Description
Technical field
Sealing device technical field is the utility model is related to, is specially that a kind of engine components air-leakage test high-performance is close
Seal apparatus.
Background technology
Engine be it is a kind of can the machine that can be converted into mechanical energy of other forms, including as internal combustion engine, external-combustion engine,
Motor etc..If internal combustion engine is typically that chemical energy is converted into mechanical energy.Engine components sealing performance detection when, it is necessary to
Sealed using to sealing device, existing sealing device is horizontal and vertical in gas replenishment process all to produce contraction, sealing
Effect is bad, and part of appliance is easily damaged, and needs to change 4-5 daily, and fittings cost loss is big, severe jamming production efficiency,
A kind of for this reason, it is proposed that engine components air-leakage test high-performance sealed device.
Utility model content
The purpose of this utility model is to provide a kind of engine components air-leakage test high-performance sealed device, to solve
Existing sealing device proposed in the above background technology is horizontal and vertical in gas replenishment process all to produce contraction, sealing effect
It is bad, and part of appliance is easily damaged, and needs to change 4-5 daily, fittings cost loss is big, and severe jamming production efficiency is asked
Topic.
To achieve the above object, the utility model provides following technical solution：A kind of engine components air-leakage test is high
Performance sealing device, including rubber seal rod, the inner cavity middle position of the rubber seal rod are longitudinally provided with cavity, the cavity
Intracavity bottom be plugged with it is internal be hollow structure inflation screw rod, the inner cavity top of cavity is extended at the top of the inflation screw rod
Portion, housing screw is provided with the top of the rubber seal rod, and inflation outlet is provided with the top of the outer wall of the inflation screw rod, described
The bottom of rubber seal rod is provided with inflation connector, the bottom of the inflation screw rod be connected with through inflation connector inflate into
Mouthful, the bottom of the inflation entrance is connected with gas tube, and the inner cavity of the gas tube is provided with solenoid valve.
Preferably, the outer wall bottom of the rubber seal rod is socketed with convex block.
Preferably, the housing screw is tightly connected with rubber seal rod.
Compared with prior art, the beneficial effects of the utility model are：A kind of engine components that the utility model proposes
Air-leakage test high-performance sealed device, by increasing housing screw in length direction, it is therefore prevented that the lengthwise position of sealing device
Freely stretch, improve apex seal performance, reduce since sealing effect is bad caused by original structure, accessory damage is very fast to wait band
Next puzzlement reduces accessory loss, reduces the working strength that production cost and worker bring because replacement accessory is frequent, lifting life
Efficiency is produced, reduces cancel closedown situation.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
In figure：1 rubber seal rod, 2 cavitys, 3 inflation screw rods, 4 housing screws, 5 inflation outlets, 6 inflation connectors, 7 are filled
