Abstract
Description
Mon invention concerne un appareil simple et robuste sécurisant l'emploi et la manipulation de gaz propane liquéfié, caractérisé en ce qu'il est formé d'un cylindre (1) fixé au robinet ou vanne (2) et d'une réserve (3) de gaz propane liquéfié, ledit appareil permettant de contrôler ou de bloquer la libération naturelle (4) dudit gaz propane liquéfié par le piston coulissant (5) asservi d'un fort ressort (6) et ayant un orifice de contrôle<B>(7)</B> de pression à une assistance hydraulique, pneumatique ou gazeuse qui comprime le ressort de sécurité et comportant en (8) un orifice atmosphérique pour la libre efficacité dudit ressort. My invention relates to a simple and robust device securing the use and handling of liquefied propane gas, characterized in that it is formed of a cylinder (1) attached to the valve or valve (2) and a reserve (3). ) of liquefied propane gas, said apparatus for controlling or blocking the natural release (4) of said liquefied propane gas by the sliding piston (5) slaved with a strong spring (6) and having a control port <B> ( 7) </ B> of pressure to a hydraulic, pneumatic or gaseous assistance which compresses the safety spring and comprising in (8) an atmospheric orifice for the free effectiveness of said spring.
Le dessin annexé illustre l'invention. La figure 1 représente en coupe, une mise en aeuvre de ce dispositif. The accompanying drawing illustrates the invention. Figure 1 shows in section, an implementation of this device.
La pression de libération du gaz propane liquéfié, qui sort de sa réserve importante, étant faible est retenue par un ressort de forte puissance. The release pressure of liquefied propane gas, which comes out of its important reserve, being low is retained by a high power spring.
Par l'assistance hydraulique, il est possible de libérer ce combustible, par un ressort qui va comprimer, combustible qui va servir au désherbage thermique des plantes adventices dans les cultures agricoles, toutes corporations confondues.By hydraulic assistance, it is possible to release this fuel, by a spring that will compress, fuel that will be used for thermal weeding of weeds in agricultural crops, all corporations combined.
Ce volume, réserve de propane liquéfié, est supérieur ou égal à 300 kilogrammes pour une autonomie d'emploi d'une journée .Il est obligatoire d'avoir une sécurité absolue, même si petit soit-il. This volume, liquefied propane reserve, is greater than or equal to 300 kilograms for a one-day employment autonomy. It is mandatory to have absolute security, even if it is small.
Si un incendie se déclenche avec l'aide des plantes déshydratées il faut stopper immédiatement la sortie de la réserve de propane liquéfié qui alimente les chalumeaux d'un coup net par la baisse de pression hydraulique, le ressort faisant sa fonction. If a fire is triggered with the help of dehydrated plants it is necessary to immediately stop the exit of the liquefied propane reserve which feeds the torches with a sharp blow by the fall of hydraulic pressure, the spring doing its function.
