In recent years, more and more attention has been paid to the safety factor of manufacturing equipment in out country. In this way, the safety factor of the equipment is greatly improved, and it can completely prevent the occurrence of safety accidents caused by wrong operation.

The valve lockout of the design scheme is unique at the current stage. This valve lockout is mainly operated by a fixed valve handle. One end of the valve lockout is connected with the bonnet anchor bolt. The connection method is made of threaded 2 nuts, connect the drive chain with a pin in the middle, screw one end to the bonnet anchor bolt of its supporting facilities (the threaded nut wire is matched with the bonnet anchor bolt wire), and the other end has a union of the inch thread is connected with the nut of the thread, and the valve handle is circumvented by the drive chain. The two sides of the drive chain are connected with the union of the inch thread with pins, and the handle and the valve cover are connected vertically. The connection method is if the valve is found to be locked, the valve cannot be opened unless the union in the middle is loosened or damaged.

When repairing or opening and closing the valve, it is enough to twist the union in the middle. Valve lockouts are mainly used in some valves that are often closed and open, and some valves that are opened and closed during maintenance, and other valves that must be locked can also be used. A lock can also lock 2 valves, which is mainly to protect it from causing safety accidents due to operational errors.

Proven according to practical activities, it is effective and also saves a lot of raw materials. Valve lockouts have been used in many companies’ power plants, and the actual effect is very good. It is commonly used in each power plant adjustment and maintenance period to prevent operational errors and ensure the safe operation of machinery and equipment.
