Abstract
The utility model belongs to the field of pipeline joints, in particular to a butt joint which is used in plastic pipelines. The butt joint comprises a pair of plastic pipes. The butt joint is characterized in that two flange plates are respectively sleeved on pipe orifices of two plastic pipes which need connecting, two convex edges which form a whole with butt joint orifices of the two plastic pipes are respectively arranged on the butt joint orifices of the two plastic pipes, packing rings are sleeved on the outer edge of the convex edge outside the butt joint orifices of the plastic pipes after butt joint, and a fastening piece is threaded through a through hole on the flange plates and is connected and fastened together with the flange plates. Since the butt joint adopts the flange plates to butt the plastic pipes, thereby the butt joint orifices are more durable, the butt joint also uses a double pointed nail and a nut to fasten the flange plates, which enables the butt joint and disassembly of the pipelines to be more convenient, the butt joint is butted with the outdoor movable pipes furthermore, pipe clamps are installed outside the packing rings on the butt joint orifices, the sealing is more compact, the sealing effect is further intensified, simultaneously, the butt joint orifices of the plastic pipes are also fastened, the durable pressure on the butt joint orifices is also improved, and thereby fluid can not be leaked easily.
Description
Technical field
The utility model belongs to the pipe coupling field, particularly a kind of butt joint that is used for plastic pipe.
Background technique
Plastic tube generally is to be raw material with the plastic resin, adds oiling agent, stabilizer etc., forms through extrusion process in tube producer with the method that plastifies.Since it have light weight, corrosion-resistant, aesthetic in appearance, do not have characteristics such as bad smell, easy processing, easy construction, its application area also more and more widely, not only can be used for water supply and drainage, combustion gas conveying, can also be used as electrical casing pipe (electric wire, cable).In the middle of the concrete application of plastic tube, especially in large-scale outdoor construction, often two tubes need be docking together.At present, the docking mode as plastic tube mainly contains the butt joint of iron pipe clamp, iron wire binding butt joint, gluing butt joint.Accompanying drawing 1 is the cross-sectional view of iron pipe clamp butt joint, inserts and the suitable iron pipe 2 of its diameter plastic tube 1 in, utilizes pipe clamp 3 fastening at two splicing positions of plastic tube 1 and iron pipe 2, uses bolt 4 snapping pipe clamps 3 afterwards again.Iron wire binding butt joint then is simply to utilize iron wire to bundle the plastic tube of fastening butt joint.2 in accompanying drawing is two plastic tubes 1 to be enclosed within the plastic tube sleeve pipe 5 that adapts with its diameter directly dock, again at plastic tube docking port place adhesive sealing.The plastic tube docking port that these modes are docked comes off easily, butt joint place not compression resistance, leak fluid, butt joint trouble, time-consuming take a lot of work, keep in repair frequent.
The model utility content
For overcoming the deficiency of the butt joint of plastic pipe in the above-mentioned prior art, the purpose of this utility model be exactly be to provide a kind of docking port firmly, compression resistance, the easy butt joint that is used for plastic pipe of dismounting.
For achieving the above object, the technological scheme that the utility model is taked is as follows: the utility model mainly comprises a pair of plastic tube, the innovation part of this model utility is: two plastic tube mouth of pipe places that need to connect respectively are with a flange plate, two plastic tube docking port places have a convex limit that becomes one with it respectively, be with seal ring on the convex limit outer rim of the outside, docking port place of the plastic tube after the butt joint, fastening piece passes the through hole on the flange plate and two flange plates is connected, tightens together.
Consider that from the angle of being convenient to moulding the section selection on described convex limit be a circle, the effect on convex limit is to block the flange plate of both sides, makes it slippage not take place and breaks away from plastic tube.
Described convex limit exceeds through hole shaft axis that the outer peripheral vertical height of plastic tube is greater than 1/3 flange plate to the outer peripheral vertical height of plastic tube, but less than the through hole shaft axis of flange plate to the outer peripheral vertical height of plastic tube.
For bearing bigger load in the docking port place that makes plastic tube, described fastening piece is preferably stud bolt and is mated the nut of use, and such bolt and nut makes dismounting more easy.
Described seal ring is preferably rubber ring.
Plastic tube docking port place is the weak spot of not withstand voltage, the easy leak fluid of plastic tube often, for strengthening the sealing effect at this place, fastening plastic tube joint, the outside of described seal ring can also be equipped with pipe clamp, between pipe clamp by bolt snapping, fastening.
The utility model is owing to adopt flange plate butt joint plastic tube, so the docking port place is more withstand voltage, again with stud bolt and be mated the nut clamp flange sheet of use, makes that pipeline butt joint dismounting is more easy, the butt joint of more closing the outdoor activities pipeline; The outside of the utility model docking port place seal ring is equipped with pipe clamp, seals closelyr, has further strengthened sealing effect, and simultaneously also fastening plastic tube docking port has improved the pressure of docking port place tolerance, thereby has been difficult for leak fluid.

Embodiment
As shown in Figure 3, a kind of butt joint that is used for plastic pipe, mainly comprise a pair of plastic tube 1, two plastic tubes, 1 mouth of pipe place that needs to connect respectively is with a flange plate 6, two plastic tube 1 docking port places have a convex limit 7 that becomes one with it respectively, be with seal ring 8 on convex limit 7 outer rims of the outside, docking port place of the plastic tube after the butt joint 1, fastening piece 9 passes the through hole on the flange plate 6 and two flange plates 6 is connected, tightens together.
During operation, at first respectively each with flange plate 6 concentric locking collars on two plastic tubes 1 that needs connect, burning plastic tube 1 mouth of pipe afterwards is squeezed into and exceeds plastic tube 1 outer peripheral section and be circular convex limit 7, guarantee that its through hole shaft axis that highly is greater than 1/3 flange plate 6 is to plastic tube 1 outer peripheral vertical height, but less than the through hole shaft axis of flange plate 6 to plastic tube 1 outer peripheral vertical height, so that block the flange plate 6 of both sides, do not break away from plastic tube 1.Treat after the cooling of plastic tube 1 mouth of pipe, at 7 places, convex limit butt joint plastic tube 1.Convex limit 6 outer rims in the outside, docking port place of plastic tube 1 put seal ring 8 sealings, seal ring preferred rubber circle then.Be to strengthen sealing effect, the docking port of fastening plastic tube 1, the outside of rubber ring can also be equipped with pipe clamp 3, and 3 of pipe clamps are by bolt 4 snappings, fastening.At last, for bearing bigger load in the docking port place that makes plastic tube 1, fastening piece 9 preferred stud bolts and be mated the nut of use, be fastenedly connected the flange plate 6 at plastic tube 1 two ends, the big load that such bolt and nut can not only bear, and make that the dismounting of plastic tube 1 is more easy, be fit to moving at any time of pipeline.
