Another object of the present utility model is for the problems referred to above, and provide a kind of reasonable in design, structure is simple, the pipe joint structure of the outer composite tube joint of employing that water quality is secure.
For achieving the above object, the utility model have employed following technical proposal: outer composite tube joint of the present utility model, comprise adapter cover and there is the body that at least one accepts the mouth of pipe, one end of described adapter cover is fixed on accepts in the mouth of pipe, the other end is exposed to be accepted outside the mouth of pipe and be provided with outside thread outside this end of adapter cover, described body is made up of nonmetallic material, described adapter cover is made up of metallic material, it is characterized in that, described adapter cover is inner has the annular stop circle extended radially inwardly, in the described undertaking mouth of pipe, there is the ring-shaped step extended radially inwardly, described annular stop circle entirety to be embedded in ring-shaped step and thus form towards the one side accepted outside the mouth of pipe annular sealing surface be made up of nonmetallic material at annular stop circle, described annular sealing surface outer rim stretches out along the axis accepting the mouth of pipe and forms at adapter cover inwall the cylinder be made up of nonmetallic material, described cylinder forms the anti-edge being fastened on adapter cover exterior edge face.During use, this pipe joint causes its structural strength to obtain enhancing because outside have employed the adapter cover that metallic material makes, higher hydraulic pressure can be born, again because of adapter cover be connected with other pipe fitting time, nonmetal ring-shaped step is formed the annular sealing surface leant with other metal pipe elements, avoid making water quality be affected because of the corrosion of metallic material, and owing to adopting thread connecting mode, very convenient during connection outer tube, and it is anti-along protecting the end face of accepting the mouth of pipe from from the infringement of applied external force to it, make the cooperation of adapter cover and the undertaking mouth of pipe tightr simultaneously.
In above-mentioned outer composite tube joint, described body is any one in three-way union, straight tube pipe joint, bend pipe pipe joint, cross pipe.Applied range.
In above-mentioned outer composite tube joint, described body to be positioned at outside socket pipe mouth and to be provided with concaveconvex structure at adapter cover away from one end of opening.Concaveconvex structure is as handgrip part, and during dismounting, can play anti-skidding effect, dismounting is laborsaving.
The pipe joint structure of above-mentioned outer composite tube joint is as described below: the pipe joint structure of this outer composite tube joint, comprise outer composite tube joint and the body with nonmetal internal surface, described body inserts in the described undertaking mouth of pipe, and the end face of described body insertion undertaking mouth of pipe one end and annular sealing surface lean thus make the undertaking mouth of pipe and body connecting part form nonmetal water channel excessively.Make water quality not vulnerable to pollution when pipeline transmits.
Compared with prior art, the advantage of this outer composite tube joint and pipe joint structure thereof is: water quality is vulnerable to pollution not, structural strength is high, the outside nonmetallic material that adopt are cost-saving, joint adopts metal pipe element to improve the intensity of joint, be threaded and non-skid feature owing to taking, be convenient to dismounting.
Accompanying drawing explanation
Fig. 1 provides the sectional drawing of the utility model embodiment.
Fig. 2 provides the utility model example structure schematic diagram.
In figure, body 1, accept the mouth of pipe 11, ring-shaped step 12, annular sealing surface 13, cylinder 14, annular instead along 141, adapter cover 2, annular stop circle 21, outside thread 22, body 3.
Embodiment
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
As shown in Fig. 1 to 2, this outer composite tube joint, comprise adapter cover 2 and there is the body 1 that at least one accepts the mouth of pipe 11, one end of described adapter cover 2 is fixed on accepts in the mouth of pipe 11, the other end is exposed to be accepted outside the mouth of pipe 11 and be provided with outside thread 22 outside this end of adapter cover 2, described body 1 is made up of nonmetallic material, described adapter cover 2 is made up of metallic material, it is characterized in that, described adapter is overlapped 2 the inners and is had the annular stop circle 21 extended radially inwardly, there is in the described undertaking mouth of pipe 11 ring-shaped step 12 extended radially inwardly, described annular stop circle 21 entirety to be embedded in ring-shaped step 12 and thus form towards the one side accepted outside the mouth of pipe 11 annular sealing surface 13 be made up of nonmetallic material at annular stop circle 21, described annular sealing surface 13 outer rim stretches out along the axis accepting the mouth of pipe 11 and forms the cylinder 14 be made up of nonmetallic material at adapter cover 2 inwall, described cylinder 14 is formed and is fastened on the anti-along 141 of adapter cover 2 exterior edge face, during use, this pipe joint causes its structural strength to obtain enhancing because outside have employed the adapter cover 2 that metallic material makes, higher hydraulic pressure can be born, again because of adapter cover 2 be connected with other pipe fitting time, nonmetal ring-shaped step 12 is formed the annular sealing surface 13 leant with other metal pipe elements, avoid making water quality be affected because of the corrosion of metallic material, and owing to adopting thread connecting mode, very convenient during connection outer tube, and instead protect the end face of accepting the mouth of pipe 11 from from the infringement of applied external force to it along 141, make the cooperation of adapter cover 2 and the undertaking mouth of pipe 11 tightr simultaneously.
