The upper port of the first midstream valve 51 is connected with a second inner pipe 11, the second inner pipe 11 is positioned in the upper lock chamber 7, and the upper end of the second inner pipe 11 is higher than the liquid level of the upper lock chamber 7; the second inner pipe 11 is used to convey the water vapour in the lower lock chamber 8 into the upper lock chamber 7.

The upper end opening of the first downstream valve 61 is connected with a third inner pipe 13, the third inner pipe 13 is positioned in the lower lock chamber 8, the upper end opening of the third inner pipe 13 is higher than the liquid level of the lower lock chamber 8, and the third inner pipe 13 is used for conveying the gas in the high-pressure cabin 3 to the lower lock chamber 8.

Further, a steam output valve 31 is arranged on the high-pressure chamber 3.

The utility model discloses a theory of operation is:

when the water in the upper chamber 7 and the lower chamber 8 is filled to the set highest water level (the highest water level can be defined in the upper chamber 7 and the lower chamber 8 according to the water replenishing amount, namely the position of the maximum liquid level can be filled), but the upper port of the second inner tube 11 is higher than the highest water level of the upper chamber 7, and the upper port of the third inner tube 13 is higher than the highest water level of the lower chamber 8, only the water in the upper chamber 7 can not enter the second inner tube 11, and the water in the lower chamber 8 can not enter the third inner tube 13; the high-pressure chamber 3 is heated, when water in the high-pressure chamber 3 is heated, steam is generated, the steam output valve 31 is opened, the steam is discharged through the steam output valve 31, so that the water level in the high-pressure chamber 3 is reduced, and when the water level reaches the lowest water level. In the first step, the first downstream valve 61 is opened, water vapor enters the water supply pipeline 1 through the water outlet end of the water supply pipeline 1, then enters the lower lock chamber 8 through the third inner pipe 13 through the first downstream valve 61, when the air pressure of the two spaces of the high-pressure chamber 3 and the lower lock chamber 8 reaches a balance, the second downstream valve 62 is opened, at the moment, the water in the lower lock chamber 8 is discharged into the high-pressure chamber 3 through the second downstream valve 62 (the main principle is that the water falls into the high-pressure chamber 3 due to the gravity of the water), and then the water replenishing work of the high-pressure chamber 3 is completed.

After the water in the lower lock chamber 8 is emptied, first, the first downstream valve 61 and the second downstream valve 62 are closed, the first midstream valve 51 is opened, the water vapor in the lower lock chamber 8 enters the upper lock chamber 7 through the first midstream valve 51 through the second inner tube 11, when the air pressures in the two spaces of the upper lock chamber 7 and the lower lock chamber 8 reach equilibrium, the second midstream valve 52 is opened, and at this time, the water in the upper lock chamber 7 is injected into the lower lock chamber 8 through the second midstream valve 52 (the main principle is that the water falls into the lower lock chamber 8 due to the gravity of the water), and the water replenishing work in the lower lock chamber 8 is completed.

When the water in the upper lock chamber 7 is emptied, the first midstream valve 51 and the second midstream valve 52 are firstly closed, the first upstream valve 41 is opened, the water vapor in the upper lock chamber 7 enters the normal pressure water tank 2 through the first upstream valve 41, when the air pressures of the two spaces of the upper lock chamber 7 and the normal pressure water tank 2 reach balance, the second upstream valve 42 is opened, and at the moment, the water in the normal pressure water tank 2 is injected into the upper lock chamber 7 through the second upstream valve 42 (the main principle is that the water falls into the upper lock chamber 7 due to the gravity of the water), and the water replenishing work in the upper lock chamber 7 is completed.

The normal pressure water tank 2 can be communicated with a tap water pipe to keep continuous water source injection, and when water in the normal pressure water tank 2 is supplemented, the pressure relief valve 21 must be opened firstly, so that the tap water pipe valve can be opened to supplement water when the pressure in the normal pressure water tank 2 is reduced to the normal pressure level.

In order to ensure that the water replenishing work of each section is orderly and smoothly implemented, the high-pressure chamber 3, the upper lock chamber 7, the lower lock chamber 8 and the normal-pressure water tank 2 are respectively provided with monitoring of upper limit water level and lower limit water level (for example, the upper limit water level and the lower limit water level can be defined according to the water replenishing requirement in the high-pressure chamber 3, water level sensors can be placed on the upper limit water level and the lower limit water level, when the water level is lower than the upper limit water level or the lower limit water level, the water level sensors can control a circuit board to give out alarm lamp signal warning, and the description is omitted herein because the water level sensors, the circuit board and the like belong to the conventional means of technicians in the field in the implementation principle), so that the whole water supply system timely implements or stops the water replenishing work of the corresponding section.

The above processes can be repeatedly circulated, and the water replenishing work for the high-pressure cabin 3 for many times can be completed.

The highest water level in the normal pressure water tank 2 needs to be lower than the upper end of the first inner pipe 9, and a tap water pipe can be connected to the normal pressure water tank 2 to keep the continuous supply of the water source. Similarly, the maximum water levels of the upper chamber 7 and the lower chamber 8 need to be lower than those of the second inner pipe 7 and the third inner pipe 8

In the working process of the chinese invention patent CN106338059B, because the first inner tube 9, the second inner tube 11 and the third inner tube 13 are arranged in the downward direction of one channel in each stage of gate valve, in the working process, the inside of each inner tube can have the condition of coexistence of steam and water, which can result in poor water replenishing efficiency; and this application upwards sets up through first inner tube 9, second inner tube 11, third inner tube 13, can effectively part the route of vapour and liquid, improves the efficiency of moisturizing.

Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications and substitutions are included in the scope defined by the claims of the present application.
