VALVE WITH ECONOMY DEVICE AND GAS FLOW INTERRUPTION IN CASE OF FIRE ON THE HOSE

SOUPAPE COMPORTANT UN DISPOSITIF D'ECONOMIE, A INTERRUPTION D'ECOULEMENT DE GAZ EN CAS D'INCENDIE SUR LE TUYAU SOUPLE

English Abstract

A valve with economy device and gas flow interruption in case of fire on the hose comprising a metallic ring with a flow and economy device placed inside the end of the hose fixed by an aluminum ring with a flow-regulating valve and male bolt that attaches to a cylindrical tube with a female bolt and attached to a long burner with a hole for gas to flow. Inside the cylindrical tube there is a needle with a protuberance and hole and a seal ring on the conic needle with a hole and, over those, a pressure spring strained by a galvanized wire passing through the hole on the needle. On the upper end of the galvanized wire a pressure glove is attached to a nylon string that runs through the inside of the hose until the upper end.

French Abstract

L'invention concerne une soupape comportant un dispositif d'économie et présentant une interruption d'écoulement de gaz en cas d'incendie sur le tuyau souple, ladite soupape comportant une bague métallique, avec un dispositif d'écoulement et d'économie, placée à l'intérieur de l'extrémité du tuyau souple, fixée par une bague en aluminium avec une soupape de régulation d'écoulement et un boulon mâle qui est fixé à un tube cylindrique par un boulon femelle et à un brûleur long avec un trou pour l'écoulement du gaz. A l'intérieur du tube cylindrique se trouve une aiguille avec une protubérance et un trou et une bague d'étanchéité sur l'aiguille conique avec un trou et, sur celles-ci, un ressort sous pression contraint par un fil galvanisé passant à travers le trou sur l'aiguille. Sur l'extrémité supérieure du fil galvanisé un manchon de pression est attaché à une corde en nylon qui s'étend à l'intérieur du tuyau souple jusqu'à l'extrémité supérieure.

CLAIMS
VALVE WITH ECONOMY DEVICE AND GAS FLOW INTERRUPTION IN
CASE OF FIRE ON THE HOSE
CHARACTERIZED BY a metallic valve with a device, it
comprises a cylindrical tube with a female bolt and burners with male bolts
and ends to be connected to the hose; with a flow-reduction and gas economy
ring, the flow-interruption device inside the valve is activated when there is
a
fire on the hose. An aluminum ring (1) on the lower end of the hose (3)
connected to the flow-regulating valve (4) and a metallic ring with a flow and

economy device (2) inside the lower end of the hose (3) connected to the
cylindrical tube with a female bolt (7) and to the long burner with a male
bolt
(9) with a hole (15) for gas to flow and over the long burner (9) is attached
to
the hose (3), which is fixed by the aluminum ring (1) inside the cylindrical
tube
with a female bolt (7) and comprises a pressure spring (8) over the needle
with a protuberance and hole (6) with the seal ring (5) with a galvanized
metal
wire (10) to be attached to the hole in the conic needle with a protuberance
(6), which is strained by the nylon string (12) connected by a metal glove
(11)
to the galvanized wire (10) up to the upper end of the hose (3), which goes
through a side hole on the spool with a female bolt (14) and opens the needle
with a protuberance and hole (6) with the seal' ring (5), where the galvanized

wire (10) is blocked by the screw with a bolt and a inside hole to allow flow
(13), blocking the galvanized wire (10) to keep the valve open, which is
mounted on the upper side of the hose (3) with an aluminum ring (1) to
maintain gas flow.

"VALVE WITH ECONOMY DEVICE AND GAS FLOW INTERRUPTION IN
CASE OF FIRE ON THE HOSE"
This patent describes a device used to interrupt gas flow
with a metallic ring that reduces gas flow to the stove, acting as an economy
device. The gas flows in plastic hoses that are exposed to high temperatures
and tend to be damaged. Sometimes a fire can occur; this device is intended
to preserve safety by interrupting the gas flow. It is connected to the flow-
regulating valve on the gas cylinder. The valve with the metallic ring with
the
economy and flow reduction device allows the gas to flow; the nylon string
that strains the spring opens inside the system and is resistant enough to
allow the gas to flow freely inside the hose; it closes when the hose is
breaking or being damaged by high temperatures or by fire. Below is a
detailed description of the valve, referencing the drawings attached.
DRAWING 1: shows a cross-sectional view of the valve with
the device assembled and open.
DRAWING 2: shows a cross-sectional view of the valve with
the device being closed due to a fire on the hose.
According to the drawings, the VALVE WITH ECONOMY
DEVICE AND GAS FLOW INTERRUPTION IN CASE OF FIRE ON THE
HOSE. The valve is made of metal and has lathed, cylindrical parts with male
and female bolts; the aluminum ring (1) is mounted on a lower end of the hose
(3), which is connected to the flow-regulating valve (4) with a male bolt, and
a
metallic ring with a flow and economy device (2) is placed inside the lower
end
of the hose (3) that is connected to the flow-regulating valve; next comes a
cylindrical metal tube with female bolts (7) that is attached to the long
burner
with a male bolt (9) and has a hole (15) for gas to flow, which is connected
to
the upper hose (3), fixed by an aluminum ring (1) to complete the system; the
inside of the cylindrical metallic tube (7) comprises a conic needle with a
protuberance and a hole (6) to attach the galvanized metallic wire (10) with a
pressure glove (11) to connect the galvanized metallic string (10) to the
nylon
string (12); still in the needle with a protuberance and a hole (6), a seal
ring

(5) is introduced; going to the upper end of the hose (3), a metallic spool
(14)
is attached with a female bolt, with a side hole for the string (10) to pass,
which is fixed with a screw (13) with a hole to allow gas to flow; the
aluminum
ring (1) is attached to the upper outside of the hose (3) to attach the inside
spool (14) that supports the strain of the pressure spring (8) to the
galvanized
wire, (10) and the metal glove (11) to the nylon string (12) so that gas can
flow
freely inside the hose (3).
