Specific embodiment
The utility model is described in further details below with reference to accompanying drawings and embodiments:
[embodiment 1]
As shown in Figure 1, Figure 2 and shown in Fig. 5, a kind of transfer chamber hermatic door, including between high pressure cabin and low pressure cabin
Doorframe 1 and the door-plate 3 to match with doorframe 1, wherein doorframe 1 and transfer chamber cabin one, 3 side of door-plate by hinge 4 with
Doorframe 1 is located at a side connection in high pressure cabin, and door-plate 3 and 1 contact position of doorframe have sealing strip 5.
Wherein high pressure cabin is made a living cabin living, and low pressure cabin is transfer chamber, and in use, accommodation and transfer chamber are to connect
Logical, transfer chamber is consistent with accommodation pressure, and the effect that at this moment door-plate 3 is not under pressure be free to open and close；
When personnel want away in accommodation it is necessary to first close hermatic door, personnel are rested in transfer chamber, and transfer chamber is let out
At this moment pressure generates pressure difference before transfer chamber and accommodation, under pressure, door-plate 3 is by the power to transfer chamber direction, quilt
It is pressed on doorframe 1, and compresses the sealing strip on doorframe 1, realize sealing structure, transfer chamber is isolated with accommodation, it is easily real
Now seal.
When personnel want to enter in accommodation, it is introduced into transfer chamber, at this moment transfer chamber pressure is low, and accommodation pressure is high, close
Closure door closes under the effect of the pressure, and then transfer chamber pressurizes, until consistent with accommodation pressure, at this moment hermatic door not by
The effect of pressure will be pushed open and can be entered in accommodation to the door-plate 3 that accommodation is opened.
3 outer of door-plate has door-plate protrusive board 9, and edge has doorframe protrusive board 10 in doorframe 1, and when door-plate 3 is closed, door-plate is convex
Plate 9 is in contact with doorframe protrusive board 10, and the contact surface of door-plate protrusive board 9 or doorframe protrusive board 10 has sealing strip 5.
Wherein along having doorframe protrusive board 10 in doorframe 1,3 outer of door-plate has door-plate protrusive board 9, and doorframe protrusive board 10 is located at close
The side of transfer chamber, door-plate protrusive board 9 are located at the side of accommodation.In this way when there is pressure difference, it is convex that door-plate protrusive board 9 is pressed on doorframe
On plate 10, and the contact surface of door-plate protrusive board 9 or doorframe protrusive board 10 has sealing strip 5, and door-plate protrusive board 9 and doorframe protrusive board 10 are mutual
Sealing strip 5 is squeezed, so that accommodation and transfer chamber atmosphere draught-free, are realized closed.
The thickness of the door-plate protrusive board 9, sealing strip 5 and doorframe protrusive board 10 and thickness phase with door-plate 3 or doorframe 1
Together.So that the entirety of door-plate protrusive board 9, sealing strip 5 and doorframe protrusive board 10 will not be protruded outside doorframe 1, it is not only beautiful, but also do not influence close
The opening and closing of closure door.
[embodiment 2]
The 1 high pressure cabin side of doorframe is also connected with Prssure lock 2, and the tapered end 6 of Prssure lock 2 is in contact with door-plate 3,
Middle Prssure lock 2 is located at one side opposite with hinge 4 on doorframe 1.Wherein doorframe 1 is also connected with Prssure lock 2 in high pressure cabin side,
Prssure lock 2 is connected to on the doorframe 1 of cabin one, and the tapered end 6 of Prssure lock 2 then withstands door-plate 3, and hinge 4 is located at door-plate 3
On one vertical edge, Prssure lock 2 is located on another vertical edge opposite with hinge 4.The effect of Prssure lock 2 prevents in transfer chamber
People easily just pushes door-plate 3 open very much, if someone pushes, Prssure lock 2 will withstand door, and door-plate 3 is avoided to push open again.And pressure
Lock 2 is located at opposite two sides with hinge 4, can preferably play barrier effect, does not have blocking if Prssure lock 2 and hinge 4
Effect.
There are two the Prssure lock 2 is total.
The tapered end 6 and 3 touching position of door-plate is additionally provided with spring washer 7, and spring washer 7 is connected on tapered end 6.Pressure
The position that the tapered end 6 of lock withstands door-plate 3 is additionally provided with spring washer 7, and spring washer 7 is in contact with door-plate 3.
The connecting hole 8 of the hinge 4 is waist-shaped hole.Being used to the connecting hole 8 that connect with doorframe 1 and door-plate 3 on hinge 4 is
Waist-shaped hole, doorframe 1 are connect with door-plate 3 by hinge 4, are allowed in doorframe 1 and door-plate 3 in the case where closing naturally, in
Between there are gaps, in this way in the case where no pressure, doorframe 1 is to separate with door-plate 3, is easy to open, and only need stitching
Upper sealing strip is filled in gap, can realize simultaneously closing in the case where easy open.
The sealing strip 5 is with a thickness of 2mm.In the case where Natural closure, the gap between doorframe 1 and door-plate 3 is
2mm, for fill the sealing strip 5 in gap then with gap stack pile.
To sum up, when in use, accommodation and transfer chamber are in identical hyperbaric environment, there is no pressure between two cabins
Difference, door-plate 3 is not by pressure, and hermatic door is in the state arbitrarily opened and closed, and personnel move freely between two cabins.
When personnel will go out in cabin, it is closed door-plate 3, personnel enter in transfer chamber, transfer chamber pressure release, at this moment at accommodation
In high pressure, transfer chamber is in low pressure, and under the action of pressure difference, door-plate 3 is by the pressure toward transfer chamber direction, door-plate protrusive board 9
It is pressed on the sealing strip 5 of doorframe protrusive board 10, the sealing strip of extruding opens two cabin isolations.After transfer chamber pressure release,
Personnel are gone out by the transfer chamber other end.
When personnel out of my cabin will enter in accommodation, into transfer chamber, at this moment transfer chamber is in the environment of low pressure, and door-plate
Protrusive board 9 is then pressed on the sealing strip 5 of doorframe protrusive board 10, after personnel enter transfer chamber, is pressurizeed to transfer chamber, until with life
With pressing, the pressure that the personnel of transfer chamber then slowly adapt to improve does not have when transition lock pressure power is consistent with accommodation pressure in cabin living
Pressure difference, door-plate protrusive board 9 is not just by pressure, door-plate protrusive board 9 is separated with doorframe protrusive board 10, and transfer chamber personnel push door-plate 3 open i.e.
It can enter in accommodation.
