Description

Domestic water supply automatic controller

The utility model relates to a kind of water pipeline and controls cut-off valve automatically.

Owing to a variety of causes, in disconnected when some local tap water of China, frequent generation water supply, time, continue and Timing water supply phenomenon, particularly summer at present, and this phenomenon is even more serious.Bring very big inconvenience to people's life.People need a kind of volume little, inexpensive, do not need the people to guard, and can automatically water be piled water container, the valve of closing automatically again for tap water the time.

There is the water valve of automatic control function that two kinds of float-ball type valve and solenoid valves are arranged now.It is the float corresponding displacement owing to fluctuation in stage produces that is mounted in the container that ball float cuts down, by shouldering bar drive valve opening or closing.This valve body is long-pending big, is subjected to the use occasion position limit, can not install and use flexibly.It is control means that the electromagnetic type internally piloted valve adopts A.C. contactor, and as the power that opens and closes valve, this valve big energy-consuming, volume are big, influenced by power failure with Ac with electromagnet.

The purpose of this utility model is to provide a kind of supply and automatically controlling water device.With electronics with mechanical technique is ingenious combines, use dryelement cell (3V) power supply, with power supply, valve, machinery, electronic control system are installed on the base plate, and water-level probe is connected with control section with flexible circuit conductor.The mode that adopts the action of control electromagnet to remove the valve self-locking realizes the purpose of automatic-closing valve.

Describe in detail below in conjunction with accompanying drawing: such as Fig. 1,2,3,4, the one side of base plate 1 is established Battery folder, mechanical controller structure and electronic controller are arranged. Another side is equipped with by-pass valve control. Wherein the support 3 of mechanical controller structure and support 6 are adjacent and be separately fixed on the base plate 1. Support 3 connects bar 4 processed by bearing pin 28, between an end of control lever 4 and the base plate 1 support spring 27 is arranged, and the other end has concave station, and lodge is on the boss 20 of valve rod 5. Gag lever post 13 on spring 21 and the lodge limited location switch 12 is arranged between the boss 20 on the valve rod 5 and the base plate 1. Be connected with electromagnet 8 and armature 9 on the support 6, spacer pin 7 passes the hole on armature 9 and the support 6, is installed on the support 6 and by a bayonet lock and is set with tension spring. Hand-reset device 10 is fixed on the base plate 1, and is set with reset key 15, and release link 11 1 ends are connected with reset key 15, and the other end has slope mouth and armature 9 lodges down. Electronic controller is installed on the base plate, and circuit as shown in Figure 5. By resistance R 1 capacitor C 1, C2, the oscillation boosting rectification circuit that transistor BG2 and transformer B crystal diode BG4 form, resistance R 4 capacitor C 3 controllable silicon BG3 form the energy storage executive circuit, little circuits for triggering and limit switch 12 that resistance R 2, R3 controllable silicon BG1 form, the compositions such as power supply. Adopt two joint 1.5V dry cells as working power, by battery folder 2 fixing, connecting electronic controllers. Probe 30 sheet metals by two mutual insulatings form, also can be with other such as any geometry shapes such as garden, ball, rods, and the one end should have the good conductive surface that is no less than 2 mm lengths, the most handy copper. The other end has respectively the flexible circuit conductor of mutual insulating to link to each other with electronic controller input element R2, R3. Electronic controller output termination electromagnet coil CT. The another side of base plate 1 is equipped with the flange 22 of control valve, and flange 22 other ends link to each other with valve body 24, and lining 29, guide pin bushing 23 that valve rod 5 passes in base plate 1 and the valve body 24 insert valve body, and valve core 25 is equipped with in valve rod 5 ends, and the other end of valve body is equipped with bushing 26.

Embodiment: when using family expenses supply and automatically controlling water device, at first bushing 26 and water supply line are connected, water outlet connects the desire water container, and probe 30 places the water container desired location.Press lower valve rod 5, make valve core 25 open intake tunnel.At this moment the boss on the valve rod 5 is depressed position-limited lever 13 and Returnning spring 21; Position-limited lever 13 is connected the limit switch action, makes electronic controller be in the preparation work state; Controlling rod 4 under the effect of rearward end support spring lodge in the upper-end surface of boss 20; Position limit pin 7 props up controlling rod 4 rearward end lower edges under spring action, pin valve rod 5, makes it to be in depressed state, and water promptly flows out from valve continuously.When the water container liquid level reaches desired location, probe 30 contacts with water, makes little trigger circuit triggers, controllable silicon BG1 conducting makes transistor BG2 starting of oscillation, and diode BG4 rectification is passed through in output after transformer B transformation, give capacitor C3 charging, when voltage reaches rating value (30V) but i.e. triggering silicon BG3 conducting, make electromagnet inhale moving armature 9 actions, pulling position limit pin 7 returns, discharge the locking of controlling rod 4 rearward end, valve rod 5 resets by Returnning spring 21, drives valve core 25 sealing water flow passage, throttle down; Position-limited lever 13 resets limit switch 12 is disconnected, and electronic control circuit is in off position.When interim releasing is controlled cut-off valve automatically as need, can use hand reset device 10, press the reset key 15 of hand reset device 10, the release link 11 that is connected with reset key 15 promote armature 9 towards the downslope mouth to the electromagnet direction, make it remove 4 lockings of 7 pairs of controlling rods of position limit pin, valve rod 5 is resetted close the valve control valve.

To valve closing will be arranged from the probe contact water surface one lag time, present embodiment is 1～2 second, and the probe desired location is lower than predetermined control water line.
