Description

Technical Field

[0001] This application relates to the field of heating jackets, and more particularly to a heating jacket for use between a valve body and a bypass pipe. Background Technology

[0002] Pipelines are devices used to transport gases or liquids and are widely used in various industrial fields. To prevent the gas in the valve body and bypass pipeline from crystallizing at low temperatures and sticking to the pipeline, causing blockage and hindering normal transport, heating jackets are usually installed.

[0003] Traditional heating jackets use Velcro to secure both ends. However, Velcro has a drawback: it is easily affected by external dust or impurities, causing dirt and grime to accumulate inside. This prevents the rounded and rough sides from fully engaging when pressed, resulting in a weak adhesion and making the heating jacket prone to detaching at the Velcro connection. This affects the installation stability of the heating jacket in actual use. Utility Model Content

[0004] To address the aforementioned issues, this application provides a heating jacket for use between a valve body and a bypass pipe.

[0005] The heating jacket for the valve body and bypass pipe provided in this application adopts the following technical solution:

[0006] A heating jacket for use between a valve body and a bypass pipe includes a heating jacket body, a connecting assembly on the heating jacket body, the connecting assembly including a plurality of elastic bands fixedly connected to one end of the heating jacket body, a hook fixedly connected to the end of the elastic bands away from the heating jacket body, and a plurality of connecting rings fixedly connected to the side wall of the heating jacket body away from the elastic bands by means of a cloth strip, the hooks being hooked to the connecting rings respectively.

[0007] By adopting the above technical solution, when using the device, the user first places the heating jacket body on the valve body and the bypass pipe, then pulls the elastic band to make the heating jacket body tightly wrap the valve body and the bypass pipe. After that, the hooks are hooked to the connecting rings through the elastic bands to connect the two ends of the heating jacket body to prevent it from unfolding. This process avoids the heating jacket from easily coming loose when the Velcro has low adhesion, which would affect the installation stability of the heating jacket in actual use.

[0008] Preferably, a heating wire is installed inside the heating jacket body, and an electric wire is provided on one side of the heating jacket body. One end of the electric wire passes through the heating jacket body and is electrically connected to the heating wire, and a plug is fixedly connected to the end of the electric wire away from the heating wire.

[0009] By adopting the above technical solution, the heating wire can be powered by connecting the plug to an external power source, thereby heating the heating jacket body and the valve body and bypass pipe, preventing the gas from crystallizing at low temperature and sticking to the pipe, causing blockage.

[0010] Preferably, a temperature controller is installed on the wire, and the temperature controller is electrically connected to the heating wire.

[0011] By adopting the above technical solution, the temperature of the heating wire can be controlled by the temperature controller, and the heating power of the heating wire can be automatically adjusted to maintain a constant temperature.

[0012] Preferably, a baffle for closing the hook is hinged to the side wall of the hook near the elastic band. A spring is fixedly connected to the side wall of the baffle. The end of the spring away from the baffle is fixedly connected to the side wall of the hook. The end of the baffle away from the hook abuts against the side wall of the hook away from the elastic band.

[0013] By adopting the above technical solution, pressing the baffle causes the spring to contract, disengaging one end of the baffle from one end of the hook, allowing the hook to engage with the connecting ring. Then, releasing the baffle allows the spring to rebound, causing one end of the baffle to abut against one end of the hook, thus sealing the opening of the hook and preventing the hook from detaching from the connecting ring.

[0014] Preferably, the heating jacket body includes a surface layer, an inner layer, and a flame-retardant layer, and the heating wire is located within the flame-retardant layer.

[0015] By adopting the above technical solution, the flame-retardant layer can improve the non-combustibility of the heating jacket body, preventing malfunctions when the heating wire is heating and preventing the heating jacket body from burning due to excessively high temperature.

[0016] Preferably, an alarm light is installed on the heating jacket body, and the alarm light is electrically connected to the temperature controller.

[0017] By adopting the above technical solution, when the heating wire malfunctions and cannot control the temperature, and when the temperature exceeds or falls below the temperature set by the temperature controller, the temperature controller can control the alarm light to flash and sound an alarm, making it easier for personnel to detect the fault in a timely manner.

[0018] Preferably, a stop block is fixedly connected to the side wall of the hook away from the elastic band, and the stop block is in contact with one end of the baffle.

[0019] By adopting the above technical solution, the stop block can prevent the connecting ring from being squeezed into the contact area between the baffle and the hook, causing the spring to contract and the connecting ring to detach from the hook.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application utilizes the combination of elastic bands, hooks, and connecting rings to design a system where, during use, the user first places the heating jacket body on the valve body and bypass pipe. Then, by pulling the elastic band, the heating jacket body tightly wraps around the valve body and bypass pipe. Afterward, the hooks are connected to the connecting rings via the elastic bands to connect both ends of the heating jacket body, preventing it from unfolding and allowing for proper installation. This design minimizes the risk of the heating jacket loosening due to low Velcro adhesion, which could affect the installation stability of the heating jacket in actual use.

[0022] 2. By connecting the plug to an external power source, the heating wire can be powered, which in turn heats the heating jacket body and the valve body and bypass pipe, preventing low-temperature gas crystallization that could stick to the pipe and cause blockage. Attached Figure Description

[0028] The following is combined with Figure 1-Figure 4 This application will be described in further detail.

