The inflatable shaft and the inflatable sleeve are extremely convenient and convenient to use. You only need to prepare your own air source. The air pressure is controlled within the range of 6-8kg/cm2. When you need to lock the external parts (for example, a circular paper tube), you only need to The air gun can be inflated by facing the air nozzle on the inflatable shaft. It can withstand the external parts (such as a circular paper tube). When the paper needs to be discharged, press down the sliding external parts on the air nozzle by hand (such as The round paper tube) can be taken out.
Since the use of inflatable shafts requires relatively high gas pressure, there are also many requirements for the gas nozzle of inflatable shafts:
1. The air-tightness of the air nozzle should be good, which can ensure that the air nozzle is inflated and deflated during the two-second inflation time of the inflatable shaft, and the internal air pressure is ensured, otherwise it cannot provide useful air pressure.
2. The quality of the gas nozzle should be good. Most of the gas nozzle data use copper as the basic data. Because it is under pressure of 3-4 atmospheres, the pressure resistance is relatively high and the production is more convenient.
3. Pay attention to the use of air nozzles. Since only the inflatable rod is needed to face the air nozzle on the inflatable shaft, the inflatable shaft can be successfully inflated. Therefore, the requirement for the rapid inflation and exhaust function of the air nozzle is relatively high.
