Technical field
The present invention relates to a kind of pipe joint device, especially for the various large, medium and small joint of aluminium-plastic composite pipe and PEX, plastic tube.
Background technique
In the prior art, the applicant once was designed for the joint of aluminium-plastic composite pipe and plastic tube, and had applied for Chinese invention patent, and the patent No. is to be CN1128305C ZL00116071.0, notice of authorization number, it is that " a kind of pipe joint is used for the connection of aluminium-plastic composite pipe or plastic tube.It comprises: the pipe joint body, crimp rings, the high elasticity seal ring that have engaging body; Have five layers of annular groove on the engaging body surface, be with the high elasticity seal ring that protrudes in the annular groove edge slightly on the annular groove; Being provided with circular window near front end on the pressure welding case is used to inspect body and whether is installed to safe position location.Pipe joint combines the back with body chimeric firm.Owing to adopted the high elasticity seal ring, so the influence that its function can not expanded with heat and contract with cold by material.Its tensile strength is big simultaneously, volume is little, construction is simple and easy, meets the demand of building the boundary." this joint sealing performance is good, bond strength is big, is accepted by American-European engineering circle and generally uses, but because of the problem of construction technique, but can't promote all the time at home, and main cause is that joint can't combine fixing when constructing with instrument.
Summary of the invention
The objective of the invention is: a kind of pipe joint device is provided, this device with have firm chimeric effect after body combines, the influence that not expanded with heat and contract with cold by material, and fix crimping sleeve by the PE fixed cover, convenient construction, joint is combined with body, and tension is strong and volume is little, meets building circle demand.
Technological scheme of the present invention is: a kind of pipe joint device, comprise adapter body, engaging body, crimping sleeve, engaging body is provided with several annular grooves, be provided with the high elasticity seal ring in the annular groove, the bottom of described engaging body is provided with engagement groove, be fixed with the PE fixed cover on the engagement groove, the endoporus of PE fixed cover is step-like, the aperture at rear portion and engagement groove close-fitting are fixed, and anterior macropore voltage supply connects sleeve pipe and inserts, and the macropore forward position is provided with a circle flange, outer, crimping sleeve rear end is provided with a circle groove, in the time of in the macropore of crimping sleeve insertion PE fixed cover, flange embeds in the groove, and PE fixed cover and crimping sleeve are fixed.
The further technological scheme of the present invention is: a kind of pipe joint device, comprise adapter body, engaging body, crimping sleeve, engaging body is provided with several annular grooves, be provided with the high elasticity seal ring in the annular groove, the bottom of described engaging body is provided with engagement groove, be fixed with the PE fixed cover on the engagement groove, the endoporus of PE fixed cover is step-like, the aperture at rear portion and engagement groove close-fitting are fixed, and anterior macropore voltage supply connects sleeve pipe and inserts, and the macropore forward position is provided with a circle flange, outer, crimping sleeve rear end is provided with a circle groove, in the time of in the macropore of crimping sleeve insertion PE fixed cover, flange embeds in the groove, and PE fixed cover and crimping sleeve are fixed; The rear portion of described PE lining is provided with window.
Advantage of the present invention is:
1. the present invention has increased a PE fixed cover, the PE fixed cover is fixed on the engagement groove of engaging body bottom, and the inner ring at the PE fixed cover is provided with the overhanging flange of a circle, be used to embed the groove of insertion outer, crimping sleeve rear portion wherein, crimping sleeve disengaging configuration in the time of can avoiding constructing guarantees that crimping sleeve, body, the effective crimping of engaging body fix.
2. PE fixed cover of the present invention rear portion is provided with window, can inspect body and whether be inserted into home, prevents that body from getting loose before crimping is not finished, and does not reach in the safe crimping critical field.
Description of drawings
The invention will be further described below in conjunction with embodiment:
Fig. 1 is for being decomposing schematic representation of the present invention;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is a sectional view of the present invention.
Wherein: 10 adapter body; 20 engaging bodies; 21 engagement grooves; 22 annular grooves; The 30PE fixed cover; 31 apertures; 32 macropores; 33 flanges; 34 windows; 40 crimping sleeves; 41 grooves; 50 high elasticity seal rings; 60 bodys.
Embodiment
Embodiment: as Fig. 1, Fig. 2, shown in Figure 3, a kind of pipe joint device, comprise adapter body 10, engaging body 20, PE fixed cover 30, crimping sleeve 40, high elasticity seal ring 50, adapter body 10 is can be according to user's requirement, and is made into size miscellaneous and form is selected for the user.
The bottom of engaging body 20 is provided with engagement groove 21, be fixed with PE fixed cover 30 on the engagement groove 21, the endoporus of PE fixed cover 30 is step-like, the aperture 31 and engagement groove 21 close-fittings at rear portion are fixed, anterior macropore 32 voltage supply connect sleeve pipe 40 and insert, macropore 32 forward positions are provided with a circle flange 33, outer, crimping sleeve 40 rear end is provided with a circle groove 41, in the time of in the macropore 32 of crimping sleeve 40 slotting PE fixed covers 30, flange 33 embeds in the groove 41, make PE fixed cover 30 fixing with crimping sleeve 40, the rear portion of PE lining 30 is provided with window 34.
PE fixed cover 30 can prevent that the aluminium-plastic composite pipe mouth of pipe aluminium strip from contacting with the joint copper material, produces so-called potential corrosion.PE fixed cover 30 design can be blocked the engagement groove 21 of engaging body 20 bottoms, so that fixing crimping sleeve 40, causes crimping sleeve 40 displacements when being unlikely construction, and causes crimping incorrect.30 designs of PE fixed cover can be blocked in the crimping tool groove tool displacement when avoiding crimping.PE fixed cover 30 rear portions are provided with window 34, and whether body 60 puts in place in the time of can inspecting coupling compression joint, prevent that body 60 from getting loose before crimping is not finished, and do not reach the crimping critical field.
Crimping sleeve 40 is to utilize vacuum annealing to arrive the copper tube of certain intensity, and the equalization of pressure that body 60 is born at each position of ring-type can prevent the seepage that the very fast expansion contraction that colds and heat succeed each other produces.
The present invention can make bilateral, threeway or many various joints such as logical as required.
The present invention has improved the various shortcomings of aluminum current plastic composite or PEX, plastic joint, and have advantage, and the good watertight advantage of cold-resistant heat, expansion, contraction is arranged, tensile strength is big, volume is little, construction is simple and easy, then this body diameter is close with caliber, and cheap.
