Abstract
The utility model discloses a vacuum seal ring which is a resilient ring form. An arcuate ring groove is equipped radially on the external surface of the ring form. At least one arcuate scoop channel is equipped on the upper surface and the low surface of the ring form symmetrically. The arcuate ring groove is equipped radially on the inner surface of the ring form. The utility model is used with a connecting clamp at the same time, which can make the airtightness of an abutted flange very good, more particularly when used in vacuum equipment, the utility model can keep favorable evacuation in the vacuum apparatus.
Description
Technical field
The utility model relates to a kind of vaccum seal ring.
Background technique
Seal ring is a kind of conventional machinery element, and it mainly is the sealing problem that solves between the component of machine, as prevent to leak, leakage of oil or gas leakage, its material is selected plastic material mostly for use.The structure of seal ring commonly used has O type circle, V-type circle, sheet type circle or the like.Along with the development of technology, the innovation of mechanical structure, constantly performance and the structure to seal ring proposes new requirement, to adapt to different mechanical structures to the sealing requirement.
Generally between pipeline, housing, mostly adopt the flange plate butt joint, often be connected and fixed with bolt, the seal ring of employing is an O-ring seals, this being tightly connected, prevent dust escape still can, but to prevent gas leakage, effect is not good enough.In order to guarantee good sealing effect, the flange plate of butt joint can adopt clip, and is radially evenly fixing flange plate, and to guarantee good air-tightness, seal ring just must be improved and design again for this reason.
The model utility content
The purpose of this utility model is to improve the shortcoming of prior art, and a kind of vaccum seal ring is provided, and to improve tightness, guarantees the degree of vacuum in the vacuum structure.
For achieving the above object, the utility model is taked following design proposal:
It is the rubber-like annular solid that an outer surface radially is provided with arc-shaped ring groove, the upper surface of described annular solid and lower surface symmetry be provided with at least one arc groove.
The inner surface radial direction of described annular solid is provided with arc-shaped ring groove.
The utility model vaccum seal ring and jointing clip use simultaneously, can make the air-tightness of abutted flange dish good, especially for vaccum-pumping equipment, can keep good degree of vacuum in the equipment.
Description of drawings
Fig. 1 is a sectional view of the present utility model;
Fig. 2 is a user mode schematic representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a rubber-like annular solid 1, its outer surface radially is provided with an arc-shaped ring groove 11, and inner surface radial direction is provided with an arc-shaped ring groove 13, the upper surface of described annular solid 1 and lower surface respectively symmetry be provided with three variform arc grooves 12.
In use, as shown in Figure 2, can put sealed fastening 2 in arc groove 121, described abutted flange dish 3 adopts ring-shaped clip 4 radially evenly fixing flange plate.Form six irregular ladders 14 between described arc groove, described ladder 14 fits tightly with flange plate 3, forms the three seals protection, is equivalent to the sealing effect of three O-ring seals, improves tightness, can better keep the degree of vacuum of device interior.
Claims (2)
1, a kind of vaccum seal ring is characterized in that: it is the rubber-like annular solid that an outer surface radially is provided with arc-shaped ring groove, the upper surface of described annular solid and lower surface symmetry be provided with at least one arc groove.
2, a kind of vaccum seal ring according to claim 1, it is characterized in that: the inner surface radial direction of described annular solid is provided with arc-shaped ring groove.
