Abstract
The utility model provides a three-way connecting pipe and belongs to the pipe fittings technical field. The three-way connecting pipe comprises a straight pipe and a branch pipe which are made of plastics. The branch pipe is connected on the side part of the straight pipe and communicated with the straight pipe. The three-way connecting pipe is characterized in that a tubular insert made of metal is fixed in a pipe opening of the branch pipe. The straight pipe and the branch pipe are connected as a whole and made of plastics, thereby resulting in low cost and good corrosion resistance; and the metal tubular insert fixed in the branch pipe can enhance the strength of the three-way connecting pipe.
Description
Technical field
The utility model belongs to the pipe fitting technical field, relates to a kind of adapter, particularly a kind of t-joint.
Background technique
Along with the extensive use of plastic pipe, its used connection pipe fitting seems particularly important, and in known technology, existing tee pipe fitting mainly is wrought iron threeway, plastic three-way, stainless steel tee pipe fitting.Also provide a kind of compound tee pipe fitting just like Chinese patent publication number CN2503297Y, it moulds the combined type tee pipe fitting by connecting the iron that plastic inner lining forms in the wrought iron threeway overcoat, its intensity height, strong, the novel structure of rotproofness, being suitable for the pipe part connect various plastic pipes fittings and rubber and plastic, metal, is a kind of novel tee pipe fitting.
But, above-mentioned wrought iron threeway, stainless steel threeway, compound tee pipe fitting cost height, easily corroded by acidic materials, though and the plastic three-way pipe fitting has overcome above two shortcomings, its intensity is not high, in use tends to take place fracture phenomena.
Summary of the invention
The purpose of this utility model is to have above-mentioned problem at existing tee pipe fitting, and the t-joint that a kind of cost is low, rotproofness is strong, intensity is high is provided.
The purpose of this utility model can realize by following technical proposal: a kind of t-joint, comprise straight tube and arm by plastic production, this arm is connected the sidepiece of straight tube and communicates with straight tube, it is characterized in that, the mouth of pipe internal fixation of described arm has the tubular inserts of being made by metal, and the inwall of described tubular inserts is provided with screw thread.
Arm and the straight tube composition t-joint that communicates, this inserts adopts the intensity that metal is made can increase inserts.This inserts adopts the structure of tubular to match with arm, and like this, this tubular inserts can strengthen the intensity of whole arm.
In above-mentioned a kind of t-joint, described tubular inserts with surface that straight tube contacts on be provided with anti-edge.Like this, the tubular inserts can be fixed on the arm, and can not rotate between the arm.
In above-mentioned a kind of t-joint, described tubular inserts is being provided with circular step one near on the inwall of straight tube end.This step can prop up the pipeline that is connected with arm, and above-mentioned pipeline is not put in the straight tube.
In above-mentioned a kind of t-joint, described tubular inserts is provided with screw thread at step to the inwall of arm opening part.Arm is connected with pipeline by screw thread, for the installation and removal of t-joint are carried conveniently.
In above-mentioned a kind of t-joint, also be provided with some wire stiffening ribs on the described t-joint outer surface, this stiffening rib is parallel with arm with straight tube respectively.Stiffening rib is mainly used to strong arm and straight tube.
In above-mentioned a kind of t-joint, described straight tube and arm are connected as a single entity.
In above-mentioned a kind of t-joint, described straight tube becomes the T font with arm.
In above-mentioned a kind of t-joint, be equipped with circular step two in the port of described straight tube two ends.This step can prop up the pipeline that is connected with straight tube.
Compared with prior art, straight tube of this t-joint and arm are connected as a single entity and adopt plastic production, and cost is low, and antiseptic property is good; Arm internal fixation at this t-joint has the tubular inserts of being made by metal simultaneously, and this inserts plays the effect of strengthening arm, and therefore, this t-joint also has advantages of high strength.
Description of drawings
Fig. 1 is the perspective view of this t-joint.
Fig. 2 is the plan structure schematic representation of this t-joint.
Among the figure, 1, straight tube; 2, arm; 3, inserts; 4, anti-edge; 5, step one; 6, screw thread; 7, stiffening rib; 8, step two.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this t-joint comprises straight tube 1 and arm 2, and this arm 2 is connected the sidepiece of straight tube 1 and communicates with straight tube 1, and arm 2 is connected as a single entity with straight tube 1 and becomes T font, the mouth of pipe internal fixation of described arm 2 that the tubular inserts of being made by metal 3 is arranged.This t-joint adopts a moulded section, also is provided with some wire stiffening ribs 7 on the t-joint outer surface of being told, and this stiffening rib 7 is parallel with arm 2 with straight tube 1 respectively.
This t-joint is mainly used in the water delivery field, because the tee pipe fitting that wrought iron and stainless steel are made is easily oxidized and corrosion, therefore, this t-joint adopts plastic production.This t-joint branched pipe 2 and straight tube 1, and the pipeline that is connected with arm 2 can produce torsion to arm 2, arm 2 tends to break.So this t-joint is provided with the tubular inserts of being made by metal 3 in arm 2, like this, this tubular inserts 3 can increase the intensity of arm 2.And the stiffening rib 7 on the above-mentioned t-joint outer surface is mainly used to reinforce arm 2 and straight tube 1, and the intensity of whole t-joint is strengthened.
As depicted in figs. 1 and 2, the tubular inserts 3 of this t-joint with surface that straight tube 1 contacts on be provided with instead along 4, tubular inserts 3 is being provided with circular step 1 near on the inwall of straight tube 1 end, and described tubular inserts 3 also is provided with screw thread 6 at step to the inwall of arm 2 opening parts.Described instead can making between tubular inserts 3 and the arm 2 along 4 can not rotate.Above-mentioned circular step 1 can prop up the pipeline that is connected with arm 2, can fixing tube and it is not put in the straight tube 1.Described arm 2 is connected with pipeline by screw thread 6, for the installation and removal of t-joint are provided convenience.
Be equipped with circular step 28 in the straight tube 1 two ends port, this step 28 can prop up the pipeline that is connected with straight tube 1.This straight tube 1 adopts the form of socket to be connected with pipeline.
