Above-mentioned crude metal pipe and thin metal pipe are aluminium matter pipe.
Above-mentioned aluminium matter pipe, having at least place, a connecting port to be provided with by self tube wall pier in two connecting port presses the outer rim that forms to protrude in the ring part of tube wall, the open sides of ring part is the annular flat end face, with its joint that directly connects or with being provided with and its suitable planar end surface that docks with transition holding element between the corresponding joints that it directly connects at it.
Above-mentioned aluminium matter pipe, two place, connecting port is equipped with by self tube wall pier and presses the outer rim that forms to protrude in the ring part of tube wall.
Above-mentioned ring part, its ring body section become opening semicircle arcuation or U word shape inwardly.
Above-mentioned joint locking fitting, comprise be nested with the connecting port inside tube on one's body locking nut and be arranged on thread section on the corresponding joints, cooperate with thread section by locking nut and realize docking of connecting port and corresponding joints.
The ring part double as at place, above-mentioned connecting port is the spacing stop part of locking nut.
The inner sealing surface of above-mentioned locking nut is the planar base surface suitable with the ring part connecting part.
The utility model beneficial effect is: the usual copper pipe that uses of crude metal pipe or thin metal pipe in the prior art is replaced with aluminium matter pipe, can reduce greatly and produce and maintenance cost.Aluminium matter pipe is taked subordinate's technical approach: be provided with by self tube wall pier at the place, connecting port and press the outer rim that forms to protrude in the ring part of tube wall, the open sides of ring part is the annular flat end face, with its joint that directly connects or with being provided with and its suitable planar end surface that docks with transition holding element between the corresponding joints that it directly connects at it, the annular flat end face of aluminium matter pipe joins with the planar end surface that docks of joint etc. during connection, and cooperate precession to tighten up with the thread section of its corresponding joints by joint locking fitting such as locking nut, force two planar end surfaces closely to contact and realize being tightly connected, this kind technical approach, distortion when ring part can be guaranteed its stressed sealing is no more than scope, can not cause harmful deformation to aluminium matter pipe ring shape planar end surface, can repeatedly repeat to connect and use, satisfy seal request; Overcome the problem that can't avoid directly taking prior art in the production practices process, to run into effectively: promptly because aluminium matter pipe is softer, it is connected use once with corresponding joints after, directly formed bell mouth shape in corresponding port by expansion, no longer be suitable for repeating for the second time to connect, disassemble a posterior restoration aluminium matter pipe and just may scrap and abandon, cause waste or the like.
