Abstract
The utility model relates to serial unthreaded pipeline connections, which are especially applied to the pipelines connection of water, gas and oil under the pressure of 8 kg/cm+[2]. When the pipeline connections are installed, the end parts of pipes need not to be made into the screw thread to make screw connection, the user only needs to cut the pipes according to the required length. The pipes are inserted in the connections, and then, nuts of both ends of the connections are screwed up. The utility model has the advantages of reasonable structure, simple operation and repair and use. The serial unthreaded pipeline connections provide very convenient condition for disassembling the pipeline.
Description
The utility model is a kind of novel coupling arrangement on the pipeline, is specially adapted to 8kg/cm
2Water below the pressure, the connection of gas and oil pipeline.
The pipe joint of domestic general use at present, need when mounted with coupled pipe on demand length cut, spin after again the end being made screw thread and adding gasket coating, or after adding sealing gasket between two flanges, use bolton, cumbersome to using maintenance, detaching pipelines, efficient is lower, and labor intensity is big.
The purpose of this utility model is to provide a kind of rational in infrastructure, safe and reliable, simple to operate, and repair demolition is pipe joint easily.
Task of the present utility model is achieved in that it is made up of connecting tube and nut, seal ring.Connecting tube has end, externally threaded two ends and is shaped on the inclined-plane, and two ends are furnished with nut with the level, and seal ring is equipped with at the step place of nut, and distortion is shunk and held pipe tightly by seal ring, reaches joint and pipe sealing purpose.
Details of the present utility model is provided by following examples and accompanying drawing thereof:
Fig. 1 is a ssembly drawing of the present utility model.
In conjunction with the accompanying drawings: there is screw thread at connecting tube 1 two ends, screw on nut 2, are lined with seal ring 3 between the two, and coupled pipe 4 is inserted in the connecting tube 1.Pipeline does not need that coupled tube end is made screw thread when installing and spins, only need with coupled pipe on demand length cut, insert in the connecting tube 1 of this joint, the nut with two ends screws again.Connecting tube 1 has to justify in the end, externally threaded two ends the inclined-plane of making, and when rotation has the nut 2 of step, promotes and force seal ring 3 distortion to be shunk to fill in the tight inclined-plane, reaches the connection purpose and hold coupled pipe 4 tightly.
Coupled pipe can have following specification:
1, welded pipe: 1/4 ", 3/8 ", 1 ", 1 1/4 ", 1 1/2 ", 2 "
2, seamless steel pipe: φ 5～60mm(external diameter)
That the utility model kind has is straight-through, threeway, four-way, elbow and various forms of reducer union.
Claims (2)
1, serial screw-thread-free pipe joint, especially for novel coupling arrangement a kind of on the pipeline, this device has connecting tube 1, nut 2, seal ring 3, it is characterized in that: connecting tube 1 has end, externally threaded two ends and is shaped on the inclined-plane, two ends are furnished with nut 2 with the level, and seal ring 3 is equipped with at the step place of nut 2.
2, pipe joint according to claim 1 is characterized in that it has straight-through, threeway, four-way, elbow and various forms of reducer union.
