Abstract

The invention relates to the field of air volume controlling, in particular to a medical air volume adjusting device. The medical air volume adjusting device is installed in a pipeline where air flowsand comprises a fixed control part and a changing control part; the fixed control part comprises a fixed plate radially arranged in the pipeline, a first ventilating hole is formed in the upper portion of the fixed plate, and an air volume adjusting hole is formed in the lower portion of the fixed plate; the changing control part comprises an adjusting plate which is located on the fixed plate downstream, and the middle of the adjusting plate is hinged to the pipeline; a plurality of second ventilating holes are formed in the upper portion of the adjusting plate, and the lower portion of theadjusting plate is provided with a tapered block used for cooperating with opening and closing of the air volume adjusting hole; an air transition cavity is formed between the fixed plate and the adjusting plate, and an exhaust passage is arranged in the adjusting plate in the radial direction and communicates with the air transition cavity; and a one-way valve is arranged at an inlet of the exhaust passage. Through the technical scheme, the effect that when the input air volume is too large, it is ensured that the air volume of a use terminal is within a normal range is achieved.

Description

technical field [0001] The invention relates to the field of gas volume control, in particular to a medical gas volume regulating device. Background technique [0002] When some ventilating equipment is in use, its gas flow rate will suddenly increase or stop suddenly due to unexpected situations, which will cause abnormal phenomena at the end of use. In the prior art, in order to prevent the above problems from occurring, gas flow monitoring is usually installed in the pipeline The device controls the gas flow at the gas outlet of the equipment when the gas flow is found to be too large or stops, so as to achieve the purpose of gas volume adjustment. However, the problem with this method is that it can only be detected and adjusted when there is a problem with the amount of gas flowing into the pipeline, but the abnormal gas has already entered the use terminal. Therefore, it is necessary to design an online regulation of gas flow to avoid the impact of abnormal gas supply...
