Embodiment 1
[0034] like figure 1 As shown, this embodiment provides an intelligent fire protection control system for an electric valve for a transformer, which includes a valve 1, a driving device 4, a control module 20, a detection module 10, a central control module 30 and a wireless remote control module 40. The control module 20 is respectively connected with The driving device 4, the detection module 10, the central control module 30 and the wireless remote control module 40 are connected. The detection module 10 is used to detect the opening degree of the valve 1, and sends the opening degree signal to the control module 20, and the control module 20 sends the detection module 10. The obtained opening degree signal is processed as a feedback signal and sent to the central control module 30 and the wireless remote control module 40 respectively. The central control module 30 or the wireless remote control module 40 processes the manually inputted opening degree as a control signal an...

The invention relates to the technical field of valves, and discloses an intelligent fireproof control system and method for an electric valve for a transformer, and the system comprises a valve, a driving device, a fireproof device, a control module, a detection module, a central control module and a wireless remote control module. The control module is respectively connected with the driving device, the detection module, the central control module and the wireless remote control module. According to the valve control system, the function of remotely controlling the valve is achieved, and when a transformer accident occurs, a person does not need to go to the site in person or find the accident in the distance, the valve can be rapidly opened through the central control module or the wireless remote control module, and oil can be discharged in time. And meanwhile, when the transformer breaks out of fire due to accidents, flames and high temperature can be effectively isolated within a certain period of time by installing the fireproof device on the valve, so that the electric valve is not influenced by flame combustion in the combustion stage, and normal work can be kept.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to an intelligent fire prevention control system for electric valves used in transformers. Background technique [0002] Valve, the standard GB / T21465-2008 "Valve Terminology" is defined as: the overall structure of the movable mechanical product used to control the medium in the pipeline. The valve should generally be installed horizontally in the pipeline. The main categories of valves are: hydraulic or pneumatic valves, electric valves, manual valves. Among them, the electric valve is an important actuator in the industrial automation control system. The electric valve is a valve that rotates around the axis of the valve stem according to the movement of the valve disc. The change of the valve seat port is proportional to the valve disc stroke. It is mainly used to cut off or connect the medium in the pipeline, and can also be used for the regulation and control of the fluid. ...
