Abstract

The utility model discloses a campus timing water supply device, which belongs to the electric appliance control equipment, in particular to water supply control equipment. The campus timing water supply device comprises a water supply main pipe, a stop valve and a water use pipe network. The utility model is characterized in that a magnetic valve which is controlled by a programmable timer is mounted behind the stop valve of the water supply main pipe. The timer is set to open the magnetic valve to achieve water supply when classes finish and close the magnetic valve to stop water supply when classes begin through utilizing the programmable timer according to teaching time, and the circulation achieves a through pipeline when students use water, and the water supply main pipe is closed by the magnetic valve when classes begin, even if water taps are not closed or are not completely closed, water can not continuously flow, compared with manually-opening and closeting the main stop valve, the campus timing water supply device saves time and saves labor, which can save a great amount of precious water.

Description

Campus Timing water supply device

Technical field

The utility model belongs to electrical apparatus control equipment, and control appliance particularly supplies water.

Background technology

There is the particularity of its water in the student of the school zone of imparting knowledge to students, promptly following class hour is concentrated water, to water not of last class hour,, there is the people not notice that switch is wasted because of untimely controlled valve causes big water gaging especially as toilet flushing water especially unavoidably though taps is arranged in the place of water.The school that for this reason has adopts the artificial total stop valve that opens and closes supply line to avoid waste waste of manpower like this.

The utility model content

In order to overcome the artificial deficiency that opens and closes total stop valve of existing needs, the purpose of this utility model provides a kind of campus Timing water supply device, and this campus Timing water supply device adopts programmable timer control supply line.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of campus Timing water supply device, comprise water main, stop valve, water pipe network, and it is characterized in that: the electromagnetic valve that programmable timer control is housed behind the stop valve of water inlet manifold.

The circuit structure of the electromagnetic valve of described programmable timer control is the input that power line is connected to programmable logic controller, and the output of this timer is connecting electromagnetic valve.

The output of described timer is connecting relay, and relay contact connects power line and electromagnetic valve respectively.

The beneficial effects of the utility model are to use programmable timer, and arrangement is provided with timer and realize supplies water opening electromagnetic valve following class hour according to instructional blocks of time, stop to supply water to closing electromagnetic valve last class hour, pipeline was logical when so circulation realized student's water, last class hour closed electromagnetic valve water main, even not closing or be not closed completely, some water tap can not continue flowing water yet, the total stop valve of artificial switching is time saving and energy saving, can save the water of billow preciousness.
