Description

The grain depot air tight door

The utility model relates to building and uses the gate technique field, especially a kind of grain depot air tight door.

The higher building door of sealing requirements all is to be made of doorframe and door leaf at present, doorframe is by bolted splice or built-in fitting etc. link into an integrated entity with building (also have directly with wall and replace doorframe), door leaf one side is hinged by hinge and doorframe one side, be provided with the locking device that lock and locking bar constitute between door leaf or between door leaf and doorframe, be to improve sealing, people are touching the affixed rubber weather strip in position between door leaf and between door leaf and doorframe mutually.The big-and-middle-sized grain depot door doors that adopt this structure as present China various places more.There is following defective in the door of finding this structure in actual use: 1, the bad grasp of rubber weather strip thickness, and thick door leaf does not close, and has approached and do not reached sealing purpose, and especially this situation very easily appears in the upper and lower both sides of door leaf.2, because weather strip is always thicker than distance between door leaf and doorframe under free state, otherwise do not reach sealing effectiveness, so very easily cause the weather strip torsional deformation and the loss of seal performance.3, doorframe and door leaf have distortion slightly, just lose sealing function.Owing to reason such as above-mentioned, still there is not the desirable shop front generation of sealing effectiveness at present, bring many difficulties to the user; When as present big-and-middle-sized grain depot grain being carried out medicine steaming, medicament gas leaks serious, for reduce the medicament gas leak as far as possible, people have to increase sealant tape between door leaf and doorframe, not only increased the grain storage cost, and the fumigation effect is also relatively poor, is difficult to reach the high standard requirement of grain storage.

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of sealing performance high grain depot air tight door.

The purpose of this utility model realizes by following technical proposals:

Corresponding position is provided with annular groove between door leaf and doorframe and door leaf, be provided with the tracheae of the shape that adapts with it in the groove, tracheal wall and valve one end are affixed, and tube chamber communicates with the valve chamber, the valve other end be provided with gas nozzle cap and pass groove walls and be exposed to the door the outside.

Said annular groove both can be located on the door leaf periphery, also can be located on the doorframe inner peripheral,

Said groove also can be located at door leaf inner plane edge and be plane distribution, and groove location is corresponding with the outside of doorframe.

Said groove also can be located at door leaf outerplanar edge and be plane distribution, and groove location is inboard corresponding with doorframe.

Said groove also can be located at the outside of doorframe, and is corresponding with the inner plane edge of door leaf.

For prolonging the application life of tracheae, outside tracheae, be provided with one in addition.

Said annular groove is a U-lag.

For the protection tracheae, can on the corresponding member of the rotation angle position of annular groove, be provided with the semicircular arc rubber base.

During use, generally earlier door leaf is shut, and by after the locking device locking, inflate in tracheae by valve, when air pressure reached 20Kpa-80Kpa, tracheae expanded and tight filling space between doorframe and door leaf and door leaf, thereby reaches complete sealing purpose.

Dial degas mouth upper cover or valve inside when opening the door earlier, after gas is emitted in the tracheae, open locking device again, at this moment tracheae is stored in the annular groove groove automatically, opens easily.

The utility model structure adopts the confined gas principle and designs, the gap that utilizes the tracheae inflation to come to reach between door leaf and doorframe between tight filling door leaf reaches the sealing gland purpose, and open and close fashionable, not inflation in the tracheae, and be to be stored in the annular groove, thereby unlatching and pass do not close and any obstacle can occur, from above-mentioned situation as can be known the utility model purpose can realize.

Compared with prior art, the utility model has following advantage: 1, good seal performance, country is to reduce to the 250Pa half-life from 500Pa must not be lower than 40 seconds to the standard-required of sealed door, and existing sealed door is difficult to reach this requirement, the utility model detects when reality is used, it partly declines and improves tens of times to hundreds of times, and sealing effectiveness is good especially.

2, simple in structure, easy for installation, operation, maintenance are easily.

3, use the utility model when fumigation is carried out in grain storage, do not need artificial leak stopping, can reach anti-medicament and leak, reduce the grain storage cost greatly, improve the purpose of fumigation effect.
