Abstract
The utility model relates to a conical circular seam regulation valve, which includes an inner cone body (1) and an outer cone body (2), wherein a circular seam (4) is equipped between the outer side (1-1) of the inner cone body (1) and the inner side (2-1) of the outer cone body (2), and a wear-resistant material layer (3) is equipped on the inner side (2-1) of the outer cone body (2); the inner cone body (1) is cast steel; the wear-resistant material layer (3) is on the inner side (2-1) of the outer cone body (2) by overlaying welding. The inner and outer cone bodies of the conical circular seam regulation valve respectively use a compound mode of different structure materials, thereby decreasing weight of the outer cone body, reducing manufacture difficulty and saving cost.
Description
Technical field
The utility model relates to a kind of scrubber tower that is used for coal gas dust removal, is specifically related to the taper circumferential weld modulating valve in a kind of scrubber tower.
Background technique
Scrubber tower is the key equipment of wet gas cleaning.Contain a large amount of hard granule dusts in the coal gas that fusion reducing furnace produces in the process of smelting, the effect of taper circumferential weld modulating valve then is this coal gas to be cleaned the back recycle (overbottom pressure can be generated electricity simultaneously) in the scrubber tower.The scrubber tower of present domestic fusion reducing furnace mainly is the scrubber tower that adopts the design of external Austrian steel connection company, the structure of taper circumferential weld modulating valve wherein mainly comprises external cone, internal cones, valve rod and hydraulic pressure installation etc., wherein, external cone is fixed on the tower body of scrubber tower, and internal cones is positioned at external cone and is connected with hydraulic pressure installation by valve rod.
Because the speed of coal gas by internal cones and external cone the time is very fast, for the coal gas that guarantees to have a large amount of hard particles dust can be evenly circumferential weld by inside and outside cone, simultaneously internally, the gauge wear of external cone will be consistent as far as possible, therefore, the manufacturing of the inside and outside cone of present taper circumferential weld modulating valve both domestic and external or the unified mode that adopts spraying wear-resistant materials layer on weldment, or the unified mode that adopts wear resistance castings.If adopt the mode of spraying wear-resistant materials layer, this wearing layer is generally extremely thin, add the spraying became uneven that present domestic manufacture level differs and causes,, then can aggravate concentrated wear and bring the transverse force that acts on inside and outside cone in case thinnest part is worn earlier; If adopt the mode of wear resistance castings, owing to be subjected to the restriction of casting technique, external cone is not subjected to the size of coal gas wearing and tearing part often thicker yet, thereby weight is big, and manufacture cost is also high.
The model utility content
At above-mentioned deficiency, the utility model provides a kind of taper circumferential weld modulating valve, this modulating valve low cost of manufacture, and the weight of external cone is little.
The purpose of this utility model is achieved through the following technical solutions: a kind of taper circumferential weld modulating valve, comprise internal cones and external cone, wherein, be provided with circumferential weld between the outer side surface of described internal cones and the inner side surface of described external cone, the inner side surface of described external cone is provided with wear-resistant material layer; Described internal cones is a Cast Steel.
In order to reduce the weight of described external cone, described wear-resistant material layer is a cobalt-based welding rod layer, the built-up welding of each layer cobalt-based welding rod promptly is subjected to the place of coal gas wearing and tearing on the inner side surface of described external cone, the selection of certain described high-abrasive material layer material and the built-up welding number of plies can be determined according to the technical requirements of reality.
Internal cones of the present utility model and external cone adopt the compound mode of different structure material respectively, be that external cone is only at the local build-up wear-resistant material layer that is subjected to the coal gas wearing and tearing, the thickness of its built-up welding can be determined according to actual needs, very flexible, this structure reduces the external cone weight of taper circumferential weld modulating valve; Internal cones adopts the mode of Cast Steel, is easy to make, thereby has reduced cost of production.This compound mode has overcome the manufacturing or the unified mode that adopts spraying wear-resistant materials layer on weldment of the inside and outside cone of taper circumferential weld modulating valve in the prior art, the unified mode that adopts wear resistance castings, can design inside and outside cone as required respectively, operability is good.
Description of drawings
Fig. 1 is the partial structurtes schematic representation of taper circumferential weld modulating valve among the utility model embodiment 1.
Fig. 2 has the external cone partial structurtes schematic representation of wear-resistant material layer for built-up welding among Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but therefore the utility model is not limited among the following concrete mode.
Embodiment 1: as depicted in figs. 1 and 2, a kind of taper circumferential weld modulating valve comprises internal cones 1 and external cone 2, wherein, be provided with circumferential weld 4 between the outer side surface 1-1 of described internal cones 1 and the inner side surface 2-1 of described external cone 2, the inner side surface 2-1 of described external cone 2 is provided with wear-resistant material layer 3; Described internal cones 1 is a Cast Steel; Described wear-resistant material layer 3 built-up welding are on the inner side surface 2-1 of described external cone 2, the material of described wear-resistant material layer 3 is the build-up wear-resistant material, it is cobalt-based welding rod layer, the built-up welding of each layer cobalt-based welding rod is on the inner side surface 2-1 of described external cone 2, it is built-up welding is subjected to the coal gas wearing and tearing in described external cone 2 place, it is the cobalt-based welding rod of EDCoCr-B-03 or EDCoCr-A-03 that this example is selected model, can certainly adopt other materials as the case may be, the thickness of this wear-resistant material layer 3 also can be determined according to actual needs simultaneously.
Claims (2)
1. taper circumferential weld modulating valve, comprise internal cones (1) and external cone (2), wherein, leave circumferential weld (4) between the outer side surface (1-1) of described internal cones (1) and the inner side surface (2-1) of described external cone (2), it is characterized in that: the inner side surface (2-1) of described external cone (2) is provided with wear-resistant material layer (3); Described internal cones (1) is a Cast Steel.
2. taper circumferential weld modulating valve as claimed in claim 1 is characterized in that: described wear-resistant material layer (3) is a cobalt-based welding rod layer, and the built-up welding of each layer cobalt-based welding rod is on the inner side surface (2-1) of described external cone (2).
