Embodiment
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Reference picture 1 come illustrate the present invention mechanical seal overall structure.Fig. 1 represents the machine of the specific embodiment of the invention
Tool is sealed in the schematic cross sectional views for assembling state after rotary shaft 110.In Fig. 1, the section of mechanical seal is to include forming
The section of the central axis (consistent with the central shaft of rotary shaft) of each annular element of mechanical seal, mainly matches somebody with somebody including end face seal
The axle sleeve 80 that the rotating ring 50 of conjunction coordinates with stationary ring 10 and with rotating ring 50 and the stationary seat 20 with the cooperation of stationary ring 10.
Stationary ring 10 as shown in Figure 1 and the rotating ring 50, axle sleeve 80 and the elastic device that coordinate with the sealing of stationary ring 10 are placed in
Inside stationary seat 20, so that integral seal structure compact volume reduces.4 are uniformly offered on the periphery of stationary seat 20
Fabrication hole 40.Fabrication hole 40 can facilitate the installation and dismounting of seal, can be noted in addition from fabrication hole 40 into cooling chamber 120
Enter cooling medium, to each part cooling in seal so that seal working stability life.
With reference to Fig. 1,2,3, the described outer face of stationary ring 10 is bonded with the inner face of stationary seat 20, and stationary ring 10 is bonded end face and opened up
There are 6 screwed holes 90, correspond to therewith, the screwed hole 90 of 6 equivalent specifications, two groups of central shafts of screwed hole 90 are offered on stationary seat
Unanimously, during installation, stationary ring 10 aligns with the screwed hole 90 of stationary seat 20 to be fixed with bolt connection.So cause work when stationary ring 10 by
Do not moved axially to during axial force, end face is fitted close.The outer circumference surface of stationary ring 10 is additionally provided with groove and matched somebody with somebody with stationary seat 20
Close to form and accommodate the composition axial seal of o shapes circle 30.Sealing so between stationary ring 10 and stationary seat 20 can be achieved.Such as Fig. 1 institutes
Show, axle sleeve 80 is the smaller and larger two parts pipeline section of diameter, and diameter fluted is matched somebody with somebody with rotating ring 50 compared with being set on the tube wall of segment
Close to form and accommodate the composition axial seal of o shapes circle 130.Sealing so between rotating ring 50 and axle sleeve 80 can be achieved.
With reference to Fig. 1,4,6, fluted formed with the cooperation of axle 110 is set to accommodate o shapes on the inner tubal wall face of cylinder of axle sleeve 80
Circle 140 forms axial seal, and the sealing between such axle sleeve 80 and axle 110 can be achieved.In addition, it is relatively large in diameter portion on axle sleeve 80
It is in charge of on the cylinder end face of section and uniformly offers 4 spring eyes 150, the side end face of rotating ring 50 1 is bonded with the end face of stationary ring 10, another
End face is provided with air ring 60.Spring 70 is placed with each spring eye 150, it is another that the one end of spring 70 props up the bottom of spring eye 150
One end props up air ring 60, air ring 60 cause spring 70 act on the end face of rotating ring 50 balancing force it is uniform, such rotating ring 59 with
Stationary ring 10 is brought into close contact, and the sealing between rotating ring 50 and stationary ring 10 can be achieved.Used spring 70 be by spring steel 70A and
Peripheral hardware covered plastics layer 70B is formed, and spring steel 70A is stainless steel, has resistance to corrosion.
4 motion thread holes 100 are evenly arranged with the end face outside of axle sleeve 80 as shown in Figure 5, pass through motion thread hole
100 connecting shafts 110 so that rotating ring 50 can be with the synchronous axial system of axle 110.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
