Interlocking control scheme of electric butterfly valve

The invention discloses an interlocking control scheme of an electric butterfly valve, which belongs to the technical field of electrical control, and has the beneficial effects that according to the design of an electric butterfly valve control system, local conditions are adjusted, local materials are used, a simple control loop is used for completely realizing synchronous operation of an unloader and the electric butterfly valve, the loop is clear, wiring is convenient, the labor, the construction period, the design cost and the materials are greatly reduced, and the equipment can be put into normal production and use after short-term construction. After the dust collection butterfly valve control system is additionally arranged, dust in the stock bin is greatly reduced, the working environment is greatly improved, the dust raised when mineral aggregate enters the stock bin is recycled to the batching belt, and waste of the mineral aggregate is avoided. An operator does not need to operate the electric but
