Monitoring shell 1 lateral wall is transparent setting, and monitoring shell 1 lateral wall is provided with the scale mark, makes things convenient for operating personnel to accurately obtain the liquid level height of boiler 15.
A first piston 2 is interference fitted in the monitoring housing 1. Two limiting rods 14 are vertically arranged between the inner top wall and the inner bottom wall of the monitoring shell 1, and the two limiting rods 14 penetrate through the first piston 2 in a sliding mode. The limiting rod 14 can limit the movement of the first piston 2, so that the first piston 2 can only move vertically, and the first piston 2 is prevented from being obliquely clamped or leaking air between the first piston 2 and the inner wall of the monitoring shell 1.
The top of the monitoring shell 1 is fixedly connected with an upper shell 3, and water exists in the upper shell 3. The side wall of the boiler 15 is fixedly connected with a lower shell 4. A connecting cylinder 5 is fixedly arranged between the upper half part of the lower shell 4 and the bottom of the monitoring shell 1, and a liquid discharging part 6 is arranged in the connecting cylinder 5.

The bottom wall in the upper chamber 61 is provided with a lower chamber 62, and the cross section projection of the lower chamber 62 is positioned in the cross section projection in the upper chamber 61.
A second piston 63 is in interference fit in the upper half part of the lower cavity 62, and a first spring 64 is arranged between the top of the second piston 63 and the inner top wall of the upper cavity 61. When the liquid level in the boiler 15 is in a normal state, the first spring 64 is in a natural state, and the upper half part of the second piston 63 is positioned in the upper cavity 61. The elastic force of the first spring 64 is greater than the frictional force between the second piston 63 and the inner wall of the lower chamber 62.
The top wall in the upper chamber 61 is provided with a plurality of upper holes 65, and the upper holes 65 are communicated with the monitoring shell 1. The bottom wall of the lower cavity 62 is provided with a plurality of lower holes 66, and the lower holes 66 are communicated with the lower shell 4.
When the liquid level of the boiler 15 rises, the buoyancy of the water surface pushes the first piston 2 to rise, the lower half part of the monitoring shell 1 forms negative pressure, the negative pressure drives the second piston 63 to rise, the first spring 64 is compressed until the second piston 63 completely enters the upper cavity 61, and the water in the monitoring shell 1 enters the lower shell 4 through the upper hole 65, the upper cavity 61, the lower cavity 62 and the lower hole 66, so that the liquid level in the boiler 15 gradually decreases, and the first spring 64 gradually drives the second piston 63 to restore to the original position.

When the liquid level of the boiler 15 drops, the first piston 2 drops, negative pressure is formed on the upper half part of the monitoring shell 1, the negative pressure pulls the third piston 92 to move, and the second spring 91 extends. Until the third piston 92 moves to one side of the first pipe 7 and the second pipe 8, the first pipe 7 is communicated with the second pipe 8, and the water in the first pipe 7 enters the boiler 15 through the second pipe 8, so that the liquid level of the boiler 15 rises.
When the liquid level of the boiler 15 rises, the third piston 92 moves towards the direction of the second spring 91, in the process, the third piston 92 always shields the bottom of the first pipe 7 and the top of the second pipe 8, and water in the upper shell 3 cannot enter the boiler 15. When the liquid level of the boiler 15 is lowered, the second piston 63 is lowered, and the second piston 63 is always positioned in the lower chamber 62, the water in the monitoring case 1 cannot enter the lower case 4.

When the liquid level in the upper shell 3 is lower, the liquid level sensor 12 transmits information to the controller, and the controller controls the alarm 13 to give an alarm to remind an operator of adding water into the upper shell 3 in time.
The implementation principle of the above embodiment is as follows:
when the liquid level of the boiler 15 rises, the buoyancy of the water surface pushes the first piston 2 to rise, on one hand, the air pressure in the upper half part of the monitoring shell 1 is increased, and the third piston 92 is pushed to move towards the direction of the second spring 91, in the process, the third piston 92 always shields the bottom of the first pipe 7 and the top of the second pipe 8, and water in the upper shell 3 cannot enter the boiler 15; on the other hand, negative pressure is formed at the lower half part of the monitoring shell 1, the negative pressure drives the second piston 63 to rise, the first spring 64 is compressed until the second piston 63 completely enters the upper cavity 61, and water in the monitoring shell 1 enters the lower shell 4 through the upper hole 65, the upper cavity 61, the lower cavity 62 and the lower hole 66, so that the liquid level in the boiler 15 is gradually reduced.
When the liquid level of the boiler 15 is reduced, the first piston 2 is naturally reduced, on one hand, the air pressure of the lower half part of the monitoring shell 1 is increased, the second piston 63 is pushed to be reduced, the second piston 63 is always positioned in the lower cavity 62 in the process, and water in the monitoring shell 1 cannot enter the lower shell 4; on the other hand, a negative pressure is generated in the upper half of the monitoring case 1, and the negative pressure pulls the third piston 92 to move, and the second spring 91 expands. Until the third piston 92 moves to one side of the first pipe 7 and the second pipe 8, the first pipe 7 is communicated with the second pipe 8, and the water in the first pipe 7 enters the boiler 15 through the second pipe 8, so that the liquid level of the boiler 15 rises.
Therefore, the device can automatically treat the rising and the falling of the liquid level in the boiler 15, and the liquid level in the boiler 15 is kept in a proper range.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
