求可燃气体报警器的外文文献2份！

【专家解说】：在中国逐步进入工业化的同时，中国每年发生的工业事故也在屡屡发生。煤矿爆炸、厂房起火、工人中毒等此类新闻报道层出不穷。这些事故的发生主要因为工业环境中使用易燃易爆、有毒有害气体不当造成。对此中国政府不断推出相关法令来预防工业事故的发生：2002年6月29日中华人民共和国第九届全国人民代表大会常务委员会第二十八次会议通过了《中华人民共和国安全生产法》，自2002年11月1日起施行。各个省市也作出相关法令：2006年3月30日山东省第十届人民代表大会常务委员会第十九次会议通过了《山东省安全生产条例》本条例自2006年6月1日起施行。 什么是气体报警器？ 顾名思义气体报警器就是气体泄露检测报警仪器。当工业环境中可燃或有毒气体泄露时，当气体报警器检测到气体浓度达到爆炸或中毒报警器设置的临界点时，报警器就会发出报警信号，以提醒工作采取安全措施，并驱动排风、切断、喷淋系统，防止发生爆炸、火灾、中毒事故，从而保障安全生产。 气体报警器的结构构成： 工业用固定式气体报警器由报警控制器和探测器组成，控制器可放置于值班室内，主要对各监测点进行控制，探测器安装于气体最易泄露的地点，其核心部件为内置的气体传感器，传感器检测空气中气体的浓度。探测器将传感器检测到的气体浓度转换成电信号，通过线缆传输到控制器，气体浓度越高，电信号越强，当气体浓度达到或超过报警控制器设置的报警点时，报警器发出报警信号，并可启动电磁阀、排气扇等外联设备，自动排除隐患。 便携式气体检测仪为手持式，工作人员可随身携带，检测不同地点的气体浓度，便携式气体检测仪集控制器，探测器于一体，小巧灵活。与固定式气体报警器相比主要区别是便携式气体检测仪不能外联其他设备。 气体报警器的分类 按检测气体可分为：可燃气体报警器，有毒气体报警器和复合式气体报警器，气体报警器使用不同传感器检测不同气体 ，复合式气体报警器可同时检测可燃和有毒气体。按使用环境可分为：工业用气体报警器和家用燃气报警器。按自身形态可分为固定式气体报警器和便携式气体检测仪。 Enters the industrialization gradually while China, the industrial accident which China occurs every year repeatedly is also occurring. The coal-mine explosion, the workshop are on fire, the worker poison and so on this kind of reportage to emerge one after another incessantly. Because these accident's occurrence mainly in the industry environment uses flammable explosive, the virulent noxious gas to create improper. Regarding the Chinese government promotes the related law to prevent industrial accident's occurrence unceasingly: on June 29, 2002 the People's Republic of China ninth Standing Committee of the National People's Congress 28th conference adopted "the People's Republic of China Safety in production Law", became effective from November 1, 2002. Each provinces and cities also make the related law: on March 30, 2006 Shandong Province tenth session of the National People's Congress Standing committee 19th conference adopted "Shandong Province Safety in production Rule" this rule becomes effective from June 1, 2006. what is the gas alarm apparatus? the gas alarm apparatus are the gas revelation examination warning instrument as the name suggests. When in industry environment inflammable or noxious gas revelation, when the gas alarm apparatus examine the gas strength to achieve the critical point which the detonation or the toxicant alarm apparatus establish, the alarm apparatus will send out the alarm, will remind the work to take the security measure, and will actuate a row of wind, the cut-off, to spray the system, will prevent to have the detonation, the fire, the toxicant accident, will thus safeguard the safety in production. gas alarm apparatus' structure constitution: the industrial used stationary type gas alarm apparatus are composed of the warning controller and the detector, the controller may lay aside in the duty officers observation room, mainly carries on the control to various test points, the detector installment the place which is easiest in the gas to reveal, its core part for built-in gas sensor, in sensor examination air gas density. Detector the gas strength which examines the sensor transforms the electrical signal, passes commits a footfault the cable to transmit the controller, the gas strength is higher, the electrical signal is stronger, when the gas strength achieves or surpasses the alarm point which the warning controller establishes, the alarm apparatus send out the alarm, and may start the solenoid valve, the exhaust fan substandard association equipment, removes the hidden danger automatically. the portable gas instrumentation is the handhold, the staff may body carrying, the examination different place gas strength, portable gas instrumentation collection controller, detector in a body, exquisite nimble. Compares the main difference with the stationary gas alarm apparatus is the portable gas instrumentation cannot outside unite other equipment. gas alarm apparatus' classified may divide into according to the examination gas: The flammable gas alarm apparatus, the noxious gas alarm apparatus and the compound expression gas alarm apparatus, gas alarm apparatus use different sensor examination different gas , the compound expression gas alarm apparatus may simultaneously examine inflammable and the noxious gas. May divide into according to the use environment: Industrial used gas alarm apparatus and home use fuel gas alarm apparatus. May divide into the stationary gas alarm apparatus and the portable gas instrumentation according to own shape.
