Abstract
A kind of gas-flow closure circle, it includes sealing ring body and gas tube, sealing ring body is the hollow circular ring i.e. annulus revolving body that the section made of elastic material is annulus, the annulus revolution body wall is equipped with a through-hole, that is, aeration aperture, which is equipped with the same material inflating catheter being linked together with it.The configuration of the present invention is simple, reliable performance；The sealing problem that can solve Cryo Equipment and larger transport devices extends their service life, not only reduces maintenance cost, but also decreases because of many troubles brought by maintenance.
Description
The present invention relates to a kind of machinery sealing rings for technical field.
Background technique is it is well known that the sealing between mechanical equipment component generallys use sealing ring to realize.Described is close
Seal is all made of flexible material and is made, though diameter, sectional dimension and shape are had nothing in common with each other, they are reality
Core structure.Its shortcoming is: it applies and is easy leakage under certain special operation conditions, under cryogenic such as prolonged application, by
Thermal expansion and contraction principle restricts, and sealing ring, which can be deformed, leads to gas leakage；The for another example large component of prolonged application in the dynamic case
Such as the hermatic door of driving vehicle, gap can be generated under quick jounce condition, the own resilient of existing sealing ring cannot be same with it
Step restores reset condition, also results in gas leakage.
The purpose of the present invention is to provide one kind, and low temperature and dynamic large component can be made to keep close for a long time for summary of the invention
The gas-flow closure circle of envelope.The present invention is used for low pressure (below 10 atmospheric pressure) state.
The invention mainly comprises sealing ring body and gas tubes.Wherein, sealing ring body is cut made of elastic material
Face is hollow circular ring, that is, annulus revolving body of annulus, which is equipped with a through-hole, that is, aeration aperture, the aeration aperture
It is equipped with the same material inflating catheter being linked together with it.The elastic material are as follows: nitrile rubber, silicon rubber, neoprene, third
Olefin(e) acid rouge rubber, polyurethane rubber and natural rubber.
It will the suitable thickness of the selection of the operating condition according to locating for sealing ring and material before.In use, first passing through inflation
Pipe is inflated into sealing ring, is filled in aeration aperture after being full of gas by gas tube hot pressing seal, then by the gas tube after sealing, so
Gas-flow closure circle is placed on the position where it is answered afterwards.
The invention has the following advantages over the prior art:
1, the present invention can solve the sealing problem of Cryo Equipment and larger transport devices, extend their service life, no
Maintenance cost is only reduced, and is decreased because of many troubles brought by maintenance.
2, structure is simple, reliable performance.
Detailed description of the invention
Fig. 1 is main view schematic diagram of the present invention.
Fig. 2 is the B-B view of Fig. 1.
Fig. 3 is the A-A enlarged view of Fig. 1.
Specific embodiment is in the main view schematic diagram of Fig. 1 and gas-flow closure circle shown in Fig. 2, sealing ring body 1
It is the hollow circular ring i.e. annulus revolving body that the section made of nitrile rubber is annulus, which is equipped with one and leads to
Hole, that is, aeration aperture, the aeration aperture are equipped with the same material inflating catheter 2 being linked together with it, as shown in Figure 3.
