Description
Technical field
The present invention relates to a kind of valve, especially a kind of multifunction valve that is used for the process equipment of industries such as medicine, biology and food.
Background technique
That sells in the market is used for medicine, valve on the process equipment of industries such as biology and food all is the valve of individualism, but often discovery need be installed multiple valve simultaneously on same pipeline in the process equipment of these industries, for example just stop valve need be installed simultaneously on the pipeline between fermenting tub in medical manufacturing mechanism and the refinement jar, throttle valve and membrane valve, these valves are installed when not only taking a lot of work respectively on same pipeline, and in process of production owing to need the operating stem of control too much to bother very much, a plurality of valves are installed in addition simultaneously can increase equipment cost.
Summary of the invention
Technical problem to be solved by this invention provides a kind of multifunction valve, and this multifunction valve has possessed the function of stop valve and throttle valve simultaneously.
For this reason, multifunction valve provided by the invention comprises valve body, valve gap and valve rod, and valve rod is provided with flap, and flap comprises by flap and taper valve, wherein taper valve with interconnect by flap, taper valve can be relatively by flap along axial direction elastic telescopic up and down; The corresponding taper valve in the material inlet place of valve body is provided with the conical surface, the inwall at contiguous material inlet place is provided with by the flap fitting surface on the valve body, when valve rod compresses downwards taper valve can with conical surface drive fit, by flap can with by flap fitting surface drive fit.
Because the valve rod of multifunction valve of the present invention is provided with interconnective taper valve and ends flap, taper valve can be relatively by flap elastic telescopic up and down vertically, the corresponding taper valve in the material inlet place of valve body is provided with the conical surface, the inwall at contiguous material inlet place is provided with by the flap fitting surface on the valve body, when valve rod compresses downwards taper valve can with conical surface drive fit, by flap can with by flap fitting surface drive fit.When multifunction valve of the present invention is closed the drive fit of the taper valve and the conical surface and by flap with the valve interior wall at contiguous material inlet place on the drive fit by the flap fitting surface realized the double seal effect, this sealing effect has met or exceeded the sealing effect that stop valve and membrane valve are installed respectively, the flow pass of material slowly becomes big in the process of moving on the taper valve when multifunction valve of the present invention is slowly opened, this structure can replace the function of throttle valve substantially, so multifunction valve of the present invention can replace stop valve, realize three-in-one control on the basis of throttle valve and membrane valve.
