Definitions
- the invention relates to a security device. anti-high pressure intended for fire extinguishers.
- Fire extinguishers feature so known a reservoir containing the product to be sprayed, of which the opening is closed by a distribution head which supports a closed cartridge of pressurized gas as we see it in particular on FR-A 2340107.
- a striker on a sealing cap of an orifice of this cartridge, this is immediately put into communication with the reservoir by establishing a high pressure therein capable of chase the extinguishing agent out to a spray rod connected to a through-hole provided in the head distribution.
- the latter also serves as a support for striker trigger mechanisms including the lever usual presser and its pin or its control ring and security.
- the dispensing head which is a part round coming from foundry or machining, is firmly fixed, for example by screwing, on the opening of the tank. Sealing is ensured by an annular seal housed in a peripheral groove in the head. During the tightening, the seal is crushed against the circular edge of opening the tank.
- the invention provides a simple and effective which allows, when such an overpressure is established thus in the tank, to avoid the disadvantages indicated above because it will settle in said head a leakage to the outside, as soon as the overpressure has exceeded one predetermined threshold.
- the invention therefore relates to a device for anti high pressure safety for fire extinguisher including the dispensing head is tightly fixed to the tank containing the product to be sprayed, sealing being provided by a seal housed in an annular groove of said head, the seal being intended to be crushed on a tank neck when the head is closed, device according to which the edges of the annular groove in which is positioned the seal are each dug a notch on either side of the joint, one opposite the other.
- Figure 1 a perspective view of a head distribution for fire extinguisher and figure 2 the same view showing the seal in the deformed position.
- Figure 1 shows a dispensing head 1 for fire extinguisher that forms the tank cover containing the product to be sprayed. Said head is crossed by a well 2 connecting the interior of the tank with pressurized gas cartridge no represented. Above the head are also fixed the various mechanisms, including the presser lever and its control ring, striker etc ...
- the peripheral part of the dispensing head usually has an annular groove 3 serving housing a joint 4.
- the seal 4 crashes against the collar upper part of the tank ensuring sealing.
- the inner borders 5 and outer 6 of the annular groove 3 are hollowed out respectively an internal notch 7 and a external notch 8 located one opposite the other.
- This device therefore eliminates any immediate risk and progressive linked to an internal overpressure in the tank, and this in an extremely simple and effective way.
- the internal notch 7 can be of dimension smaller than that of the external notch 8 who must be able to authorize the displacement of the joint towards the exterior, the dimensions being defined according to each type of fire extinguisher.
