德国奥莱斯OLES进口高加系统阀
【进口高加系统阀】特点：
入口阀和止回阀配套使用,往高压加热器注水后，随着水的压力不断升高，当压力升至一定的压力后，借助作用于入口阀阀杆截面的压差使阀杆向上运动带起阀瓣开通了进入高压加热器的通道，使水进入高压加热器，此时高压加热器投入运行。当高压加热器发生事故管系破裂，高压加热器内水位超过允许值时，水位信号通过电器装置打开快速启闭阀，凝结水进入入口阀上部活塞缸内，压下活塞,推动阀瓣下移，关闭高压加热器的进口，打开旁路，高压加热器停止运行，整个动作时间为2秒钟。
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.
