Description
Technical field
The utility model is related to generator outlet sleeve technology fields, more specifically, being related to a kind of generator outlet set
Pipe air seal test tool.
Background technology
Dongfang Electric Machinery Plant 200MW generator outlets casing is because its appearance and size is huge, and failure is less in use, only factory
Family has the full performance test platform of the equipment, and the test platform is multiple functional, bulky.
Due to the use of side without the full performance test platform of the equipment, therefore the new generator of arrival is purchased for user
Outlet casing tube can not carry out experiment confirmation to the leakproofness of its generator outlet casing entirety before use, increase in use
Risk of leakage.
Therefore, in view of the above, it is those skilled in the art to invent a kind of airtight test instrument of generator outlet casing
Problem to be solved.
Utility model content
In view of the above problems, the utility model provides a kind of airtight test instrument of generator outlet casing, generator is gone out
Being effectively sealed property of thread casing is tested.
To achieve the above object, the utility model uses following technical scheme：
A kind of airtight test instrument of generator outlet casing, including ring flange, seamless steel pipe, needle-like door, bottom plate, pressure gauge
And compressed air hose, the lower end of the ring flange are welded with seamless steel pipe；The lower end of the seamless steel pipe is welded with bottom plate；It is described
Needle-like door there are two being opened up on seamless steel pipe；It is separately installed with pressure gauge and compressed air hose in the needle-like door.
Further, the edge of ring flange upper end inner ring is provided with seal groove.
Further, the seal groove is the chamfering of 10mm × 45 °.
Further, the diameter of the seamless steel pipe is more than the diameter of ring flange inner ring.
Further, the diameter of the bottom plate is more than the diameter of flange plate outer ring.
The utility model has the beneficial effects that：The airtight test instrument of generator outlet casing have it is small, light-weight,
Advantage easy to carry, the present apparatus can test being effectively sealed property of generator outlet casing.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram one of airtight test instrument of generator outlet casing described in the utility model；
Fig. 2 is a kind of structural schematic diagram two of airtight test instrument of generator outlet casing described in the utility model；
In figure, 1, ring flange；2, seamless steel pipe；3, needle-like door；4, bottom plate；5, pressure gauge；6, compressed air hose；101, close
Sealing groove.
Specific implementation mode
The utility model is specifically described below in conjunction with the accompanying drawings, as shown in Figs. 1-2, a kind of generator outlet casing gas
Close test instrument, including ring flange 1, seamless steel pipe 2, needle-like door 3, bottom plate 4, pressure gauge 5 and compressed air hose 6, the flange
The lower end of disk 1 is welded with seamless steel pipe 2；The lower end of the seamless steel pipe 2 is welded with bottom plate 4；It is offered on the seamless steel pipe 2
Two needle-like doors 3；It is separately installed with pressure gauge 5 and compressed air hose 6 in the needle-like door 3.
In order to preferably realize that the utility model, the edge of 1 upper end inner ring of the ring flange are provided with seal groove 101.
In order to preferably realize that the utility model, the seal groove 101 are the chamfering of 10mm × 45 °.
In order to preferably realize that the utility model, the diameter of the seamless steel pipe 2 are more than the diameter of 1 inner ring of ring flange.
In order to preferably realize that the utility model, the diameter of the bottom plate 4 are more than the diameter of 1 outer ring of ring flange.
In the present embodiment, by the good flange gasket of generator outlet casing cushion, it is mounted on generator outlet casing gas
It fastens on close test instrument, then connect compressed air hose 6 with compressed air source；Then compressed air valve is opened to power generation
Inflating pressure in machine outlet casing tube air seal test tool stops pressurization when pressure gauge 5 reaches specified pressure 0.3Mpa, stands
The airtight test instrument skin temperature of generator outlet casing is recorded after 0.5 hour and pressure gauge 5 is read；Remember again after spending 8 hours
It records the airtight test instrument skin temperature of generator outlet casing and pressure gauge 5 is read, read by pressure gauge 5 and calculate sky in container
Gas amount of leakage, and generator outlet bobbin seal performance is evaluated with this.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art
Personnel embody the principles of the present invention to some variations that some of which part may be made, and belong to the utility model
Protection domain within.
