                普通皇冠体育娱乐和高温皇冠app下载的不同

                一、高温钢㊣ 球和常温皇冠app下载的主要区别制造工艺不同,
                二、密封方面区①别:一般常温皇冠app下载是软密封阀座;高温是硬密封(金属或机械碳还有陶瓷等),而且阀内件材质比软密封的要好,
                三、材料处理方面:一般常温球车床加工完以后就可以直接进入装配;高温球还要经过处理(因为不同材质处理的工←艺也不一样,比如渗氮、喷涂等等,这里就不详细说了)
                四、组装:一般常温皇冠app下载拿到零件后可以至接组装;高温皇冠app下载需要研磨球芯和阀座,这道序也很关键,泄漏量的大小就靠研磨了.
