Arc transition is respectively set in each corner angle of annular groove, and the annular air-pocket to match with annular groove is arranged in annular groove,
The positioning mechanism that annular air-pocket is 2 or more by quantity is arranged in annular groove, and quantity is that 2 or more positioning mechanisms are equal
On the even circumference being distributed in centered on the annular center line of annular groove, positioning mechanism includes bind ring A, bind ring B and bullet
Property band, bind ring A is fixedly installed on groove slot bottom, bind ring B is fixedly installed on annular air-pocket, one end of elastic webbing passes through bind
The mode of connection is fixedly connected with bind ring A, and the other end of elastic webbing is fixedly connected with bind ring B in such a way that bind connects.
Preferably, the annular center line of the annular air-pocket and the annular center line of annular groove are on same straight line.
Preferably, it is described fixed setting for by bolted connection, the mode of bonding connection, bind connection mode
And/or the mode of clamping connection is fixedly installed.
The beneficial effects of the utility model are: 1, mechanical seal uses the usage mode of 3 linear sealings, sealing ring is in sealing
Using 3 annular line contact sealings, compared with the prior art in face contact sealing, the contact position of line can facilitate generation more
Big sealed pressure is avoided that sealed pressure caused by face contact is dispersed, and then realizes the promotion of sealing effect.2, using simple
3 linear sealings that structure is formed, not only make structure most simplified, but also it is maximum using effect that each structure can be made to play, and reaches
To preferable using effect.3, product service life can be increased.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the portion the A enlarged drawing of Fig. 1.
Specific embodiment:
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；In order to better illustrate this embodiment, attached
Scheme certain components to have omission, zoom in or out, does not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.
Referring to each figure, a kind of mechanical sealing member, including sealing ring 1, sealing ring 1 include medial surface and lower end surface, sealing ring 1
Medial surface surround the channel 2 for being set on axis, which further includes the annular groove to match with sealing ring 1
3, annular groove 3 is arranged in the lower end surface of annular air-pocket 4 and positioning mechanism (not shown), U-shaped sealing ring 1, annular groove 3
For the center line of annular center line and sealing ring 1 on same straight line, annular groove 3 includes groove side 5 and groove slot bottom 6,
The groove side 5 of annular groove 3 and groove slot bottom 6 are respectively arcwall face, each corner angle difference of sealing ring 1 and annular groove 3
Arc transition, the annular air-pocket 4 that setting matches with annular groove 3 in annular groove 3 are set, and annular air-pocket 4 is 2 by quantity
A above positioning mechanism is arranged in annular groove 3, and quantity is that 2 or more positioning mechanisms are evenly distributed on annular groove
On circumference centered on 3 annular center line, positioning mechanism includes bind ring A7, bind ring B8 and elastic webbing 9, groove slot bottom 6
Bind ring B8, the side that one end of elastic webbing 9 is connected by bind are fixedly installed on annular air-pocket 4 by upper fixed setting bind ring A7
Formula is fixedly connected with bind ring A7, and the other end of elastic webbing 9 is fixedly connected with bind ring B8 in such a way that bind connects.
Preferably, the annular center line of annular air-pocket 4 and the annular center line of annular groove 3 are on same straight line.
Preferably, be fixedly installed for by bolted connection, the mode of bonding connection, bind connection mode and/
Or the mode of clamping connection is fixedly installed.
When in use:
1, mechanical seal uses the usage mode of 3 linear sealings, and sealing ring 1 is close using 3 annular line contacts in sealing
Envelope, compared with the prior art in face contact sealing, the contact position of line, which can facilitate, generates bigger sealed pressure, is avoided that face
The dispersion of sealed pressure caused by contact, and then realize the promotion of sealing effect.
2,3 linear sealings formed using simple structure, not only make structure most simplified, but also each structure can be made to send out
Maximum is waved using effect, reaches preferable using effect.
3, the groove side 5 of annular groove 3 and groove slot bottom 6 are respectively arcwall face, sealing ring 1 and annular groove 3 it is each
Arc transition, the annular air-pocket 4 that setting matches with annular groove 3 in annular groove 3, using such knot is respectively set in a corner angle
On the one hand structure makes 4 bottom of annular air-pocket form a sealing when 1 upper surface of sealing ring receives the pressure of sealing installation
Ring shaped contact seal line A, arc transition is respectively set in each corner angle of another aspect annular groove 3, and to form ring shaped contact again close
Sealing ring 1 can also be guaranteed even 1 upper surface of sealing ring receives excessive pressure by sealing line B and ring shaped contact seal line C
Lower end surface is sealed by ring shaped contact seal line A, ring shaped contact seal line B and ring shaped contact seal line C always, is avoided
The dispersion of sealed pressure caused by face contact, and then realize the promotion of sealing effect；Positioning mechanism uses bind ring A7, bind ring B8
