Abstract

The utility model relates to a flexible connector for a fluid pipeline, and is particularly suitable for the connection of pipelines of the solar water heater collector. Two or more than two annular troughs are arranged at the inner wall of a non-metallic pipe with certain flexibility; at least one glue-injecting hole along the radial direction of the non-metallic pipe arranged at the bottom of each annular trough is communicated with the outer wall of the non-metallic pipe. While in use, the two corresponding pipe-mouths of two rigid fluid pipelines which need to be connected are embedded at two ends of the non-metallic pipe; each rigid fluid pipe-mouth is covered by at least one annular trough at the inner wall of the non-metallic pipe. Each glue-injecting hole is cast-with-pressure with sealant; after the sealant is solidified, a weathering-resistant and flexible seal ring is formed between the rigid fluid pipeline outer wall and the non-metallic pipe inner wall. The utility model has the advantages that water leakage problem of the joint caused by the principle that metal expands on heating and contracts on cooling is solved.

Description

The flex link that is used for fluid line

Technical field: the utility model relates to a kind of flex link that is used for fluid line, is specially adapted to the connection of heat collectors for solar water heater pipeline enclosure.

Background technique: outdoor two rigidity fluid lines, as often need being interconnected as the mouth of pipe of sebific duct between the metallic fluid line by the certain flexible nonmetallic pipe of tool with them.In the solar water heater, be interconnected with the mouth of pipe of rubber pipe between the aluminum water pipe of heat collector them.Though the inclusion place of rubber pipe and aluminum pipe compresses with the larynx hoop, different with the thermal expansion coefficient of rubber because of aluminium, temperature change can cause joint water clock water round the clock, and this becomes puzzlement hard nut to crack so far.

Summary of the invention: in order to overcome the shortcoming of prior art, the utility model provides a kind of flex link that is used for fluid line, even its joint of variation of ambient temperature can water clock water yet.

The technical scheme in the invention for solving the technical problem is: the inwall of the certain flexible nonmetallic pipe of tool is processed with two or more circular groove, and the bottom land of each circular groove is communicated with the outer wall of this nonmetallic pipe along this nonmetallic pipe hole for injecting glue radially by one at least.

Use of the present utility model: the two corresponding mouths of pipe of two rigidity fluid lines that will connect embed the two-port of nonmetallic pipe respectively, and the mouth of pipe of each rigidity fluid line is surrounded by a circular groove of nonmetallic pipe inwall at least.In each hole for injecting glue, press to irritate sealer, when treating that hole for injecting glue has the sealer of filling to overflow, show to be full of the filling sealer in the circular groove, stop injecting glue and compress with the larynx hoop.Behind the sealing glue solidifying, just generate the weather-proof seal ring of elasticity that makes the two good bond between rigidity fluid line outer wall and the nonmetallic pipe inwall.

The beneficial effects of the utility model are to have solved to expand with heat and contract with cold to cause the hard nut to crack of joint water clock water.

Description of drawings: Fig. 1 looks cross-sectional view for embodiment's master.

Fig. 2 is an A-A cross-sectional view among Fig. 1.

Embodiment: see a specific embodiment shown in Fig. 1 and 2.This embodiment is used between the aluminum water pipe of solar water heater heat collector.The inwall of rubber pipe 1 is processed with two circular grooves 2, and the bottom land of each circular groove 2 is communicated with the outer wall of pipe 1 by three hole for injecting glue 3 that are mutually 120 degree angles.During use, the two corresponding mouths of pipe of two heat collector aluminum water pipes 4 (for the upper and lower collector of heat collector) that need are connected embed the two-port of rubber pipe 1 respectively, and the mouth of pipe of each water pipe 4 is surrounded by a circular groove 2.In each hole for injecting glue 3, press to irritate extraordinary sealer, when treating that hole for injecting glue 3 is overflowed the sealer of 2 cm thicks, stop injecting glue and compress with larynx hoop 5.Behind the sealing glue solidifying, just generate the weather-proof seal ring of elasticity between aluminum water pipe 4 outer walls and rubber pipe 1 inwall, facts have proved, even the ambient temperature acute variation, this joint can water clock water yet.

Above embodiment is only in order to be further described the utility model, and scope of the present utility model is not subjected to the limitation of illustrated embodiment.

Claims

1, a kind of flex link that is used for fluid line, it is characterized in that: the inwall of the certain flexible nonmetallic pipe of tool is processed with two or more circular groove, and the bottom land of each circular groove is communicated with the outer wall of this nonmetallic pipe along this nonmetallic pipe hole for injecting glue radially by one at least.

2, as the said coupling of claim 1, it is characterized in that: the inwall of rubber pipe (1) is processed with two circular grooves (2), and the bottom land of each circular groove (2) is communicated with the outer wall of rubber pipe (1) by three hole for injecting glue (3) that are mutually 120 degree angles.
