Abstract
The utility model relates to a PP-R water supply connecting pipe which comprises a pipe material and an external threaded pipe sleeve, wherein the external threaded pipe sleeve consists of a copper embedded element and an external threaded pipe sleeve plastic element; the copper embedded element is embedded in the external threaded pipe sleeve plastic element; the external threaded pipe sleeve plastic element and the pipe material are fixedly connected together through a hot melting bearing and insertion technology; the periphery of the end of the copper embedded element embedded in the external threaded pipe sleeve plastic element is provided with two dovetail grooves, and the inner side of the end of the copper embedded element is provided with a rubber seal ring groove; and the other end of the copper embedded element is provided with an external thread. The PP-R water supply connecting pipe provided by the utility model is non-toxic and sanitary and has the beneficial effects of temperature preservation, energy conservation, good heat resistance, long service life, convenience in installation, and material recycling; the PP-R water supply connecting pipe is made from imported raw materials by imported devices, and the quality is superior; the pipe fitting is provided with reinforcing ribs in appearance, and thus the pipe fitting strength is high; and the copper embedded element is provided with two dovetail grooves and a rubber seal ring groove, and thus water leakage and water seepage are eradicated.
Description
Technical field
The utility model relates to the water connecting tube, mainly is a kind of PP-R feedwater connecting tube that is used for water, gas conveying.
Background technique
PP-R feedwater connecting tube in the market is owing to price factor, and the raw material and the process equipment that cause manufacturer to adopt are relatively backward, do not possess insulation, resistance to heat; PP-R feedwater connecting tube causes the hardness of pipe fitting not high because design is unreasonable in addition, occurs the infiltration phenomenon of leaking sometimes.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned existence, and the PP-R feedwater connecting tube of a kind of heat preservation energy-saving, better heat-resisting property is provided.
The purpose of the utility model is accomplished through following technological scheme; It comprises tubing, outside thread pipe box; Described outside thread pipe box is made up of copper insert and male-pipe sleeving plastic spare; This copper insert is embedded in the male-pipe sleeving plastic spare, and this male-pipe sleeving plastic spare is fixedly connected through the thermofusible spigot technology with between tubing.
As preferably, described periphery at the copper insert end that is embedded in male-pipe sleeving plastic spare place is provided with the twice dovetail groove, and the inboard is provided with the rubber seal ring recess one; This copper insert end in addition is provided with outside thread.
The beneficial effect of the utility model is: nontoxic, health; Heat preservation energy-saving, better heat-resisting property, long service life, easy for installation, the recyclable utilization of material; Adopt imported raw material and import equipment to be made, quality is more excellent; The pipe fitting profile has reinforcing rib design, makes pipe fitting intensity higher, and copper insert adopts two road dovetail grooves to add one rubber seal ring recess design, the infiltration of stopping to leak.
Description of drawings
Fig. 1 is that the utility model master looks cross-sectional view.
Fig. 2 is the forming stereo structural representation of the utility model.
Label in the accompanying drawing is respectively: 1, tubing, 2, the outside thread pipe box, 21, copper insert, 22, male-pipe sleeving plastic spare, 211, dovetail groove, 212, the rubber seal ring recess, 213, outside thread.
Embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: like accompanying drawing 1, shown in 2; Comprise tubing 1, outside thread pipe box 2; Described outside thread pipe box 2 is made up of copper insert 21 and male-pipe sleeving plastic spare 22; This copper insert 21 is embedded in the male-pipe sleeving plastic spare 22, and this male-pipe sleeving plastic spare 22 passes through the thermofusible spigot technology with 1 of tubing and is fixedly connected.Described periphery at copper insert 21 ends that are embedded in male-pipe sleeving plastic spare 22 places is provided with twice dovetail groove 211, and the inboard is provided with rubber seal ring recess 212 one; This copper insert 21 end in addition is provided with outside thread 213.When this tubing body surface was provided with a red colour band line, be hot-water line this moment; When tubing body surface did not have the colour band line, be cold water pipe this moment.
The utility model is applied to: the cold and hot water supply system of building comprises central heating system; Heating system in the building, comprise floor, wallboard and panel type heating system; Purified water supply system capable of direct drinking; Central authorities' (concentrating) air-conditioning system; Industrial pipe-line systems such as conveying or discharging chemical mediator; Be used for the pipe-line systems such as gas circuit that cylinder transmits.
Except that the foregoing description, all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
