Rinse valve for vacuum waste system

摘要

The apparatus and method of the invention provides for a rinse valve for controlling the flow of rinse fluid to a vacuum waste receptacle. The rinse valve comprises a primary rinse fluid flow path and a poppet assembly intersecting the primary rinse fluid flow path. The rinse valve also comprises a solenoid-driven fluid control device having a solenoid armature movable between an inactive state in which the armature engages the poppet assembly to block flow of the rinse fluid through a poppet channel and an active state in which the solenoid armature is disengaged from the poppet assembly to allow flow of the rinse fluid through the poppet channel to raise the poppet assembly, permitting the flow of the rinse fluid through the primary rinse fluid flow path and out of the valve, the armature being located at all times out of the primary flow path of the rinse fluid.

主权项

1. A rinse valve for controlling the flow of rinse fluid to a vacuum waste receptacle comprising:
a valve block having an inlet cavity that receives rinse fluid and an outlet that supplies rinse fluid from the rinse valve to the waste receptacle; a primary rinse fluid flow path from the inlet cavity that receives rinse fluid to the outlet that supplies rinse fluid from the rinse valve to the waste receptacle; an inlet venting assembly disposed in the valve block proximal and connected to the inlet opposite the inlet cavity for venting air that enters the inlet cavity with the rinse fluid; a vacuum breaker outlet assembly,
wherein the inlet venting assembly includes a first sleeve valve and the vacuum breaker outlet assembly includes a second sleeve valve,wherein the first sleeve valve includes a first sleeve and a first sleeve supporting member, the first sleeve supporting member slidably receiving the first sleeve, the first sleeve supporting member having a vent opening in communication with the atmosphere outside of the rinse valve; a poppet assembly intersecting the primary rinse fluid flow path, the poppet assembly including a poppet channel that drains a pilot chamber to facilitate opening of the poppet assembly to permit the flow of rinse fluid through the primary rinse fluid flow path; a secondary rinse fluid flow path branching off of the primary rinse fluid flow path and leading to the poppet channel; and a solenoid-driven fluid control device having a solenoid armature movable between an inactive state in which the armature engages the poppet assembly to block flow of the rinse fluid through the poppet channel and an active state in which the solenoid armature is disengaged from the poppet assembly to facilitate rinse fluid entering the poppet channel to raise the poppet assembly, permitting the flow of the rinse fluid through the primary rinse fluid flow path and out of the valve, the armature being located at all times out of the primary rinse fluid flow path.
