Description
Technical field
The utility model relates to engineering machinery, is specifically related to a kind of air-valve, and this air-valve is suitable for and small flow pipeline.
Background technique
This volume damper is indispensable tail end of central air conditioner accessory in the ventilation of industrial premises civil building, air conditioning and air purification engineering, generally be used in air-conditioning, in air system plumbing, be used for regulating the air quantity of arm, also can be used for new wind and regulate with mixing of return air.
In existing technology, air-valve is multiple leaflet constructs, regulates ventilation by the gradient of adjusting vane.And realize the cut-out of air-flow.This air-valve is applicable to the airduct of large discharge, and due to its complex structure, therefore its manufacture cost rises thereupon.So for small flow pipeline to need to find a kind of structure targetedly simpler.More practical air-valve.
Summary of the invention
The utility model provides a kind of air-valve of small flow air-flow, and this wind valve structure is simple, practical.
The utility model provides following technical proposals: small flow type pneumatic blast gate, comprise housing, blade, running shaft, the quantity of described blade is one, and the Internal periphery of the edge of described blade and described housing 1 matches, described running shaft is fixedly connected with in the center of described blade, the two ends of described running shaft are flexibly connected with the wallboard of described housing, wherein one end of described running shaft is provided with linkage mechanism, the input end motion of described linkage mechanism is straight line motion, and output terminal motion is angle rotary motion.
Further, described linkage mechanism comprises head rod, the second connecting rod, the 3rd connecting rod that top is flexibly connected successively, the input end of described linkage mechanism is provided with cylinder, the other end of described head rod is connected with described running shaft, and the described the other end of the 3rd connecting rod is connected with the mechanical actuating station of cylinder.
Further, the edge of described blade is provided with rubber weather strip, and the width of described rubber weather strip and the width of described blade and described housing match.
The utility model adopts technique scheme to have such beneficial effect, this pneumatic blast gate uses described air cylinder driven, coordinate song to stretch motion by described head rod, the second connecting rod, the 3rd connecting rod, described blade is completed and opens and closed action.The quantity of selected blade is only single, and structure is comparatively simple, is applicable to small flow, the airduct of small bore.Decrease manufacture cost to a certain extent.
