valve mechanical interlock 阀门锁

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 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 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, br>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 sediment from entering the keyhole.
