Description
[technical field]
The utility model is related to the accessory device technical field of pipeline, specifically a kind of connecing for metal bellows
Head device.
[background technology]
Metal bellows is that a kind of external form is the tubing of the wave sample of rule, is mainly used in irregular turning, stretches, absorbs
The thermal deformation of pipeline, the company for being not easy to make pipeline and the connection of pipeline and pipeline and equipment of the occasion that fixed elbow is installed
Connect.
Traditional metal bellows is connected usually by bellows-welding on jointing, when using welding point,
The problem of easily there is melting in welding process because the wall thickness of metal bellows is relatively thin, it is undesirable to result in sealing effectiveness,
And easily potential safety hazard is caused in use.
China's number of patent application：CN201520316107.7 discloses a kind of piecing devices for gas piping, ripple
It is sequentially provided with outer tooth joint, rubber ring and nut on pipe, it is easy to assembly and coordinate firm, but this soft sealing structure is passing through
After prolonged use, easily there is aging in rubber ring, thus influence product it is normal, effectively use, be likely to result in leakage thing
Therefore generation.
[utility model content]
The purpose of this utility model is that solve the deficiencies in the prior art fills there is provided a kind of joint for metal bellows
Put, the hard sealing structure constituted using outer tooth connector, locking nut, locating aperture ring and retainer ring, ensure that has for a long time
Use to effect.
To achieve these goals, a kind of piecing devices for metal bellows, including outer tooth connector, locking are designed
Nut, locating aperture ring, retainer ring and corrugated stainless steel tubing, corrugated stainless steel tubing are provided with trough and crest, stainless steel ripple
Pipe is coated with plastic wraps layer, and corrugated stainless steel tubing is exposed close to joint one end, it is characterised in that：
If locating aperture ring constitutes annular shape by dry plate splicing, locating aperture inwall is provided with some grooves and stainless steel ripple
The trough and crest that pipe is provided with are engaged, and locating aperture ring lateral ends are provided with the edge of outwardly convex, and locating aperture ring is set
Corrugated stainless steel tubing is placed in close to the exposed one end of joint；
Retainer ring section is stepped, is that big ring, inner side are small ring on the outside of retainer ring, the outer shroud of retainer ring is set in positioning
Outside split ring；
Locking nut is arranged on the outside of retainer ring, and the big ring of retainer ring and small ring junction are stuck in locking nut bottom；
Outer tooth connector lateral ends are provided with outer tooth connection screw thread, and inner opposite end is provided with the screw thread being connected with locking nut,
The inner chamber of outer tooth connector inner opposite end coordinates provided with raised sealing ring with the edge that locating aperture ring convex rise.
Described outer tooth connector, locking nut, locating aperture ring and retainer ring is made of metal.
The piecing devices of described metal bellows use metal hard-sealing.
Compared with the existing technology, construction is novel, combining structure simple possible for the utility model, it is easy to install with dismantling, its
Advantage is：
1. the splicing of piecing devices and easy removal and reliable；
2. using hard sealing structure, can effectively and safely it use for a long time；
3. coordinating firm, manufacturing cost is low, it is adaptable to various fields of employment, safe and reliable.
