性能特点
1、体、支架均锻造后固融处理,结构紧密无裂痕,耐高温高压效果优越
2、阀座堆焊硬质合金司太立6号,高温硬度达50HRC以上
3、杆锻造后取得了良好的抗拉强度和屈服强度,承受高温高压性能优越
4、为司太立8号整体锻制而成,高温硬度达HRG58以上,与阀座形成了合适的硬度差,互相配合后具有良好的抗冲
刷、抗气蚀性能。
5、阅体内置阀杆导向座,阀门长期反复开关时,阀瓣回座率达100,保持了良好的密封性能
6变架上端置阀杆直升降装置,阀门开闭时,阀杆的无旋转直升降运动不仅减少了对填料的磨损,而且启闭力小,手
松
7、致密和回弹性优良的柔性石墨填料,确保阀门不外漏
Performance characteristics
1. The body and supporting are all solid melting treated after forged. The structure is compact without any crack. High temperature
d high pressure resistant performance is excellent
The seat is buill-welded with hard alloy steel STL 6, the hardness is more than 50HRC
3. The stem has good tensile strength and yield strength after forged, High temperature and high pressure resistant performance is
excellent
4. The petal is integrally forged by STL 8, the hardness is more than 58HRC, it has suitable hardness difference with the seat
5. There is valve stem guide seat in the body, after the valve is opened and closed repeatedly for a long time, the retum rate of the
petal is 99%. The sealing performance is good.
6. Stem straight lifting device is on the top of the supporting. when the valve is opened and closed, non rotating lifting movement of
the stem can reduce the wear of the filler. The opening and closing force of the valve is small
7. Flexible graphite filler is compact and its elastic resilience is excellent, this can guarantee the vale has no extemal leakage

安装维护说明
1、产品出厂时已经严格检验,请勿解体,可打光谱,可试压
2、阀门尽可能按阀杆垂直水平面安装,如需其他方法安装,请说明
3、安装时应使介质流向与阀体所示箭头方向一致,切勿装反
4、次使用时,须全开阀门,对阀门及管道进行清洗。调整压板螺母,确保填料处于良好密封状态
5、运行中,当工況温度变化较大(如停机维修)时,裣查并旋紧压板螺母,压紧填料。以防阀杆处外温
Installment and maintenance instructi
1. Our valves have been examined strictly when leave the plant, please do not disintegrate. You may hit the specrum an
on the pressure test
2. Along the valve stem vertical horizontal plane to install the valve as far as possib you need other instalment please
3. When installing the valve, you should cause the medium to flow consistent with the arrow direction, do not install instea
4. When installing the valve, please open the valve completely, clean the valve and the pipeline. You should tighten thes
nis can guarantee the good seal of the padding
Th
5. In the working time, if the situation temperature changes greatly, please check and tighten the clamp nut, compact the
thus the outside leakage from the valve stem will be prevented
