valve interlock

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 thattheequipment and its auxiliary equipment can operate in accordancewith the process set. In order to eliminate the iueparableconsequences caused by human error operation. 

Inpetroleum, chemical, powe r and high-risk manufacturing industries,there are a large number of manual operation equipment, electricalequipment, 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”． 

Valvesafety mechanical interlock 

In manyindustrial processes, valves play a very important role in safety.A misoperation of a valve can lead to a series of dramatic andserious consequences - personal injury, factmy damage, and evenirTeparable environmental pollution. Therefore, the valve safetyoperation must be effectively monitored. Through the use of Kaiyanvalve mechanical interlocking can ensure that always in accordancewith the correct order of operation.

Kaiyanvalve mechanical interlocking device can be installed in eachhandle or handwheel operated valve, without adjusting, altering ordestroying the original valve equipment. The intedocking device isve1y strong and easy to operate and clearly display the switchingstatus of each valve．

Professionallydesigned customized keys and interlocks make assembly without anyadjustment or processing. We will provide a full set ofinterlocking system and installation and commissioning services, sothat you have no worries. Provide a set of special tools foron-site emergency adjustment o「 expansionof on-site safety system. Unique designed dust-p「oofsealing cover prevents dust or sediment from entering thekeyhole.
