Abstract
The utility model relates to a labyrinth sealing valve comprising a valve cover, a valve body and a sealing element, and is characterized in that a connecting face of the valve cover and the valve body is provided with a boss and a groove which are matched with each other, and the sealing element is arranged on the bottom of the groove. The labyrinth sealing valve has the advantages of being simple in structure, convenient to process and good in sealing effect.
Description
Technical field
The utility model relates to a kind of sealed valve, particularly relates to a kind of labyrinth sealing valve.
Background technique
Valve is one of vitals that often uses in the industrial processes; Find that in long-term practice process all there is the defective of sealing difference in traditional valve, people often improve the sealing of valve through the mode of on the junction surface of valve gap and valve body, setting up pad for this reason; But find through long-term using effect; The sealing effect of this mode still can't reach industrial needs, simultaneously, and in the frequent opening and closing process of valve; Pad is very easy to wearing and tearing, has greatly reduced the sealing effect of valve.
Summary of the invention
The technical problem that the utility model will solve is: existing sealed valve is improved, a kind of labyrinth sealing valve of simple in structure, good seal performance is provided.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of labyrinth sealing valve comprises: valve gap and valve body, Sealing; It is characterized in that: the junction surface of said valve gap and valve body is provided with the boss and the groove of mutual coupling, and Sealing places the bottom of groove.
As preferred version, the utility model has also adopted following technical measures:
Said valve gap is provided with boss, and said valve body is provided with groove.
Said valve gap is provided with groove, and said valve body is provided with boss.
Said Sealing is an asbestos packing.
The longitudinal section of said boss is stepped.
Said boss has a step at least.
The longitudinal section of said groove is stepped.
Said groove has a step at least.
Advantage and the good effect that the utlity model has are: one, through the boss and the groove of mutual coupling are set, improved the sealing of valve on the junction surface of valve gap and valve body; Two, through in the middle of boss and groove, asbestos packing being set, dwindled because the space of expanding with heat and contract with cold and producing between the valve gap that causes and the valve body, further increased the sealing of valve; Three, simple in structure, be easy to processing.
