Abstract
The utility model relates to an air leakage detection tool of a porous plug of a steel ladle. The tool comprises an upper cover, a lower cover, a connecting rod and a sealing gasket; screw threads are formed at the two ends of the connecting rod; a circular hole is formed in the middle of the upper cover; the sealing gasket is arranged on the lower cover; and the upper cover and the lower cover are connected through the connecting rod and fixed by a nut. The tool has the advantages of simple structure and convenient use, and can accurately detect whether the porous plug leaks air, thereby avoiding heavy accidents such as steel bleed-out.
Description
Technical field
The utility model relates to a kind of testing tool, particularly relates to a kind of ladle porous plug gas leakage testing tool.
Background technology
It is important step during process for making is produced that ladle is reorganized and outfit safety, and kerb weight whether can normally carry out by the qualified STEELMAKING PRODUCTION that not only directly influences, and also is related to problems such as the person, device security.The ladle porous plug directly influences ladle safety in production, changes steel, returns to the molten steel accident if porous plug gas leakage the lighter in handling the molten steel process causes to blow not open, and weight person may cause the great serious accident of bleed-out.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of ladle porous plug simple in structure, easy to use gas leakage testing tool is provided.
In order to address the above problem, the utility model by the following technical solutions:
A kind of ladle porous plug gas leakage testing tool comprises loam cake, lower cover, connecting rod and sealing gasket, and the connecting rod two ends are provided with screw thread, are provided with circular hole in the middle of the loam cake, covers down and being provided with sealing gasket, is connected by connecting rod between loam cake and the lower cover and fixes with nut.
Loam cake is connected with three connecting rods respectively with lower cover, and each connecting rod is symmetrical with respect to the loam cake center.
Compared with prior art, the beneficial effects of the utility model are:
Whether the utility model is simple in structure, and is easy to use, can leak gas by the fast detecting porous plug, prevents security incidents such as molten steel blows not open, bleed-out, guarantees normally carrying out of STEELMAKING PRODUCTION.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
A kind of ladle porous plug gas leakage testing tool, as shown in Figure 1, comprise loam cake 1, lower cover 8, connecting rod 5 and sealing gasket 7, connecting rod 5 two ends are provided with screw thread, be provided with circular hole in the middle of the loam cake 1, lower cover 8 is provided with sealing gasket 7, is connected by three connecting rods 5 between loam cake 1 and the lower cover 8 and fixing with nut 2, and each connecting rod 5 is symmetrical with respect to loam cake 1 center.
Utilize the utility model tool detection porous plug 6 bubble-tight processes to be: porous plug 6 is placed between loam cake 1 and the lower cover 8, porous plug 6 is placed on the sealing gasket 7, with the port sealing of sealing gasket 7 with porous plug 6 tops, then with connecting rod 5 with loam cake 1 with lower cover 8 links together and fixing with nut 2, the breather pipe 3 of porous plug 6 one ends stretches out from the circular hole in the middle of the loam cake 1, and breather pipe 3 afterbodys are connected with flexible pipe 4; Clamping action by loam cake 1 and lower cover 8 is fixedly mounted on porous plug 6 on the utility model instrument.After the installation, the flexible pipe 4 on porous plug 6 tops is connected on the nitrogen trunk line, opens nitrogen valve, feed nitrogen, utilize the Pressure gauge (or nitrogen flow table) on the nitrogen trunk line to detect.If the nitrogen pressure table shows no pressure release or flowmeter and shows the flowing full amount, show that then porous plug 6 is air tight, be certified products; Otherwise, in the testing process,, porous plug 6 gas leakage are described then if Pressure gauge shows pressure release or flowmeter shows that flow is little, be defective work.
