It touches and forms dynamic sealing face；The outer diameter face of lower connector is connected to sealed body inner diameter seal face, lower connector and central tube, close
The junction for sealing main body is equipped with loading bearing, the two sides of the centrally disposed pipe of loading bearing, and central tube is equipped at dynamic sealing face
Double density sealing groove, double density sealing groove include the v-seal slot of the O shape seal groove and lower section that are disposed over, are provided in O shape seal groove
O-ring seal passes through oil sealing sealing in v-seal slot.
Further technical solution, V-seal slot is interior to be equipped with v-seal part.
Further technical solution, sealed body are equipped with oil filler point, oil filler point be located at loading bearing and alignment bearing it
Between.
The utility model has the beneficial effects that
1, central tube is by being equipped with alignment bearing in upper and lower side two sides in the utility model, by bearing righting, thus
Reduce eccentric wear, sealed body is equipped with oil filler point, and metal (upper is all made of flooding system lubrication, increases wearability, extends the service life.
2, the utility model is by the way that in central tube, by oil sealing sealing, the inner sealing surface formation of seal groove and lower connector turns
Dynamic sealing can automatically adjust compensation since sealing element is v-shaped structure after sealing part abrasion, and sealed pressure is high, uses the longevity
Life length.
3, upper ball cover and main body separate design in the utility model, are easily installed maintenance.
Detailed description of the invention