[0029] This application discloses a heating jacket for use between a valve body and a bypass pipe.

[0030] Reference Figure 1 , Figure 2 and Figure 4A heating jacket for use between a valve body and a bypass pipe includes a heating jacket body 1, a through hole for the valve body to pass through on the heating jacket body 1, and a connecting assembly on the heating jacket body 1, the connecting assembly including an elastic band 2, a hook 3 and a connecting ring 4.

[0031] Multiple elastic bands 2 are provided and fixedly connected to one end of the heating jacket body 1. Multiple hooks 3 are provided and fixedly connected to the end of the elastic band 2 away from the heating jacket body 1. Multiple connecting rings 4 are provided and fixedly connected to the side wall of the heating jacket body 1 away from the elastic band 2 by a cloth strip. The hooks 3 are respectively hooked to the connecting rings 4.

[0032] Reference Figure 1 and Figure 3 Heating wire 5 is installed inside the heating jacket body 1. A wire 6 is provided on one side of the heating jacket body 1. One end of the wire 6 passes through the heating jacket body 1 and is electrically connected to the heating wire 5. A plug 7 is fixedly connected to the end of the wire 6 away from the heating wire 5. By connecting the plug 7 to an external power source, power can be supplied to the heating wire 5, so that the heating wire 5 can heat the heating jacket body 1 and heat the valve body and bypass pipe to prevent gas from crystallizing at low temperature and sticking to the pipe to block the pipe.

[0033] Reference Figure 1 and Figure 3 A temperature controller 8 is installed on the wire 6. The temperature controller 8 is electrically connected to the heating wire 5. The heating jacket body 1 is provided with multiple heating jacket bodies 1 that can be connected by connectors, so that the temperature controller 8 can control the temperature of multiple heating jacket bodies 1 at the same time. The temperature controller 8 can control the temperature of the heating wire 5 and automatically adjust the heating power of the heating wire 5 to maintain a constant temperature.

[0034] Reference Figure 4 A baffle 9 for closing the hook 3 is hinged to the side wall near the elastic band 2. A spring 10 is fixedly connected to one side wall of the baffle 9. The end of the spring 10 away from the baffle 9 is fixedly connected to the side wall of the hook 3. The end of the baffle 9 away from the hook 3 abuts against the side wall of the hook 3 away from the elastic band 2. By pressing the baffle 9, the spring 10 is contracted, disengaging one end of the baffle 9 from one end of the hook 3, so that the hook 3 is engaged with the connecting ring 4. Then, the baffle 9 is released, and the spring 10 rebounds, causing one end of the baffle 9 to abut against one end of the hook 3, thus closing the opening of the hook 3 and preventing the hook 3 from disengaging from the connecting ring 4.

[0035] Reference Figure 3The heating jacket body 1 includes a surface layer 11, an inner layer 12, and a flame-retardant layer 13. The heating wire 5 is located inside the flame-retardant layer 13. The surface layer 11 and the inner layer 12 are made of polytetrafluoroethylene coated cloth. The flame-retardant layer 13 is located between the surface layer 11 and the inner layer 12 and is made of glass fiber cotton. It can improve the non-flammability of the heating jacket body 1 and prevent the heating wire 5 from malfunctioning during heating and the heating jacket body 1 from burning due to excessive temperature. The flame-retardant layer 13 can improve the non-flammability of the heating jacket body 1 and prevent the heating wire 5 from malfunctioning during heating and the heating jacket body 1 from burning due to excessive temperature.

[0036] Reference Figure 2 An alarm light 14 is installed on the heating jacket body 1. The alarm light 14 has a horn and is electrically connected to the temperature controller 8. When the heating wire 5 malfunctions and cannot control the temperature, or when the temperature exceeds or falls below the temperature set by the temperature controller 8, the temperature controller 8 can control the alarm light 14 to flash and sound the horn, so that personnel can detect the fault in time.

[0037] Reference Figure 4 A stop 15 is fixedly connected to the side wall of the hook 3 away from the elastic band 2. The stop 15 is in contact with one end of the baffle 9. The stop 15 can prevent the connecting ring 4 from being squeezed into the contact point between the baffle 9 and the hook 3, causing the spring 10 to contract and causing the connecting ring 4 to detach from the hook 3.

[0038] The implementation principle of a heating jacket for a valve body and bypass pipe according to an embodiment of this application is as follows: In use, the user first places the heating jacket body 1 on the valve body and bypass pipe. Then, by pulling the elastic band 2, the heating jacket body 1 tightly wraps the valve body and bypass pipe. Next, the hooks 3 are hooked onto the connecting rings 4 via the elastic band 2, connecting both ends of the heating jacket body 1 to prevent unfolding. The heating jacket body 1 is then installed. The plug 7 is then connected to an external power source to supply power to the heating wire 5. The temperature of the heating wire 5 is controlled by the temperature controller 8, automatically adjusting the heating power of the heating wire 5 to maintain a constant temperature, thus heating the heating jacket body 1 and the valve body and bypass pipe. This prevents low-temperature gas crystallization and adhesion to the pipe, avoiding blockage. It also minimizes the risk of the heating jacket loosening due to low Velcro adhesion, which could affect the installation stability of the heating jacket in actual use.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
