The hydrostatic test is an indispensable link for testing the quality of the manufactured heat exchanger. In the production and manufacturing process of the floating head heat exchanger, the T-shaped floating head pressure test generally refers to the pressure test of a pipe head and the whole shell pass. Among them, pressure testing at the pipe head is an indispensable procedure. The quality of the pipe head directly influences the safe and stable operation of the heat exchanger.
The structure of the traditional T-shaped floating head pressure test tool is shown in figures 1 and 2.
The traditional T-shaped floating head pressure test tool consists of the following parts: the pressure testing device comprises a compression ring, an O-shaped ring I, a pressure testing flange, a gland, an O-shaped ring II, a backing ring, a gasket, a nut, a bolt, a gasket and other accessories.
The pressure test flange is required to be processed with grooves for placing an O-shaped ring I and an O-shaped ring II, the processing workload is large, and the processing precision requirement is high. Because the T-shaped floating head tube plate is provided with the bolt hole, the bolt hole needs to be plugged during pressure testing, and leakage is prevented. The traditional plugging mode is that after a gasket, a washer, a bolt and a nut are installed, the nut and the washer are welded firmly, and the nut and the bolt are welded firmly. The leakage stopping mode has the advantages of large welding workload, narrow operation space and inconvenient operation of welders. And after water pressure is qualified, the pressure test tool can be detached only by cutting off the bolt from the inner side, and the tool is extremely complicated and inconvenient.
Therefore, it is necessary to provide a T-shaped floating head pressure testing tool to solve the above technical problems.
SUMMERY OF THE UTILITY MODEL
Problem to among the prior art, the utility model provides a T type floats first pressure testing frock, simple structure, convenient operation, welding work volume reduces substantially, and welder intensity of labour reduces substantially, and the dismantlement work behind the water pressure is simple, convenient, swift.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a T type floats first pressure testing frock, includes the first tube sheet that floats at shell side barrel and shell side barrel both ends, be equipped with the examination clamping ring on the first tube sheet that floats of shell side barrel one end, the first tube sheet outside of floating of the other end is equipped with the extension barrel that is connected with the shell side barrel, the tip welding of extension barrel has the shrouding, and the shrouding welds with the first tube sheet that floats mutually.
Through adopting above-mentioned technical scheme, with shell side barrel length extension, make it and float first tube sheet parallel and level, adopt the shrouding sealed in float first tube sheet department, simple structure, convenient operation, welding work volume reduces by a wide margin, and welder intensity of labour reduces unprecedentedly, only needs to cut the extension barrel after hydrostatic test is qualified, then welds outer head lid side flange, dismantlement work behind the water pressure is simple, convenient, swift.
The utility model discloses a further set up to: the end of the elongated cylinder is aligned with the surface of the floating head tube plate.
Through adopting above-mentioned technical scheme, the tip that sets up the extension barrel is aligned with the surface that floats the first tube sheet, the better welding shrouding of being convenient for.
The utility model discloses a further set up to: and a cutting groove is formed in the connecting part of the lengthened cylinder body and the shell side cylinder body.
Through adopting above-mentioned technical scheme, set up and cut the groove, be convenient for along cutting better cutting of groove.
The utility model discloses a further set up to: the shrouding is the ring shape structure, just the border position of shrouding welds with the extension barrel mutually.
Through adopting above-mentioned technical scheme, set up the shrouding and be the ring annular structure, be convenient for better fix the extension barrel.
The utility model discloses a further set up to: the whole body of the sealing plate along the periphery is welded with the floating head tube plate in a sealing way.
Through adopting above-mentioned technical scheme, set up the shrouding and seal the welding along peripheral position whole and floating head tube sheet, keep device's gas tightness.
The utility model has the advantages that:
(1) a T type floats first pressure testing frock, through with shell side barrel length extension, make it and float first tube sheet parallel and level, it is sealed to adopt the shrouding in first tube sheet department of floating, simple structure, convenient operation, welding work volume reduces by a wide margin, welder intensity of labour reduces unprecedentedly. After the hydrostatic test is qualified, the lengthened cylinder body is only required to be cut off, and then the outer head cover side flange is welded, so that the disassembly work after the hydrostatic test is simple, convenient and quick.
(2) A T type floats first pressure testing frock, need not to adopt the pressure testing flange, forging materials such as clamp ring have reduced manufacturing cost by a wide margin. Because the pressure test flange, the clamp ring and other machined parts are not needed, the manufacturing period is shortened.
(3) A T type floats first pressure testing frock, through adopting shrouding welded structure in floating first tube sheet department, avoided adopting the sealed condition that appears leaking of O type circle, improved experimental success rate, save time, O type circle is sealed to be subject to the pressure restriction in addition, adopts this structure can be suitable for higher hydrostatic test pressure.
