Abstract
The utility model belongs to a three-way water pipe connecting joint, which comprises a pipe joint body, a locking nut and a clamping ring, wherein the pipe joint body is provided with a screwed joint and a taper joint or the taper joint only and is injected and formed from engineering plastic. The utility model has the characteristics of advanced and reliable production technology, low production cost and use cost, reliable seal, strong high temperature resistance, strong oil resistance, strong acid and alkaline resistance, noble metal saving, etc. The utility model overcomes the defects of high cost, complex processing, more noble metal consumption, poor sealing reliability, etc. in the background technology that the joint body, the locking nut and the clamping ring are made from copper materials, and a rubber ring is used for sealing. The three-way pipe joint is especially suitable for the connection between aluminum plastic composite pipes or between aluminum plastic composite pipes and galvanizing pipes.
Description
The utility model belongs to a kind of water pipe adapter, particularly a kind of connection aluminium-plastic composite pipe or connection aluminium-plastic composite pipe and used for galvanized tube three-way union.Especially be fit to be used between the aluminium-plastic composite pipe in the civil building water supply and sewage work or aluminium-plastic composite pipe and galvanized pipe between be connected.
At present, the pipe joint that is used to connect aluminium-plastic composite pipe or connects aluminium-plastic composite pipe and used for galvanized tube in water supply and sewage work all adopts copper material to make through machining.Wherein still adopt conventional internal thread to be connected with the galvanized pipe connecting end; Then adopt the grade of band seal groove directly to cooperate with the water pipe internal surface with the aluminium-plastic composite pipe connecting end through tube-shaped joint, promote hold-down ring by locking nut again aluminium-plastic composite pipe is linked into an integrated entity with the tube-shaped joint fit sealing and with joint body, its Sealing employing rubber ring.This type of link reaches the mode that is connected sealing with aluminium-plastic composite pipe, has the big processing complex process of noble metal consumption, produces and the user cost height; Adopt seal with elastometic washer, defectives such as it is high temperature resistant, oil resistant, resistance to acids and bases difference.
The purpose of this utility model is the characteristic at aluminium-plastic composite pipe, and designing a kind of is the three-way union of base material with engineering plastics; This pipe joint can carry out from motive sealing, and need not add seal ring etc. when being fastenedly connected with aluminium-plastic composite pipe.To reach the production technology that simplifies pipe joint, improve its sealing and high temperature resistant, oil resistant, resistance to acids and bases, reduce and produce and user cost, save purposes such as noble metal.
Solution of the present utility model is to be PE class plastics according to the inside and outside wall of aluminium-plastic composite pipe, the characteristics that plasticity is stronger, adopt the engineering plastics close to make the pipe joint base material with its performance, make pipe joint body and locking nut by molding and forming, simplifying production technology, and utilize both plasticity to realize plastic-aluminum pipe and joint selfsealings.In order to improve self-packing reliability, the joint design that cooperates with inboard wall of tube body on the pipe joint is tapered, good to guarantee the fashionable contact with it of body cover; By the nut pushing, when hold-down ring is fastening with it, realize then from motive sealing; This end still adopts conventional screw connection structure when one is connected with galvanized pipe.Therefore, the utility model comprises the three-way union body, hold-down ring and locking nut; Key is that it is that outer ring surface is the taper joint of the conical surface that this three-way union body has two connecting heads at least, and all the other one both can be taper joint, and also can be conventional inipple; Locking nut then is connected with the pipe joint body of taper joint end by screw thread; Hold-down ring is located between locking nut and the joint body, then is placed in tube wall during use.Above-mentioned outer ring surface is the taper joint of the conical surface, and its tapering generally is advisable with 3 °～5 °.
The utility model is owing to adopt engineering plastics to make pipe joint body and locking nut by molding and forming, thereby simplified production technology greatly, reduced cost; And will make realization from motive sealing with plastic-aluminum combined pipe connector, and good airproof performance not only, and high temperature resistant, oil resistant, resistance to acids and bases are also good; Its cost of production only is about 40% of a background technique.Therefore, the utlity model has production technology advanced person, reliable, production and user cost is low, the sealing is reliable and high temperature resistant, oil resistant, resistance to acids and bases are good, save characteristics such as noble metal.
Accompanying drawing and description of drawings
Fig. 1 is the utility model embodiment 1 structure and and body annexation schematic representation.
Among the figure: 1. pipe joint body, 2. taper joint, 3 threaded connector .4. locking nuts, 5. hold-down ring, 6, aluminium-plastic composite pipe.
Embodiment 1
Accompanying drawing 1 is the present embodiment accompanying drawing.Connecting internal diameter with two ends is Φ 14mm, external diameter is the aluminium-plastic composite pipe of Φ 18mm, the other end is an example with the zinc-plated three-way union that is connected in 1/2 o'clock: joint body 1 and two locking nuts 4 all adopt the ABS plastic molding and forming, its middle joint intracavity diameter Φ 10mm, long 75mm; Inipple 3 structures, size are all same with background technique, taper joint 2 long 15mm, and termination external diameter external diameter Φ 13.4mm, tapering is 4 °.Locking nut 4 and joint body 1 are threaded by M25; Hold-down ring 5 present embodiments still adopt the used copper hold-down ring of background technique.All the other and background technique are together.
Embodiment 2
Present embodiment be three ends all with internal diameter Φ 14mm, external diameter is that the three-way union that the aluminium-plastic composite pipe of Φ 18mm connects is an example: change the inipple in the accompanying drawing 13 into taper joint, and set up corresponding locking nut 4 and hold-down ring 5, its structure, size are all same with all the other two taper joints 2.All the other are all same with embodiment 1.
Claims (2)
1, a kind of three-way union comprises the three-way union body, hold-down ring and locking nut; It is characterized in that it is that outer ring surface is the taper joint of the conical surface that this pipe joint body has two connecting heads at least, all the other one both can be taper joint, also can be conventional inipple; Locking nut then is connected with the pipe joint body of taper joint end by screw thread; Hold-down ring is located between locking nut and the joint body, then is placed in tube wall during use.
2, by the described three-way union of claim 1, it is characterized in that described outer ring surface is the taper joint of the conical surface, its tapering generally is advisable with 3 °～5 °.
