Description
Technical Field
The utility model relates to a wind valve blade, in particular to a wind valve blade capable of realizing low leakage.
Background
The air valve is often applied to places such as underground stations, tunnels and the like to play a role in fire prevention and wind prevention. The air valve is generally a switch type valve and is usually arranged on a pipeline of an air duct or a ventilation air conditioning system. The damper in the open state can maintain normal ventilation within the site where it is used. When an accident such as a fire occurs in the application place, the damper can be closed to control the spread of the accident such as the fire. The air valve is usually used in an environment with higher temperature and larger pressure difference. In order to meet the operational environment of the damper, the blades in the damper need to have sufficient strength and rigidity. And when the air valve is in a closed state, two adjacent air valve blades need to realize fastening and reliable sealing connection.
