It knits and meets GB/T 9441-2009 evaluation, no slag inclusion, stomata, shrinkage cavity and porosity casting flaw, valve weight 15.3kg.
A kind of multiple flow passages revolving body, it includes above-mentioned casting；Fixation hole is provided on the ears or side handles of a utensil；Four side of pedestal
On be provided with drain tap, drain tap is connected to the runner hole in revolving body casting；It is uniformly distributed and sets on the second-order of described matrix
It is equipped with several annular grooves.
A kind of casting mold being poured above-mentioned revolving body casting, it includes upper die and lower die and sand core, and upper mold and lower die are closed
Mould, forms a type chamber for accommodating revolving body casting, and sand core setting is intracavitary in type；The sand core includes four longitudinal runners, and four
It is connected between longitudinal runner by several chaplets；Longitudinal runner respectively constitutes the runner hole in revolving body casting；The sand
The material of core is by high-intensitive precoated sand and Quench precoated sand；Several cast gates are provided in the upper mold and/or lower die.
Guarantee the size of sand core using stud；Guarantee the intensity of sand core using high-intensitive precoated sand and Quench precoated sand；Benefit
Distributing water inlet is carried out with several cast gates, to reduce iron liquid to the impact force of sand core and stud；Under collective effect, casting is solved
Shrinkage defect guarantees the runner pore size in revolving body casting simultaneously.
The invention has the advantages that design is rationally, structure is simple, while solving Shrinkage Porosity defect, can guarantee to turn round
Runner pore size in body casting.
