Fluid and gas supply system
TLDR
In this article, a fluid or gas delivery system consisting of single or double control valves for regulating flow of a first fluid and a second fluid from corresponding first and second fluid sources into a mixing port is provided.Abstract:
A fluid or gas delivery system is provided for controlling fluid or gas temperature, flow rate and volume at a system outlet. The system comprises single or double control valves for regulating flow of a first fluid or gas and a second fluid or gas from corresponding first and second fluid or gas sources into a mixing port, wherein the first fluid or gas has a different temperature from the second fluid or gas. A fluid or gas supply control valve actuator operatively connected to the first and second fluid or gas supply valves actuate opening and closure operations of the valves. A thermosensor thermally coupled with the mixing port senses an estimated present temperature of a mixed fluid or gas within the mixing port. A flow control valve regulates flow of a mixed fluid or gas at the system outlet. A flow control valve actuator operatively connected to the flow control valve actuates opening and closure thereof. A user interface including user input means for selecting a set temperature, flow rate and volume of fluid or gas at the system outlet is provided along with a user display for displaying one or more system functions or parameters. Control means are provided for receiving signals from the thermosensor and user interface and for processing the signals to generate appropriate control signals to control the fluid or gas supply control valve actuator and flow control valve actuator means to achieve programmed or user-selected set temperature, flow rate and volume at the system outlet.read more
