進口高溫蒸汽減壓閥安裝說明： 

1、高溫蒸汽減壓閥安裝前必須對管路系統(tǒng)進行沖洗清理。以防焊渣，氧化皮等贓物流入閥內(nèi)，影響閥門正常工作。

2、高溫蒸汽減壓閥應(yīng)安裝在便于操作和維修的地方，并且必須直立安裝在水平管道上，應(yīng)注意使管路中介質(zhì)的流向與閥體上箭頭所示方向一致，切勿反裝。

3、高溫蒸汽減壓閥在安裝使用時，應(yīng)把旁通管道的截止閥打開，排除管路中的冷凝水和汽水的混合物，以防減壓閥開啟時產(chǎn)生水圾現(xiàn)象損壞減壓閥，當無異?，F(xiàn)象后，按順時針方向緩慢旋轉(zhuǎn)調(diào)節(jié)螺釘，將出口壓力調(diào)至所需的壓力(以閥后表壓為準)，調(diào)整后，將鎖緊螺母背緊，擰上防護罩。

4、高溫蒸汽減壓閥前應(yīng)安裝過濾器，以防介質(zhì)中的雜物進入減壓閥，影響其性能。

5、安裝的減壓閥前后應(yīng)有一段直管，閥前的直管長度約為600毫米，閥后的直管長度約為1000毫米。

6、高溫蒸汽減壓閥要求進出口壓差必須≥0.2Mpa。

7、高溫蒸汽減壓閥的管網(wǎng)必須裝安全閥，以防減壓閥失效壓力升高造成系統(tǒng)或者設(shè)備的破壞。

進口高溫蒸汽減壓閥產(chǎn)品簡介：

德國洛克《DE LOCKE》進口高溫蒸汽減壓閥，High temperature steam reducing valve，是指用于高溫熱蒸汽或者高溫飽和蒸汽場合，比如蒸汽溫度為200℃，蒸汽溫度250℃，蒸汽溫度300℃，蒸汽溫度400℃，蒸汽溫度450℃的蒸汽管道，能將閥前的蒸汽壓力減到所需要的出口壓力，并將壓力穩(wěn)定在所需要的壓力值的減壓閥，屬于可調(diào)式先導(dǎo)活塞式減壓閥。由主閥和導(dǎo)閥兩部分組成。主閥主要由閥座、閥閥盤、活塞、缸套、彈簧等零件組成。導(dǎo)閥主要由閥座、閥瓣、膜片、彈簧、調(diào)節(jié)彈簧等零件組成。通過調(diào)節(jié)調(diào)節(jié)彈簧壓力設(shè)定出口壓力，利用膜片傳感出口壓力變化，通過導(dǎo)閥啟閉驅(qū)動活塞調(diào)節(jié)主閥節(jié)流部位過流面積的大小，實現(xiàn)減壓穩(wěn)壓功能。進口高溫蒸汽減壓閥主要用于高溫蒸汽管路，起到減壓穩(wěn)壓作用。  

Brief introduction of imported high temperature steam pressure reducing valve:
High temperature steam reducing valve imported from German Locke Valve is a kind of pressure reducing valve, which can reduce the steam pressure in front of the valve to the required outlet pressure and stabilize the pressure at the required pressure value. It is an adjustable pilot piston type pressure reducing valve, which is used for high-temperature hot steam or high-temperature saturated steam occasions, such as steam pipe with steam temperature of 200 ℃, steam temperature of 250 ℃, steam temperature of 300 ℃, steam temperature of 400 ℃ and steam temperature of 450 ℃ Pressure valve. It consists of main valve and pilot valve. The main valve is mainly composed of valve seat, valve disc, piston, cylinder liner, spring and other parts. Pilot valve is mainly composed of valve seat, disc, diaphragm, spring, adjusting spring and other parts. The outlet pressure is set by adjusting the spring pressure. The diaphragm is used to sense the change of outlet pressure. The pilot valve is opened and closed to drive the piston to adjust the flow area of the throttle part of the main valve to realize the function of pressure reduction and stabilization. The imported high temperature steam pressure reducing valve is mainly used for high temperature steam pipeline to reduce pressure and stabilize pressure.
