Description
Technical field
The utility model belongs to heat exchanger tube apparatus field, and in particular to a kind of double group U-tube water test units.
Background technique
In recent years, as chemical equipment production capacity constantly increases, the number of heat exchange tubes manufactured every year is continuously increased, wherein being no lack of
A large amount of U-tube heat exchangers, U-shaped heat exchanger tube main specifications have Φ 19 × 2, Φ 25 × 2.5, and original technology may only carry out list
Group set of heat exchange tubes carries out pressure testing, and the working time is longer, and such as benzene column condenser E-202, device diameters are Φ 1900, and exchange heat pipe size
It is Φ 19 × 2, number of heat exchange tubes 2187, tube layer medium is benzene, has part heat exchanger tube seriously corroded, influences styrene device
Safety in production, so must be replaced.Since the duration is tight, task weight, using the traditional mould progress water pressure test about 10 days, greatly
It is big to influence working efficiency.
Original technology may only carry out single group set of heat exchange tubes and carry out pressure testing, and the working time is longer, is unfavorable for popularization and application.Especially
, when high-volume manufactures U-tube heat exchanger, every group of U-tube must all carry out the water pressure test, seriously affect manufacturing schedule for it；If
Guarantee the duration, every group of U-tube sampling observation carries out the water pressure test, and not can guarantee the quality of production of U-tube heat exchanger.
Utility model content
The purpose of this utility model is to provide a kind of U-tube water test unit, specific technical solution is as follows:
A kind of double group U-tube water test units, including clamping and fixing device, communication seals device, locking device, sliding
Device, U-shaped set of heat exchange tubes and operating platform, clamping and fixing device and carriage are separately fixed on operating platform, will even
Logical sealing device is assembled on the dovetail groove of carriage, then locking device and carriage is welded, two groups of U-shaped set of heat exchange tubes
Clamping and fixing device is each passed through up and down in two groups of holes, and is inserted into two groups of pressure testing holes of communication seals device, then under push away clamping
Fixed device, is finally locked by locking device；It is filled the water by communication seals device water inlet, passes through connection inside communication seals device
Two groups of U-shaped set of heat exchange tubes are filled water by hole, may be implemented to carry out pressure testing to double groups of U-shaped set of heat exchange tubes simultaneously, structure is simple, is convenient for
Operation.
The beneficial effect of this practical new shape
The double groups of U-tube water test units of the utility model are suitable for hydraulic test pressure 10.1MPa or less, diameter
The U-tube water pressure test of 57mm~159mm, structure is simple, manufacturing cost is low, it is good to be applicable in effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the double group U-tube water test units of the utility model；
Specific embodiment
The utility model is described further in the following with reference to the drawings and specific embodiments.
Embodiment 1
As shown in Figure 1, a kind of double group U-tube water test units, including clamping and fixing device 1, communication seals device 2,
Locking device 3, carriage 4, U-shaped set of heat exchange tubes 5 and operating platform 6,
Clamping and fixing device 1 and carriage 4 are separately fixed on operating platform 6, the operating platform 6, there is water
Flat operating surface and waterproof overflow launder；Communication seals device 2 is assembled on the dovetail groove of carriage 4, then by locking device 3
It is welded with carriage 4, two groups of U-shaped set of heat exchange tubes 5 are each passed through in about 1 two group of hole of clamping and fixing device, and are inserted into connection
In two groups of pressure testing holes of sealing device 2, then under push away clamping bar in clamping and fixing device 1, finally locked by locking device 3；By
2 water inlet of communication seals device fills the water, and gas vent and pick-up hole are equipped at the top of the communication seals device 2, passes through connection
Two groups of U-shaped set of heat exchange tubes 5 are filled water by 2 inside intercommunicating pore of sealing device, may be implemented to carry out simultaneously double group U-shaped set of heat exchange tubes into
Row pressure testing, structure is simple, convenient for operation.
