Description

TECHNICAL FIELD

[0001] The present application relates to the field of silica gel tubes and their matching components, and in particular to an absolutely insulated silica gel tube kit. BACKGROUND

[0002] Silica gel tubes, as a tubular product made of silica gel material, play an important role in fluid transmission systems in new energy, hydrogen energy and other fields due to their multiple advantages such as high temperature resistance, corrosion resistance, excellent insulation performance, high elasticity and resilience, physiological inertness, and environmental friendliness. In order to meet the needs of different application scenarios, silica gel tubes are usually designed to have multiple functional characteristics, such as enhanced pressure resistance and installation convenience, to meet increasingly stringent industrial standards and technical requirements.

[0003] In actual applications, in order to improve the strength and pressure resistance of silica gel tubes, the industry generally embeds steel wires or other metal reinforcing materials inside the silica gel tubes. In addition, in order to facilitate installation, flanges are often provided at both ends of the silica gel tube to facilitate its secure connection to various fluid conveying systems. Common methods include but are not limited to the following: one is to embed steel wires inside the silica gel tube through a hot melt process; two is to wrap metal wires outside the silica gel tube using a mechanical method; three is to manufacture flanges and silica gel tubes integrally through injection molding.

[0004] Although the above methods can improve the overall performance of silica gel tubes to some extent, in certain specific application scenarios, especially in environments requiring strict insulation, these traditional design schemes have obvious shortcomings. Specifically, when the silica gel tube is processed, the end faces of both ends will expose steel wires, causing the flanges to come into direct contact with these exposed steel wires. Since both the flanges and the steel wires are conductive, this can cause electrical safety hazards, especially when used in high-voltage or sensitive equipment, which can cause serious safety accidents. Therefore, how to achieve absolute insulation effect in the application of silica gel tubes while maintaining their original excellent performance has become a key technical problem to be solved. CONTENT OF THE INVENTION

[0005] In order to overcome the above technical problems, an absolutely insulated silica gel tube kit is provided.

[0006] The present application provides an absolutely insulated silica gel tube kit, comprising a silica gel tube and two flanges installed at both ends of the silica gel tube, the silica gel tube is provided with at least one first metal reinforcing layer, the two ends of the silica gel tube are respectively provided with an insulating sheet, the insulating sheet is located between the silica gel tube and the flange, and the first metal reinforcing layer does not come into contact with the flange.

[0007] By adopting the technical scheme, the insulating sheet arranged at the two ends of the silica gel pipe can effectively prevent direct contact between the first metal reinforcing layer and the flange, and realize absolute insulation effect. This not only improves the safety performance of the silica gel pipe set, but also enhances the reliability and practicality in actual application, prevents current from being conducted to the flange through the first metal reinforcing layer, and avoids potential electrical safety hazards.

[0008] Preferably, the silica gel pipe is sequentially provided with a first silica gel pipe layer, a second silica gel pipe layer, a first metal reinforcing layer, a third silica gel pipe layer, and a fourth silica gel pipe layer from the outer surface to the inner surface, and the side of the insulating sheet away from the flange is connected with the cross sections of the first silica gel pipe layer, the second silica gel pipe layer, the first metal reinforcing layer, the third silica gel pipe layer, and the fourth silica gel pipe layer.

[0009] By adopting the technical scheme, the silica gel pipe is sequentially provided with a first silica gel pipe layer, a second silica gel pipe layer, a first metal reinforcing layer, a third silica gel pipe layer, and a fourth silica gel pipe layer from the outer surface to the inner surface, so that the entire silica gel pipe has good hierarchical structure and mechanical properties. In particular, the side of the insulating sheet away from the flange is connected with the cross sections of each layer, which not only enhances the connection stability between the insulating sheet and the silica gel pipe, but also effectively prevents the insulating sheet from loosening or mispositioning during long-term use, ensuring that the insulation effect of the silica gel pipe set is durable and reliable.

