Can vacuum measuring system be installed between suction valve and mechanical pump? why

As the name implies, a storage bag is a kind of bag that pumps away air and naturally compresses atmospheric pressure. Simply put, vacuum compression bags are mainly used to hold quilts and various clothes. Its working principle is to draw the air out of the quilt clothes (just like pressing a sponge will shrink) so as to reduce the volume. Do you know which brands of storage bags? What brand of storage bag is good? The top ten brands of storage bags are 1 and Lee Tae (domestic large-scale high-tech household products manufacturer, famous brand in Guangdong Province, high-tech enterprise in Guangdong Province, Zhongshan Lee Tae Household Products Manufacturing Co., Ltd.). 2.

The working principle of the storage bag is to suck the air out of the quilt clothes (just like a sponge will shrink), so that the volume is reduced. The original unfolded quilt and other articles are squashed by atmospheric pressure to isolate the outside air, save space and achieve the functions of dust prevention, mildew prevention, moisture prevention and insect prevention. But although it is a vacuum compression bag, it is not an absolute vacuum. Nowadays, the products generally use vacuum cleaners or manual air pumps to evacuate the air in the bag, which is a new member of the storage family. Vacuum compression bag has the functions of moisture-proof, mildew-proof, moth-proof and odor-proof. The air in compression bags and clothes quilts is pumped out by air extraction tools, reducing the volume and increasing the storage space! How to use the storage bag 1 First of all, before putting the clothes and quilts into the compression bag, dry the clothes and quilts, then fold them into a shape convenient for storage, and put them into the storage bag as far as possible, at least a few centimeters away from the sealing zipper. 2. Before pulling the zipper, check whether the sealing part of the zipper is clean and whether there are fine fibers or dust, otherwise it will cause air leakage in the compression bag. If it is wet, please clean it with a rag. 3. Install the slider, hold down the zipper of the slider by hand, slowly and gently pull it to the other end of the zipper, and when it is pulled to two thirds, squeeze or fold the clothes or quilt to exhaust most of the air, and then quickly pull the remaining one third with the slider. 4. Hold the slider by hand and slide it back and forth several times to ensure that the zipper is really sealed. 5. Manual air pump pumping: Open the air nozzle cover, aim the air pump at the air nozzle opening, and pull the piston to pump air. Note that when pumping large-capacity bags, because the pumping time is a little longer, there is no need to take out the pump and cover it when resting, and the gas will not be sucked back. 6. Suction with a vacuum cleaner: open the air nozzle cover, aim the suction pipe of the vacuum cleaner at the air nozzle opening, and open the vacuum cleaner to quickly pump air and compress it. 7. Open the closed zipper, take out the clothes and quilt to dry, and then restore the original state. The use of the storage bag is very simple. As long as you use it carefully according to the instructions, there will be no big problem and it will also give you a better home environment. Why not? How to choose the material of storage bag 1 and vacuum compression bag: Generally, the adhesion of PET+PE bag is better, and it is also the more material used in bags now-commonly known as high-strength composite film. But the disadvantage of this kind of bag is that it is fragile. In addition, the common mop bags in supermarkets have poor adhesion and are prone to air leakage. They are particularly soft and feel better than other bags. The above is not recommended for everyone to buy. At present, the material of export package is PA+PE. (PS: PA is actually nylon, which is the preferred material at present. The bag made of this material has good flexibility, high adhesion and is not easy to leak, so the cost is relatively high. But although it's a little more expensive, you get what you pay for. As long as it is used well, does not leak after compression and is durable, it will not waste money, right? 2. Which size of vacuum compression bag to buy: which size of vacuum compression bag to buy will determine your use: generally 130 * 90 cm bags are used for thick quilts over 2 meters; 1 10 * 70 cm is used for double thick quilt or two sheets quilt; Two quilts100 * 80cm; 100 * 67 cm for double ordinary quilt; 86 * 55cm can be used for air conditioning quilts, blankets, pillows, down jackets, etc. 80 * 56 cm can hold 2 single pillows, sweaters, etc. 50 * 60 cm can be used to store several clothes such as thin sweaters; 50 * 35cm can be used to store baby clothes or small clothes. Which thickness is better for vacuum compression bag? This is a very critical issue. It is also the reason for the big price difference. Generally speaking, there are three kinds in the market, 0. 06mm, 0. 08mm, 10MM. For home use, the most suitable is 0. 08mm. The price of national ash is moderate and the quality is not bad! 3. Precautions when purchasing vacuum compression bags: Speaking of this, the most crucial point is the basic purpose of purchasing this product, which is to maintain vacuum. Just don't leak air. If there is air leakage, then this product is useless! For us, what if we test it Look at the details first, high-quality bags, general seals and suction valves are also exquisite. If you really don't understand, try it immediately after you buy it, and you can see it the next day or the third day. If it expands, you can return it. 4. How to use the vacuum compression bag: a > Before putting the clothes quilt into the compression bag, please dry it, then fold it into a shape convenient for storage and put it in the bag as far as possible, at least a few centimeters away from the sealing zipper. B > install the slider, press the zipper of the slider by hand, and slowly and gently pull it to the other end of the zipper. C > manually pump air, open the air nozzle cover, aim the air pump at the air nozzle opening, and pull the piston to pump air. D > use the vacuum cleaner to extract air, open the air nozzle cover, aim the suction pipe of the vacuum cleaner at the air nozzle opening, and then open the vacuum cleaner to quickly extract air and compress it. E > open the closed zipper, take out the quilt and dry it, then it can be restored to its original state. 5. Precautions when using the vacuum compression bag ("Suitable vacuum compression bag"-"How to use the vacuum compression bag"): a > Before putting the clothing quilt into the compression bag, it should be dried. B > Don't be near heat sources, fire sources and other places, and don't use nails, needles and other hard objects to directly contact the compression bag to avoid damage. C > Please use down products as little as possible, because there are always some hard feather tubes in down products. When vacuum is sucked in for compression, these hard stems will drill out of quilts and clothes like "lotus leaves wrapped in nails", and may cause air leakage in compression bags. D > if the zipper part of the compression bag is often bent, it will be deformed, which will reduce the sealing performance. If fine fibers and dust enter the zipper, the sealing performance will be reduced. Please clean it with gauze soaked in water and zip it up. E > The compression rate and recovery rate of clothing quilts will vary with different materials.
