Description
Technical field
This utility model is related to a kind of butterfly valve.
Background technology
Butterfly valve is a kind of regulating valve of simple structure, can be used for the on-off control of low pressure pipeline medium, and butterfly valve is around valve
Reaching a kind of valve of open and close, valve can be used to control all kinds such as air, water vapour, mud, oil product for axle rotation
The flowing of fluid, existing butterfly valve elasticity are poor, affect its sealing property.
Utility model content
In view of the deficiency that background technology is present, technical problem to be solved in the utility model is to provide a kind of simple structure
And the butterfly valve of good seal performance.
This utility model adopts the following technical scheme that to complete：A kind of butterfly valve, including valve body, valve rod, valve seat and valve
Plate, the valve rod are connected and control the rotation of valve plate through valve body with valve plate, are provided with left flap and right flap, institute in the valve plate
State in valve body and be provided with annular lug, the annular lug both sides are provided with first annular step and the second ring-shaped step, described
Elastic ring is provided between first annular step and valve rod, the valve plate edge is provided with step chuck, the step chuck card
On second step, the valve seat and valve body bolt connection are provided with flexibly positioned circle between valve seat, valve body and valve plate, described
Valve rod with valve body be connected through valve body and by valve gap.
In this utility model, the simple structure of butterfly valve, the step chuck on valve plate are tight with the second ring-shaped step on valve body
Close connection, is provided with flexibly positioned circle between valve seat, valve body and valve plate, make sealing property between valve seat, valve body and valve plate three
Preferably, the outer rim of the diameter with diameter greater than annular lug of the valve seat and flexibly positioned circle, left flap and right flap is being closed
State is tightly connected with flexibly positioned circle, it is ensured that the sealing property of its closed mode.
Description of the drawings
This utility model has drawings described below：
The structural representation of the butterfly valve that Fig. 1 is provided for this utility model.
Fig. 2 is the cross-sectional schematic of the butterfly valve in Fig. 1.
