Abstract

A gas pipe terminal assembly for minimization of fire hazards associated with conductance of a flammable substance. The system includes a pipe having a flange at each end. Each flange includes at least one check valve and a flame screen mounted in the interior of the flange to control a gas flow through the flange. The flange includes wire guide holes and set screw holes within the outside diameter of the pipe, and at least one wire segment in tension inside the pipe and connected to at least one fusible link. At least one fusible link is configured to fuse upon exposure to a temperature above 100° C. and thereby release the tension and activate at least one fire suppression device.

First claim

1 . A gas pipe terminal assembly for minimization of fire hazards associated with conductance of a flammable substance, comprising:
a pipe having a flange at each end; said flange having at least one of a check valve and a flame screen mounted in an interior of the flange to control a gas flow therethrough; said flange having wire guide holes and set screw holes within an outside diameter of the pipe; at least one wire segment in tension inside said pipe and connected to at least one fusible link; and said at least one fusible link configured to fuse upon exposure to a temperature above 100° C. and thereby release said tension and activate at least one fire suppression device.

2 . The apparatus of claim 1 , further comprising:
said at least one fusible link located inside said pipe, wherein the fusing of the fusible link activates said check valve as said fire suppression device.

3 . The apparatus of claim 1 , further comprising:
a fire extinguisher connected to the inside of said pipe; and said at least one fusible link located inside said pipe, wherein the fusing of the fusible link activates the fire extinguisher as the fire suppression device.

4 . The apparatus of claim 3 , further comprising:
said at least one fusible link located inside said pipe, wherein the fusing of the fusible link activates at least one of said check valve and said fire extinguisher.

5 . The apparatus of claim 4 , wherein the at least one fusible link comprises plural fusible links and the fusible links have equal melting temperatures.

6 . The apparatus of claim 4 , wherein the at least one fusible link comprises plural fusible links and the fusible links have different melting temperatures.

7 . The apparatus of claim 1 , further comprising:
at least one fusible link located inside said pipe, wherein the fusing of the fusible link activates at least one of said check valve and a fire extinguisher disposed outside the pipe.

8 . The apparatus of claim 1 , further comprising:
wire clamps securing the wire segments to each other, and set screws securing the wire segments to at least one of the flanges.

9 . The apparatus of claim 1 , further comprising:
wire guide caps sealing the wire guide holes or sealing wire segments passing therethrough.

10 . The apparatus of claim 1 , wherein the fusible link comprises at least one of brass, bronze, and stainless steel alloys.

11 . A system for suppression of fire hazards associated with conductance of a flammable substance, comprising:
terminal assembly comprising the gas pipe terminal assembly of claim 1 ; a hose assembly connected to said first terminal assembly; a second terminal assembly connected to said hose assembly; and a fire extinguisher disposed in a vicinity of at least one of the first terminal assembly, the hose assembly, and the second terminal assembly.

12 . The system of claim 11 , further comprising:
said at least one fusible link located outside said hose assembly, wherein the fusing of the fusible link activates said check valve.

13 . The system of claim 11 , further comprising:
said at least one fusible link located outside said hose assembly, wherein the fusing of the fusible link activates said fire extinguisher.

14 . The system of claim 11 , further comprising:
a supplemental check valve disposed inside of at least one of the hose assembly and the second terminal assembly.

15 . The system of claim 14 , further comprising:
said at least one fusible link located outside said hose assembly, wherein the fusing of the fusible link activates said supplemental check valve.

16 . The system of claim 11 , further comprising:
at least one of a check valve disposed inside at least one of the first terminal assembly, the hose assembly, and the second terminal assembly.

17 . The system of claim 11 , wherein said hose assembly is disposed inside of a gas appliance.

18 . The system of claim 11 , wherein said hose assembly is providing a flammable substance to a gas appliance.

19 . The system of claim 11 , further comprising:
a computer processor for monitoring the operating status of the at least one fire extinguisher.

20 . The system of claim 19 , wherein the computer processor is programmed to at least one of alert emergency response personnel of fire, activate fire alarms, activate sprinklers, provide mobile alerts to designated parties if the status of said fire extinguisher changes to release fire suppressant, and provide said mobile alerts to said designated parties if the status of said check valve changes.
