Water flow controlling device for pistol nozzle, has flowmeter measuring quantity of water circulating in duct, and valve interrupting circulation of water flow inside device, when measured water quantity is higher than threshold value

摘要

#CMT# #/CMT# The device has a transmission duct (20) for transmitting a flow of water between an inlet end (21) connected to a watering hose (5) and an evacuation nozzle type outlet end (10). A flowmeter (9) measures the quantity of water circulating in the duct. A diaphragm valve (18) interrupts the circulation of the water flow inside the device, when the measured water quantity is higher than a threshold value. #CMT#USE : #/CMT# Device for controlling the flow of water traversing a watering hose connected to a pistol nozzle (claimed) that is utilized for watering a plant in a garden. Can also be used for watering paint, plaster, cement or coating. #CMT#ADVANTAGE : #/CMT# The device allows a user to have the knowledge, in real time, about water consumption, and to program the threshold values for preventing the wastage of water, thus efficiently and automatically reducing the water consumption to save money on water bill. The device ensures improved life duration during the utilization of the watering hose. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a pistol nozzle. 1 : Pistol nozzle 5 : Watering hose 9 : Flowmeter 10 : Evacuation nozzle type outlet end 18 : Diaphragm valve 20 : Transmission duct 21 : Inlet end.
