Reversing valve group of pipe jacking machine

Abstract

The invention discloses a reversing valve group of a pipe jacking machine, which can solve the technical problems that the existing pipe jacking machine is complicated in operation, used hydraulic elements are common and cannot be suitable for the action control of various types of pipe jacking machines, the efficiency in work is not high, and the stability performance needs to be improved. The reversing valve group of the pipe jacking machine comprises a reversing valve plate, connector bodies, electromagnetic reversing valves, stacked hydraulic control one-way valves and stacked overflow valves; pressure measurement connectors are mounted on the other side of the bottom end of the reversing valve plate; seven groups of electromagnetic reversing valves are mounted at the top of the reversing valve plate; the pressure measurement connectors are connected with the electromagnetic reversing valves; the stacked hydraulic control one-way valves are mounted between the top of one end of thereversing valve plate and the four groups of the electromagnetic reversing valves above; and the stacked overflow valves are mounted between the top of the other end of the reversing valve plate andthe electromagnetic reversing valves above. The reversing valve group of the pipe jacking machine is wide in application range, is convenient and quick to use and is high in operation precision, so that the stability performance of the pipe jacking machine is high in use.

Description

technical field [0001] The invention relates to a reversing valve group, in particular to a reversing valve group of a pipe jacking machine, which belongs to the technical field of pipe jacking machines. Background technique [0002] Pipe jacking machine is an important equipment for culvert and pipeline construction, mainly for drainage pipelines, south-to-north water diversion, gas and heating pipelines, transmission and exhaust pipelines, fire-fighting pipelines, communication pipelines, electric power, oil pipelines, pipelines crossing road and railway overpasses and riverbeds And culvert construction projects, and the mud-water balance pipe jacking machine 7-4WE6 reversing valve group is an important part of the pipe jacking machine, mainly to operate the various actions of the pipe jacking machine. At present, there is no reversing valve group specially for pipe jacking machines on the market. Therefore, a reversing valve group specially for the pipe jacking machine i...
