         在生产过程中，为了使介质的压力、流量等参数符合气动控制阀工艺流程的要求，需要安装调节机构对上述参数进行调节。调节机构的主要工作原理，气动蝶阀是靠改变阀门阀瓣与阀瓣与阀座间的流通面积，达到调节上述参数的目的。属于电动调节阀这类阀门的统称为控制阀，其中分为依靠介质本身动力驱动的称为自驱式控制阀如减压阀、气动闸阀稳压阀等，凡领先上来动力驱动的（如电力 、压缩空气和液动力）气动球阀称为他驱式控制阀，如电动调节阀、气动调节阀和液动调节阀等。

         I n the production process, in order to make the medium pressure, flow and other parameters meet the process requirements,Multi-stage pumps need to install the adjusting mechanism to adjust these parameters. Adjusting mechanism and the operating principle, is by changing the valveSweage pumps &Sludge pumps disc and valve seat between the valve and the flow area to achieve the purpose of adjusting Slurry pumpsthe above parameters. Such valves are referred to asPneumatic and electric diaphragm pumps control valves, which are divided into power-driven dependent media itself is called self-drive Other pumpscontrol valve such as valve, regulator valve, all leading up power-driven (such as electricity, compressed air and fluid power) as his driving style control valves, such as the electric control valve, pneumatic control valve and hydraulic control valve.
