Abstract

The gas tank (1) has its protection equipment housed in a shaft (2). The shaft has a saddle (3) which fits the shape of part of the external surface of the tank by which it is mechanically fixed to the tank by a nut and bolt or by webbing (8). A sealing joint (7) is interposed between the tank and the saddle. A pump (10) enabling evacuation of water is housed inside the shaft and communicates with the outside through a pipe (11). A safety valve (12), an emptying valve (13) and a filling valve (14) are also housed in the shaft.

Description

Citerne à puits d'équipement étanche
Une citerne de gaz enterrée se distingue des citernes aériennes par divers aménagements ayant trait en particulier à leur protection contre la corrosion et à l'accès aux divers équipements nécessaires à l'exploitation dont est pourvue la citerne : clapet de remplissage, robinet de départ gazeux ou liquide, jauge, soupape de sécurité, détendeur etc...
Watertight equipment well tank
A buried gas tank differs from above-ground tanks by various arrangements relating in particular to their protection against corrosion and to access to the various equipment necessary for the operation of which the tank is provided: filling valve, gas flow valve or liquid, gauge, safety valve, regulator etc ...

La protection de ces équipements contre l'humidité revêt une grande importance car l'eau peut provoquer des détériorations mettant en danger l'exploitation de la citerne : corrosion des soupapes et des clapets, blocage des détendeurs etc... The protection of this equipment against humidity is of great importance because water can cause deterioration endangering the operation of the tank: corrosion of valves and valves, blocking of regulators etc ...

Ces équipements sont généralement logés dans un "puits" dont l'ouverture est au-dessus du niveau du sol et qui vient s'appliquer sur le corps de la citerne. These pieces of equipment are generally housed in a "well", the opening of which is above ground level and which is applied to the body of the tank.

L'invention vise une citerne dans laquelle on parvient à empêcher l'eau, la boue ou la terre de pénétrer dans le puits d'équipement d'une manière simple, sans nécessité d'une double coque. The invention relates to a tank in which it is possible to prevent water, mud or earth from entering the equipment well in a simple manner, without the need for a double hull.

Suivant l'invention, le puits d'équipement comporte une selle qui épouse la forme d'une partie de la surface extérieure de la cuve, notamment de la surface extérieure supérieure de celle-ci, et par laquelle le puits est fixé mécaniquement à la cuve. Un joint d'étanchéité est interposé entre la cuve et la selle. According to the invention, the equipment well comprises a saddle which follows the shape of a part of the external surface of the tank, in particular of the upper external surface thereof, and by which the well is mechanically fixed to the tank. A seal is interposed between the tank and the saddle.

Grâce à la présence de la selle, le joint interposé entre celle-ci et la cuve s'applique bien à la cuve et assure une bonne étanchéité. On empêche ainsi toute entrée d'eau dans le puits d'équipement par le bas à la suite d'une remontée de la nappe phréatique ou d'une inondation.  Thanks to the presence of the saddle, the seal interposed between it and the tank applies well to the tank and ensures a good seal. This prevents any entry of water into the equipment well from below following a rise in the water table or a flood.

On peut fixer mécaniquement le puits à la cuve par des goujons issus de la cuve et coopérant avec des écrous. On peut également, suivant un mode de réalisation qui n'implique aucun soudage et qui permet ainsi de transformer une citerne aérienne en une citerne destinée à être enterrée, fixer le puits à la cuve au moyen de sangles appliquées à la selle et au fond de la cuve. The well can be mechanically fixed to the tank by studs coming from the tank and cooperating with nuts. It is also possible, according to an embodiment which does not involve any welding and which thus makes it possible to transform an aerial tank into a tank intended to be buried, fix the well to the tank by means of straps applied to the saddle and to the bottom of tank.

Suivant un mode de réalisation particulièrement achevé, il est prévu un dispositif d'évacuation de l'eau contenu dans le puits d'équipement. Si de l'eau pénètre ainsi par le haut dans le puits d'équipement ou s'accumule par condensation, ce dispositif l'évacue et le puits d'équipement reste ainsi, comme il se doit, parfaitement à l'abri de l'eau. According to a particularly completed embodiment, there is provided a device for discharging the water contained in the equipment well. If water so penetrates from above into the equipment well or accumulates by condensation, this device discharges it and the equipment well thus remains, as it should, perfectly protected from the water.

Aux dessins annexés, donnés uniquement à titre d'exemple, la figure 1 est une vue partiellement en coupe d'une citerne suivant l'invention et, ies figures 2 et 3 sont des vues en coupe de deux parties de la figure 1. In the accompanying drawings, given solely by way of example, FIG. 1 is a partially sectional view of a tank according to the invention and, FIGS. 2 and 3 are sectional views of two parts of FIG. 1.

La citerne représentée à la figure 1 comprend une cuve 1 en acier résistant à la pression à la surface supérieure de laquelle est fixé un puits 2 d'équipement en matière plastique. Ce puits 2 comporte une selle 3 dont la face inférieure épouse la forme d'une partie de la surface extérieure supérieure de la cuve 1. A la partie gauche de la figure 1 et à la figure 2, le puits 2 d'équipement est fixé à la cuve 1 par un goujon 4 issu de la cuve et coopérant avec un écrou 5 de manière à serrer la selle 3. Dans celle-ci est ménagée une cavité 6 ouverte vers la face supérieure de la cuve 1 et recevant un joint 7 d'étanchéité. A la figure 3, le système à goujon 4 et écrou 5 est remplacé par une sangle 8 qui fait le tour de la cuve en s'appuyant sur le fond 9 de celle-ci. The tank shown in Figure 1 comprises a tank 1 of pressure-resistant steel to the upper surface of which is fixed a well 2 of plastic equipment. This well 2 includes a saddle 3, the lower face of which follows the shape of a part of the upper external surface of the tank 1. On the left part of FIG. 1 and in FIG. 2, the equipment well 2 is fixed. to the tank 1 by a stud 4 coming from the tank and cooperating with a nut 5 so as to tighten the saddle 3. In this is formed a cavity 6 open towards the upper face of the tank 1 and receiving a seal 7 d sealing. In Figure 3, the stud system 4 and nut 5 is replaced by a strap 8 which goes around the tank by resting on the bottom 9 thereof.

Une pompe 10 ou autre dispositif permettant d'évacuer de l'eau est logée à l'intérieur du puits 2 et communique avec l'extérieur par un conduit 11, étant entendu que la pompe pourrait être logée aussi à l'extérieur du conduit 2. A pump 10 or other device making it possible to evacuate water is housed inside the well 2 and communicates with the outside by a conduit 11, it being understood that the pump could also be housed outside the conduit 2 .

Dans le puits 2 d'équipement, on reconnaît sur la cuve 1 une soupape de sécurité 12, un robinet de départ 13 et une valve de remplissage 14.  In the equipment well 2, there is recognized on the tank 1 a safety valve 12, a flow valve 13 and a filling valve 14.
