Abstract
Description
Technical Field
[0001] The utility model relates to the field of tire pressure testing devices, in particular to a sealing device for high water pressure bursting test of aviation tires. Background Art
[0002] As we all know, the tire water pressure burst test is an important test item to verify the safety performance of tires. The test principle is to inject water into the tire through a booster pump to increase the water pressure inside the tire until it reaches the specified pressure or damage. In particular, the water pressure burst pressure of aviation tires is required to be greater than 4 times the standard air pressure, up to 6000kPa or more. During the test, ordinary sealing rings are greatly deformed under pressure, joints are easy to break, and high pressure cannot be maintained, causing tire pressure to be deflated, resulting in test failure. Not only does it waste tire test costs, but it is also impossible to obtain the final tire burst pressure result, thereby failing to verify the pressure resistance of the tire, and it also poses a danger to the personal safety of the test operator. Summary of the invention
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a sealing device for a high water pressure bursting test of an aircraft tire, aiming to solve the pressure relief problem during the water pressure bursting process of the aircraft tire.
[0004] The utility model solves the technical problem by adopting the following technical solution: a sealing device for high water pressure burst test of aviation tire, which is provided with an annular wheel rim body, on which a water filling port is installed, and is characterized in that an annular groove is processed on one side of the wheel rim body, two annular sealing grooves are processed in the groove, a sealing ring is embedded in the sealing groove, an annular movable wheel rim is clamped on the groove, a locking ring is embedded between the movable wheel rim and the sealing ring, the locking ring is clamped on the sealing ring, and the sealing ring is composed of two semicircular retaining rings, and the ends of the two semicircular retaining rings are fastened together by bolts.
[0005] The beneficial effects of the utility model are to prevent the pressure release during the water pressure explosion process of the aviation tire, ensure the best sealing effect during the test, ensure the personal safety of the test personnel, normally complete the water pressure performance test, and provide accurate test data for R&D and design personnel. BRIEF DESCRIPTION OF THE DRAWINGS
[0006] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0007] Figure 1 A schematic structural diagram of the utility model.
[0008] In the figure, 1. tire; 2. rim body; 3. water filling port; 4. movable rim; 5. locking ring; 6. sealing ring; 7. groove. DETAILED DESCRIPTION
[0009] In the figure, the utility model is provided with a circular rim body 2, a water filling port is installed on the rim body 2, an annular groove 7 is processed on one side of the rim body 2, two annular sealing grooves are processed in the groove 7, a sealing ring 6 is embedded in the sealing groove, a circular movable rim 4 is clamped on the groove 7, a locking ring 5 is embedded between the movable rim 4 and the sealing ring 6, the locking ring 5 is locked on the sealing ring 6, and the sealing ring 6 is composed of two semicircular retaining rings, and the ends of the two semicircular retaining rings are fastened together by bolts.
[0010] Install the tire 1 into the rim body 2, and fix the movable wheel flange 4 at the tire mouth. After the tire 1 and the rim body 2 are assembled, fill the tire with water from the water filling port 3 of the rim body 2. As the water pressure inside the tire increases, the movable wheel flange 4 squeezes the sealing ring 6 and deforms it. If the size and hardness of the sealing ring 6 do not meet the requirements, water will leak from the movable wheel flange 4, and the tire pressure will be deflated, resulting in test failure. After checking that the tire 1 and the rim body 2 are in place, if there is no leakage, the water pressure bursting test can be started until the tire reaches the specified pressure or bursts.
