Metal ball-head is socketed on the outside of cylinder, gland is connected outside metal ball-head, it is close that first is equipped between gland and pen type cylinder
Seal is connected to spacing collar in the upper cover of piston rod of pen type cylinder, and piston rod is mounted on the inner cavity of glass shell, glass shell and gold
The second sealing ring is equipped between category bulb, exterior seal ring, the free end connection strut of piston rod are also socketed on the outside of glass shell
One end, screw rod one end that the other end grafting of strut is moved along strut inner cavity, the other end connection guide rod of screw rod, guide rod
On be also socketed with guide rod trim ring and lower seal, be welded with universal bead on guide rod trim ring, lower seal carries out guide rod trim ring
/V.
In said program, the piston rod of pen type cylinder is connected by hex nut with strut.
In said program, the exterior seal ring is equipped with external screw thread, and gland inner cavity is equipped with internal thread, internal thread and external screw thread
Cooperation makes glass shell be screwed together with gland.
In said program, the gland is aluminium gland.
In said program, the metal ball-head is externally provided with the external screw thread with the screw-internal thread fit of sealing Lv's gland.
The beneficial effects of the utility model are：The lifting stem type reflux ratio distributor, using pneumatic actuation mode, in pen type gas
It is connected with strut, screw rod and guide rod on the piston rod of cylinder in turn, is done in the active force lower band action-oriented bar of written examination cylinder flexible
Movement, the opening and closing under vacuum that entire reflux ratio distributor is enable to smooth out, have the response time it is short, sealing effect
The features such as fruit is good, cracky service life is not long.
