上海凯研机械设备有限公司提供阀锁，阀门联锁，阀门机械锁装置，防止人为误操作。阀门机械锁是安装与阀门上的锁定装置，可以将两个或多个阀门锁定后，遵循规定的操作顺序进行安全有序的操作，防止误操作导致事故的发生。
凯研机械公司提供多种类型的阀门机械联锁，适用于各种类型的阀门，如：球阀、蝶阀、闸阀、截止阀、电动阀、盲板阀及管道收发球系统。
阀门机械锁装置特点
1、每台阀门的装置上配备两把不同的带有编码的钥匙，控制阀门的两种状态。
2、装置上留存两把钥匙的条件下，阀门处于可操作状态，通过操作实现钥匙的转换。
3、装置上留存一把钥匙的条件下，阀门处于锁定状态，钥匙的位置标识阀门的状态。
4、通过“钥匙传递”，实现阀门信息的远程传递和状态显示。
5、结构紧凑坚固，操作灵活简便。
6、采用不锈钢材质，产品寿命长久。
7、安装简便，不改变受控阀门的性能和形状，适合于多种类型的阀门。
2、阀门机械锁装置工作原理
初始状态
装置对应的孔位上留存一把钥匙，受控阀门处于初始状态（开或关）
操作状态
根据工艺要求，从控制室取出授权钥匙，插入装置上另一侧对应的孔位，受控阀门处于可操作状态，操作阀门至新的状态（开或关）
结束状态
拔出初始状态中留存的钥匙，并返回控制室，受控阀门锁定于重新设定的状态（开或关）。
3、应用范围
阀门机械联锁主要应用于 油田、石化、化工、核电、冶金、天然气等高危行业中关键阀门的状态锁定、传递和显示（现场和控制室）。
Inthe actual operation process, it is called ”mechanicalinterlocking" that the key is exchanged in a certain logical orderto realize the safe operation process. It is a kind of mechanicaldevice approved by the world safety organization and standardorganization, which can prevent man-mademisoperation.
Thepurposeof installing mechanical interlocking is to ensure thatthee and its auxiliary e can operate in accordancewith the process set. In order to eliminate the iueparableconse caused by human error operation.
Inpetroleum, chemical, powe r and high-risk manufacturing industries,there are a large number of manual operation e, electricale, protective safety doors and so on. Accidents caused bymisoperation are co1mnon, and serious casualties and economiclosses caused by misoperation also occur from time to time.Statistics show that 70% of accidents in the oil and gas industryare caused by human errors. The rapid development of modernindustry has further aggravated the risk factors, which arecontrolled by personnel. However, human beings themselves will be disturbed by extemal factors, such asstress, disease andother factors -all in all, depending on ”humanfactors”．
