进口可调式蒸汽减压阀(德国OLES奥莱斯)
【进口可调式蒸汽减压阀】详细说明：
减压阀，可用于蒸汽、压缩空气及其它气体的压力控制。下游压力经由内部或外部的压力感应管反馈至压力导阀，由主阀隔膜操作，调节主阀的开度。即使在上游压力和蒸汽负载变化时，仍可准确的控制下游压力。为了适应不同的需要，减压阀的阀体采用了不同的材质，分别为球墨铸铁、铸钢和不锈钢。对不同型号的阀，内部组件采用统一的不锈钢材质，以方便维修保养和更换。
Pressure relief valve can be used for pressure control of steam, compressed air and other gases. The downstream pressure is fed back to the pressure guide valve through the internal or external pressure induction tube, which is operated by the main valve diaphragm to adjust the opening of the main valve. Even when the upstream pressure and steam load change, the downstream pressure can be accurately controlled. In order to meet different needs, the valve body of pressure relief valve adopts different materials, namely ductile iron, cast steel and stainless steel. For different types of valves, the internal components are made of uniform stainless steel to facilitate maintenance and replacement.
【进口可调式蒸汽减压阀】结构特点：
内螺纹连接先导活塞式蒸汽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、缸套、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。
本产品主要用于蒸汽管路，起减压稳压作用。
The internal thread connection pilot piston type steam 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, cylinder liner, 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 is used to open and close the driving piston to adjust the size of the throttle area of the main valve so as to realize the function of reducing pressure and stabilizing pressure.
This product is mainly used in steam pipeline, which can reduce pressure and stabilize pressure.
【进口可调式蒸汽减压阀】工作原理：
1，本阀由阀体、波纹管组件、阀座、调节弹簧等组成，波纹管组件的阀杆和阀体相配合待波纹管受到介质压力后，推动阀杆移位，改变密封面与阀座间的距离。
2，本阀出厂时，密封面与阀座是关闭的，需要使用时，通过顺时针方向旋转螺丝，使调节弹簧压向阀杆，顶开密封面。当受到介质压力时，介质分二路，一路由阀体至出口，另一路由阀体上的平衡孔到波纹管的内腔，并使阀杆向上和调节弹簧力的平衡。当进口压力增加时，波纹管组件的阀杆向上移位，密封面和阀座之间的间隙减小，当调节弹簧和波纹管的力平衡时，则出口处的压力就稳定在需要值上，当进口压力减小时则反向移动，仍使出口压力稳定在需要值上。
