Abstract

Safety device for fire extinguisher tubes, including fire extinguishers, a head with a fixed handle and a mobile handle whose action releases the pressurized gas located in a small inner tank, gas that is conducted through a closed probe tube at its lower end and affected by radial holes, through which the pressurized gas exits to drive the extinguishing product to the outside through a conduit of the head to quench a fire; characterized in that it comprises at least one closure body that seals the radial holes (3) of the probe tube when the extinguisher is not used; all in order to prevent the entry of dust and other particles through these holes that could totally or partially block the exit of the gas under pressure by said radial holes when using the extinguisher.

Description

Safety device for probe tubes fire extinguishers.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a device safety for extinguisher probe tubes to prevent entry of dust and other particles that could completely or partially small radial gas outlet holes to pressure that is initially housed in a small deposit located inside the extinguisher, so that when it acts on the handle of the extinguisher, the pressurized gas must flow out of the small exit holes of the probe tube to drive the outward extinguishing product to quell a fire.

Background of the invention

Currently there are fire extinguishers, among the which should be noted those that incorporate a linked probe tube to a small tank with gas under pressure, gas that during the use of extinguisher runs through an affected probe tube with radial holes where that gas comes from reaching an interior space of the bottle of the extinguisher where an extinguishing material is located for propel it outside in order to put out a fire.

In some cases, a blockage occurs in the end of the extinguisher probe tube, due to dust ingress or  any other particle blocking the radial holes, with which will cause problems in the correct exit of the gas.

Description of the invention

The safety device for probe tubes extinguishers constituting the object of the invention is characterized because it comprises at least one tubular structure element elastic coupled around a portion of closed probe tube at its free end, while a lower section of it It has at least one radial hole through which a gas under pressure will flow out housed in a warehouse located within the interior space of the extinguisher. The tubular element of elastic structure is located adjusted precisely around that lower section that incorporates the aforementioned orifice or radial holes.

Both the reservoir and the probe tube, as well as a Exhaust product outlet tube are fixed to a head that tightly closes the mouth of the extinguisher, within which the extinction product is found.

Said head also incorporates a fixed handle and another mobile, the latter to release gas from the tank at the time of using the fire extinguisher to put out a fire, so that in this use situation, acting on the mobile handle, the gas released exits through the radial holes of the probe tube towards the interior space of the extinguisher, boosting the extinguishing product outwards through the product outlet tube.

The tubular element of elastic structure is adjusted and tight on the probe tube with a certain pressure to ensure the closing of the radial exit holes in order to prevent the entry of dust and other particles that could clog said radial holes.

When the extinguisher is used, the pressure of the gas deforms the tubular element of elastic structure, achieving total effectiveness in the use of the extinguisher.

Another feature of the invention is that it include means for fixing the elastic tubular element, essentially determined by a clamp, but also could be immobilized by an adhesive or adhesive strip, by example.

Next to facilitate a better understanding of this descriptive report and being an integral part of the same accompany some figures in which with character illustrative and not limiting the object of the invention.

Brief description of the drawings

Figure 1.- Represents a fire extinguisher assembly that  incorporates the safety device for probe tubes extinguishers, object of the invention.

Figure 2.- Shows a sectional view of the tube extinguisher probe that includes the safety device of the invention.

Figure 3.- Represents another sectional view of the probe tube where the safety device is shown in extinguisher use position.

Description of the preferred embodiment

Considering the numbering adopted in the figures, the safety device for extinguisher probe tubes  it comprises a tubular element like a jacket 1 that is coupled around a lower section of a probe tube 2 in correspondence with radial holes 3 located in that section bottom, holes 3 where a pressurized gas will exit, such as CO_ {2}, housed in principle in a small tank 4 fixed to a head 5 that tightly closes the mouth of a bottle 6 of the extinguisher where the extinction product is located.

Inside this bottle 6 is the product of extinction, as well as the probe tube 2, gas tank 4 to pressure and an outlet tube 7 of that product also attached to the head 5.

This head 5 also incorporates other elements known, such as a fixed handle 8 and another mobile 9 associated with a needle mechanism to release the gas under pressure from the small tank 4, so that when the extinguisher is used for put out a fire or fire, after releasing a ring security not represented in the figures, you can act on the mobile handle 9 to release the gas from the tank 4, gas that will leave pressure through the radial holes 3 of the probe tube 2, pressure of the gas that will reach inside the bottle 6 affecting the product of extinction that will ascend through the outlet pipe 7 until reaching the extinguisher head through a conduit of said head 5 To put out the fire.

Shirt 1 is an element of elastic structure which is normally attached to a portion of the closed probe tube 2 at its free end, so that when use is made of extinguisher, the gas pressure will deform the elastic jacket 1 being able to leave the gas inside the bottle without any problem 6.

The tight fitting of elastic shirt 1 on the tube probe 2 prevents the entry of dust and particles that could cause partial or total sealing of radial holes 3 and therefore avoid a malfunction of the whole fire extinguisher when using it.

The jacket 1 is fixed to the probe tube 2 by a clamp 10 that radially presses said jacket 1 to Secure your immobilization.

Claims (3)

1. Safety device for extinguisher probe tubes, which including fire extinguishers a head with a fixed handle and a mobile handle whose action releases the pressurized gas located in a small interior tank, gas that is conducted through a closed probe tube by its lower end and affected by radial holes, through which the gas under pressure exits to propel the extinguishing product to the outside through a conduit of the head to quell a fire; It is characterized in that it comprises at least one closing body that seals the radial holes (3) of the probe tube when the extinguisher is not used; all this in order to prevent the entry of dust and other particles through those holes that could block all or part of the pressure gas outlet through said radial holes when using the extinguisher. 2. Safety device for extinguisher probe tubes according to claim 1, characterized in that the closure body consists essentially of a tubular element of elastic structure (1) as a tight-fitting jacket and hugged to a portion with radial holes (3) of the probe tube (2); all this in order that during the use of the extinguisher the pressure of the gas deforms the elastic jacket (1) allowing the exit of said gas. 3. Safety device for extinguisher probe tubes according to claim 2, characterized in that the tubular element of elastic structure (1) is fixed to the probe tube (2) by means of a clamp (10) that radially presses the jacket (1) against the probe tube (2).
