Discharging valve

Abstract

The invention discloses a discharging valve. The discharging valve comprises a valve body; two adjusting assemblies which are diagonally arranged are arranged on the valve body, each adjusting assembly comprises a valve plate, a first hinge support, a second hinge support, an electric cylinder, a base and a third hinge support, the first hinge supports are fixed to the inner wall of the valve body, the valve plates are arranged in the valve body, the upper ends of the valve plates are rotationally arranged in the first hinge supports, the second hinge supports are fixed to the outer sides of the lower ends of the valve plates, the bases are arranged outside the valve body, the third hinge supports are fixed to the upper sides of the bases, the electric cylinders are arranged on the side face of the valve body in a penetrating mode, the telescopic ends of the electric cylinders are rotationally connected into the second hinge supports, and the fixed ends of the electric cylinders are rotationally connected into the third hinge supports. According to the discharging valve, stepless control over the opening degree of the valve is achieved, the material flow can be adjusted in real time according to needs, the opening degree of the valve can be adjusted according to the discharging amount of follow-up equipment such as a vertical mill or a roller press so as to adjust the discharging amount, continuous and stable operation of the whole preparation process is guaranteed, and then the production efficiency is improved.

Description

technical field [0001] The invention relates to a feeding valve. Background technique [0002] Cement is a common building material. When the cement plant is producing cement, the upper part of the feed inlet of the external circulation vertical mill or roller press that grinds raw material or cement internally is equipped with a discharge valve to control the on-off of the powder. , Most of the existing feeding valves use rod valves or pneumatic gate valves. However, rod valves and pneumatic gate valves cannot control the size of the material flow, and the valve opening can only be fully open or fully closed. The discharge volume of follow-up equipment such as roller presses is used to adjust the discharge volume of materials in real time. Once the feed volume of subsequent equipment such as vertical mills or roll presses is greater than the discharge volume, the excess materials will overflow. At this time, only Can shut down and stop, and then cause the interruption of t...

Once the feed volume of subsequent equipment such as vertical mills or roll presses is greater than the discharge volume, the excess materials will overflow. At this time, only It can be closed and shut down, which will lead to the interruption of the entire preparation process, resulting in low production efficiency, which needs further improvement
