AI Technical Summary

Technical Problem

The existing dual fuel tank connecting pipeline design for special vehicles is complex, with strict welding quality requirements. It is prone to issues such as height and angle not meeting technical requirements, poor sealing effect, and assembly errors, which affect fuel supply and connection functions.

Method used

The system adopts a structure consisting of a shut-off valve, pipe fitting, hose, and bracket. The bracket is connected to the pipe fitting, and the bracket has a pre-set installation position, reducing on-site welding. The hose is fixed with clamps to ensure that the pipe fitting is in the preset position, meeting the height and angle requirements, reducing assembly difficulty and improving the sealing effect.

Benefits of technology

It simplifies the assembly process, improves installation efficiency and sealing effect, reduces costs, and ensures the installation accuracy and stability of connecting pipelines.

Abstract

The utility model discloses a kind of special vehicle double fuel tank intercommunication pipeline, it is related to special vehicle technical field, including cut-off valve, pipe joint, hose and support, pipe joint is equipped with two, two pipe joints are respectively connected with the two ends of cut-off valve, hose is equipped with two, two hoses are respectively connected with two pipe joints, the end of two hoses, far from pipe joint, is used to and the two oil tanks of special vehicle double fuel tank respectively intercommunication, support is connected with pipe joint, support is used to and special vehicle connection to make pipe joint be in preset position. By support, pipe joint is in preset position, so that the installation height and installation angle of intercommunication pipeline meet technical requirements;On the other hand, the intercommunication pipeline of the present application does not carry out field welding any more, and the number of parts is also reduced, the difficulty of part assembly is reduced, the sealing effect of intercommunication pipeline is guaranteed, the installation efficiency of intercommunication pipeline in special vehicle double fuel tank is improved, and the cost of intercommunication pipeline is reduced.
