rging instrument valve

性能特點(diǎn) Performance characteristics

1、優(yōu)質(zhì)件并經(jīng)固融處理的閥體，確保無內(nèi)外裂紋。鍛件符合JB9826－1999的規(guī)定

2、閥座堆焊鈷基硬質(zhì)合金，極大地提高了高溫硬度和抗介質(zhì)沖蝕能力

共抗介質(zhì)沖使能力大大優(yōu)于普通針型

、采用進(jìn)口結(jié)經(jīng)鋼球，具有很高的高溫度，使

經(jīng)鍛造的閥桿，柔性和強(qiáng)度不同一般，滾壓加工的螺敏位于填料之上，避免了與介質(zhì)接觸，光桿部位經(jīng)精隆處理

不僅與填料緊密接觸，保證了密封無外漏，而且滅少了開啟力矩，閥門啟閉時(shí)靈活自如

5、設(shè)計(jì)的中口金屬密封墊，經(jīng)特殊工藝調(diào)質(zhì)處理，確保高溫高壓下的良好密封

6、致密性優(yōu)良的柔性石填料，確保了高溫高壓下無外漏

7、執(zhí)行標(biāo)準(zhǔn)： 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
