Background
According to the requirement of technical Standard of building Smoke prevention and Smoke evacuation System GB51251, in a place where mechanical smoke evacuation is needed to be arranged in a building, when the smoke evacuation quantity is not more than 6m and no natural smoke evacuation condition exists, the smoke evacuation quantity is not less than 60m3/(h.m2) Calculating, and taking value of no less than 15000m3H is used as the reference value. When the smoke exhaust system is designed, the indoor clear height is controlled to be less than 6m and the division area of a single smoke-proof subarea is controlled not to exceed 250m2Thus, the smoke discharge of each smoke-proof subarea can be 15000m3H, which also creates conditions for modular design of the smoke evacuation tip device. The existing design standard of smoke prevention and exhaust is to limit the smoke discharge amount of a single smoke outlet according to the smoke layer thickness under the smoke outlet, therefore, the smoke outlet of the existing smoke exhaust device is usually arranged on the top surface of a smoke exhaust air pipe during design so as to increase the smoke layer thickness under the smoke outlet, thereby increasing the smoke discharge amount of the single smoke outlet; but when the fire control system of discharging fume design, often can't confirm specific furred ceiling form, this just leads to constantly adjusting fume extractor, wastes time and energy, and the construction is inconvenient and with high costs, consequently, needs a fume extractor that has high flexibility urgently.
SUMMERY OF THE UTILITY MODEL
To exist not enough among the prior art, the utility model provides a fire control end device that discharges fume can select corresponding open position that discharges fume according to the furred ceiling form, and need not redesign installation end device, and it is nimble more convenient to use, and labour saving and time saving can also help saving the cost.
The utility model discloses a realize above-mentioned technical purpose through following technological means.
A fire-fighting smoke-discharging end device comprises a smoke-discharging fire-proof valve, wherein the smoke-discharging fire-proof valve is connected with a smoke-discharging valve flange, the other end of the smoke-discharging valve is connected with a fire-proof air pipe flange, and the other end of the fire-proof air pipe is provided with a first blind plate; smoke exhaust openings are preset at the top, the bottom, the front part and the rear part of the fireproof air pipe, and flange connectors are installed at the smoke exhaust openings; the smoke exhaust fire prevention valve and the smoke exhaust valve are in signal connection with the control cabinet.
Furthermore, the smoke exhaust opening is provided with a second blind plate through a flange interface.
Furthermore, high temperature resistant grids are installed at the smoke exhaust opening through flange interfaces.
Furthermore, the smoke exhaust opening is provided with a soft air pipe through a flange connector.
Furthermore, at least one smoke exhaust opening is preset in the top, the bottom, the front part and the rear part of the fireproof air pipe.
Further, the fireproof air pipe is made of a material with the fire resistance limit not lower than 1.00 h.
The utility model discloses following beneficial effect has:
the utility model provides a fire control end device that discharges fume all presets the opening of discharging fume in four directions at fire prevention tuber pipe top, bottom, front portion, rear portion, and constructor can be according to specific furred ceiling design, more changes the second blind plate on the opening of discharging fume corresponding position for high temperature resistant grid or soft tuber pipe in a flexible way, realizes discharging fume, and need not redesign installation end device, helps saving the cost, so both made things convenient for the design and construction, the material resources of using manpower sparingly can guarantee the effect that the fire control was discharged fume again.
