Description

Technical Field

[0002] Teflon stainless steel braided hose is mainly composed of an inner layer of polytetrafluoroethylene hose and an outer layer braided by stainless steel wire, with metal joints installed at both ends. It is suitable for hydraulic, pneumatic, steam transportation and other purposes in multiple industries, including the transportation of alternating hot and cold liquids, gases and various media.

[0003] The existing Teflon stainless steel braided tube still has some problems when in use. First, the outer layer of the existing Teflon stainless steel braided tube is too hard and the inner layer is relatively soft. When subjected to a large force or moved and flipped, the position of the braided tube near the joint is most susceptible to the force of fluid impact and wear, and its durability is low and its service life is reduced. Secondly, when encountering a high temperature environment, the temperature near the joint is high, and the inner hose is also easily damaged after long-term use. The existing heat dissipation is low, which reduces the use effect of the braided tube. Utility Model Content

[0029] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0030] A Teflon stainless steel braided tube provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0031] Embodiment 1:

[0032] Combination Figure 1-Figure 4 As shown, the utility model provides a Teflon stainless steel braided tube,

[0033] Specifically, it includes a braided tube body 1, a first joint 2 and a second joint 3. The braided tube body 1 is respectively composed of a stainless steel braided shell 101 and an inner hose 102. The stainless steel braided shell 101 is sleeved on the outer side of the inner hose 102. A protective sleeve 4 is embedded and connected between the two ends of the stainless steel braided shell 101 and the inner hose 102 near the first joint 2 and the second joint 3. The interior of the protective sleeve 4 is filled with a supporting rubber pad 7. The supporting rubber pad 7 is made of high-temperature resistant silicone material and has high protective wear resistance. The supporting rubber pad 7 is evenly provided with a plurality of mounting slots 8. An elastic extrusion protection component 5 is installed inside the mounting slot 8. The elastic extrusion protection component 5 is respectively composed of a compression airbag 501, an extrusion support sheet 502, a heat-conducting extrusion sheet 503, a metal support spring sheet 504, a porous breathable sheet 505 and a compression through hole 506. The protective sleeve 4 and the extrusion support sheet 502 are connected at one side of the stainless steel braided shell 101, and the extrusion support sheet 502 and the heat-conducting extrusion sheet 503 are respectively installed on the upper and lower ends of the inner side of the protective sleeve 4. The top of the compression airbag 501 is connected to the extrusion support sheet 502, and the bottom end of the compression airbag 501 is connected to the porous breathable sheet 505. The metal support spring sheets 504 are symmetrically arranged on both sides of the compression airbag 501, and the metal support spring sheets 504 are installed between the extrusion support sheet 502 and the heat-conducting extrusion sheet 503. The use of the above-mentioned components, especially the shock-absorbing, protective and wear-resistant effects of the elastic extrusion protection component 5 and the supporting rubber pad 7 in the protective sleeve 4, reduces the wear between the stainless steel braided shell 101 and the inner hose 102 near the first joint 2 and the second joint 3 ports, improves the durability of the braided tube, and extends its service life.

[0034] Embodiment 2:

[0035] Combination Figure 4 As shown, based on the first embodiment,

[0036] Specifically, the porous breathable sheet 505 is embedded and clamped on the top of the heat-conducting extrusion sheet 503, and the compression through holes 506 are opened at the upper and lower ends of the compression airbag 501. The compression airbag 501 is connected with the air holes 9 through the compression through holes 506, and is connected with the installation slot 8 through the abutment with the porous breathable sheet 505. The use of the above-mentioned components, including the function of the elastic extrusion protection component 5 in the first embodiment, makes the compression airbag 501 compressed and stretched under force, and the internal gas is expelled to the outside to dissipate heat, thereby improving the use effect of the braided tube.

[0037] Combination Figure 1 , Figure 2 and Figure 3 As shown, in the above embodiment,

[0038] Specifically, the first joint 2 and the second joint 3 are respectively threadedly embedded and sleeved on the two ends of the braided tube body 1, and sealing plugs 6 are embedded between the inner sides of the first joint 2 and the second joint 3 and the braided tube body 1. The sealing plugs 6 are mainly used to improve the sealing performance of the joints between the first joint 2 and the second joint 3 and the braided tube body 1.

[0039] Specifically, the working principle and use process of the utility model are as follows: first, when in use, the braided tube body 1 is connected to the external interface through the first joint 2 and the second joint 3. When the impact force of the fluid causes the braided tube body 1 to vibrate, the support rubber pad 7 and the elastic extrusion protection component 5 inside the protective sleeve 4 between the stainless steel braided shell 101 and the two ends of the inner hose 102, especially the elastic support stabilization effect of the metal support spring 504 and the compression airbag 501 composed of the elastic extrusion protection component 5, make the extrusion support sheet 502 and the heat-conducting extrusion sheet 503 support the protective sleeve 4, and reduce the wear of the stainless steel braided shell 101 on both sides of the inner hose 102, which not only improves The high durability of the braided tube also improves the overall service life. Secondly, during the above-mentioned use, when the heat generated by the fluid passes through the inner hose 102, the heat-conducting extrusion sheet 503 composed of the elastic extrusion protection component 5 first guides part of the heat guided by the inner hose 102 to the inside of the installation slot 8. When the protective sleeve 4 is vibrated by the impact of the stainless steel braided shell 101 and the inner hose 102 due to the impact of the fluid, the metal support spring 504 and the compression airbag 501 are elastically extruded to compress and stretch, so that the compression through holes 506 at both ends of the compression airbag 501 compress and absorb the heat inside the installation slot 8 through the porous breathable sheet 505 through the air holes 9 and discharge it to the outside, thereby improving the heat dissipation effect and improving the overall use effect.
