安装壁流式真空自动脱气装置水循环系统安装方法和运行控制方法  Installation method and operation control method for installing water circulation system of wall flow type vacuum automatic deaeration device
首先关闭水泵，打开密闭容器 10上部的壁流喷射进水口电磁阀，系统水便会通过流量控 制阀进入密闭容器， 这时流量控制阀随着设定的排气频率而控制进入密闭容器的水流量。 当 密闭容器内水达到设定的最高水位时， 自动关闭进水阀， 而自动打开水泵， 密闭容器内的水 通过另一个流量控制阔便会进入采暖系统或空调系统。 当密闭容器内水位降低到设定的低水 位时， 水泵则自动关闭， 这时在水位最高与最低的空间形成瞬时真空。 与此同时密闭容器上 部的壁流喷射进水口电磁阀又自动打开使系统水又进入密闭容器内的真空部位， 由于进入密 闭容器内水的压力急剧降低必将引起水中溶解的空气释放出来。 这一过程由于将水经过壁流 喷射而使水、 气加速分离， 这个过程使气体从密闭容器中心向上不断聚集， 并上升到密闭容 器顶而排出密闭容器达到脱气的目的。 密闭容器中气体的排除是通过排气阀自动排气而得以 实现。  First, the water pump is turned off, and the wall flow injection inlet solenoid valve of the upper part of the closed container 10 is opened, and the system water enters the closed container through the flow control valve. At this time, the flow control valve controls the water entering the closed container according to the set exhaust frequency. flow. When the water in the closed container reaches the set maximum water level, the inlet valve is automatically closed, and the water pump is automatically turned on, and the water in the closed container passes through another flow control to enter the heating system or the air conditioning system. When the water level in the closed container drops to the set low water level, the water pump automatically shuts down, at which point a momentary vacuum is created in the highest and lowest water level. At the same time, the wall flow injection inlet solenoid valve in the upper part of the closed container is automatically opened to allow the system water to enter the vacuum portion of the closed container. The pressure of the water entering the closed container is drastically reduced, which will cause the dissolved air in the water to be released. This process accelerates the separation of water and gas by spraying water through the wall. This process causes the gas to continuously collect upward from the center of the closed container and rise to the top of the closed container to discharge the closed container for degassing. The elimination of gas in the closed vessel is achieved by automatic venting through the vent valve.
