Activity compresses contact.
Preferably, the contact plane edge of the automatic-sealed ring is uniformly provided with scalloped recess, and the scalloped recess is to incline
Tiltedly set and inclined upper extreme point is arranged on the ring side of automatic-sealed ring.
Preferably, a trough rim of the scalloped recess be vertical edge, another trough rim be arc-shaped side, and vertical edge with from
The radius of rotary packing ring overlaps.
Preferably, the end face of the manual sealing ring is plane, and the contact plane activity of the automatic-sealed ring is pressed on
On the planar end of manual sealing ring.
Preferably, the automatic-sealed ring is identical with the external diameter of manual sealing ring.
Preferably, the outer ring of the regulation ring is provided with slip-resistant texture.
Compared with prior art, the beneficial effects of the utility model are：The utility model can drive certainly when pump shaft works
Rotary packing ring rotates, and can now have air-flow between automatic-sealed ring and manual sealing ring, and air-flow can flow out of fanning strip,
When the active force of air-flow is more than the pressure of spring, air-flow will make the movement of automatic-sealed ring compression spring so that and manual sealing
Ring is separated, and making it, automatic-sealed ring and manual sealing ring will not produce friction at work, so as to reduce between the two because
Rub and produce heat, to reach the purpose of no water-stop, when pump shaft is stopped, air-flow can gradually decrease, automatic-sealed
Ring resets and compressed with manual sealing ring under the action of the spring to be contacted, and manual sealing ring can adjust left and right by regulation ring and move
Dynamic position, so as to control the pressure between automatic-sealed ring and manual sealing ring to improve the sealing effectiveness of device, tool
Have the advantages that simple in construction, easy to use, using effect is good.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of fan-shaped air force separate type sealing ring,
Automatic-sealed ring 3 and manual sealing ring 6 including valve body 2 and inside the valve body 2, the end of the manual sealing ring 6
