Preset angle control method for flue check valve of high-rise building

Abstract

The invention provides a preset angle control method for a flue check valve of a high-rise building. The preset angle control method comprises range hoods mounted on different floors, an air outlet ofeach range hood communicates with a public flue through a respective smoke pipe, a check valve plate is mounted in each smoke pipe, a flue fan is mounted in the public flue, the range hoods are provided with fans, and the range hoods are provided with intelligent valve sockets capable of detecting the total power of the range hoods. The preset angle control method for the flue check valve of thehigh-rise building has the advantages that the input power of an indoor machine is detected by utilizing intelligent valve bodies of different floors, self-adaptive installation and adjustment are achieved through a method of comparing power and adjusting valve plate feedback, angle adjustment before installation can be easily completed by recording the current adjusting angle; the angles of the valve plates are automatically sorted and adaptively adjusted according to mounting positions and flues instead of preset values, and automatically reconstructing a plurality of valve plate angle schemes can be carried out according to current lowest startup floor information.

Description

technical field [0001] The invention relates to a central flue system, in particular to a method for controlling a preset angle of a flue check valve in a high-rise building. Background technique [0002] At present, the floors of newly-built buildings in cities are generally higher and higher. Since the outlets of high-rise public flues are generally set on the top of the floors, the switching status of the range hoods of each user's home will affect the resistance of the system outlet, making the smoke exhaust situation of users at the bottom poor. . In recent years, the user-side adjustable angle valve combined with the centralized filtration and discharge of the main fan at the flue outlet on the roof has begun to be applied in some well-decorated buildings. The main fan on the roof performs frequency conversion + valve preset angle to achieve flow distribution for users with different operating rates. , to a certain extent, it can solve the poor smoke exhaust situation...

Problems solved by technology

For range hoods of the same brand as the valve body and central machine, the P-Q-W curve can be measured in advance, but for other brands of range hoods, its performance curve is often not known in advance
