Air quick coupler, substantially used for air pipeline, air tool accessories. Corresponding to its use, there are a variety of body accouterments, sizes, and installation shapes.
There are colorful operation scripts of curvaceous quick joints, which can generally be divided into pipe inner periphery sealing and pipe external periphery sealing, inner thread, and external thread, etc. Air pressure is used to drive the sealing ring to expand or the claws to grasp, so as to achieve the effect of sealing connection. There are further tube types, flanged tubes, formed tubes, burned tubes, abbey tubes,etc. can be snappily sealed with curvaceous quick connectors. Through these three introductory points, the joint and selection can be judged.
structure type
The so- called structural form is the appearance form of the common formed in consideration of the pipeline direction, inflow distribution, and connection. For illustration, T- type EPE, Y- type EPY, and straight- through EPC are each defined from the appearance and structure.
The external or inner periphery of the trachea
On the base of attesting the structural form, we need to confirm the external periphery or inner periphery of the cannula. The general quick connector is for quick intubation of the trachea, so it's necessary to confirm the external periphery or inner periphery of the trachea. Generally two look quick connector blue top number and caliper card trachea OD.
thread
For threaded joints, it's necessary to confirm the thread specifications. There are numerous thread specifications. The common bones are R thread ( also called PT thread) and G thread, and R thread is the most common.
