Abstract

The sampling device contains a sampling bag, a pressure sensor (P), two electrically controlled changeover valves (EV1) (EV2), switches (I1,I2), a timer (T) and indicating lamps (L1,L2). The sampling bag is first evacuated and then filled from the atmosphere. Evacuation of the sampling bag is effected by closing he first switch (I1) and turning the second (I2) to the vacuum position. The pump starts and the position of the changeover valves (EV1) (EV2) causes evacuation of the sampling bag terminated by a pressure sensor (P). The sampling bag is filled by turning the second switch (I2) to the fill position such that the changeover valves (EV1) (EV2) fill the bag from the outside atmosphere.

Description

VA@@SE AUTONOME DE PRÉLÉVEMENT DE GAZ
La p@esente invention do@cerne un dispositir de prélevement de gaz dans des@sac enanches à l'aide @ une valise autoneme.VA @@ SE AUTONOMOUS GAS SAMPLING
The present invention relates to a device for sampling gas from waterproof bags using a self-contained suitcase.

L'@nalyse des gaz@d'envtronnement s'ettectue génécalement sa@ place à l'aide de materiel sophistique et conteux (analyseurs de gaz), ce matériel place dans un véhicule ne permet pas d'approcher toutes les zones contaminees ou polluées pour remédier à ces inconvénients nous proposons une valise autonome rechargeable permettant de stocker les gaz incrimines dans des saes qui après reperage pourront étre analysé en laboratoire. The @ gas analysis of the environment is generally performed on its place using sophisticated and countable equipment (gas analyzers), this material placed in a vehicle does not allow to approach all contaminated or polluted areas To remedy these drawbacks, we offer a self-contained rechargeable suitcase allowing the incriminated gases to be stored in saes which, after tracking, can be analyzed in the laboratory.

La valise est constituee de deux compartiments
@) Compartiment de prélèvement
Le compartiment de prélèvement comprendra:
a) Une @om@e de prélèvement de gaz et de vidange des saes
b) Deux électrovannes permettant soit la vidange soit le remplissage des sacs @) Un Un filtre d'entre pour eviter l'encrassement de
La pompe
d) Une temporisation du temps de prélèvement pour éviter l'éclatement des sacs
e) Un pressostat pour le contrôle de l'étanchéité es sacs.The suitcase is made up of two compartments
@) Collection compartment
The collection compartment will include:
a) A @ om @ e for gas sampling and emptying of saes
b) Two solenoid valves allowing either the emptying or the filling of the bags @) One A filter of entry to avoid the clogging of
The pump
d) A delay in the sampling time to avoid bursting of the bags
e) A pressure switch for checking the bags' tightness.

:) Un raccord rapide et etancle cour le branchement et l'échange rapide des sacs. :) A quick and watertight connection during connection and quick exchange of bags.

g)Une alimentation autonome rechargeable pour le fonctionnement de la valise
2) Compartiment de stockage.g) An autonomous rechargeable power supply for the functioning of the suitcase
2) Storage compartment.

Le compartiment de stockage comprendra Le sac de récupération des gaz placé a l'intérieur de la valise cour eviter toute déchirure et relié a elle ci par le raccord rapide et tanche permettant ainsi le remplacement rapide de dernier et l'intégralité des composants des gaz préleves.  The storage compartment will include The gas recovery bag placed inside the backpack avoid any tearing and connected to it by the quick and tight connection thus allowing rapid replacement of the last and all of the components of the sampled gases .

FOUCTIONNEMENT DH LA VRL@SE @chémas 1/3 2/3 3/3)
Avant de prélever les gaz à analyser @l est @ecessaire de s'assurer que le sac de prélèvement soit vide et étanche,nous effectuérons pour cela un controle d'étanchéité du sac avant prélèvement. OPERATION DH LA VRL @ SE @ chémas 1/3 2/3 3/3)
Before sampling the gases to be analyzed @ it is @ necessary to make sure that the sampling bag is empty and watertight, we carry out for this a leak tightness check of the bag before sampling.

Controle de l'étanchéité du sac. (Schéma 1/3)
Four effectuer le contrôle d'étanchéité il faut mettre en marche la valise pour cela on ferme l'interrupteur général (Il) la lampe temoin (L1) de fonctionnement s'allume,on place alors l'intérrupteur (@2) sur la çosition (vidange) ce faisant on met en marche la pompe directement et on enclenche les electovannes trois voies (EV1 et EV2) ,la pompe tournera tant que Le sac ne sera pas vide lorsque le sac sera vide un témoin de vidange (L2) s'allumera commandé par le pressostat (P) et arrétera la pompe,si la lampe témoin (L2) reste allumée après l'arrèt de lapompe celà signifie que le sac est étanche et que ncus pouvons commencer le prélèvement des gaz.Checking the tightness of the bag. (Diagram 1/3)
Oven carry out the tightness control you have to turn on the suitcase for this you close the general switch (II) the indicator lamp (L1) for operation lights up, then place the switch (@ 2) on the position (emptying) by doing this the pump is started directly and the three-way solenoid valves (EV1 and EV2) are switched on, the pump will run as long as the bag is not empty when the bag is empty a drain indicator (L2) s' will turn on controlled by the pressure switch (P) and will stop the pump, if the pilot light (L2) remains on after the pump has stopped this means that the bag is sealed and we can start sampling gases.

Prélèvement des gaz. Schema 2/3)
Pour prélever les gaz il suffit de placer l'interrupteur (12) sur la position remplissage å ce moment on met en -narche uniquement la pompe en passant par une temporisation (T) de prélèvement le remplissage du sac s'ettectuera durant le temps de temporisation programmé vitant ainsi l'eclatement du sac des crue le sac est rempli nous ouvrons la valise et nous remplaçons le sac le gaz stocké dans le sac de prélèvement est préservé par le raccord étanche et peut être ainsi dirigé sur un laboratoire d'analyse. Gas sampling. Figure 2/3)
To sample the gases, simply place the switch (12) on the filling position. At this moment, the pump is only started by passing through a sampling delay (T). The filling of the bag will be performed during the programmed time delay thus seeing the bursting of the flood bag the bag is filled we open the bag and we replace the bag the gas stored in the sampling bag is preserved by the tight connection and can thus be directed to an analysis laboratory.
