JOINT FOR LIGHT ALLOY TANK Code: 0785PHD813854

SCHEDA 1150_doppio_snodo-rev 09-2011

Description

The joint for suction and delivery is located in the middle of the fifth wheel in correspondence with the rotation axle. The assembly of the fifth wheel with double passage swivel joint is used in aircraft refuellers made up of tractors and semi-trailers configured with the fuelling unit located behind the cabin and the fuelling platform situated at the rear of the vehicle. The assembly fifth wheel-joint allows to link the trailer to the tractor for towing and linking the suction pipe between the tank and the unit, and the platform feeding during fuelling operation.

Technical features

The joint has 4 features:

Upper manifold inside the 304 stainless steel tank
Welding flange in stainless steel or light alloy (depending on the tank material)
swivel joint made of light alloy
External lower manifold in 304 stainless steel

 

The main element is the swivel joint made up of aligned tubes which are coaxially provided with reciprocal reversing movement; it has 2 double-manifolded bodies with an extremity flange each, and a diameter each which enables them to be fit one into the other after inserting 2 graphited steel bushes where it has been interposed a sphere rim between them as a bushing. This rim allows the rotation between the part linked to the fixed pie and the reversing one. The swivel joint is such to guarantee a high level of reliability, mostly as far as the ability to keep all the time in perfect axes the linked parts of the tube.
