Abstract
The utility model belongs to the design of the high pressure resistance plastic joint for a pipeline. The designed plastic joint for a pipeline of the utility model is composed of a rubber sealing ring, a screw nut sleeve with a groove, an external screw sleeve, a spacer and a metal ring with an internal screw. The high pressure resistance plastic joint for a pipeline has the advantages of simple structure, firm connection and good sealing performance. The high pressure resistance plastic joint for a pipeline can bear the high pressure of 8 to 10 megapascals; the interface is not easy to fall off, and the high pressure resistance plastic joint for a pipeline can be widely used for the connection of the oil-gas-water conveying device in an oil field.
Description
The utility model belongs to high pressure resistant plastics pipe interface design.
Chinese patent 95214818.8 " crosslinked polyethylene pipe interface " is to adopt the threaded female cover that has a groove, at threaded female cover two ends interior tilted conical surface is arranged, and coincide with the rubber seal that has outer tilted conical surface.During installation, successively with thread jacket, pad is enclosed within on the crosslinked polyethylene pipe, will need an end of connecting tube to insert in the groove of threaded female cover then, and external thread sleeve, pad, sealing rubber ring adopt with female cover and be threaded.Rely on the pressing friction connecting pipeline of seal ring and tube wall.
When conveyance fluid, the pipe joint place can produce the power of horizontal vertical both direction.When longitudinal force increased, the reaction force of rubber ring was strong more, and seal action is good more; But when lateral pressure during greater than the frictional force of rubber ring and pipeline outer wall, pipeline will be deviate from from interface, cause pipeline to interrupt.
The purpose of this utility model provides a kind of by the metal ring that has internal thread, rubber seal, groove threaded female cover, the interface that external thread sleeve and pad are formed.The internal thread metal ring directly is tightened in the plastic tube end.Compress metal ring by external thread sleeve, pad, rubber ring, interface is unlikely when higher lateral pressure comes off, can bear 8～10MPa with upward pressure.
Action principle accompanying drawings of the present utility model is as follows:
Fig. 1 is high pressure resistant plastic pipe interface schematic representation, the threaded female cover 1 that has groove among the figure, there is interior tilted conical surface at its two ends, coincide with the rubber seal 2 that has outer tilted conical surface, successively external thread sleeve 4, pad 3, rubber seal 2 are enclosed within on the termination of plastic tube during installation, the metal ring 6 that will have internal thread then is tightened in pipe end, directly inserts in the groove of threaded female cover and tightens.Another root pipe that will connect in the same way connects.When external thread sleeve and threaded female cover screwing, promote rubber seal by pad, make tilted conical surface tight connecting in its outer tilted conical surface and the threaded female cover, and utilize the elasticity of rubber seal that the inner face of seal ring and pipe outer wall are sealed fully, compress metal ring 6 simultaneously again.Can play sealing and fastening effect like this, utilize rubber seal to block the metal ring that is screwed in pipe end simultaneously, be unlikely when making interface bear high pressure and come off.
Claims (1)
1. high pressure resistant plastic pipe interface, it is the threaded female cover 1 that has groove, there is interior tilted conical surface at its two ends, coincide with the rubber seal 2 that has outer tilted conical surface, during installation, successively external thread sleeve 4, pad 3, rubber seal 2 are enclosed within on the termination of plastic tube, it is characterized in that the metal ring 6 that will have internal thread is tightened in pipe end, directly will insert in the groove of threaded female cover and tighten.
