进口减压阀(进口阀门***)德国奥莱斯
【进口减压阀】详细说明:
阀由主阀、导阀、针阀、球阀、微型过滤器和压力表组成水力控制接管系统。减压阀利用设定调压减压导阀弹簧压力和调节针型阀开度设定出口压力,通过接管系统和控制室的反馈作用来稳定出口压力,不需要附加其它装置和能源,维护***简便,受进口压力和流量影响小,压力控制准确度高,减压稳压可靠。
The valve c***ists of main valve, guide valve, needle valve, ball valve, micro filter and pressure gauge. Pressure relief valve sets outlet pressure by setting spring pressure of pressure regulating and pressure reducing guide valve and adjusting needle valve opening. It stabilizes outlet pressure by feedback of nozzle system and control room. No additional devices and energy are needed. It is easy to maintain and maintain. It is less affected by inlet pressure and flow rate, high accuracy of pressure control and stable pressure relief. Pressure is reliable.
【进口减压阀】工作原理:
四氟密封减压阀介质走向由上进下出,当调节出口压力时,顺时针旋转调节螺栓,迫使活塞向下移动,打开主阀,改变节流面积,造成压力损失,实现减压。由于减压阀阀后介质通过“X”通道流入活塞下腔并与活塞上方保持平衡,当压力和流量变化时,使主阀节流面积始终保持相应位置,由于减压阀采用卸荷机构,减小了进口压力变化对出口压力的影响,同时加大了出口压力作用面积,即加大敏感元件作用面积,从而减小了阀门出口压力偏差,大大提高了减压阀的稳压精度。
When the outlet pressure is adjusted, the adjusting bolt rotates clockwise, forcing the piston to move downward, opening the main valve, changing the throttle area, causing pressure loss and realizing pressure reduction. Because the medium behind the relief valve flows into the lower chamber of the piston through the "X" channel and keeps balance with the top of the piston, the throttle area of the main valve always keeps corresponding position when the pressure and flow change. Because the relief valve adopts the unloading mechani***, the influence of the change of inlet pressure on the outlet pressure is reduced, and the effect of outlet pressure is increased. Area, that is to say, increase the area of sensitive elements, thereby reducing the deviation of valve outlet pressure, greatly improving the pressure stabilization accuracy of pressure relief valve.
【进口减压阀】调压方法:
1、关闭减压阀前的截止阀,开启减压阀后的截止阀,制造下游低压环境。
2、卸下减压阀上端的防护罩调节螺钉按逆时针旋转至***上位置(相对***低出口压力),然后关闭减压阀后截止阀。
3、慢慢开启减压阀前的截止阀至全开。
4、顺时针缓慢旋转调节螺钉,将出口压力调至所需的压力(以阀后表为准)调整后,将锁紧螺母备紧,拧上防护罩,打开减压阀后截止阀。
5、如调压过头,须从***步开始重调。
