LLK系列流量开关是江苏省扬中县机械仪表厂借鉴国外新产品研制而成的。它可对管道中液体流量直接进行监视,当流量低于规定值时能自动发出信号,是自控系统中保护、联锁和报警最理想的信号开关,具有结构简单、动作可靠、调整方便等特点。它适用于电站、冶金、石化等行业的自动控制系统,对主、辅设备的冷却水,密封水、润滑油及密封油等的流量进行监控,以确保主、辅设备安全可靠地运行。该产品年初通过机械工业部上海工业自动化仪表研究所试验测定。
LLK series flow switch is Yangzhong County, Jiangsu Province, the mechanical instrument factory developed from new foreign products made. It can directly monitor the flow of liquid in the pipeline, when the flow rate is lower than the specified value can automatically send a signal, is automatic control system protection, interlocking and alarm the best signal switch, with simple structure, reliable action, easy adjustment . It is suitable for power plant, metallurgy, petrochemical and other industries of automatic control system, the main and auxiliary equipment cooling water, sealing water, lubricating oil and sealing oil flow monitoring, to ensure that the main and auxiliary equipment safe and reliable operation. The product was initially tested by the Shanghai Institute of Industrial Automation Instrumentation, Ministry of Machinery Industry.
