Description

Technical Field

[0001] The utility model relates to the technical field of high-level tank pipe orifices, and particularly relates to a connection assembly for high-level tank pipe orifices which is convenient for maintenance. Background Art

[0002] The high-level tank can also be called an expansion tank. In the liquid-phase heat-conducting oil furnace heating system, the setting of the expansion tank is essential. The high-level tank is mostly used in chemical equipment such as reaction kettles to accommodate important functions such as the thermal expansion of the heat-conducting liquid. As the name implies, the high-level tank is usually installed at the highest position of chemical equipment such as reaction kettles to facilitate high-level operation.

[0003] When the existing pipe orifice connection assemblies are assembled and connected, most of them use corresponding sealing rings to seal the splicing parts. However, during long-term use, a simple sealing ring is difficult to ensure good sealing at the pipe orifice connection. Once leakage occurs at the splicing part, it will affect the normal use of the connection assembly;

[0004] The existing patent (Publication No.: CN220980584U) discloses a connection assembly for high-level tank pipe orifices. After the first connecting pipe and the second connecting pipe are spliced, the user can hold the handwheel and rotate it. Then the rotation of the handwheel drives the screw rod to rotate. As the screw rod rotates, it will drive the push block to slide continuously, gradually pushing and compressing the air in the inner cavity of the connecting end. Then the air will enter the inside of the sealing air cushion through the connecting pipe and the one-way air valve provided on the sealing air cushion, causing the sealing air cushion to gradually expand until the sealing air cushion abuts against the second connecting pipe, playing an additional sealing role between the first connecting pipe and the second connecting pipe. Further, after rotating the handwheel to make the push block return to its original position, the air in the inner cavity where the push block is located will be replenished through the ventilation groove, facilitating the next inflation of the sealing air cushion, so as to improve the sealing performance of the splicing part between the first connecting pipe and the second connecting pipe during actual operation, reduce the occurrence of leakage at the splicing part, and ensure the normal use of the entire connection assembly.

[0005] In view of the above problems, the existing patent gives a solution. The existing high-level tank pipe orifices are relatively prone to leakage because they will experience temperature and pressure changes, as well as material aging. It is required that the joints of the high-level tank pipe orifices are convenient for maintenance and have a certain tightness. If a failure occurs, it is convenient to quickly repair the high-level tank pipe orifices.

[0006] Therefore, a connection assembly for high-level tank pipe orifices which is convenient for maintenance is proposed. Content of the Utility Model
