It is easy to scratch cylinder inboard wall；And if pressure testing result is unqualified, needs to restrain pulling out from cylinder, be easier in this way
Cylinder inboard wall is scratched.So currently used pressure testing mode is：It needs in addition to manufacture and restrains matched pressure testing shell with pressure testing,
Then tube bank is sent into pressure testing shell, then tube sheet and pressure testing housing seal that both ends will be restrained, is then led into pressure testing shell
Enter pressure-air or high pressure water, so that the pressure in pressure testing shell is reached testing requirements, staff is to the pressure in pressure testing shell
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.
Summary of the invention
The object of the present invention is to provide one kind, and carrying can be facilitated to restrain and tube bank is made to scratch cylinder inboard wall, thus
The Pipe bundle structure convenient for pressure testing that pressure testing is carried out in cylinder can be made to restrain.
To achieve the above object, the technical scheme adopted by the invention is that：Convenient for the Pipe bundle structure of pressure testing, including：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 of heat exchanger tube respectively with two pieces
Tube sheet sealing welding is fixedly installed a supporting guide between two tube sheets, and supporting guide is located at the lower section of tube sheet, support
Guide rail is also fixedly connected with baffle plate, and several support wheels that can be freely rotated are provided on supporting guide, and support wheel is downwardly convex
For supporting guide, it is fixedly installed a pressure testing baffle ring respectively on two pieces of tube sheets, pressure testing baffle ring can be close with cylinder inboard wall
Soldering and sealing connects.
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.
It is an advantage of the invention that：Support wheel is provided with below tube bank can facilitate tube bank disengaging cylinder, and pass in and out
Cylinder inboard wall will not be scratched when cylinder, so there is no need to damage cylinder inboard wall in order to prevent and additionally prepare pressure testing shell into
Row work pressure test, staff can carry out work pressure test to tube bank directly in cylinder, not only increase working efficiency, also drop
Low 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 of the present invention 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 of the present invention convenient for pressure testing.
Specific embodiment
With reference to the accompanying drawing and preferred embodiment is further described technical solutions according to the invention.
As shown in Figure 1, Figure 2, Figure 3 shows, the Pipe bundle structure of the present invention convenient for pressure testing, including：Tube sheet 1, several bafflings
Plate 2, several heat exchanger tubes 3 are vertically fixedly connected with a controlled interval pull rod 11 on one piece of tube sheet 1, are arranged on controlled interval pull rod 11
There are several locating slots, the spacing between each adjacent two locating slot is exactly the spacing between each adjacent two baffle plate 2, baffle plate
2 are fixed on corresponding locating slot one by one respectively, thus guarantee in the installation process of baffle plate 2 baffle plate 2 and baffle plate 2 it
Between spacing be not in deviation, several fixed plates 21 are fixedly installed on the baffle plate 2 being fixed on controlled interval pull rod 11, Gu
Fixed board 21 can fix with each other adjacent baffle plate 2, and the both ends of heat exchanger tube 3 are managed with two pieces respectively after passing through several baffle plates 2
