Abstract
The invention discloses a water valve block for a composite wear-resisting layer. The wear-resisting layer is connected on the end face/faces of one end or two ends of a substrate, which is/are provided with a water hole or water holes, in a compounding manner. The wear-resisting layer is one out of a ceramic layer, a powder alloy layer and a modified plastic layer. The substrate is made of stainless or modified plastic. The substrate with stronger rigidity and good anti-deformation property is used, and the wear-resisting layer is connected on the end face/faces at one end or two ends of the substrate in a compounding manner. The difficulty that a finished product of the water valve block (the diameter is more than 100 mm) with a large specification has a low machining yield can be overcome. Compared with the prior art, the phenomenon that the end face of the valve block is deformed or broken in a machining process can be obviously reduced; the yield for machining the finished product is improved; and the production cost of enterprises can be effectively reduced.
Description
(1) technical field: the parts that the present invention relates to water treatment apparatus; Be specifically related to a kind of water valve valve block of complex abrasion-proof layer.
(2) background technique: the water valve valve block (diameter dimension is less than 100 millimeters) of state, the medium and small specifications and models of inside and outside existing technology, normally adopt the stronger stupalith manufacturing of wear resistance to constitute.Along with the development of worker, agricultural production and the raising of water treatment demand, to adopt the water valve of big specifications and models during the water treatment enterprise work usually, its valve block diameter dimension is greater than 100 millimeters.If said valve block still adopts the traditional ceramics material manufacture, ceramic valve plate is prone to distortion or cracked because of excessive its end face of diameter dimension very much in course of working, and the up-to-standard rate of finished product processing is extremely low, has increased the cost of production of enterprise significantly.For this reason, present technique field water valve valve block (diameter dimension is greater than the 100 millimeters) difficult problem that the finished product passing rate of processing is low of big specifications and models that needs to be resolved hurrily.
(3) summary of the invention: to the deficiency that above-mentioned existing technology exists, the object of the present invention is to provide a kind of water valve valve block of complex abrasion-proof layer, be intended to improve the finished product passing rate of processing, to reduce the cost of production of enterprise.
Be to realize above-mentioned purpose, technological scheme of the present invention is achieved in that the water valve valve block of this complex abrasion-proof layer, and it is to be provided with the compound wearing layer that is connected with on the end face of one or both ends in water hole at substrate.
When implementing technique scheme, wearing layer of the present invention is the wherein a kind of of ceramic layer, powder alloy-layer and modified plastics layer.
When implementing technique scheme, substrate of the present invention is that stainless steel or modified plastics constitute.
The present invention is through taking said structure; Utilize rigidity stronger; The substrate that anti-deformation is good and at the compound wearing layer that is connected with of the end face of substrate one or both ends has solved water valve valve block (diameter dimension is greater than the 100 millimeters) difficult problem that the finished product passing rate of processing is low of big specifications and models.Compare with existing technology, reduced course of working middle valve plate end face significantly and distortion or cracked phenomenon have occurred, improved the up-to-standard rate of processed finished products, reduced the cost of production of enterprise effectively.

Fig. 6 is the sectional view of the third embodiment's lower valve of the present invention;
Fig. 7 is the plan view of Fig. 6 of the present invention.
(5) embodiment: Fig. 1-shown in Figure 7.The water valve valve block of this complex abrasion-proof layer; According to valve block different working purposes; It is stronger in rigidity; The stainless steel substrate 2 that anti-deformation is good is provided with on the end end face in water hole, constitutes upward valve block (Fig. 1, shown in Figure 2) or lower valve (Fig. 6, shown in Figure 7) through spraying, the sintered combined ceramic wearing coat 1 that is connected with; Can also be provided with on the two ends end face in water hole at said stainless steel substrate 2, constitute middle valve plate (Fig. 3, Fig. 4, shown in Figure 5) through spraying, the sintered combined ceramic wearing coat 1 that is connected with respectively.Wearing layer 1 of the present invention can also be through spraying, the sintered combined powder alloy-layer that is connected with, or through spraying the compound wear-resisting modified plastics layer that is connected with; Described substrate 2 also can adopt rigidity stronger, and the modified plastics that anti-deformation is good constitutes.During work, said valve block can be that upper and lower two valve blocks use (Fig. 1, shown in Figure 6) in pairs; Also can be that (Fig. 1, Fig. 3, shown in Figure 6) used in upper, middle and lower three valve blocks combination.The diameter dimension of valve block is usually at 100 to 260 millimeters; The thickness size of wearing layer 1 is usually at 0.2 to 2 millimeter (Fig. 1-shown in Figure 7).
The above only is a preferred implementation of the present invention.Be noted that for those of ordinary skill in the art under the prerequisite that does not break away from the principle of the invention; Need not other technical characteristics that the process creative work just can be associated; Can also make the modification or the improvement of some kinds of basic identical modes; Realize essentially identical function and produce essentially identical effect, these variations should be regarded as equivalent feature, all belong within the protection domain of patent of the present invention.
