Summary of the invention
Technical problem to be solved in the utility model provides a kind of steel plant continuous casting two metamerism roller water test units, utilize this test unit that two metamerism rollers are done the hydraulic testing, leak when avoiding the work of two metamerism rollers, guarantee the cooling effect of equipment, improve the product quality of continuous casting billet, reduced the overhaul of the equipments cost.
For solving the problems of the technologies described above, the utility model steel plant continuous casting two metamerism roller water test units comprise water tank, three valve plates, three block pressur plates, six roots of sensation stay-bolt and hydraulic power unit, described three valve plates are respectively equipped with the Inlet and outlet water passage and are located at described water tank end face at interval, described six roots of sensation stay-bolt one end activity respectively is located at described water tank end face both sides and is positioned at described three valve plate positions, described three block pressur plate two ends have through hole and are inserted in two stay-bolts of described three valve plate both sides respectively, the described six roots of sensation stay-bolt other end is screwed with nut respectively, and the inlet channel of described hydraulic power unit connects described water tank bottom, outlet conduit connects the intake tunnel of described three valve plates respectively.
Further, this test unit also comprises three rubber gaskets, and described three rubber gaskets are interval with two through holes respectively and are located at described three valve plate end faces, and two through holes of described rubber gasket are communicated with the Inlet and outlet water passage of described valve plate respectively.
Because the utility model steel plant continuous casting two metamerism roller water test units have adopted technique scheme, be that this device comprises water tank, three valve plates, three block pressur plates, six roots of sensation stay-bolt and hydraulic power unit, three valve plates are respectively equipped with the Inlet and outlet water passage and are located at the water tank end face at interval, six roots of sensation stay-bolt one end activity respectively is located at water tank end face both sides and is positioned at three valve plate positions, three block pressur plate two ends have through hole and are inserted in two stay-bolts of three valve plate both sides respectively, the six roots of sensation stay-bolt other end is screwed with nut respectively, and the inlet channel of hydraulic power unit connects the water tank bottom, outlet conduit connects the intake tunnel of three valve plates respectively.This test unit is done the hydraulic testing to two metamerism rollers, leaks when avoiding the work of two metamerism rollers, guarantees the cooling effect of equipment, has improved the product quality of continuous casting billet, reduces the overhaul of the equipments cost.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the utility model steel plant continuous casting two metamerism roller water test units;
Fig. 2 is the side view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, the utility model steel plant continuous casting two metamerism roller water test units comprise water tank 1, three valve plates 2, three block pressur plates 4, six roots of sensation stay-bolt 3 and hydraulic power unit 6, described three valve plates 2 are respectively equipped with the Inlet and outlet water passage and are located at described water tank 1 end face at interval, described six roots of sensation stay-bolt 3 one ends activity respectively are located at described water tank 1 end face both sides and are positioned at described three valve plate 2 positions, described three block pressur plates 4 two ends have through hole and are inserted in two stay-bolts 3 of described three valve plate 2 both sides respectively, described six roots of sensation stay-bolt 3 other ends are screwed with nut 5 respectively, and the inlet channel of described hydraulic power unit 6 connects described water tank 1 bottom, outlet conduit connects the intake tunnel of described three valve plates 2 respectively.
Further, this test unit also comprises three rubber gaskets 7, and described three rubber gaskets 7 are interval with two through holes respectively and are located at described three valve plate 2 end faces, and two through holes of described rubber gasket 7 are communicated with the Inlet and outlet water passage of described valve plate 2 respectively.Arrange when 7 pairs of continuous castings of rubber gasket, two metamerism rollers 9 are seated three valve plates 2 effective protection is provided, avoid the damage of three bearing seats 8 of continuous casting two metamerism rollers 9.
