Abstract

The utility model discloses a device for automatically cutting off and emptying water. The device is provided with a controller which comprises a controller for automatically cutting off water and a controller for automatically emptying water. A water-filling switch is connected with the controller for automatically cutting off water, the controller is connected with a water-filling electromagnetic valve which is connected with a space among a running water pipe, a water-filling pipeline, and a water-launching pipeline, and a water-emptying switch is connected with the controller for automatically emptying water. The controller is connected with a water-emptying electromagnetic valve which is connected with a space among a water tank, the water-filling pipeline, and the water-launching pipeline, and a water-emptying switch is connected with a delayer which is connected with the controller for automatically emptying water. The device can automatically control and cut off water and prevent water from running, and has the advantages of water saving, time saving, and no waiting for filling water. When the water pressure of running water is low, a check valve can be used for preventing hot water from returning from a hot water pipeline to enter a cold water pipe. A control part for automatically emptying water can empty water in the water-filling pipeline and the water-launching pipeline for avoiding freezing in winter. The utility model has the advantages that hot water left in the pipeline can be fully used and heat energy can be saved.

Description

Automatically cut off the water, automatic emptier

Technical field the utility model relates to a kind of last water of solar water heater and cuts off the water automatically and the pipeline automatic emptier.

Need see the water level indication during water on the present solar water heater of background technology, need certain hour, the somebody forgets the pass valve, causes full water and excessive, waste water resource; Bei Fang upper and lower conduit road in winter is the antifreeze emptying that needs in addition, and the emptying device of usefulness is a hydrocone type now, i.e. negative pressure of pipeline is given in human hand operated, make it water is drawn, but the people is firmly uneven in this operation, will move sometimes and just can finish several times, is inconvenient to use.

The summary of the invention the purpose of this utility model is to provide a kind of cuts off the water automatically, automatic emptier, easy to use, the conserve water resource.

The technical solution of the utility model is as follows:

This device is that a controller is arranged, and it comprises cut off the water automatically controller and automatic emptying controller; Last taps connects the controller of cutting off the water automatically, and this controller connects water solenoid valve on, and this magnetic valve connects between running water pipe and the upper and lower conduit road; The emptying switch connects automatic emptying controller, the empty magnetic valve of this controller platoon, and this magnetic valve is connected between water tank and the upper and lower conduit road, and the emptying switch connects a delayer, and this delayer connects automatic emptying controller; Power supply connects above-mentioned each device.

The said controller of cutting off the water automatically is to be placed on the positive pole that probe T one end in the water tank connects power supply, and the other end connects triode V through variable resistor W ₂Base stage, the colelctor electrode of this triode connects by capacitor C ₂, diode D ₃, relay J ₂One end of the parallel circuit of forming, another termination positive source of this parallel circuit, relay J ₃Be connected between the power positive cathode last water solenoid valve DCF ₁One end is connected in the negative pole of power supply, and the other end is through the contact of relay J _3-1, connect positive source, hand switch K ₁One termination power positive pole, an end is through resistance R ₃D ₅Connect power cathode; Said emptying controller is magnetic valve DCF ₂A termination power positive pole, its other end is through relay J ₁Contact J _1-1Connect the negative pole of power supply, as the capacitor C of delayer ₁The negative pole of a termination power, the other end is through resistance R ₂, meet triode V ₁Base stage, the collector connecting relay J of this triode ₁, the emitter stage of this triode connects the negative pole of power supply, the emptying K switch ₂One termination power positive pole, the other end is through capacitor C ₁Connect power cathode.

Above-mentioned upward water solenoid valve is a non-return valve.

Advantage of the present utility model is: the control of 1, cutting off the water automatically, prevent to metal run out, and save time in the time of conserve water, no longer full with waiting water.2, with non-return valve when tap water forces down, no longer return hot water and enter the cool water pipe from the hot water road, cause waste.3, automatic emptying control section is pressed the emptying switch and just the water on upper and lower conduit road can be discharged, and prevents from winter to freeze.4, the pipeline emptying is made full use of the last hot water of pipeline, save heat energy, use next time pipeline not have cold water, but bathing soon avoids putting a lot of cold water.Emptier was not worked when 5, this device was gone up water, if in this process water in the maloperation, then emptier quits work automatically, not spilling water outward.
