Abstract
The invention discloses a kind of inflation pressure maintainings of tank body to seal axis, the sealing axis is made of mandrel, sealing shroud, this special envelope, tracheae, nut, outer top cover, rubber ring, inner top cover and tank body, it is sealed axis and is achieved the purpose that sealing using rubber ring compressive deformation, and is inflated pressure maintaining by rotatory sealing.Regular rubber ring between the outer top cover and inner top cover contacts with tank body port inner tight by rotation trapezoidal nut compressive deformation, reaches sealing purpose；Rotatable interface is made of sealing shroud, this spy's envelope and air pipe interface, is installed on mandrel, and when mandrel and tank body rotate, rotatable interface is filled with gas and preserves value static, reaches inflation pressure maintaining purpose.Sealing sealing effect provided by the present invention is good, suitable for on the various tank bodies that have higher requirements of sealing.
Description
Technical field
The invention belongs to the installation shaft sealers of tank body, and in particular to a kind of tank body inflation pressure maintaining sealing axis.
Background technique
In order to meet the transport needs of various liquid and sewage, occur various tank body and tank car at present, tradition
Tank body sealing be it is equidistant along one week on Cap for tin body uniformly fastened with bolt, sealing ring is compressed, still, even if one
People's operation, using diagonal fastening method, and uses torque spanner as tool, it is also not possible to twist into all bolt pretightenings
Equally, to cause sealing ring since stress has successively, pressing force is uneven, and deformation is also different, therefore seal degree is limited
's.In view of the above-mentioned problems, the prior art also uses bull bolt while the bolt fastening of fastening is mechanical, but, each bolt by
Different in the precision of processing, it, although being greatly improved than manually fastening bolt, is not most scientific that fastening resistance is different yet
Design.
Sealing structure between shaft or installation axle and tank body has the following deficiencies: that (1) pressure inside the tank is big, according to filler
Sealing, filler are easy failure under the erosion of silt or other articles, and replacement frequency is high, and sealing effect is bad；(2) according to machine
Envelope be mounted in tank body, although sealing effect can be improved, once seal failure, dismounting maintenance it is very inconvenient, maintenance at
This height.
Summary of the invention
Goal of the invention: in view of the above shortcomings of the prior art, the present invention provides a kind of tank body inflation pressure maintaining sealing axis, this is close
Envelope sealing effect is good and maintenance is facilitated to replace.
Technical solution: a kind of tank body inflation pressure maintaining sealing axis, the sealing axis include mandrel, sealing shroud, this spy's envelope, gas
Pipe, nut, outer top cover, rubber ring, inner top cover and tank body composition, the mandrel perforation tank body are installed, are set inside the mandrel
There is tracheae, tracheae one end is equipped with rotatable interface, is equipped with rubber ring between the outer top cover inner top cover, compresses and become by rotating nuts
Shape contacts sealing with tank body port inner tight, and the rotatable interface is made of sealing shroud, this spy's envelope and air pipe interface, is installed on
On mandrel, when the mandrel and tank body rotate, rotatable interface is filled with gas and remain stationary state.
Further, this described spy's envelope is arranged inside sealing shroud, and is located at the two sides of air pipe interface, the sealing shroud
Wrap up the two sides air pipe interface up and down of tracheae；
Further, the nut is trapezoidal nut, is tightened by the screw thread being arranged on the outside of mandrel to tank body side；
Further, the inner top cover is located at and protrudes on the mandrel of tank interior, and is fixed on mandrel；
Further, the contact surface of the mandrel and tracheae is equipped with sealant, and the sealant includes air cushion or rubber
Rubber mat；
Further, the contact position of the mandrel and tank body two sides is equipped with identical sealing device, and sealing axis is pair
Claim structure.
The utility model has the advantages that compared with prior art, the present invention its significant effect is: one aspect of the present invention utilizes rubber ring
Compressive deformation is inflated pressure maintaining by rotatory sealing to achieve the purpose that sealing, including by the way of rotation and inflation
It realizes sealing, further increases sealing effect；On the other hand, the present invention is only needed replacing according to the different articles stored in tank body
Or the different contact point sealing ring materials of replacement, it is repaired while convenient and practical easy to change.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is the sealed structural schematic diagram of sealing axis of the present invention.
Specific embodiment
In order to which technical solution disclosed by the invention is described in detail, with reference to the accompanying drawings of the specification and specific embodiment do into
The elaboration of one step.
As depicted in figs. 1 and 2, a kind of tank body inflation pressure maintaining seals axis, the sealing axis mainly by mandrel 1, sealing shroud 2, this
Spy's envelope 3, tracheae 4, nut 5, outer top cover 6, rubber ring 7, inner top cover 8 and tank body 9 form, and mandrel 1 penetrates through tank body 9 and installs, mandrel 1
Inside is equipped with tracheae 4, and 4 one end of tracheae is equipped with rotatable interface, rubber ring 7 is equipped between 6 inner top cover 8 of outer top cover, by rotating spiral shell
Female 5 compressive deformations contact sealing with 9 port inner tight of tank body, and rotatable interface is by sealing shroud 2, this spy's envelope 3 and air pipe interface group
At being installed on mandrel 1, when the mandrel 1 is rotated with tank body 9, rotatable interface is filled with gas and remain stationary state.
Specifically, a kind of tank body inflation pressure maintaining sealing axis provided by the invention is initially mounted on tank body 9 when using
On, tank body 9 can make to penetrate through installation settings, also include that tank body 9 is divided into two and its above chamber, sealing axis is arranged not
In same chamber or gap.It seals and is equipped with tracheae 4 inside the mandrel 1 of axis, and the both ends of mandrel 1 are set, fixed tracheae 4 is installed
Afterwards, its sealing device is set.Sealing device include sealing shroud 2, this spy envelope 3, nut 5, outer top cover 6, rubber ring 7, inner top cover 8,
Inner top cover 8 is fixed on the inside of tank body 9, including carries out preventing from being displaced by the way that fixed baffle is arranged to the left, makes it in pressure
Under be adjacent to the inside of tank body 9, on the outside mandrel 1 of tank body 9, rubber ring 7 is bonded tank body 9 and is arranged, and right side is outer top cover
6, outer top cover 6 cooperates the inner top cover 8 inside tank body 9 to be gradually adjacent to sealing under the rotation of nut 5, and rubber ring 7 returns under stress
Deformation is generated, sealing is promoted.The interface of tracheae 4 is constituted rotatable interface, and is mounted on by sealing shroud 2, this spy's 3 air pipe interface of envelope
On mandrel 1, when mandrel 1 and the rotation of tank body 9, rotatable interface is filled with gas and remain stationary, and reaches inflation pressure maintaining purpose.
Mandrel 1 in the present invention realizes the first seal structures using 7 compressive deformation of rubber ring, by rotatory sealing into
Further sealing is realized in row inflation pressure maintaining, greatly provides the sealing effect between tank body 9 and mandrel 1 or shaft branch.
