Problems solved by technology
[0004] The traditional sealing device can realize the sealing effect in theory, but in the process of machining, the machining accuracy of the upper and lower guard plate arc surfaces is relatively high, and the operating level of the assembly personnel is also very high, and continuous real-time measurement and adjustment are required The gap between the sealing part and the arc surface of the cradle guard plate has high requirements for each link and is inconvenient to disassemble, and the use effect of the active product is not ideal

Abstract
The invention provides an inflatable rubber sealing device. Sealing rubber is embedded into a wedge-shaped groove of a supporting seat, so that the situation that the sealing rubber is rolled out of the supporting seat by the friction force of the pitching action of a gun tube when the sealing rubber is not completely separated from the arc surface of a cradle protection plate, and then a sealingstructure is damaged is avoided. A sealing part is fastened on a protection device through a fastening bolt, so that it is guaranteed that the sealing part has enough rigidity. The section of the sealing rubber is designed to be of an M-shaped structure, protruding lips on the two sides can play a waterproof role under the deflation condition, dust can be effectively prevented, and therefore the effect of protecting rubber in the middle inflation portion is achieved.
Description
technical field [0001] The invention belongs to the technical field of naval guns, and in particular relates to an inflatable rubber sealing device. Background technique [0002] The working environment of naval guns is extremely harsh. The sea surface operating temperature ranges from -40°C to 50°C, and it is always faced with a series of unstable factors such as high concentration of saline and alkali, sunlight aging, oxidative weathering, and corrosion. Therefore, the degree of sealing between the protective device and the arc surface of the cradle guard plate directly affects the service life and operation accuracy of all components in the protective device. [0003] There are many types of rotary seal structures. Traditional seals for naval guns can be divided into: rubber material seals, packing seals, mechanical seals, labyrinth seals, and magnetic fluid seals. [0004] The traditional sealing device can realize the sealing effect in theory, but in the process of mac...
