Abstract
The utility model provides an extension pipe joint which comprises a main body, an adjusting pipe and sealing rings. The extension pipe joint is characterized by further comprising a joint, wherein one end of the joint is sleeved on the main body and fixedly connected with the main body, the other end of the joint is sleeved on the adjusting pipe, annular grooves are arranged on the joint, and the sealing rings are arranged in the annular grooves and are attached with the outer wall of the adjusting pipe. Due to the fact that the joint is installed outside the main body and the adjusting pipe, the adjusting pipe is provided with mobile spaces, a problem of expanding with heat and contracting with cold of a pipeline is solved, a thread structure and a plurality of parts are saved, and the extension pipe joint is simple in structure, easy to install and low in cost. A plurality of annular grooves and sealing rings are arranged, sealing performance is improved, the number of the sealing rings can be selected appropriately according to sealing performance requirements of various pipelines, and application range is wide. The main body, the adjusting pipe and the joint are all formed by acrylonitrile butadiene styrene (ABS) which is provided with heat resistance and low temperature resistance, stable in size and small in temperatures change volume, and therefore the sealing performance of the extension pipe joint is improved and the length of the extension pipe joint is reduced.
Description
Technical field
The utility model belongs to the connection pipe fitting field, relates in particular to a kind of pipe expansion joint.
Background technique
In daily life, the pipelines such as transport of water, gas are absolutely necessary.Pipeline in the past adopts metallic conduit more, and metallic conduit exists price height, the shortcoming such as perishable.Along with the continuous research and development of new material, plastic tube because of its corrosion resistance and good, cheaply apply in the various pipes more and more widely.But there is the phenomenon of expanding with heat and contract with cold in plastic tube heat, and causes easily the pipe bending distortion, affects its normal use.Chinese patent 200610050786.3 discloses " a kind of expansion pipe joint ", comprise tube body, regulating nut, it is characterized in that: described tube body is provided with interface, the interface internal surface is provided with internal thread, be shaped with through hole in the middle of the described regulating nut, its outer surface is provided with the outside thread that matches with internal thread, is lined with seal ring between interface inner end and regulating nut end, and tube body, seal ring and regulating nut inner sleeve have one section vertically adjutage of sliding extension.Though this patent has realized the automatic adjusting of pipe coupling length, but its complex structure, difficulty of processing large, be difficult for assembling, finished product is higher and sealability is relatively poor.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of pipe expansion joint, comprise main body, adjutage, seal ring, characterized by further comprising joint, joint one end is sleeved on the described main body and with described main body and is fixedly connected with, the other end is sleeved on the adjutage, and joint is provided with circular groove, and described seal ring is positioned at circular groove and fits with the adjutage outer wall.
The quantity of described circular groove is 1-3, and identical with the quantity of described seal ring.
The material of described joint is ABS.
The material of described main body is ABS, and the material of described adjutage is ABS.
The beneficial effects of the utility model are: erection joint outside main body and adjutage, for adjutage provides mobile space, solved well the problem of expanding with heat and contract with cold of pipeline, saved worm structure and a plurality of parts, simple in structure, install easily, cost is lower; Be provided with a plurality of circular grooves and seal ring, improved sealability, can require to select suitable seal ring quantity, applied range according to the sealability of different pipelines; Main body, adjutage, joint all adopt the ABS material to make, and impact resistance, heat resistance, lower temperature resistance, chemical resistance are good, and dimensionally stable, and the amount of expanding with heat and contract with cold is little, has improved the sealability of this joint, has reduced the length of this joint.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Among the figure, 1, main body; 2, adjutage; 3, seal ring; 4, joint; 5, circular groove.
As shown in Figure 1, joint 4 one ends are sleeved on the main body 1 and with main body 1 and are fixedly connected with, and the other end is sleeved on the adjutage 2, and joint 4 is provided with a circular groove 5, and seal ring 3 is positioned at circular groove 5 and fits with adjutage 2 outer walls.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
