Examples

Aiming at the problem that negative pressure fluctuation or flooding of a system is easily caused during liquid drainage when errors or electrical faults occur through manual operation in the existing negative pressure state, the invention provides an automatic condensate discharging structure in the negative pressure state, which is specifically as shown in fig. 1, and comprises a discharging pipeline 2, wherein the discharging pipeline 2 is a U-shaped pipe, the U-shaped pipe comprises a first pipe section 21, a second pipe 22 and a third pipe section 23, the first pipe section 21 is connected with a condensate device 1, the first pipe section 21 and the third pipe section 23 are arranged in the vertical direction, and the length of the first pipe section 21 is greater than that of the third pipe section 23. The discharge pipeline 2 is a U-shaped pipe, the first pipe section 21 in the U-shaped pipe is longer than the third pipe section 23, and the first pipe section 21 is connected with the condensate device 1, so that a liquid level difference exists in the U-shaped pipe, the liquid accumulated in the first pipe section 21 flows into the third pipe section 23 through the second pipe section 22, and the liquid flowing into the third pipe section 23 is automatically discharged due to the liquid level difference, so that the condensate in the condensate device 1 is automatically discharged, and meanwhile, the U-shaped pipe is filled with the condensate, so that a liquid seal effect can be achieved, the condensate device 1 is in a closed state, and the negative pressure of the system is maintained, so that the discharge structure can prevent the condensate from being sucked back into the upper-end condensate device 1 under the condition of the negative pressure, and can achieve stable, continuous and automatic liquid discharge. Meanwhile, the height difference between the first pipe section 21 and the second pipe section 22 of the U-shaped pipe can be designed and calculated according to the actual negative pressure condition. As in practical conditions, the height difference between the first pipe section 21 and the second pipe section 22 in the U-shaped structure is not less than 0.5m under the condition that the negative pressure of the system is-5 Kpa.

Further, the third pipe section 23 is connected with the liquid discharge pipe 4.

Further, the liquid discharge pipe 4 is an L-shaped liquid discharge pipe, and a liquid discharge port of the L-shaped liquid discharge pipe faces vertically downwards. The above-described drain structure facilitates the collection of condensate.

Further, a drain valve 3 is disposed on the drain pipe 2. The structure is helpful for controlling whether to discharge liquid or not at any time.

Further, the discharge pipe 2 is integrally formed with the drain pipe 4. The forming of the discharge pipe 2 and the liquid discharge pipe 4 is facilitated, and the phenomenon of water leakage at the joint between the two is not easily caused.

Furthermore, the liquid discharge pipeline 2 and the liquid discharge pipe 4 are made of transparent materials. The liquid level in the liquid discharge pipeline 2 and the liquid discharge pipe 4 can be observed conveniently.
