valveinterlock

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”．


Valve safety mechanical interlock

In many industrial processes, valves play a very important role in safety. A misoperation of a valve can lead to a series of dramatic and serious consequences - personal injury, factmy damage, and even irTeparable environmental pollution. Therefore, the valve safety operation must be effectively monitored. Through the use of Kaiyan valve mechanical interlocking can ensure that always in accordance with the correct order of operation.
Kaiyan valve mechanical interlocking device can be installed in each handle or handwheel operated valve, without adjusting, altering or destroying the original valve equipment. The intedocking device is ve1y strong and easy to operate and clearly display the switching status of each valve．

Professionally designed customized keys and interlocks make assembly without any adjustment or processing. We will provide a full set of interlocking system and installation and commissioning services, so that you have no worries. Provide a set of special tools for on-site emergency adjustment o「 expansion of on-site safety system. Unique designed dust-p「oof sealing cover prevents dust or sediment from entering the keyhole.
