How to save water in the toilet of school teaching building

It is a series of products developed according to the characteristics of grooved toilets. Based on infrared induction technology, it is convenient and hygienic, safe and energy-saving, with simple design ideas.

Grooved toilets are large, and urinal infrared induction water saver installation schematic atlas

is highly integrated, user-friendly, stable in performance, economical and durable, with simple modification by users, small in investment and quick in effect. The actual inspection of each unit shows that the average water saving rate of HP24-S2, which is suitable for automatic flushing of toilet urinals in trench toilets, is 85%? Above; HP24-S1, which is suitable for automatic flushing of urinals in grooved toilets, can miraculously achieve an average water saving rate of 95% by adopting the new locking time technology. Above. ?

The grooved toilet urinal infrared sensor water-saving device adopts a unique design of uninterrupted scanning, automatic superposition of human body signals and additional delay after the signals disappear, that is, when no one is using the squatting position, the infrared sensor detector is on standby and does not supply power to the electromagnetic valve, and the electromagnetic valve is normally closed without running water. When someone enters the squatting position of the stool grille, the infrared detector captures the signals and supplies power to the electromagnetic valve, and at the same time, it continuously scans the human body signals to confirm that the human body signals have not disappeared. Power is continuously supplied to the electromagnetic valve, and the electromagnetic valve continuously discharges water into the water tank; after the person goes to the toilet, the sensor detector leaves the squatting position to confirm that the human body signal disappears, and the time delay is increased by 1.5-2 minutes, so that the electromagnetic valve is cut off and the infrared sensor detector returns to the standby induction state. After the water flow is adjusted, squatting for two or three times is interrupted, and the siphon water tank is filled with water and a box of water is flushed into the groove (two or three people are waiting for the same time, that is, two or three people coming at the same time are regarded as a human body signal).

the delay time can also be adjusted as required (the adjustment range is about 1 seconds to 4 seconds, and there is time to tune the knob outside). Accurate sensing area, no false alarm: the infrared sensing detector is small in size, flexible in installation, and has internal and external angle adjustment fittings, which can accurately locate the sensing area according to environmental needs and avoid invalid and false start.

zero pressure start: the solenoid valve is a direct-acting valve, which can be started and closed normally without water pressure in the pipeline, thus solving the problem of uniform application in various complex environments, and can work normally even if the water pressure is low.

Because the controller does not drain water when no one is in the toilet, and squats for two or three times intermittently, the siphon water tank fills up with water and flushes a box of water into the ditch, which resolutely puts an end to the ineffective drain when no one is in the toilet, and at the same time can flush the toilet efficiently and timely, thus achieving the organic combination of sanitation and water saving. According to the different frequency of toilet urinal, the water-saving efficiency is different. The lower the frequency of toilet use, the higher the water-saving efficiency, and the higher the frequency of use, the slightly lower the water-saving efficiency. The actual comprehensive average water saving rate exceeds 8%.
