Description
Technical Field
The utility model belongs to the technical field of the pipeline, especially, relate to a raceway of taking socket joint formula male and female joint.
Background
In the prior art, fluid transportation pipelines mainly include the following: ordinary nodular cast iron pipeline, carbon steel pipeline, prestressed concrete pipeline, PE pipe etc. above-mentioned pipeline's bearing capacity, corrosion resistance, resistance to external force destruction are all not good enough, some special transportation pipelines, for example: at present, 90% of pollution of drinking water comes from the pipeline, so that the requirement on the performance of the drinking pipeline is higher, and although the performance of the stainless steel pipeline is higher, the cost is high, and the long-distance transportation is not facilitated.
Furthermore, a plurality of composite steel materials are developed, which mainly comprise a lining type composite pipe and a bonding type composite pipe, for example, the Chinese patent 'composite stainless steel pipe' with the publication number of 2351647Y is used as an outer pipe, and then the outer pipe of the stainless steel is lined with a lining pipe made of plastics or iron sheets, the lining type composite stainless steel pipe combines the excellent performance of the stainless steel and the characteristic of low cost of the lining pipe made of plastics or iron sheets, but the lining type composite pipe is not suitable for the transportation of large-caliber pipelines, the base layer and the lining composite layer are easy to separate, and the welding between the pipelines is very troublesome; the other type of the bonding type composite pipe is made of composite stainless steel plates as in the Chinese patent with the publication number of CN2351272Y and composite stainless steel decorative plates as in the Chinese patent with the publication number of CN201310168Y, and the structure of the bonding type composite pipe is mainly characterized in that a layer of plates made of other materials is compounded on the basis of the stainless steel plates in a bonding mode, which is also the main compounding mode of the composite plates on the market at present; in addition, a composite pipeline formed by pressing double-layer metal is similar to an adhesive composite pipe and a lining composite pipe, is not suitable for large-diameter pipelines, and is not firm in connection with a base layer and easy to separate.
Therefore, the patent with the publication number of CN103727322B discloses an integrated stainless steel-carbon steel composite pipe and a preparation process thereof, wherein the pipeline is designed into a four-layer structure which comprises a stainless steel layer, a mixed layer of stainless steel and carbon steel, a carbon steel layer and a coating layer in sequence, wherein the mixed layer of stainless steel and carbon steel is smelted into an integrated structure through metallurgy, and meanwhile, the mixed layer of stainless steel and carbon steel forms an integrated structure with the stainless steel layer and the carbon steel layer respectively, compared with the bonding, lining and pressing in the prior art, the three layers are connected more firmly and are not easy to separate, and the thickness ratio of the stainless steel layer to the carbon steel layer is only 1: 10, compared with the traditional cast iron pipeline, stainless steel pipe and PE pipe, the integrated stainless steel-carbon steel composite pipe has better performance and lower price. However, there are problems with this type of tubing when connected. In the process of pipeline laying, the existing connection mode mainly comprises nut connection and welding; for the nut connection, as the nut at each position of the knob is required to ensure that each connection position is hermetically connected, the workload is large, and the installation efficiency is low; for welding, when welding is carried out on an installation site, the welding quality and the welding efficiency are affected due to the fact that the welding is difficult to align accurately.
Therefore, the patent with the publication number of CN207394164U discloses a connector and a connecting pipe used in cooperation with the connector, wherein an annular insertion groove is arranged at the end of a connector body, and the connecting pipe is directly inserted into the annular insertion groove, so that the connector and the connecting pipe can be quickly inserted and aligned; through set up elastic seal ring in the tip of connector, but make between connecting pipe and the connector disect insertion connect, connect efficiently, and can guarantee sufficient leakproofness simultaneously. Although the connection efficiency is improved to a certain extent, one end of the connector and one end of the welding pipe still need to be welded, for urban main water supply pipelines, the diameter of the pipeline is generally 300 mm-600 mm, the field welding still takes much time, the installation efficiency is reduced, and after the pipeline is buried, along with geological settlement, if the welding quality is not good, the pipeline is easy to crack and leak water at the welding position due to settlement extrusion; meanwhile, although the elastic sealing washer is arranged at one end of the connector, which is directly spliced with the connecting pipe, the deformation resistance of the elastic sealing washer is poor, and once the connector and the connecting pipe deviate, water leakage is easily caused; meanwhile, in order to facilitate the laying of on-site welding construction and accurate alignment, one end of the connecting pipe is inserted into the connector, the welding difficulty is increased by the mode, the welding rod must stretch into the gap between the connecting pipe and the connector in order to guarantee the sealing performance, the space of the gap is very limited, the operation difficulty is increased, and the construction efficiency is influenced.
