Abstract
The utility model provides a float head heat -exchanger pressure testing device. The device has welded flange and lower flange respectively at the upper and lower both ends of pressure testing barrel, is equipped with pressure testing tube bank in the pressure testing barrel, fixed end cover and gland respectively with bolt or riveting fixed on last flange and lower flange. The stiff end is covered to open there is the end cover mesopore, and it has the through -hole upward to open on the flange, and it has the draw -in groove to open on the lower flange. The improvement of the device through to ordinary frock can audio -visual control observe whether had leakage phenomenon by the tube bank of the heat exchanger of pressure testing, and the device easy operation, low cost.
Description
Technical field
The utility model relates to field of petrochemical industrial, is related specifically to a kind of pressure test device for floating head exchanger.
Background technology
Current China's economic constantly develops, and the heat interchanger development of various different types and kind is very fast, and the heat interchanger of new construction, new material continues to bring out.In order to the needs of adapt to development, the heat interchanger of Chinese heat exchanger industry to some kind establishes standard, defines series.Movable tube sheets heat exchanger is exactly one of them topmost series.Along with the enhancing of people's safety, environmental consciousness and the raising to product quality requirement, higher requirement be it is also proposed to the safe reliability of movable tube sheets heat exchanger.Pressure test is the important step in movable tube sheets heat exchanger manufacture and installation process, and in order to judge the leakage point of heat exchanger tube accurately, the reliability of structure for pressure test just becomes the key point of movable tube sheets heat exchanger.
Present stage, some chemical plant were all renew used equipment targetedly under the impact of economic overall situation.Many movable tube sheets heat exchangers are all only changed tube bank, and heat interchanger pressure testing device, to adapt to and to solve the requirement to tube bank pressure testing separately.
Summary of the invention
The purpose of this utility model is to provide one to utilize pressure testing cylindrical shell, upper flange and fixing end cap, directly observes the pressure test device for floating head exchanger of tube bank in heat interchanger whether seepage.
For achieving the above object, the technical solution of the utility model is:
A kind of pressure test device for floating head exchanger, comprise pressure testing cylindrical shell, upper flange, lower flange, fixing end cap, gland and pressure testing tube bank, described device is welded with upper flange and lower flange respectively at the two ends up and down of pressure testing cylindrical shell, pressure testing cylindrical shell is restrained built with pressure testing, and fixing end cap and gland are fixed on upper flange and lower flange with bolt or riveted joint respectively.
Described stiff end covers and has end cap mesopore, upper flange has through hole, lower flange has draw-in groove.
Good effect of the present utility model is:
1, this device is by the improvement to common frock, can monitor intuitively and observe whether had Seepage by the heat exchanger tube of pressure testing;
2, this device meets the pressure testing demand of the heat exchanger tube product of different size type;
3, this device is simple to operate, with low cost.

Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing 1-6.
See accompanying drawing 1-6, according to the specification of pressure testing tube bank 6, selected pressure testing cylindrical shell 1, then respectively upper flange 2 and lower flange 3 are welded on top and the bottom of pressure testing cylindrical shell 1, pressure testing cylindrical shell 1 is put in pressure testing tube bank 2, and the front end tube plate sealing face of pressure testing tube bank 2 is stuck on upper flange 2, the rear end tube sheet of pressure testing tube bank 2 stretches out 20-30mm from lower flange 3, again gland 5 is embedded in the draw-in groove 9 of lower flange 3, fix with fastening bolt or riveted joint, with fastening bolt or riveted joint, fixing end cap 4 is fixed on upper flange 2.In pressure testing process, can by the end cap mesopore 7 on fixing end cap 4 and the through hole 8 on upper flange 2 directly observe pressure testing tube bank 2 tube head whether have seepage to produce.Dismounting set bolt or rivet after pressure testing completes, remove fixing end cap 4 and gland 5, takes out pressure testing tube bank 6, then put into pressure testing cylindrical shell 1 by new same specification with the pressure testing tube bank 6 of size, carries out pressure testing operation by aforesaid operations process to new tube bank.
