| Zusammenfassung: | The utility model provides an evaporate boiler utensil voltage limiting pressure relief device and evaporate boiler utensil. Boiler utensil voltage limiting pressure relief device be should evaporateand pedestal and voltage limiting were included physically be provided with airflow channel in the pedestal be provided with the voltage limiting hole on the pedestal, the voltage limiting physical stamina enough is in the lower motion of gas pressure action in the airflow channel is in order to incite somebody to action airflow channel with communicate or cut off between the voltage limiting hole, still be provided with on the pedestal with the pressure release hole and the general of airflow channel intercommunication pressure release hole confined pressure release spare. The utility model provides an evaporate the motion of boiler utensil voltage limiting pressure relief device through the voltage limiting body and can realize the voltage limiting to evaporating the boiler utensil, andbecame invalid or evaporat |
