Abstract
The utility model provides a quick-discharging valve which has a good sealing effect. The quick-discharging valve comprises an upper cover, a lower cover and a seal element body which is arranged between the upper cover and the lower cover, wherein a contacting face between the upper cover and the seal element body and a contacting face between the lower cover and the seal element body are respectively provided with an annular seal groove, and the upper contacting face and the lower contacting face of the seal element body are respectively provided with an annular convex rib which is matched with the annular seal groove. According to the quick-discharging valve, the upper cover and the lower cover are respectively provided with the seal groove, and the convex ribs are additionally arranged on corresponding positions on the seal element body, and the seal function is achieved through magnitude of interference between the seal grooves and the convex ribs on the seal element body, so the seal reliability is greatly improved.
Description
Technical field
The utility model relates to a kind of valve body, especially a kind of fast-discharge valve.
Background technique
As shown in Figure 1, the sealing configuration of existing fast-discharge valve mainly relies on the extruding of loam cake 1 and 2 pairs of seal body 3 of lower cover, thereby realizes sealing function, and there is the insecure problem of sealing in this sealing configuration.
The model utility content
The purpose of this utility model provides a kind of fast-discharge valve of good sealing effect.
Realize the fast-discharge valve of the utility model purpose, comprise loam cake, lower cover, seal body between loam cake and lower cover, be respectively equipped with an annular seal groove on the surface of contact of described loam cake and lower cover and seal body, also be respectively equipped with an annular convex rib corresponding with described annular seal groove on the upper and lower surface of contact of described seal body.
The beneficial effect of fast-discharge valve of the present utility model is as follows: fast-discharge valve of the present utility model, in upper and lower cover, opened respectively a seal groove, and also set up a convex tendon in place corresponding to seal body, rely on the magnitude of interference between the convex tendon on seal groove and the seal body to realize sealing function, this structure has improved the reliability of sealing greatly.
Description of drawings
Fig. 1 is existing fast-discharge valve sealed structural representation.
Fig. 2 is the structural representation of fast-discharge valve of the present utility model.
Fig. 3 is the enlarged diagram of Fig. 2 local I.
Embodiment
Embodiment of the present utility model is as follows: shown in Fig. 2,3, fast-discharge valve of the present utility model, comprise loam cake 1, lower cover 2, seal body 3 between loam cake 1 and lower cover 2, be respectively equipped with an annular seal groove 5 on the surface of contact of described loam cake 1 and lower cover 2 and seal body 3, also be respectively equipped with an annular convex rib 4 corresponding with described annular seal groove 5 on the upper and lower surface of contact of described seal body 3.
Fast-discharge valve of the present utility model, in upper and lower cover, opened respectively a seal groove, and also set up a convex tendon in place corresponding to seal body, rely on the magnitude of interference between the convex tendon on seal groove and the seal body to realize sealing function, this structure has improved the reliability of sealing greatly.
Above described embodiment preferred implementation of the present utility model is described; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that those of ordinary skills make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
