[0005] Furthermore, the reinforcing inner ribs are made of silicone rubber.

[0006] Furthermore, the reinforcing inner ribs are evenly distributed along the inner wall of the groove.

[0007] Furthermore, the reinforcing inner rib is in an "H" shape, and two ends of the reinforcing inner rib are respectively connected to the upper top surface and the lower bottom surface of the groove.

[0008] Furthermore, a step is formed at the opening edge of the groove.

[0009] Furthermore, the ring body is made of silicone rubber.

[0010] Through the above technical scheme, compared with the prior art, the utility model has the following beneficial effects: by arranging a number of reinforced internal ribs in the groove of the ring body, the strength of the sealing ring is increased, so that the sealing ring is not easy to deform during use, and the service life is increased, thereby ensuring the sealing effect of the sealing ring; at the same time, the reinforced internal ribs and the ring body are made of silicone rubber, which has the characteristics of high temperature resistance and can be used normally under high temperature conditions of 300 degrees, and the strong aging resistance of silicone rubber can increase the service life of the sealing ring. The above method solves the technical problems of the existing sealing ring that the sealing effect is not easy to ensure and the service life is short under high temperature and high pressure conditions.

[0017] The following will be combined with the attached embodiment of the present utility model Figure 1-2 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0019] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0020] like Figure 1-2As shown: a high temperature resistant and high negative pressure sealing ring, comprising a ring body 1, the ring body 1 is made of silicone rubber, a groove 2 running through the entire inner circumference is provided on the inner ring surface of the ring body 1, a plurality of reinforcing inner ribs 3 are provided in the groove 2, the reinforcing inner ribs 3 are made of silicone rubber, the reinforcing inner ribs 3 and the ring body 1 are integrally formed, and the manner in which the reinforcing inner ribs 3 and the ring body 1 are integrally formed makes the two form a whole, which can further increase the strength of the sealing ring and thus increase the service life of the sealing ring.

[0021] The ring body 1 is an annular ring body. A plurality of reinforcing inner ribs 3 are arranged in the groove 2 of the ring body 1 to increase the strength of the sealing ring, so that the sealing ring is not easily deformed during use, and the service life is increased, thereby ensuring the sealing effect of the sealing ring. At the same time, the reinforcing inner ribs 3 and the ring body 1 are made of silicone rubber. Silicone rubber has the characteristics of high temperature resistance and can be used normally under high temperature conditions of 300 degrees. The strong aging resistance of silicone rubber can increase the service life of the sealing ring. The above method solves the technical problems of the existing sealing ring that the sealing effect is not easy to ensure and the service life is short under high temperature and high pressure conditions.

[0022] like Figure 1-2 As shown: the reinforcing inner ribs 3 are evenly distributed along the inner wall of the groove 2. By arranging the reinforcing inner ribs 3 in the groove 2 in a uniform and separate manner, the reinforcing inner ribs 3 can cover the entire groove 2. This embodiment uses 6 groups of reinforcing inner ribs 3 according to the overall size of the sealing ring, so that each contact surface in the sealing ring can be affected by the reinforcing inner ribs 3.

[0023] like Figure 1-2 As shown in FIG. 1 , the reinforcing rib 3 is in an “H” shape, and the two ends of the reinforcing rib 3 are respectively connected to the upper top surface and the lower bottom surface of the groove 2. Figure 2 As shown: a step 4 is formed at the opening edge of the groove 2. The reinforcing inner ribs 3 extend to the step 4 on both sides and are integrally connected to the step 4 to increase the strength of the sealing ring. Specifically, 6, 8, 10, and 12 equal transverse ribs are arranged at both ends of the reinforcing inner ribs 3 along the circumferential direction of the groove, and these equal transverse ribs extend to the step 4, i.e., the sealing lip and tongue, so that the two are integrally connected. In this way, the compression rate and resilience of the sealing lip and tongue under high temperature and high negative pressure are enhanced.

[0024] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
