【进口电站止回阀】详细说明:
其遵循的温度、压力等级是*的,在一些管道中存在着某种互换关系。中部采用无阀盖压力自紧式,在高温高压工况下具有良好的密封性能。自密封圈有两种材料:一种是低碳钢,另一种是柔性石墨夹316丝(网)。密封面堆焊钻基硬质合金。其加工后的纯金属层≥3mm,具有耐磨、耐高温、抗腐蚀、抗擦伤、使用寿命长。适用于Class1500~2500Lb、工作温度-29~570℃的石油、化工、火力电站等各种工况的管路上。适用介质为:水、油品、蒸汽等。阀门中腔采用压力自紧式密封结构,内腔压力越高密封性能越好。支管两端为对焊连接,适应不同的接管要求。
It follows the same temperature and pressure levels, and there is some exchange relationship in some pipelines. The middle part adopts pressure self-tightening type without valve cover, which has good sealing performance under high temperature and high pressure. There are two kinds of materials for self-sealing ring: one is low carbon steel, the other is flexible graphite clip 316 wire (mesh). Surfacing of sealing surface with drill-based cemented carbide. The processed pure metal layer (> 3mm) has wear resistance, high temperature resistance, corrosion resistance, abrasion resistance and long service life. It is suitable for pipelines of Class1500-2500Lb and working temperature-29-570 C in petroleum, chemical and thermal power stations. Applicable medium: water, oil, steam, etc. The inner chamber of the valve adopts pressure self-tightening sealing structure, the higher the pressure of the inner chamber, the better the sealing performance. The two ends of branch pipe are butt welded to meet different nozzle requirements.
【进口电站止回阀】特点:
产品设计结构合理,密封可靠,性能优良,造形美观。阀瓣、阀座的密封面采用司太立(stellite)钴基硬质合金堆焊而成,耐磨、耐高温,抗擦伤性能好、使用寿命长。可采用各种配管法兰标准及法兰密封面型式,满足各种工程需要及用户要求。 阀体材料品种齐全,填料、垫片根据实际工况或用户要求合理选配,能适用于各种压力、温度及介质工况。.阀瓣围绕阀座外的销轴旋转,减少关闭时发生猛烈冲击。
销轴与阀瓣连接采用内装式的销轴结构,减小外泄漏点,使用更可靠。
