MADAS燃燒爐調(diào)壓閥,MADAS電廠配件
意大利MADAS馬達(dá)斯調(diào)壓閥是杠桿式壓差反饋控制調(diào)壓的。氣瓶里的燃?xì)馐且簯B(tài)的，壓力太高，必須減壓才適合通往爐具燃燒。煤氣調(diào)壓閥壞了必須換新的。后果1，不出氣;后果2，不減壓。
不減壓，容易造成膠管脫落，泄漏燃?xì)猓蠊豢霸O(shè)想。減壓原理:高壓介質(zhì)通過一個小孔充到一個相對較大的腔里實現(xiàn)減壓，實際上是靠截流減壓。膜片或活塞的兩面一面是出口腔，一面是人為給的壓力，并且控制小孔大小的閥桿和膜片(活塞)相連。

FRG / 2MCSH- RG / 2MCSH =沒有安全關(guān)閉裝置的濾波器調(diào)節(jié)器和調(diào)節(jié)器
FRG / 2MBH ... - RG / 2MBH ... =過濾調(diào)節(jié)器和帶安全關(guān)閉裝置的調(diào)節(jié)器
它可以配備以下安全裝置和配件：
出口過壓關(guān)閉裝置（僅2MBH ......版本）：當(dāng)調(diào)節(jié)器出口壓力上升到設(shè)備設(shè)定值時，它會停止氣流
安全閥：如果有下游調(diào)節(jié)器超壓，它會排出少量氣體。 如果安裝在通風(fēng)不良的環(huán)境中，那么它在外面被排氣
出口低壓關(guān)閉裝置（僅2MBH ......版本）：當(dāng)調(diào)節(jié)器出口壓力下降到設(shè)備設(shè)定值時，它會停止氣流。 即使沒有入口壓力，它也會關(guān)閉。

GAS PRESSURE REGULATOR (HIGH P2)

FRG/2MCSH- RG/2MCSH= Filter regulators and Regulators without safety shut off device

FRG/2MBH... - RG/2MBH... = Filter regulators and Regulators with safety shut off device



It can be equipped with the following safety devices and accessory:

outlet over pressure shut off device (only 2MBH... versions): it stops the gas flow when the regulator outlet pressure goes up the device setting value

relief valve: it vents outside small quantity of gas in case there are downstream regulator overpressure. That exhaust it is convoyed outside in case of installation in environment with bad ventilation


outlet low pressure shut off device (only 2MBH... versions): it stops the gas flow when the regulator outlet pressure goes down the device setting value. It closes even if there is no inlet pressure.

outlet pressure test point.

inlet filter (only on FRG/2MBH...-FRG/2MCSH DN 15 - 20 - 25)
