Problems solved by technology
[0003] However, none of the existing ozone aging test chambers on the market is equipped with an ozonated gas flow rate adjustment device. Therefore, for the ozone aging test of samples of different materials, the final detection results will bring great uncertainty in the entire ozone aging test. Sexuality, resulting in large differences in the test results of related products
If the relevant test products are tested under the above equipment conditions, it may not be possible to find problems with product quality, resulting in serious product quality accidents

The invention discloses a device and method for adjusting the flow rate of ozonized gas in an ozone aging oven. The ozone aging oven comprises an inner cavity; a flow diffusion plate is arranged on the top face of the inner cavity; a plurality of flow diffusion holes are formed in the flow diffusion plate; flow baffles are arranged on the flow diffusion holes; and the flow baffles are connected with a synchronous horizontal moving mechanism; the synchronous horizontal moving mechanism is connected with a PLC; the device further comprises a gas flow monitor; and the gas flow monitor is further connected with the PLC. The method comprises the following steps: firstly, collecting ozonized gas flow Q; secondly, calculating the area S of diffusion holes through which airflow can pass; acquiring the flow velocity of the ozonized gas according to the calculation formula V = Q / S of the flow velocity V of the ozonized gas; comparing the flow velocity of the ozonized gas with the permissible range of the flow velocity of the ozonized gas preset in the PLC; and if the flow velocity of the ozonized gas is not within the permissible range, horizontally moving the flow baffle to adjust the area S of the flow diffusion holes through which airflow can pass until the flow velocity of the ozonized gas is within the permissible range.
Description
technical field [0001] The present invention relates to the detection technology of gas flow rate, more specifically, relate to a kind of air inlet flow rate less than 95L / min, the ozone gas generation system flow rate less than 5L / min in the ozone aging test box in the regulating device of the ozonated gas flow rate and its adjustment method. Background technique [0002] The ozone aging chamber is an environmental test equipment that provides an ozone accelerated aging simulation environment for the tested sample and judges whether the tested sample meets the ozone resistance performance. It is widely used in the fields of rubber and plastics, automobiles, textiles, wires and cables, and new energy. The flow rate of the ozonated gas in the chamber shall be large enough to prevent the decrease of the ozone concentration caused by the aging consumption of the test. The rate of ozone depletion varies with the rubber used, test conditions, and other test details. Therefore, ...
