产品简介

rginginstrumentvalve性能特点Performancecharacteristics1、优质件并经固融处理的阀体，确保无内外裂纹

详细介绍

rging instrument valve

性能特点 Performance characteristics

1、优质件并经固融处理的阀体，确保无内外裂纹。锻件符合JB9826－1999的规定

2、阀座堆焊钴基硬质合金，极大地提高了高温硬度和抗介质冲蚀能力

共抗介质冲使能力大大优于普通针型

、采用进口结经钢球，具有很高的高温度，使

经锻造的阀杆，柔性和强度不同一般，滚压加工的螺敏位于填料之上，避免了与介质接触，光杆部位经精隆处理

不仅与填料紧密接触，保证了密封无外漏，而且滅少了开启力矩，阀门启闭时灵活自如

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、致密性优良的柔性石填料，确保了高温高压下无外漏

7、执行标准： ASMI B16．34

1. The body is sold melting treated after forged. The valve does not have inside and outside cracks. The forging conforms to JB

9626-1999

2. The seat is uilt-welded with cobalt base hard alloy, this can enhance the high temperature hardness and anti-erosion peror

-mance greatiy

3. The petal i s the Co-cr-w steel ball. It has very nigh high temperature hardness. Its anti-erosion is better than the ordinary

needle valves

4. The stem is rged, its flexibility and intensity Is good. Roing processed thread located above the ller, this can avold contact

with the medium directly, The polished rod spot is processed by correct gridding. This can guarantee the close contact with the

filler, The valve has no outside leaks. This design can also reduce the open torque and the valve can be opened and closed eas

5. The unique design mouth metal gasket is manufactured by special craft quenching treatment. This can guarantee the sealing

in the high temperature and high pressure is good

6. Compactness of the flexible graphite filler is very good, the valve has not outside leaks in the high temperature and high press-ure
