Please refer to Fig.1-3, a kind of sealing ring that leakproofness effect is strong, including the first pad 1, the top of the first pad 1 with
Bottom offers slot hole 2, and two slot holes 2, with the substantially symmetrical about its central axis of 1 section of the first pad, the side of the first pad 1 opens up
There is an elongated slot 3, the quantity of elongated slot 3 is two, and two elongated slots 3 are in same level, by being two by the quantity of elongated slot 3,
So that the first pad 1 by vertical direction pressure when, the compression of volume can be carried out so that both sides are compressed evenly, the
The top of one pad 1 is installed with the second pad 4, and the shape of the second pad 4 is V-shaped, and the elasticity of the second pad 4 compared with
It is good, by the V-shape groove of formation, a special seal area is formed, even if the second pad 4 is impaired by reciprocating friction, on
The effect that special seal area still functions as sealing is stated, to substantially increase the sealing performance of entire sealing ring, the second pad 4
Upper equal fixing sleeve is equipped with the first protective layer 5, and the equal fixing sleeve of top and bottom of the first pad 1 is equipped with the second protective layer 6, and first protects
Sheath 5 and the second protective layer 6 are nitrile rubber protective layer, and the thickness value of the first protective layer 5 and the second protective layer 6 is equal,
By the way that the first protective layer 5 and the second protective layer 6 are set as nitrile rubber protective layer, the wearability of nitrile rubber is utilized so that
The wearability enhancing of entire sealing ring has achieved the effect that the entire sealing ring of protection, the top of the second protective layer 6 and the first protection
The bottom of layer 5 is fixedly connected, and the top and bottom of 6 side of the second protective layer is installed with boss 7, and boss 7 is located at length
The quantity of the both sides of slot 3, boss 7 is four, and boss 7 every groups two, and two groups of boss 7 are with the front of the first pad 1 at axle center
Symmetrical, fixing sleeve is equipped with frictional layer 8 on the first protective layer 5, and frictional layer 8 is skid resistant course, and the shape of frictional layer 8 is V-shaped,
The movement for preventing the second pad 4 further improves the stability of entire sealing ring, supporter 9, support is equipped in slot hole 2
Connector 10 is installed on body 9, the quantity of connector 10 is five, and five 10 annulars of connector are evenly distributed in branch
On support body 9, pass through the setting of five connectors 10 so that the external force that supporter 9 is subject to is uniform, so that the first pad 1 exists
It is deformed upon when by external force, due to the first pad 1 is avoided to cause its damage, connector 10 and the first pad 1 solid because stress is excessive
Fixed connection.
In conclusion the sealing ring that the leakproofness effect is strong, passes through the second pad 4, the first protective layer 5 and frictional layer 8
Cooperation, and the shape of the second pad 4, the first protective layer 5 and frictional layer 8 is set as V-shaped, form a special sealing
Area, even if to be repeatedly subjected to friction impaired for frictional layer 8, when the above-mentioned seal area that is formed by still functions as the effect of sealing, even if working as
After frictional layer 8 is worn badly completely, and the first protective layer 5 makes for nitrile rubber protective layer under the action of the first protective layer 5
It obtains the second pad 4 still to play a role, be not worn to play the second pad 4 of protection so that sealing ring is able to permanent
It uses, to extend the service life of sealing ring；The strong sealing ring of the leakproofness effect passes through elongated slot 3, slot hole 2 and connection
The cooperation of body 10, when the first pad 1 is squeezed by the gap between elongated slot 3, slot hole 2 and connector 10, along with length
The effect of slot 3 so that 1 deformation of the first pad so that the first pad 1 can effectively offset its power being subject to, in high pressure conditions
