Abstract
A sprayer system includes a pair of tanks, one for storing a dilutent and another for storing a chemical to be mixed with the dilutent in a selected concentration based on the selected orifice of a valve sprayed on the surface. Mixing of chemical with dilutent occurs on the suction side of a diaphragm pump which delivers the mixture to one or more nozzles. Should flow between either tank and the pump be interrupted, flow to the nozzles is automatically interrupted.
Claims16
A chemical sprayer comprising:
- (a) a first tank holding a chemical concentrate;
- (b) a valve regulating the flow of chemical concentrate from the first tank, the valve comprises a first plate and a second plate in face-to-face registration with each other and rotatable with respect to each other to different positions, the first plate having a first orifice and the second plate having a plurality of orifices of different sizes such that any of the second orifices can be selectively aligned with the first orifice to control flow rate of chemical from the first tank through the valve;
- (c) a second tank holding a dilutent;
- (d) a diaphragm pump having a suction port and a pressure port;
- (e) a mixing connector operatively coupled to the suction port of the pump, the first tank via the valve and the second tank such that the chemical concentrate and dilutent are mixed at a predetermined ratio before reaching the pump;
- and
- (f) a spray nozzle operatively connected to the pressure port of the pump;
- wherein flow to the nozzle stops when flow from either the first tank or the second tank to the mixing connector is interrupted.
