Description
Technical field
The utility model belongs to the valve of high-tension apparatus and high-pressure system, specifically by forging and casting Combined Welding valve that forge piece and cast member combine.
Background technique
Mode for the high pressure valve manufacture of high-tension apparatus or high-pressure system is divided into three kinds: smith forging, casting, the single welding of forging and casting.Three kinds of methods respectively have pluses and minuses: smith forging can crystal grain thinning, material property are played best; Shortcoming only to manufacture simple upright type and tubular element.Simple upright type valve body blank needs to carry out a large amount of cutting, has cut off steel fiber, has reduced forging advantage; Casting is suitable for manufacturing complex-shaped blank, but casting readily occurs pore, defect affect material property such as to be mingled with, reduction casting advantage; The single welding of forging and casting mainly solves the super capacity of equipment problem of object, and valve key component valve body is three-way type or four flow-throughs, and its import, outlet and middle mouth are tubular structure, can forging molding; Remaining part (middle body) is complicated shape, can casting.
Forging and casting Combined Welding method is now adopted to make valve key component valve body, make full use of forging to be easy to make simple upright shape and tubular element, the feature of streamlined Complex Parts is applicable to casting, import, outlet and middle mouth adopt rough forging, the middle body of complicated shape adopts cast blank, adopt suitable welding method and technique to weld each parts, and take necessary quality control method and method, convenient and reliable making valve body blank.
Summary of the invention
The utility model provides a kind of forging and casting Combined Welding valve forge piece and cast member combined, and solves existing smith forging, many deficiencies that casting, valve made by the single welding of forging and casting exist.
The utility model realizes above-mentioned purpose by the following technical solutions:
Forging and casting Combined Welding valve comprises valve body, flap, spool, valve gap, valve rod, valve rod limit plug, pressure strip, pillar, connecting plate, top cover.
Described valve body comprises import body, outlet body, middle mouth body, middle body, and described import body, outlet body, middle mouth body are forge piece, and described middle body is cast member; Described middle mouth body is the structure of threeway, and import body, outlet body, middle body are tubular structure, and described import body and outlet body are welded on middle body both sides, and described middle mouth body is welded on the top of middle body.
The top of described middle body is fixed with valve rod limit plug by valve gap; Described valve rod top is connected with pillar, and post top portion is connected with connecting plate and top cover; Described valve rod is positioned by valve rod limit plug, and the gap filler between valve rod and valve rod limit plug is filled, and described filler is compressed by pressure strip; The top of valve rod is through connecting plate and top cover, and the lower end of valve rod leads to valve inner disease and is connected with flap; Described middle mouth body internal engagement is equipped with the spool of tubular, and described spool and flap cooperatively interact.
The utility model solves forging and the casting characteristic drawback that can not play completely of original scheme, meets maximizations, electric power, petrochemical industry and Coal Chemical Industry system that high parameterization develops be to the requirement of high-temperature high pressure valve performance.This forging and casting Combined Welding valve makes full use of forging, casting, the specific advantage of welding, not only at utmost plays the mechanical property of material, and improves the yield rate of stock utilization and blank, ensure that the performance of High Temperature High Pressure valve body.Therefore, market and the Technique Popularizing prospect of the invention of this model utility are very wide, and its economical, societal benefits are extremely remarkable.
