Wind of coal pulverizer turn -offs baffle control system

The utility model provides a wind of coal pulverizer turn -offs baffle control system, including locking the cylinder, open and close cylinder, valve, limit switch LS1 and the LS4 and the delay relay of connecting rod, locking cylinder. The utility model discloses with the help of the position feedback of the electrified function replacement valve of delay relay's time delay, at the electronic equipment of high -temperature region work, does not reduce equipment trouble and does not rate: reduce artificially the judgement of valve position, prevent that maloperation that the erroneous judgement caused is to the damage of equipment on the spot. 本实用新型提供种磨煤机次风关断挡板控制系统，包括锁紧气缸、启闭气缸、阀门，连杆、锁紧气缸的限位开关LS1和LS4以及延时继电器。本实用新型借助延时继电器的延时带电功能代替阀门的位置反馈，没有在高温区工作的电子设备，减少设备故障率：减少人为对阀门位置的判断，防止误判造成的误操作对就地设备的损坏。
