Description

Technical Field

[0001] This utility model relates to the field of refueling technology for mining loaders, specifically a control valve assembly for a transfer machine that is easy to operate. Background Technology

[0002] Mining loaders are mechanical equipment mainly used for the collection, transportation, and loading of crushed stone and soil materials in various mines, hydropower projects, and tunnels, such as phosphate mines, iron mines, copper mines, gold mines, silver mines, lead-zinc mines, and coal mines, where the space is confined. However, traditional loaders have their diesel tanks and high-pressure oil pumps directly connected through oil pipelines. This setup leads to fuel waste during refueling and increases operating costs.

[0003] According to a public notice (Announcement No.: CN214366474U) of a fuel-saving control valve device for a mining loader, the above application includes a device body, which includes a fuel-saving pipe. An oil pipe is fixedly connected inside the fuel-saving pipe, and a flow pipe is movably connected inside the oil pipe. Several flow holes are evenly opened on the flow pipe. A closing plate is installed inside the flow pipe. An inner connecting rod is fixedly connected to the upper side of the closing plate. A closing plug is installed on the upper side of the flow pipe. The inner connecting rod passes through the flow pipe and is fixedly connected to the closing plug. A connecting rod is fixedly connected to the upper side of the closing plug.

[0004] However, in actual use, when stopping fuel refueling, the connecting rod needs to be manually rotated to gradually reduce the flow rate of the orifice before closing it. The closing process is a gradual adjustment process and cannot achieve instantaneous flow interruption. When it is necessary to quickly stop fuel refueling, there may be a delay, resulting in unnecessary fuel leakage. In view of this, we propose a control valve assembly for transfer machines that is easy to operate. Utility Model Content
