Description
Technical field
The utility model relates to the air discharging structure of house, particularly relates to a kind of novel ladder combined type variable-pressure fire-proof exhaust passage system.
Background technology
At present, extra-high-speed layer gas flue is oversize, production difficulty, and inconvenience transport is installed.Fume centralized is emitted in a smoke pipe, the excessive mutual mineralization pressure of flue gas flow.Cause exhaust not smooth, alter cigarette, alter taste.
Summary of the invention
For the above-mentioned shortcoming of the prior art of mentioning, the utility model provides a kind of novel ladder combined type variable-pressure fire-proof exhaust passage system, and it,, by special structure and material design, addresses the above problem.It is characterized in that:
Comprise exhaust duct, support structural member, transformation sleeve pipe, from water conservancy diversion anti-fire check valve, unpowered wind-proof cap;
Described support structural member is installed and is watered in every floor face;
Described exhaust duct uses described transformation sleeve pipe at described support structural member place, upper and lower exhaust duct to be connected;
Describedly be installed on described smoke vent exhaust ports from water conservancy diversion anti-fire check valve;
Described unpowered wind-proof cap is installed on described exhaust duct top.
Preferably, described exhaust passage system is made up of two exhaust ducts, and 30 layers connect to roof from bottom for Article 1 exhaust duct below, and Article 2 exhaust duct is 30 layers and up connects to roof.
Preferably, described wind-proof cap is that circular metal steel plate is made.
Preferably, described support structural member can be A type angle bar support structural member or pre-buried waterproof support mouthpiece or the pre-buried waterproof support of Type B mouthpiece.
Preferably, described is that employing anti-corrosion metal material and stainless steel materials are molded and shaped from water conservancy diversion anti-fire check valve.
The beneficial effects of the utility model are:
The utility model adopts staging pack with two different size exhaust duct matched combined of gas distribution form.Single-unit exhaust duct specification is little, lightweight, is convenient to production and transport and installs, and reduces whole work progress cost, and the single-unit exhaust duct specification that efficiently solves a composition is large, deadweight is not easy to greatly the problems such as production, transport, installation.Article two, different size exhaust duct matched combined allows the flue gas shunting discharge of different floors, does not form mutually blowdown presssure, reaches not alter cigarette, do not flow backwards the effect of exhaust duct smoothness.
The utility model adopts cement prefab support structural member.Every floor face is installed the support structure joint of pouring same size, exhaust duct is arranged in support structural member and is connected, every floor face can be installed arbitrarily different floor exhaust ducts after pouring support structural member is installed, the weight bearing of exhaust duct is on each floor, can, to any floor maintenance, the dismounting of exhaust duct are installed, concrete prefabricated support structure joint be watered and is filled on flooring.The safety problem of the weight bearing that can effectively solve exhaust duct on exhaust duct; Solve original exhaust duct the problem that can only install is from below to up installed; Can not be again after solving exhaust duct and installing the problem such as repair demolition arbitrarily.
When adopting exhaust duct to install, native system after interface installation transformation sleeve pipe connects upper and lower exhaust duct, can effectively prevent that exhaust duct interface from leaking cigarette, altering taste.Can produce transformer action to the flue gas of discharge at exhaust duct two ends interface, form and pull out airway dysfunction.Diaphragm valve is installed in the utility model exhaust duct and can be made the flue gas of discharge by designing requirement upwards water conservancy diversion discharge in exhaust duct, discharge does not cause problems such as altering cigarette downwards.
Wind-proof cap of the present utility model adopts metal foil to make, and wind-proof cap is circular design.The peripheral board that keeps out the wind of wind-proof cap is higher than built-in exhaust opening, and the flue gas of exhaust duct discharge can block blast by the peripheral board that keeps out the wind of wind-proof cap, makes it not be subject to influenced by wind pressure, reaches the smooth and easy effect of exhaust.
Variable cross-section exhaust duct exhaust system of the present invention, coupling system exhaust equivalent progressive law, by variable cross-section optimal design, reaches exhaust duct internal gas pressure even, and exhaust steady and smooth reduces and takies kitchen guarding space simultaneously.Prevent upper and lower floor fire spread; Prevent that in exhaust passage system, gas pours in down a chimney; Prevent that rain, snow, outdoor wind-fall are poured in exhaust passage system.Ladder combined type variable-pressure fireproof exhaust passage is practically applicable to various floor heights, gas flue at special super-high buildings more than 30 layers divides two installations, allow the flue gas shunting of exhaust duct, it while reaching exhaust smoke evacuation, is the effect that stream is dredged in exhaust duct decompression, efficiently solve special High-rise Building Design gas flue oversize simultaneously, production difficulty, the difficult problem that inconvenience is installed.
