As an example, as shown in fig. 1, an overflow passage 31 is provided between a side wall of the reference cup 3 and a side wall of the second chamber 102 to introduce the remaining water into the second chamber 102 through the overflow passage 31 after the reference cup 3 is filled with water.

It should be noted that, since the volume of the reference cup 3 is limited, the condensed water flows into the second chamber 102 through the overflow passage 31 after filling the reference cup 3.

As an embodiment, as shown in fig. 1, a drain hole 81 is opened on the bottom end cover 12 of the second chamber 102, and the drain hole 81 is connected to the descending drain pipe 8 to drain the collected water in the second chamber 102.

It should be noted that since the lower drainage pipe 8 is connected to the bottom cover 12 of the second chamber 102 and is connected to the downcomer of the boiler, the dynamic force of the fluid passing through the downcomer of the boiler results in substantially no water accumulation or only a small amount of water accumulation in the second chamber 102.

As an embodiment, as shown in fig. 1, a first manual valve is provided on the first connection pipe, a second manual valve is provided on the second connection pipe, and a third manual valve is provided on the descent drain pipe.

After the balance container is installed, when the balance container is debugged for the first time, the first manual valve, the second manual valve and the third manual valve on the balance container are closed, and then the blowdown valve below the meter three-valve group and the exhaust valve of the meter are closed. And then, opening a water filling port plug 71 and a sealing piece 72 of the balance container, after the balance container is filled with water through a water filling hole, opening a drain valve and an exhaust valve of the instrument (the water is filled into the water filling port of the balance container while the drain valve and the exhaust valve of the instrument are opened), and indicating that the pressure guiding pipes of the reference water cup and the instrument do not have water vapor until the drain valve and the exhaust valve discharge water instead of a steam-water mixture. At this point, the instrument blowoff valve and the exhaust valve are closed, and water continues to be injected into the balance container water injection hole until the water overflows the reference cup, at which time the water injection hole is sealed by the water injection port plug 71 and the sealing member 72.

After filling with water in the above manner, the first manual valve is opened to discharge part of the water in the first chamber 101 into the steam drum. And opening the second manual valve to discharge the water in the three-way component into the steam pocket. The third manual valve is opened to drain the water from the second chamber 102 to the boiler downcomer (during which excess water from the second chamber 102 will flow through the condensate funnel 2, the reference cup 3, the overflow channel 31 to the second chamber 102 to drain to the boiler downcomer). Therefore, the requirement of the reference cup 3 for marking the reference height can be met without the condensed water of steam, and the purpose of debugging the instrument is achieved when the equipment does not run to generate steam. In addition, in the operation and maintenance of the balance container equipment, if the balance container needs to be cooled and exhausted, the gas in the balance container can be exhausted by opening the water injection hole, and cooling water is injected to meet the requirement of rapidly cooling the balance container.

As an example, as shown in fig. 1, the first through hole 1011 and the second through hole 63 are disposed on the same sidewall of the cavity, and the third through hole 41 and the fourth through hole 51 are disposed on the same sidewall of the second chamber 102.
