Abstract

The utility model relates to the technical field of a sealing tool for a hydraulic test on a heat exchanger, and provides a packing box for the hydraulic test on the floating tube sheet end of a floating head type heat exchanger. The packing box is characterized in that a flange of the packing box body is connected with a heat exchanger housing, and a heat exchange pipe 4 is arranged in the heat exchanger housing 3 and a cylindrical shell section 8 of the box body; and a ring-shaped groove is formed on the inner surface where the cylindrical shell section 8 of the box body is in contact with a floating tube sheet 14, an asbestos packing 9 and a tapered snap ring 10 are arranged in the space between the floating tube sheet 14 and the ring-shaped groove, and the inner end of a cylindrical shell section 13 of a gland bush is closely propped against the tapered snap ring 10. The contact surface of the tapered snap ring 10 and the cylindrical shell section 13 of the gland bush adopts an inclined plane of 45 degrees. The inner end surface of the cylindrical shell 8 section of the packing box body and the asbestos packing 9 are processed into a bevel edge of 45 degrees. When a leak detection hydraulic test on the tube union is performed through the floating head type heat exchanger, the utility model can form a closed cavity through a fixed tube sheet, the housing, the heat exchange pipe and the floating tube sheet effectively, so as to check the connection and leakage situations of each tube union quickly.

Description

Movable tube sheets heat exchanger floating tubesheet end hydraulic testing stuffing box

Technical field

The utility model relates to heat interchanger hydraulic testing sealing frock technical field, particularly movable tube sheets heat exchanger floating tubesheet end hydraulic testing stuffing box.

Background technology

The pipe seal performance of wanting heat exchanging tube and tube plate to connect after the movable tube sheets heat exchanger manufacturing finishes is tested, because floating tubesheet is in quick condition in heat exchanger shell inside, want during the hydraulic testing the sealing of the gap between floating tubesheet and the housing, just need to adopt a cover frock.Generally speaking, the hydraulic testing is that the floating head assembly, hook circle, gasket seal and the coupling bolt that utilize movable tube sheets heat exchanger itself intrinsic seal the floating tubesheet outer face, and then a tube bank holds the own bobbin carriage parts of stationary tubesheet outer face and heat interchanger to be connected in addition, bobbin carriage, tube sheet, heat exchanger tube, floating head assembly etc. form the hydraulic testing cavity of sealings like this, the pipe adapter leak case that this method can only be connected with tube sheet from two tube sheet inner surface inspection heat exchanger tubes.Because the heat exchanger tube tube bank is overlaped by many heat exchanger tubes, in case certain pipe adapter is revealed, be difficult to judge that fast that root heat exchanger tube joint has problem that hydraulic test efficiency is low.

Summary of the invention

Hang down and can not accurately judge fast the deficiency of pipe adapter leak position in order to overcome general floating end tube sheet hydraulic test method efficient, the utility model provides a kind of movable tube sheets heat exchanger floating tubesheet end hydraulic testing stuffing box, when movable tube sheets heat exchanger carries out the pipe adapter leak detection, can form stationary tubesheet, housing, heat exchanger tube and floating tubesheet the cavity of a sealing effectively, check that quick and precisely situation is leaked in the connection of each pipe adapter.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of movable tube sheets heat exchanger floating tubesheet end hydraulic testing stuffing box, and the box flange of described stuffing box connects with heat exchanger shell, seals with rubber sheet gasket between the two; Has the heat exchanger tube tube bank in heat exchanger shell and the stuffing box casing, floating tubesheet is positioned at stuffing box, the inside surface that the casing shell ring contacts with floating tubesheet has an annular groove, asbestos packing and taper snap ring are set in the space between floating tubesheet and the annular groove, and gland shell ring the inner compresses and leans on the taper snap ring; Box flange is connected by screw rod with gland flange, the pretightning force that screw rod produces passes to taper snap ring and asbestos packing by gland flange, gland shell ring, and asbestos packing is subjected to crowded radial dilatation to be adjacent to the floating tubesheet cylindrical and casing shell ring inside surface reaches sealing purpose.

The surface of contact of described taper snap ring and gland shell ring is 45 ° of inclined-planes, make the taper snap ring not only produce axial force but also produce radial force, axial force compresses asbestos packing, radial force passes to floating tubesheet, the downward off-centre that floating tubesheet produces because of gravity is carried out the radial location adjusting, guarantee that floating tubesheet and stuffing box cabinet wall gap as far as possible evenly, more help the sealing effectiveness of stuffing box.

The inner face that the casing shell ring of described stuffing box contacts with asbestos packing is processed hypotenuse at 45, makes the casing shell ring produce radial component to asbestos packing, strengthens the be adjacent to power of asbestos packing to the floating tubesheet periphery.

Described stuffing box box flange, casing shell ring, gland flange, gland shell ring, taper snap ring adopt structural carbon steel, box flange and casing shell ring, and gland flange and gland shell ring adopt and are welded to connect.

The beneficial effects of the utility model are: be applicable to the movable tube sheets heat exchanger floating tubesheet pipe adapter water pressure leak detection test of the following different-diameter of test pressure 10MPa, simple in structure, low cost of manufacture, good practical effect.
