[0002] In a pipeline system, the sealing performance of the pipeline port is directly related to the operating efficiency and safety of the entire system. In order to seal the pipeline port, it is of great practical significance to develop a pipeline port sealing structure.

[0003] The reference announcement number is CN213271586U, which is a pipeline port connection sealing structure. The connection sealing structure includes a sealing tube placed at the connection position of two pipeline ports and a fixing part installed inside the two ends of the sealing tube for expanding the sealing tube and tightly contacting the inner wall of the pipeline; the fixing part includes a clamp installed inside one end of the sealing tube, the clamp is annular with an opening, and the opening position of the clamp has a connecting piece that contacts the two ends of the clamp for expanding the clamp. The connection sealing structure can effectively seal the pipeline port connection. It has a simple structure and high sealing performance. Under the extrusion force of the clamp, the sealing tube is effectively tightly connected to the inner wall of the pipeline to achieve the purpose of sealing. It is stable to install and easy to use. As can be seen from the above, although the sealing structure can be well applied, the pipeline port is usually sealed by a clamp sealing method, which makes the sealing structure inconvenient to operate and use, and often bothers users. Utility Model Content

[0004] The purpose of the present invention is to provide a pipeline port sealing structure to solve the problem that although the sealing structure proposed in the above background technology can be well applied, the pipeline port is usually sealed by a clamp sealing method, which makes the sealing structure somewhat inconvenient when operating and using.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pipeline port sealing structure, comprising a pipeline body, an end cover is arranged above the pipeline body, the bottom end of the end cover touches the top end of the pipeline body, a circular seat body is arranged at the center position inside the end cover, both ends of the circular seat body extend to the outside of the end cover, a threaded interface is provided on the inner wall of the upper end of the pipeline body, a threaded joint is installed on the internal thread of the threaded interface, the top end of the threaded joint extends to the outside of the threaded interface and is fixedly connected to the bottom end of the end cover, and an annular cavity is provided on the outer wall of the lower end of the end cover.

[0006] Preferably, the diameter of the pipe body is equal to the diameter of the end cover, and the diameter of the threaded joint is equal to the inner diameter of the threaded interface, so that the threaded joint can be screwed into the interior of the threaded interface.

[0007] Preferably, an outer sealing ring is provided inside the annular cavity, and the bottom end of the outer sealing ring touches the top end of the pipe body. The outer sealing ring is provided so that the port of the pipe body can be sealed from the outside.

[0008] Preferably, a screw joint is provided at the center of the top end of the circular seat body, and the lower end of the screw joint is provided with a cylindrical structure, so that the external thread can be placed and processed through the provision of the screw joint.

[0009] Preferably, an external thread is provided on the outer wall of the screw joint, and the external thread is provided so that the end cover can be screwed with the help of an internal thread cylindrical tool.

[0010] Preferably, an inner sealing ring is installed on the inner wall of the pipe body below the threaded interface, and the top of the inner sealing ring touches the bottom end of the threaded joint. Through the setting of the inner sealing ring, the port of the pipe body can be sealed from the inside.

[0011] Compared with the prior art, the beneficial effects of the present invention are: the pipeline port sealing structure not only makes the installation and connection of the end cover more convenient, thereby improving the convenience of the use of the sealing structure, but also can use an internal threaded cylindrical tool to rotate and disassemble the end cover, thereby further improving the convenience of the use of the sealing structure, and ensuring the sealing effect of the sealing structure on the pipeline body port when in use;

[0012] By rotating the end cap and screwing the threaded joint into the inside of the threaded interface, the end cap can be threadedly installed on the top of the pipe body, so that the end cap can block and seal the port of the pipe body. Compared with the traditional clamp connection method, this sealing structure is more convenient to connect, thereby improving the convenience of using the sealing structure;

[0013] By providing a screw joint at the top of the circular seat and providing an external thread on the outer wall of the screw joint, the end cap can be rotated and disassembled by the tool by simply screwing a cylindrical screwing tool provided with an internal thread into the outer wall of the screw joint, thereby further improving the convenience of using the sealing structure;

[0014] By setting the outer sealing ring, the connection position between the pipe body and the end cover is sealed from the outside, and by setting the inner sealing ring, the connection position between the threaded joint and the threaded interface is sealed from the inside, thereby being able to perform a dual sealing operation on the port of the pipe body, thereby ensuring the sealing effect of the pipe body port when the sealing structure is in use.
