Problems solved by technology
However, it is found in practice that since the screw plug and the radiator header are threaded, the caulking will damage the process of the radiator header itself, and because the plug is very close to the radiator header, the caulking The operation is very inconvenient, so the effect of caulking is often not good, and it is likely that the plug will leak again

Embodiment Construction
[0013] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0014] Such as figure 1 As shown, the present invention provides a plugging device for air cooler plugs, wherein the device includes a sealant injection pipe 3, a support part and a cover 4, and the support part is used to fix the sealant injection pipe 3. The wall of the cover 4 encloses a space 8 with an open end, and one end of the sealant injection pipe 3 communicates with the space 8 and forms a supporting structure with the top of the cover 4 .
[0015] Wherein, the space 8 enclosed by the walls of the cover 4 can accommodate the plug 6 of the air cooler, and, in order to enable the cover 4 to form a closed space around the plug 6, the cover 4 The edges of the opening may be provided with seals, such as gaskets or the like. The cover 4 can cover the leaking plug 6 on the heat radiation pipe header 5 and be pressed on the heat radiation pipe heade...

The invention provides a plugging device for an air cooler plug. The plugging device comprises a sealant injection pipe (3), a supporting part and a cover (4), wherein the supporting part is used for fixing the sealant injection pipe (3); a space (8) of which one end is provided with an opening is encircled by the wall of the cover (4); and one end of the sealant injection pipe (3) is communicated with the space (8) and forms a supporting structure with the top of the cover (4). In the plugging device for the air cooler plug, a sealant is injected into the closed space formed by the cover (4)through the sealant injection pipe (3), so that the balance between inner pressure and outer pressure is realized and the problem that the air cooler plug is leaked is solved; furthermore, the plugging device can securely and reliably plug a leakage part of the air cooler plug under the condition of no production halt, no pressure release and no temperature reduction.
Description
technical field [0001] The invention relates to the field of air coolers, in particular to a plugging device for a plug of an air cooler. Background technique [0002] The air cooler uses ambient air as the cooling medium to cool or condense the high-temperature process fluid in the tube bundle. The air cooler uses an air cooler instead of a water cooler, and the cooling and condensation of the medium can not only save water, but also reduce water pollution. In the cold exchange equipment of refineries and petrochemical plants, air coolers have become an indispensable type of equipment. Its application range includes various working conditions from tower top oil gas condensation to gasoline, diesel, heavy oil and residual oil cooling. In the chemical industry, electric power, metallurgy and other industries, air coolers are also widely used. [0003] Both ends of the tube bundle of the air cooler are connected to the radiator tube header by expansion joints or welding. A ...
