本装置是为燃气用户的安全研制的,装置分两段工作:当燃气轻微泄漏,空气中燃气浓度较低时,将自动启动排气扇;当泄漏较严重达到高浓度时,还同时发出报警声。如在进户管道加设电磁气阀,本控制器在报警的同时还可通过气阀,切断气源,杜绝事故发生。本控制器是由气敏元件和电子线路组成,电路高度集成化,工作可靠,并设有气敏元件工作状态,监控指示,有效地避免了气敏元件的误报和漏报。 1990年5月15日通过有色总公司南昌公司组织专家评议鉴定,填补省内空白。
This device is developed for the safety of gas users, the device is divided into two sections: When the gas slightly leaked, the gas concentration in the air is low, it will automatically start the exhaust fan; when the leakage is more serious to high concentrations, but also at the same time alarm sound. As in the household pipe plus electromagnetic valve, the controller at the same time in the alarm but also through the valve, cut off the gas source, to prevent accidents. The controller is composed of gas sensors and electronic circuits, the circuit is highly integrated, reliable, and with gas sensor working conditions, monitoring instructions, effectively avoiding false positives and false negatives. May 15, 1990 through the non-ferrous company Nanchang company experts to appraisal, fill the gaps in the province.
