二、進(jìn)口減壓閥安裝和維護(hù):

1、減壓閥為了操作和維護(hù)方便，該閥一般直立安裝在水平管道上。

2、減壓閥安裝時應(yīng)注意使管路中介質(zhì)的流向與閥休上所示箭頭的方向一致。

3、減壓閥為了防止閥后壓力超壓，應(yīng)在離閥出口不少于4M處安裝一個減壓閥。

1. For the convenience of operation and maintenance, the pressure reducing valve is generally installed vertically on the horizontal pipeline.

2. When installing the pressure reducing valve, pay attention to make the flow direction of the medium in the pipeline consistent with the direction of the arrow shown on the valve seat.

3. In order to prevent overpressure behind the valve, a pressure reducing valve shall be installed at least 4m away from the valve outlet.

四、進(jìn)口減壓閥基本性能：

（1） 調(diào)壓范圍：它是指減壓閥輸出壓力P2的可調(diào)范圍，在此范圍內(nèi)要求達(dá)到規(guī)定的精度。調(diào)壓范圍主要與調(diào)壓彈簧的剛度有關(guān)。

（2） 壓力特性：它是指流量g為定值時，因輸入壓力波動而引起輸出壓力波動的特性。輸出壓力波動越小，減壓閥的特性越好。輸出壓力必須低于輸入壓力—定值才基本上不隨輸入壓力變化而變化。

（3） 流量特性：它是指輸入壓力—定時，輸出壓力隨輸出流量g的變化而變化的持性。當(dāng)流量g發(fā)生變化時，輸出壓力的變化越小越好。一般輸出壓力越低，它隨輸出流量的變化波動就越小。

(1) Pressure regulating range: it refers to the adjustable range of the output pressure P2 of the pressure reducing valve, within which the specified accuracy is required. The pressure regulating range is mainly related to the rigidity of the pressure regulating spring.

(2) Pressure characteristic: it refers to the characteristic of output pressure fluctuation caused by input pressure fluctuation when flow G is constant. The smaller the output pressure fluctuation, the better the characteristics of the pressure reducing valve. The output pressure must be lower than the input pressure - set value to basically not change with the input pressure.

(3) Flow characteristics: it refers to the input pressure timing, the output pressure changes with the change of output flow G. When the flow rate G changes, the smaller the change of the output pressure is, the better. Generally, the lower the output pressure is, the smaller its fluctuation with the change of output flow.
