Abstract
The utility model discloses a connection pipe fitting of high-pressure air passages, which resolves problems that the existing connection pipe fittings of high-pressure air passages are easy to be aged, complex in structure and easy to be damaged and wastes time and labor when mounted and dismounted. The connection pipe fitting comprises a connecting copper pipe (1), a seal head (2) and a seal nut (3), an extruding bell mouth (4) is arranged at the end of the connecting copper pipe (1) and movably arranged in an inner bore of the seal nut (3), a conical boss (5) is arranged at the top end of the seal head (2), the side wall of the seal head (2) is provided with outer thread (7) which is fittingly screwed with inner thread (6) arranged in the inner bore of the seal nut (3), and the conical boss (5) arranged at the top end of the seal head (2) is movably sleeved with the extruding bell mouth (4) arranged at the end of the connecting copper pipe (1). The connection pipe fitting has the advantages of convenient installation and fine sealing performance.
Description
Technical field
The utility model relates to a kind of mechanical connection pipe fitting of high-pressure gas pipeline.
Background technique
The connection pipe fitting of pressurized gas pipeline is the critical component of high pressure air pipeline, and the sealing of connection pipe fitting and reliability are related to the normal operation of high-pressure gas circuit system.The connection pipe fitting of existing pressurized gas pipeline exists aging easily, complex structure, the problem that loading and unloading are wasted time and energy and damaged easily.
Summary of the invention
