Description

Fluororubber sealing element Technical Field The utility model relates to a fluororubber sealing element. Background The fluororubber seal is a seal member made of fluororubber for preventing leakage of fluid or solid particles from an adjacent joint surface and invasion of external impurities. Fluororubber is a synthetic rubber having excellent combination of properties, and its main component is a fluoromonomer, usually vinylidene fluoride (VDF), tetrafluoroethylene (TFE), hexafluoropropylene (HFP) and the like. The prior fluororubber sealing piece is often used in the production of polysilicon in the photovoltaic industry, and is used for maintaining the tightness between a polysilicon reduction furnace and a base, but in actual use, a rubber gasket with a common plane structure is directly used, so that the sealing effect is poor. Disclosure of utility model The present utility model is directed to a fluororubber seal to solve the above-mentioned problems of the prior art. In order to achieve the purpose, the fluororubber sealing element comprises a sealing element body with an annular structure, grooves are formed in the upper surface and the lower surface of the sealing element body, and bridge parts are integrally formed in the upper surface and the lower surface of the sealing element body. Preferably, the surface of the bridge part is in a circular arc arch bridge structure. Preferably, the bridge portion is located vertically above the recess. Preferably, the surface of the sealing element body is provided with an annular center hole in the middle. Preferably, the number of the bridge parts is two, and the two bridge parts are symmetrical. The fluororubber sealing piece has the technical effects and advantages that when the bridge part is pressed down by external force, the bridge part can be forced to generate a plurality of bending folds, and the sealing effect is formed between the bending folds and an object above the bending folds, so that the sealing performance is further improved. Drawings FIG. 1 is a schematic view of a first view angle structure of the present utility model; FIG. 2 is a schematic diagram of a second view angle structure of the present utility model; FIG. 3 is a front view of the present utility model; Fig. 4 is a cross-sectional view of the present utility model. In the figure, 1, a sealing element body, 2, a groove, 3, a bridge part and 4, and an annular center hole. Detailed Description The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. In order to be convenient for improve the leakproofness, refer to fig. 1, 2 and 3 and show, including being annular structure's sealing member body 1, recess 2 has all been seted up to sealing member body 1 upper and lower surface, sealing member body 1 upper and lower surface integrated into one piece has bridge portion 3, when external force pushes down bridge portion 3, can make bridge portion 3 forced to produce a plurality of crooked fold, forms sealed effect between a plurality of crooked fold and the object of top to further improvement leakproofness. In order to facilitate the use of the installation seal body 1, referring to fig. 1, 2, 3 and 4, the surface of the bridge portion 3 has a circular arc arch bridge structure. The bridge 3 tends to abut against the groove 2 of the surface of the seal body 1 under pressure, but the bridge 3 does not come into plane abutment into the groove 2 but forms a fold which creates the effect of a labyrinth seal, thereby improving the sealing performance. The bridge 3 is located the vertical top of recess 2, and the both ends of bridge 3 have certain distance with the border position of sealing member body 1 surface apart from sealing member body 1's hookup location to in order to make the bridge 3 receive the extrusion back, the effect of formation complete fold that can be better, further promote sealing performance. The annular center hole 4 is formed in the center of the surface of the sealing element body 1, and the sealing element is more convenient to be sleeved on the surface of an object through the annular center hole 4. The bridge parts 3 are arranged in two, the two bridge parts 3 are symmetrical, the symmetrical bridge parts 3 can be used for the staff to place the sealing element body 1 at will, the front and back of the staff are not needed to be distinguished, the practicability is improved, the sealing of the two sides of the base and the reducing furnace can be realized, and the sealing performance is effectively improved. When the sealing element is installed on a base of a reducing furnace, the sealing element body 1 is firstly placed on the surface of the base of the reducing furnace, then the reducing furnace is pressed on the sealing element body 1, the reducing furnace extrudes the bridge part 3, so that the brid
