Abstract
A novel composite connecting pipe is improved from the conventional one by arranging a groove (1) at the connecting joint of the composite connecting pipe wall, and arranging a groove (2) at the top of the groove (1). Residual PPR or PE from heat-melting can be held in the groove (2) to eliminate residual heat-molten material outside the connecting pipe, so that good appearance of the composite connecting pipe is ensured and sealing performance is improved. The utility model can be used in various connections such as elbow connection, triton connection, four-way connection, and different size connection.
Description
Technical field:
The utility model relates to a kind of improvement of composite connecting pipe spare.
Background technique:
The type of composite connecting pipe spare in the market, kind, brand are all a lot, but these composite pipe fittings all are PPR or PE material, and the concrete structure of these pipes all is that the internal layer of dual single structure is PPR or PE material, and skin is the plastic-aluminum structure.This class composite connecting pipe should not corrode owing to durable in use, has obtained the extensive approval in market, is widely used in building hot water or cold water, gas pipeline system; Direct drinking pipe, road system; Central air-conditioner cool and hot water pipe system; Industry, medicine, chemical liquid, food liquid pipeline system.The joint of these pipelines all is to connect with hot melt, and the joint of composite connecting pipe often is impregnated with remaining PPR of hot melt or PE material in this case; These materials that ooze in the joint often have a strong impact on the attractive in appearance of composite connecting pipe, and this problem has perplexed the industry for a long time, as shown in Figure 1, 2.
The model utility content:
The utility model has been developed a kind of NEW TYPE OF COMPOSITE connecting tube, and it has hot melt connection back and does not have remaining hot melt material in the joint.Composite connecting pipe of the present utility model is provided with groove 1 in the joint of tube wall, is provided with groove 2 again on the top of groove 1.This composite connecting pipe of the present utility model, top at groove 1 is provided with groove 2 again, groove 2 can hold the remaining PPR or the PE material of hot melt, remaining PPR or PE wall that Fig. 4 peels off titanium alloy pack in Fig. 3, tube wall with titanium alloy withstands Fig. 3 groove mouth, just do not have unnecessary hot melt material in the outside of connecting tube like this, guaranteed the beautiful shape of composite connecting pipe, increased sealability simultaneously again.The utility model can be applied to various occasion, comprises that elbow connection, threeway connection, four-way connect, CONCENTRIC REDUCER connects or the like.
Description of drawings:
Fig. 1 is the structural representation that the joint of existing composite connecting pipe is impregnated with hot melt material,
Fig. 2 is the sectional view of existing composite connecting pipe, and Fig. 3 is a structural representation of the present utility model,
Fig. 4 is the structural representation after connecting.
Embodiment:
As shown in Figure 3, the composite connecting pipe of this embodiment is provided with groove 1 in the joint of tube wall, is provided with groove 2 again on the top of groove 1.This composite connecting pipe of the present utility model, top at groove 1 is provided with groove 2 again, groove 2 can hold the remaining PPR or the PE material of hot melt, Fig. 4 is the structural representation after connecting, remaining PPR or the PE wall that titanium alloy is peeled off packs in Fig. 3 in this case, withstanding Fig. 3 mouth with the tube wall of titanium alloy does not just have unnecessary hot melt material in the outside of connecting tube like this, has guaranteed the beautiful shape of composite connecting pipe, has increased sealability simultaneously again.This embodiment can be applied to various occasion, comprises that elbow connection, threeway connection, four-way connect, CONCENTRIC REDUCER connects or the like.
Claims (1)
1, a kind of NEW TYPE OF COMPOSITE connection pipe fitting is characterized in that it is provided with groove (1) in the joint of tube wall, be provided with groove (2) again on the top of groove (1).
