Description

Be applied to business turn over door in pressure differential space

Technical Field

The utility model relates to a field such as building or facility with pressure differential space, specific business turn over door for pressure differential space that says so.

Background

To meet certain requirements, it is often necessary to artificially create a pressure differential effect on adjacent spaces, and such pressure differential may be positive (internal pressure greater than external pressure) or negative (internal pressure less than external pressure). For example, the stadiums and amusement facilities with large air-mould structures adopt positive pressure, so that the air-mould structures are supported; the nucleic acid collection chamber for infectious diseases adopts positive pressure to prevent external polluted air from entering; nucleic acid detection rooms for infectious diseases, laboratories and the like use negative pressure to prevent the outflow of contaminated air from the inside. The technology of the differential pressure space has very wide application prospect.

The tightness of the individual spaces is particularly important in order to guarantee the effect of the pressure difference between adjacent spaces, which is mainly due to the design of the door. The door commonly used for facilities with pressure difference space is a revolving door, a two-way or multi-way sealing door, a double-layer zipper soft door, or a slit door for continuous air supply space. Revolving door and multichannel sealing door are generally used for the facility in fixed or semi-fixed place, and not only bulky, weight is heavy, and the installation is transported inconveniently, and the cost is high moreover, the junction need do sealed treatment. The double-layer zipper door is generally used for small temporary space and facilities, occupies a certain space and is inconvenient to enter. The slit door is mostly used for a dynamic pressure difference space for continuous gas supply and has the defects of large gas leakage, high energy consumption and the like.

Disclosure of Invention

The utility model provides a to prior art not enough, the utility model provides a be applied to business turn over door in pressure differential space, the door in this technique is convenient for transport the installation, has characteristics such as the cost is low, the leakproofness is good.

The technical scheme of the utility model:

the door comprises a door frame, an outer door and a door curtain, wherein the door frame, the outer door and the door curtain are all made of soft materials. The two outer doors are connected to the door frame, are identical in shape and are fixed on the door frame in a bilateral symmetry mode, and gaps are reserved between the two outer doors. The door curtain is positioned at one side of the two outer doors and covers the gap between the two outer doors, and the upper end of the door curtain is fixed at one side of the upper part of the door frame.

Further, the door frame is one of square, circular or oval.

Further, the door curtain is one of a square shape and an inverted trapezoid shape.

Further, the upper end of the door curtain is in one of an arc shape or a straight line shape, and the lower end of the door curtain is in one of an arc shape or a straight line shape.

Furthermore, the lower end of the door curtain is provided with a cylindrical through hole, and a sand bag is placed in the through hole.

Further, the door curtain is positioned on one side of the door with high pressure.

Further, the access door applied to the differential pressure space can be used singly or in combination of a plurality of doors.

Has the advantages that: the utility model provides a be applied to business turn over door in pressure differential space adopts the light yielding material installation of being convenient for transport. The pressure difference effect of outer door both sides to and the heavy object of door curtain lower extreme increase makes between door curtain and the outer door laminate more, improves the leakproofness of door.

Detailed Description

The invention is further described with reference to the following figures and examples.

Example (b): as shown in fig. 1 to 3, an access door applied to a differential pressure space includes a door frame 1, an outer door 2, an outer door 4, and a door curtain 5. Door frame 1, outer door 2, outer door 4, door curtain 5 all adopt transparent PVC surface fabric, connect outer door 2 and outer door 4 on the door frame 1, outer door 2 is unanimous with outer door 4 shape, and bilateral symmetry is fixed in on the door frame 1, leaves space 3 between outer door 2 and the outer door 4. The door curtain 5 is positioned at the inner sides of the

outer doors

2 and 4 and covers the gap 3 between the

outer doors

2 and 4, and the upper end of the door curtain 5 is fixed at the outer part of the upper end of the inner side of the door frame 1.

The doorframe 1 is round, and the door curtain 5 is square.

The upper end of the door curtain 5 is arc-shaped, and the lower end of the door curtain is also arc-shaped, so that the door curtain is convenient to be attached to a circular door frame.

The lower end of the door curtain 5 is provided with a cylindrical through hole 6, and a sand bag is placed in the through hole 6. The sandbag can increase the weight of the door curtain 5, and the door curtain 5 is more attached to the outer door 2 and the outer door 4 under the action of gravity.

The inner side pressure of the outer door 2 and the outer door 4 is higher than the outer side pressure of the outer door 2 and the outer door 4.

The access door applied to the pressure difference space is used singly or in combination according to the size of a use scene.

The entering and exiting method comprises the following steps: when people enter the door, the gap 3 between the outer door 2 and the outer door 4 is opened by hands, the door curtain 5 is pushed to enter the other side of the door, and because the pressure inside the outer door 2 and the pressure inside the outer door 4 are higher than the pressure outside the outer door 2 and the pressure outside the outer door 4, the door curtain 5 is quickly attached to the outer door 2 and the outer door 4 after people enter the door, and the sealing performance of the door is ensured. When the person who goes out, the hand lifts door curtain 5, takes off the space 3 between outer door 2 and the outer door 4, and when the person who goes out, door curtain 5 pastes on outer door 2 and outer door 4 rapidly, has guaranteed the leakproofness of door.

The access door applied to the pressure difference space can be applied to facilities with pressure difference environments, such as annular inflation channel amusement equipment (figure 4), membrane structure equipment (figure 5), a sealing laboratory and the like.

The above description is only an embodiment of the present invention, and the terms "left", "right", "inside", "outside", "up", "down" and the like are only used herein to describe a specific embodiment, but the technical features of the present invention are not limited thereto, and any person skilled in the art can make changes and modifications within the scope of the present invention.
