摘要
目前煤矿井下风门机械闭锁器运行容易损坏,为此设计一种气动闭锁装置。利用风门启闭位置,设计一种两位风压开关,实现两道风门互相闭锁和开门报警。
At present, the mechanical-blocking air door of coal mine is easy to damage,so design of pneumatic blocking device to solve this problem.Using the door open-lose position, to design a two position pneumatic switch,which can achieve two doors pneumatic blocking and opening-door alarm.
