Abstract
The utility model discloses a valve sealing ring, which comprises a ring body. An annular bulge is arranged at a position at which the inner side of the ring body and a valve clack are in contact in a process of sealing. Because the annular bulge is arranged on the inner side of the ring body of the valve sealing ring disclosed by the utility model, can be in sealed contact, approximate to linear contact, with the valve clack, and has a smaller contact surface with the valve clack, requirements on smoothness when the valve clack is in contact with the ring body are lower, and the sealed contact can be easily kept; therefore, a structure of the valve sealing ring disclosed by the utility model has better sealing effect compared with a traditional structure that the valve clack and the ring body are in contact on large area.
Description
Technical field
The utility model relates to a kind of valve sealing ring.
Background technique
What valve sealing ring in the market generally adopted is that the mode that contacts with valve flap surface is accomplished sealing; And surface of contact is bigger; But this sealing means forms the gap easily, and the easy passage that forms a leakage in these gaps, so sealing effect is relatively poor.
Summary of the invention
The utility model technical problem to be solved provides the better valve sealing ring of a kind of sealing effect.
For this reason, the valve sealing ring that the utility model provides comprises circle body, and position contacting had annular protrusion when the circle body inboard sealed with flap.
Because the circle body inboard of the valve sealing ring that the utility model provides is provided with annular protrusion; Annular protrusion can form the sealing contact that contacts near line with flap; The surface of contact of annular protrusion and flap is less; The circle body of flatness when therefore contacting with to(for) flap requires lower, can more easily keep the sealing contact, so its sealing effect is better than traditional flap and circle body large size contacting structure.
Description of drawings
The structural representation that the valve sealing ring that Fig. 1 provides for the utility model cooperates with flap.
Fig. 2 is the plan view of the flap among Fig. 1.
Embodiment
Like Fig. 1, shown in Figure 2, the valve sealing ring that the utility model provides comprises circle body 1, and position contacting had annular protrusion 3 when circle body 1 inboard sealed with flap 2.In the present embodiment, circle body 1 inboard is provided with twice annular protrusion 3 altogether, keep at a certain distance away between the twice annular protrusion 3, and be that arc shape is protruding at this annular protrusion 3.
Claims (3)
1. a valve sealing ring comprises circle body (1), it is characterized in that: position contacting had annular protrusion (3) when said circle body (1) inboard sealed with flap (2).
2. valve sealing ring according to claim 1 is characterized in that: said circle body (1) inboard is provided with twice annular protrusion (3) altogether, and the twice annular protrusion keeps at a certain distance away between (3).
3. valve sealing ring according to claim 1 and 2 is characterized in that: said annular protrusion (3) is protruding for arc shape.
