Fluororubber sealing element

Abstract

The utility model discloses a fluororubber sealing element which comprises a sealing element body of 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 on the upper surface and the lower surface of the sealing element body. And when the bridge part is pressed downwards by external force, the bridge part can be forced to generate a plurality of bent folds, and a sealing effect is formed between the bent folds and an object above, so that the sealing performance is further improved.

Description

Technical Field

[0001] This utility model specifically relates to a fluororubber sealing component. Background Technology

[0002] Fluororubber seals are sealing components made of fluororubber used to prevent leakage of fluids or solid particles from adjacent mating surfaces and to prevent the intrusion of external impurities. Fluororubber is a synthetic rubber with excellent comprehensive properties. Its main components are fluorinated monomers, typically vinylidene fluoride (VDF), tetrafluoroethylene (TFE), and hexafluoropropylene (HFP).

[0003] Fluororubber seals are frequently used in the production of polysilicon in the photovoltaic industry to maintain the seal between the polysilicon reduction furnace and the base. However, in actual use, the sealing effect is not good when using ordinary flat rubber gaskets. Utility Model Content

[0004] The purpose of this invention is to provide a fluororubber seal to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fluororubber seal, comprising a seal body with an annular structure, wherein grooves are provided on both the upper and lower surfaces of the seal body, and bridge portions are integrally formed on both the upper and lower surfaces of the seal body.

[0006] Preferably, the surface of the bridge section has a circular arch bridge structure.

[0007] Preferably, the bridge portion is located vertically above the groove.

[0008] Preferably, the sealing element body has an annular central hole centered on its surface.

[0009] Preferably, the bridge section is provided in two parts, and the two bridge sections are symmetrical.

[0010] The technical effects and advantages of this utility model are as follows: When the bridge part is pressed down by external force, the fluororubber seal can force the bridge part to generate multiple bending folds. The multiple bending folds form a sealing effect with the object above, thereby further improving the sealing performance. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] To facilitate improved sealing, refer to Figure 1 , Figure 2 and Figure 3 As shown, the sealing body 1 has a ring-shaped structure. Grooves 2 are provided on both the upper and lower surfaces of the sealing body 1. Bridges 3 are integrally formed on the upper and lower surfaces of the sealing body 1. When an external force presses down on the bridges 3, the bridges 3 are forced to generate multiple bending folds. The multiple bending folds form a sealing effect with the object above, thereby further improving the sealing performance.

[0018] For ease of use and installation of seal body 1, refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bridge portion 3 has a circular arch structure on its surface. Under pressure, the bridge portion 3 tends to adhere tightly to the groove 2 on the surface of the sealing element body 1. However, the bridge portion 3 does not adhere flatly into the groove 2, but rather forms folds. These folds create a labyrinth seal effect, thereby improving the sealing performance. The bridge portion 3 is located vertically above the groove 2, and the connection points between the two ends of the bridge portion 3 and the sealing element body 1 are a certain distance from the edge of the surface of the sealing element body 1. This allows the bridge portion 3 to better form a complete fold effect after being compressed, further improving the sealing performance. The sealing element body 1 has a centrally located annular hole 4, which facilitates the fitting of the sealing element body onto the surface of the object. There are two bridge portions 3, which are symmetrical. The symmetrical arrangement of the bridge portions 3 allows the operator to place the sealing element body 1 arbitrarily without distinguishing between the front and back, improving practicality. It also enables simultaneous sealing of both sides of the base and the reduction furnace, providing a double sealing effect and effectively improving the sealing performance. When installing it onto the base of the reduction furnace, first place the sealing body 1 on the surface of the reduction furnace base, and then press the reduction furnace onto the sealing body 1. The reduction furnace squeezes the bridge 3, causing the bridge 3 to be forced into the groove 2 and move towards the sealing body 1, so that the bridge 3 forms wrinkles and completes the seal.

[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
