摘要：
A plug assembly for plug valves is made of two distinct metals, one for the plug and another for the stem or trunnion. In a preferred embodiment, the plug is made of ductile iron and the stem or trunnion is made of high grade stainless steel. The two metals are molecularly bonded at their respective surfaces when molten iron is cast into a plug mold containing the steel stem. A mechanical bond is also provided in the form of a iron pin through an aperture in the stainless steel stem.
摘要（中）：
用于旋塞阀的塞子组件由两种不同的金属制成，一个用于塞子，另一个用于杆或耳轴。 在优选实施例中，插头由球墨铸铁制成，并且杆或耳轴由高级不锈钢制成。 当铁水铸入含有钢杆的塞子模具中时，两种金属在其各自的表面分子结合。 机械接合还通过不锈钢阀杆中的孔以铁销的形式提供。
