Abstract
The utility model provides a seal diaphragm for inciting somebody to action door frame of sealed door carries out sealing connection which characterized in that: seal diaphragm (1) and make by the airtight flexible material that can bear gas pressure, have a closed end (11) and open end (12), closed end (11) sealing connection has admission valve (3) and manometer (2), the edge all around of open end (12) is equipped with sealed fill up (13). This closed diaphragm (1) can substitute rigid material and door leaf and door frame component atmospheric pressure chamber, because airtight flexible material light in weight, collapsible, the convenient carries, brings very big convenience for on -the -spot sealed door experiment.
Description
Technical field
This utility model relates to engineering and engineering test field, particularly relates to a kind of closing diaphragm for being connected and sealed by the doorframe of sealed door.
Background technology
Sealed door is widely used in the oral area in the fields such as chemical industry, people's air defense, boats and ships, Aero-Space, its effect includes completely cutting off gas, liquid, guarantee personnel and equipment safety, at chemical field, sealed door is used for blocking harmful gas, and in civil air defense constructions and installations field, sealed door blocks shock wave, poison, early nuclear radiation for wartime, at aircraft, boats and ships, submarine, space industry, sealed door is used for completely cutting off pressed gas, liquid.
Sealed door needs before dispatching from the factory, on testing equipment, sealed door sample is carried out air-tight test, doorframe is closed with rigid material corresponding with doorframe size and shape during test, door leaf, doorframe and rigid material is made to constitute the pressure chamber of test, by being filled with compressed gas to pressure chamber, check the air-tightness between doorframe and door leaf.Chinese Patent Application No. 201310404383.4 discloses a kind of defense equipment detection platform and the patent of invention of air-tightness detection method, specifically disclose and doorframe bolt and the pressing plate of measured defense equipment are fixed with superpressure room (being equivalent to additional steel plate), seal with glass cement between doorframe and superpressure room.Owing to sealed door is the passage passed through for personnel, goods and materials, the cross dimensions of door is relatively big, and in civil air defense constructions and installations, door leaf width reaches more than 5 meters, highly reaches more than 3 meters, and its rigid material is bulky, heavy, installs and manufacturing cost is higher.In addition, the air-tightness typically requiring the sealed door good to in-site installation in engineering is sampled detection, use rigid material to close doorframe and be sampled detection, owing to rigid material is bulky, heavy, being transported, carry, install and bring the biggest potential safety hazard, the occasion rigid material running into passage narrow and small cannot pass through at all.
Utility model content
For solving prior art problem, this utility model provides a kind of closing diaphragm for being connected and sealed by the doorframe of sealed door conveniently transporting, carrying.
This utility model be the technical scheme is that closing diaphragm is made up of the airtight flexible material that can bear gas pressure, has a Guan Bi end and an opening, and Guan Bi end is sealedly connected with intake valve and Pressure gauge, and the edge of opening is provided with sealing gasket.
Described airtight flexible material is rubber, epithelium or non-woven fabrics.
Intake valve is tyre valve core or analog structure.
Sealing gasket is rubber gasket, is tightly connected with the two sides closing diaphragm by the way of bonding or hot fusion.
Opening is corresponding with doorframe shapes and sizes to be closed.
It is made up of the airtight flexible material that can bear gas pressure owing to closing diaphragm, there is a Guan Bi end and an opening, Guan Bi end is sealedly connected with intake valve and Pressure gauge, the edge of opening is provided with sealing gasket, this closing diaphragm can substitute rigid material and constitute atmospheric pressure cavity with door leaf and doorframe, owing to airtight flexible material is lightweight, collapsible, carry easily, bring great convenience to on-the-spot sealed door test.
Accompanying drawing explanation
Accompanying drawing described herein is used for providing being further appreciated by of the present utility model, constitutes the part of the application, and schematic description and description of the present utility model is used for explaining this utility model, is not intended that improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the schematic diagram of the closing membrane chip architecture of this utility model embodiment；
Fig. 2 is Fig. 1 side view schematic diagram；And
Fig. 3 is partial enlargement structural representation in Fig. 1.
Detailed description of the invention
Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
See accompanying drawing 1,2 and accompanying drawing 3, a kind of closing diaphragm for the doorframe of sealed door is connected and sealed of this utility model embodiment, it is made up of the airtight flexible material that can bear gas pressure, this closing diaphragm 1 has a Guan Bi end 11 and an opening 12, Guan Bi end close 11 is sealedly connected with intake valve 3 and Pressure gauge 2, and the edge of opening 12 is provided with sealing gasket 13.
Wherein, airtight flexible material includes that rubber, epithelium and non-woven fabrics are made.Intake valve 3 preferentially uses tyre valve core or the analog structure with inlet, outlet function.Sealing gasket 13 is rubber gasket, is tightly connected with the two sides closing diaphragm 1 by the way of bonding or hot fusion.Opening 12 is rectangular shape, and its size adapts with the rectangle doorframe closed, and deforms as one, and opening 12 can also be toroidal, adapts with annular doorframe shape to be closed.
Can be seen that from the above description, it is made up of the airtight flexible material that can bear gas pressure owing to closing diaphragm 1, there is a Guan Bi end 11 and an opening 12, Guan Bi end 11 is sealedly connected with intake valve 3 and Pressure gauge 2, and the edge of opening 12 is provided with sealing gasket 13, and this closing diaphragm 1 can substitute rigid material and constitute atmospheric pressure cavity with door leaf and doorframe, owing to airtight flexible material is lightweight, collapsible, carry easily, bring great convenience to on-the-spot sealed door test.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
