Abstract

The utility model relates to an expansion metal slip joint for plastic pipeline which is connected in series in the pipeline system. The utility model is characterized in that a sleeve is formed by connecting an inner pipe and an outer pipe; the inner pipe and the outer pipe can slide opposite to the axial direction; at least one O-shaped ring is arranged between the inner pipe and the outer pipe; and the port of the O-shaped ring is provided with an O-shaped loop; a connecting screw thread or flange which is connected with the pipeline system is arranged at the two ends of the inner pipe and the outer pipe and. The utility model has the advantages of compensating the expansion or shrinkage caused by the change of the temperature or medium, ensuring the normal operation of the pipeline system, making the pipeline system simple, safe, practical, economic, good looking and small occupied area, and decreasing construction cost. The utility model is suitable to various plastic pipelines used for water supplying construction cool water and hot.

Description

Plastic pipe expanding metal slip joint
The utility model relates in a kind of plastic pipe compensation and causes the annex that expands or shrink because of temperature or medium temperature change.
In construction project, hot water or cold water's supply system extensively adopts various plastic water pipes, because the linear expansion coeffcient of plastics is bigger 10~15 times than metal pipe, the amount of expanding with heat and contract with cold that produces when medium temperature changes in environment or pipe more than metallic conduit greatly, for guaranteeing the safe and reliable operation of water system, must take indemnifying measure in system, absorption system expands or contour projector.Usually, generally adopt the II type both at home and abroad, ring-like slip joint or utilize compensator arm measures such as pipeline knuckle turning, more than various compensation method compensation rates little, it is bigger to take up space, it is loaded down with trivial details to construct, and it is more that quantity is set, also not attractive in appearance, the engineering reflection is stronger, the engineering cost height wishes to select to adopt the pipe special annex in plastics hot and cold water feedwater piping, rationally solves these problems that occur in the engineering.
The purpose of this utility model provides a kind of plastic pipe expanding metal slip joint that is connected in the pipe-line system, and is simple, economical, attractive in appearance, compensate plastic pipe effectively and change expansion or the contour projector that causes because of temperature or medium temperature.
The technical solution of the utility model: plastic pipe expanding metal slip joint, the sleeve-shaped that has connecting head for two ends, it is characterized in that: sleeve pipe is socketed to form by interior pipe and outer tube, inner and outer pipe can slide to axial, be provided with at least one O shape ring between the inner and outer pipe, port is established O shape circle one, is provided with the connecting port that is connected with pipe-line system at interior pipe with the outer tube two end part.
Managing in above-mentioned and being provided with the connecting port that is connected with pipe-line system with the outer tube two end part is connecting thread or adpting flange.
Above-mentioned connecting thread can be selected internal thread or outside thread.
Pipe is short than outer tube in above-mentioned.
Above-mentioned O shape ring is teflon O shape ring or ethylene-propylene diene copolymer O shape ring.
Above-mentioned O shape circle is ethylene-propylene diene copolymer O shape circle or other rubber o-ring.
The transverse section of above-mentioned O shape circle or O shape ring is circle, rectangle or polygonal.
Working principle of the present utility model: plastic pipe expanding metal slip joint is connected in the pipe-line system, the interior pipe of knockdown metal material pipe box is short than outer tube, can endwisely slip between the inner and outer pipes, end between the inner and outer pipes is provided with one to twice teflon O shape ring, port is established ethylene propylene diene rubber O shape circle again one, expand or shrink when inner and outer pipe causes because of temperature or medium temperature change, when moving to axial, O type ring and O shape enclose sealing and reduce the effect of inner and outer pipe resistance to motion.For preventing that inner and outer pipe disconnects when the system works or pulls, the fastening anti-slip measure of connecting thread outside the inner and outer pipe port is equipped with pipe made in Great Britain can directly be connected with flanges such as pipe-line system pipe fitting and piping attachments with the internal thread of plastics embedded metal pipe or by the screw thread flange.
Advantage of the present utility model: this plastic pipe expanding metal slip joint is connected in series one with plastic pipe, can compensate because of temperature or medium temperature change expansion or the contraction that causes, guarantees the pipe-line system proper functioning, guarantees the safe transport hot and cold water; Make pipe-line system simple, practical, economical, reliable, attractive in appearance, save the space, reduce engineering cost.Be applicable to the various plastic pipes of Building Cooling water supply.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is the utility model embodiment one a structural representation;
Fig. 2 is the utility model embodiment two a structural representation.
Among the figure, pipe, 2-outer tube, 3-O shape ring, 4-O shape circle, 5-outside thread, 6-internal thread, 7-flange in the 1-.
Embodiment one: plastic pipe expanding metal slip joint, be socketed to form by interior pipe 1 and outer tube 2, interior pipe is short than outer tube, inner and outer pipe can slide to axial, be provided with twice teflon O shape ring 3 between the inner and outer pipe, port is established ethylene-propylene diene copolymer O shape circle 4 one, and the inner tube mouth has outside thread 5, outer tube port that internal thread 6 is arranged, with being threaded of pipe-line system.O shape circle or the transverse section be that transverse section circular, O shape ring is rectangle or polygonal.
Embodiment two: O shape circle adopts butyronitrile rubber O shape circle, O shape circle or O shape ring be in being embedded in the pipe groove or lock ring on inner pipe, interior pipe, outer tube terminal port flange 7 are connected with pipe-line system screw thread flange.
The specification of the utility model plastic pipe expanding metal slip joint has De20, seven kinds of specifications such as 25,32,40,50,63,75,90,110 grades.Inner and outer pipes end pipe screw thread has more than the G1 " 4 ", and the slip joint material can be selected SH-59 copper, stainless steel and other metal for use.
