End is fixedly connected with support rod, and the second stop sleeve is cased on the support rod, and the support rod and the sliding of the second stop sleeve connect
It connects, primary seal circle is arranged in the outside of the piston, and buffer cover is arranged in the both ends of the piston, and the outer ring of the buffer cover is arranged secondary
Sealing ring, the secondary seal ring are in side of the primary seal circle far from piston.
Preferably, first stop sleeve is fixedly connected by first connecting rod with cylinder body.
Preferably, second stop sleeve is fixedly connected by the second connecting rod with cylinder body.
Preferably, the buffer cover is annular, and buffer cover is fixedly connected with piston by screw, and setting taper is leaked in buffer cover
Hole, the close primary seal circle of the lesser one end in bellmouth aperture.
Preferably, the central axis of the piston, push rod and support rod is on same straight line.
The beneficial effects of the utility model are: support rod is set in this thrust aqueous cylinder pressure, support rod, two stop sleevees
Piston can be supported, piston gravity is overcome, reduces the frictional force of piston underside, enables the primary seal circle on the outside of piston effective
Work；This thrust aqueous cylinder pressure is in meet water side setting secondary seal ring and the cover board of primary seal circle, and buffered water is to primary seal circle
Impact, protect primary seal circle.
This thrust aqueous cylinder pressure is horizontal positioned thrust aqueous cylinder pressure, and stop sleeve can support piston, is reduced under piston
The friction of side enables the primary seal circle on the outside of piston more effectively to work, while protecting primary seal circle.
