性能特點(diǎn)： Performance characteristics

1、優(yōu)質(zhì)鍛件并經(jīng)固融處理的體，確保無(wú)內(nèi)外紋

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

3、閥采用結(jié)鉻鎢銅球，具有很高的高溫硬度，使其抗介質(zhì)沖蝕能力大大優(yōu)于普通針型閥

4、經(jīng)造的閥桿，柔性和強(qiáng)度不同一般，壓加工的螺紋位于填料之上，進(jìn)免了與介質(zhì)接觸，光桿部位經(jīng)精處理

不僅與填料緊密接觸，保證了密封無(wú)外漏，而且減少了開啟力矩，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、致配性優(yōu)良的柔性石墨填料，確保了高溫高壓下無(wú)外

7、執(zhí)行標(biāo)準(zhǔn)： 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

安裝維護(hù)說(shuō)明

1、產(chǎn)品出廠時(shí)已經(jīng)嚴(yán)格檢驗(yàn)，請(qǐng)勿解體，可打光譜，可試

2、閥門盡可能按閥桿垂直水平面安裝，如需其他方法安裝，河說(shuō)明

3、安裝時(shí)應(yīng)使介質(zhì)流向與閥體所示箭頭方向一致，切勿裝反

4、次使用時(shí)，須全開門，對(duì)閥門及管道進(jìn)行清洗。調(diào)整壓板螺母，確保填料處于良好密封狀態(tài)

5、運(yùn)行中，當(dāng)工況溫度變化較大（如停機(jī)維修）時(shí)，檢查并旋緊壓板螺母，壓緊填料。以防閥桿處外漏。

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