[0010] Preferably, the second metal reinforcing member is further included, the outer wall of the silica gel pipe is circumferentially recessed with a groove for embedding the second metal reinforcing member, the insulating barrier part is provided on the insulating sheet and extends along the length direction of the outer wall of the silica gel pipe, the side of the second metal reinforcing member away from the silica gel pipe abuts against the insulating barrier part, and the insulating barrier part is located between the second metal reinforcing member and the flange.

[0011] By adopting the technical scheme, the second metal reinforcing member is added and the corresponding groove is provided, so that the second metal reinforcing member can be embedded in the outer wall of the silica gel pipe, further improving the overall strength of the silica gel pipe. At the same time, the insulating barrier part provided on the insulating sheet effectively isolates the direct contact between the second metal reinforcing member and the flange, ensures the absolute insulation effect of the silica gel pipe set during use, avoids current conduction to the flange through the second metal reinforcing member, and eliminates potential electrical safety hazards. In addition, the design of the insulating barrier part also enhances the connection stability between the insulating sheet and the silica gel pipe, prevents the insulating sheet from loosening or mispositioning during long-term use, and ensures the reliability and durability of the silica gel pipe set.

[0012] Preferably, the insulating sheet is fixedly connected with the silica gel pipe.

[0013] By adopting the above technical scheme, the insulating sheet is fixedly connected with the silica gel tube, which can avoid the insulating sheet from deviating or falling off during production, transportation, installation and use, thereby improving the structural stability of the absolute insulating silica gel tube set and improving the use safety.

[0014] Preferably, the thickness of the insulating sheet is 0.01-2mm.

[0015] By adopting the above technical scheme, the thickness of the insulating sheet is 0.01-2mm, which can better block the current and at the same time does not affect the connection stability of the flange and the silica gel tube. This design not only improves the insulation effect of the silica gel tube set, but also ensures the safety and reliability in actual application.

[0016] Preferably, the insulating sheet is a silica gel insulating sheet.

[0017] By adopting the above technical scheme, the silica gel insulating sheet has softness, elasticity and excellent mechanical properties, and also has good insulation characteristics. This makes the silica gel insulating sheet effectively isolate the current in the silica gel tube set, avoid the flange directly contacting the first metal reinforcing layer or the second metal reinforcing piece, thereby ensuring the absolute insulation effect of the silica gel tube set in actual application. In addition, the durability of the silica gel material also improves the service life and reliability of the entire set.

[0018] Preferably, the first metal reinforcing layer and the second metal reinforcing piece are both steel wires spirally wound along the length direction of the silica gel tube.

[0019] By adopting the above technical scheme, the first metal reinforcing layer and the second metal reinforcing piece are both steel wires spirally wound along the length direction of the silica gel tube, which not only significantly improves the overall strength and pressure resistance of the silica gel tube, but also ensures its good flexibility and bending performance. At the same time, due to the continuous winding structure of the steel wire, it can provide uniform support force when the silica gel tube is subjected to external pressure, avoiding damage caused by local stress concentration. In addition, this design also helps to improve the fatigue resistance of the silica gel tube and prolong its service life. Combined with the insulating sheet and the insulating barrier part extended by the insulating sheet, the direct contact between the flange and the second metal reinforcing piece can be effectively isolated, achieving better absolute insulation effect and ensuring safety and reliability in harsh application environment.

[0020] Preferably, the second metal reinforcing piece includes at least one steel wire ring, and each steel wire ring is embedded in a groove on the silica gel tube.

