Description
Technical field
The utility model relates to gas-turbine combustion chamber field, particularly a kind of borescope stopper structure with flame view window.
Background technology
The casing surface of modern gas turbines firing chamber and test unit thereof be often provided with in a non-operative state for check burner inner liner inside borescope hole and in working order under for observing the flame view window of flame situation.Conventional borescope hole 101 generally only can be used for boresoope inspection and cannot carry out flame observation, and conventional flame view window 102 is due to the shortcoming of dismounting trouble, easy damaged quartz glass, general little dismounting, only for carrying out flame observation, and its range of observation also by existing hole restriction on burner inner liner exist visual range little, can only locally observe the shortcoming of whether lighting, be difficult to from macroscopical aspect observation flame virtual condition.In addition, owing to being generally furnished with in a large number for the mount pad of nozzle installation, bleed, test on the casing surface of gas-turbine combustion chamber and test unit thereof, and the distributing position of borescope hole and flame view window generally needs just to porose on burner inner liner, therefore need the locus of each mount pad to carry out reasonable layout, design difficulty increases.
Utility model content
The purpose of this utility model is not only can with in a non-operative state by the inner case of borescope equipment inspection burner inner liner, can also in working order under for observing flame situation, spy provides a kind of borescope stopper structure with flame view window.
The utility model provides a kind of borescope stopper structure with flame view window, it is characterized in that: the described borescope stopper structure with flame view window, comprises transparency silica glass 2, plug 3, sealing gasket 4, adapter 5;
Wherein: the inside by adapter 5, the quartz glass 2 and sealing gasket 4 with step being fixed to plug 3, sealing gasket 4 is for the sealing of quartz glass 2, by screwed tight and welding, plug 3 is reliably connected with adapter 5, form an entire combination part 1, the upper surface of quartz glass 2 should with plug 3 upper surface flush or a little more than plug 3 upper surface, be convenient to clear up quartz glass 2, this subassembly 1 is directly installed on combustion box 7 as plug.
Adapter 5 on subassembly 1 is extended to the floating bush 8 be fixed on burner inner liner 9 by combustion box 7, for avoiding ablation, the lower surface of adapter 5 can not stretch in burner inner liner, floating bush 8 can move within the specific limits, the problem that when working with compensation combustion room, between casing and burner inner liner, axial thermal expansion amount is inconsistent.
The perforate on burner inner liner 9 is directly aimed in hole on plug 3 and adapter 5, forms hermetically-sealed construction by the mating surface between adapter 5 and floating bush 8.
Adapter 5 is provided with air admission hole 6, a small amount of air can be caused quartz glass 2 inside surface, this air admission hole 6 is 30 ° of angles with the surface of quartz glass 2, not only can blow down the inside surface dust of quartz glass 2, and quartz glass 2 surface can also be prevented overheated.
Observation passage on adapter 5 is expansion taper hole, field range is expanded several times, or quartz glass 3 is processed as concavees lens form, increase visual range further.
Not only same mount pad can be used for boresoope inspection but also can be used for flame observation;
Quartz glass 2 and plug 3 are formed integrative-structure, and dismounting is simple;
Observation passage on adapter 5 is expansion taper hole, and field range expands several times;
Quartz glass there is step for mounting limit, Quartz glass surfaces and plug upper surface flush or a little more than plug upper surface;
Adapter 5 is furnished with many places air admission hole 6, in order to drifting dust, heat insulation;
Burner inner liner has special macropore, and is furnished with floating seal structure;
Quartz glass can be processed as concavees lens form, and suitable focal length can increase visual range further.
Advantage of the present utility model:
Borescope stopper structure with flame view window described in the utility model, can be used on aeromotor or ground gas turbine firing chamber and testpieces thereof, dismounting is simple, visual range is large, the advantage of quartz glass outside surface easy to clean.Many places air admission hole on adapter, can greatly reduce the dust attachment of quartz glass inside surface, burner inner liner have special macropore, and be furnished with floating seal structure.
