Description

Technical Field

[0001] The utility model relates to the technical field of cone valves, in particular to a cone valve sealing and fastening device. Background Art

[0002] Cone valve is a commonly used valve type. Its structural feature is that the valve core is conical. The flow and pressure of the medium are controlled by rotating or moving the valve core. Cone valve is widely used in petroleum, chemical, metallurgy, electric power, water treatment and other industries due to its simple structure, good sealing, flexible opening and closing, and long service life. The valve core of the cone valve is conical, which is the origin of its name. The valve body of the cone valve is usually designed as a cylinder with a conical valve core fixed inside. The valve core can adjust the flow area between it and the valve body by rotating or moving, thereby controlling the flow.

After long-term operation, the seal will become loose or displaced, affecting the sealing effect, thereby causing leakage at the connection between the valve stem and the valve seat." However, the installation structure in the above application is too simple and has no obvious optimization compared with the existing structure. Moreover, the fastener in the above application does not have a corresponding limiting structure after being fixed, and the loosening of the fastening structure cannot be avoided after long-term use.
