What are the specifications of the inflatable nozzle of the inflatable shaft?

Hello, how to distinguish the inflatable nozzle of the inflatable shaft depends on whether the convex point type (type A) is the tip in the middle of the top; The concave point type (type B) is concave at the top. The specification of the gas nozzle is G 1/4 thread; G3/8 thread; G 1/8 thread; M 14* 1.5 thread; M 14* 1 thread, name of gas nozzle inflation shaft: G 1/4-A, G 1/8-B, M 14* 1.5-A, m.

The working principle of the pneumatic shaft of crown block is to adjust the torque of each sliding sleeve on the shaft through the pressing force of the pressing spring adjusting mechanism at both ends of the shaft. Because of its structure, the pressure is mechanically transmitted from both ends of the shaft, the stress of each sliding sleeve is uneven, the torsion of each sliding sleeve can not be fully adjusted with the tension change required by the material cutting change, and the relative sliding between sliding sleeves is not good, which is easy to cause uneven winding, broken strips and loose winding, resulting in material loss. The winding speed is low. When adjusting the pressure, it is necessary to stop the machine for adjustment, which affects the work efficiency. A common inflatable shaft consists of an inflatable shaft and a strip-shaped expansion tile.
