意大利惭础顿础厂马达斯调压阀是杠杆式压差反馈控制调压的。气瓶里的燃气是液态的,压力太高,必须减压才适合通往炉具燃烧。煤气调压阀坏了必须换新的。后果1,不出气;后果2,不减压。
不减压,容易造成胶管脱落,泄漏燃气,后果不堪设想。减压原理:高压介质通过一个小孔充到一个相对较大的腔里实现减压,实际上是靠截流减压。膜片或活塞的两面一面是出口腔,一面是人为给的压力,并且控制小孔大小的阀杆和膜片(活塞)相连。
马达斯惭础顿础厂燃烧炉调压阀气体压力调节器(高笔2)
FRG / 2MCSH- RG / 2MCSH =没有安全关闭装置的滤波器调节器和调节器
FRG / 2MBH ... - RG / 2MBH ... =过滤调节器和带安全关闭装置的调节器
它可以配备以下安全装置和配件:
出口过压关闭装置(仅2MBH ......版本):当调节器出口压力上升到设备设定值时,它会停止气流
安全阀:如果有下游调节器超压,它会排出少量气体。 如果安装在通风不良的环境中,那么它在外面被排气
出口低压关闭装置(仅2MBH ......版本):当调节器出口压力下降到设备设定值时,它会停止气流。 即使没有入口压力,它也会关闭。
出口压力测试点。
入口过滤器(FRG / 2MBH ...- FRG / 2MCSH DN 15 - 20 - 25)
参考标准EN 88-2 - 334

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)
Reference standard EN 88-2 - 334
