Abstract
The utility model relates to a connecting ring for plastic pipe fitting(PPR, plastic aluminum PPR), which is formed by the melting jointing of one pipe fitting and another pipe fitting. The connecting ring for plastic pipe fitting is characterized in that a lantern ring is sheathed in the inner wall of the pipe fitting. The connecting ring for plastic pipe fitting has the advantage of simple structure, convenient use, safety and reliability, cost saving,and water discharge improving.
Description
Technical field
The utility model relates to the plastic pipe that is used for needing hot melt to connect (PPR, mould aluminium PPR) connecting ring, a kind of collar that uses when connecting plastic tube and pipe fitting.
Background technique
Existing environmental protection shape building materials plastic water pipe and its pipe fitting plastics such as (directly) elbows be when being connected, must be with after the inwall heating of hot-melting machine with the outer wall of tubing and pipe fitting, and the connection of tubing insertion pipe fitting.When hot-melting machine heating tubing, pipe fitting, temperature variation is arranged, so time that must their fusings of strict control during the heat fused pipe part.When fusing when not enough, pipe fitting, tubing connect not firm, produce water clock, and melting time is when long, and tubing is yielding, the current of whole pipe are diminished or block.Because pipe fitting is with after tubing is connected, the connection result of whole pipe is sightless, so problem that occurs on the frequent check connection result of palpus and the difficult discovery in the back interconnection technique where that has problems, the hidden danger that engineering is produced also is difficult for finding, and producer is when producing tubing, the corresponding thickness of thickening tubing, not yielding when making the tubing fusing, wasted material, but reduced the internal diameter of tubing accordingly, the water flow of pipeline is reduced.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, provides a kind of making on the time of heat fused tubing to prolong relatively, and the fusing mouth is neat; It is more neat that tubing inserts pipe fitting welding rear port, welds more reliable plastic pipe connecting ring.
The purpose of this utility model is to realize like this; It is formed by connecting by a pipe fitting and the fusing of another pipe fitting, it is characterized in that being inserted on the inwall of pipe fitting a collar.
Because the utility model is to be inserted in a collar on the inwall of plastic tube, and the temperature of hot-melting machine molten plastic tubing can't melt the collar, when the outer wall of plastic tube heats on hot-melting machine, after time is long, the plastic tube fusing deliquescing of soldering opening, at this moment the collar just plays the effect to plastic tube inwall cooling and setting, and the interface inwall that makes plastic tube maintains the original state and its outer wall fully melts.It is good, firm and indeformable to connect rear port, so the utility model can reach the purpose of drafting.
Below in conjunction with accompanying drawing, the utility model is specifically described (but not being to scope restriction of the present utility model)
Description of drawings
Fig. 1 is a structural profile schematic representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is formed by connecting by pipe fitting (1) and pipe fitting (2) fusing, it is characterized in that being inserted on the inwall of pipe fitting (2) collar (3).After using the utility model product, can guarantee the quality of connection of pipe fitting pipeline, simultaneously producer also can to produce tube wall thinner, the pipe fitting tubing that internal diameter is bigger has been saved cost, has improved water flow.
Claims (1)
1, a kind of plastic pipe connecting ring is formed by connecting by pipe fitting (1) and pipe fitting (2) fusing, it is characterized in that being inserted on the inwall of pipe fitting (2) collar (3).
