DEVICE FOR THE MECHANICAL ASSISTANCE OF THE CLOSURE OF A CONTAINER RESTRAINT PROTOCOL, ON VALIDATION THROUGH A CONTROL TEST BETWEEN THE VALUE OF LOADING IN STORAGE AND THE VALUE OF AN ADVANCE PROGRAMMED TEST LOADING AND ITS PROCESS

摘要

The device of the invention is a storage concept, allowing the hermetic storage under conditions of respect of test load values, programmed in advance, and the device is based on a principle which consists in mechanically slaving the drawdown. of the closure of the receptacle, by stop, without modification of the kinematics of its usual movement, the device for this develops, an airbag connected to a piston system, and a column of liquid in one of the piston chambers, which is the central piston, and the piston emerges, from the outside carries a nut, in which happens a threaded rod, this threaded rod carries at its upper end a stop, and is in free point contact by its lower end with a piece of suspension the suspension piece causes a slider in front of a graduated ruler; and when you want to load the cushion, it is necessary before, adjust the load not to exceed, this is done on the meshing of the threaded rod in the nut, the cursor goes down on the strip, of Okg, on a value given; then we open the valve and load by placing the load on the cushion, and when loaded, the cursor takes this time, the reverse runs to the Okg graduation, and stops before the graduation that gives the value loading done: then there are two possible situations, or the cursor is on Okg, or below 0kg, then the threaded rod can not stop, or the cursor is above Okg, and the threaded rod becomes stubborn .
