Abstract
A liquid dispensing valve for dispensing of liquid solution, the liquid dispensing valve operable to create a vacuum buildup of pressure, such that the liquid moves on a recirculation path from the intake port to the output port. The recirculation of the liquid prevents sediment within the liquid from settling, and further prevents backpressure, and allows for continuous recirculation of the solution through a suction return line, providing generally consistent flow of liquid. The liquid dispensing valve's ability to minimize sediment buildup allows for a quick cleaning of the lines while also minimizing potential contamination of the general area.
Claims20
A liquid dispensing valve, said liquid dispensing valve comprising:
- a casing having an intake port formed on a first side of said casing and an output port formed on a second side of said casing;
- a tubular main liquid passage extending along an axis extending from the intake port to the output port wherein the tubular main liquid passage further comprises a hourglass-shaped section located between the intake port and output port, the hourglass-shaped section comprised of a reduced diameter nozzle and an extending diameter nozzle;
- a suction port formed on a side of said casing, said suction port located perpendicular to the hourglass-shaped section of the tubular main liquid passage, further comprising a tubular suction liquid passage extending along an axis from the suction port to the hourglass-shaped section of the main liquid passage;
- a tubular recirculation liquid passage disposed in a first position on the tubular main liquid passage, and further disposed in a second position on the tubular main liquid passage sandwiching the hourglass-shaped section of the tubular main liquid passage;
- and
- a bypass valve port formed on a side of said casing located opposite of the suction port, the bypass valve port extending perpendicularly from the tubular recirculation liquid passage.
A liquid solution dispensing system for recirculating and dispensing of liquid, said liquid solution dispensing system comprising:
- a heavy machine having a liquid solution tank;
- an intake hose having a first and second distal end, said intake hose removably connected to the liquid solution tank at the first distal end of the intake hose;
- a liquid dispensing valve including a casing having an intake port and an output port, the intake port of the liquid dispensing valve removably connected to the second distal end of the intake hose, the liquid dispensing valve comprising:
- a tubular main liquid passage extending along an axis extending from the intake port to the output port;
- a hourglass-shaped section located within the tubular main liquid passage;
- a suction port located perpendicular to the hourglass-shaped section, wherein a tubular suction liquid passage extends along an axis from the suction port to the main liquid passage, the suction port additionally comprising a connecting valve;
- a tubular recirculation liquid passage disposed in a first position on the tubular main liquid passage extending to a second position on the tubular main liquid passage;
- a bypass valve port formed on a side of the casing, the bypass valve port extending perpendicularly from the tubular recirculation liquid passage;
- a spring-loaded relief valve positioned in the bypass valve port;
- a feed hose having a first and second distal end, the feed hose first distal end removably connected to the output port of the liquid dispensing valve;
- a sprayer feed line, removably connected to the second distal end of the feed hose;
- a plurality of sprayer tips connected to the sprayer feed line;
- and
- a return hose having a first and second distal end, the first distal end of the return hose removably connected to the sprayer feed line, and the second distal end removably connected to the connecting valve of the suction port of the liquid dispensing valve.
