Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic pump stations, in particular to a hydraulic pump station valve component with a connection structure. Background Art

[0002] A hydraulic pump station is a hydraulic source device or a hydraulic device including a control valve, which is composed of a hydraulic pump, a driving motor, an oil tank, a directional valve, a throttle valve, a relief valve, a solenoid valve, etc. The valve components of a hydraulic pump station are an important part of the hydraulic system. They are responsible for controlling the flow direction, pressure and flow of the hydraulic oil to achieve precise motion control of mechanical equipment. A hydraulic pump station is usually composed of a pump device, an integrated block or a valve combination, an oil tank, an electrical box, etc.

[0003] In order to facilitate unified maintenance management, the valve components of a small hydraulic pump station are generally integrated with multiple throttle valves and relief valves. At the same time, it is necessary to cooperate with the pipeline design of the hydraulic pump station. The valve bodies are installed corresponding to their respective pipelines. The pump station is driven by force during operation, and the pipeline will vibrate slightly. The interval between the valve bodies is small. In order to avoid collision and friction with each other, a shell is set up to fix them. They are fixed to each other by bolts. This requires drilling suitable installation holes on the valve body shell, and sometimes on-site drilling and positioning installation is required, which is very troublesome. Utility Model Content
