Description
Technical field
The utility model relates to conveying equipment for fluid substances field, especially a kind of butterfly spring non-return valve.
Background technique
Along with the continuous progress of mechanization, machinery is very general in the application of fluid applications, the butterfly one-way valve of current production is due to the stud connector design between flap and valve body or improper use, often there is the breakage of valve body, fall the phenomenon of lobe, the fluid sound thereupon produced, impact force can not be resolved on the impact of equipment.
Model utility content
The purpose of this utility model is to provide a kind of butterfly spring non-return valve, mainly through installing flap by axle sleeve on through-shaft, mounting spring between axle sleeve, coordinate lining, O-ring, supportive seal ring on through-shaft, make valve body structure firm and simple, flap can be closed rapidly, reduces the collapsing force of fluid hammer, improves the working life of valve body.
In order to achieve the above object, the technical solution of the utility model is:
A kind of butterfly spring non-return valve, comprise valve body, described valve body is provided with valve seat by valve seat orifice, in described valve body, through-shaft is installed, described through-shaft comprises integrally manufactured upper axle, axis, lower shaft, described axis is movably installed with successively the first axle sleeve, the second axle sleeve, the 3rd axle sleeve, the 4th axle sleeve, between described second axle sleeve, the 3rd axle sleeve, spring is installed, described first axle sleeve, the 3rd axle sleeve are provided with the first flap, described second axle sleeve, the 4th axle sleeve are provided with the second flap.
Described upper axle top is provided with Simmer ring, is provided with lining and O-ring successively, described lower shaft is provided with supportive seal ring bottom described upper axle; Described spring comprises the first supporting foot and the second supporting foot, and described first supporting foot is connected with the first flap, and described second supporting foot is connected with the second flap.
