【进口可调式膜片式减压阀】详细说明:
隔膜可调式减压稳压阀是安装于高层建筑给排水系统管道上,将进口压力臧至某一需要的出口压力的特种阀门。隔膜式可调减压阀依靠本身能量使出口压力保持稳定在设定值,即出口压力不因进口压力及流量的变化而变化并且阀门控制系统的进口处装有一个自清洁滤网,利用流体特性,使比重较大、直径较大的悬浮颗粒不会进入控制系统.确保系统循环畅通无阻,使阀门能安全可靠地运行。系统动作灵敏,使用寿命长。
Diaphragm adjustable pressure reducing and stabilizing valve is a special valve which is installed in the water supply and drainage system of high-rise buildings, and it can evaluate the import pressure to a certain required outlet pressure. Diaphragm-type adjustable pressure relief valve relies on its own energy to keep the outlet pressure stable at the set value, that is, the outlet pressure does not change with the change of inlet pressure and flow rate, and a self-cleaning filter is installed at the inlet of the valve control system. By utilizing the fluid characteristics, the suspended particles with larger specific gravity and diameter will not enter the control system. To ensure the smooth circulation of the system, so that the valve can operate safely and reliably. The system operates sensitively and has a long service life.
【进口可调式膜片式减压阀】结构特点:
本系列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。
This series of pressure relief valves belong to pilot piston type pressure relief valves. 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.
【进口可调式膜片式减压阀】性能:
可调式减压稳压阀减小较高的上游压力并产生一个稳定的较低的下游压力,不受上游压力或流量变化的影响。 可调式减压稳压阀既可减动压又可减静压. 阀门下游压力可依据系统要求在一定范围内连续可调 。阀门在其下游管线突然关闭的情况下可以迅速关闭以减静压。一般情况下,所得阀后压力不会高于相应的动压的10%。可调式减压阀是由管道压力启动,导阀自动控制,既减动压、又减静压的减压阀。阀门将减小较高的上游压力并产生一个稳定的较低的下游压力,不受上游压力和流量变化的影响。所获得的下游压力可根据需要通过调节减压导阀上的螺栓来改变.。当上游压力降至所需压力设定值时,导阀使主阀开至zui大程度。当下游压力超过设定压力值时(例如,在消防栓系统中由于减压阀门下游管线水不流动所产生的静压情况下),可调式减压稳压阀立即关闭以减静压,所以不但可以满足常规供水系统的减压要求,而且对于更苛刻的消防静压保持系统,也有*的可靠性,从根本上避免了串压等系统问题。
