However, the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0022] Secondly, the so-called "one embodiment" or "embodiment" refers to specific features, structures, or characteristics that may be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that mutually excludes other embodiments. The present utility model provides the following embodiments.
[0023] A high-temperature resistant stainless steel electric heating pressure hose proposed by the present utility model, as Figure 1 and Figure 2 shown, includes a pressure hose main body 9 and two elastic caps 1 symmetrically connected to both ends of the pressure hose main body 9. The outside of the pressure hose main body 9 is wrapped with multiple structural layers. A core corrugated pipe 10 is arranged inside the pressure hose main body 9, and the material of the core corrugated pipe 10 is stainless steel, which is used to improve the heat resistance effect of the pressure hose main body 9 and the service life of the pressure hose main body 9 itself. The structural layers include a braided layer 5, a heat insulation layer 6, a temperature sensor 7, and a heating conduit 8. The heating conduit 8 is spirally wound around the outside of the pressure hose main body 9. The temperature sensor 7 is located between the gaps of the heating conduit 8. The heat insulation layer 6 is provided in two layers outside the heating conduit 8. The braided layer 5 is arranged outside the heat insulation layer 6. The inner layer of the heat insulation layer 6 is thinner and wraps around the outside of the heating conduit 8. The outer layer of the heat insulation layer 6 is thicker and wraps around the outside of the inner layer of the heat insulation layer 6. The material of the heat insulation layer 6 is textile glass, and the textile glass fibers in the heat insulation layer 6 are relatively dense. The material of the braided layer 5 is also textile glass, and the gaps between the textile glass fibers inside the braided layer 5 are relatively large. The core corrugated pipe 10 is a corrugated pressurized hose made of stainless steel.
[0024] In this embodiment, when the substance to be transported enters the inside of the core corrugated pipe 10, the heating conduit 8 can heat the substance to be heated. At the same time, the temperature sensor 7 can detect the actual temperature and transmit it to the outside. The external heat insulation layer 6 can reduce the heat overflow, reduce the heat loss, and also improve the heating effect. Further, the braided layer 5 can also prevent the heat from overflowing. The inner core corrugated pipe 10 is used as the pipeline for the specific transportation of the substance. At the same time, the core corrugated pipe 10 made of stainless steel can withstand a maximum temperature of up to five hundred and fifty degrees Celsius. Thus, the high-temperature resistance performance of the electric heating pressure hose can be greatly improved, and at the same time, the heat-resistant life of the electric heating pressure hose can be made longer, which can greatly improve the practicality of the electric heating pressure hose.
[0025] Refer to Figure 1 and Figure 2 At both ends of the two elastic caps 1 in opposite directions to the core bellows 10, connecting fittings 4 are fixedly installed. A connecting cable 2 is fixedly connected to the outside of one of the elastic caps 1, and a connecting plug 3 is fixedly installed at one end of the connecting cable 2.
[0026] In this embodiment, the feeding end pipeline and the discharging end pipeline can be docked respectively through the connecting fittings 4. At the same time, the connecting plug 3 can connect to the external circuit to supply power to the internal circuit components.
[0027] The working principle of the present utility model is as follows: The feeding end pipeline and the discharging end pipeline can be docked respectively through the connecting fittings 4. At the same time, the connecting plug 3 can connect to the external circuit to supply power to the internal circuit components. When the substance to be transported enters the inside of the core bellows 10, the heating conduit 8 can heat the substance to be heated. At the same time, the temperature sensor 7 can detect the actual temperature and transmit it to the outside. The external heat insulation layer 6 can reduce the heat overflow, reduce the heat loss and improve the heating effect at the same time. Further, the braided layer 5 can also prevent the heat from overflowing. The internal core bellows 10 is used as the pipeline for the specific transportation of the substance. At the same time, the core bellows 10 made of stainless steel can withstand a maximum temperature of up to five hundred and fifty degrees Celsius. Therefore, the high-temperature resistance performance of the electric heating pressure hose can be greatly improved, and at the same time, the heat-resistant life of the electric heating pressure hose can be made longer, which can greatly improve the practicality of the electric heating pressure hose.
