Strength of bus door valve
The closing force of the bus is about 30kg.
When the bus is closed, it is usually closed by the hydraulic pressure of the hydraulic rod. In order to prevent people from being injured when closing the door, the outlet pressure of the hydraulic rod will be adjusted to about 30 kg, so that even people who are caught will not be too painful. However, in order to prevent the door from opening automatically when it is closed, which will cause danger to passengers, the pressure of the door is kept at 30kg for a long time after it is closed.
