It also includes a liquid level sensor 6 and a sealing assembly; the liquid level sensor 6 is installed on the condensate tank 1; the sealing assembly is connected inside the condensate tank 1; the sealing assembly consists of a sealing disc 8, a round tube 9, a fixing frame 10, a round rod 11 and a buoyancy plate 12; the sealing disc 8 is fixedly connected inside the condensate tank 1; two fixing frames 10 are fixedly connected inside the condensate tank 1; both fixing frames 10 are located below the sealing disc 8; the round rod 11 is slidably connected inside the two fixing frames 10; the round tube 9 passes through the sealing disc 8; the buoyancy plate 12 is fixedly connected to the lower part of the round rod 11.
[0019] It also includes an electromagnetic vent valve 7; the condensate tank 1 is connected to the electromagnetic vent valve 7.
[0020] It also includes a top cover 101 and fixing bolts 103; the condensate tank 1 consists of a tank body and a top cover 101; the top cover 101 is detachably connected to the tank body; the tank body and the top cover 101 are connected together by fixing bolts 103.
[0021] It also includes lifting rings 102; several symmetrical lifting rings 102 are fixedly connected to the top cover 101.
[0022] It also includes a sealing ring 104; the sealing ring 104 is connected to the lower side of the upper cover 101; and a sealing groove that mates with the sealing ring 104 is provided on the tank body of the condensate tank 1.
[0023] The sealing ring 104 is a hollow structure, and the sealing ring 104 contains gas that expands and contracts with temperature.
[0024] The sealing disc 8 is made of corrosion-resistant material, which improves the service life of the sealing disc 8.
[0025] The buoyancy disk 12 is made of corrosion-resistant buoyancy material, which improves the service life of the buoyancy disk 12.
[0026] Several drainage grooves 1102 are provided on the round rod 11.
[0027] The lower part of the round rod 11 is set as a hollow structure, and several water inlet holes 1101 connected to the hollow structure are opened on the round rod 11; an electromagnetic drain valve 13 is provided at the bottom of the round rod 11, and the electromagnetic drain valve 13 is connected to the hollow part of the round rod 11.
[0028] During installation, the top cover 101 is hoisted using lifting rings 102 and fixed to the tank body of the condensate tank 1 using fixing bolts 103. A sealing ring 104 ensures a tight seal at the connection between the top cover 101 and the tank body. During use, steam is introduced into the condensate tank 1 through steam pipe 4, and a vacuum is created by connecting an external vacuum pump through vacuum pipe 3. The steam condenses into water inside the condensate tank 1 and collects on the sealing plate 8. The condensate is then guided to the lower part of the condensate tank 1 through a circular pipe 9, and monitored by a liquid level sensor 6. The condensate level in condensate tank 1 is measured. When the condensate level reaches the height of the buoyancy plate 12, the buoyancy causes the buoyancy plate 12 to drive the round rod 11 to slide upward within the fixed frame 10 as the condensate level rises. As the round rod 11 rises, it inserts into the round tube 9. At this time, the condensate on the sealing plate 8 flows into the lower part of the condensate tank 1 through the drain trough 1102 until the drain trough 1102 is completely above the round tube 9. At this point, the condensate level is at the threshold monitored by the level sensor 6. The drain pipe 5 and the solenoid vent valve 7 are opened, allowing the condensate collected at the bottom of the condensate tank 1 to be automatically discharged and collected through the drain pipe 5. The condensate on the sealing plate 8 is introduced into the hollow structure at the bottom of the round rod 11 through the inlet hole 1101 for collection. Due to the vacuum effect at the top of the condensate tank 1 and the external atmospheric pressure, the round rod 11 is held inside the round tube 9, and the buoyancy plate 12 does not descend with the drop in condensate level. This, in turn, creates a seal through the cooperation of the round rod 11 and the round tube 9, achieving automatic monitoring and discharge of condensate in the condensate tank 1. Simultaneously, it avoids disrupting the vacuum effect of the condensate tank 1 during drainage. The sealing is achieved through a simple structure of the round rod 11 and the round tube 9, eliminating the need for a precision electronic valve body for control. This avoids the frequent damage and failures caused by steam erosion of the precision electronic valve body. After the condensate is drained, the drain pipe 5 and the solenoid vent valve 7 are closed. At this time, the round rod 11 slides down and automatically resets itself within the fixing frame 10 due to its own weight and the weight of the condensate collected inside the round rod 11. After the round rod 11 and the buoyancy plate 12 are reset, the solenoid drain valve 13 is opened to drain the condensate collected inside the round rod 11. Then the solenoid drain valve 13 is closed to ensure the buoyancy plate 12 floats up effectively the next time.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
