The invention relates to a variable-pressure gas explosiveness testing device driven by a double-acting cylinder. The variable-pressure gas explosiveness testing device comprises a testing cylinder body, a first piston, a gas inlet pipeline, a gas outlet pipeline, an ignition element and the like, the double-acting cylinder comprises a double-acting cylinder body and a second piston, and the second piston is movably arranged in the double-acting cylinder body and divides an inner cavity of the double-acting cylinder body into two sub-cavities which are not communicated with each other; and theconnecting rod is connected with the first piston and the second piston. Compared with the prior art, the gas explosiveness testing device can carry out gas explosiveness testing of continuous pressure transformation, and pressure buffering can be achieved when explosion occurs.
Description
technical field [0001] The invention belongs to the technical field of testing devices, and relates to a variable pressure gas explosive testing device driven by a double-acting cylinder. Background technique [0002] In the flammability or explosion test of gas, the configuration of test gas is an important step. At present, there are roughly two configuration methods, one is called the static method, and the other is called the dynamic method. The static method is to evacuate the test container to a near vacuum, and then introduce each gas component successively according to the pressure indication, and the percentage of the gas component can be obtained according to the partial pressure. This method is relatively simple in terms of equipment, but if the test pressure is high, the pressure of the gas source is also required to be high. At the same time, how to make the gas mix evenly is also a difficult point. [0003] The dynamic method of gas distribution is to pass e...
