Description

Technical Field

[0001] This utility model relates to the technical field of silicone seals, specifically high-temperature resistant silicone seals made of polymer silicone. Background Technology

[0002] Silicone seals possess excellent sealing performance, maintaining good sealing performance even under harsh environments such as high pressure, high temperature, and high humidity. They can be used at extremely low temperatures (below -60℃) and extremely high temperatures (above 200℃) without deformation, aging, or hardening. Silicone seals also exhibit excellent resistance to climate change, being resistant to moisture, corrosion, oxidation, acids, and alkalis. With their superior sealing performance, resistance to high and low temperatures, and resistance to climate change, silicone seals have a wide range of applications.

[0003] However, traditional silicone seals have the following drawbacks:

[0004] Traditional silicone seals have poor aging resistance, and as the usage time increases, they are prone to aging and leakage at the sealing point. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature resistant silicone sealant made of polymer silicone to solve the problem mentioned in the background art of traditional silicone sealants having poor anti-aging coefficients and being prone to aging and leakage at the sealing point as the service time increases.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant polymer silicone sealant, comprising a sealant, the sealant comprising an inner sealing ring and an outer sealing ring, a connecting groove being provided at the bottom of the outer side of the inner sealing ring, the connecting groove being correspondingly provided with the outer sealing ring, a plurality of first grooves being provided on the inner side of the inner sealing ring, a plurality of second grooves being provided on the surface of the inner sealing ring, and a plurality of first protrusions being fixedly installed on the inner wall of the outer sealing ring.

[0007] Preferably, a plurality of second protrusions are fixedly installed on the surface of the sealing outer ring. The installation of the second protrusions improves the unevenness of the sealing outer ring itself, making it easier for the user to handle the sealing component.

[0008] Preferably, a plurality of first anti-slip strips are fixedly installed inside each of the plurality of first grooves. The laying of the first anti-slip strips increases the unevenness of the inner wall of the sealing inner ring, increases the friction coefficient between the sealing inner ring and the sealing point, and increases the stability coefficient of the sealing component.

[0009] Preferably, a plurality of second anti-slip strips located on one side of the first groove are fixedly installed on the sealing inner ring. The laying of the second anti-slip strips increases the unevenness of the inner wall of the sealing inner ring, increases the friction coefficient between the sealing inner ring and the sealing point, and increases the stability coefficient of the sealing component.

[0010] Preferably, a plurality of the second grooves are respectively provided corresponding to a plurality of the first protrusions, and the sealing inner ring and the sealing outer ring are tightly engaged together with the first protrusions through the second grooves.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This seal is made of double-layer silicone material. As the inner sealing ring ages over time, the outer sealing ring continues to seal the sealing area, preventing leakage due to aging and extending the sealing performance of the seal.

[0013] 2. The inner sealing ring of this seal is made of general silicone material, and the outer sealing ring is made of oil-discharging silicone. In order to better fit the two different silicone materials, the second groove and the first protrusion are designed to meet the insertion and extraction force requirements. Multiple adhesion points improve the sealing performance of the seal itself and make it highly practical. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-4This utility model provides a high-temperature resistant silicone seal made of polymer silicone, including a seal 1. The seal 1 includes an inner sealing ring 2 and an outer sealing ring 3. A connecting groove 9 is provided at the bottom of the outer side of the inner sealing ring 2. The connecting groove 9 is correspondingly provided with the outer sealing ring 3. A plurality of first grooves 4 are provided on the inner side of the inner sealing ring 2. A plurality of second grooves 6 are provided on the surface of the inner sealing ring 2. A plurality of first protrusions 7 are fixedly installed on the inner wall of the outer sealing ring 3.

[0021] Several second protrusions 5 are fixedly installed on the surface of the sealing outer ring 3. The installation of the second protrusions 5 improves the unevenness of the sealing outer ring 3 itself, making it easier for the user to pick up the sealing element 1.

[0022] Several first anti-slip strips 8 are fixedly installed inside several first grooves 4. The laying of the first anti-slip strips 8 increases the unevenness of the inner wall of the sealing inner ring 2, increases the friction coefficient between the sealing inner ring 2 and the sealing point, and increases the stability coefficient of the sealing component 1.

[0023] Several second anti-slip strips 10 are fixedly installed on the inner sealing ring 2, located on one side of the first groove 4. The laying of the second anti-slip strips 10 increases the unevenness of the inner wall of the inner sealing ring 2, increases the friction coefficient between the inner sealing ring 2 and the sealing point, and increases the stability coefficient of the seal 1.

[0024] Several second grooves 6 are respectively provided corresponding to several first protrusions 7, and the sealing inner ring 2 and the sealing outer ring 3 are tightly fastened together with the first protrusions 7 through the second grooves 6.

[0025] In this embodiment, the sealing inner ring 2 and the sealing outer ring 3 are tightly fastened together by the second groove 6 and the first protrusion 7. The laying of the first anti-slip strip 8 and the second anti-slip strip 10 increases the unevenness of the inner wall of the sealing inner ring 2, increases the friction coefficient between the sealing inner ring 2 and the sealing point, and increases the sealing stability coefficient of the sealing element 1. The installation of the second protrusion 5 increases the unevenness of the sealing outer ring 3 itself, making it easier for the user to pick up the sealing element 1. The sealing inner ring 2 is made of general silicone material, and the sealing outer ring 3 is made of oil-producing silicone. In order to better fit the two different silicone materials and meet the insertion and extraction force requirements, multiple adhesion points are added to improve the sealing performance of the sealing element 1 itself. Moreover, after the inner ring ages, the outer ring can still seal the sealing point.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
