Application example 1:

referring to fig. 3 in conjunction with fig. 1 and 2, in fig. 3 there is shown a steam boiler 5, the steam generated by the steam boiler 5 being fed by a main steam line 51 to a steam iron 6 as steam consuming device, and the condensate water generated by the steam iron 6 being led via the invention to a condensate water return line 52 (already mentioned above) of the steam boiler 5. As shown in fig. 3, a main steam pipe steam outlet 511 is provided at an interval in the middle of the main steam pipe 51, and an external screw thread fitting 512 for fitting with the present invention is provided at the end of the main steam pipe 51; a female screw fitting 521 is provided at an interval on the condensate return pipe 52.

Wherein, the valve seat steam-water introducing internal thread 131 of the valve seat 1 of the energy-saving steam automatic trap of the utility model, which is located at the end of the main steam pipeline 51, i.e. the leftmost end of the position state shown in fig. 3, is connected with the external thread matching interface 512 at the end of the main steam pipeline 51, and the valve cover joint 41 of the valve cover 4 is connected with the condensate water return pipe 52 by a pipeline.

Use the utility model discloses automatic trap of energy-conserving steam is connected with steam iron steam return pipe 62 of steam iron 6 for the example, and the steam that the secondary steam in the steam system was come back out by steam iron 6 is by steam iron steam return pipe 62 through valve seat soda introduction hole 13 and valve seat soda introduction hole drill way 133 in proper order. Specifically, with the entry of high-temperature condensed water, secondary steam is generated due to pressure reduction, dynamic pressure rises and static pressure is reduced, and the valve plate 2 moves downwards; meanwhile, the secondary steam enters the upper part of the valve block 2, applies downward pressure to the valve block 2, forces the valve block 2 to close, prevents the steam from flowing out, namely the utility model belongs to the category of the thermal power drain valve and is in a closed state; the heat-driven trap is operated again in a cycle with the condensation of the secondary steam and the increase of the condensed water. More specifically: when the valve plate is started, namely in the use process, under the action of pressure, the valve plate 2 is jacked upwards, condensed water and air are quickly discharged out of the hole 132, after the pressure rises, hot condensed water generates secondary steam when passing through the valve seat 1, the secondary steam moving at high speed generates a low-pressure area below the valve plate 2, so that the valve plate 2 is close to the upper end face of the valve plate seat 111, meanwhile, the secondary steam is accumulated in the space of the valve plate inserting cavity 33 above the valve plate 2, and certain pressure is generated to enable the valve plate 2 to be close to the valve plate seat 111. The valve sheet 2 is then pressed against the upper surface of the valve sheet seat 111, i.e., against the inner ring of the upper portion of the valve seat 1, closing the orifice 132, so that the pressure above the valve sheet 2 can be maintained. Due to the condensation of the secondary steam above the valve plate 2, the pressure drops, the valve plate 2 is jacked up again, the valve plate 2 is opened again, the condensed water can be freely discharged, and the circulation is carried out.

When the valve plate 2 is opened, that is, when the valve plate floats upward, the path of the condensed water is sequentially led back to the condensed water return pipe 52 from the valve plate seat inlet chamber 33, the valve plate seat drain groove 1112, the drain hole 1111, the vapor-liquid accumulation chamber 32, the vapor-liquid guide hole 31, the valve cover water collection chamber 42, the valve cover joint drain hole 411 and the transition connection pipe 5211, and then led back to the steam boiler 5. Since the trap of the present invention connected between the end of the main steam pipe 51 and the condensate water return pipe 52 is the same as the above-mentioned case, it will not be described again.

Application example 2:

referring to fig. 4, the internal thread 131 of the valve seat steam-water inlet hole of the valve seat 1 of the energy-saving automatic steam trap structure of the present invention is directly connected to the steam-returning interface 63 of the steam iron 6, and the rest are the same as those described in the corresponding example 1.

To sum up, the technical solution provided by the present invention remedies the defects in the prior art, successfully completes the invention task, and faithfully embodies the technical effects mentioned in the above technical effect column by the applicant.
