Description

Technical Field

[0001] The utility model relates to the technical field of sealing components, in particular to a high temperature resistant mechanical sealing component. Background Art

[0002] A mechanical seal is a device that prevents fluid leakage by at least one pair of end faces perpendicular to the axis of rotation, which remain in contact and slide relative to each other under the action of fluid pressure and the elastic force (or magnetic force) of a compensation mechanism and the cooperation of an auxiliary seal. Mechanical seals are mainly composed of four types of components: main seals, auxiliary seals, clamping parts and transmission parts.

[0003] Although the mechanical seals in the prior art have the characteristics of high temperature resistance, the compactness and stability of the sealing part connection of the mechanical seal are poor, thereby reducing the sealing effect and stability of the overall mechanical seal device. Therefore, it is urgent to design a high temperature resistant mechanical seal to solve the above problems;

[0004] According to the existing patent (Announcement No.: CN217356000U), a high temperature resistant mechanical seal comprises a first pipe fitting and a second pipe fitting, an outer thread groove is provided at the bottom of the outer wall of the first pipe fitting, and an inner thread groove is provided on the top outer wall of the second pipe fitting, the first pipe fitting and the second pipe fitting are threadedly connected under the action of the outer thread groove and the inner thread groove, and an annular groove is provided at the center of the inner wall at the bottom of the inner thread groove. After the first pipe fitting and the second pipe fitting of the utility model are threadedly connected under the action of the outer thread groove and the inner thread groove, the ring block pushes the top ring to fit with the bottom outer wall of the outer thread groove under the action of the ring plate and the spring, and the sealing gasket improves the sealing and stability of the first pipe fitting and the second pipe fitting after the connection under the action of the top ring, and the nut is threadedly connected to the bottom of the outer wall of the bolt, so that the bolt can tighten the lug plate under the action of the nut, which greatly improves the stability of the first pipe fitting and the second pipe fitting after the connection.

[0005] However, the above technical solution still has certain shortcomings. First, the device uses an anti-corrosion layer on the outside of the first pipe to prevent rust on the device, and a ceramic layer and a high-temperature resistant layer are arranged inside to improve the heat resistance of the device. However, the device can only isolate high temperatures. However, if the material is transmitted under high temperatures, the thermal expansion and contraction of the pipeline may cause the strength of the pipeline to weaken, and the airtightness is greatly reduced, which ultimately affects production safety. For this reason, a high-temperature resistant mechanical seal is proposed. Utility Model Content
