Abstract
The utility model relates to a new style pipeline joint which is a pipeline connector. The utility model has the advantages of simple structure, convenient assembly and disassembly, convenient maintenance and good sealing performance outside the connection of pipelines. The pipeline joint is composed of sleeve pipes, a brake screw, a tightening nut, nuts and sealing washers, wherein, the tightening nut is screwed in a screw hole which is arranged on the wall of the sleeve pipe, and the sealing washers are arranged between the sleeve pipe and the sleeve pipe, or the sleeve pipe and an elbow body, or the sleeve pipe and a T-bend body, and are also connected by the nuts.
Description
New-type pipe joint is a kind of pipe joint.
The connection of existing pipeline generally is to be connected with the internal thread of pipe coupling behind the sealing material that twines raw meal belt and so on the outside thread of pipe end, this connecting means, need at the tube end threading, installation and maintenance are cumbersome, and the joint easily produces leakage phenomenon.
The purpose of this utility model is: a kind of design proposal of New-type pipe joint is provided, and it is simple in structure, mounting or dismounting, easy to maintenance, pipeline junction good airproof performance.
The technical solution of the utility model is: New-type pipe joint has sleeve pipe, clamping screw, fastening screw nut, nut, seal washer, clamping screw is screwed in the screw on the casing wall, fastening with fastening screw nut, between sleeve pipe and sleeve pipe or sleeve pipe and curved head body or sleeve pipe and the three-way body seal washer is arranged, and connect with nut.Nut one end inwall has convex shoulder, on the other end inwall internal thread is arranged.Sleeve pipe one end has outside thread or convex shoulder, and 1-5 screw arranged on the other end tube wall.Seal washer is made with the urethane rubber of flexible, oil resistant, acid resistant alkali, heatproof.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1: the straight joint diagrammatic sketch,
Fig. 2: the elbow connection diagrammatic sketch,
Fig. 3: the tee union diagrammatic sketch,
Among the figure: 1, pipeline, 2, pipeline, 3, sleeve pipe, 4, sleeve pipe, 5, clamping screw, 6, clamping screw, 7, nut, 8, seal washer, 9, curved head body, 10, three-way body, 11, nut, 12, fastening screw nut, 13, fastening screw nut, 14, fastening screw nut, 15, clamping screw, 16, nut, 17, sleeve pipe.
Embodiment 1:
The straight joint (see figure 1) has sleeve pipe 3,4, clamping screw 5,6, nut 7, seal washer 8 and fastening screw nut 12,13 constitute, the end that sleeve pipe 3 is connected with nut 7 has outside thread, 1-5 uniform screw arranged on the other end tube wall, on the end outer wall that sleeve pipe 4 is connected with nut 7 boss is arranged, match with boss on the sleeve pipe 4 connecting end inwalls with nut 7, on the inwall of nut 7 and sleeve pipe 3 connecting ends the internal thread that is complementary with sleeve pipe 3 one end outside threads is arranged, between sleeve pipe 3 and the sleeve pipe 4 seal washer 8 is arranged, during connecting tube, the tube wall outside, end of pipeline 1 and pipeline 2 is processed the uniform depression of 1-5 1-3 millimeters deep respectively, depression determines according to pipe thickness deeply, thickness of pipe wall, the cave is dark, tube wall is thin, the cave is shallow, and depression what according to the caliber decision, and the big depression of caliber is many, caliber is little, the cave is few, the number of depression and position are consistent with screw number and position on the sleeve pipe, and pipeline 1 is stretched in the sleeve pipe 3, with clamping screw 5 pipeline 1 are fixedlyed connected with sleeve pipe 3, make in the depression of clamping screw 5 precession pipelines 1 outer wall, with fastening screw nut 12 and dead.Pipeline 2 is stretched into sleeve pipe 4, with clamping screw 6 pipeline 2 is fixedlyed connected with sleeve pipe 4, make the depression of clamping screw 6 precession pipelines 2 outer walls interior, use fastening screw nut 13 and dead, internal thread with nut 7 is connected with the outside thread of sleeve pipe 3 again, drive in pipeline 1 and the sleeve pipe 4 in the sleeve pipe 3 pipeline 2 near, compress seal washer 8 therebetween, reach fastening, effect is tightly connected.
Embodiment 2:
The elbow connection (see figure 2) has sleeve pipe 3,4, clamping screw 5,6, fastening screw nut 12,13, nut 7,11, seal washer 8 and curved head body 9 constitutes, and with embodiment 1 difference is: increased a curved head body 9, nut 11 and seal washer 8, curved head body 9 two ends have the outside thread that is complementary with nut 7, nut 11 internal threads respectively, nut 7 is connected with curved head body 9 threaded one ends, and nut 11 is threaded with a body 9 the other ends, and 4 of curved head body 9 both ends of the surface and sleeve pipe 3 and sleeve pipes have seal washer 8 respectively.
Embodiment 3:
Tee union (see figure 3) and embodiment's 2 difference is: increase a nut 16, sleeve pipe 17, seal washer 8, clamping screw 15 and fastening screw nut 14, change curved head body 9 into three-way body 10, pipeline is all identical with embodiment 2 with the connecting means of sleeve pipe and sleeve pipe and nut, and nut is identical with the curved head body Placement among nut and three-way body connecting means and the embodiment 2.
