Description

Technical Field

[0001] The utility model relates to the technical field of gaskets, in particular to an oil drain screw gasket with a coating. Background Art

[0002] Oil drain screw gaskets play a crucial role in numerous applications across the machinery and automotive industries. They are widely used to ensure the integrity of various fluids, such as engine oil and coolant, during storage and transportation, preventing any leakage. These fluids are crucial to the proper functioning of mechanical equipment, so the reliability of these gaskets is directly linked to the performance and safety of the entire system.

[0003] The primary function of an oil drain screw gasket is to form a secure sealing barrier between connected components. This barrier must not only prevent fluid leakage during normal operation but also allow for easy drainage of oil or other media during equipment maintenance, allowing for necessary inspection and replacement. However, existing oil drain screw gaskets are susceptible to prolonged use due to high pressure and media exposure, which can degrade their sealing properties and lead to leakage.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] In response to the problems in the related art, the utility model proposes an oil drain screw gasket with a coating to overcome the above-mentioned technical problems existing in the existing related art.

[0006] To this end, the specific technical solutions adopted in this utility model are as follows:

[0007] A coated oil drain screw gasket includes a gasket body, the surface of which is sprayed with a polytetrafluoroethylene layer, a bottom sealing assembly is provided at the bottom of the gasket body, a groove is provided at the top of the gasket body, a top sealing assembly is provided inside the groove, and the top sealing assembly is connected to the groove by a clamping assembly; wherein the top sealing assembly includes a mounting ring installed inside the groove, and a plurality of arc-shaped sealing rings are provided on the top of the mounting ring in sequence from the inside to the outside.

[0008] Furthermore, to significantly enhance the gasket's sealing capabilities and effectively prevent high-pressure liquid leakage, mounting grooves for two bottom sealing assemblies are provided on the inner and outer sides of the gasket's bottom. The bottom sealing assemblies include an inner sealing ring and an outer sealing ring, which are mounted within the inner and outer mounting grooves, respectively. Both the inner and outer sealing rings have arc-shaped protrusions on their bottoms.

[0009] Furthermore, in order to quickly realize the installation and disassembly of the top sealing assembly and improve maintenance efficiency, the snap-on assembly includes a number of limit blocks installed on the bottom of the mounting ring, and the inner side wall of the groove is provided with a number of limit grooves that cooperate with the limit blocks, and the top of the gasket body is provided with a number of openings that cooperate with the limit blocks and are connected to the limit grooves.

[0010] The beneficial effects of the present invention are as follows: by providing a bottom sealing assembly, a top sealing assembly and a clamping assembly, not only can the sealing ability of the gasket be significantly improved under the action of the bottom sealing assembly and the top sealing assembly, effectively preventing liquid leakage under high pressure, but also the top sealing assembly can be quickly installed and disassembled under the action of the clamping assembly, thereby improving maintenance efficiency. In addition, by spraying a polytetrafluoroethylene layer, the gasket material can be protected from medium erosion and the influence of the external environment, thereby extending the service life of the gasket and reducing the replacement frequency.
