性能特点： Performance characteristics
1、优质锻件并经固融处理的体，确保无内外纹
2、座堆焊估基硬质合金，极大地提高了高温硬度和抗介质冲蚀能力
3、阀采用结铬钨铜球，具有很高的高温硬度，使其抗介质冲蚀能力大大优于普通针型阀
4、经造的阀杆，柔性和强度不同一般，压加工的螺纹位于填料之上，进免了与介质接触，光杆部位经精处理
不仅与填料紧密接触，保证了密封无外漏，而且减少了开启力矩，门启闭时灵活自如
5、设计的中口金属密封垫，经特殊工艺调质处理，确保高温高压下的良好密封
6、致配性优良的柔性石墨填料，确保了高温高压下无外
7、执行标准： ASMI B16．34
1. The ve body has quality forging and after melts processing firmly. This can guarantee that does not have the inside and ous
ide cra
ve seat built-up welding cobalt base hard alloy, this can enhance the high temperature degree of hardness and anti-med
2、 The ium eroding ability enormously.
3. The valve petal uses the cobalt chrome tungsten steel ball. It has the very high high temperature degree of hardness. This can
cause its anti-medium eroding ablity to surpass the ordinary needle valve
4. The valve stem is forged, its flexibility and intensity different general. The trundle processed thread located at padding above
this can avoid contact with the medium The polished rod spot is processed by correct gridding. This can guarantee the close con
tact with the padding. The valve has no outside leaks. This design can also reduce the opening moment of force and the valve op
ens shuts time nimble freely.
5. The unique design mouth metal gasket is manufactured by special craft quenching treatment. This can guarantee the good se
al in the high temperature and high pressure
6. The compact fine flexible graphite padding, has guaranteed the valve has not outside leaks in the high temperature high press

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
2、阀门尽可能按阀杆垂直水平面安装，如需其他方法安装，河说明
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，检查并旋紧压板螺母，压紧填料。以防阀杆处外漏。
Installment and maintenance instruction
1. Our valves have been examined strictly when leaving the plant, please do not disintegrate. You may hit the spectrum and car
on the pressure test
2. Along the valve stem vertical horizontal plane to install the valve as far as possible, if you need other installment, please explain
3. When installing the valve, you should cause the medium to flow consistent with the arrow direction, do not install instead
4. When installing the valve, please open the valve completely, clean the valve and the pipeline. You should tighten the stem nut
This can guarantee the good seal of the padding
5. In the working time, if the situation temperature changes greatly, please check and tighten the clamp nut, compact the padding
thus the outside leakage from the valve stem will be prevented
