摘要:
The invention pertains to an overflow device (10) for a liquid container with a fill line (20) whose outlet (28) extends into an opening in the ceiling of the container, an overflow (16) which is formed by the ring-shaped open area that remains around the fill line (20), and a valve body (32) for the opening and closing of the overflow (16), which is installed on the fill line in such a manner that it can be axially slid, and which is positioned in the respective direction for closing the overflow by means of a tension element (52). The valve body (32) contains a chamber with a closed bottom (34), a perimeter wall (36), and an opening that is demarcated by the perimeter wall (36), into which the outlet (28) of the fill line (20) is placed, and the valve body (32) further comprises an outer jacket (38) adjacent to the exterior of the perimeter wall (36) for the purpose of closing the overflow (16). The perimeter wall (36) is designed with at least one opening (40), which is closed by the outer wall (46) of the fill line (20) in the closed position of the overflow (16).

L'invention concerne un dispositif de mise à l'air libre pour une citerne (2) comportant au moins une extrémité proximale (4) destinée à être reliée avec l'intérieur de ladite citerne et une extrémité distale (5) à l'air libre, ledit dispositif comprenant à son extrémité distale (5) un bouchon (9) étanche mobile entre une position de fermeture et une position d'ouverture, ledit bouchon étant monté sur un levier (14) entraîné en rotation par une tige (13) solidaire d'un élément d'actionnement manuel (12) pouvant être monté en rotation sur le châssis de la citerne (2) entre une position de fermeture correspondant à la position de fermeture du bouchon (9) et une position d'ouverture, dans laquelle la rotation de l'élément d'actionnement manuel (12) entraîne la rotation du levier (14) de sorte à placer le bouchon (9) dans sa position d'ouverture.
摘要:
A method for safely managing flammable substances contained in a transport vehicle (1), said vehicle (1) comprising at least one volume to be ventilated (V v ) susceptible of containing a mixture of explosive vapours or gases comprises the steps of: - putting the volume to be ventilated (V v ) into communication with the atmosphere; - calculating an explosive mixture flow rate (Q dan ) emitted in a liquid and/or solid phase by the flammable substances in contact with the volume to be ventilated (V v ); - actuating a pumping circuit (20) for aspirating an intake flow rate (Q p ) from the volume to be ventilated (V v ); - maintaining the intake flow rate (Q p ) for a purging time (t c ) depending on V v , on a purging number higher than or equal to 10, on the intake flow rate (Q p ) and on the explosive mixture flow rate (Q dan ).

摘要:
The present invention discloses a road tanker with a plurality of tanks (5,7,9) which are individually mounted one behind the other to a vehicle chassis (3) using a flexible mounting system (10) which allows the individual tanks to move with respect to one another in response to flexing of the vehicle chassis. The use of multiple tanks facilitates the use of a sight gauge for determining the quantity of liquid in each tank. The invention also proposes tankers having a unique configuration of tanks (105,107,105) which are each horizontally symmetrical and in which the opposite ends of each tank are correspondingly curved and wherein adjacent tanks have complimentary curved ends to allow close nesting of the tanks. Also described is a vapour recovery system.
摘要:
An automated tanker unloading system (10) has a plurality of electronically controlled valves (28) to control gas pressure within a tanker trailer (16) and to control the delivery of product. A plurality of electronic gas pressure transducers (40) sense internal gas pressure within individual hoppers (18) of the trailer and sense internal gas pressures within a hot hose (14) and a product hose (24) and convert the sensed gas pressure into an electronic signal. A plurality of pressure carrying pipes (42) transmit positive and negative pressures between the valves and the hoppers and the product hoses and the hot hose. A processor (44) is programmed to analyze electronically inputted data from the transducers and to then send signals to control the valve functions.
