Description

Technical Field

[0001] This utility model relates to the field of filling hose technology, and in particular to a novel high-pressure gas filling main hose. Background Technology

[0002] In the field of gas filling, a connection is needed between the high-pressure gas pipeline and the automatic filling system. Since the automatic filling platform needs to be raised and lowered during use, this connection needs to be flexible and able to withstand high pressure. As this connection is part of the main pipeline connection, the inner diameter of the flexible hose needs to reach a certain value to ensure the flow rate of high-pressure gas and achieve high efficiency in automatic gas filling.

[0003] Currently, most high-pressure gas filling hoses on the market have a small inner diameter, resulting in insufficient gas flow and low gas filling efficiency. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel high-pressure gas filling main hose.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel high-pressure gas filling main hose includes a hose connector, to which a fluoropolymer (F46) inner tube is connected. An aramid layer is provided on the outer side of the F46 inner tube. A double-layer stainless steel wire braided mesh is installed on the aramid layer. A breathable rubber layer is provided on the outer side of the double-layer stainless steel wire braided mesh. A stainless steel sheath is also provided on the hose connector, and the stainless steel sheath is connected to the outer side of the breathable rubber layer.

[0007] Preferably, a plurality of anti-swing rope fixing clamps are arranged on the outer side of the breathable rubber layer, and stainless steel anti-swing ropes are connected between the plurality of anti-swing rope fixing clamps.

[0008] Preferably, both ends of the fluoropolymer 66 inner tube are equipped with hose connectors, and each hose connector has a drilled hole. The end of the stainless steel anti-swing rope passes through the drilled hole and wraps back to one side of the stainless steel anti-swing rope. An aluminum sleeve is fixedly connected between the stainless steel anti-swing rope and the end.

[0009] Preferably, one end of the hose connector has an internal thread, and the other end is pagoda-shaped. The fluoropolymer 66 inner tube is connected to the pagoda-shaped end, and the inner diameter of the fluoropolymer 66 inner tube is 13mm.

[0010] Preferably, the aramid layer is wrapped around the outer layer of the fluoropolymer inner tube, the double-layer stainless steel wire mesh is spirally woven on the outside of the aramid layer, the breathable rubber layer is wrapped around the outside of the double-layer stainless steel wire mesh, and the breathable rubber layer has vent holes arranged on the rubber layer.

[0011] Preferably, stainless steel protective springs are installed on both ends of the hose connector, and the hose connector is also provided with threads. The stainless steel protective springs are screwed onto the hose connector and are located on the outside of the hose connector and the breathable rubber layer.

[0012] The beneficial effects of this utility model are:

[0013] This solution uses an aramid layer, a double-layer stainless steel wire braided mesh, and a breathable rubber layer to pressurize the inner tube of fluorocarbon 6, thereby increasing the gas delivery flow rate. The rubber layer has vent holes to prevent gas bulging. The stainless steel anti-spin rope prevents the hose joint from falling off and being ejected by the high-pressure gas. The stainless steel protective spring reduces excessive bending of the hose joint.

[0014] This solution reduces the occurrence of insufficient gas flow during high-pressure gas filling, lowers the risk factor caused by the hose during high-pressure gas filling, increases the inner diameter of the high-pressure gas filling hose, and makes it more stable and less prone to breakage during the filling process. It also increases the gas flow rate during the filling process, thereby accelerating other filling efficiencies. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example: Refer to Figure 1-3A novel high-pressure gas filling main hose includes a hose connector 1, a fluoropolymer hexafluoride inner tube 7 connected to the hose connector 1, an aramid layer 10 on the outside of the fluoropolymer hexafluoride inner tube 7, a double-layer stainless steel wire braided mesh 8 installed on the aramid layer 10, a breathable rubber layer 5 on the outside of the double-layer stainless steel wire braided mesh 8, a stainless steel sheath 2 on the hose connector 1, the stainless steel sheath 2 connected to the outside of the breathable rubber layer 5, and multiple anti-swing rope fixing clamps 4 arranged on the outside of the breathable rubber layer 5, with stainless steel anti-swing ropes 3 connected between the multiple anti-swing rope fixing clamps 4.

[0021] Specifically, both ends of the fluorocarbon inner tube 7 are equipped with hose connectors 1, and each hose connector 1 has a drilled hole. The end of the stainless steel anti-swing rope 3 passes through the drilled hole and wraps back to one side of the stainless steel anti-swing rope 3. An aluminum sleeve 9 is fixedly connected between the stainless steel anti-swing rope 3 and the end. The stainless steel anti-swing rope 3 is mainly used to prevent the hose connector 1 from falling off during use and will not be thrown out under high pressure, causing injury to personnel.

[0022] Furthermore, one end of the hose connector 1 is threaded internally, and the other end is pagoda-shaped. The fluoropolymer 66 inner tube 7 is connected to the pagoda-shaped end. The inner diameter of the fluoropolymer 66 inner tube 7 is 13mm. The fluoropolymer 66 inner tube 7 has high temperature and low temperature resistance. It can still maintain high flexibility at a low temperature of -90°C. It has high corrosion resistance and hardly reacts with other chemical substances at high temperatures.

[0023] Furthermore, the aramid layer 10 is wrapped around the outer layer of the fluoropolymer 10 inner tube 7. Aramid fibers have high wear resistance. Adding the aramid layer 10 between the double-layer stainless steel wire mesh 8 and the fluoropolymer 10 inner tube 7 can effectively protect the fluoropolymer 10 inner tube 7 and greatly improve its service life. The double-layer stainless steel wire mesh 8 is spirally woven on the outside of the aramid layer 10, and the breathable rubber layer 5 is wrapped around the outside of the double-layer stainless steel wire mesh 8. The tightly woven double-layer stainless steel wire mesh 8 tightly wraps the fluoropolymer 10 inner tube 7, allowing it to withstand high pressures of over 35 MPa. Under long-term high pressure, the fluoropolymer 10 inner tube 7 does not deform. The breathable rubber layer 5 has vent holes arranged on its rubber layer to prevent gas bulging.

[0024] In this embodiment, stainless steel protective springs 6 are installed on both ends of the hose connector 1. The hose connector 1 is also provided with threads. The stainless steel protective springs 6 are screwed onto the hose connector 1. The stainless steel protective springs 6 are located on the outside of the hose connector 1 and the breathable rubber layer 5, and mainly serve to protect the connection of the hose connector 1 from being bent significantly.

[0025] Working principle: During the operation of the hose, gas is transported within the fluoropolymer 6 inner tube 7. When the pressure of the transported gas is high, the gas transport is more stable due to the aramid layer 10, the double-layer stainless steel wire braided mesh 8, and the breathable rubber layer 5. The fluoropolymer 6 inner tube 7 is not prone to rupture. During long-term use, the stainless steel protective spring 6 protects the connection between the hose and the hose connector 1, reducing excessive bending that could cause the hose connector 1 to detach. If the hose connector 1 detaches and is ejected by gas after a long period of time, the stainless steel anti-spin rope 3 will pull the hose connector 1 in place, reducing the risk factor.
