Abstract
The invention relates to a multifunctional butterfly valve which comprises a butterfly plate. The other side face of a butterfly plate body is a hemispherical arc-shaped surface. A plurality of hollow cavities are formed in the portion, between an upper connecting part and a lower connecting part, of the interior of the butterfly plate body. The butterfly valve is provided with an external bolt and nut, an internal bolt and nut and an adjusting bolt and nut. A valve body is made of nodular iron. A stainless steel layer is welded to the sealing surface of the valve body in a surfacing mode. Through the arrangement of the hemispherical arc-shaped surface of the butterfly valve, flow resistance of the valve plate is greatly reduced; moreover, the hemispherical arc-shaped surface is not likely to produce eddy currents, the supporting force is also greatly enhanced, and the service life of the valve plate is prolonged; through the arrangement of the hollow cavities, the weight of the valve plate is reduced; through the arrangement of the external bolt and nut, the internal bolt and nut and the adjusting bolt and nut, the height of the valve plate can be adjusted up and down according to the actual conditions, and the requirements for application on different occasions are met; the valve body is made of the nodular iron, and the sealing surface of the valve body is provided with the stainless steel in the surfacing mode, so that the service life of the butterfly valve is prolonged.
Description
Technical field
The invention belongs to valve technology field, especially a kind of multi-functional butterfly valve.
Background technology
Valve (famen) is the function unit in fluid delivery system, has cut-off, adjustment, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief. For the valve of fluid control system, various valves used from the simplest stopping valve to very complicated robot control system(RCS), its kind and specification are quite various. Valve can be used for controlling the flowing of all kinds fluids such as air, water, steam, various corrosive medium, mud, oil product, liquid metal and radiating medium. Industrial valves door type is varied, is widely used in the industries such as chemical industry, food, water, electricity, mainly plays Flow-rate adjustment and the cut-off effect of fluid medium.
The valve plate of the butterfly valve being applicable to water or sewage of the prior art is mostly iron and steel material quality, and valve plate is all solid mostly, weight is all heavier, and this not only brings great inconvenience to the carrying of operator, operation etc., and greatly waste starting material, waste resource; The outside surface of the valve plate of existing butterfly valve is mostly plane, and plane is not good by power, discontinuity, it is easy to produces eddy current, brings great inconvenience to use.
In addition, the butterfly plate of butterfly valve of the prior art is in the process used, owing to operating for a long time, along with the prolongation of duration of service, under waiting the impact of other factors under gravity, butterfly plate can move downward, thus can greatly reduce the stopping property of butterfly valve, bring great inconvenience to the use of user, also can give simultaneously and use enterprise to cause financial loss; And, butterfly plate is in the use procedure of reality sometimes, and the height of the butterfly plate used due to different occasions is also not quite similar, and owing to the installation position of butterfly plate is certain, therefore also brings inconvenience to use, reduces the use range of butterfly valve.
