To solve the above problems, the utility model adopts the following technical scheme that：
A kind of packing, including body, the body are a ring-type, and the left surface opening position of the body is provided with an annular
Groove, the right flank opening position of the body is provided with the projection for coordinating the groove, more in being internally provided with for the body
Root reinforcement, the reinforcement are solid construction, seal groove are provided with the left surface of the body, the seal groove is coaxially set
Two are equipped with, one of them described seal groove is arranged at the inner ring opening position of the groove, and another described seal groove is arranged at institute
The outer ring opening position of groove is stated, the right flank opening position of the body is provided with the first seal groove for coordinating the seal groove,
The sealing ring of quality of rubber materials is combined between the seal groove and first seal groove, the sealing ring is solid construction.
Preferably, the groove is vee gutter, and the projection is triangular bump, is provided with the inside of the projection in one
Hole, when the projection coordinates with the groove, the projection contacts close to that one end of groove with the bottom of groove, the projection after contact
By the endoporus, crimp occurs, sealing is formed between the projection and the groove, by projection in the direction of the width
Crimp so that projection is expanded in diametric(al) so that projection can form closely sealing between groove and coordinate, and increase is close
Feng Xing, by setting endoporus, the space of projection crimp can be provided.
Preferably, the sealing ring is flexible, and the seal groove forms a full circle after being combined with first seal groove,
The sealing ring agrees with the full circle formed after the seal groove combines with first seal groove, by setting sealing ring
The sealing between two packings being in contact can further be increased, reduce seepage.
Preferably, formed after the steel wire spiral winding that the reinforcement is more than three, by being set in the inside of body
Reinforcement, the tensile strength and compression strength of body can be increased, when installing packing, by being exerted a force in outside so that two
It is in close contact between adjacent packing, packing is deformed in loading process, because reinforcement has diameter, therefore can be avoided
Undue crimp occurs for body.
Preferably, it is 1/5 that the diameter of section of the reinforcement, which is less than the body thickness,.
Preferably, the body is solid construction.
The beneficial effects of the utility model are：The present apparatus can form first layer by the cooperation of groove and projection and seal, and lead to
Can be formed by crossing set sealing ring by two layers and three-layer sealed, effectively ensure the sealing between two combined packings,
Leakage and seepage are avoided, the relatively simple ability of structure of the present apparatus, cost is more cheap, is adapted to promote the use of.
