Description

Technical Field

[0001] The utility model belongs to the technical field of lubricating oil distribution valves, in particular to a multi-position lubricating oil distribution valve. Background Art

[0002] Lubricant distribution is a crucial process in the lubrication system, which aims to ensure that each lubrication point can get the right amount of lubricant to maintain the stable operation of the equipment and extend its service life. The lubricant distributor is the key equipment to achieve this process. The basic working principle of the lubricant distributor is to transport the lubricant from the oil tank to the distributor through a pipeline, and then the distributor distributes the lubricant to each lubrication point according to the set ratio. This distribution process is completed by multiple components, including pressure controller, distributor, lubrication pipeline and electrical control system. The pressure controller is responsible for controlling the flow and pressure of the lubricant to ensure that the lubricant can be distributed to each lubrication point according to the set ratio. The distributor usually consists of multiple distribution heads, each of which can distribute the lubricant to a lubrication point. The lubrication pipeline is a bridge connecting the distributor and the lubrication point to ensure the smooth flow of the lubricant. The electrical control system controls and monitors the entire system to ensure the stable operation of the system.

[0003] At present, the lubricating oil distribution valve is relatively simple. During its use, its distribution ability is poor. During its overall distribution period, it is unable to realize any combination of flow and cut-off states between multiple output channels. When the lubricating oil distribution valve cannot realize any combination of flow and cut-off states between multiple output channels, it may lead to defects such as uneven lubrication, restricted operation, low energy efficiency, difficult maintenance and reduced system reliability.
