Definitions
- the invention relates to a water-cooled housing for hot wind valves according to the preamble of claim 1, as used, for example, in hot-water systems, blast furnaces or high-temperature test benches in test facilities.
- German patent specification 23 64 915 describes a water-cooled housing for hot wind valves with the features of claim 1, one cooling water ring channel in the same cooling water circuit in the flow direction of the hot wind in front of the guide space and one cooling water channel in the flow direction of the hot wind behind the guide space ⁇ run are directly connected in series.
- Such a housing has proven itself in practical operation, but it is seen as a disadvantage that the production of the housing, which is usually designed as a welded construction, is relatively complex, since a relatively large number of components have to be produced to form the cooling water ring channels, which then have to be connected with a corresponding number of welds.
- a water-cooled housing for hot-wind valves is also known according to German specification 23 28 085.
- This is a water-cooled high-temperature slide, in particular a hot-wind slide, in which ring channels for the coolant (water) are provided in the housing, which are from the upper part of the slide valve. Also run along the sealing strips on both circumferential sides to the lower region of the housing and open into at least one cooling channel via transition openings provided at this point, which extends around the region of the housing arranged around the slide plate to the housing upper part, in which the Coolant outlet is located, runs back, the flow cross section of the cooling channel, in which the coolant is returned, at least in its lower, 180 ° area, being smaller, but at most the same size as the total flow cross section of the ring channels.
- the inventor set himself the task of increasing the reliability and effectiveness of the cooling in the case of high-temperature slides, in particular hot-wind slides, while at the same time simplifying and reducing costs and reducing the space requirement of the housing construction.
- This housing is also designed as a welded construction and has a very complicated structure, since special baffles are provided in the cooling water chamber in order to maintain a cooling water speed which is sufficient to entrain solids in the cooling water, which means that Manufacturing effort is increased and is considered a disadvantage.
- a hot wind valve according to EP 0 171 754 AI is known.
- This is a hot-wind valve, in particular for blast furnace hot-wind systems, consisting of a valve housing formed from sheet metal, a valve plate, a valve cover attached to the valve housing, which serves to receive the valve plate when the valve is open, seats, two between which the slide plate is in the closed state, cooling ducts and refractory protective linings towards the hot wind side, the seat against which the slide plate is supported in the closed state being made of metal which is in thermal contact with a coolant, and the named The opposite side of the seat consists only of refractory material.
- the hot wind valve claimed here therefore has cooling channels only towards the hot wind side, which is considered to be disadvantageous in relation to the cooling effect under high stress.
- the structure on the hot wind inlet side is just as complicated and complex to manufacture as in the housings described above.
- DE-OS 25 38 357 discloses a high-temperature slide valve, in particular a hot-wind slide valve, with a water-cooled slide valve housing provided with two end flanges, which has coolant channels and, in particular, water-cooled sealing strips and a chamber arranged transversely to the longitudinal axis of the flow cross section of the gas feedthrough in which a slide plate for closing and opening this flow cross-section is guided, an actuating device being detachably attached to the housing at one end of this chamber, the entire central part of the slide housing enclosing the chamber for the slide valve plate in all Sides are rectangular in shape and on the front side opposite the installation side for the actuating device is provided with an end wall.
- coolant channels are provided within the sealing strips, which connect outside of the central part and all around the tubular extension pieces of the slide valve housing, the cooling water initially flowing through the sealing strips being connected to the cooling water outlet.
- the present invention is based on the object of further developing a generic housing for hot wind valves while maintaining the stability and cooling effect in such a way that manufacture becomes simpler and the welding work involved is reduced.
- the production is greatly simplified by the use of a housing component each having annular recesses on each outer side facing the piping.
- the ring channels are partly integrated into these components and partly formed from ring-shaped components which close the recesses.
- only three components are required on each of the two outer sides in order to form two concentrically nested ring channels.
- the recesses for the outer ring channels of the ring channels which are arranged concentrically one inside the other, are open towards the flanges and that the recesses for the inner ring channels of the pair of ring channels, which are inside one another, are open towards the slide plate, each of the one-piece housing components, each with two annular recesses, essentially rotationally symmetrical to one parallel to the flow.
- the housing components can be produced simply and economically by turning.
- the legs of the U-shaped area lying towards the axis are shorter than the respectively opposite legs, the second ring-shaped component expediently having a U-shaped cross section with legs of different lengths, which has the U-shaped area of the housing component to form the inner annular channel.
