a seal assembly for pump body seal comprises a static seal ring, a static ring, a gasket and a pin shaft hole, wherein the static ring which is symmetrical with the static ring in center is arranged at the bottom of the static ring, the static seal ring is sleeved on the outer surface of the static ring, and the gasket is arranged on the contact surface or the lower contact surface of the static seal ring.
As a further improvement, the static seal ring is O-shaped.
As a further improvement, the static seal ring comprises an intermediate butyl rubber layer and a fluororubber layer closely attached to the butyl rubber layer.
As a further improvement, the fluororubber layer and the butyl rubber layer are bonded together with glue.
As a further improvement, the fluororubber layer and the butyl rubber layer are vulcanization molded by a vulcanizing machine.
As a further improvement, the gasket is annular and is provided with a Z-shaped notch with an end face which is horizontally arranged.
As a further improvement, the upper and lower surfaces of the gasket which are intended to be in contact with the notch are provided with a plurality of rough protrusions.
The beneficial effects of the utility model are as follows: according to the utility model, the static seal ring is sleeved on the static ring, and then the static ring is sleeved on the pump body rotating shaft, so that the static seal ring can directly expand when being contacted with the pump body by utilizing the expansion effect carried by the static seal ring, thereby playing a role in sealing, and then the anti-rotation pin shaft is adopted to pass through the pin shaft hole for fixing, so that the static seal ring is prevented from moving outwards due to the pressure difference between the end face of the pump body before and after the operation, and the problem of edge loss of the seal ring caused by the installation of the static seal ring on the pump body rotating shaft is solved.
The gasket can be arranged on the contact surface or the lower contact surface of the static sealing ring to prevent the static sealing ring from being too high in compression rate and incapable of rebounding, so that the service life of the static sealing ring is further prolonged.
According to the utility model, the problem of too high compression rate of the static sealing ring is restrained by layering the butyl rubber layer and the fluororubber layer, so that the service life of the static sealing ring is further prolonged.
