Description

Technology Field

[0001] The present invention relates to a vibration-preventing globe valve assembly, and more specifically, to a vibration-preventing globe valve assembly comprising a main body, a disc, a shaft, a shaft guide, a fixed plate, a rotating plate, and a fixed part, which prevents unnecessary valve opening and closing that may occur due to vibration, thereby increasing process reliability and enhancing safety, and allows for smooth flow control and opening / closing by simply changing the locking device when operating the valve handle, and enables easy switching between locking and unlocking as needed. Background Technology

[0003] Valves used for flow control and opening / closing, particularly globe valves, are generally operated using manual handles. These valves must be open or closed according to their specific applications and perform the function of properly regulating fluid flow. However, in vibrating environments, these valves may open or close unintentionally, contrary to their intended use. This can result in process losses and, in severe cases, cause safety issues.

[0004] The reason the opening and closing state of a valve becomes unstable in such vibrating environments is that vibrations cause the handle to rotate or the internal parts of the valve to loosen. For example, in factories or industrial sites, vibrations generated when machinery is in operation can directly affect the valve, leading to unintended opening and closing. This results in unnecessary fluid flow or blockage, causing process interruptions or quality issues.

[0005] Conventional valves use globe valves and manual handles to control fluid flow. This allows for the opening and closing of the valve, thereby regulating the flow rate and enabling the valve to be opened or closed as needed. However, as mentioned above, this method may be unreliable in vibrating environments and has limitations in solving problems caused by unexpected opening or closing of the valve.

[0006] Therefore, the shortcomings of conventional manual handles, which cannot withstand vibrations due to their simple structure and fail to rotate easily or maintain their position, must be addressed. While some attempt to solve this problem by using strong locking mechanisms, this reduces the handle's operability and makes maintenance difficult. Consequently, a new technology is required that can operate stably even in vibrating environments. Prior art literature
