高抗硫耐腐蚀的特种球阀
摘要：
本发明涉及阀门技术领域，公开了一种高抗硫耐腐蚀的特种球阀，包括阀球、阀体、位于阀球与阀体间的阀座，阀体上与阀座连接处外侧设置有挡圈，挡圈与阀球外形相适配，挡圈与阀球表面形成一密封副，阀座与阀球间设置有橡胶圈，橡胶圈固定在所述阀座上，橡胶圈与阀球表面形成一密封副，阀球的外表面涂覆有自熔性合金涂层，阀座的材质为耐腐蚀稀土合金钢。采用复合密封结构，保证了球阀的密封性能，同时耐磨性和防腐蚀性好，同时采用了新型的特殊材料和涂层，其耐磨性和抗硫性能大幅度提高，使用寿命长。
摘要（英）：

The invention relates to the technical field of valves, and discloses a high sulfur resistance and corrosion resistance special ball valve. The valve comprises a valve ball, a valve body and a valve base located between the valve ball and the valve body, a check ring is arranged at the outer side of the connecting position of the valve base and the valve body, the check ring is matched with the appearance of the valve ball, a seal pair is formed by the check ring and the surface of the valve ball, a rubber ring is arranged between the valve base and the valve ball, the rubber ring is fixed tothe valve base, a seal pair is formed by the rubber ring and the surface of the valve ball, the outer surface of the valve ball is coated with a self-melting alloy coating, and the valve base is madeof corrosion-resisting rare earth alloy. The composite seal structure is adopted, the seal property of the ball valve is ensured, meanwhile, wear resistance and corrosion resistance are good, meanwhile, a novel special material and a novel coating are adopted, wear resistance and sulfur resistance are greatly improved, and the service life is long.
