Abstract

The utility model discloses a square cooler core hydrostatic test of group frock, its characterized in that: including flange, barrel, the flange is circular flange, the barrel is circular cylinder, the flange with the port of barrel is connected, set up to the square through hole in the middle of the flange, the peripheral a week of square through hole is provided with first screw hole, be provided with the second screw hole around the flange. The utility model discloses the circular cylinder frock satisfies highly compressed hydrostatic test, and barrel rounding degree can be guaranteed effectively, can the effective control in the installation to the protection of core group fin, use seamless steel pipe, equipment when being convenient for cooler water pressure, O type circle can improve the sealed of hydrostatic test, the hydrostatic test process can inspect out that which piece heat exchange tube leaks.

Description

Square cooler core group hydraulic pressure test fixture
Technical field
The utility model relates to a kind of hydraulic pressure test fixture field, particularly relates to a kind of square cooler core group hydraulic pressure test fixture.
Background technology
The square cooler core group hydraulic testing of end-cover-free, if do not manufacture hydraulic pressure test fixture, cannot carry out the hydraulic testing, and current test method normally makes supporting end cap and carries out testing or make the square hydraulic pressure test fixture similar with core group.Make end cap and carry out the hydraulic testing, structure is simple, and easy to make, cost is lower, but cannot check out it is which root heat exchanger tube leaks, and is unfavorable for the object reaching the hydraulic testing; Make square hydraulic pressure test fixture, manufacture relatively simple, price is also more cheap, relatively good with the compatible degree of refrigeratory, easy for installation, can check out which root heat exchanger tube leaks, but square structure for pressure test assembling easily collides fin, sealing inconvenience between square flange and radiator tube plate, square cylinder cannot meet the demands, and needs again to make, cost of manufacture and production cycle can be increased, square cylinder needs the weld seam of more than twice just can complete, and very easily causes welding deformation, affects hydraulic pressure assembling.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of square cooler core group hydraulic pressure test fixture.The technical scheme that its technical solution problem adopts is: a kind of square cooler core group hydraulic pressure test fixture, and it is characterized in that: comprise flange, cylindrical shell, described flange is circular flange; Described cylindrical shell is circular cylinder body; Described flange is connected with the port of described cylindrical shell; Be set to square through hole in the middle of described flange, described square through hole periphery is provided with described first threaded hole for one week; The second threaded hole is provided with around described flange.
Preferably, also comprise an O type circle, described O type circle is arranged between described flange and described barrel port.
Preferably, described cylindrical shell is weldless steel tube.
The beneficial effects of the utility model are, circular cylinder body frock meets the hydraulic testing of high pressure, and circular degree of shell can be ensured effectively, effectively can control the protection to core group fin in installation process; Use weldless steel tube, be convenient to assembling during refrigeratory hydraulic pressure; O type circle can improve the sealing of the hydraulic testing; Hydraulic testing process can check out which root heat exchanger tube leaks.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1. flanges, 2. cylindrical shell in figure, 3. the first threaded hole, 4. the second threaded hole, 5.O type circle.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, structural representation of the present utility model, a kind of square cooler core group hydraulic pressure test fixture, is characterized in that: comprise flange 1, cylindrical shell 2, described flange 1 is circular flange; Described cylindrical shell 2 is circular cylinder body; Described flange 1 is fixedly connected with by described second threaded hole with the port of described cylindrical shell 2; Be set to square through hole in the middle of described flange 1, described square through hole periphery is provided with described first threaded hole 3 for one week; The second threaded hole 4 is provided with around described flange 1.
Also comprise an O type circle 5, described O type circle 5 is arranged between described flange 1 and described cylindrical shell 2 port.Described cylindrical shell 2 is weldless steel tube.
These are only the utility model preferred embodiment, therefore can not limit the scope of the utility model enforcement according to this, the equivalence namely done according to the utility model description changes and decoration, all should belong in the scope of the utility model covering.
