Experimental study of pneumatic single acting butterfly valve on offshore oil platform
This paper mainly describes the structural characteristics and working principle of the rack-and-pinion type single-acting butterfly valve,the design and calculation of the valve body components,the rotation Angle under the action of different numbers of springs and the results of the test method[1].Through reasonable design of valve body parts and selection of appropriate spring quantity and material,the valve can achieve excellent performance under different working conditions.Pneumatic single-acting butterfly valve is simple to operate,mainly composed of valve body,valve disc,valve stem,rack and pinion mechanism and pneumatic drive device,which is widely used in Bohai oil field.
