This shows, the technical problem that exists in prior art is, the valve plate corrosion-vulnerable of butterfly valve; Valve plate is subjected to the erosive wear degree of medium high; Butterfly valve plate is because the reasons in structure fluid medium produces inhibition.
The model utility content
Goal of the invention of the present utility model is: the problem for prior art exists provides a kind of butterfly valve plate.Solve the valve plate corrosion-vulnerable of butterfly valve; Valve plate is subjected to the erosive wear degree of medium high; Butterfly valve plate produces the technical problem of inhibition due to the reasons in structure fluid medium.
To achieve these goals, the technical solution adopted in the utility model is:
The purpose of this utility model is to provide a kind of butterfly valve plate, a kind of, anti abrasive valve plate more anticorrosive than nickel-chromium stainless steel.
The utility model adopts and strengthens polyphenylene sulfide/polytetrafluoroethylalloy alloy (PPS/PTFE) material, and by molded butterfly valve plate, corrosion resistance, wear resistance performance all are better than nickel-chromium stainless steel, and fed sheet of a media is not produced secondary pollution.Adopt the PPS/PTFE material molded, simple and fast, size is accurate, and is with low cost.
This nonmetallic material Mechanics of Machinery intensity is suitable with nickel/chromium stainless steel, and its corrosion resistance, wear resistance performance all are better than stainless steel.The valve plate of making, life cycle is long, and is with low cost.
For guaranteeing that product reaches general effect, it adopts GB GB/T 12238 flanges to be connected elastic packing butterfly valve standard measure with being connected to press from both sides with the part that the butterfly valve housing is associated.All the other sizes are all by the selected properties of materials parameter designing of the utility model.Especially the valve pole is designed the two ends bolt-type, increase the valve plate central segment and cross fluid space, namely improved inflow-rate of water turbine, the Chongqing had reduced to cross flow resistance and housing pressure again, had more reduced valve plate and had been washed away the abrasion earthquake intensity.Light than the operation of stainless steel valve plate, extended working life, reduced user cost.
A kind of butterfly valve plate comprises plate body and the valve pole that is connected connecting valve rod, and plate body and valve pole are one-body molded, and the radially two ends of described plate body are provided with two valve poles, and described valve pole inside is provided with the valve rod groove that matches with valve rod.
As preferred version of the present utility model, described valve pole is two, coaxial being arranged on plate body.
As preferred version of the present utility model, the joint between the valve pole is level and smooth curved surface.
As preferred version of the present utility model, described valve rod groove is circle hole groove or square hole groove.
