Abstract

The invention discloses an interlock pneumatic control system of a de-slagging gate. The system comprises a gas source and a gas cylinder and also comprises a first pneumatic control valve, a second pneumatic control valve, a first manual valve, a second manual valve, a first stroke switch, a second stroke switch, a third stroke switch, a tee connector and a shuttle valve. The technical solution has the beneficial effects that at positions of cover closing and locking, a function of manual cover opening fails, and two channels of mechanical stroke switch gas valves are adopted, so two-channelgas signals of the first pneumatic control valve can be cut off at the same time; when the air cylinder is moved to an unlocking position, the two-channel mechanical stroke switch gas signals can be triggered at the same time, and only one channel can be used normally; because of the stroke switches and a locking gas loop, a unique gas signal loop for cover closing can be ensured by the shuttle valve; and actions of the air cylinder can be switched by the first pneumatic control valve and the second pneumatic control valve based on pneumatic signals, and the air cylinder at the cover closing position triggers the first stroke switch, so the second manual valve can send a pneumatic signal to the second pneumatic control valve for switching of a locking action and an unlocking action; and structural design is reliable, an operation sequence is unique, and operations are convenient, safe and reliable.

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...
