MADAS調壓器，MADAS燃氣減壓閥
MADAS馬達斯燃氣減壓閥的工作原理，我們知道，液化石油氣從鋼瓶出來時為高壓氣體先通過進氣管到達減壓室，當用戶關閉燃氣具的開關時，隨著進入減壓室的液化石油氣增多，其壓力升高，把由彈簧壓著的橡膠薄膜頂上去，存在于上氣室的部分空氣由呼吸孔排出閥體。：劉，： : 這樣，迫使杠桿向上移動，利用杠桿作用使閥口關閉，切斷了液化石油氣進口的通路，減壓閥出口的壓力就不再上升。當打開燃氣具的開關后，液化石油氣從減壓閥內流出，使減壓室內的壓力下降，橡膠薄膜下凹，帶動杠桿下移，外部空氣從呼吸孔進入上氣室，使閥墊向中移動，進氣噴嘴變大，進氣量增加，壓力升高。這樣反復不斷的調節(jié)過程使減壓室的壓力總是恒定的，即不管進氣壓力偏高還是偏低，出口壓力總是穩(wěn)定的，從而直到降壓和穩(wěn)壓的作用。MADAS馬達斯減壓閥是安裝在液化氣鋼瓶角閥上連接角閥與膠管，起到降低輸出壓力和穩(wěn)定輸出壓力的*具配套中的重要燃氣設備，具有結構簡單、壓力穩(wěn)定、重量輕、調節(jié)安裝方便等優(yōu)點。主要由進氣口、出氣口、手輪、上閥蓋、下閥蓋、進氣嘴、呼吸孔、上氣室、減壓室、閥墊、杠桿、橡膠薄膜、彈簧、調節(jié)螺塞等部件組成。

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).
