Fig. 1 illustrates a specific embodiment of a quick drain device according to the present invention, and referring to fig. 1, a quick drain device comprises a drain container 100, a drain valve 200 and an industrial controller 300, an inlet 101 of the drain container 100 is connected to a water return port of a steam device (not shown in the drawings) through a water return pipe 400, the drain container 100 is connected to the drain valve 200 through a drain pipe 500, in this embodiment, the drain pipe 500 and the water return pipe 400 are both stainless steel pipes, the other end of the drain valve 200 is connected to a water outlet pipe, the drain container 100 is further provided with a level gauge 600 for measuring a liquid level in the drain container 100, a thermometer 700 for measuring a temperature in the drain container 100 and a pressure gauge 800 for measuring a pressure in the drain container 100, the

level gauges

600 and 700 and the pressure gauge 800 are all electrically connected to the industrial controller 300, in this embodiment, two liquid level meters 600 are disposed on the hydrophobic container 100, the two liquid level meters 600 are respectively a high liquid level meter and a low liquid level meter, the two liquid level meters 600 are both float ball liquid level meters, and the thermometer 700 is a WST-102 digital display bimetal thermometer; the drain valve 200 is also provided with a valve opening switch 900 which is electrically connected with the industrial controller 300 and is used for adjusting the opening of the drain valve 200; in the present embodiment, the drain valve 200 is integrated with the valve opening switch 900 into a regulation type gate valve, which is a model DZW10-24 gate valve.

The drainage apparatus of this embodiment controls the valve opening switch 900 of the drain valve 200 to operate according to the level of the liquid in the drainage container 100 (measured by the liquid level meter 600), and adjusts the opening (two steps) of the drain valve 200 according to the temperature in the drainage container 100 (measured by the thermometer 700), when the temperature is lower than the set temperature (low-pressure low-temperature condensed water) and the liquid level signal is high, the valve opening switch 900 of the drain valve 200 is fully opened to rapidly drain the low-pressure low-temperature condensed water; when the temperature is higher than the set temperature and the liquid level signal is high, the drain valve 200 is in a small opening degree, so that high-temperature condensed water is slowly drained, and steam leakage caused by untimely valve closing (delay of valve operation) due to too fast drainage because the pressure (condensed water pressure and outlet side back pressure) at two ends of the drain valve 200 is too large is avoided.

Compared with the traditional drain valve, the embodiment not only solves the problem of rapid drainage when the amount of condensed water is large, but also ensures no leakage of steam, and achieves the effect of saving steam energy consumption; the embodiment solves the problem that the quality of the traditional trap can not be judged from the appearance when the traditional trap breaks down (is blocked or leaks); the embodiment has the advantages of small fault, convenient maintenance and simple and visual fault judgment, and solves the problems that when a plurality of steam traps are installed on one set of gas equipment in the prior art, the production is influenced by the rising of the back pressure of the whole condensate water, the drainage abnormality of other parts of the whole system and the insufficient equipment temperature caused by the leakage of one steam trap and the difficulty in overhauling and finding the fault.

The above is not intended to limit the technical scope of the present invention, and any modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are all within the scope of the technical solution of the present invention.
