Abstract
The utility model relates to a multifunctional valve which comprises a valve body, a valve cap and a valve rod, wherein a valve clack is arranged on the valve rod. The valve clack comprises a cut-off valve clack and a conical valve clack, wherein the cut-off valve clack and the conical valve clack are mutually connected. The material inlet position of the valve body, which corresponds to the conical valve clack, is provided with a conical surface, and a matching surface of the cut-off valve clack is arranged on the inner wall on the valve body, which is adjacent to the material inlet position. The lower surface of the cut-off valve clack, which corresponds to the matching surface of the cut-off valve clack, is provided with a sealing pad made of elastic corrosion resistance materials. When the valve rod is downwards pressed, the sealing pad of the cut-off valve clack is in a tight fit with the matching surface of the cut-off valve clack. After the valve rod continues to press downwards, the conical valve clack is in a tight fit with the conical surface. The multifunctional valve simultaneously has the functions of a cut-off valve and a throttle valve.
Description
Technical field
The utility model 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 be increased equipment cost, if and above-mentioned multiple valve wherein has a valve leak to bring unnecessary trouble to whole medical production system in the use of medical manufacturing mechanism, material is changed, produce microbiological contamination, serious the pernicious phenomenon of pouring in down a chimney can take place also, can bring enormous economic loss to enterprise.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of multifunction valve, and this multifunction valve has possessed the function of stop valve and throttle valve simultaneously.
For this reason, the multifunction valve that the utility model provides comprises valve body, valve gap and valve rod, valve rod is provided with flap, flap comprises by flap and taper valve, wherein taper valve with interconnect by flap, 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, be provided with the sealing gasket of making by the elasticity resistant material by the corresponding flap fitting surface that ends of flap lower surface, when valve rod compresses downwards by the sealing gasket of flap at first with by flap fitting surface drive fit, valve rod continues to press down back taper valve and conical surface drive fit.
Because the valve rod of the utility model multifunction valve is provided with interconnective taper valve and ends flap, 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, be provided with the sealing gasket of making by the elasticity resistant material by the corresponding flap fitting surface that ends of flap lower surface, when valve rod compresses downwards by the sealing gasket of flap at first with by flap fitting surface drive fit, valve rod continues to press down back taper valve and conical surface drive fit.When the utility model multifunction valve 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 the utility model multifunction valve is slowly opened, this structure can replace the function of throttle valve substantially, so the utility model multifunction valve can replace stop valve, realize three-in-one control on the basis of throttle valve and membrane valve.
