In the present embodiment, a cavity 101 is formed between the water seal 10 and the water-cooled tank 20, and when the steam trap is used, media are contained in both the cavity 101 between the water seal 10 and the water-cooled tank 20, so that steam introduced through the steam pipe 30 can be directly introduced into the water seal 10.

The end of the steam pipe 30 inserted into the water seal 10 is connected with a guide member 31, and the guide member 31 can guide the steam introduced by the steam pipe 30 to the cavity 101 and exhaust the air from the opening of the water seal 10. The interface of the collecting pipe 40 connected with the water seal 10 is arranged at the position close to the opening of the water seal 10, so that the medium contained in the steam can be discharged from the collecting pipe 40 after the medium is merged in the cavity 101 and accumulated to a certain amount. The steam pipe 30 of the present embodiment is connected to and communicates with a pipe of the facility at one end extending out of the water-cooled tank 20.

It can be understood that when the steam pipe 30 leads the steam communicated with the pipeline into the water seal 10, the pressure of the medium contained in the water seal 10 needs to be overcome, so that the pressure of the steam conducted in the steam pipe 30 can be led into the water seal 10 only when the pressure of the medium in the water seal 10 is exceeded, and therefore, the steam trap of the present embodiment can be used in place of a trap.

In the present embodiment, the bottom plate 21 of the water-cooled tank 20 of the present embodiment is formed in a hollow structure so that the medium in the water-cooled tank 20 can communicate with the water seal 10 through the hollow bottom plate 21. That is, the medium introduced into the water seal by the steam pipe 30 of the present embodiment needs to overcome the pressure of the medium in the water-cooling tank 20 plus the pressure of the portion of the water seal 10 located at the opening of the steam pipe 30.

As a preferred mode of the present invention, the steam trap of this embodiment further includes a steam isolation pipe 50, the steam isolation pipe 50 is sleeved on the steam pipe 30, and a gap is formed between the steam pipe 50 and the steam pipe 30, so that the steam that is conducted in the steam pipe 30 is prevented from conducting heat to the medium in the water cooling tank 20 in the process of passing through the water cooling tank 20, and thus the steam trap during operation is influenced, and the preset pressure of the steam is introduced.

The guide 31 of the present embodiment is disposed between the bottom of the water seal 10 and the bottom of the water-cooled tank 20, and guides the steam introduced by the steam pipe 30 to the position of the cavity 101 formed by the water seal 10 and the water-cooled tank 20, thereby preventing the steam introduced by the steam pipe 30 from being introduced into the water-cooled tank 20 through the bottom of the water-cooled tank 20.

Specifically, the guiding element 31 of the present embodiment is disposed at the outer periphery of the steam pipe 30, wherein the guiding element 31 has an arc-shaped guiding surface, and the steam introduced from the steam pipe 30 can flow upwards along the arc-shaped guiding surface of the guiding element 31 and enter the cavity 101 formed by the water seal 10 and the water cooling tank 20.

Here, the outer edge of the guide 31 of the present embodiment is disposed outside the upper cavity wall of the water cooling tank 20, so that the steam introduced into the water seal 10 in the steam pipe 30 can flow into the cavity 101 under the guidance of the guide 31.

Further, the bottom of the water-cooled tank 20 of the present embodiment is provided with a closing portion 22, and the outer diameter of the closing portion 22 is gradually reduced toward the guide 31, so that the bottom plate 21 for preventing the steam guided by the guide 31 from flowing toward the water-cooled tank 20 is provided.

In the present embodiment, the connection port 41 of the collecting pipe 40 of the present embodiment, which is communicated with the water seal 10, is provided with a position close to the liquid level of the medium in the cavity 101, so that the medium contained in the steam introduced into the water seal 10 from the steam pipe 30 can be directly collected by the collecting pipe 40. It should be noted that, of course, the connection port 41 for connecting the collecting pipe 40 to the water seal 10 may be disposed at a position higher than the liquid level of the medium, which will not be described herein.

Note that, in the present embodiment, the center line on the water-cooled tank 20 and the center line on the water seal 10 are provided on the same straight line, and the opening of the water seal 10 and the opening of the water-cooled tank 20 are provided on the same plane.

To sum up, the utility model provides a steam hydrophobic means, by the leading-in steam of steam pipe can directly leading-in to the water seal ware in, and under the guide of guide, the appearance chamber between flow direction water seal ware and the water-cooling jar, make the medium that holds the intracavity can be merged into to some medium that steam contains, and collect by the collecting pipe, and do not melt in the steam and outwards get rid of in the opening of water seal ware can be followed to the gas of medium, make this steam hydrophobic means can replace the trap to use, and reach the recovery of containing the medium in to steam, the effect that has saving production resource.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
