Abstract
The invention provides a novel large length-width ratio hollow-out type fixing guide vane with the simple and reasonable structure, the good rigidity and the high strength. The large length-width ratio hollow-out type fixing guide vane is characterized in that ribbed plates are arranged between an upper vane body and a lower vane body. The ribbed plates are in welded connection with the lower vane body through fillet welds. The ribbed plates are in welded connection with the upper vane body through plug welds. The upper vane body is in welded connection with the lower vane body through groove welds. According to the large length-width ratio hollow-out type fixing guide vane, raw material is greatly saved, the manufacturing cost is lowered, and meanwhile the needed rigidity and strength for fixing the guide vane is guaranteed. After welding, by means of the polishing, a transition fillet is obtained, the manufacturing period is shortened, the manufacturing cost is lowered, the material is saved and the manufacture is simple.
Description
Technical field
The invention belongs to large-scale water turbine and manufacture and design field, particularly relate to a kind of novel seat ring fixed guide vane.
Background technique
Fixed guide vane is the important composition parts of seat ring, also has certain guide functions, therefore need enough Rigidity and strengths while playing important support effect.For large-sized water turbine field ring fixed guide vane, block cast formula fixed guide vane no doubt can ensure enough Rigidity and strengths, but block cast fixed guide vane weight is comparatively large, and cost is higher, process after also needing casting, so just improve manufacture, transport and building site installation cost.
Summary of the invention
The invention provides a kind of simple and reasonable, good rigidity, intensity is high, save material, manufacture easy novel aspect than hollow type fixed guide vane.Technological scheme of the present invention is: a kind of large-scale water turbine aspect is than hollow type fixed guide vane, comprise epivalve body, hypovalve body and some floors, it is characterized in that: between epivalve body and hypovalve body, be provided with floor, floor is connected by fillet weld seam with hypovalve body, floor and epivalve body are welded to connect by plug weld, and epivalve body and hypovalve body are welded to connect by groove weld.
Technique effect:
Fixed guide vane in the present invention is welded structure, relative to the fixed guide vane of cast inblock or forging, greatly reduces the weight of fixed guide vane, reduces the difficulty that seat ring handling and building site are installed, reduces the cost of material of fixed guide vane.
The present invention is simple and reasonable, and the floor between epivalve body and hypovalve body substantially increases the Rigidity and strength of fixed guide vane entirety, ensure that the reliable and not distortion of fixed guide vane intensity in subsequent installation and using process.
Use plug weld to connect between epivalve body and floor in the present invention, manufacturing process is simple, and welding capacity is relatively less, effectively prevents the welding deformation problem caused because thermal weld stress is excessive.
Groove weld is polished into round-corner transition by modes such as relief grindings by the present invention after welding, meets follow-up matching requirements, ensure that the total quality of fixed guide vane and shortens manufacturing schedule, reducing manufacture cost.

Embodiment:
As shown in Figure 1, the invention provides a kind of simple and reasonable, good rigidity, intensity is high, save material, manufacture easy novel aspect than hollow type fixed guide vane, the specific embodiment of the present invention is: a kind of large-scale water turbine aspect is than hollow type fixed guide vane, comprise epivalve body 2, hypovalve body 1 and some floors 3, it is characterized in that: between epivalve body 2 and hypovalve body 1, be provided with floor 3, floor 3 and hypovalve body 1 are welded to connect by fillet weld 5, the leg of fillet weld 5 is not less than 1/3rd of the thinnest mother metal thickness, floor 3 and epivalve body 2 are welded to connect by plug weld 4, the columns of plug weld 4 is identical with the columns of floor 3, often the quantity of row plug weld 4 is not less than 2/meter, epivalve body 2 and hypovalve body 1 are welded to connect by groove weld 6, the degree of depth of groove weld 6 is not less than the thickness of epivalve body 2, epivalve body 2, hypovalve body 1 is arcuate structure and length is consistent, and length is not less than 3000mm, radius is not less than 800mm, thickness is not less than 40mm, epivalve body 2, the material of hypovalve body 1 and floor 3 is the material be equal to Q345 steel mechanical property.
The present invention adopts lobe body welded structure, greatly reduce the weight of fixed guide vane, reduce the difficulty of seat ring handling and building site installation, reduce the cost of material of fixed guide vane, by modes such as relief grindings, groove weld is polished into round-corner transition after welding, meet follow-up matching requirements, ensure that the total quality of fixed guide vane, shorten manufacturing schedule and reduce manufacture cost.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