[0021] By adopting the technical scheme, the second metal reinforcing member includes at least one steel wire ring, and each steel wire ring is embedded in the groove on the silica gel tube. Not only the mechanical strength of the silica gel tube is further improved, but also the damage of the silica gel tube caused by external impact is effectively prevented, and the stability and safety of the silica gel tube in a high-pressure environment are ensured. Meanwhile, since each steel wire ring is embedded in the groove on the silica gel tube, the combination between the second metal reinforcing member and the silica gel tube is more firm, the loosening or falling off in a long-time use process is avoided, and the overall reliability of the silica gel tube is improved. In addition, in cooperation with the insulation blocking part of the insulating sheet, the complete isolation between the flange and the second metal reinforcing member is effectively realized, the absolute insulation effect of the silica gel tube set is ensured, the risk that the current is conducted to the flange through the second metal reinforcing member is avoided, and the safety performance of the product is improved.

[0022] In summary, the present application has at least one of the following beneficial technical effects:

DETAILED DESCRIPTION

[0029] The above will be described in detail with reference to the accompanying drawings. Figures 1-2The technical solutions in the embodiments of this invention are clearly and completely described. The described embodiments are only possible technical implementations of this invention and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of this invention without creative effort, and these embodiments are also within the protection scope of this invention. The inventors of this application have discovered that after the silicone tube is processed, the end faces of its two ends will expose steel wires, causing the flanges to come into direct contact with these exposed steel wires, posing a potential hazard. To this end, this application mainly adopts the following absolutely insulating silicone tube kit, including a silicone tube and two flanges installed at both ends of the silicone tube. The silicone tube is provided with at least one first metal reinforcing layer, and insulating sheets are respectively provided at both ends of the silicone tube. The insulating sheets are located between the silicone tube and the flanges, and the first metal reinforcing layer does not contact the flanges, thereby effectively preventing direct contact between the first metal reinforcing layer and the flanges and achieving the purpose of absolute insulation. The following is a further detailed description of this application.

[0030] Example 1

[0031] This application provides an absolutely insulating silicone tube kit. See [link to relevant documentation] Figure 1 The device includes a silicone tube 1 and two flanges 2 installed at both ends of the silicone tube 1. The silicone tube 1 is provided with at least one first metal reinforcing layer 11. The first metal reinforcing layer 11 can be provided on the outer surface of the silicone tube 1 or inside the silicone tube 1. In this embodiment, it is preferably provided inside the silicone tube 1.

[0032] Specifically, the silicone tube 1 is provided with a first silicone tube layer 1, a second silicone tube layer 1, a first metal reinforcing layer 11, a third silicone tube layer 1, and a fourth silicone tube layer 1 sequentially from the outer surface to the inner surface. This gives the entire silicone tube 1 a good layered structure, while further improving the mechanical properties of the silicone tube 1 and further enhancing its pressure resistance and explosion-proof functions.

[0033] Insulating sheets 3 are respectively provided at both ends of the silicone tube 1. The insulating sheets 3 are located between the silicone tube 1 and the flange 2, and the first metal reinforcing layer 11 does not contact the flange 2, effectively preventing direct contact between the first metal reinforcing layer 11 and the flange 2, achieving an absolute insulation effect. Furthermore, the side of the insulating sheet 3 away from the flange 2 is connected to the cross-sections of the first silicone tube 1 layer, the second silicone tube 1 layer, the first metal reinforcing layer 11, the third silicone tube 1 layer, and the fourth silicone tube 1 layer. This enhances the connection stability between the insulating sheet 3 and the silicone tube 1, and effectively prevents the insulating sheet 3 from loosening or misaligning during long-term use, ensuring the durable and reliable insulation effect of the silicone tube 1 assembly.

[0034] Furthermore, the first and fourth silicone tube layers can be made of wear-resistant, high-strength, and insulating silicone materials. The second and third silicone tube layers can be made of silicone resin with good wear resistance, insulation properties, and adhesion to metal materials. This ensures stable adhesion of the first metal reinforcing layer 11 to the silicone tube 1, improves the structural stability of the silicone tube 1, and further enhances the durability of the silicone tube 1 kit.

[0035] The first metal reinforcing layer 11 can be a steel wire spirally wound along the length of the silicone tube 1, or a steel wire coil evenly distributed along the length of the silicone tube 1. In this embodiment, a spirally wound steel wire is preferred.

