Abstract
The utility model discloses an airtight explosion-proof door. The airtight explosion-proof door comprises a door frame and a door page, one side of which is hinged on the door frame. The door page is provided with a hand wheel which is connected with a buckle through a transmission assembly. The door page is an arc-shaped structure which is protruding outward. A plurality of reinforced ribs are arranged inside the door page. Flame retardant adhesive tapes are arranged at a connection of the door page and the door frame. The door page is provided with an explosion glass window which comprises a window frame installed on the door page through a pressure plate. The window frame is internally provided with layers of explosion glass. The flame retardant adhesive tapes are arranged at the connection of the explosion glass and the pressure plate and the door page. The airtight explosion-proof door is locked so that the door page, the door frame and the flame retardant adhesive tapes are adhered compactly so that the airtight explosion-proof door has airtight and explosion-proof performances. When explosion occurs, the arc-shaped surface out of the door page can unload and resist the shock wave of explosion. The flame retardant adhesive tapes between the door frame and the door page can resist high temperature at the moment of explosion and tolerate the explosion pressure of 0.45MPa.
Description
Technical field
The utility model relates to a kind of hermatic door, relates in particular to a kind of airtight explosion proof door mining or peculiar to vessel.
Background technology
Present technique is replenishing mine anti-explosion door, mining air tight door; It also is lifting to air tight door peculiar to vessel; Existing mining product does not have the complete standard of airtight explosion proof door, and marine product only has the low air tight door that requires and do not have the explosion proof door standard, has the shortcoming of function singleness, security reliability difference.
The utility model content
The purpose of the utility model is to provide a kind of airtight explosion proof door, and it has the characteristics of airtight, anti-blast pressure and the high temperature of anti-the instant of detonation, to solve the problem that mining or peculiar to vessel hermatic door exists in the prior art.
For reaching this purpose, the utility model adopts following technical scheme:
A kind of airtight explosion proof door; It comprises that a doorframe and a side are articulated in the door leaf on the doorframe; Be provided with handwheel on the said door leaf, said handwheel connects through transmission component pricks button, wherein; The inboard of said door leaf is provided with some reinforcing ribs, and the joint of said door leaf and doorframe is provided with flame-retardant rubber strip.
Especially, on the said door leaf implosion guard window is installed.
Especially, said door leaf is the arcuate structure that outwards protrudes.
Especially, said door leaf is hinged through hinge and doorframe.
Especially, said implosion guard window comprises through pressing plate and is installed on the window frame on the door leaf, and the several layers implosion guard is installed in the said window frame, and the joint of said implosion guard and pressing plate and door leaf is provided with flame-retardant rubber strip.
Especially, the number of plies that is provided with of said implosion guard is three layers.
The beneficial effect of the utility model is after compared with prior art said airtight explosion proof door rotation hand wheel drive bundle padlock is tight, to make door leaf; Doorframe and flame-retardant rubber strip fit tightly; Can possess airtight and explosion-proof performance, when blasting, door leaf outer arcuate surface can shed and resist the shock wave of blast; The flame-retardant rubber strip that is used between doorframe and door leaf can be resisted the high temperature of instant of detonation, can realize the blast pressure of anti-0.45MPa requirement.
