Abstract

The invention provides a cold and hot air hose valve good in airtightness and adapting to the cold and hot environment. The cold and hot air hose valve good in airtightness aims to overcome the defects that the air leakage is large after an existing air hose valve is closed and potential safety hazards exist. The cold and hot air hose valve comprises a valve body, blades, blade shafts, an executing mechanism, a temperature sensor and connection rods. The blade shafts are fixed into the valve body. The blades are matched with the blade shafts. The blades are driven by the blade shafts to rotate. The blades are controlled by the executing mechanism to be opened and closed. The temperature sensor is fixed to the valve body. The cold and hot air hose valve further comprises reeds. One ends of the reeds are fixed to the blades. The other ends of the reeds abut against the surfaces of the adjacent blades. Compared with the prior art, the cold and hot air hose valve has the beneficial effects of being good in airtightness, and the air leakage meets the fire fighting requirement.

Description

technical field [0001] The invention relates to the technical field of air duct valves, in particular to a hot and cold air duct valve with good sealing performance and adaptable to hot and cold environments. Background technique [0002] Air duct valves, especially those with fire protection function, are commonly used in modern buildings. They are installed in large quantities on the air supply and return air ducts of ventilation and air conditioning systems. They are normally open. When the ambient temperature is abnormal due to maintenance or fire It can be closed to block air circulation and play the role of blocking smoke and fire. At present, the air duct valves on the market have gaps between the blades and between the blades and the bars after closing, and the sealing performance is not good. The air duct valves with fire protection function have a large amount of air leakage after closing, which cannot meet the fire protection requirements. There are security risk...
