Description
Technical field
The utility model relates to the air-conditioning pipe joint, especially relates to a kind of person in charge's import and branched pipe import and is parallel to each other, and its coupling part is an intersecting body, and main, branched pipe all is provided with the air-conditioning auxiliary tube joint of enlarging pull and stretch district with welding welded part convenient for assembly.
Background technology
In the pipe joint processing of air-conditioning, reason owing to numerous factors such as volume, positions, designing requirement compactness, assembling or the convenient welding of cooling duct, the more important thing is to have leakage phenomenon to take place, in general, pipe joint is processed with modes such as casting, die casting, its wall thickness is thicker, and subsequent technique can not lack, as car, polishing, screw thread processing, chamfering or the like, but the joint of using in the air-conditioning, require wall thickness thinner mostly, weight reduction is easy to heat radiation, the part joint requires turnover mouth of pipe direction opposite, becomes 180 degree.Few products is produced can be two canal curvature backlash holes and straight tube welding, and quality not only there is not assurance like this, and efficient is low, and cost is very high again.Joint form in the air-conditioner is various, has plenty of by its functional requirement design designs such as its locus needs of the main consideration that has and difficulty of processing, cost.
As the patent No. is 90106377.0 T-branch used in pipe-lines and moulding process thereof, mainly is that three-way pipe is made by superplastic alloy, and moulding process does not generally need secondary operations by superplastic gas-bulging and the moulding of extruding composite force.Invent the hot extruded seamless threeway manufacture method that a kind of complexes are provided as the patent No. for 85108775, under the effect of forcing press, seamless steel tube blank is carried out hot extrusion, form arm and trunk line quadrature, and finish the manufacture method of equal tee.A kind of air-conditioner difference three-way pipe that provides for 200620084362.4 utility models as the patent No., characteristics be the axis of two interfaces of threeway body on same axis, the span of the 3rd the interface axis of threeway body and the included angle A of two other interface axis is 20 °＜A＜70 °.
And for example the patent No. is the tee pipe fitting that 200420083057.4 1 kinds of PAPs or plastic tube are used, and a kind of being connected with the tubing that secretly buries installation of exposing is provided, and connects simple and directly, needs with the space less.As the patent No. is that 94227622.1 utility models are a kind of no screw thread tee pipe couplings, and main feature is the upper and lower cover that tee pipe coupling is divided into dimidiation, connects with bolting.Also having the patent No. is that 200520147320.6 utility models are a kind of copper three-way pipes, comprise a person in charge, be hollow copper pipe, its stage casing tool one hollow branch holder, one arm is hollow copper pipe, and external diameter is not more than the internal diameter of branch holder, and after being sleeved on branch holder, the copper alloy wlding seam that is higher than 900 ℃ with unleaded and fusing point forms.
Summary of the invention
The purpose of this utility model is in the tee pipe coupling that solves air-conditioning, the inlet pipe mouth becomes 180 degree angles with two outlet spouts, the problem that production efficiency is low, provide a kind of inlet pipe and arm to adopt intersecting body to be connected, can disposal molding, and inlet pipe all is provided with the enlarging district with the convenient air-conditioning auxiliary tube joint that welds with arm.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: this air-conditioning auxiliary tube joint, comprise straight tube, arm, arm is provided with two, straight tube and two arms link into an integrated entity by intersecting body, the center line of straight tube and two arms is parallel to each other, and be in the same plane, the diameter of straight tube is greater than the diameter of arm, one end of straight tube is provided with the enlarging district, whole pipe joint pass through part mutually can disposable drawing and forming, avoid adopting welding procedure to make difference three-way pipe weld because of the not firm hidden danger that ftractures of solder joint.
As preferably, one end of described two arms is provided with flared section, the purpose of three-way connection provides the preferable approach of air-conditioning auxiliary tube global formation, one end of arm adopts enlarging, the branched pipe of shapes of any curves is welded on the pipe joint, weld is the pipe straightway, if this end of arm is not established flared section, also can add enlarging to branched pipe one end that will receive on the pipe joint, assembly welding can obtain the air-conditioning auxiliary tube product that internal diameter equates equally like this, the internal diameter of flared section equates with soldered tube outer diameter, inserts in the flared section when soldered pipe like this, and the internal diameter of arm just coincides with soldered ips.
As preferably, the junction of described intersecting body and straight tube and two arms, for passing through camber line mutually, because the diameter of straight tube is bigger than the diameter of arm, in fact one end of intersecting body is exactly the diameter dimension of straight tube, stretching with a kind of transition camber line makes the cambered surface of intersecting body and arm connecting portion smooth naturally, and the resistance of ducting is less.
As preferably, described straight tube, arm, intersecting body are that copper material is made, can certainly be with the good alloy material of plasticity.
Therefore, the utility model is that a kind of reasonable in design, cost of manufacture are low, and the inlet pipe mouth becomes 180 degree angles with two outlet spouts, and the resistance of ducting is less, and offers a kind of air-conditioning auxiliary tube joint that needs to weld the preferred weld district of pipe on it.
