[0026] To better understand the purpose, structure, and function of this utility model, the following detailed description of an explosion-proof rubber tube, in conjunction with the accompanying drawings, is provided.
[0027] like Figure 1-4 As shown, this utility model discloses an explosion-proof rubber tube, comprising a rubber tube 1, an outer tube sleeved on the outside of the rubber tube 1, a pressure relief pipe 4 on one side of the rubber tube 1, a solenoid valve 5 on the pressure relief pipe 4, and multiple pressure relief holes 6 evenly and orderly distributed at the end of the pressure relief pipe 4. The outer tube includes an upper protective tube 2 and a lower protective tube 3. Multiple equally spaced lower fixing ears 16 are provided on both sides of the lower protective tube 3 along its length direction. Upper fixing ears 17 are provided on both sides of the upper protective tube 2 along its length direction, corresponding one-to-one with the lower fixing ears 16. The lower fixing ears 16 and the upper fixing ears 17 are fixedly connected by screws, washers, and nuts. By setting the upper fixing ears 17 and the lower fixing ears 16, the upper protective tube 2 and the lower protective tube 3 can be fixed together to form a complete circular tube, thereby wrapping around the outside of the rubber tube 1 and providing good protection for the rubber tube 1. Furthermore, by setting the outer tube as a detachable upper protective tube 2 and lower protective tube 3, the installation and disassembly of the overall structure are facilitated, improving practicality. Sealing grooves 14 are provided on both sides of the upper surface of the lower protective tube 3 along its length. Sealing edges 18 corresponding to the sealing grooves 14 are provided on both sides of the bottom of the upper protective tube 2, and the size of the sealing edges 18 matches the size of the sealing grooves 14. Arc-shaped openings 15 corresponding to the pressure relief pipes 4 are provided on one side of both the upper protective tube 2 and the lower protective tube 3. Through the cooperation between the sealing edges 18 and the sealing grooves 14, the sealing performance is better when the upper protective tube 2 and the lower protective tube 3 are connected. The upper protective tube 2 is composed of a glass fiber layer 19, a fireproof silicone layer 20 and a connecting pure rubber sleeve 21 from the inside to the outside. The structure of the lower protective tube 3 is the same as that of the upper protective tube 2. Through the cooperation between the glass fiber layer 19, the fireproof silicone layer 20 and the connecting pure rubber sleeve 21, the upper protective tube 2 and the lower protective tube 3 can withstand the burning of (1090±80)℃ for 15 minutes, with good fire resistance and improved safety.
[0028] Multiple equally spaced flexible hoses 13 are provided on the inner walls of the upper protective tube 2 and the lower protective tube 3 along their length. The flexible hoses 13 are in contact with the outer wall of the rubber tube 1. The flexible hoses 13 have an arc-shaped structure and are made of a shrinkable material. By setting the flexible hoses 13, after the upper protective tube 2 and the lower protective tube 3 wrap around the rubber tube 1, the flexible hoses 13 can contact the outer wall of the rubber tube 1. When the internal pressure of the rubber tube 1 increases and expands, it will exert pressure on the flexible hoses 13, thereby squeezing the flexible hoses 13 to deform, thus preventing the rubber tube 1 from directly bursting the outer tube.
[0029] Multiple pressure sensors 12 are arranged in an orderly manner on the inner walls of both the upper protective tube 2 and the lower protective tube 3, and a controller 7 is installed on one side of the upper surface of the upper protective tube 2. The controller 7 is electrically connected to the pressure sensors 12 and the solenoid valve 5, and is equipped with a display screen 8, a button 9, an indicator light 10, and an alarm horn 11. When the internal pressure of the rubber tube 1 increases, it expands, thereby squeezing the pressure sensor 12. The pressure sensor 12 is a device or apparatus that can convert pressure signals into usable output electrical signals according to a certain rule. The pressure sensor 12 is usually composed of a pressure-sensitive element and a signal processing unit. According to different test pressure types, the pressure sensor 12 can be divided into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors. The pressure sensor 12 is one of the most commonly used sensors in industrial practice. It is widely used in various industrial automation environments, involving many industries such as water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military industry, petrochemicals, oil wells, power, ships, machine tools, and pipelines. When the pressure value detected by the pressure sensor 12 reaches the preset value, the controller 7 will control the solenoid valve 5 to open, so that the air pressure in the rubber tube 1 can be discharged through the pressure relief hole 6. When the pressure value detected by the pressure sensor 12 is less than the preset value, the controller 7 will control the solenoid valve 5 to close. When the pressure value detected by the pressure sensor 12 is higher than the preset maximum value, the indicator light 10 will flash red, and the alarm horn 11 will sound an alarm to alert the surrounding personnel, which is safe. At the same time, the display screen 8 can display the current pressure value in real time.
[0030] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
