Abstract
The utility model relates to a pipe movable joint, which comprises a segment of connecting sleeve pipe. The utility model is characterized in that the external side of the connecting sleeve pipe is provided with a pair of outer sleeve pipes, the inner diameter of one end of the outer sleeve pipes is the same with the inner diameter of the connecting sleeve pipe, the outer diameter of the other end of the outer sleeve pipes is the same with the outer diameter of the connecting sleeve pipe, two outer sleeve pipes are oppositely sheathed outside the connecting sleeve pipe, the butt joint part of the two outer sleeve pipes is provided with a connector, the connection part between the two outer sleeve pipes and the both ends of the connecting sleeve pipe is provided with a sealing ring. The utility model is convenient in installation and disassembly and needs no pull filaments for a connected pipe; the utility model can favorably solve the problem of heat expansion and cold contraction of pipes; besides, the utility model have low requirement on the length of the pipes during connection.
Description
The utility model relates to a kind of pipe movable connector.
In the pipework, the connection of pipeline is very frequent, main employing is pipe collar or loose joint at present, pipe need be pulled silking, the length of pipe will calculate very accurate, especially often needing the place of dismounting very inconvenient, also there is the cool problem that contracts of pipeline heat expansion in summer in winter in installation formality complexity at northern area.
The purpose of this utility model is to provide a kind of installing/dismounting easy, need not pull silk to the pipe that connects, and can better solve the pipe movable connector of the bloated shrinkage problem of pipeline thermal.
The utility model comprises one section adapter sleeve, it is characterized in that a pair of outer sleeve outside adapter sleeve, outer sleeve one end internal diameter is identical with the adapter sleeve internal diameter, the other end is identical with the adapter sleeve external diameter, two outer sleeves are placed in outside the adapter sleeve relatively, and joint is provided with link, and the joint at two outer sleeves and adapter sleeve two end part is provided with sealing ring.
Above-mentioned link can be established the butt joint screw thread by two outer sleeve joints and constitute; Also can constitute by the attaching nut that an outer sleeve is provided with on outside thread and another outer sleeve; Also can constitute by a pair of connection part that is respectively equipped with internal and external threads that is placed on two outer sleeves.
For increasing the encapsulation and the steadiness of the utility model connecting tube, above-mentioned outer sleeve two outer ends also can be established pullover, and pullover and outer sleeve joint is provided with sealing ring.
The utility model installing/dismounting is very easy, need not pull silk to the pipe that connects, and can better solve the bloated shrinkage problem of pipeline thermal, and when connecting tube length is required and can lower.
Face does not describe the utility model in conjunction with the accompanying drawings.
Fig. 1 is the utility model embodiment 1 a structural representation.
Fig. 2 is the utility model embodiment 2 a structural representation.
The utility model comprises one section joint sleeve (4), is provided with connected components at the two ends of sleeve pipe, and this assembly is a pair of outer tube (3), outer tube one end internal diameter is identical with the joint sleeve internal diameter, and the other end is identical with the joint sleeve external diameter, and two outer tubes overlap relatively Outside joint sleeve, and joint is provided with the docking screw thread, and the junction at two outer tubes and joint sleeve both ends is provided with sealing ring (2). For not relatively rotating between the internal and external casing when connecting pipe (1), one is provided with external screw thread in two outer tubes, another overcoat Internal thread on the pipe can be located on the attaching nut (5); Also can on two outer tubes, establish in addition one group of company that is provided with respectively internal and external threads Connected components (5,6). For increasing closure and the steadiness of the utility model connecting pipe, also can in above-mentioned outer tube two outer ends Pullover if (7), pullover and outer tube junction is provided with sealing ring.
Embodiment 1: with reference to Fig. 1, the butt joint screw thread in this example is located on two outer sleeves, and one outer sleeve one has internal thread, on the sleeve pipe outside thread is arranged in addition, and two outer sleeves directly connect.
Embodiment 2: compare with example 1, on the outer sleeve of this example outside thread arranged, be with an attaching nut on another outer sleeve, this attaching nut be provided with externally threaded outer sleeve and be connected.
Embodiment 3: with reference to Fig. 2, be with one group of link (4,5) on the outer sleeve in this example two outer outer sleeves are connected.
