1. hydraulic principle:
Support bar chair is made of hydraulic principle! It's like the principle of a car jack. If it is not up, the valve can not be shut down. It's not going to explode in this case!
The explosion occurred mainly because the closed valve inside the hydraulic rod was damaged or the slot was damaged. The internal pressure is too big to lift the lifting rod.
