Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in the figure, a kind of swivel joint with elasticity encapsulate metal corrugated expension joint structure, be made up of holding part and rotation section two-part, described holding part comprises: water inlet cover 1, the first seal ring 2, the first ceramic-seal ring 3, the first circlip 4, rotation section comprise:
the second circlip 5, the second ceramic-seal ring 6, sealing head 7, the second seal ring 8, metal bellows 9, colloid shell 10, colloid 11, one-way valve 12, it is characterized in that: described the first seal ring 2 is arranged in one end inner-diameter end face seal groove of water lid 1, the first ceramic-seal ring 3 is arranged on into endoporus the inside, one end one end face of water lid 1 and contacts sealing with the first seal ring 2, the other end contacts with the first circlip 4 being arranged on in the internal diameter groove of one end of water lid 1, and by the first circlip 4, it is spacingly formed to holding part with water inlet lid
the second seal ring 8be arranged in one end inner-diameter end face seal groove of sealing head 7, the second ceramic-seal ring 6 is arranged on the endoporus the inside, one end of sealing head 7, one end face contacts sealing with the second seal ring 8, the other end contacts with the second circlip 5 being arranged in the internal diameter groove of one end of sealing head 7, and spacing to it by the second circlip 5, the other end of sealing head 7 and metal bellows 9 one end welding, metal bellows 9 arranges the internal diameter with colloid shell 10, the other end of metal bellows 9 and colloid shell 10 weld, the local internal diameter the inside of inserting colloid shell 10 of axle external diameter of sealing head 7, one-way valve 12 is arranged in the end-face helical hole of colloid shell 10, colloid 11 in the time of liquid state by being filled with by one-way valve 12 in the space between the internal diameter of colloid shell 1 and the external diameter of metal bellows, rotating section through sulfuration sizing composition, in use holding part the first sealed ceramic ring 3 and the second sealed ceramic ring 6 rubbing contact sealings of rotation section.
This swivel joint adopts the coated one deck elastic gel elastic element as compensation of metal bellows outer surface portion, and this rubber adhesive not only has elastic performance, can also improve metal bellows withstand voltage properties.Because having fine damping capaicty, rubber itself is particularly suitable for the king-sized operating mode of roller vibration, effectively ensure the contact quality that fits tightly of two friction sealed, can also effectively alleviate the metal fatigue phenomenon of metal bellows because caused by vibrations, this colloid can select different colloids according to the difference of Environmental Conditions, thereby the elastomer that can colloid be sulfided into different hardness according to different working condition pressures obtains different elasticity dynamics, thereby do not need the way that increases the external diameter of swivel joint or reduce internal diameter just can adapt to the requirement of higher pressure medium, two ceramic-seal rings change dull surface to grinding friction sealed into by minute surface, effectively alleviate the two friction sealed negative-pressure adsorption power while sealing of grinding of facing, reduce the torsional moment of bellows in initial start stage, make swivel joint rotation more flexible.This encapsulate metal corrugated expension joint is not only applicable to this type of swivel joint, equally can be applied to other the swivel joint in machinery industry standard yet.200 revs/min of applicable rotating speeds of the present utility model, maximum pressure 2.5MPa, 180 DEG C of temperature, the working condition of frequent vibration, suitable water, wet goods medium.
