Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment:A kind of staircase malleation value control structure, as shown in figure 1, including staircase passage 1, being built in actual
Building the pressure value of general staircase in thing should be maintained in the range of 40Pa ~ 50Pa, occur fire or other burst feelings
When condition, it can effectively ensure that escape personnel can quickly open passway for escaping door, while access door is opened
Smog, which can effectively be reduced, can rapidly enter inside staircase and influence safe escape, in prior art, staircase
Malleation is not controlled well, often occurs that the malleation of staircase is excessive, is caused the door of staircase and can not quickly be opened, and
Certain resistance is produced to escape personnel, so as to occur to safe escape adverse conditions.
There is the excessive situation of malleation value to effectively reduce staircase, so being provided with row pressure in staircase passage 1
Device 6, pressure discharge device 6 is forced draft machine, forced draft machine can by the normal pressure in staircase by the form of blast from
The outside of staircase passage 1 is discharged at outlet 2 on side wall, the discharge of pressure in staircase passage 1 is quickly realized;In order to protect
The normal pressure demonstrate,proved in staircase passage 1 is stable in normal scope, and timely pressure can be entered when going beyond the scope
Row discharge work, so the equipment provided with detection pressure is needed inside staircase passage 1, so in staircase passage 1 also
