Embodiment

The contrast accompanying drawing carries out detailed elaboration with the combination preferred embodiment to the utility model below.

As shown in Figure 2, the overflow warning box comprises casing 1, bleeder pipe 3, liquid level warning switch (selecting float switch 4 in this example for use) and U trap 5, and the top of casing 1 is provided with liquid injection port 2; Bleeder pipe 3 places in the casing 1, and the liquid outlet 31 of bleeder pipe 3 stretches out the bottom of casing 1, and the inlet 32 of bleeder pipe 3 is arranged on the liquid level place that releases of casing; The setting that interlaces of the inlet 32 of liquid injection port 2 and bleeder pipe, float switch 4 is arranged on the warning liquid level place of casing, the U type pipe that U trap 5 is uneven in length for two ends; Be inverted in the casing 1; The long end of U trap 5 is provided with liquid outlet 51, stretches out casing 1 bottom, and the short end of U trap 5 is provided with inlet 52; The summit of siphonal bend is higher than the warning liquid level at float switch 4 places, and is lower than the liquid level of releasing at inlet 32 places of bleeder pipe 3.

The caliber of U trap 5 is less than the caliber of bleeder pipe 3; To guarantee that the siphon mass rate of emission is not more than the speed of releasing of bleeder pipe; But general siphonal mass rate of emission is designed to about 10 minutes the liquid in the emptying casing and is advisable; The caliber of bleeder pipe 3 to guarantee in casing, forming liquid level, reaches the purpose of warning more than or equal to the caliber of liquid injection port 2.

If the inlet of liquid injection port and bleeder pipe faces, liquid can directly flow to the inlet of bleeder pipe from liquid injection port, do not have the warning effect; So when design; The inlet that guarantees liquid injection port and bleeder pipe does not face, and is designed to the bottom of liquid injection port 2 towards casing 1 in this example, and it is (certain towards the side of casing 1 that the inlet 32 of bleeder pipe 3 bends towards a side; In other embodiments; Different designs can also be arranged, as long as can guarantee that liquid that can not from directly flow to the inlet of bleeder pipe from liquid injection port, gets final product the liquid level that can form rising in the casing).
