Description
Technical field
The utility model relates to pipe fitting, particularly the direct loose joint pipe fitting of a kind of internal thread and many along separate routes pipe fittings.
Background technique
At present the plastic tube that adopts of on the market water engineering mainly is divided into the PPR(polypropylene random copolymer), the polymer of PVC(vinyl), the PE(polyethylene) and the non-crosslinked line style medium density polyethylene tubing that forms of PE-RT(ethene and octene copolymer modification).
PVC is a kind of polymeric material of vinyl, and its material is a kind of amorphism material.The pvc pipe construction can not connect by hot melt, and jointing generally sticks with glue and connects, and the freeze proof and temperature capacity of pvc pipe is all bad, thus be difficult to as hot-water line, because its intensity can not be applicable to the bearing requirements of water pipe, so cold water pipe also seldom uses.In most of situation, pvc pipe is applicable to wireway and blow-off line.
PE-RT is the non-crosslinked line style medium density polyethylene tubing that ethene and octene copolymer modification form, and also is refractory polyethylene.Be that serviceability temperature is no more than 80 ℃ thermoplastic pipe, the radiator heating that therefore is not suitable for long term high temperature hot water uses; The tubing bearing capacity can be lower under the higher state of temperature; PE-RT extrudes control and is not easy, and machining range is narrow, and quality control is difficult.Can carry out hot melt in the construction and connect, but the PE-RT flange is irregular, stop up easily; Welding temperature is also different, and PPR is 260 ℃, and PE-RT is 230 ℃, adopts the easy excessively weldering of PPR special welding machine on the market to cause leaking.In addition, because the easy oxidation of PE material must be adopted special tool to scrape off the scale on surface, otherwise can not form integral pipe truly before the welding, pipeline leaks easily, therefore the more aobvious trouble of construction.
When existing PPR pipe fitting threeway connects, adopt the PPR threeway, tie point has three places, need to adopt hot melt to connect three times, increased cost of material and construction cost, simultaneously, the hidden danger of leaking also increases greatly, particularly complicated at pipeline, threeway connects in the more situation, and cost of material and difficulty of construction increase greatly.
Existing PPR loose joint joint, an end need adopt hot melting way to be connected with PPR tubing, have increased construction cost.
The model utility content
The technical problems to be solved in the utility model is in order to overcome the prior art connection pipe fitting and many along separate routes pipe fittings need to form through multiple welding, and sealability own is relatively poor, has the defective of disclosure risk, and the direct loose joint pipe fitting of a kind of internal thread and many along separate routes pipe fittings are provided.
The utility model solves above-mentioned technical problem by following technical proposals:
The direct loose joint pipe fitting of a kind of internal thread is characterized in that it comprises: the tubular body of a hollow, and an end of this tubular body is provided with the linkage section of a hollow, and the external diameter of this tubular body is greater than the external diameter of this linkage section; The outer wall that the end face of this linkage section and pipeline to be connected are set on this tubular body is adaptive; This tubular body inside is provided with an internal thread link.Described internal thread link can be provided with the adaptive externally threaded metal pipe element of internal thread or is provided with the parts such as externally threaded pipeline pressure table for connecting the end.
Wherein, the end face that this linkage section is set on this tubular body is saddle type.
Wherein, this internal thread link adopts metallic material, and this tubular body adopts polypropylene random copolymer; This internal thread link is connected with the mode of this tubular body by molding and forming.
Wherein, the outer surface of this tubular body is provided with skid resistant course.
The utility model also provides a kind of many along separate routes pipe fittings, and its characteristics are that it comprises the direct loose joint pipe fitting of at least one described internal thread; Should also comprise at least one pipeline by many along separate routes pipe fittings, the tube wall of this pipeline is provided with some connecting through holes adaptive with diameter this linkage section; After this linkage section inserts this connecting through hole, the end face of this linkage section and the outer wall of this pipeline are set on this tubular body are close to; The direct loose joint pipe fitting of described internal thread and described pipeline are sweat soldering, and the end face that this linkage section is set on the described tubular body is face of weld.
In the utility model, but above-mentioned optimum condition combination in any on the basis that meets related domain general knowledge namely gets each preferred embodiment of the utility model.
Positive progressive effect of the present utility model is: the direct loose joint pipe fitting of internal thread of the present utility model and many pipe fittings are integrated with internal thread link and tubular body along separate routes, and be convenient to pipe fitting and be connected connection with accessory.In addition, utilize the outer wall of annular boss and pipeline to fit tightly this design, increased the hot melt area, so that fixing more solid and reliable, avoided the many several forthright hidden danger of leaking of soldering point, reduced difficulty of construction so that install convenient.Realize simultaneously the integrated of pipeline, improved its withstand voltage properties, guaranteed quality of product, especially for the pipeline of multi-path, greatly reduced welding times, improved manufacturing efficiency.

Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, the direct loose joint pipe fitting of the internal thread in the present embodiment comprises the tubular body 1 of a hollow, and the upper-end surface 11 of this tubular body 1 is provided with the linkage section 2 of a hollow, the face of weld when this upper-end surface 11 is welding.The external diameter of the upper-end surface 11 of this tubular body 1 is greater than the external diameter of this linkage section 2.In order to cooperate the outer wall of most pipelines, this upper-end surface 11 is saddle type in the present embodiment.Be provided with the internal thread link 3 that a metallic material is made in the inside of tubular body 1.This internal thread link 3 is connected for the mode of molding and forming with this tubular body 1.Outer surface at tubular body 1 is provided with a skid resistant course 12.
Shown in Fig. 2 and 3, condensate correcting-distribuing device comprises pipeline 100, offers through hole 101 at pipeline 100, and the aperture of this through hole 101 and linkage section 2(see Fig. 1) external diameter adaptive, and less than the external diameter of upper-end surface 11.1 of above-mentioned pipeline 100 and tubular body all adopt PPR tubing to make.At the part of internal thread link 3 pressure gauge 200 that is provided with outer silk that is threaded.Certainly, those skilled in the art also can adopt PVC, PE or PE-RT material to be substituted.The outer wall of this pipeline 100 is traditional circular arc, and it is just adaptive with the outer wall of pipeline 100 to be heterocoelous upper-end surface 11 on the direct loose joint pipe fitting of internal thread.Because the external diameter of upper-end surface 11 is greater than the diameter of through hole 101, increased the hot melt area when pipeline 100 is connected with the direct loose joint pipe fitting of internal thread, when hot melt connects, the outer wall tight connecting of heterocoelous upper-end surface 11 and pipeline 100, face of weld is more firm, and water-proof performance is better.This designs simplification the structure of existing condensate correcting-distribuing device, shortened the installation steps of condensate correcting-distribuing device, solved the many several forthright hidden danger of leaking of soldering point, improved manufacturing efficiency.
