Description
Technical field
The utility model is related to butterfly valve field, more particularly to a kind of hydraulic control slow closing non-return butterfly valve.
Background technology
At present, industrial valves door type is various, can be widely applied to the industries such as chemical industry, food, water, electricity, primarily serves stream
The Flow-rate adjustment of body medium is acted on cut-off.
Butterfly valve refers to that valve plate rotates to reach a kind of valve of open and close around valve rod, cut-out is acted primarily as on pipeline and is saved
The effect of stream.Two kinds of seal forms of the flexible soft seal of butterfly valve and metal hard-sealing, the valve of metal hard-sealing is typically close than soft
The life of valve of envelope is long, can the higher working environment of Applicable temperature, but sealing property not as the valve of soft seal it is good.
Butterfly valve is one of valve at present used in all trades and professions widely, lightweight due to butterfly valve small volume, is opened
Open conveniently, but there is also some bad phenomenons, particularly hydraulic butterfly valve generally existing the valve when valve is opened and produced and shakes
Dynamic, when pressurize is unstable easy, butterfly plate returns certain closing angle, causes current flow resistance to increase；Furthermore it is exactly to produce at sealing surface
Erosion of getting rusty makes valve switch be obstructed, and causes damage of sealing ring etc. phenomenon.
Utility model content
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provide a kind of simple structure, reality
Hydraulic control slow closing non-return butterfly valve.
The utility model is realized in the following way：
A kind of hydraulic control slow closing non-return butterfly valve, it is characterised in that：Including valve body 1, butterfly plate 2, stream chamber is provided with the valve body 1；
Valve shaft 3 is equipped with the butterfly plate 2；The left and right two ends of the valve shaft 3 are connected respectively with valve body 1；The butterfly plate 2 is located at stream chamber
It is interior；The valve shaft 3 is rotatable relative to valve body 1；Support 4 is connected with the valve body 1, the He of weight 9 is connected with the support 4
