Description
Technical field
The utility model relates to a kind of door, particularly relates to a kind of airtight door.
Background technology
Usually hermatic door to all be used in places such as biology laboratory, pharmacy or medical toilet, nuclear power stations, current most of hermatic door adopts mechanical seal structure, its tightness is not good enough, and therefore, the hermatic door researching and developing a kind of high-air-tightness becomes those skilled in the art's problem demanding prompt solution.
Summary of the invention
The utility model is to solve above-mentioned deficiency, provides a kind of airtight door.
Above-mentioned purpose of the present utility model is realized by following technical scheme: a kind of airtight door, comprise doorframe and door leaf, described door leaf is connected with doorframe by hinge, door leaf is provided with handle and form, it is characterized in that: described doorframe top is provided with controller, it is shiny surface inside described doorframe, groove is provided with inside described door leaf, described groove is provided with mechanical seal bar and gas-flow closure bar, described gas-flow closure bar is connected with tracheae, tracheae connects air valve switch, air valve switch connection control device, controller is provided with extraneous gas access port and external power source access port, and connect air tight door switch and emergency stop switch.
Further, described gas-flow closure bar is made up of silicon rubber, and silicon rubber has more flexibility compared with common silica gel weather strip, has more acid-resisting compared with General Purpose Rubber.Silicon rubber has the performances such as excellent heat resistance, cold resistance, dielectricity, resistance to ozone and resistance to atmospheric aging, can at-60 DEG C (or lower temperature) to+250 DEG C (or higher temperature) Long-Time Service.It has excellent physiological inertia, nontoxic, tasteless, corrosion-free, anticoagulation, good with the compatibility of body, can stand harsh conditions for sterilization.So it is fit closely for being used in toilet.
Further, described hinge is made up of 304 stainless steels, and succinct profile meets clean needs, and described hinge thickness is 4.0mm, ensure that the intensity of hinge.
Further, the thickness of described doorframe is 50mm, 75mm or 100mm; The thickness of described door leaf is 50mm, 75mm or 100mm.
Further, described doorframe and door leaf are made up of 304 stainless steels or galvanized sheet plastic-blasting.
Further, described doorframe is provided with emergency stop switch, cuts off the electricity supply under emergency conditions and gas circuit, ensures that personage passes through.
Further, described form is circular or square.
The utility model advantage is compared with prior art: employing be double-channel sealing structure, around doorframe, two seals bar is set with door leaf contact site, " returning " font closed cavity is formed when door is closed, be gas-flow closure together, be mechanical seal together, two seals bar more ensure that the tightness of door.
Accompanying drawing explanation
Fig. 1 is the outboard structure schematic diagram of the utility model embodiment.
Fig. 2 is the inside structure schematic diagram of the utility model embodiment.
Fig. 3 is the structural representation of the utility model embodiment door leaf open mode.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of airtight door, comprise doorframe 1 and door leaf 2, described door leaf 2 is connected with doorframe 1 by hinge 3, door leaf 2 is provided with handle 4 and form 5, it is characterized in that: described doorframe 1 top is provided with controller 12, be shiny surface 6 inside described doorframe 1, groove 7 is provided with inside described door leaf 2, described groove 7 is provided with mechanical seal bar 8 and gas-flow closure bar 9, described gas-flow closure bar 9 is connected with tracheae 10, tracheae 10 connects air valve switch 11, air valve switch 11 connection control device 12, controller 12 is provided with extraneous gas access port 13 and external power source access port 14, and connect air tight door switch 15 and emergency stop switch 16.
Further, described gas-flow closure bar 9 is made up of silicon rubber; Described hinge 3 is made up of 304 stainless steels; The thickness of described doorframe 1 is 50mm, 75mm or 100mm; The thickness of described door leaf 2 is 50mm, 75mm or 100mm; Described doorframe 1 and door leaf 2 are made up of 304 stainless steels or galvanized sheet plastic-blasting; Described doorframe 1 is provided with emergency stop switch 16, cuts off the electricity supply under emergency conditions and gas circuit, ensures that personage passes through; Described form 5 is circular or square.
The utility model can be double sealing, is mechanical seal together, is gas-flow closure together, also only can establishes one gas-flow closure bar.When the utility model runs, gas-flow closure bar, by dilating principle, makes door leaf 2 and doorframe 1 seal completely, by pressure measured value, when bearing <1500pa, almost without leakage.In addition, after doorframe 1 can being increased above, control system is contained in the inside, complete isolating inner air and outer air, ensures gas not convection current.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model manual and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
