                                    給水止回閥容易產生哪些故障?如何消除?

                                    [ 2013-12-04 ]
                                    給水止回閥容易產生哪些故障?如何消除?
                                    答:給水止回閥常見的故障有:
                                    (1)倒汽倒水;
                                    (2)閥心(或活門)不能開啟。
                                    產生上述故障的原因及其排除方法,見表:

                                    故障 原因 排除方法
                                    倒汽倒水 (1)閥芯與閥座接觸面有傷痕或磨損
                                    (2)閥芯與閥座接觸面之間有污垢
                                    (1)檢修或研磨接觸面
                                    (2)消除污垢
                                    閥心(或活門)不能開啟 (1)閥芯與閥座接觸面被水垢黏住
                                    (2)閥心(或活門)轉軸被銹住
                                    (1)消除污垢防止黏住
                                    (2)打磨鐵銹,使之活動
