日本閥天rd-14h減壓閥詳細描述：
rd-14h valve is suitable for: oil, pressure 1.0mpa following caliber range: 20-150mm suitable temperature: 5-90 ℃ body material: cast iron valves day japan rd-14h is by adjusting the valve, the inlet pressure is reduced to the outlet pressure of a need,【敏感詞】rely on the energy of the medium itself, so that automatically maintain a stable outlet pressure valve.

rd-14h減壓閥適用于：壓力1.0mpa以下的油品，口徑范圍：20-150mm 適用溫度：5-90℃ 閥體材質(zhì)為：鑄鐵 日本閥天rd-14h減壓閥是通過調(diào)節(jié)，將進口壓力減至某一需要的出口壓力，并依靠介質(zhì)本身的能量，使出口壓力自動保持穩(wěn)定的閥門。
operation:
1, closed gate valve before the open gate valve after low pressure downstream manufacturing environment;
2, the adjusting screw counterclockwise rotation to the uppermost position (relative to the minimum outlet pressure),【敏感詞】then close the valve after the valve;
3. slowly open the gate valve to fully open before;
4. slowly turn adjustment screw clockwise, the pressure is adjusted to the desired outlet pressure (gauge pressure in the valve prevail); adjusted, the lock
nut, open the valve gate valve;
5, such as export when adjusting the pressure higher than the【敏感詞】pressure, must start from the first step to re-adjust, which can only tune from low to high pressure.
日本閥天rd-14h減壓閥操作方式：
1、關(guān)閉減壓閥前的閘閥，開啟減壓閥后的閘閥，制造下游低壓環(huán)境；
2、將調(diào)節(jié)螺釘按逆時針旋轉(zhuǎn)至最上位置（相對最低出口壓力），然后關(guān)閉減壓閥后閘閥；
3、慢慢開啟減壓閥前的閘閥至全開；
4、順時針慢慢旋轉(zhuǎn)調(diào)節(jié)螺釘，將出口壓力調(diào)至所需要的壓力（以閥后表壓為準(zhǔn)）；調(diào)整好后，將鎖緊
螺母鎖緊，打開減壓閥后閘閥；
5、如在調(diào)整時出口壓力高于設(shè)定壓力，須從第一步開始重新調(diào)整，即只能從低壓向高壓調(diào)。
