Referring to fig. 1 to 3, an embodiment of the present invention provides a multi-lip pan plug seal ring, including: the device comprises a base 1, sealing edges 2 symmetrically arranged at two sides of the base 1 and an elastic piece 5 embedded between the two sealing edges 2; the outer sides of the sealing edges 2 are provided with a plurality of sealing lips 3.

Referring to fig. 1 and 3, a multi-lip pouring plug seal ring according to the present embodiment includes: the device comprises a base 1, sealing edges 2 symmetrically arranged at two sides of the base 1 and an elastic piece 5 embedded between the two sealing edges 2; the outer sides of the sealing edges 2 are provided with a plurality of sealing lips 3. Be equipped with multichannel sealing lip 3 on two sealing edge 2 through general stopper sealing washer respectively, under the effect of embedded elastic component 5 and fluid pressure, make it can play multichannel sealed effect, need not additionally set up the mounting groove moreover, save installation space. The multi-lip flooding plug sealing ring is simple in structure, good in sealing effect and low in cost.

Specifically, the maximum outer diameters of the plurality of sealing lips 3 are the same, that is, the distances from the working surfaces of the sealing lips 3 to the multi-lip flood plug sealing ring are the same, so that each sealing lip 3 can play a sealing role.

More specifically, the section of the sealing lip 3 is serrated, circular arc or a combination of the two, when the section of the sealing lip 3 is in the two shapes, the multi-lip flooding plug sealing ring is in line contact with a part to be sealed during operation, and the function of line sealing is achieved.
