AI Technical Summary
The existing valve lubrication requires manual replenishment at regular intervals, which increases the workload and makes it impossible to collect excess lubricating oil, resulting in waste.
A self-lubricating valve was designed, which divides the valve into upper and lower lubrication chambers by setting a partition inside the sealing sleeve. The partition is moved by the adjusting rod, so that the lubricating fluid flows between the chambers. Combined with a filter screen and a one-way valve, automatic lubrication is achieved and impurities are filtered out.
It achieves automatic lubrication of the valve during the opening and closing process, reduces wear on structures such as the regulating rod, improves efficiency, and reduces lubricant waste.
