Description

Ferrule fluid diverting device

Technical field

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

Background technique

[0002] Gas and liquid conveying pipelines are widely used in petroleum, chemical and other industrial fields. In production applications, the fluid in the main pipe or vessel often needs to be connected to multiple branch lines to distribute fluids to meet industrial needs, to achieve sample testing, fluid performance testing, and heat dissipation. The gas source distributor is the most widely used in the industrial field. Chinese patent CN102788246A discloses a gas source distributor, which is a centrally connected starting instrument connected to the gas main pipe, which can be conveniently controlled. The continuity of each pipeline. The Chinese patent CN104180115A considers that the connection method of the prior patent causes the container wall to be too thick, which causes the entire device to be cumbersome, and thus an improvement has been made to invent a thin-wall type fluid splitter. The fluid shunt disclosed in Chinese Patent No. CN104180115A has a thin wall and a light weight, but the manufacturing process is poor. In this device, the insertion pin must be carried out from the inner end of the container, and after the insertion is completed, the container is further processed. The welding of the end caps, the assembly process, the assembly speed is slow, and finally the welding is easily broken, resulting in seal failure and low yield.

technical problem

[0003] The object of the present invention is to overcome the deficiencies of the prior art described above, and to provide a ferrule type fluid diverting device which can achieve a firm connection and a stable seal by using a thin-walled container and a snap-fit connection. Fast processing.
