Limitation.
Below with reference to Fig. 1-Fig. 7 description according to the pipeline jointing construction of the utility model embodiment.
Pipeline jointing construction according to the present utility model includes connecting line 120 and connects pipe clamp 130, wherein connecting line
120 have abutting end, and abutting end is used to be set in tubing 110 to be connected, and Z-shaped opening is provided on abutting end, Z-shaped to open
Mouth includes: along the first notch 101 of connecting line 120 axially arranged and the second notch 102, and one end of the first notch 101 is spacious
The first wall surface 101a is opened and has, the second notch 102 has the second wall surface 102a close to the first notch 101, in banding
When abutting end, the first wall surface 101a and the second wall surface 102a are bonded each other.Outer peripheral surface of first notch 101 in abutting end
On, and the first notch 101 is it is so structured that rectangular aperture, and the first wall surface 101a is the wall surface of the first notch, and setting is the
The inside of one notch, the second notch 102 is similarly disposed at abutting end, and the second notch 102 and the first notch 101 are in abutting end
Radially successively arrange, and the second notch 102 is likewise constructed to rectangle, and there are four wall surfaces for the second notch 102 tool, wherein leaning on
The wall surface of nearly first notch, 101 side, which is that the second wall surface 102a, the second wall surface 102a is adjacent with the first wall surface 101a, to be set
It sets, and the first wall surface 101a and the second wall surface 102a be in abutting end stress, that is, when banding abutting end, the first bottom
Wall surface 101a is gradually overlapped with the second wall surface 102a, to reduce the diameter of abutting end, tightens abutting end, improves piping connection
The airtightness of structure.
First wall surface 101a and the second wall surface 102a can be suitable on same straight line in connecting line 120
When tightening, the width of the first notch 101 and the width of the second notch 102 is enabled gradually to narrow, and the first wall surface 101a and bottom
Wall surface is gradually overlapped, and guarantees that the bore of connecting line 120 is variable.
Pipeline jointing construction further includes connection pipe clamp 130, and connection pipe clamp 130 is suitable for clamping engagement end so that the first wall surface
101a and the second wall surface 102a are bonded each other, and connection pipe clamp 130 exerts a force to the circumferential direction of abutting end, to enable the first wall surface 101a
It is gradually bonded with the second wall surface 102a, and narrows the first notch 101 and the width of the second notch 102 gradually, so that cooperation
The diameter at end shortens, by abutting end with connect tubing banding and seal.
Connect pipe clamp 130 not by wait connect tubing 110 and connecting line 120 clamp when, tubing 110 to be connected
Outer diameter no more than abutting end in connecting line 120 internal diameter, to ensure that tubing 110 to be connected can the easily company of extending into
It takes in road 120, after the tubing 110 wait connect extend into the abutting end of connecting line 120, is pressed from both sides by connecting pipe clamp 130
Tightly, during connecting the clamping of pipe clamp 130, the first wall surface 101a and the second wall surface 102a are bonded each other, make first to lack
The width of mouth 101 and the width of the second notch 102 reduce, and reduce the caliber of abutting end in connecting line 120, make the interior of abutting end
Surface is fitted closely with the outer surface of tubing 110 to be connect, and to seal tubing 110 and connecting line 120 to be connected, is prevented
There is a phenomenon where gas leakage between tubing 110 and connecting line 120 to be connected.
When the tubing 110 wait connect is thermally deformed, since the outside of abutting end is arranged in connection pipe clamp 130, so as to
The tubing 110 of connection can not expand outward radially, and then enable tubing 110 to be connected along axial (the i.e. length side of pipeline
To) expansion, to drive abutting end to be pulled up in the axis of pipeline, since the first wall surface 101a and the second face bottom wall 102a are equal
