Collar type fluid flow divider

Technical Field

[0001] The present invention relates to the field of fluid connections, and in particular to a connection device for distributing fluid from a main line to a branch line.

Background

[0002] The gas and liquid conveying pipeline is widely applied to the industrial fields of petroleum, chemical industry and the like. In production application, a plurality of branch pipelines are often required to be connected with fluid in a main pipeline or a container for distributing the fluid, so as to meet industrial requirements and achieve the purposes of sample detection, fluid performance index testing, circulating heat dissipation and the like. The air source distributor is widely applied in the industrial field, and Chinese patent CN102788246A discloses an air source distributor which is an intermediate bridge formed by connecting a starting instrument and an air main pipe which are installed in a centralized manner and can conveniently control the on-off of each pipeline. Chinese patent CN104180115A discloses that the connection mode of the prior patent can cause the wall of the container to be too thick, which results in the whole device being heavy, so that the thin-wall type fluid flow divider is invented. The fluid shunt disclosed by the Chinese patent CN104180115A is thin in container wall and light in weight, but the processing and manufacturing process is not good enough, in the device, inserting of the fixing pin inch must be carried out from one end inside the container, after inserting is finished, welding of the end cover of the container is carried out, the assembling process is slow in assembling speed, and finally, the welding is easy to destroy to cause sealing failure, and the yield is low.

[0005] Further, the fastener thin-wall portion has a wall thickness less than a wall thickness of the female portion.

[0006] Further, the outer diameter of the thin wall portion is the same as that of the female screw portion, and the diameter of the central hole before the thin wall portion is plastically deformed is larger than that of the female screw portion. With this structure, the thin wall portion is more likely to bulge radially outward to form a protrusion portion without collapsing radially inward and obstructing the central hole as a flow passage when the flow path is deformed.

[0007] Furthermore, in order to facilitate the insertion of the plug-in body and the assembly of the round hole, the front end of the female thread part is in a furled shape.

[0008] Furthermore, in order to improve the friction force between the buckling piece and the inner wall of the container and prevent the buckling piece from loosening axially, the outer wall of the thin wall part is provided with grains or bulges so as to increase the friction force between the protrusion part and the inner part of the container.

[0009] Furthermore, in order to improve the friction force between the buckling piece and the inserting body and prevent the inserting body and the buckling piece from being loosened axially, the lower edge of the outer edge part is provided with grains or bulges, and the annular platform is also provided with the grains or the bulges.
