Description

Flue valve sealing detection device

Technical Field

The utility model relates to the technical field of valve detection, in particular to a device for detecting the sealing performance of a flue valve.

Background technique

The sealing performance of a valve refers to the ability of each sealing part of the valve to prevent the leakage of the medium. It is the most important technical performance indicator of the valve. There are three sealing parts of the valve: the contact between the opening and closing parts and the two sealing surfaces of the valve seat; the matching part between the packing and the valve stem and the stuffing box; the connection between the valve body and the valve cover. With the continuous increase in energy applications, the application of valves has involved various fields of production and life. At present, the most used valves are mainly linear valves, that is, the valve ports at both ends of the valve are arranged on the same axis.
