Description

Technical Field

[0001] The utility model relates to the technical field of air-temperature type vaporizers, in particular to an air-temperature type vaporizer leakage prevention device. Background Art

[0002] At present, there are several types of vaporizers used in China, including electric heating, electric water bath, hot water circulation, and air temperature. Judging from the current domestic applications, air temperature vaporizers are still "new things" for many users. In addition, their use is indeed greatly affected by the temperature. The core part of the air temperature vaporizer is the heat exchange device, which obtains more powerful heat energy from the atmosphere in the smallest possible space.

[0003] Most of the internal parts of the gasifier are gasification pipes, and the gasification pipes need to be connected. The current existing connection method is basically to connect the gasification pipes through connecting flanges. However, since the gasification pipes generally contain high-temperature and high-pressure gases, leakage may occur at the gasification pipe connections during long-term use. Therefore, the existing solution is usually to add a leak-proof device at the gasification pipe connection. The current leak-proof device usually uses two sets of symmetrical protective covers to cover the pipe flange connections, and then seals the protective covers. This leak-proof sealing performance is relatively simple, and the gap at the flange connection cannot be sealed, resulting in poor sealing performance of the leak-proof device, and it is inconvenient for staff to detect gasifier leakage during use.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0022] As a technical optimization scheme of the utility model, the adjusting mechanism includes a rotary sealing seat 2, and the rotary sealing seat 2 is fixedly installed inside the protective body 1, the internal sealing rotation connection of the rotary sealing seat 2 is provided with a sealing shaft 12, and the upper end of the sealing shaft 12 is fixedly connected with a knob 3, the lower end of the sealing shaft 12 is fixedly connected with a screw 13, and the lower end of the screw 13 is threadedly connected with a screw sleeve 11, the lower end of the screw sleeve 11 is fixedly connected to the outer surface of the semicircular pressure plate 10, through the knob 3, the sealing shaft 12, the screw 13 and the screw sleeve 11 in the adjusting mechanism, the semicircular pressure plate 10 can be pushed toward the flange connector 6 after the protective body 1 is installed, so that the semicircular sealing strip 9 on the inner side of the semicircular pressure plate 10 is tightly squeezed to the inner side of the flange connector 6, and the sealing performance of the gasifier pipeline connection is further increased.

[0023] As a technical optimization solution of the utility model, the outer surface of the protective body 1 is fixedly connected with a mounting plate 5, and arc-shaped grooves 14 are provided on both side surfaces of the protective body 1, and the inner surfaces of the mounting plate 5 and the arc-shaped grooves 14 are fixedly connected with sealing strips 8, which can preliminarily seal the pipeline of the gasifier when installing the anti-leakage device.

[0024] As a technical optimization scheme of the utility model, the driving assembly includes a sealing plate 404, and one side surface of the sealing plate 404 is fixedly connected to one end of the inspection protrusion 402, the other end of the sealing plate 404 is fixedly connected to a support rod 405, and one end of the support rod 405 is fixedly connected to a push plate 406, and the push plate 406 and the sealing plate 404 are both slidably connected to the inner wall of the inspection tube 4. When a leak occurs in the gasifier, the push plate 406 inside the inspection tube 4 will be pushed to move outward. At this time, the push plate 406 will push the inspection protrusion 402 to move out of the inner side of the limit ring 401, thereby facilitating the staff to quickly discover the leakage of the gasifier.

[0025] As a technical optimization solution of the utility model, a sealing gasket 403 is provided on the outer side of the inspection protrusion 402, and the sealing gasket 403 is fixedly connected to the side surface of the sealing plate 404. After the gas leaked from the gasifier pushes the push plate 406 to move outward for a certain distance, the sealing gasket 403 will press against the inner surface of the limiting ring 401, thereby sealing the inside of the inspection tube 4. The more gas leaks, the tighter the sealing gasket 403 will seal, further preventing gas leakage. The outer diameter of the limiting ring 401 is the same as the outer diameter of the inspection tube 4, and the inner diameter of the limiting ring 401 is smaller than the outer diameter of the sealing plate 404 but larger than the outer diameter of the inspection protrusion 402, so as to prevent the sealing plate 404 from being pushed out of the inspection tube 4 when the leaking gas pushes the push plate 406 to move outward, thereby failing to seal the inspection tube 4.

[0026] When the utility model is in use, the symmetrical protective bodies 1 are aligned with each other, and the semicircular sealing strip 9 on the inner surface of the semicircular pressure plate 10 inside the protective body 1 is aligned with the gap in the middle of the flange connector 6, and then the protective body 1 is snapped onto the side surfaces of the flange connector 6 and the air duct 7, and the protective body 1 is installed together through the mounting plate 5 and bolts on the side surface of the protective body 1. After installation, the staff can rotate the screw 13 through the knob 3, so that the screw 13 pushes the semicircular pressure plate 10 close to the flange connector 6 through the threaded sleeve 11, and then the semicircular sealing strip 9 on the inner surface of the semicircular pressure plate 10 will gradually extend into the gap of the flange connector 6, thereby re-sealing the gasifier pipeline connection, thereby reducing the leakage of the gasifier pipeline.
