性能特點: Performance characteristics

1、優質鍛件并經固融處理的體,確保無內外紋

2、座堆焊估基硬質合金,極大地提高了高溫硬度和抗介質沖蝕能力

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

4、經造的閥桿,柔性和強度不同一般,壓加工的螺紋位于填料之上,進免了與介質接觸,光桿部位經精處理

不僅與填料緊密接觸,保證了密封無外漏,而且減少了開啟力矩,門啟閉時靈活自如

5、獨特設計的中口金屬密封墊,經特殊工藝調質處理,確保高溫高壓下的良好密封

6、致配性優良的柔性石墨填料,確保了高溫高壓下無外

7、執行標準: 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

ure

7. Standard: ASMI B16. 34

安裝維護說明

1、產品出廠時已經嚴格檢驗,請勿解體,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,河說明

3、安裝時應使介質流向與閥體所示箭頭方向一致,切勿裝反

4、第一次使用時,須全開門,對閥門及管道進行清洗。調整壓板螺母,確保填料處于良好密封狀態

5、運行中,當工況溫度變化較大(如停機維修)時,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
