Abstract

The utility model relates to a water saving device, which can automatically close a valve when water leakage of pipelines and devices happens. An electrically operated valve in the prior art is not reasonable in structural design, narrow in application range and incapable of meeting the requirements for automatically closing the valve when the water leakage happens. A water flow switch is additionally arranged at the back of the electrically operated valve, a liquid crystal display screen is used for setting normal water time, an integrated circuit controller is installed in a machine body, and a dry battery serves as a power source. Therefore, the stop valve capable of automatically alarming during the water leakage has the advantages of small size, light weight, low production cost, convenience in installation and maintenance, stable performance, wide application range, long service life and the like.

Description

Automatic warning cut-off valve leaks

The utility model relates to a kind of water saving fixtures, and it is applicable to when whole piece pipeline and various leaks with drainage facility and reports to the police automatically that cut-off valve also notifies the owner in time to handle, in order to avoid cause unnecessary waste and economic loss.

Mortor operated valve of the prior art is as shown in Figure 1; Owing to receive its structural limitations; In actual use; Have following defective: it can only open or close electric valve with hand push button, arbitraryly according to actual needs in the time of can not leaking required requirement is set opens or closes valve and reports to the police automatically and cut off the water supply.

The purpose of the utility model is: in order to fill up deficiency in the prior art, and a kind of reasonable in design, automatic warning cut-off valve that leaks that using scope is wide is provided, is generalized to family widely; The hotel, enterprise and institution ... In go, stop to run; Emit; Drip, leak, thereby reach water-saving purpose.

The purpose that the utility model proposed can realize through following technological scheme: when water passes through this cut-off valve in the direction of arrows; The automatic opening power of water switch; Open buzzer warning at the normal water of setting after time through controller, in time handle and surpass time of fire alarming, just start mortor operated valve; Cut off rapidly the whole piece pipeline and, notify managerial department or owner in the very first time, to obtain reparation simultaneously with the water of drainage facility.

Description of drawings is following:

Fig. 1 is a mortor operated valve structural representation in the existing technology.

Fig. 2 is the utility model structural representation.

Fig. 3 is the water switch schematic representation of the utility model.

Following the utility model combines accompanying drawing, and comes further to detail through embodiment.

Referring to Fig. 2; This automatic warning cut-off valve that leaks mainly is made up of controller I, pipe jointer II: have among the controller I; The

timer

4,5,6 that buzzer 1, motor 2, time-delay are left, power-supply battery 7, manually open valve button 8, manually close valve button 9, signal output terminal 10, all inserting intergrated circuit 3 becomes the complete control system of a cover; Have among the pipe jointer II, water switch III comes switch power, and valve IV cuts off pipeline; Unscrew locking nut V, extract attachment plug VI controller I, pipe jointer II are separated, reach dismountable purpose.

Referring to Fig. 3, the water switch III in this automatic stop valve that leaks is a sensed system, and sensitivity transfers 12 to regulate tooth bar

13, dry reed-pipe or Hall element 14, magnet 15, lodicule 16, holddown spring 17, switch output line 18 are formed.

Referring to Fig. 2, Fig. 3, wholely leak automatic warning cut-off valve in use, current Parallel to the flow direction 11 is pushed lodicule 16 open when pipe jointer II flows through; Lodicule 16 drives magnet 15 and touches dry reed-pipe 14, dry reed-pipe 14 closures, energized battery 7; Intergrated circuit 3 gets into working state; Delay switch is started working to setting the

timer

4,5,6 that ensures the normal water time, in case surpass the set time control range, buzzer 1 is reported to the police; Time of fire alarming length is solidified in IC design; If in curing time, stop water, water switch is in the adhesive that the effect lower magnet 15 of spring 17 breaks off dry reed-pipe 14, cuts off the electricity supply automatically and returns to reset condition.If time of fire alarming surpasses intergrated circuit and solidified the design time limit, prove pipeline or leaking with drainage facility; Buzzer 1 stops to report to the police; Start mortor operated valve motor 2 immediately, automatic-closing valve IV cuts off the water supply, and signal output apparatus 10 sends the relevant managerial department of signalisation simultaneously or the owner repairs as early as possible; Repair the back with button 8 manual unlocking electric valve IV, promptly recovered normal water.

This device is provided with hand push button 8 and opens electric valve, and hand push button 9 is closed the manual operating device of electric valve.

This device is provided with signal output apparatus 10, and the relevant personnel and department in time obtain information.

This device also is provided with the split function, as long as unscrew locking nut V, takes out signal attachment plug VI, and controller I just can unload down from pipe jointer II and be divided into two bodies.

The utlity model has following advantage: 1. reasonable in design, volume is little, in light weight, cost is low; 2. easy for installation, reliable, long service life; 3. using scope is wide, is not limited to water, and when all escape of liquid, all can use; 4. do not receive the limitation of power supply.

The utility model also has following defective: water clock (promptly leaking on a small quantity) phenomenon water switch III is difficult to start.
