Abstract
A water controlling kit is connected to the fluid system, of a fire truck for example, used for pumping water to one or more fire hoses. The kit has a water level gauge, a signaling element and a control valve and is adapted to maintain the pressure at the inlet of the pump of the fire truck within a preselected range of about 1.5 to about 3 psi. during discharge from the pump and pressure fluctuations of the pressurized water supply supplying water to the fire truck reservoir.
Claims8
In the fluid system of a fire truck used for pumping water to one or more fire hoses, said fluid system having a water reservoir connected in fluid communication with a pump, a discharge manifold, and a pressurized water inlet that is connectable to a pressurized water supply source, the improvement comprising:
- a water controlling kit having a water level gauge, a signaling element, and a control valve;
- said water level gauge having preselected first and second set points and being connectable in fluid communication with the water reservoir;
- said signaling element being connectable to the water level gauge and being adapted to deliver a first signal in response to the water level being at the first set point and a second signal in response to the water level being at the second set point;
- and
- said control valve being connectable in communication with the fluid reservoir, the signaling element, and the pressurized water inlet and being adapted to control the water level in the water reservoir and resultingly the water pressure at an inlet of the pump in response to receiving said first and second signals.
In the fluid system of a fire truck used for pumping water to one or more fire hoses, said fluid system having a water reservoir connected in fluid communication with a pump, a discharge manifold , and a pressurized water inlet that is connectable to a pressurized water supply source, the improvement comprising:
- a water controlling kit having a water level gauge, a controlling-signaling element, and a control valve;
- said water level gauge having a multiplicity of set points and being connectable in fluid communication with the water reservoir;
- said controlling-signaling element being connectable to the water level gauge and being adapted to receive signals from the set points, determine rates of change of the water level in the water reservoir, and responsively deliver controlling signals;
- and
- said control valve being connectable in communication with the fluid reservoir, the controlling-signaling element, and the pressurized water inlet and being adapted to operate the control valve and maintain the water level in the water reservoir substantially constant in response to receiving said controlling signals.
