Lubrication System for a Gate Valve

摘要

A lubrication system for a gate valve having a moveable gate and a gate sealing element located between first and second housing sections. The lubrication system includes a cartridge having a lubricant for lubricating the gate sealing element. The lubrication system also includes a plunger element for moving the lubricant from the cartridge to the gate sealing element. In addition, the lubrication system includes a lubricant passageway located between the plunger element and the gate sealing element for supplying the lubricant moved by the plunger element to the gate sealing element. Further, the lubrication system includes a plunger contact member attached to the gate by an attachment element wherein the plunger contact element engages the plunger element. Energizing an actuator causes movement of the gate and corresponding movement of the plunger element to cause the lubricant to move from the cartridge to the gate sealing element.
