金屬密封球閥具有耐高壓、耐高溫、剪切力強(qiáng)等特點(diǎn)。采用固定球，減少了高壓變形的缺陷。 面醐硬化瞻，并進(jìn)行砌研磨。閥桿物采用石瞄根，奶了阪可能。
Metal-sealed ball valve has characteristics such as high pressure resistance, high temperature resistance, strong shear force, etc. Using fixed ball can reduce the defect of the high pressure deformation. Sphere surface is conducted to harden coating, matching and grinding. The seal of the valve rod uses the prepressing Graphite stuffing to reduce the possibility of leakage.
