Description
Technical field
The utility model belongs to airborne equipment technology, is related to a kind of flow increasing drainage arrangement.
Background technique
In endoatmosphere flight, when carrying out cloud flying or rainy day flight, total static pressure pick-up of aircraft needs aircraft
The water for entering stagnation pressure chamber is discharged.If water cannot be discharged, water enters stagnation pressure pipeline, and water blocking, shadow occur for pipeline when serious
The measurement to total static pressure for ringing aircraft, influences flight safety.
General drainage arrangement installs a baffle in the tube body on pick-up, by small area baffle obstructing airflow, always
Pressure passes to stagnation pressure pipeline by aperture among baffle, and water is discharged from drainage hole by air-flow；When water content is big in air,
Water can not be discharged in time, water occurs and enters stagnation pressure pipeline, influences the measurement to total static pressure of aircraft.Since design has gear
Piece, so overall weight is big.
Utility model content
The purpose of this utility model is：It is proposed a kind of flow increasing drainage arrangement, it, can applied on total static pressure pick-up of aircraft
Making the waterproof ability of total static pressure pick-up enhances, and improves the safety in utilization of total static pressure pick-up.
The technical solution of the utility model is：A kind of flow increasing drainage arrangement, including moisture separator, tube body；The aqueous vapor
Separator is composed of retardance piece, flow deflector, guide ring, and the retardance piece is opposite with the opening direction of flow deflector；The resistance
Stagnant is large semi-circular；It is higher than at horizontal plane on the flow deflector and is provided with semi-circular hole；Several drainage holes are provided on the tube body.
Further, the drainage hole is set to tube body minimum point.
Further, the retardance piece in the moisture separator, flow deflector, guide ring are by vacuum electron beam welding at one
Body.
The utility model has the advantage that and beneficial effect：The utility model flow increasing drainage arrangement, it is total after cancelling baffle
Conduit is pressed, weight is reduced；Piece is blocked using large semi-circular, increases retardance area；Stagnation pressure is passed using semicircle flow deflector
It is handed to stagnation pressure pipeline, reduces volume and weight.The utility model increases retardance area, increases displacement, securely and reliably
Property it is high.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model flow increasing drainage arrangement, and wherein Fig. 1 a figure is main view, and Fig. 1 b is to overlook
Cross-sectional view；
Fig. 2 is the structural schematic diagram of moisture separator in the utility model, and wherein Fig. 2 a figure is main view, and figure Fig. 2 b is B
Direction view, Fig. 2 c are C direction view；
Wherein, 1- moisture separator, 2- tube body, 3- drainage hole, 4- block piece, 5- flow deflector, 6- guide ring.
Specific embodiment
It elaborates with reference to the accompanying drawing to the utility model.
The utility model flow increasing drainage arrangement includes：Moisture separator 1, tube body 2.
Moisture separator includes：By retardance piece 4, flow deflector 5, guide ring 6.
The utility model designs the diameter of tube body according to pick-up volume requirement, moisture separator and tube body by weld into
Row combination；The diameter of moisture separator is determined according to internal diameter of tube body；Retardance piece 4, flow deflector 5, guide ring 6 in moisture separator
It is combined by welding.Drainage hole design designs in tube body low spot, the hole of flow deflector in tube body high point.Drainage hole is designed in pipe
Body minimum point is conducive to drain.
Moisture separator 1 has two features, functions, the feature that weight is small, retardance piece, flow deflector is abnormity, aqueous vapor separation
Device is used for blocks air, and water is prevented to enter total pressure pipeline.
2 function of tube body seals stagnation pressure chamber, keeps pressure.
The water for entering stagnation pressure chamber is discharged 3 function of drainage hole.It is provided with drainage hole on tube body 2 and is provided with two.
Block piece 4 there are three feature, function, it is semicircle, greatly retardance area, big flow the characteristics of, to entering stagnation pressure chamber
The retardance of air-flow forms stagnation pressure.
Flow deflector 5 has feature, a function, and stagnation pressure is transferred to stagnation pressure pipeline by flow deflector by semicircular feature
6 function of guide ring, fixed retardance piece and flow deflector, keep retardance piece, the opening direction of flow deflector opposite.
