AI Technical Summary
Existing steam nozzles pose risks of burns, scaling, and steam leaks due to poor sealing, affecting safety and efficiency.
It adopts a three-layer structure consisting of an outer tube, an inner tube, and a Teflon tube. A gap is set between adjacent layers to form a heat insulation layer. Steam flows through the Teflon tube and is tightly connected to the steam pipe and nozzle through a threaded interface. Sealing gaskets and sealing rings are used to fill the gaps to prevent leakage.
It effectively reduces the transfer of heat from high-temperature steam to the outer layer, preventing burns and scaling, ensuring sealed steam delivery, preventing leaks, and improving safety and efficiency.
