Abstract
The self-repairing static sealing ring comprises a sealing ring main body, wherein the sealing ring main body is integrally in an annular hollow form, and a repairing injection agent is filled in the sealing ring main body; and the inner wall of the sealing ring main body is provided with an injection cavity, and an injection valve is arranged in the injection cavity. The utility model discloses simple structure, convenient to use, the suitability is strong and easy to maintain, restoration. The material of the sealing ring is different from that of common sealing, and when the synthetic natural rubber is adopted, the meridian is designed by utilizing high-strength glass fiber on the inner wall and the outer wall of the sealing ring, so that the sealing ring has the advantages of large elasticity, good wear resistance, long service life, good buffering performance, large bearing capacity, difficulty in puncture and the like. On the other hand, the repairing injection agent in the sealing ring is injected by adopting anaerobic sealing colloid, once leakage occurs under the action of installation or equipment impact, the sealant is firstly leaked along a damaged point, the colloid is rapidly solidified after contacting air, the leakage point is blocked, the sealing surface is re-run, and the autonomous repairing is realized.
Description
Technical Field
The utility model relates to a mechanical seal field especially relates to a selfreparing static seal circle.
Background
The existing industry also applies a large number of O-shaped sealing rings, most of the sealing rings are used for static contact surfaces, such as oil cylinder pistons, inner walls and equipment end surfaces, and through field investigation, leakage caused by the damage of the sealing rings is mainly caused by the following two aspects, namely, firstly, because the sealing installation parts are all non-visible surfaces and the sealing has the characteristic of extending out of a sealing groove to extrude and seal, the sealing rings are extremely easy to damage and cause leakage in the installation process; secondly, the seal is subjected to extrusion plastic deformation in the end face extrusion process to lose the sealing effect, so that leakage is caused; at present, most of the seals are made of nitrile rubber or fluororubber, and along with the prolonging of the service life of the seals or special service conditions, the aging of rubber materials causes the failure of seal rings or the occurrence of permanent plastic deformation, and most of the seals are invisible surfaces of equipment, so that the replacement or the maintenance are extremely troublesome, and most of the seals need to be repaired greatly or the end covers are disassembled to maintain, thereby causing production delay.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art weak point, provide a can be independently prosthetic special sealing washer, this sealing washer appearance and mounting dimension are unanimous with ordinary oil blanket, can replace ordinary rubber seal completely, and the commonality is high.
The self-repairing static sealing ring comprises a sealing ring main body, wherein the sealing ring main body is integrally in an annular hollow form, and a repairing injection agent is filled in the sealing ring main body.
And the injection cavity is arranged on the outer wall of the sealing ring main body. An injection valve is arranged in the injection cavity.
Furthermore, the main body of the sealing ring is made of synthetic natural rubber, and the inner wall and the outer wall of the sealing ring are provided with meridians by high-strength glass fibers.
Further, the repair injection is an anaerobic repair injection.
Furthermore, the agent injection valve is in a liquid return prevention heart valve form, and the inner heart valve of the agent injection valve can effectively prevent liquid from flowing back.
When the utility model is used, the special injection pump injects the anaerobic repairing injection through the injection cavity. This annotates agent has two aspects effects, can play the liquid spring effect firstly, can adjust the sealing washer thickness according to the seal groove size of difference, makes the sealing washer have sealed elastic sealing's performance. Compared with the common sealing ring, the liquid spring can increase the resistance of sealing plastic deformation and always keep the sealing surface under the action of pressure sealing. On the other hand, the sealed anaerobic repairing injection agent is injected by adopting anaerobic sealing colloid, once leakage occurs under the action of installation or equipment impact, the sealant firstly leaks along a damaged point, the colloid is rapidly solidified after contacting air, the leakage point is blocked, the sealing surface is stroked again, and the autonomous repairing is realized.
The utility model has the advantages that: the utility model discloses simple structure, convenient to use, the suitability is strong and easy to maintain, restoration. The radial sealing structure has the advantages of large elasticity, good wear resistance, long service life of sealing, good buffer performance, large bearing capacity, difficult puncture and the like compared with the common sealing ring. On the other hand, the repairing injection agent in the sealing ring is injected by adopting anaerobic sealing colloid, once leakage occurs under the action of installation or equipment impact, the sealant is firstly leaked along a damaged point, the colloid is rapidly solidified after contacting air, the leakage point is blocked, the sealing surface is re-run, and the autonomous repairing is realized.

the objects, features and advantages of the present invention will be further described with reference to the accompanying drawings.
Detailed Description
Referring to fig. 1 and 2, a selfreparing static seal circle include sealing washer main part 1, sealing washer main part 1 wholly is annular cavity form, and its inside packing has the restoration to annotate the agent.
And an injection cavity 2 is arranged on the outer wall of the sealing ring main body 1. An injection valve 4 is arranged in the injection cavity 2.
Further, the seal ring main body 1 is made of synthetic natural rubber, and the inner wall and the outer wall of the seal ring are provided with meridians by high-strength glass fibers.
further, the repair injection is an anaerobic repair injection 3.
Furthermore, the injection valve 4 is in a liquid return prevention heart valve form, and can effectively prevent liquid from flowing back.
The utility model discloses during the use, pour into agent 3 through annotating the agent chamber 2 and pouring into the anaerobism type restoration through special notes agent pump. This annotates agent has two aspects effects, can play the liquid spring effect firstly, can adjust the sealing washer thickness according to the seal groove size of difference, makes the sealing washer have sealed elastic sealing's performance. Compared with the common sealing ring, the liquid spring can increase the resistance of sealing plastic deformation and always keep the sealing surface under the action of pressure sealing. On the other hand, the sealed anaerobic repairing injection agent 3 is injected by adopting anaerobic sealing colloid, once leakage occurs under the action of installation or equipment impact, the sealant firstly leaks along a damaged point, the colloid is rapidly solidified after contacting air, the leakage point is blocked, the sealing surface is stroked again, and the autonomous repairing is realized.
