Further, the further outside annular of described main body portion one ora terminalis protrudes out and is formed with a blocked part, described rotating ring has an assembly department, that is round pipe body shape and protrudes out by described assembly department annular end face annular the contact part forming, and described contact part supports on described blocked part.
Further, institute's another ora terminalis of primary seal circle body inwall offers one for installing the quiet lower O-shape ring groove of quiet lower O-shape ring, and described quiet lower O-shape ring is installed in quiet lower O-shape ring groove and described stationary ring encloses in formation holding space.
In sum, a kind of water mechanical sealing device used for pump of the utility model, by the combination of dynamic and static ring, form seal face, the leakage of media fluid be can effectively prevent, in addition, sealing, design requirement easy for installation effectively realized with cooperatively interacting of simple assembly and assembly part, save cost of material, thereby simultaneously on described stationary ring, reached sealing effect better by bolt for described seal ring is fixed effectively.
Brief description of the drawings
Fig. 1 is a cut-away illustration of a kind of water mechanical sealing device used for pump of the utility model.
Embodiment
By describing technology contents of the present utility model, structure characteristics in detail, being reached object and effect, below hereby exemplify embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1, a kind of water mechanical sealing device used for pump 100 of the utility model, sealably ring set is upper at an axle (not indicating in figure), and described water mechanical sealing device used for pump 100 at least comprises a rotating seat 1, a moving lower O-shape ring 2, a moving O pad 3, a moving upper O-shape ring 4, a rotating ring 5, a stationary ring 6, a quiet upper O-shape ring 7, a quiet lower O-shape ring 8, two holding down bolts 9, a spring 10 and a sealing seat 11.
Described rotating seat 1 has roughly main part 110, the rotating ring mounting groove 12 of offering on described main part 110 1 annular end faces 110 of round pipe body shape; on the diapire of described rotating ring mounting groove 12, further offer one for the moving upper O-shape ring groove 13 of moving upper O-shape ring 4 is installed; the inwall medium position of described main part 11 offers the moving lower O-shape ring groove 14 for moving lower O-shape ring 2 and moving O pad 3 are installed; described main part 11 another annular end face annulars protrude out the protection portion 15 that is formed with; in described cut-away illustration, described protection portion 15 is mutually vertical with main part 1.
Described rotating ring 5 has an assembly department 51, that is round pipe body shape and protrudes out by described assembly department 51 annular end face annulars the contact part 52 forming.Described assembly department 51 is installed on rotating ring mounting groove 12; Institute's book contact part 52 supports on described stationary ring 6.Because assembly department 51 can be arranged in mounting groove 12 reposefully, so described at water mechanical sealing device used for pump 100 in when work, can guarantee described rotating ring 5 when work steadily effectively, can not produce swing by a relatively large margin, and then can effectively coordinate with described stationary ring 6, to reach the object of sealing effect preferably.
Described stationary ring 6 has a main body portion 61 that is round pipe body shape, these main body portion 61 1 ora terminalis 1 further outwards annular protrude out and be formed with a blocked part 62, on described main body portion 61, offer two bolts hole (not indicating in figure).Described contact part 51 supports on described blocked part 62.
