The covering device can be reduced effectively need to carry out the water consumption of hydrostatic test because the equipment mouth of pipe goes out modification.Saved into
Product, reduce the waste of water resource.The step of also simplify to carrying out hydrostatic test at boiler and pressure vessel butt tube.
Brief description of the drawings
Fig. 1 is the front view for carrying out the device of local hydrostatic test at equipment adapter.
Wherein：1 tensioning threaded rods, 2 tighten nut, and 3 housing seal cover plates, 4 housing seals cylinder, 5 drain taps, 6 housings are close
Packing, 7 water inlet pull bars, 8 pressure meter devices, 9 inlet valves, 10 mouth of pipe blind plates, 11 sealing blinds, 12 ferrule ring flanges.
Embodiment
An introduction is done to the specifically used form of device below according to accompanying drawing.
As shown in figure 1, a kind of device for the local hydrostatic test of progress at equipment adapter, including set through pressure vessel
The water inlet pull bar 7 of the standby mouth of pipe, water inlet pull bar can be a sealed hollow structure in two ends, and water inlet pull bar side wall is provided with water outlet
Hole.The inner that water inlet pull bar 7 is located in vessel shell A is connected with container casing sealing device B, and water inlet pull bar 7 is located at pipe
Outer end outside mouth C is provided with ferrule ring flange 12, pressure meter device 8 and inlet valve 9.Inlet valve 9 connects water inlet.
Sealing device includes housing seal cylinder 4（Sealing drum is repaired with apparatus casing contact surface according to hull shape）、
Housing seal cover plate 3, the end of housing seal cylinder 4 is provided with housing seal pad 6, and the sidepiece of housing seal cylinder 4 connects with drain tap 5
Connect, the other end of housing seal cylinder 4 is connected with housing seal cover plate 3, the center of housing seal cover plate 3 is provided with screw vent
13, the end of water inlet pull bar is connected with tensioning threaded rods 1, and tensioning threaded rods 1 pass through screw vent 13, and its end, which is screwed with, tightens nut
2。
Housing seal cover plate 3 is provided with cover drum flange disk 16, cover cylinder method provided with screw rod cover cylinder 15, the end of screw rod cover cylinder 15
Blue disk 16 is tightly connected with sealing blind 11.
The preparation before pressure testing is done first, by the sealing blind 11 in device and is tightened nut 2 and is pulled down.Then by housing
Seal cover board 3, housing seal cylinder 4, the overall enclosure interior loaded at equipment pressure testing of drain tap 5 simultaneously fill housing seal pad 6
Between pressure testing device and apparatus casing, it is ensured that pressure testing device can push down sealing gasket completely.By tensioning threaded rods 1 and water inlet pull bar
7 are attached through the equipment mouth of pipe with the pressure testing device for tightening nut 2 and device interior.Make housing by tightening nut 2
Internal pressure testing device seals gapless with apparatus casing.Then mouth of pipe blind plate 10 is loaded onto respectively with sealing blind 11, so far filled
Put and installed.
The inlet valve 9 of device and drain tap 5 are opened, by water inlet to carrying out upper water in device.Seen during upper water
Examine and see if there is water seepage at housing seal pad 6, mouth of pipe blind plate 10 and sealing blind 11.Such as mouth of pipe blind plate 10, sealing blind 11
Locate leak, the bolt what connected is further tightened.As found to be needed at housing seal pad 6 if leak by sealing blind
11 pull down, and to tightening nut 2 tighten until housing seal pad 6 not untill leak.When drain tap 5 has water outlet, close
Water on drain tap 5 is closed to terminate.Upper water can be pressurized at inlet valve 9 to equipment on request after terminating, and be closed during pressurize
Inlet valve 9.Such as find that the situation for having leak repeats above step and device is fastened in supercharging.Supercharging and
The water pressure test can be monitored according to the reading on pressure meter device 8 during pressurize.
As can be seen from the above step, water used in device is only a seldom part, it is possible thereby to save a large amount of
Use water.Because device is only detected to a mouth of pipe, eliminate other and installed without detecting that the sealing blind of the mouth of pipe is processed
And the work such as pull down.So as to simplify the workload of hydrostatic test.
Embodiment of the present utility model is described above in association with accompanying drawing, but these explanations can not be understood to
Scope of the present utility model is limited, protection domain of the present utility model is limited by appended claims, any in this reality
All it is protection domain of the present utility model with the change on the basis of new claim.
