Abstract
A kind of double bolloon seal pressure differential gas-tight door, is related to window technology field, and what is solved is the technical problem for avoiding poisonous gas leakage and ensureing indoor and outdoor gas differential pressure.The gas-tight door includes doorframe, door body, it is characterised in that：The door body is hinged with doorframe, and the periphery of door body is provided with two gas-flow closure circles, and the gas-flow closure circle is provided with inflation inlet, and two gas-flow closure circles are spaced laying from front to back, and each gas-flow closure circle surrounds door body one week；Gas bleeder valve and high-pressure air hose are housed, the gas outlet of the high-pressure air hose is laid between two gas-flow closure circles, and the air inlet of high-pressure air hose is connected to the gas outlet of gas bleeder valve on the doorframe.Gas-tight door provided by the utility model, the room of larger pressure difference suitable for indoor and outdoor be present.
Description
Technical field
Technology is the utility model is related to, more particularly to a kind of technology of double bolloon seal pressure differential gas-tight door.
Background technology
There is the room of pressure difference in the indoor and outdoors such as high poison, heavily contaminated, biology laboratory, its door will use hermatic door, with
Exempt from indoor harmful gas and leak to outside.Existing hermatic door all realizes sealing using common sealing gasket, is using process
In due to sealing medium aging, abrasion, failure and other reasons, definitely effectively indoor harmful gas can not be avoided to leak.
Utility model content
For defect present in above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of energy
The double bolloon seal pressure differential gas-tight door for avoiding indoor harmful gas to leak under the state of working long hours.
In order to solve the above-mentioned technical problem, a kind of double bolloon seal pressure differential gas-tight door provided by the utility model, including
Doorframe, door body, it is characterised in that：
The door body is hinged with doorframe, and the periphery of door body is provided with two gas-flow closure circles, and the gas-flow closure circle, which is provided with, to be filled
Gas port, two gas-flow closure circles are spaced laying from front to back, and each gas-flow closure circle surrounds door body one week；
Gas bleeder valve and high-pressure air hose are housed, the gas outlet of the high-pressure air hose is laid in two gas-flow closures on the doorframe
Between circle, the air inlet of high-pressure air hose is connected to the gas outlet of gas bleeder valve.
Further, the monitoring window closed with clear glass is offered in the door body.
Double bolloon seal pressure differential gas-tight door provided by the utility model, pass through two gas-flow closure circles and two gas-flow closures
Malleation between circle inflates to form three protection, effectively interior can be avoided to work long hours and cause poisonous gas leakage, and
Even if gas-flow closure circle is impaired when there is tiny leakage, the malleation inflation between two gas-flow closure circles remains to be harmful to gas in air lock
The tiny leakage of body.
Brief description of the drawings
Fig. 1 is the front view of the double bolloon seal pressure differential gas-tight door of the utility model embodiment；
Fig. 2 is that the double bolloon seal pressure differential gas-tight door of the utility model embodiment overlooks cut away view.
Embodiment
Embodiment of the present utility model is described in further detail below in conjunction with brief description of the drawings, but the present embodiment and not had to
It is every to use similar structure of the present utility model and its similar change in limitation the utility model, the utility model all should be included in
Protection domain, the pause mark in the utility model represents the relation of sum.
As Figure 1-Figure 2, a kind of double bolloon seal pressure differential gas-tight door that the utility model embodiment is provided, including door
Frame 1, door body 2, it is characterised in that：
The door body 2 is be hinged with doorframe 1, and the periphery of door body 2 is provided with two gas-flow closure circles 3, and the gas-flow closure circle 3 is set
There is inflation inlet 8, two gas-flow closure circles 3 are spaced laying from front to back, and each gas-flow closure circle 3 surrounds door body one week；
Gas bleeder valve 5 and high-pressure air hose 4 are housed, the gas outlet of the high-pressure air hose 4 is laid in two inflations on the doorframe 1
Between sealing ring 3, the air inlet of high-pressure air hose 4 is connected to the gas outlet of gas bleeder valve 5；
Handle 7 is fixed with the door body, and the monitoring window 6 closed with clear glass is offered in door body.
The utility model embodiment, the room of pressure difference suitable for indoor and outdoor be present, by handle 7 door body can be made to open, close
Close, door body can be inflated after closing using air pump to gas-flow closure circle 3, allow two gas-flow closure circles 3 to expand, and it is close to form twice
Protection is closed, prevents indoor harmful gas from leaking；And by gas bleeder valve 5, high-pressure air hose 4 to the sky between two gas-flow closure circles 3
Positive pressure air is filled with gap, the positive pressure air in the space is formed another road protection, so as to obstruct the micro- of indoor harmful gas
Leakage.
