Abstract
A kind of aviator's life support anti-lotus subsystem testing fixture, comprising: collar, boss, connecting pin, lug, briquetting, rider and lever; Lever front end by connecting pin and projection hinged, projection welds with collar, and collar is fixed on aircraft anti-G valve; Briquetting is positioned at collar, and briquetting is upwards welded on the position near front end on lever by lug; Rider is socketed on lever, and rider can along lever slips, and lever surface indicates force value scale.The original position inspection method that the utility model provides utilizes lever assembly, completes the transfer in force space, breaches the restriction of measurement space, the real system that achieves original position inspection.
Description
Technical field:
The utility model belongs to flight life-support systems, particularly relates to the inspection of the anti-lotus subsystem of aviator's life support in aircraft environmental control system.
Background technology:
When receiving new machine in recent years, major part main engine plants are not equipped with special detector to the anti-lotus subsystem of aviator's life support.Should regularly or detect depending on feelings according to this system of maintenance requirement, owing to not possessing testing conditions, that is: 1. do not have suitable pressure source to enter system; 2. realize aircraft overload under quiescent conditions, and anti-G valve superjacent air space deficiency cannot place counterweight simulated aircraft overload; 3. antigravity suit outlet does not have instrument, lacks special measurement device.Therefore, current method only has anti-G valve to off normal and returns factory or more renew part, does the original state not only destroying aircraft like this, incurs loss through delay and take a flight test the cycle, simultaneously will bring larger maintenance load because the accessibility of the core component anti-G valve of system is poor, and easily cause maintenance mistake.
Summary of the invention
The purpose of this utility model is: propose a kind of aviator's life support anti-lotus subsystem testing fixture, realize the original position inspection of aviator's life support anti-lotus subsystem parts, that is: do not need dismounting parts to carry out systemic-function detection.
The technical solution of the utility model is: a kind of aviator's life support anti-lotus subsystem testing fixture, is characterized in that, comprising: lever assembly, compression indicator and buffer container;
Wherein, lever assembly comprises: collar, boss, connecting pin, lug, briquetting, rider and lever;
Lever front end by connecting pin and projection hinged, projection welds with collar, and collar is fixed on aircraft anti-G valve; Briquetting is positioned at collar, and briquetting is upwards welded on the position near front end on lever by lug; Rider is socketed on lever, and rider can along lever slips, and lever surface indicates force value scale;
Compression indicator is connected with buffer container and is then connected on aircraft anti-G valve delivery conduit.
The utility model has the advantages that:
1: the utility model carries out equivalency transform to existing detection technique, do not need to dismantle parts, just can realize the original position inspection of the anti-lotus subsystem of aviator's life support.The original position inspection method that the utility model provides utilizes lever assembly, completes the transfer in force space, breaches the restriction of measurement space, the real system that achieves original position inspection.Relatively with traditional inspection method of offing normal, original position inspection method has does not incur loss through delay the cycle of taking a flight test, the advantages such as human error's probability of occurrence is low.
2: the anti-g protective system working gas when source of the gas that the utility model adopts is engine test, breach parts and to off normal the limitation of static check, reflect system dynamic operational behaviour really.
Accompanying drawing explanation
Accompanying drawing 1 is the lever assembly schematic diagram of a kind of aviator of the utility model life support anti-lotus subsystem testing fixture.
Accompanying drawing 2 is the utility model device inspection connection diagram.
Detailed description of the invention:
As shown in Figure 1: a kind of aviator's life support of the utility model anti-lotus subsystem testing fixture, comprising: lever assembly, compression indicator 14 and buffer container 15;
Wherein, lever assembly comprises: collar 1, boss 3, connecting pin 4, lug 5, briquetting 6, rider 7 and lever 8;
Lever 8 front end is hinged by connecting pin 4 and projection 3, and projection 3 welds with collar 1, and collar 1 is fixed on aircraft anti-G valve; Briquetting 6 is positioned at collar 1, and briquetting 6 is upwards welded on the position near front end on lever 8 by lug 5; Rider 7 is socketed on lever 8, and rider 7 can be slided along lever 8, and lever 8 surface indicates force value scale.Position shown in 2 is lever assembly Output pressure point.Change rider 7 position, i.e. convertible delivery pressure value.
Compression indicator 14 is connected with buffer container 15 and is then connected on aircraft anti-G valve 12 delivery conduit.
The method of attachment of aviator's life support anti-lotus subsystem detecting device as shown in Figure 2, during use, collar 1 is fixed on aircraft anti-G valve 12, the lever assembly Output pressure point 2 of briquetting 6 bottom withstands on anti-G valve 12 upper surface, anti-G valve 12 is positioned at passenger cabin 11, change the position of rider 7 for simulating different aircraft overloads, briquetting 6 moves downward pressure anti-G valve 12 being applied to different size.Be connected on anti-G valve 12 delivery conduit by compression indicator 14 and buffer container 15, compression indicator 14 shows anti-G valve 12 delivery pressure simultaneously, and buffer container 15 is used for the delivery pressure of stable anti-G valve 12, makes the stable reading of compression indicator 14.By reduced pressue meter reading and specified value, the original position inspection of the anti-lotus subsystem of aviator's life support can be completed.
