Problems solved by technology

Utility model patent CN201344718Y discloses a high-temperature-resistant and corrosion-resistant concrete air duct, but the utility model patent relates to a "high-temperature-resistant and corrosion-resistant concrete air duct applied in the main kiln wall of the tunnel kiln in the building materials industry", It should be said that this prior art is not suitable for residential smoke exhaust systems
It is obviously difficult to effectively prevent the spread of fire by relying solely on the force of the blades to hang freely in the existing check valves. A small number of check valves are equipped with tension springs, but manual control is required, and it is difficult to prevent the spread of fire in a timely and effective manner.
The contact surface between the existing check valve and the wall lacks the necessary sealing device, which also greatly affects the effect of the check valve on preventing the spread of fire

Abstract

The invention provides a glue gas discharge subsystem of a residential flue gas emission system. The flue gas discharge subsystem of the residential flue gas emission system comprises a combined cast-in-place roof preformed hole, a combined connection sleeve and an inertia wind-proof cap. The wind-proof cap is provided with a supporting cylinder with one end located on the roof of a building, a wind-proof cylinder located on the radial outer side of the other end of the supporting cylinder and a wind-proof shield assembly arranged in the wind-proof cylinder. An air duct installation assembly is arranged at the connection position between an exhaust pipeline of the subsystem and the floor slab of the building. The installation assembly comprises a connection sleeve pipe and a connection sleeve plate, wherein the diameters of the two ends of the connection sleeve pipe are identical with the inner diameter of the floor slab preformed hole, the middle portion of the connection sleeve pipeis provided with a square outside and a circular inside, and the connection sleeve plate is provided with a square outside and an circular inside. The inner diameter of the circle of the sleeve platewhich is provided with the square outside and the circular inside is equal to the outer diameter of the connection sleeve pipe.

Description

technical field [0001] The invention relates to a gas discharge system, in particular to a smoke output subsystem of a residential smoke discharge system. Background technique [0002] With the rapid development of urbanization and the continuous improvement of people's living standards, higher requirements are put forward for living conditions and living environment. New houses must ensure that the exhaust gas in houses such as kitchens and bathrooms in the houses will not cause environmental pollution. Existing residential flue gas discharge system generally comprises the horizontal exhaust input duct of every household in the dwelling house, the output part of vertical conveying duct and roof part. However, the prior art discloses the materials of each part of the flue gas system. For example, the CN2436798Y utility model patent discloses a vertical smoke exhaust duct for residential kitchens and bathroom detachable check valves, and also discloses vertical The technical...
