연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

A heating system can include certain pressure sensitive features. These features can be configured to change from a first position to a second position based on a pressure of a fuel flowing into the feature. These features can include, fuel selector valves, pressure regulators, burner nozzles, and oxygen depletion sensor nozzles, among other features.

1. A heating system for use with either a first fuel or a second fuel different from the first, the heating system comprising: a fuel selector valve comprising: a housing having an input, a first output, and a second output;a first valve in-between the input and the first output, the first valve comprising a first valve body and a first valve seat, the first valve configured to have a closed position wherein the first valve body is engaged with the first valve seat and an open position wherein the first valve body is disengaged from the first valve seat;a second valve in-between the input and the second output, the second valve comprising a second valve body, and a second valve seat, the second valve configured to have a first closed position wherein the second valve body is engaged with the second valve seat and an open position wherein the second valve body is disengaged from the second valve seat;wherein the fuel selector valve is configured such that the first valve and the second valve are configured to move between their respective open and closed position based on a predetermined fluid pressure acting on the valve and the pressure of the fluid entering the input of the fuel selector valve determines whether either the first valve or the second valve is open;a first fuel pressure regulator downstream from the fuel selector valve and in communication with the first output, the first fuel pressure regulator configured to control the flow of fluid within a first predetermined pressure range; anda second fuel pressure regulator downstream from the fuel selector valve and in communication with the second output, the second fuel pressure regulator configured to control the flow of fluid within a second predetermined pressure range, different from the first. 2. The heating system of claim 1, wherein the fuel selector valve further comprises first and second biasing members, the first biasing member configured to at least partially control the opening and closing of the first valve and the second biasing member configured to at least partially control the opening and closing of the second valve. 3. The heating system of claim 1, wherein the second valve further comprises a third valve seat, and the second valve is further configured to have two closed positions wherein in the second closed position the second valve body is engaged with the third valve seat. 4. The heating system of claim 3, wherein the second valve is configured such that 1) in an initial position with no fluid pressure acting on the second valve, the second valve is in the first closed position, 2) at a first set pressure acting on the second valve, it is in the open position, and 3) at a second set pressure acting on the second valve, it is in the second closed position. 5. The heating system of claim 1, wherein the first and second valve seats are adjustable and are configured to be able to calibrate the first and second valves to open and/or close at particular pressures. 6. The heating system of claim 1, wherein at least one of the first and second valve seats are adjustable from outside of the housing to be able to calibrate the first valve or the second valve. 7. The heating system of claim 2, wherein each of the first and second biasing members comprise at least one of a spring and a diaphragm. 8. The heating system of claim 1, wherein at least one of the first and second valves comprises a passageway having an inlet at a top of the valve and at least one outlet at the side of the valve configured such that the flow of fluid is directed through the passageway and the fluid pressure acts on an internal wall of the valve within the passageway. 9. The heating system of claim 1, wherein the heating system is part of a water heater, a fireplace, an oven, a stove, a BBQ, or a dryer. 10. The heating system of claim 1, further comprising a gas valve; a burner nozzle; and a burner. 11. A heating system for use with either a first fuel or a second fuel different from the first, the heating system comprising: a fuel selector valve comprising: a housing having an inlet, an output, a first flow path therethrough and a second flow path therethrough different from the first flow path;at least one pressure sensitive gate within the housing, wherein the at least one pressure sensitive gate is configured to be open when a fluid within a first pressure range is flowing through the fuel selector valve and closed when a fluid within a second pressure range, different from the first, is flowing through the fuel selector valve, wherein the flow of fluid acts on the gate to either open or close the gate;wherein the fuel selector valve is configured such that when the gate is open, fluid flows through the first flow path and when the gate is closed, fluid flows through the second flow path;a first fuel pressure regulator downstream from the fuel selector valve and in communication with the output, the first fuel pressure regulator configured to control the flow of fluid within a first predetermined pressure range;a second fuel pressure regulator downstream from the fuel selector valve and in communication with a second output, the second fuel pressure regulator configured to control the flow of fluid within a second predetermined pressure range, different from the first;a burner nozzle; anda burner. 12.
