Abstract
This utility model relates to a kind of sealed door, particularly relates to a kind of steel structure double-leaf exhaust blower sealed door.Including doorframe, described doorframe is provided with left-hand door fan and right door leaf, between described left-hand door fan and doorframe, rotated by hinge page assembly respectively between right door leaf and doorframe, described left-hand door fan and right door leaf are that moving type opens and closes, and between described left-hand door fan and the top and the bottom of doorframe, are locked together by mechanism for opening/closing respectively between the top and the bottom of right door leaf and doorframe.Steel structure double-leaf exhaust blower air-tight door structure is compact, and good airproof performance is easy to operate.
Description
Technical field
This utility model relates to a kind of sealed door, particularly relates to a kind of steel structure double-leaf exhaust blower sealed door.
Background technology
The locking structure of sealed door of the prior art is relative complex, causes the inconvenience of operation, and properties is outstanding.
Chinese patent 201410040743.1, open a kind of plug-type airtight blast door of steel construction, including door leaf and scroll wheel, doorframe and the sealing joint strip of periphery, locking link gear, outside guide roller mechanism, trench cover plate raises device, and the steel guide rail for scroll wheel motion, door leaf both sides respectively set a set of inner side type leading wheel framework.Inner side type leading wheel framework coordinates locking link gear that the embedded pressing bar entirety that seals on door leaf is embedded or exited in the embedding groove of sealing joint strip, it is ensured that door leaf is opened smoothly.Manual traveling wheel mechanism guarantees light slip when opening of large scale door leaf.Little airtight blast door facilitates a small amount of personnel to come in and go out.This structure is relative complex, and using effect is general.
Utility model content
This utility model mainly solves the deficiencies in the prior art, it is provided that a kind of compact conformation, easy to operate, the steel structure double-leaf exhaust blower sealed door that sealing property is strong.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:
A kind of steel structure double-leaf exhaust blower sealed door, including doorframe, described doorframe is provided with left-hand door fan and right door leaf, between described left-hand door fan and doorframe, rotated by hinge page assembly respectively between right door leaf and doorframe, described left-hand door fan and right door leaf are that moving type opens and closes, and between described left-hand door fan and the top and the bottom of doorframe, are locked together by mechanism for opening/closing respectively between the top and the bottom of right door leaf and doorframe；
Described mechanism for opening/closing includes screw mandrel, the two side ends of described screw mandrel is respectively equipped with link assembly, described screw mandrel is rotated by worm reducer, described link assembly includes upper connecting rod and longitudinal lower link, in described longitudinal direction between the upper end of connecting rod and left-hand door fan, positioning by tapered end respectively between longitudinal lower link and left-hand door fan, described screw mandrel drives upper connecting rod and longitudinal direction lower link carry out displacement and plug fixing with doorframe；
Described left-hand door fan is respectively equipped with sealed valve in right door leaf, and described sealed valve is positioned with doorframe by valve detent mechanism, and described sealed valve passes through latch assembly and doorframe phase locking, is provided with exhaust fan in described sealed valve.
As preferably, in described longitudinal direction between connecting rod and screw mandrel, it is fixedly connected by pivoted arm respectively between longitudinal lower link and screw mandrel, described worm reducer is provided with handwheel.
In sealed door left and right door leaf steel structure girder compartment perforate, axial flow blower is installed, and sealed valve is installed in door leaf inboard row air port.Time just before a battle；Close left and right door leaf, open exhaust blower sealed valve and fix with positioner, start blower fan, get rid of technical interior carbon dioxide gas, before shock wave arrives；Close blower fan and sealed valve is converted to isolated type protection, stop radioactive contamination, biological warfare agent and chemical warfare agent to penetrate into technical interior.This equipment has airtight, air draft two function in the exhaust blower sealed door of one, i.e. shortens the building length in underground engineering air channel, causes valency reducing engineering.
Hinge page assembly, valve detent mechanism, latch assembly are respectively conventional structure.
Therefore, steel structure double-leaf exhaust blower sealed door of the present utility model, compact conformation, good airproof performance, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
