 5, be inserted in respectively the up and down two ends of backplate 6 in two bolts on the steel plate clip 3 and will fix with the M12 nut screwing clamping after square groove 5 fastenings.
After fixedly finishing, water inlet pipe 7 is linked to each other with pressuring pump, and behind the startup pressuring pump, water flows into square grooves 5 from pressuring pump by water inlet pipe 7, water in the square groove 5 flows in the steel pipe 2, steel pipe 2 other ends sealings, pressuring pump pressure reached test pressure after, stop pressing and pressurize 30 minutes, check whether steel pipe 2 and air cooler tube sheet 1 weld have seepage, to there being the timely repair welding of weld bond that lacks weldering, the utility model adapts to the many air coolers of weld bond especially, can greatly increase work efficiency.
