Description

Technical Field

[0001] The utility model belongs to the technical field of valve bodies, and particularly relates to a globe valve. Background Art

[0002] A globe valve is a commonly used cut-off valve, mainly used to fully open or close a fluid passage. Its working principle is to use the lifting of the valve flap to achieve the opening and closing of the valve. Globe valves are widely used in pipeline systems in fields such as municipal, electric power, petroleum, and chemical industries.

[0003] In actual use of existing valve bodies, there is usually no limiting structure inside the valve body. When the valve body is opened and closed for transmission, the impact force generated during opening is relatively large, which will damage the inside of the valve body, thereby reducing the service life of the valve body. Therefore, it is necessary to provide a globe valve to reduce the impact force and increase the service life of the valve body. Summary of the Utility Model
