Abstract
The utility model relates to a kind of for heat exchanger tube pass pressure testing device.Heat interchanger, after the manufacture that completes tube bank, needs to adopt the hydraulic testing to carry out ruggedness test to all mouth of pipe welding joints.Traditional heat exchanger shell pass pressure testing device tube bank seals, if tube bank sealing problem appears in whole device, heat exchanger tube integral body just there will be and leaks, and being difficult to detect which root tube bank has problem, is not easy to inspection and maintenance.For addressing the above problem, a kind of heat exchanger tube pass pressure testing device of the present utility model, comprises heat exchanger shell, with flange and the seal joint of heat exchanger shell pairing, the floating tube sheet on heat exchanger shell and stationary tubesheet.Adopt after the technical solution of the utility model, when water filling is suppressed, water just can enter tube bank by heat exchanger shell, by tube bank two ends, is flowed out, and conveniently looks into and repaiies and change.
Description
Technical field
The utility model relates to pressure vessel manufacturing inspection field, relates in particular to a kind of for heat exchanger tube pass pressure testing device.
Background technology
At pressure vessel, manufacturing field, is the security that guarantees pressure-containing member, generally adopts the mode of the hydraulic testing to carry out pressure test to the equipment after manufacturing, to guarantee pressure-containing member or the bearing capacity of welding position reaches designing requirement.Traditional heat interchanger, in order to reach the bearing capacity of design, after the manufacture that completes tube bank, needs to adopt the hydraulic testing to carry out ruggedness test to all mouth of pipe welding joints.According to the requirement of safety regulations, need carry out respectively tube side test and shell side test, to check respectively the ability to bear of mouth of pipe welding joint to tube side pressure and shell side pressure, when carrying out tube side pressure test, structure by means of casing box and floating head composition, adopt copper coin that the hot water inlet of casing box and hot water outlet are carried out carrying out the hydraulic testing after shutoff, in check heat exchanger tube bearing capacity, can check anhydrous seepage by the inner side of stationary tubesheet and floating tubesheet, to judge under tube side pressure-acting, whether the pressure-bearing of mouth of pipe welding joint is qualified, but there is larger defect in this mode, traditional heat exchanger shell pass pressure testing device tube bank seals, if there is tube bank sealing problem in whole device, heat exchanger tube integral body just there will be and leaks, but be difficult to detect any root tube bank and have problem, be not easy to inspection and maintenance.Given this, be necessary to provide a kind of heat exchanger tube pass pressure testing device, conveniently when utilizing shell side hydro-test, the weld strength of line up welding joint is tested.
Utility model content
For above object, the utility model provides a kind of heat exchanger tube pass pressure testing device, can be when carrying out shell side hydro-test, easily the mouth of pipe of stationary tubesheet and floating tubesheet is observed and checked, and can be in Tube Sheet of Heat Exchanger intrafascicular any one while occurring leaking, be convenient to on-call maintenance or replacing.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of heat exchanger tube pass pressure testing device, comprise heat exchanger shell, flange and seal joint with heat exchanger shell pairing, be arranged on floating tube sheet and stationary tubesheet on heat exchanger shell, it is characterized in that: also comprise the untight tube bank in several two ends; Wherein, described floating tube sheet and stationary tubesheet lay respectively at heat exchanger shell both sides, and the untight tube bank in described several two ends passes and runs through heat exchanger shell from floating tubesheet and stationary tubesheet.
Preferably, described floating tube sheet one side is also provided with the seal flange that diameter is greater than floating tube sheet external diameter;
Preferably, described floating tube sheet and stationary tubesheet and described heat exchanger shell are fastening by nut and double-screw bolt;
Preferably, between described floating tube sheet and stationary tubesheet and described heat exchanger shell, be also provided with O-ring seal.
Because the utility model is when designing, the untight tube bank in two ends is passed and runs through heat exchanger shell from floating tube sheet and stationary tubesheet, thus, when heat exchanger shell integral body is carried out water filling and is made a call to 1 pressure, when if occur there is sealing problem in certain tube bank, water just can enter tube bank by heat exchanger shell, by tube bank two ends, is flowed out, and conveniently looks into and repaiies and change.
Accompanying drawing explanation
According to embodiment and accompanying drawing, the utility model is described in further details below.
Fig. 1 is that heat exchanger tube pass pressure testing device described in the utility model forms structural drawing.
Concrete parts mark is as follows:
1-heat exchanger shell, 2-stationary tubesheet, 3-floating tubesheet, 4-flange, the untight tube bank in 5-two ends, 6-gasket seal baffle plate, 7-seal joint, 8-O-ring seal.
Embodiment
Below in conjunction with Figure of description, this practical preferred embodiment is described, a kind of heat exchanger tube pass pressure testing device that this practicality provides, comprise heat exchanger shell 1, flange 4 and seal joint 7 with heat exchanger shell 1 pairing, be arranged on floating tubesheet 3 and stationary tubesheet 2 on heat exchanger shell 1, wherein, also comprise the untight tube bank 5 in several two ends; Wherein, described floating tubesheet 3 lays respectively at heat exchanger shell 1 both sides with stationary tubesheet 2, and the untight tube bank 5 in described several two ends passes and runs through heat exchanger shell 1 from floating tubesheet 3 and stationary tubesheet 2.
When carrying out shell side hydro-test, for helping heat exchanger shell 1, by double-screw bolt, described floating tube sheet 3 and described stationary tubesheet 2 are carried out fastening, in floating tube sheet 3 one sides, the gasket seal baffle plate 6 that a diameter is greater than floating tube sheet 3 external diameters being set seals, the untight tube bank in two ends is passed and runs through heat exchanger shell 1 from floating tubesheet 3 and stationary tubesheet 2, thus, when heat exchanger shell 1 integral body is carried out water filling and is suppressed, when if occur there is sealing problem in certain tube bank, water just can enter tube bank by heat exchanger shell 1, by tube bank two ends, flowed out, conveniently look into and repair and change.During replacing, which root tube bank has sealing problem, directly from heat exchanger tube housing, extracts out, more renews and restrains and seal.
Finally it should be noted that: above embodiment is only in order to the technical scheme that this is practical to be described but not be limited, although this practicality is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that: it still can be modified or be equal to replacement this practical technical scheme, and these modifications or be equal to replacement and also can not make amended technical scheme depart from the spirit and scope of this practical technique scheme.
