VEHICLE-PROCESS EXPLOSION-PROOF CONTAINER Russian patent published in 2016 - IPC F42D5/45 F16K17/40 

FIELD: blasting.

SUBSTANCE: invention relates to storage and transportation of explosive substances (ES) and explosive, flammable liquid cargo. Proposed explosion-proof container includes vessel in form of metal tank with filling and emptying. Vessel is made in form of vertical cylindrical housing with elliptical cover and conical bottom, protective basket of pipes, wherein vessel is made of aluminium with yield point of not more than 155 MPa. Ratio of wall thickness to inner diameter of cylindrical part makes 0.003…0.004, and bottom taper angle is approximately 90°. Protective basket attachment points are located on cylindrical housing. Explosion-proof device is provided with safety indicator on breaking element mounted in hatch of container elliptical cover and comprises valve body, heat-insulating and disruptive elements, lined load gate covering hole in body of protected object. In upper cylindrical part of valve body there is heat-insulating element and sealing membrane pressed to valve body by cover articulated with lever interacting with baffle plate, and attachment point of breaking element is fixed with its upper part on lever, and lower part on upper cylindrical part of valve body. Breaking element consists of wire, locking bolt, fork, valve cover lever, nuts, two drums, located respectively in fork of valve cover plate lever and in upper cylindrical part of valve body. Wire ends are inserted into holes of drums and then, wound on them. Gap h between forks is about (1.5÷3) of wire diameter, and parameters of valve are within following optimum intervals of values: c = H/Dy = 2.5÷3.0, where Dy is diameter of upper cylindrical part of valve body, equal to maximum size of holes of housing of protected object; H is height of valve assembly. On wire of breaking safety indicator element is fixed in form of sensor responding to deformation, for example resistive strain gauge, output of which is connected with signal amplifier, for example strain-amplifier, and output of strain-amplifier is connected to input device warning on emergency situation. Wire breaking element, on which there is safety indicator sensor is made elastic and has several turns in part connected with safety indicator sensor.

EFFECT: invention allows improving explosion safety of container.
