It tests, if the intracorporal pressure of pressure testing shell remains unchanged within a certain period of time, illustrates in tube bank between exchanger tubes and tubesheets
Welding quality it is qualified, qualified tube bank can thus be put into the cylinder of large container；If pressure testing shell within a certain period of time
Intracorporal pressure is gradually reduced, then illustrates that the welding quality in tube bank between exchanger tubes and tubesheets is unqualified, need to exchange heat pipe
It is checked and is rewelded in welding position between tube sheet.Above-mentioned this pressure testing mode needs to be manufactured according to the tube bank of different size
Different pressure testing shells, a large amount of pressure testing shell not only increases production cost, but also also takes up a large amount of warehouse space.
Utility model content
The purpose of the utility model is to provide one kind, and carrying can be facilitated to restrain and tube bank is made to scratch cylinder inboard wall,
So as to make to restrain the Pipe bundle structure convenient for pressure testing for carrying out pressure testing in cylinder.
To achieve the above object, the technical scheme adopted by the utility model is being convenient for the Pipe bundle structure of pressure testing, comprising:
Tube sheet, several baffle plates, several heat exchanger tubes, heat exchanger tube, which is worn, to be fixed in several baffle plates, and the both ends difference of heat exchanger tube
With two pieces of tube sheet sealing weldings, a supporting guide is fixedly installed between two tube sheets, supporting guide is located under tube sheet
Side, supporting guide are also fixedly connected with baffle plate, and several support wheels that can be freely rotated, support wheel are provided on supporting guide
Downwardly projecting to be fixedly installed a pressure testing baffle ring respectively on two pieces of tube sheets in supporting guide, pressure testing baffle ring can be with cylinder
Inner wall sealing welding.
Further, the Pipe bundle structure above-mentioned convenient for pressure testing a, wherein spacing is vertically connected on one piece of tube sheet
Pull rod, is provided with several locating slots on controlled interval pull rod, and the spacing between each adjacent two locating slot is exactly each adjacent two folding
Spacing between flowing plate, baffle plate are fixed on corresponding locating slot one by one respectively.
Further, the Pipe bundle structure above-mentioned convenient for pressure testing, wherein solid on the baffle plate being fixed on controlled interval pull rod
Surely several fixed plates are provided with, fixed plate can fix with each other adjacent baffle plate.
Further, the Pipe bundle structure above-mentioned convenient for pressure testing, wherein be located between per two adjacent baffle plates
A support wheel is provided on supporting guide.
Further, the Pipe bundle structure above-mentioned convenient for pressure testing, wherein connected between pressure testing baffle ring and tube sheet by welding
It connects.
The utility model has the advantages that: support wheel is provided with below tube bank can facilitate tube bank disengaging cylinder, Er Qie
Cylinder inboard wall will not be scratched when passing in and out cylinder, additionally prepares pressure testing shell so there is no need to damage cylinder inboard wall in order to prevent
Body carries out work pressure test, and staff can carry out work pressure test to tube bank directly in cylinder, not only increase working efficiency,
Also reduce production cost；In addition, during pressure testing, pressure testing baffle ring is mutually welded with cylinder and prevents from tube sheet and is damaged.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the Pipe bundle structure described in the utility model convenient for pressure testing.
Fig. 2 is the enlarged structure schematic diagram in the direction A in Fig. 1.
Fig. 3 is the part planar structural representation of the Pipe bundle structure described in the utility model convenient for pressure testing.
Specific embodiment
With reference to the accompanying drawing and preferred embodiment is further described technical solution described in the utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, the Pipe bundle structure described in the utility model convenient for pressure testing, comprising: tube sheet 1, several
Baffle plate 2, several heat exchanger tubes 3 are vertically fixedly connected with a controlled interval pull rod 11, on controlled interval pull rod 11 on one piece of tube sheet 1
Several locating slots are provided with, the spacing between each adjacent two locating slot is exactly the spacing between each adjacent two baffle plate 2, folding
Flowing plate 2 is fixed on corresponding locating slot one by one respectively, to guarantee baffle plate 2 and baffling in the installation process of baffle plate 2
Spacing between plate 2 is not in deviation, is fixedly installed several fixed plates on the baffle plate 2 being fixed on controlled interval pull rod 11
21, fixed plate 21 can fix with each other adjacent baffle plate 2, and the both ends of heat exchanger tube 3 pass through after several baffle plates 2 respectively with two
