Abstract
The utility model discloses a multi-through pipeline telescopic connector which can be used for splicing a multi-branch parallel-connecting pipeline system conveniently, and length changing amount can be automatically compensated and absorbed. The multi-through pipeline telescopic connector comprises a straight-through main pipe, a first stem pipe connector, a second stem pipe and a multi-through pipeline body composed of more than two branch pipes which are provided with telescopic connectors. The multi-through pipeline telescopic connector is mainly used for splicing various parallel-connecting pipeline systems.
Description
Technical field
The utility model relates to a kind of pipe coupling, particularly the joints of threading a pipe more.
Background technique
Pipe-line system is widely used in daily life and industry, and wherein various pipe couplings play very important effect.Although as a rule, with existing pipe coupling, just can splice easily as required various required pipe-line systems, but in reality, also have some places to need parallel pipeline system, as plate solar collector and radiator, by existing pipe coupling splicing multiple branch circuit parallel pipeline system, have any problem.When splicing multiple branch circuit parallel pipeline system, many arms between two mains connect very inconvenient, and the length change that each arm causes because expanding with heat and contract with cold also inconvenience solves.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of expansion joint of threading a pipe is provided more, can splice easily multiple branch circuit parallel pipeline system, and auto-compensation absorbs the length change that each arm causes because expanding with heat and contract with cold with it.
In order to solve the problems of the technologies described above, the utility model has adopted following technological scheme:. a kind of expansion joints of threading a pipe more, by straight-through main, main joint first, main joint second and two above arms, form the body of threading a pipe, described arm is provided with expansion joint more.
Described expansion joint can adopt traditional slip joint, as Bellows expansion joint, sleeve pipe slip joint etc.
The utility model is all right: described expansion joint is comprised of expansion joint body, seal ring, extruding decorative cover, described expansion joint body and the described body of threading a pipe are fixedly linked more, described expansion joint body is provided with and is flexibly connected squeezing unit with described extruding decorative cover, and described seal ring is connected with described expansion joint body under the extruding that is flexibly connected squeezing unit.Described flexible connection squeezing unit can be flexibly connected squeezing unit with flange, also can adopt the squeezing unit that is threaded.Both the internal thread of the described squeezing unit that is threaded can be located to described extruding decorative cover one end, form internal thread extruding decorative cover, and the outer silk of the described squeezing unit that is threaded is located to described expansion joint body one end, form outer silk expansion joint body, also the outer silk of the described squeezing unit that is threaded can be located to described extruding decorative cover one end, form outer silk extruding decorative cover, and the internal thread of the described squeezing unit that is threaded is located to described expansion joint body one end, form internal thread expansion joint body.The described body of threading a pipe can adopt plastic materials more, and described expansion joint body adopts metallic material.Described plastics can be PPR materials, can be also PVC materials.
Compared with prior art the utility model has the advantages that: two relative threading a pipe, between expansion joint, can connect easily many branch roads more, thereby be easily spliced into multiple branch circuit parallel pipeline system, this system energy auto-compensation absorbs the length change that each arm causes because of the reason such as expand with heat and contract with cold.
