连锁阀 valve interlock的简单介绍

连锁阀 valve interlock的详细信息

In the actual operation process, it is called ”mechanical interlocking" that the key is exchanged in a certain logical order to realize the safe operation process. It is a kind of mechanical device approved by the world safety organization and standard

organization, which can prevent man-made misoperation.

Thepurpose of installing mechanical interlocking is to ensure that theequipment and its auxiliary equipment can operate in accordance with the process set. In order to eliminate the iueparable consequences caused by human error operation.

In petroleum, chemical, powe r and high-risk manufacturing industries, there are a large number of manual operation equipment, electrical equipment, protective safety doors and so on. Accidents caused by misoperation are co1mnon, and serious casualties and economic losses caused by misoperation also occur from time to time. Statistics show that 70% of accidents in the oil and gas industry are caused by human errors. The rapid development of modern industry has further aggravated the risk factors, which are controlled by personnel. However, human beings themselves will be disturbed by extemal factors, such asstress, disease and other factors -all in all, depending on ”human factors”．

上海凯研机械经营阀门锁，阀门机械联锁系统，使生产和维护过程中的人为失误风险降到最低，通常这些失误会导致非常危险的、代价惨痛的后果。阀门机械联锁系统十分简洁、易于安装及操作并且可靠，即使在极端工作条件下，也能确保产品有效地运行。

阀联/阀门锁装置应用于石油化工行业，在维护检修工作中，一些人为干预中断的阀门工艺，需要按照预先设定的逻辑顺序进行操作，阀门机械联锁装置能利用钥匙顺序交换实现控制阀门安全操作的全过程，有效防止人为误操作。

阀门联锁的概念是在化工、电厂等工业生产中的自动调节阀门，它们是按照工艺给定的逻辑条件来控制执行机构的。只要某个与之相关的存在逻辑条件联系的特定的温度、流量、压力、压差等工艺参数发生变化，发出信号，就会触发它的自动动作，执行工艺命令。来达到工艺预先设定的状态，以保证生产处于一种预定的安全状态，来保证工艺的最佳运行或局部甚至整体的启停。
