Description

Safety chemical pipeline valve Technical Field The utility model relates to the technical field of pipeline valves, in particular to a safe chemical pipeline valve. Background The chemical pipeline valve is installed in the chemical pipeline system and used for controlling the flowing state of fluid, and comprises a device with functions of cutting off, adjusting flow, changing flow direction, preventing backflow, stabilizing pressure or relieving pressure and the like. The valve is various, and can be divided into a gate valve, a stop valve, a ball valve, a butterfly valve, a check valve and the like according to purposes, and different types of valve structures and working principles are different, for example, the ball valve is opened and closed through rotation of a ball body, and the butterfly valve controls flow through rotation of a butterfly plate. The chemical pipeline valve has the characteristics of corrosion resistance, high temperature resistance, good sealing performance and the like, is suitable for complex media and working conditions in chemical production, ensures the safe, stable and efficient operation of a pipeline system, and is an indispensable key component in the chemical production flow. In the current chemical pipeline system, the valve can realize reliable sealing and conducting functions, but the traditional manual operation mode has obvious potential safety hazards. When the medium in the pipeline has the sudden conditions of overpressure, leakage or abnormal temperature, the operator needs to rush to the scene to manually screw the valve to switch the state, and the process often generates time delay due to factors such as distance, road condition or environmental hazard. For example, in an emergency scene of sudden pressure rise of a chemical reaction kettle, the medium may break through the sealing layer of the pipeline in a short time when the pressure of the chemical reaction kettle is manually sent to the valve, so that leakage and even deflagration accidents are caused. Disclosure of utility model The utility model provides a safe chemical pipeline valve which can remotely control the chemical pipeline valve, quickly switch and reduce adverse effects caused by accidents. In order to solve the technical problems, the technical scheme provided by the utility model is that the safety chemical pipeline valve comprises: the valve body is internally provided with a ball valve, the upper end of the ball valve is connected with a rotating wheel through a connecting shaft, and the rotating wheel is arranged above the valve body; The driving mechanism comprises a motor and a crank, the valve body is connected with a fixing frame, the motor is fixedly arranged on the fixing frame, one end of the crank is fixedly arranged at the output end of the motor, and the other end of the crank is rotationally connected with the edge of the rotating wheel; The auxiliary assembly comprises a high-definition industrial camera and a leakage gas detector, wherein the high-definition industrial camera and the leakage gas detector are fixedly arranged on a fixing frame and are arranged towards a valve body. Further, flanges are arranged at two ends of the valve body. Further, the joint of the connecting shaft and the valve body is connected through a sealing bearing. Further, the motor is arranged right above the center of the rotating wheel. Further, the lamp plate is symmetrically arranged on two sides of the fixing frame, and the illuminating lamp is arranged below the lamp plate. Further, the lamp panel extends out of the end and is arranged in a downward inclined mode, and the illuminating lamp is fixedly arranged on the lower wall of one end, far away from the fixing frame, of the lamp panel. Compared with the prior art, the rigid transmission structure has the advantages that the combination of the motor and the crank in the driving mechanism can remotely send an instruction through the electric control system, the output driving force of the motor is vertically transmitted to the rotating wheel through the crank, the rigid transmission structure can realize the instant opening and closing of the ball valve, compared with the traditional manual operation, the opening and closing time is greatly shortened, and when the emergency conditions such as pressure abnormality, medium leakage and the like occur in a chemical pipeline, the pipeline can be rapidly cut off or connected, and the danger is prevented from spreading.
