德國奧萊斯OLES進(jìn)口高加系統(tǒng)閥
【進(jìn)口高加系統(tǒng)閥】特點:
入口閥和止回閥配套使用,往高壓加熱器注水后,隨著水的壓力不斷升高,當(dāng)壓力升至一定的壓力后,借助作用于入口閥閥桿截面的壓差使閥桿向上運(yùn)動帶起閥瓣開通了進(jìn)入高壓加熱器的通道,使水進(jìn)入高壓加熱器,此時高壓加熱器投入運(yùn)行。當(dāng)高壓加熱器發(fā)生事故管系破裂,高壓加熱器內(nèi)水位超過允許值時,水位信號通過電器裝置打開快速啟閉閥,凝結(jié)水進(jìn)入入口閥上部活塞缸內(nèi),壓下活塞,推動閥瓣下移,關(guān)閉高壓加熱器的進(jìn)口,打開旁路,高壓加熱器停止運(yùn)行,整個動作時間為2秒鐘。
The inlet valve and check valve are used together. After water is injected into the high pressure heater, the pressure of water increases continuously. When the pressure rises to a certain pressure, the valve stem moves upward with the help of the pressure difference acting on the cross section of the inlet valve stem, and the valve disc opens the passage into the high pressure heater, so that the water enters the high pressure heater. At this time, the high pressure is added. The heater is put into operation. When the high-pressure heater pipe system breaks down and the water level in the high-pressure heater exceeds the allowable value, the water level signal opens the quick opening and closing valve through the electrical device, condensate water enters the piston cylinder of the upper part of the inlet valve, depresses the piston, pushes the valve disc down, closes the inlet of the high-pressure heater, opens the bypass, and the high-pressure heater stops running. The whole action time is 2 seconds.
