Anonymous users2024-01-24Submarines generally have 2 toilets, above and under water. The danger of going to the water toilet is that it is forgotten by the comrades when diving and is "left on it"; The danger of the underwater toilet is relatively greater, because it is necessary to operate the pressure valve (blowing out the dirt, etc.), once the operation sequence is wrong, reverse injection will occur, commonly known as "sitting jet", which will be ridiculed by comrades-in-arms for a lifetime Besides, this kind of reverse injection is not good to sink the ship, which is more dangerous and sloppy.
There are two types of toilets on submarines: above and below, with water toilets being used in a floating state and underwater toilets vice versa. The use of the toilet is closely related to the operation of the submarine, for this reason, the use of the underwater toilet is strictly clear in the regulations, for example, the submarine is prohibited from being used in the process of floating and diving, so as to prevent the submarine from rolling when the toilet is used to discharge the pressure air; It cannot be used in the combat zone to prevent the discharge of air bubbles to expose identity. The use of the underwater toilet is very cumbersome, when entering the toilet, first step on a pedal fixed on the urinal, check whether there is residual gas in the reservoir, if there is residual gas, open the ship's side valve to exclude, after entering the toilet, open the flushing valve to inject seawater, and then open the front cover of the ship's outboard, unscrew the medium pressure air valve to flush out the dirt, the last toilet to screw the valve six or seven times, in these cumbersome operation process, there is a step to reverse the order, the dirt in the toilet will fly out in the reverse direction under the action of air pressure, The submarine crew made a mistake in going to the toilet, and there was a tragedy in which a captain made a mistake when he went to the toilet, which caused the sea water to pour back, and finally the submarine sank!
