Description

Technical Field

[0001] The present invention relates to the technical field of isolation suit detection, and more specifically, to an isolation suit air permeability detection device and a detection method. Background Art

[0002] The isolation suit air permeability test device is a special device used to test the air permeability of isolation suits. According to the specified method and test parameters, the sample is clamped on the air inlet of the fabric air permeability tester, and then the fan speed is adjusted to make the two sides of the fabric reach the specified pressure difference. The air permeability of the fabric is measured according to the nozzle aperture and the pressure difference between the two sides. The air permeability refers to the air flow rate that flows vertically through the unit area of ​​the fabric per unit time under the specified pressure difference between the two sides of the fabric.

[0003] Chinese patent document (CN117782942B) discloses a protective clothing air permeability simulation detection device, which states in the specification that "the protective clothing air permeability simulation detection device, by setting a cover body mechanism and a positioning assembly, the positioner is opened to loosen the fixation of the second clamping plate to the first clamping plate, at this time, the cloth can be evenly laid on the top of the detection tank, and the first clamping plate and the second clamping plate are turned upward along the first rotator, so that the first clamping plate and the second clamping plate are clamped outside the cloth and the detection tank, and the first clamping plate and the second clamping plate are fixed by the positioner. Since the use of the device as a whole only needs to cooperate with the sealing cover and fix the cloth to be put into use, it not only reduces the difficulty of using the device, but also has a simple structure, low technical requirements for personnel, and low requirements for materials for processing the device. Therefore, the cost of the device is low, which is not only convenient for large-scale promotion, but also effectively guarantees the detection efficiency of protective clothing." However, in actual use, it is difficult to avoid dust from entering the detection equipment, affecting subsequent detection data, and on the other hand, the fixed structure is simple and there is a gap between the cloth and the equipment, resulting in gas leakage that affects data detection again;

[0004] Most of the testing equipment on the market is relatively large in size, which not only limits its convenience of use, but also increases the cost of use accordingly. In contrast, although small testing equipment is lighter, it usually uses threaded fixing to install the fabric, and the friction generated in this process often causes unnecessary damage to the fabric. Therefore, existing testing equipment faces two major challenges: one is that it is difficult to meet the needs of low-cost and portable testing; the other is that it is easy to damage the fabric during the test process, thereby affecting the accuracy of the test data. In addition, after the test is completed, these devices often lack effective protection measures, which makes it easy for impurities such as dust and hair to enter the inside of the equipment, which will not only shorten the service life of the equipment, but may also further affect the accuracy of subsequent test data. In view of this, we propose an isolation suit air permeability detection device and detection method. Summary of the invention

[0024] A method for using an isolation suit air permeability detection device comprises the following steps:

[0025] S1. When in use, the sealing component and the adjusting component are pulled out along one side of the shell component, the fabric to be tested is placed on the other side of the shell component, and then the sealing component is installed on the other side of the shell component. During the process of fixing the sealing component by the friction between the sealing component and the shell component, the isolation component will be squeezed and the air inside it will be discharged into the pressing component, so that the pressing component will extend and fit and adsorb with the adjusting component, thus completing the fixing of the fabric. Then, the testing component can be started to test the air permeability of the fabric.

[0026] S2. When not in use, the sealing component and the regulating component need to be inserted into the shell component on the side with the sealing baffle. After insertion, the sealing component will be fixed by the friction between it and the shell component, and the sealing baffle will enter the sealing component to complete the sealing of the sealing component, and the isolation component on the other side of the shell component will seal the shell component. When in use, after the sealing component is installed to the other side of the shell component, the sealing component will squeeze the isolation component, so that the other side of the shell component can allow gas to circulate, and the side without the sealing component will also remain in a circulatory state;

[0027] S2.1. When in use, after pulling out the sealing cover from one side of the sealing shell, it needs to be inserted into the other side of the sealing shell. During this process, the cloth is placed between the sealing cover and the sealing shell. As the sealing cover continues to move, the sealing tube will enter the second conical shell and squeeze the push plate, so that the push plate squeezes the piston plate and the isolation plate through the sliding rod when moving, so that the isolation plate is separated from the second conical shell and enters the first conical shell. At this time, the gas can be discharged along the first conical shell and the second conical shell. Since the piston plate pushes the air inside the sliding sleeve into several sealing tubes when moving, it pushes the first elastic telescopic rod to extend, thereby squeezing the adsorption block to fit the magnetic block;

[0028] S2.2. After use, the sealing cover needs to be fixed and the handle needs to be turned so that the handle drives the rotating piece and the limiting ring to rotate in the limiting groove. At this time, the inclined block on one side of the magnetic block will squeeze the inclined groove on one side of the insulating block, so that the magnetic block squeezes the second elastic telescopic rod to contract, so that the magnetic block is away from the adsorption block and is misaligned with it. At this time, you need to pull the handle to pull the sealing cover out of the sealing shell.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention designs a sealing component, an isolation component and a sealing baffle. When the sealing component is installed to the other side of the shell component in the use state, the sealing component will squeeze the isolation component, so that the other side of the shell component can allow gas to circulate, and the side without the sealing component installation will also maintain a circulation state, so that the device does not need too much adjustment when in use, and only needs to squeeze the sealing component to complete the connection between the two ends of the shell component. When it is not in use, the sealing component needs to be reset, which can not only quickly complete the installation and disassembly of the fabric, but also ensure that the shell component is in a sealed state when not in use, avoiding the entry of outside air, thereby reducing the entry of waste and impurities in the air into the device, thereby ensuring the data accuracy and service life of the device during detection.

[0031] 2. The present invention also designs a sealing component, a pressing component and an isolating component. After the sealing cover is pulled out from one side of the sealing shell, it needs to be inserted into the other side of the sealing shell. During this process, the cloth is placed between the sealing cover and the sealing shell. When the push plate moves, it squeezes the piston plate and the isolating plate through the sliding rod, so that the isolating plate separates from the second conical shell and enters the first conical shell. When the piston plate moves, it pushes the air inside the sliding sleeve into several sealing tubes, thereby pushing the first elastic telescopic rod to extend, thereby squeezing the adsorption block and the magnetic block to fit together, so that the device does not need to use threads or additional clamping components to complete the fixation and sealing of the cloth, which reduces the difficulty of using the device and avoids gas leakage and error in detection data caused by magnetic adsorption.

[0032] 3. The present invention also fixes the sealing cover and rotates the handle by designing an adjustment component and a pressing component, so that the handle drives the rotating plate and the limit ring to rotate in the limit groove. At this time, the inclined block on one side of the magnetic block will squeeze the inclined groove on one side of the insulating block, so that the magnetic block squeezes the second elastic telescopic rod to contract, so that the magnetic block is away from the adsorption block and misaligned with it. At this time, it is necessary to pull the handle to pull the sealing cover out of the sealing shell. On the one hand, the magnetic block can enhance the effect of fixing the cloth and avoid gas leakage. On the other hand, it reduces the steps of installation and disassembly, reduces the difficulty of using the device, meets the low-cost detection needs, and has promotion significance.
