Description
Technical field
The utility model belongs to technical field of mechanical, is related to a kind of quiet group of full sulfuration type of mechanical seal.
Background technique
Mechanical sealing member is widely used in the equipment such as pump, compressor and Mixing Machine.It is to separate rotary part (such as that it, which is acted on,
Axis) and static structural cavity body between leak path, prevent the intracorporal hazardous medium of chamber from leaking into the external world.Mechanical sealing member is logical
Often it is made of the dynamic component being fixed on axis with the quiet component for being fixed on cavity.
The quiet group of sealing of Single spring rubber bellows is a kind of common mechanical seal structure, moves component by stationary ring, rubber
Bellows, pressure elements spring and hardware composition；Its dynamic component is relatively easy, by a rotating ring and rubber sealing element
It constitutes.Rotating ring and stationary ring are the friction pairs of a pair of of high-flatness, constitute sealing surface under pressure elements effect.The two relatively rotates
When gap in micron dimension, can effectively prevent internal flow from revealing from sealing surface.The spring of quiet component is compressed when installation, from
And provide the normal pressure on sealing surface.The normal pressure must offset thrust caused by sealing internal fluid pressure and just be able to maintain sealing
Face closure.If the design work pressure of sealing is very high, elastic element will be very high in the normal pressure of working depth, thus to dynamic
Stationary ring brings very high moment of friction.
In traditional rubber bellows mechanical seal, the moment of friction of stationary ring is transferred to by rubber bellows and stationary seat
Cavity.In the case where not having tight loop, stationary ring and stationary seat and rubber bellows be easy to cause sliding, are easy to gall rubber corrugated
Pipe causes sealing initial failure.
In conclusion the utility model designs quiet group of full sulfuration type of a kind of service life that can effectively improve sealing element
Mechanical seal.
Summary of the invention
The purpose of this utility model is the presence of the above problem in view of the prior art, and proposing a kind of can effectively improve sealing
Quiet group of full sulfuration type of mechanical seal of the service life of part.
The purpose of this utility model can be realized by the following technical scheme: a kind of mechanical seal of quiet group of full sulfuration type,
Including axis, sealing ring, vulcanized rubber part, the vulcanized rubber part is set in outside axis and is set as beloid structure, described
It is set as step structure in the middle part of vulcanized rubber part, the sealing ring is embedded one end relatively narrow in vulcanized rubber part, and sealing ring
It is set in outside axis, installation cavity is equipped in the vulcanized rubber part, the axis passes through installation cavity, is provided with and is set in installation cavity
Spring outside axis, the spring are set as the structure that width is incremental from front to back, stationary seat, institute are equipped with outside vulcanized rubber part
Stationary seat is stated to be fitted tightly on vulcanized rubber part middle section to back segment outer wall, the vulcanized rubber part and stationary seat, sealing ring it
Between pass through vulcanization connect.
The spring one end offsets with vulcanized rubber part inner wall as a further improvement of the utility model, and the other end is logical
Spring base is crossed to be mounted in installation cavity.
Based on the above-mentioned technical proposal, the utility model embodiment at least can produce following technical effect: this mechanical seal
Each component is combined by the mode vulcanized in the sealing structure being related to, and produce relative sliding each component will not, is reduced close
Sealing assembly, the service life for increasing sealing element reduce cost, utilize in rubber parts tail portion and stationary seat and with sealing ring junction
The mode of vulcanization connects, and vulcanized rubber replaces rubber bellows, and stationary seat, which refills, to be fitted in cavity, and spring and vulcanized rubber are utilized
Elasticity compensate, each component becomes rigid biography from pervious interference overall viewing range after vulcanization, vulcanized rubber is opposite
It is significantly improved in General Purpose Rubber abrasion resistance, heat resistance etc. tool, expands the application range of machine envelope, raising machine envelope makes
Use the service life.
Detailed description of the invention
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing, in which:
Fig. 1 is the structural schematic diagram of one preferred embodiment of the utility model.
In figure, 100, axis；200, sealing ring；300, vulcanized rubber part；400, stationary seat；500, spring；600, spring base.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
Below with reference to Fig. 1, technical scheme provided by the present invention will be described in more detail.
As shown in Figure 1, the mechanical seal of this complete quiet group of sulfuration type includes axis 100, sealing ring 200, vulcanized rubber part 300,
The vulcanized rubber part 300 is set in outside axis 100 and is set as beloid structure, sets in the middle part of the vulcanized rubber part 300
It is set to step structure, the sealing ring 200 is embedded one end relatively narrow in vulcanized rubber part 300, and sealing ring 200 is set in axis
Outside 100, installation cavity is equipped in the vulcanized rubber part 300, the axis 100 passes through installation cavity, is provided with and is arranged in installation cavity
