Abstract

The invention discloses a slag door interlock pneumatic control system, which includes an air source and a cylinder, and also includes a first air control valve, a second air control valve, a first manual valve, a second manual valve, and a first travel switch , The second stroke switch and the third stroke switch, the three-way joint and the shuttle valve, the above technical scheme, the closed cover and locked position, the manual open cover function is invalid, in order to ensure that the two air signals of the first air control valve are cut off at the same time, 2-way mechanical stroke switch air valve is adopted; when the cylinder reaches the unlocked position, the 2-way mechanical stroke switch air valve is triggered at the same time, but only one of them can be used normally; the stroke switch and locking air circuit, through the shuttle valve to ensure the only one to close the cover Pneumatic signal circuit; the first air control valve and the second air control valve use air signals to switch the action of the cylinder. When the cylinder is in the position of closing the cover, the first stroke switch is triggered to let the second manual valve send an air signal to the second air control valve. Switching locking and unlocking action of the valve; reasonable structure design, unique operation sequence, convenient operation, safety and reliability.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a slag door interlocking pneumatic control system. Background technique [0002] Existing slag door device is made up of two parts of door cover and rotation lock, and the door cover and rotation lock of drive device are respectively driven by two groups of cylinders. Rotation lock is a safety device to prevent accidents and material loss caused by accidental opening of the door cover. When the equipment is in normal process, the reciprocating action of the cylinder is completed through the manual control valve, see figure 1 , The manual valve 1 has the state of opening and closing the cover, and the manual valve 2 has the state of unlocking and locking. First, the manual valve 2 is unlocked, the revolving door is opened, and then the cover is opened by the manual valve 1, and the cover door is opened. Carry out the waste slag cleaning in the tank body, after proc...
