There is following problem in this structure: single axle is born the static load of whole air-valve valve block and dynamic load, is caused the stressed fatigue of axle risk of breakage to occur easily; Axle adopts welding manner to engage, cause easily weld seam aging, tired and perishable with valve block; The less ventilation section that single valve sheet butterfly structure forms in controlling device startup and pass closed procedure is long-pending to cause the pressure loss big, and the driving mechanism required torque is big; External bearings and mechanical seal have increased cost of goods manufactured and maintenance cost; Preparation process energy consumption height, easily produce pollutant, and production facility shortcoming such as have high input.
The model utility content
The utility model aims to provide simple, easy to maintenance, reliable, the efficient low-consume of a kind of making, the interior gas flow of ventilation duct that can be applied to multiple occasion is regulated the air-valve device, so that it is lighter with lower investment and maintenance cost the ventilation duct gas flow to be regulated.
It is as follows that the utility model solves the problems of the technologies described above the technological scheme that is adopted:
A kind of air quantity is regulated the air-valve device, the supporting base that comprises valve body and be arranged on valve outer wall, and valve block, and described valve inner is provided with a plurality of rotatingshafts, and described rotatingshaft passes described valve body; Described valve block integral body respectively passes described rotatingshaft center line cutting fluting place, and be fixed together with a plurality of rotatingshafts respectively by bolt, wherein, described rotatingshaft is linked together by connecting plate and continuous motion stem and driving mechanism, and described driving mechanism is installed in above the supporting base.
Further, preferred construction is that described driving mechanism controls transmission shaft by described connecting plate and continuous motion stem and valve block integral body is rotated in unidirectional 90 ° of scopes.
Further, preferred construction is that described valve block is three linkage structures.
Further, preferred construction is, also is provided with supporting sleeve and end socket fast, and it is coupled with described transmission shaft respectively.
Further, preferred construction is that described quick public attention inside is provided with seal ring.
Further, preferred construction is that described supporting sleeve and transmission shaft, valve body and valve block are made by glass fibre reinforced plastic material.
The utility model the stressed dispersion of its valve block, reduces the pressure loss and driving mechanism output torque after having taked technique scheme; And, by means of high strength, corrosion-resistant, heat-resistance type glass fibre reinforced plastic material, and then reduce the weight of product greatly, make and install easilyer to have better technical effect.
