External type converging valve for mobile hydraulic power station

Abstract

The invention discloses an external type converging valve for a mobile hydraulic power station. The external type converging valve comprises an oil inlet cover, a third seal ring and bearing plates. The upper end face and the lower end face of each movable valve are provided with a groove and through holes correspondingly. A bearing base is fixed to the upper side of a base through second bolts. The bearing plates are clamped and connected between the bearing base and the base. An oil storage groove is formed on the lower side of the bearing plates. A supporting column is fixed into the oil storage groove. An oil outlet channel is formed in the right side of the oil storage groove. An annular cooling groove is formed on the outer side of the oil outlet channel. According to the external type converging valve for the mobile hydraulic power station, the movable valves can move up and down under the action of hydraulic cylinders and hydraulic rods, the movable valves are in a switched-offstate when being clamped and connected to the bearing base, the movable valves are in a switched-on state when getting away from the bearing base to be completely located in openings, oil can flow toa corresponding first channel, a second channel or a third channel to converge, and the oil flowing and stopping operation is more convenient.

Description

technical field [0001] The invention relates to the related technical field of a mobile hydraulic power station, in particular to an external confluence valve for a mobile hydraulic power station. Background technique [0002] The hydraulic power station is generally an electromechanical device that provides lubrication and power for the operation of large and medium-sized industrial machinery. It supplies oil according to the flow direction, pressure and flow required by the driving device. It is suitable for various machines that separate the driving device from the hydraulic station. The station is connected to the driving device with oil pipes, and the hydraulic system can realize various prescribed actions. The mobile hydraulic power station, also known as the mobile pump truck or mobile pump station, replaces the original fixed pump station. It is convenient and fast, so it is widely used. When it is necessary to combine the oil in several pipelines, it is necessary to...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an external confluence valve for a mobile hydraulic power station to solve the problem that the existing confluence valve proposed in the above background technology is difficult to filter and separate impurities doped in the oil before confluence, thus affecting The quality of the oil, and the operation of controlling the opening and closing of the mobile valve is more troublesome. At the same time, the temperature of the oil after merging is very high and cannot be cooled in time, which will affect the subsequent use.
