Function of quick coupling devices can be described as coupling a tube to its rigid end piece. It comprises of two parts, i.e., male tubular part attached to the tube end and female tubular part fitted to the rigid end pieces for being coupled properly. The female part has been featured with stepped bore wherein huge diameter portion is included which is further capable of receiving male part’s shoulder beyond an axial latch. Male part can be described as an elongated portion which has cylindrical surface fitted outside with retention projection. It has been designed in such a manner so that connection can be established between the tube and the male part.

Two stages of initial coupling

Initial coupling gets successfully accomplished in two stages

I) Tube needs to get fitted on the male part which requires strong engagement form so that concrete clamping gets done such that establishment of connection remains leak proof.
II) The male section needs to get inserted inside the female section such that shoulder ...
... of the male one has passed by the axial latch of the female.

Between the two parts, disposal of o-rings takes places so that the connection in between could be sealed. Then decoupling section comes in wherein male part needs to get detached from the female part by disconnecting the tube by acting on the axial latch. This type of device supports frequent connection and disconnection activities that too without damaging mechanical quality of the quick couplings formed. Special tooling and handling is required in case of initial coupling for engaging the tube on the male portion.

Overview of quick release coupling

Quick release couplings hold a crucial role to perform in the application field as it indicates the interface prevails between the power source and the hydraulic attachment. So you can easily analyze that performance of quick release coupling have strong impact on the performance of the attachment. Higher energy shall be received by the attachment with better performance of the coupling from the machine for the execution of in hand job. This type of couplings is preferred in machinery construction as it belongs to the series of flat face. It has been featured with perfect flat surface of the shut-off valves and the mating surfaces. Basically this design has been benefitted with zero spillage or air inclusion while the process of connection and disconnection continues. It is environmentally sensible and allows you to save a lot along with which easy cleaning of the matting surface is also facilitated.

Thus, you have acquired basic idea about couplings and its features, so now allow your knowledge to guide you through selection process of the product suiting your requirement.
