Abstract

The utility model discloses an attach fitting for plastic tubing and steel pipe, including steel pipe (1), plastic tubing (2), adapter sleeve (3) and seal ring (4), steel pipe (1) is gone up from a left side and is equipped with bushing screw thread (5), seal groove (6) and plastic tubing connecting thread (7) in proper order toward having, and plastic tubing (2) tip is equipped with outstanding edge (8), and adapter sleeve (3) are passed through bushing screw thread (5) on steel pipe (1) and are connected with steel pipe (1) and fix, cup joint on seal groove (6) sealing washer (4), adapter sleeve (3) through the outstanding edge (8) on plastic tubing (2) with plastic tubing (2) grasping and make outstanding edge (8) press the sealing packing ring (4), the technical scheme of the utility model be applicable to the transition of being connected of steel pipe pipeline and plastic conduit, joint sealing performance can be good, and it is convenient to connect, connects difficult production the in position and leak.

Description

Jointing for plastic tube and steel pipe
Technical field
This utility model is related to the jointing of a kind of joint, more particularly, to plastic tube and steel pipe.
Background technology
In prior art, the connection with pipe fitting for the tubing often all can use transit joint, its operational approach is by one The pipe fitting of measured length inserts two coupling pipe elements inwalls and then adopts lock ring by joint area banding, and this mode is in two pipe fittings material The cogging problem of tubing and pipe fitting is can solve when identical, but, when meeting the two pipe fittings material needing joint and being different Its connection sealing just goes down significantly it is impossible to reach good connection effect.
Then, in order to solve such pipe fitting connectivity problem, Chinese utility model patent description 201010535511.5 is public Open the snap joint of such a plastic tube and fastener for connection, plastic tube has one can be connected with the snap joint of fastener for connection The steel tube head of steel pipe, then a cast steel pipe clamp on steel tube head with end of plastic tube outer ring card, is provided with cast steel pipe clamp Sealing ring and sealing sharp thread, corresponding such joint, due to still being sealed in the way of the extruding of outside pipe clamp, thus exist and let out The probability of dew is very big and impracticable, and installation process is also more complicated, needs additional bolts to fix.
Utility model content
(1) technical problem to be solved
The purpose of this utility model is to overcome above-mentioned deficiency present in prior art, and provides one kind to be used for plastic tube With the jointing of steel pipe, its sealing is high, easy to connect.
(2) technical scheme
For solving above-mentioned technical problem, the technical solution of the utility model is: a kind of connection for plastic tube and steel pipe Joint, including steel pipe, plastic tube, connection sleeve pipe and seal washer, from left toward being sequentially provided with telescopic joint screw thread, close on steel pipe Sealing groove and plastic tube connection screw thread, plastics tube end is provided with projecting edge, and described sealing ring is socketed on seal groove, connection sleeve pipe Fixed with fastener for connection by the telescopic joint screw thread on steel pipe, connection sleeve pipe passes through projecting edge on plastic tube by plastic tube Clasp and make projecting edge compression seal washer, by projecting edge on plastic tube, plastic tube is clasped so that plastic tube and steel Pipe without departing from, simultaneously work as compress seal washer effect, realize sealing effectiveness.
Wherein, telescopic joint screw thread is pipe screw thread, and the length of its screw thread is 15mm, because the better tightness of pipe screw thread, Can not be too short for pipe screw thread length.
Wherein, seal groove depth is 1.5mm, the size of corresponding seal washer.
Wherein, projecting edge height is 3mm it is ensured that phenomenon of rupture will not occur during snapping.
Wherein, plastics connection screw thread length is 15mm.
(3) beneficial effect
Compared with prior art, the technical solution of the utility model has the advantage that and is applied to steel pipeline and plastics The connection transition of pipeline, joint sealing performance is good, and easy to connect, connecting portion is not likely to produce leakage.
Brief description
Fig. 1 is overall structure diagram of the present utility model;
In figure description of reference numerals: 1. steel pipe, 2. plastic tube, 3. connection sleeve pipe, 4. seal washer, 5. telescopic joint spiral shell Stricture of vagina, 6. seal groove, 7. plastic tube connection screw thread, 8. projecting edge.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is used for this utility model is described, but is not limited to scope of the present utility model.
Overall structure of the present utility model as shown in figure 1, a kind of jointing for plastic tube and steel pipe, including steel pipe 1st, plastic tube 2, connection sleeve pipe 3 and seal washer 4, from left toward being sequentially provided with telescopic joint screw thread 5, seal groove 6 and on steel pipe 1 Plastic tube connection screw thread 7, described sealing ring 4 is socketed on seal groove 6, and plastic tube 2 end is provided with projecting edge 8, connection sleeve pipe 3 Fixed with fastener for connection by the telescopic joint screw thread 5 on steel pipe 1, the projecting edge 8 that connection sleeve pipe 3 is passed through on plastic tube 2 will Plastic tube 2 clasps and makes projecting edge compress seal washer 4.
Wherein steel pipe 1 and plastic tube 2 passed through the plastic tube connection screw thread 7 on steel pipe before branch sleeve 3 is fixing and connect Together, seal washer 4 can be put in seal groove 6 it is contemplated that threaded between plastic tube 2 and steel pipe 1 does not ensure that Leakage problem, therefore connection sleeve pipe 3 are the same with the material of steel pipe 1, and telescopic joint screw thread 5 is pipe screw thread, in connection sleeve pipe 3 In fixation procedure, by projecting edge 8 on plastic tube 2 drive plastic tube towards sealing ring direction mobile so that plastic tube 2 and steel pipe 1 without departing from, simultaneously work as compress seal washer 4 effect, realize sealing effectiveness.
Shown in Fig. 1, telescopic joint screw thread 5 is pipe screw thread, and the length of its screw thread is 15mm, and seal groove 6 depth is 1.5mm, projecting edge 8 height is 3mm, and plastic tube connection screw thread 7 length is 15mm.
Certainly, the size shown in Fig. 1 can be designed by different size, and to reach used requirement, such conversion all falls Within protection domain of the present utility model.
