Novel anti-overflow valve
The invention discloses a novel anti-overflow valve. The novel anti-overflow valve comprises a anti-overflow valve shell body fixing barrel arranged on a vacuum tank in a sealed mode, an anti-overflowvalve shell body arranged on the anti-overflow valve shell body fixing barrel, a metal floating ball arranged in the anti-overflow valve shell body and a proximity switch arranged in the position, located right above the metal floating ball, in the anti-overflow valve shell body. According to the novel anti-overflow valve, the proximity switch is additionally arranged on a conventional anti-overflow valve, the liquid level rises to the front of the position where the floating ball seals a pipeline, and the metal floating ball can trigger the proximity switch firstly, so that an electric signal is transmitted to a control system to enable an alarm lamp and an alarm to send out a flashing signal or a voice control signal, an operator is reminded to close a vacuum pump in time, or a circuitis directly controlled to automatically close the vacuum pump, the vacuum pump is prevented from being damaged due to the fact that the time that the floating ball blocks the vacuum pipeline is tool long, or the vacuum pump is prevented from being damaged due to dirt overflowing caused by sealing failure, and the operator is liberated without paying attention to the liquid level height of an excrement viewing pipe all the time.
本发明公开了一种新型防溢阀，包括密封设置在真空罐上的防溢阀壳体固定筒、安装在所述防溢阀壳体固定筒上的防溢阀壳体、设置在所述防溢阀壳体内的金属浮球以及在所述防溢阀壳体内并位于金属浮球正上方安装有接近开关。本申请中在常规防溢阀上增加接近开关，当液面上升到浮球封死管路前，所述金属浮球会先触动接近开关，从而传送给控制系统，进行报警灯和报警器以闪灯信号或声控信号，提醒操作人员及时关闭真空泵，或者直接控制电路自动关闭真空泵，从而防止浮球堵死真空管路时间过长而损坏真空泵，又或防止密封失效导致污物漫泵而损坏真空泵，并将操作人员解放出来，不用时刻关注视粪管液位高度。
