Title
(EN) VALVE ASSEMBLY FOR AGRICULTURAL SPRAYING, RELATED APPARATUS, RELATED SYSTEMS, AND RELATED METHODS
(FR) ENSEMBLE SOUPAPE POUR PULVÉRISATION AGRICOLE, APPAREIL ASSOCIÉ, SYSTÈMES ASSOCIÉS ET MÉTHODES ASSOCIÉES
Abstract
(EN) Valve assembly for agricultural spraying, related apparatus, related systems, and related methods. In accordance with an example, a valve assembly for agricultural spraying, the valve assembly includes a top valve, a bottom valve, and a fluid conduit. The top valve includes an air inlet, an air outlet, a top liquid inlet, and a top liquid outlet. The top valve provides fluid communication therethrough in at least two states. The bottom valve includes a bottom liquid inlet, a bottom liquid outlet, a discharge outlet, and a drain outlet. The bottom valve provides fluid communication therethrough in at least three states. The fluid conduit in fluid communication with the top liquid outlet and the bottom liquid inlet. The top valve and the bottom valve are in fluid communication via the fluid conduit. When the top valve is in the first state, the bottom valve is in the second state.
(FR) L'invention concerne un ensemble soupape pour pulvérisation agricole, un appareil associé, des systèmes associés et des méthodes associées. Selon un exemple, l'invention concerne un ensemble soupape pour pulvérisation agricole, l'ensemble soupape comprend une soupape supérieure, une soupape inférieure et un conduit de fluide. La soupape supérieure comprend une entrée d'air, une sortie d'air, une entrée de liquide supérieure et une sortie de liquide supérieure. La soupape supérieure assure une communication fluidique à travers celle-ci dans au moins deux états. La soupape inférieure comprend une entrée de liquide inférieure, une sortie de liquide inférieure, une sortie de décharge et une sortie de drain. La soupape inférieure assure une communication fluidique à travers celle-ci dans au moins trois états. Le conduit de fluide est en communication fluidique avec la sortie de liquide supérieure et l'entrée de liquide inférieure. La soupape supérieure et la soupape inférieure sont en communication fluidique par l'intermédiaire du conduit de fluide. Lorsque la soupape supérieure est dans le premier état, la soupape inférieure est dans le deuxième état.
