进口先导活塞式气体减压阀(德国OLES阀门)
【进口先导活塞式气体减压阀】详细说明:
先导活塞式气体减压阀属于先导活塞式减压阀。由主阀和导阀两部分组成。主阀主要由阀座、主阀盘、活塞、弹簧等零件组成。导阀主要由阀座、阀瓣、膜片、弹簧、调节弹簧等零件组成。通过调节调节弹簧压力设定出口压力、利用膜片传感出口压力变化,通过导阀启闭驱动活塞调节主阀节流部位过流面积的大小,实现减压稳压功能。先导活塞式气体减压阀主要用于气体管路,如空气、氮气、氧气、氢气、液化气、天然气等气体。
The pilot piston type gas pressure reducing valve belongs to the pilot piston type pressure reducing valve. It consists of main valve and pilot valve. The main valve is mainly composed of seat, main disc, piston, spring and other parts. The guide valve is mainly composed of seat, disc, diaphragm, spring, adjusting spring and other parts. The outlet pressure is set by adjusting the spring pressure, the diaphragm is used to sense the outlet pressure change, and the pilot valve opens and closes to drive the piston to adjust the flow area of the throttle part of the main valve, so as to realize the function of reducing pressure and stabilizing pressure. Pilot piston gas pressure relief valve is mainly used in gas pipelines, such as air, nitrogen, oxygen, hydrogen, liquefied gas, natural gas and other gases.
【进口先导活塞式气体减压阀】特性:
减压阀是通过调节,将进口压力减至某一需要的出口压力,并依靠介质本身的能量,使出口压力自动保持稳定的阀门。减压阀的作用原理是靠阀内流道对水流的局部阻力降低水压,水压降的范围由连接阀瓣的薄膜或活塞两侧的进出口水压自调节。管道上如一次减压不够可采取二次减压;减压系统通常需采取一备一用,防止因现用减压阀故障而破坏系统或下游设备。
直接作用减压阀:利用出口压力变化,直接控制阀瓣运动的减压阀。
先导式减压阀:由主阀和导阀组成,出口压力的变化通过放大来控制主阀动作的减压阀。
薄膜式减压阀:采用膜片作为敏感原件来带动阀瓣运动的减压阀。
活塞式减压阀:采用活塞作为敏感原件来带动阀瓣运动的减压阀。