- the first ring-shaped component expediently has the form of an essentially flat ring-shaped steel plate for forming the outer ring channel. This is this component can be produced particularly easily from a plate, for example by means of a cutting line or burning process.
- first annular components can be connected to the housing components by means of a weld seam running on their inner and outer diameters.
- welding in is easily carried out by means of two round seams in easily accessible places.
- the second annular components can be connected to the housing components by means of a weld seam running at the free ends of the legs. As a result, this welding process can also be carried out economically without difficulty.
- the lugs according to the invention which are in contact with the slide, can be replaced particularly inexpensively. Furthermore, the symmetry ensures that no excessive struts or the like are necessary, as is the case with the asymmetrical design, which inevitably has unequal force distributions. The construction is therefore advantageously less expensive and the construction is lighter and simpler.
- connection of the cooling water supply and discharge corresponds to the state of the art e.g. according to the specification 23 64 915 and is not explained in more detail here.
- FIG. 1 shows a cross section of a section of a housing according to the invention and in Figure 2 shows a cross section of a housing according to the prior art.
- a housing 20 shown as a detail in the lower region, which is blown by the hot wind in the direction of arrow A, has a typically water-cooled slide plate 21, which is shown in the closed state and in the direction of arrow B by known, for example electric or hydraulic drive (not shown), can be opened.
- the housing 20 has, on the side opposite the inflow side, an essentially rotationally symmetrical housing component 22 formed around a central axis M running parallel to the direction of flow A, the ring-shaped region 23 beginning at the largest diameter D and running towards the central axis M having a flange for connection forms on a pipe, not shown. In the flange there are bores for manufacturing e.g. a screw connection with the pipeline.
- the cross section of the housing component 22 is developed in connection with the annular region 23 in the form of an axial region 24, the portion of which directed towards the slide plate 21 forms a first part 25 of the wall of an outer annular channel 26.
- the section 25 merges into a second section 27, which extends radially to the central axis M and forms a second part of the wall of the outer annular channel 26.
- the section 27 abuts at right angles with rounded corners on a section 28 which is in the form of a lying U which is open towards the slide plate 21 and whose leg located towards the central axis M is shorter than the other, the U-shaped cross section being a part of the section Wan- d ng of an inner ring channel 29 forms.
- a housing component 22 ' Arranged on the inflow side of the housing is a housing component 22 'which is mirror-symmetrical to the housing component 22 and has the corresponding features, for which reason a detailed description is dispensed with.
- annular depression formed by the sections 25, 27 and the part of the U-shaped cross section 28 directed towards the flange is closed with a first annular component 30 to form the outer annular channel 26, for which purpose annular weld seams are drawn at C and E.
- the inflow and outflow for the coolant, usually water, flowing in the annular channels 26, 29 are conventional and not shown.
- a second ring-shaped component 31 is placed on the free ends of the legs of the U-shaped cross section 28 to form the inner ring channel 29, the component 31 having a U-shaped cross section with legs of unequal length, the axis M read leg is longer than the other, so that the inner annular channel 29 has a cross section approximately in the form of a rectangle elongated parallel to the direction of flow A longitudinally.
- the two ends of the legs of the two U-shaped parts are connected by two ring-shaped weld seams at F and G.
- the housing has, on the side opposite the inflow side, a refractory lining 40 made of ceramic material, which is arranged between the housing component 22, the first and second annular components 30, 31 on the one hand and the interior space acted upon by the hot wind is.
- a refractory lining 41 is arranged on the inflow side, the inner diameter D 'of which decreases continuously towards the slide plate 21, while the inner diameter d of the refractory lining 40 is constant.
- a cross-sectional dar ⁇ posed hot blast valve housing 1 according to the prior art, two flanges 2 ⁇ 2 Z for connection with non-ge showed pipelines, a guide space 3 for a slide plate 4 and concentrically one inside seated cooling water annular channels 5, 6 and 7, 8 on. Fireproof linings 9, 10 are provided toward the hot wind, which flows in in the direction 11.
- the inner ring channels 5, 6 each have two components which are each connected by two ring-shaped weld seams, and that the outer ring channels 7, 8 each have three further components which each have four further ring-shaped weld seams are connected.
- a flange part with a further weld seam is provided in each case.
- the housing according to the invention for hot-wind valves requires three components and four weld seams on each side and represents a significant simplification in terms of construction and manufacture.
