Abstract
An automatic locking-type purge device comprises a shell, wherein a reversing electromagnetic valve, a propelling air cylinder, a pushing plate, a grooved guide pipe, an L-shaped slide pipe, a metal hose, a locking air cylinder, a quick coupling, a nitrogen electromagnetic valve, an electromagnetic check valve, a connection pipe and a mechanism connection member. The automatic locking-type purge device is characterized in that two groups are controlled by the reversing electromagnetic valve to be reasonably matched with each other to run, and a process for rapidly locking, butt joint and effectively disconnection of the quick coupling can be completed. After the butt joint and the purging are completed, the quick coupling is disconnected, so that the coal gas can be prevented from entering a purge medium pipeline and from being leaked. The automatic locking-type purge device can be matched with a quick disconnection valve to be accessed to a program logic controller (PLC) control system, so that the automatic control of a coal gas pipeline system and a manually-controlled quick purge function can be realized.
