Definition: The valve lock is mainly used to lock the valve and protect the safety of the valve.
Valve locks belong to a category of industrial safety locks. The purpose is to ensure that the equipment using the valve is absolutely closed and the equipment is kept in a safe state. The use of locks can prevent accidental operation of the equipment, causing injury or death, and another purpose is to serve as a warning.
The commonly used valve locks are divided into ball valve locks, butterfly valve locks, gate valve locks, rotary valve locks, and universal valve locks.
Ball valve lock is mainly used to lock the ball valve to protect the safety of the ball valve.
The gate valve lock is suitable for the locking work of the gate valve, and can better protect the safety of the gate valve.
The butterfly valve lock is suitable for locking all butterfly valves of common specifications, which better protects the butterfly valve switches and prevents accidental accidents.
Valve lock products on the market are also uneven, good and bad, so you need to pay attention to the following points when choosing brand and model:
2. The valve lock can be selected from a variety of materials, and the appropriate lock can be selected according to the environment in which the lock is used, such as air dry humidity, whether it is high temperature, and whether it needs acid and alkali resistance.
3. Looking at the safety standards, there are very strict standards for hardware locks at home and abroad. Small manufacturers will not implement the standards in order to save costs, and large brands will generally comply with the standards.
4, valve size, different valve considerations are different, choose the matching valve lock.
5. Check whether the label and mark of the valve lock package are complete (including the product's implementation standard, grade, manufacturer's name, address, and production date). The package is firm. The content of the instruction manual is consistent with the product. phenomenon.
5 pipeline applications:
Pipeline valves in power plants are very important auxiliary equipment during operation. It is related to the importance of safe operation. Some valves are always open and some valves are often closed. This requires safety considerations to avoid misoperation, so the author designed a valve lock. , Mainly used for normally open and normally closed valve use or temporary use, can ensure that the operator and non-operating personnel to prevent the wrong operation of the valve.
Safety Electrical Lockout
In recent years, the country has paid more and more attention to the safety of production equipment, which has greatly improved the safety of the equipment and can completely avoid accidents caused by human error. Safety electrical lockout has been applied in various power plants, and the effect is very good, ensuring the safe operation of the equipment.
