Fluid application system

摘要

A fluid application system includes a diluent reservoir, a chemical container, a sprayer housing, a manifold located in the sprayer housing, and a pump assembly in fluid communication with an outlet of the manifold. The manifold includes a diluent inlet in fluid communication with the diluent reservoir, a chemical inlet in fluid communication with the container, a mixing chamber in fluid communication with the diluent inlet and the chemical inlet and the outlet of the manifold. The pump assembly draws a mixture of the chemical and the diluent from the manifold and sprays the mixture of the chemical and the diluent from the nozzle.

1. A fluid application system for mixing a chemical with a diluent and spraying a mixture of the chemical and the diluent, the system comprising:
a sprayer housing; a diluent reservoir for holding the diluent; a chemical container for containing the chemical, the chemical container including a chemical dip tube for delivering chemical to a valve in an opening of the chemical container, the chemical dip tube being in fluid communication with a restriction orifice at an entry port of a valve body of the valve having a smaller inner diameter than an inner diameter of an adjacent section of the chemical dip tube wherein the valve has a closed position in which fluid flow is blocked from the opening of the container and the valve has an open position in which fluid can flow from the opening of the container, the valve being moved from the closed position to the open position when the chemical container is attached to the sprayer housing; a manifold located in the sprayer housing, the manifold including a diluent inlet in fluid communication with the diluent reservoir and a mixing chamber of the manifold, the manifold including a chemical inlet in fluid communication with the chemical dip tube and the mixing chamber, the manifold including an outlet in fluid communication with the mixing chamber; and a pump assembly including a pump chamber in fluid communication with the outlet of the manifold, the pump assembly drawing a mixture of the diluent and the chemical into the pump assembly from the outlet of the manifold and then expelling the mixture of the diluent and chemical from a nozzle for spraying the mixture of the chemical and the diluent.
