MADAS调压器，MADAS燃气减压阀
MADAS马达斯燃气减压阀的工作原理，我们知道，液化石油气从钢瓶出来时为高压气体先通过进气管到达减压室，当用户关闭燃气具的开关时，随着进入减压室的液化石油气增多，其压力升高，把由弹簧压着的橡胶薄膜顶上去，存在于上气室的部分空气由呼吸孔排出阀体。：刘，： : 这样，迫使杠杆向上移动，利用杠杆作用使阀口关闭，切断了液化石油气进口的通路，减压阀出口的压力就不再上升。当打开燃气具的开关后，液化石油气从减压阀内流出，使减压室内的压力下降，橡胶薄膜下凹，带动杠杆下移，外部空气从呼吸孔进入上气室，使阀垫向中移动，进气喷嘴变大，进气量增加，压力升高。这样反复不断的调节过程使减压室的压力总是恒定的，即不管进气压力偏高还是偏低，出口压力总是稳定的，从而直到降压和稳压的作用。MADAS马达斯减压阀是安装在液化气钢瓶角阀上连接角阀与胶管，起到降低输出压力和稳定输出压力的*具配套中的重要燃气设备，具有结构简单、压力稳定、重量轻、调节安装方便等优点。主要由进气口、出气口、手轮、上阀盖、下阀盖、进气嘴、呼吸孔、上气室、减压室、阀垫、杠杆、橡胶薄膜、弹簧、调节螺塞等部件组成。

GAS/AIR RATIO CONTROL REGULATOR - ZERO REGULATOR
AGP/RC - AG/RC

AGP/RC - AG/RC

This device can be used as:

Zero governor, keeps the downstream pressure at zero even changing the flow request;

Air/gas ratio device, keeps constantly the air/gas ratio even changing air pressure.

If used as ratio regulator, it is possible to set it to obtain an air/gas mixing =1:1 or, using the modification kit a mix proportional from a ratio 1:2 to a ratio 1:10.

It can be supplied even on version with mixing gas/air ratio 2:1 – 10:1.

DN 15, DN 20 and DN 25 connections are also available in compact version (code AGP).
