Description
Technical field
The utility model relates to the Component of domestic water supply pipe, more specifically the supply pipe pipe joint that connecting pipeline is used in the pipe-line system of tubing such as a kind of crosslinked polyethylene.
Background technique
At present in the delivery (pipe) line system, some part always needs repairing or changes, and must pull down some part and repair or replace this moment.In the pipe-line system of using new chemical building materials crosslinked polyethylenes (PEX), modified polypropene (PP-R), aluminium-plastic composite pipe, there is not the part of dismounting flexibly in the original fitting, dismounting inconvenience in the time of can causing the pipe-line system maintenance.See also Fig. 1, the pipe joint in the original fitting is a monolithic construction, and one section outer wall of this pipe joint 1 is provided with a plurality of steps 11, and its middle part outer wall is made as hexagon 12, and it is cylindrical 13 that its another section outer wall is made as, and the inwall of pipe joint 1 is provided with screw thread 14.When being linked to be pipe network system at pipe fittings such as the affixed water meters in pipe joint two ends, water meter or pipe fitting that with the passing of time damage is arranged, in the time of need changeing, because pipe joint is whole, can't take apart, also can't unload water meter or pipe fitting that two ends connect,, cause pipe-line system maintenance dismounting inconvenience often to cut off pipe or to destroy the purpose that pipe fitting reaches the maintenance pipe-line system.
Summary of the invention
The purpose of this utility model is the shortcoming that will solve the pipe joint existence of adopting in the present pipe-line system, provides a kind of pipe attachment portion and internal thread attachment portion are made as two parts, and the dismounting flexible and convenient again can matching used supply pipe pipe joint.
The technical solution of the utility model is achieved in that a kind of supply pipe pipe joint, is characterized in, comprises pipe joint, movable joint, sheathed pipe joint in movable joint; Described pipe joint outer wall end periphery is provided with the connection step; One section of described movable joint outer wall is made as hexagon, and another section outer wall is made as cylindrical, and the movable joint inwall is provided with internal thread, and next-door neighbour's screw thread edge is provided with positioning step.
Above-mentioned supply pipe pipe joint, wherein, the connection step of described pipe joint outer wall end periphery next-door neighbour is provided with the water pipe that is lower than this step and is nested with step.
Above-mentioned supply pipe pipe joint, wherein, the described pipe joint outer wall the other end also is provided with a plurality of steps that are lower than above-mentioned two steps.
Above-mentioned supply pipe pipe joint, wherein, described pipe joint outer wall is provided with 3 at least to top bar.
The utility model is owing to adopt above technological scheme, the joint of integral body is divided into two movable parts, one section affixed pipe of pipe joint, the other end is set in the movable joint, flexibly connects with movable joint, and the screw thread that is provided with in the movable joint can connect part with the pipe fitting screw thread that disposes in it, can be for convenience detach, thereby change any accessory in the pipe network piecemeal, installation connects easy, dismantles easy to maintenance.
Description of drawings
Concrete structure of the present utility model is further provided by the following drawings and embodiment.
Fig. 1 is existing integrated pipe joint structure schematic representation.
Fig. 2 is the utility model supply pipe pipe joint structure schematic representation.
Embodiment
See also Fig. 2, supply pipe pipe joint 2 of the present utility model comprises: pipe joint 21, movable joint 22, pipe joint 21 outer walls are provided with a plurality of steps, pipe joint outer wall end periphery is provided with and connects step 211, the connection step next-door neighbour of pipe joint outer wall end periphery is provided with the step that is nested with water pipe 212 that is lower than this step, and another section of pipe joint outer wall also is provided with a plurality of steps 213 that are lower than above-mentioned two steps; Movable joint is made as hexagon 221 outward for 22 1 sections, is used to tighten connecting tube, and it is cylindrical 222 that another section outer wall is made as, and the inner wall edge of this section is provided with step 223, and next-door neighbour's step 223 is provided with internal thread 224; The pipe fitting that is used for connecting pipeline, pipe joint 21 is set in the movable joint 22, the connection step 211 of pipe joint outer wall end periphery is set in the step 223 of movable joint 22 inwalls one end and offsets, pipe joint 21 and movable joint 22 are movably connected, step 212, the 213 part strings that pipe joint 21 outer walls are provided with are crossed movable joint 22 and are exposed outside movable joint 22, but pipe joint outer wall overcoat connects aluminium-plastic composite pipe 4 to water pipe step 212.
When using, the connection step 211 of pipe joint outer wall end periphery is set in the step 223 of movable joint 22 inwalls one end and offsets, and flexibly connects, and step 212, the 213 part strings that pipe joint 21 outer walls are provided with are crossed movable joint 22 and exposed outside movable joint 22.Pipe joint 21 outer walls are provided with a plurality of steps, can strengthen the friction with composite pipe 4, strengthen connecting fastness, are inserted in aluminium-plastic composite pipe 4 to step 212, are nested with on the outer wall of the aluminium-plastic composite pipe 4 of pipe joint 21 with snap ring 3.The internal thread 224 that is provided with in the movable joint 22; Pipe fitting screw thread bolt with in the pipeline connects accessories such as aluminium-plastic composite pipe or water meter again.Overhaul parts in the pipeline when need, turn on movable joint 22, just the crosslinked polyethylene or the accessory maintain and replaces such as modified polypropene, aluminium-plastic composite pipe or water meter of detachable this section.
The utility model structural design novelty, reasonable, it is easy to adopt the supply pipe pipe joint to carry out the pipeline connection, and dismounting is easy to maintenance.
