Sealing ring water cooling device of vacuum reflow soldering furnace

The invention discloses a water cooling device for a sealing ring of a vacuum reflow soldering furnace, the vacuum reflow soldering furnace is provided with a vacuum cavity, and a cavity runner wrapping the sealing ring is arranged in the vacuum cavity. The sealing ring water cooling device of the vacuum reflow soldering furnace has the beneficial effects that a traditional stainless steel clamping sleeve connector is not used, the plane sealing mode that the gland plate presses and fixes the connector sealing ring is adopted, the reliability of connection between a pipeline and a cavity can be guaranteed, the connector is not prone to water leakage, and the sealing effect is good. Meanwhile, the steam separator and the condenser are used for quickly liquefying steam in the pipeline in time, the impact of the steam on the pipeline system is reduced, cooling water is recycled and recycled, in addition, the pipeline system is additionally provided with a one-way valve and an automatic drainer, and the separator
