When the interior of the living cabin of the saturated submersible is in any one of a pressurization state, a pressure stabilization state and a decompression state, divers in the living cabin can obtain required fresh water by opening/closing the valves in the living cabin (personnel outside the living cabin can open/close the valves outside the living cabin), and then the system can be automatically started/stopped; the mixer and the distributor are both made of stainless steel.
On the basis of the technical scheme, in order to achieve the convenience of use and the stability of equipment, the invention can also make the following improvements on the technical scheme:
further, a safety valve is arranged on the water storage tank.
Further, a thermometer is installed on the mixer.
Further, a pressure sensor, a pressure gauge and a temperature sensor are mounted on the distributor. The pressure sensor is used for detecting the pressure of the system and displaying the pressure on the control panel, and meanwhile, a locally displayed pressure gauge is arranged on the distributor.
Further, the distributor is provided with a pressure switch on a water supply pipe of the living cabin, and the pressure switch is positioned between the distributor and a check valve on the water supply pipe. The pressure switch is closed when the pressure in the living cabin is higher than the system pressure, and is opened when the pressure in the living cabin is lower than the system pressure.
Further, a stop valve A and a check valve A are arranged on a pipeline of the high-pressure pump group to the distributor. The check valve A can prevent the impact on the system caused by overhigh pressure in the living cabin and protect system components and instruments.
Furthermore, a set of standby high-pressure pump set is also arranged.
The invention has the advantages that: this application is rational in infrastructure, and convenient operation can accomplish the required fresh water of the interior dive personnel of living cabin through the temperature controller setting of the cold water pipeline of design and the hot water pipeline mixture.
