Having the first through hole of the first internal diameter, described second main part is axially formed has the second of the second internal diameter
Through hole, described first through hole and the second through hole be connected, and described first internal diameter is less than described second internal diameter,
The end inward flange of described first main part is formed with peace in the first step portion of annular, described second through hole
Sealing ring equipped with annular.
Preferably, in the above-mentioned stationary ring for mechanical seal, described sealing ring convexedly stretches in described
The end of two main parts.
Preferably, in the above-mentioned stationary ring for mechanical seal, the end of described stationary ring is formed
The second step portion communicated with described second through hole.
Preferably, in the above-mentioned stationary ring for mechanical seal, described second step portion has arc
Base angle.
Preferably, in the above-mentioned stationary ring for mechanical seal, described 3rd main part with axially in
45 ° of angles.
Preferably, in the above-mentioned stationary ring for mechanical seal, described second main part and described the
The seal groove of the annular recessed along vertical axial direction it is formed with between three main parts.
Preferably, in the above-mentioned stationary ring for mechanical seal, on the sidewall in described first step portion
Offering the breach of cross section semicircular in shape, this breach is communicated in described first through hole.
Compared with prior art, it is an advantage of the current invention that: the stationary ring simple in construction of the present invention, seal
Effective.
