DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The principles and features of the present utility model will be described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.
[0018] See Figures 1 to 2 , a high-temperature and high-pressure jacketed magnetic flap level gauge, comprising a main cavity 8. A heat tracing interface 1 is provided on the side of the main cavity 8 for the inlet and outlet of the heat tracing medium. An end cover 10 is installed at the top of the main cavity 8, and an exhaust valve 11 is provided above the end cover 10 for discharging the gas inside the main cavity 8. A bottom welding flange 2 and a bottom mating flange 3 are successively installed at the bottom of the main cavity 8, and the bottom welding flange 2 and the bottom mating flange 3 are fixedly connected by bolts and nuts. A drain valve 12 is further provided below the bottom mating flange 3;
[0019] A floating ball 7 is provided inside the main cavity 8. A thrust spring 9 is installed at the bottom of the floating ball 7. The floating ball 7 is a high-temperature and high-pressure resistant floating ball, and its floating ball magnet uses a special high-temperature resistant magnet, which can be used in a high-temperature environment for a long time without magnetic force reduction. The magnet is designed with a 360° ring magnet, with stable and strong magnetic force, effectively preventing the magnetic flap from leaking and flipping. The magnetic force line is consistent with the immersion line, with high measurement accuracy. The floating ball is integrally sealed by TIG precision argon arc or laser welding, and a pressure support ring design is made inside. Each section of the outer shell of the straight pipe section of the floating ball is designed with a groove ring to increase the stress area of the floating ball. Therefore, the floating ball of this product has excellent high-pressure resistance performance.
[0020] An external heat tracing jacket 5 is provided outside the main cavity 8. The heat tracing jacket 5 wraps around the outside of the main cavity 8. There is a flowing high-temperature medium in the heat tracing jacket 5. By installing a 360° fully wrapped heat tracing jacket 5 outside the main cavity 8 and transferring heat through the flowing high-temperature medium in the jacket, the core lies in designing the structure of the jacket and selecting suitable materials to ensure effective heat transfer and safe operation.
[0021] The overall design uses a double-layer eccentric heat tracing jacket. The structure of the jacket is configured according to the shape and size of the inner cavity to ensure that the jacket can completely cover the surface of the inner cavity that needs to be heated and the heat can be evenly transferred.
[0022] The jacket is made of materials that are resistant to high temperatures and corrosion to ensure long-term stable operation in high-temperature and corrosive environments.
[0023] Optimize the design structure of the jacket. Determine the thickness and size of the jacket according to the temperature, pressure, and flow rate of the high-temperature medium to ensure safe operation and efficient heating, maximize the heat transfer efficiency, and thus reduce energy consumption and heating time.
[0024] The heat tracing medium inside the jacket is completely suitable for steam / water / oil. Different materials of jackets are configured according to different media.
[0025] The jacket can be configured with different numbers and types of interfaces according to the working conditions. Typical installation interfaces are in the form of capillary tubes, threads, flanges, or welding.
[0026] It is possible to select the flow from top to bottom or from bottom to top according to the type of high-temperature medium and the heat tracing requirements.
[0027] An indicator panel and components 4 are also provided outside the heat tracing jacket 5. The indicator panel on the indicator panel and components 4 is made of 304 / 316 stainless steel material, with high-temperature and corrosion resistance. The glass tube in the U-shaped groove of the indicator on the indicator panel and components 4 adopts a vacuum extraction process to prevent the interference of water vapor and dust on the liquid level observation.
[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
