气动固定球阀的特点与优势

<p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">气动固定<strong>球阀</strong>的优势</span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　</span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　<span>1</span><span>、全通径或缩径：可根据需要选用全通径或缩径结构。全通径<strong>阀门</strong>流量孔径与管线内径一致，便于管线清扫。</span></span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　</span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　<span>2</span><span>、阀杆可加长：根据安装或操作的需要，可对阀门阀杆进行加长。加长杆球阀，特别适用于城市煤气等需要埋地铺设管线的场合。加长阀杆尺寸按客户需要确定。</span></span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　</span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　<span>3</span><span>、密封紧急注脂救护：由于介质中的异物或火灾造成阀座密封意外失效，注脂阀提供了与注脂枪的快速连接，方便快捷地将密封脂注入到阀座密封部位，缓解泄漏。</span></span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　</span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　<span>4</span><span>、操作灵活：采用具有小摩擦系数和良好自润滑性的阀座和阀杆轴承，大大地减少了阀门的操作扭矩。因此即使在没有提供密封润滑脂的情形下，也能够长期灵活自如地对阀门进行操作。</span></span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　</span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　<span>5</span><span>、可靠的阀杆密封和低操作力矩：除了设置标准密封套圈外，填料压盖上也设置了</span><span>“O”</span><span>型密封圈，双重密封保证了阀杆密封的可靠性；增设的石墨填料和密封脂注入使火灾后的阀杆泄漏降至*低。阀杆滑动轴承和止推轴承使阀门操作更轻便。</span></span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　</span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　气动固定球阀的特点</span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　</span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　<span>1</span><span>、防火安全结构：阀门都具备防火安全功能，其设计、制造均遵循</span><span>API607</span><span>和</span><span>API6FA</span><span>规范要求。</span></span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　</span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p> <p class="p0"> <span style="font-family:'Times New Roman';font-size:10.5pt;">　　<span>2</span><span>、双阻塞与排放功能：气动固定球阀采用弹簧预紧浮动阀座，无论阀门处于全开或全关状态时，上下游侧的阀座使流体阻断，阀体中腔滞留物通过排放阀排泄。</span></span><span style="font-family:'Times New Roman';font-size:10.5pt;"></span> </p>(完)
