So, using the mode of blocking crack between a door and its frame, prevent smog from entering into indoor, Smoke prevention is effective.
As optimization, described crack between a door and its frame blocking device includes that a circle of door body peripheral position can absorb water and force the water expander of outward expansion to constitute stifled bar after meeting water, also include constituting controlling organization with the inlet channel of switch valve, inlet channel water inlet end is for connecting with fire extinguisher canvas hose, and inlet channel water side and water expander connect.
So, when running into fire incident, control switch valve and inlet channel is opened, outward expansion being blocked by crack between a door and its frame after water inlet water supply expander adhesive, plays good isolation Smoke prevention effect and simple in construction, is beneficial to implement.
As optimization, inlet channel water side is connected and installed with the feed pipe that a circle is embedded in water expander, and on feed pipe, uniform intervals is provided with apopore.
So, it is ensured that water expander outward expansion effect is relatively reliable and uniform.
As optimization, water expander outer ledge is provided with groove, and described feed pipe is embedded in groove and apopore is positioned at bottom portion of groove.So, burying underground and water outlet of feed pipe is facilitated.
As optimization, described inlet channel is bellows and one end is fixed in door body, the other end for and be embedded in the fire extinguisher canvas hose of body of wall and connect.So, the installation facilitating inlet channel makes it not rotated by door body switch to be affected.Preferably select to be that the corrugated conduit one end that is connected with door body is positioned at door body lower surface near position, rotating shaft side.
As optimization, described switch valve is magnetic valve, and door body is additionally provided with mist detecting device, and mist detecting device is connected in solenoid valve control circuit and realizes automatically control electromagnetic valve switch.
In this manner it is achieved that smog controls switch valve after automatically detecting judgement open water supply startup.
As optimization, magnetic valve is installed in door body, and is positioned in the door body of magnetic valve side and offers maintenance side door.
So, the installation of convenient electromagnetic valve and maintenance.
As optimization, mist detecting device is positioned at door body top 1/3rd altitude range.
So, facilitate flue gas reach degree of danger still cannot safe escape at a puss, just can open switch valve and control to block door, when flue gas is less, the door body locking that will not cause because of the bulbs of pressure of expander, beneficially personnel escape.
As optimization, door body periphery surface being provided with the mounting groove of a circle outward opening, water expander is arranged in mounting groove.
So, facilitate the setting of water expander and retrain its expansion direction for outwards to be beneficial to block crack between a door and its frame.
As optimization, outside mounting groove, also paste the moistureproof pad pasting being provided with a circle for shield water expander.The most attractive in appearance and the most moistureproof.
As optimization, water expander is that hydro-expansive rubber is made.The most with low cost and expansion effect is good.
In sum, the utility model has a simple in construction, convenient uses, and easily transforms existing smoke-stop door structure, and Smoke prevention is effective, when flue gas is less, and the advantage such as the door body locking that will not cause because of the bulbs of pressure of expander, beneficially personnel escape.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Fig. 3 is the connection diagram of water inlet pipe of the present utility model.
