Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing 1-2 and following examples, but do not limit the utility model.
As illustrated in fig. 1 and 2, the water-cooling flange that is applicable to elevated-temperature seal 4 profiles of implementing according to the utility model are a step cutting pattern shape flange arrangement, utilize the first bolt assembly 5 of excircle to be fixed on material flow gate valve housing 6.The second sealing-ring 12 is positioned on the vertical end joined face of water-cooling flange 4 and material flow gate valve housing 6, and the first sealing-ring 2 is positioned on water-cooling flange 4 and end cap 1 junction surface, and two sealing-rings are all in order to prevent the leakage of coal gas.Water-cooling flange 4 has a water-cooling groove 17 near material flow gate valve housing 6 inner chamber places, the lower side of water-cooling groove 17 is along the side that is extended down to sealing member 9, the coal gas of high temperature that enters from material flow gate valve housing 6 inner chambers in order to prevention makes the local temperature of sealing member 9 too high, thereby causes the inefficacy of sealing member 9.Water-cooling groove 17 leaves a circumferential annular opening near material flow gate valve housing 6 inner chamber places, is convenient to the processing and fabricating of water-cooling groove 17.Circular cover 7 is welded in the inboard of water-cooling flange 4, is used for the annular closure of openings on water-cooling groove is got up, and makes the cold water that passes into form the circulation of a sealing.There is a dividing plate 15 at the water-cooling groove middle part, is used for intercepting the water route of the left and right sides.Dividing plate 15 can adopt welding process to be welded in water-cooling flange 4 water-cooling grooves, or directly forms dividing plate 15 with the mode of casting in water-cooling flange 4 water-cooling grooves.Having 16, one, two water holes at the outer downside of water-cooling flange 4 is the prosopyle, and one is posticum, is arranged in the both sides of dividing plate 15, water coolant is flowed through flow out after a circumference in water-cooling groove 17 so that fully cooling, as shown in Figure 1 again.
As shown in Figure 1.Material flow gate valve housing 6 inboards are equipped with thicker heat preserving and insulating material 8, prevent that temperature in material flow gate clack box 6 inner chambers is passed to more heat transfer in the outside of material flow gate clack box 6 up to the temperature of the furnace charge of 800 ℃, cause outside temperature too high, especially affect the Local Property of sealing member 9.
Water-cooling flange 4 links together with material flow gate valve housing 6 by the first bolt assembly 5.Material flow gate valve housing 6 is mainly used to install the variable valve main body that the blanking in blast furnace bucket is regulated, and is the furnace charge of temperature up to 800 ℃ in the clack box inner chamber, and the component that are connected with clack box are had very strong thermal radiation.Sealing member 9 is installed on water-cooling flange 4 near an end of material flow gate valve housing 6 inner chambers.An end by pressure ring 10 is press seal spare 9 closely, makes the trim of sealing 9 can play sealing function, thereby stops the high temperature blast furnace gas in material flow gate valve housing 6 inner chambers.Two bearings 11 are loaded on respectively the two ends, left and right of water-cooling flange 4 inner chambers, separate with distant collar 13 in the middle of two bearings 11, are mainly used to locate the adjacent inboard of two bearings 11.One end of right side bearing 11 is close to the left end of pressure ring 10, makes sealing member 9 reach the sealing matching requirements, and final the location with the step formation of water-cooling flange 4 inner chambers coordinates.End cap 1 links together with water-cooling flange 4 by the second bolt assembly 3.Middle part and the left side bearing 11 of end cap 1 one ends offset, and are used for bearing 11 is positioned.Axle 14 wore end cap 1, left and right bearings at both ends 11, distant collar 13, pressure ring 10, sealing member 9 and water-cooling flange 4 lumen centers holes, formed a complete connected support structure.
During installation, first axle 14 was worn in the corresponding endoporus with one heart of material flow gate valve housing 6.Cover plate 7 is welded in water-cooling flange 4 corresponding side, and carry out seal test, again the first sealing-ring 2 and the second sealing-ring 12 are packed into after determining not leak in corresponding sealing groove, then by the first bolt assembly 5, water-cooling flange 4 and material flow gate valve housing 6 are linked together.Successively more respectively along axle 14 pack into one heart sealing member 9, pressure ring 10, right side bearing 11, distant collar 13, left side bearing 11 and end cap 1.By the second bolt assembly 3, end cap 1 and water-cooling flange 4 are closely connected together again.If when changing sealing member 9, unclamp the second bolt assembly 3, then remove successively end cap 1, left side bearing 11, distant collar 13, right side bearing 11, pressure ring 10, the new sealing member 9 of packing into after then with hook, sealing member 9 hooks being gone out, then repeat aforesaid installation process.
Above embodiment is only for illustration of the utility model; but not to restriction of the present utility model; person skilled in the relevant technique; in the situation that do not break away from spirit and scope of the present utility model; can also make various conversion or modification; therefore all technical schemes that are equal to, all fall into protection domain of the present utility model.
