Abstract
Embodiments of the present invention provide components and a system for providing a safer environment for using a cutting torch. The system includes a cutting torch and a control box. There is communication from the user to the control box to allow fluids to flow to the torch. The control box includes closed biased valve(s) such that if there is a condition where there is no instruction from the torch to the control box and/or power is lost, the valves will shut, preventing fluid from flowing into the torch.
Claims20
An apparatus comprising:
- a cutting torch comprising:
- a safety actuator comprising a trigger;
- two torch inlets, comprising a first torch inlet and a second torch inlet;
- a secondary oxygen valve;
- a torch outlet;
- and
- a conduit;
- wherein the two torch inlets are configured to allow liquids, gasses, or a combination thereof into the cutting torch;
- the torch outlet is configured to allow the liquid, gas, or the combination of the two exit the torch outlet;
- the secondary oxygen valve is located in a path from the first torch inlet and the torch outlet, and the secondary oxygen valve is configured to increase the flow, along the path to the torch outlet, when actuated;
- and the safety actuator is in communication with the conduit, and the safety actuator is configured to express a state of the trigger along the conduit.
An apparatus comprising:
- a control box comprising:
- a housing;
- a fuel valve, wherein the fuel valve is closed biased;
- an oxygen valve, wherein the oxygen valve is closed biased;
- a fuel inlet;
- an oxygen inlet;
- a fuel outlet;
- and
- an oxygen outlet;
- wherein the fuel valve is located in the housing and is configured to control flow between the fuel inlet and the fuel outlet;
- the oxygen valve is located in the housing and is configured to control flow between the oxygen inlet and the oxygen outlet;
- and only material that has flowed through the oxygen valve can flow out the oxygen outlet.
An apparatus comprising:
- a cutting torch comprising:
- a safety actuator comprising a trigger;
- two torch inlets, comprising a first torch inlet and a second torch inlet;
- a secondary oxygen valve;
- a torch outlet;
- and
- a conduit;
- and
- a control box comprising:
- a housing;
- a fuel valve, wherein the fuel valve is closed biased;
- a fuel inlet;
- and
- a fuel outlet;
- wherein the cutting torch is in communication with the control box via the conduit;
- one of the two torch inlets is connected to the fuel outlet via a line;
- the two torch inlets are configured to allow liquids, gasses, or a combination thereof into the cutting torch;
- the torch outlet is configured to allow the liquid, gas, or the combination of the two exit the torch outlet;
- the secondary oxygen valve is located in a path from the first torch inlet and the torch outlet, and the secondary oxygen valve is configured to increase the flow, along the path to the torch outlet, when actuated;
- the safety actuator is in communication with the conduit, and the safety actuator is configured to express a state of the trigger along the conduit to the fuel valve, and the fuel valve will open when the trigger is actuated;
- and the fuel valve is located in the housing and is configured to regulate flow between the fuel inlet and the fuel outlet.
