Abstract
The utility model discloses a kind of large-scale door gas-flow closure circles, it includes：Sealing ring mounting groove, gas-flow closure circle；Wherein, the sealing ring mounting groove is fixed on warehouse wall, the gas-flow closure circle is embedded in the sealing ring mounting groove, charge and discharge gas nozzle is stretched out from the sealing mounting groove, when inflated condition, the gas-flow closure circle dilatancy, wherein cardiac prominence face are tightly bonded by pressure with hatch door, and gap between warehouse wall and door is blocked；The utility model uses inflation seal ring, by way of inflating pressure, the gap between warehouse wall and door is blocked, the tension of gas and the ductility of rubber are utilized, always it fits closely, effective solution due to it is poorly sealed it is close caused by sealing medium leakage and squeeze problem destroyed to the irrecoverability that sealing element generates, raising service life is reusable, reduce the turnover rate of sealing element, more environmentally-friendly, energy saving, sealing is more tight, safe and efficient.
Description
Technical field
The utility model is related to sealing device field, more particularly to a kind of large-scale door gas-flow closure circle.
Background technology
Nowadays, the sealing strip that market uses at present is to go crush seal item to reach sealing purpose by door, but due to door
It is oversized, by process, assembly precision is influenced, or deformation of expanding with heat and contract with cold is generated by variation of ambient temperature, cause its needs
The gap of sealing is also inconsistent, or perhaps change, it is difficult to reach ideal sealing effect using conventional seals item, be easy to
Cause poorly sealed to make sealing medium leak, especially dangerous material leak, and can be caused to environment and the person immeasurable
Consequence.Since conventional sealing principle is to reach sealing purpose by two workpiece squeeze sealing members, this extruding is to destroy
Property, that is to say, that sealing element is disposable, undoubtedly causes prodigious waste.
Therefore it is strong how to provide a kind of leakproofness, it is reusable, it firmly installs, safe and efficient, energy-saving and environment-friendly large size
The problem of door gas-flow closure circle is those skilled in the art's urgent need to resolve.
Utility model content
In view of this, the utility model provides a kind of strong with leakproofness, reusable, safe and efficient, energy-saving ring
The large-scale door gas-flow closure circle of guarantor's feature.
To achieve the above object, the utility model provides the following technical solutions：
A kind of large size door gas-flow closure circle, which is characterized in that it includes：Sealing ring mounting groove, gas-flow closure circle；Its
In, the sealing ring mounting groove is fixed on warehouse wall, and the gas-flow closure circle is embedded in the sealing ring mounting groove, inflation/deflation
Mouth is stretched out from the sealing mounting groove, and when inflated condition, the gas-flow closure circle dilatancy, wherein cardiac prominence is appeared by pressure
It is tightly bonded with hatch door, blocks gap between warehouse wall and door.
Preferably, in a kind of above-mentioned large-scale door gas-flow closure circle, the gas-flow closure circle is equipped with single or multiple
Air inflation nozzle.
Preferably, in a kind of above-mentioned large-scale door gas-flow closure circle, the inflation puts mouth from the sealing mounting groove
Middle stretching.
Preferably, in a kind of above-mentioned large-scale door gas-flow closure circle, the gas-flow closure circle sealed end contact surface is
Center convex shape, protrusion plane are serrated face.
Preferably, in a kind of above-mentioned large-scale door gas-flow closure circle, gas-flow closure circle bottom is dovetail shaped.
Preferably, in a kind of above-mentioned large-scale door gas-flow closure circle, conventional pneumatic can be used in the gas-flow closure circle
Low pressure limit and the upper limit is arranged in pressure-retaining system, carries out qi of chong channel ascending adversely pressurization automatically when pressure reaches low pressure limit, pressure reaches pressure
Stop when the upper limit.
It can be seen via above technical scheme that compared with prior art, the utility model is led to by the way of inflating pressure
Gas overcharging makes gas-flow closure circle dilatancy, fills up the gap between warehouse wall and door, solves by extrusion type sealed to close
Destruction that sealing generates and since door is oversized, by process, assembly precision is influenced, or generated by variation of ambient temperature
It expands with heat and contract with cold deformation, causes its gap variation constantly variation, the problem of caused poorly sealed, sealing medium leaks, more pacify
Overall height is imitated, and the inflating pressure formula sealing used keeps sealing element reusable, reduces breakage rate, and energy conservation and environmental protection can also adopt
The gap of bigger is sealed with the sealing strip of small cross sections size, applicability is stronger.
