Description
Technical field
The utility model relates to mechanical equipment technical fields, and in particular to a kind of airbag sealing unit.
Background technique
Carbon dioxide commercial is widely used, generally goes through pipeline and is filled in air bag and is stored.In common design,
Air bag inlet and outlet with pipeline junction envelope seal form be duct orientation on hose clamp by air bag fixing seal on pipeline, but by
It can move up and down in air bag, interface is caused to be also easy to produce gap, poor sealing effect, so that outside air easily enters air bag, system
Interior carbon dioxide purity decline.Therefore, it is necessary to a kind of new Seal Designs, even if so that air bag up and down motion, will not influence
System sealing avoids carbon dioxide purity in system from declining.
Utility model content
The purpose of the utility model is to provide a kind of dioxide capsule sealing devices, solve at least one above skill
Art problem.
The technical issues of the utility model is solved can be realized using following technical scheme:
Dioxide capsule sealing device, including airbag body, which is characterized in that at the air inlet/outlet of the airbag body
Flange with outward extension, embedded with a disengaging tracheae, the outside of the flange is equipped with sealing device for the inside of the flange；
The sealing device includes upper flange plate and lower flange, and the lower flange is fixed on outside the disengaging tracheae
Side, the upper flange plate are rotatably sleeved on the outside of the disengaging tracheae；
The edge of the flange is embedded in the gap of the upper flange plate and the lower flange, the upper flange plate and institute
It states lower flange to be bolted, compress and fixes the flange.
The utility model squeezes the flange of fastening airbag body by ring flange, and then disengaging tracheae is fixed on flange
Inside facilitates operator that pressure gauge, charger etc. are connected with airbag body by disengaging tracheae, shortens air bag
Assembly time.Meanwhile flange arrangement compares general sealing structure, is able to bear bigger pressure, guarantees at disengaging tracheae
Air-tightness, even if air sac sealing will not be influenced, carbon dioxide purity is avoided in air bag to decline so that air bag moves up and down.
Optionally, the length of the flange is 25~30mm.
Optionally, the diameter of the disengaging tracheae is 130mm, and the length of the disengaging tracheae is 330~370mm.Optimization
The size of flange and disengaging tracheae, saves material, save the cost.
Optionally, the semicircle that the tube wall edge of the disengaging tracheae is 0.5mm in radius.
Airbag body is usually made of rubber material, is easy to be punctured, scratch.Tube wall edge semicircular in shape, then be not easy
It damages on the inside of flange.
Optionally, outer diameter greatly at least 15mm of the diameter of the upper flange plate inner ring than the disengaging tracheae.In order to turn over
Side passes through the inner ring of upper flange plate.
Optionally, gasket is equipped between the upper flange plate and the lower flange, the thickness of the gasket is less than described
The thickness of the cyst wall of airbag body.
Gasket can prevent excessive compression flange between upper and lower ring flange, and flange is caused to damage, and influence the airtight of air bag
Property.
Optionally, the contact surface of the upper flange plate and flange is equipped with the trapezoidal sawtooth in several sections.
Sawtooth is embedded in flange after bolt is fixed in upper and lower ring flange, to further fix flange, avoids flange
It falls off.
Detailed description of the invention
Fig. 1 is a kind of sectional view of the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face, which combines to be specifically illustrating, is further described the utility model.
Referring to Fig.1, dioxide capsule sealing device, including airbag body 1 are equipped at the air inlet/outlet of airbag body 1
Outwardly extending flange 2, embedded with a disengaging tracheae 3, the outside of flange 2 is equipped with sealing device for the inside of flange 2；Sealing device packet
Include upper flange plate 4 and lower flange 5, lower flange 5 is fixed on 3 outside of disengaging tracheae, upper flange plate 4 be rotatably sleeved on into
3 outside of escape pipe；In the edge insertion upper flange plate 4 of flange 2 and the gap of lower flange 5, upper flange plate 4 and lower flange 5
It is bolted, compresses and fixes flange 2.The utility model squeezes the flange 2 of fastening airbag body 1 by ring flange, into
And disengaging tracheae 3 is fixed on to the inside of flange 2, facilitate operator by passing in and out tracheae 3 for pressure gauge, charger etc.
It is connected with airbag body 1, shortens the assembly time of air bag.Meanwhile flange arrangement compares general sealing structure, Neng Goucheng
By bigger pressure, guarantee the air-tightness at disengaging tracheae 3, even if air sac sealing will not be influenced so that air bag moves up and down,
Carbon dioxide purity in air bag is avoided to decline.
The length of flange 2 is 25~30mm.Pass in and out tracheae 3 diameter be 130mm, disengaging tracheae 3 length be 330~