[0036] The thickness of the insulating sheet 3 can be 0.01mm, 0.1mm, 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, or 2mm. In this embodiment, 0.5mm is preferred. This thickness facilitates installation on the flange 2 onto the silicone tube 1, while also effectively preventing direct contact between the first metal reinforcing layer 11 and the flange 2. Furthermore, the silicone insulating sheet 3 provides excellent insulation, ensuring absolute insulation of the resulting absolutely insulated silicone tube 1 assembly. Specifically, for low-voltage applications, an insulating sheet 3 with a thickness of 0.1mm can be selected; however, for high-voltage applications, it is recommended that the first metal reinforcing layer 11 not contact the flange 2, and an insulating sheet 3 with a thickness of 2mm is used to ensure higher insulation performance. This achieves the desired silicone insulation effect.

[0037] Furthermore, the insulating sheet 3 is fixed to the silicone tube 1 or in contact with the silicone tube 1. In this embodiment, it is preferably fixed to the silicone tube 1. The insulating sheet 3 is a silicone insulating sheet made of silicone resin, which not only has a better insulation effect, but also has better adhesion stability and physical properties. It can avoid the possibility of the silicone insulating sheet 3 being damaged or falling off after long-term use of the silicone tube 1 kit, thus improving its durability.

[0038] The specific implementation principle of Example 1: Through the manufacturing process of silicone tube 1, a fourth silicone tube layer 1 and a third silicone tube layer 1 are formed sequentially. Then, steel wire is wound circumferentially along the length of the surface of the third silicone tube layer 1 to form a first metal reinforcing layer 11. Then, a second silicone tube layer 1 and a first silicone tube layer 1 are formed sequentially to obtain silicone tube 1. The silicone tube 1 is then cut to the appropriate length. Silicone resin liquid is then applied to both ends of the silicone tube 1. After curing, a stable insulating sheet 3 is formed on the silicone tube 1. Flanges 2 are then installed at both ends of the silicone tube 1. At this time, the insulating sheet 3 is located between the first metal reinforcing layer 11 and the flange 2, thereby preventing the flange 2 from directly contacting the first metal reinforcing layer 11, ensuring that the silicone tube 1 assembly achieves absolute insulation, thus improving its durability and practicality.

[0039] Example 2

[0040] The difference between Example 2 and Example 1 is as follows: See Figure 2 It also includes a second metal reinforcement 4. The outer wall of the silicone tube 1 is recessed in the circumferential direction for the second metal reinforcement 4 to be embedded. The groove is located in the first silicone tube 1 layer. The insulating sheet 3 extends along the length of the outer wall of the silicone tube 1 and is provided with an insulating barrier 31. The side of the second metal reinforcement 4 away from the silicone tube 1 is fixedly connected to the insulating barrier 31. The insulating barrier 31 is located between the second metal reinforcement 4 and the flange 2 and prevents the second metal reinforcement 4 from directly contacting the flange 2.

[0041] Furthermore, it can be a steel wire spirally wound along the length of the silicone tube 1, or a steel wire loop evenly distributed along the length of the silicone tube 1. In this embodiment, a spirally wound steel wire is preferred.

[0042] The specific implementation principle of Example 2: The production process of silicone tube 1 forms a first silicone tube layer 1, a second silicone tube layer 1, a first metal reinforcing layer 11, a third silicone tube layer 1, and a fourth silicone tube layer 1. The first silicone tube layer 1 has a recessed groove for spiral winding of steel wire. Then, silicone resin liquid is applied and cured. After curing, the insulating sheet 3 and the insulating isolation part are formed, which can prevent the flange 2 from directly contacting the first metal reinforcing layer 11 and the second metal reinforcing part 4, so as to achieve absolute insulation of the silicone tube 1 kit and further improve its practicality and durability.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
