Description

Technical Field

[0001] The utility model relates to the technical field of pipeline flanges, in particular to a pipeline flange. Background Art

[0002] Pipe flange is a detachable joint that fixes two pipes, pipe fittings or equipment on a flange respectively, then adds a flange gasket between the two flanges, and finally tightens the two flanges with bolts to make them tightly combined.

[0003] The authorization publication number "CN211624503U" records "a pipe flange, including an upper flange and a lower flange, wherein an upper groove is provided on the right side of the bottom end of the upper flange, and a lower groove is provided on the right side of the bottom end of the lower flange, and the position of the upper groove corresponds to the position of the lower groove. The utility model forms an aquifer by setting the upper groove and the lower groove, and by the position of the upper groove corresponding to the position of the lower groove. When the pressure inside the pipe is too large, the flange connection is the most pressurized place. When liquid seeps out, it is collected by the aquifer to prevent the pressure from directly pressing the liquid out. For a long time, the flange connection will slowly seep water and finally cause the flange connection to rupture, thereby improving the life of the pipe flange. The utility model is more practical and suitable for wide promotion and use."

[0004] The above patent avoids the direct pressure from squeezing out the liquid, which will cause the flange connection to slowly leak water over a long period of time and eventually cause the flange connection to rupture, thereby increasing the life of the pipeline flange. It is relatively practical and suitable for widespread promotion and use. However, when the flange seal fails, the water source can only be turned off to prevent water from flowing out during maintenance. However, the flange is far away from the water source, which delays the use time, causing water to continue to flow out and waste resources. Utility Model Content

Through the use of a sealing mechanism, the outlet of the upper flange can be sealed to ensure that when the sealing ring is replaced during use, the flow can be stopped in a short time to avoid continuous outflow of liquid and waste of resources. Through the use of a push column, the sealing mechanism can be contracted so that the upper flange and the lower flange can be connected, thereby realizing use and ensuring the applicability of use.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a pipeline flange, including:

[0007] An upper flange, wherein a lower flange is provided at the bottom of the upper flange, and two external grooves are equidistantly provided on the outer surfaces of the upper flange and the lower flange;
