Abstract
Disclosed is a pipe joint used in aluminum composite pipe, which comprises an aluminum composite pipe, a connecting pipe and a nut matched with the thread of the connecting pipe. The two connecting end faces of the connecting pipe are in conical surface; an orifice of the aluminum composite pipe contacted with the connecting pipe is in a horn shape. The above mentioned structure is adopted by the utility model, when in use, as the inner layer surface of wall of the aluminum composite pipe is made of the non metal material, the inner layer surface is contacted closely with orifice of the connecting pipe under the pressure of the nut, not only the sealing effect is good, but also the sealing ring is not needed so that the raw material is saved.
Description
The utility model relates to a kind of pipe fitting connecting head, relates to a kind of pipe joint that is used for aluminium composite pipe specifically.
The existing pipe joint that is used for pipe fitting mainly contains two kinds of structures, the external diameter sealing--and Sealing is enclosed within on the pipe, seals by nut extrusion-deformation.Because Sealing uses the meeting natural aging for a long time, follows the string, and causes seepage, needs periodic replacement, and bigger owing to the temperature difference at cold area, the reason of expanding with heat and contract with cold can be quickened the aging of seal ring, and effect is also undesirable.The internal diameter sealing--owing to take the internal diameter sealing, latus rectum is diminished, reduced the flow of actual caliber from design principle, (about 50%) has caused the waste of tubing virtually, has increased water resistance, and Sealing adopts rubber seal, occur deterioration phenomenon equally, easily cause seepage.
The purpose of this utility model provides a kind of pipe joint that is used for aluminium composite pipe with regard to being at above-mentioned existing in prior technology deficiency.
The purpose of this utility model can realize by following technical measures:
The utility model comprises aluminium composite pipe, connecting tube and with the nut of described connecting tube screw-thread fit, two of described connecting tube connects end faces and is set to the conical surface, the contacted mouth of pipe of described aluminium composite pipe and connecting tube is horn-like.
Advantage of the present utility model just is that connecting end face by two of described connecting tube is set to the conical surface, be arranged to the described aluminium composite pipe and the contacted mouth of pipe of connecting tube horn-like, because the internal layer surface of aluminium composite pipe tube wall is nonmetallic material, under the effect of described nut pressure, touch during connection with described connecting tube mouth of pipe end face close proximity, not only play the effect of good seal, simultaneously also save seal ring, saved raw material, prolonged working life.
The drawing of accompanying drawing is described as follows:
Fig. 1 cuts open figure for master of the present utility model.
The utility model describes in further detail below in conjunction with specific embodiment (accompanying drawing):
As shown in the figure, the utility model comprises aluminium composite pipe 1, connecting tube 2 and with the nut 3 of described connecting tube 2 screw-thread fit, two of described connecting tube 2 connects end faces and is set to the conical surface 4, described aluminium composite pipe 1 is horn-like with the connecting tube 2 contacted mouths of pipe 5.
Claims (1)
1, a kind of pipe joint that is used for aluminium composite pipe, it comprises aluminium composite pipe (1), connecting tube (2), with with the nut (3) of described connecting tube (2) screw-thread fit, it is characterized in that: two of described connecting tube (2) connects end face and is set to the conical surface (4), and described aluminium composite pipe (1) is horn-like with the contacted mouth of pipe of connecting tube (2) (5).
