Problems solved by technology
[0002] With the traditional steam engine heating structure, when the heating is completed, the pipeline from the valve switch to the steam rod is at high temperature, so the pressure in this pipeline will be lower than the external pressure, and the steam rod will not be removed in time. The liquid will slowly be sucked back into this section of the pipeline, which will cause damage to the valve switch and cause food safety hazards. Moreover, when the steam rod heats the liquid, the steam vibrates greatly, resulting in a large vibration of the steam pipeline. This leads to damage to the pipeline, and because the steam nozzle cannot move, the heating position is relatively single, which makes the heating speed of the heated liquid slower and affects the efficiency of liquid heating

The invention discloses a steam pipeline mechanism capable of preventing back suction. The mechanism comprises a steam container and a plurality of straight joints, wherein a plurality of connecting pipes distributed in an annular array are fixedly mounted at the upper end of the steam container, bent joints are fixedly connected to the upper ends of the connecting pipes, and first connecting pipes are fixedly mounted at the other ends of the bent joints. Through an arranged exhaust assembly, when a valve switch is turned off, no steam passes through a connecting block, a push block falls down due to the weight, and at the moment, gas enters a water receiving box through a gas inlet hole and then enters the connecting block through a vent hole, and therefore, the air pressure in the connecting block is the same as the external air pressure, and thus, a phenomenon that a liquid heated by a steam faucet is sucked back due to different air pressures in a fourth connecting pipe is prevented, the sucked-back liquid is prevented from entering a second connecting pipe to abut against the valve switch, the valve switch is prevented from being damaged, and potential safety hazards of food are eradicated.
Description
technical field [0001] The invention relates to the technical field of steam pipelines, in particular to an anti-suckback steam pipeline mechanism. Background technique [0002] With the traditional steam engine heating structure, when the heating is completed, the pipeline from the valve switch to the steam rod is at high temperature, so the pressure in this pipeline will be lower than the external pressure, and the steam rod will not be removed in time. The liquid will slowly be sucked back into this section of the pipeline, which will cause damage to the valve switch and cause food safety hazards. Moreover, when the steam rod heats the liquid, the steam vibrates greatly, resulting in a large vibration of the steam pipeline. This results in damage to the pipeline, and because the steam nozzle cannot move, the heating position is relatively single, making the heating of the heated liquid slower and affecting the efficiency of liquid heating.
