产品详情

性能特点: Performance characteristcs:

1、优质锻件井经固融处理的阀体,确保无内外裂敏

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

3、阅果用钻铬钨钢球,具有很高的高温硬度,使其抗介质中蚀能力大大忧于通针型,

4、经锻造的阀杆,柔性和强度一同一般,滚压加工的螺纹位于填料之上,温免了与介质接,光杆部位经精处理

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

5、独特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對

6、致密性优良的柔性石墨填料,确保了高温高压下无外温

7、执行标准:ASM1B16.34

1. The valve body has quality forging and after melts processing (rmly. This can guarantee that does not have the inside and outs

de cracks

2. The valve seat built-up welding cobalt base hard alloy, this can enhance the high temperature degree of hardness and anti-med

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 an-medium eroding ability to surpass the ordinary needle valve

4。 The va e 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
