性能特點(diǎn)
1、體、支架均鍛造后固融處理，結(jié)構(gòu)緊密無(wú)裂痕，耐高溫高壓效果*
2、閥座堆焊硬質(zhì)合金司太立6號(hào)，高溫硬度達(dá)50HRC以上
3、桿鍛造后取得了良好的抗拉強(qiáng)度和屈服強(qiáng)度，承受高溫高壓性能*
4、為司太立8號(hào)整體鍛制而成，高溫硬度達(dá)HRG58以上，與閥座形成了合適的硬度差，互相配合后具有良好的抗沖
刷、抗氣蝕性能。
5、閱體內(nèi)置閥桿導(dǎo)向座，閥門(mén)長(zhǎng)期反復(fù)開(kāi)關(guān)時(shí)，閥瓣回座率達(dá)100，保持了良好的密封性能
6變架上端置閥桿直升降裝置，閥門(mén)開(kāi)閉時(shí)，閥桿的無(wú)旋轉(zhuǎn)直升降運(yùn)動(dòng)不僅減少了對(duì)填料的磨損，而且啟閉力小，手
松
7、致密和回彈性優(yōu)良的柔性石墨填料，確保閥門(mén)不外漏
Performance characteristics
1. The body and supporting are all solid melting treated after forged. The structure is compact without any crack. High temperature
d high pressure resistant performance is excellent
The seat is buill-welded with hard alloy steel STL 6, the hardness is more than 50HRC
3. The stem has good tensile strength and yield strength after forged, High temperature and high pressure resistant performance is
excellent
4. The petal is integrally forged by STL 8, the hardness is more than 58HRC, it has suitable hardness difference with the seat
5. There is valve stem guide seat in the body, after the valve is opened and closed repeatedly for a long time, the retum rate of the
petal is 99%. The sealing performance is good.
6. Stem straight lifting device is on the top of the supporting. when the valve is opened and closed, non rotating lifting movement of
the stem can reduce the wear of the filler. The opening and closing force of the valve is small
7. Flexible graphite filler is compact and its elastic resilience is excellent, this can guarantee the vale has no extemal leakage

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，可試壓
2、閥門(mén)盡可能按閥桿垂直水平面安裝，如需其他方法安裝，請(qǐng)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(kāi)閥門(mén)，對(duì)閥門(mén)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)，襝查并旋緊壓板螺母，壓緊填料。以防閥桿處外溫
Installment and maintenance instructi
1. Our valves have been examined strictly when leave the plant, please do not disintegrate. You may hit the specrum an
on the pressure test
2. Along the valve stem vertical horizontal plane to install the valve as far as possib you need other instalment please
3. When installing the valve, you should cause the medium to flow consistent with the arrow direction, do not install instea
4. When installing the valve, please open the valve completely, clean the valve and the pipeline. You should tighten thes
nis can guarantee the good seal of the padding
Th
5. In the working time, if the situation temperature changes greatly, please check and tighten the clamp nut, compact the
thus the outside leakage from the valve stem will be prevented
