Abstract
The utility model relates to the field of mechanical manufacturing, in particular to an anti-scour wear-resisting lining plate which comprises a base plate, a central bulge and a concave cambered surface, wherein the surface of the base plate is a circular plane; the central bulge and the concave cambered surface are located on the surface of the base plate, the central bulge is located in the center of the surface of the base plate, and the concave cambered surface is located around the central bulge. The anti-scour wear-resisting lining plate is applicable to pipelines and equipment for conveying fluids with high solid content and high flow velocity, and is especially applicable to a situation that the flow direction of fluid is perpendicular to the lining plate.
Description
Technical field
The utility model relates to mechanical manufacturing field, particularly a kind of antiscour abrasion-proof backing block.
Background technology
Abrasion-proof backing block is widely used in the lining of industry material transportation magazine, mixing machine, chutes etc. such as mine, harbour, iron and steel, cement, reaches the impact-resistant abrasion-proof effect, and hopper is not damaged; It also is used for industry high solids fluid-transporting tubing and closure plate places such as chemical industry, sewage disposal in addition, plays the impact-resistant abrasion-proof effect equally, prolongs the service life of equipment.
That particularly uses at present relates to closure plate on the vertical plane of action with direction of flow, and from surface structure, its anti-impact brush finish generally is flush type, the antiscour weak effect, and stock utilization is low.
Summary of the invention
At existing not enough, the object of the present invention is to provide a kind of antiscour abrasion-proof backing block that is applicable on the vertical plane of action of direction of flow.
The utility model is achieved through the following technical solutions:
A kind of antiscour abrasion-proof backing block, comprise base plate, central protuberance and spill cambered surface, described backplate surface is a circular flat, described central protuberance and spill cambered surface are positioned at backplate surface, described central protuberance is positioned at described backplate surface center, described spill cambered surface is positioned at around the central protuberance, and described central protuberance is that cone or top are the Rotary-table of sphere.
Beneficial effect of the present invention is:
1, impulsive force has been decomposed at the central protuberance position, and shock point local thickness increases simultaneously, has prolonged service life;
2, the cancave cambered surface around the projection makes direction of flow change gradually, has alleviated fluid washing away internal knuckle walls;
3, stock utilization height;
4, can cast acquisition, make simple.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the concrete application scheme drawing of the utility model in the decompression angle valve.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model comprises central protuberance 1, spill cambered surface 2, base plate 3, described base plate 3 surfaces are circular flat, described central protuberance 1 and spill cambered surface 2 are positioned at base plate 3 surfaces, described central protuberance 1 is positioned at described base plate 3 center of surfaces, and described spill cambered surface 2 is positioned at around the central protuberance 1, and described central protuberance 1 is that the top is the Rotary-table of sphere.
As shown in Figure 2, the utility model be applied to reduce pressure closure plate place, bottom of angle valve, antiscour abrasion-proof backing block 2-1 is installed in tube coupling 2-2 place under the angle valve of decompression angle valve 2-3.
The utility model is by the test on coalification factory Heisui River decompression angle valve, and the result shows that be 6 times with the material liner plate service life.
Described antiscour abrasion-proof backing block if adopt all class wear-resistant materials such as rich chromium cast iron, high manganese steel, can increase the service life.
Claims (2)
