Abstract
The utility model relates to a water-out prevention automatic control water valve which consists of a power supply circuit, a monitoring circuit, a control circuit, two flow sensors and an electric butterfly valve. The electric butterfly valve and the two flow sensors are arranged on a water supply pipeline without a branch water outlet along the water flow direction sequentially. After being arranged, the device is in a normally-open state. When water flows in the pipeline, the two flow sensors send signals; the monitoring circuit receives the signals sent by the flow sensors and compares the signals; and if the monitoring circuit observes that the downstream flow is lower than the upstream flow, which shows that the water pipe can be broken, a driving signal is sent so that the electric butterfly valve is closed and the water supply pipeline is automatically switched off. The water-out prevention automatic control water valve has the characteristics that the water-out prevention automatic control water valve is convenient to install, is reliable to work, is flexible to control, has low cost and the like. The water-out prevention automatic control water valve can be widely used as a water valve of a main pipeline or a branch pipeline for controlling water supply.
Description
Technical field
The utility model is controlled water valve automatically for anti-water logging, belongs to the detection and the automatic control technology field of valve.
Background technique
In daily life, we often see that water pipe digs the disconnected fountain that forms because of explosion or by construction party, water overflows Kingsoft sometimes, water is with the resident family that flows to Stall or the retail shop of mercilessness, indoor clothing, furniture, electrical equipment, commodity etc. are immersed in water and produce great loss, and precious water resource is also by a large amount of wastes.Therefore, development is a kind of in the water pipe explosion or dug the anti-water logging that can close automatically when disconnected to control water valve automatically be very necessary.Especially to the conserve water resource, more apparent its necessity.
Summary of the invention
In view of existing problem in the actual life, the purpose of this utility model is that development is a kind of when the water pipe explosion or dug when breaking, can close the device of water-delivery valve automatically, the utlity model has easy for installation, reliable operation, control sensitivity, characteristics such as with low cost, can be widely used in controlling the total pipeline of water supply or the water valve of branch pipe(tube).
The technical solution of the utility model is such: anti-water logging is controlled water valve automatically and is made up of power circuit, supervisory circuit, control circuit, two flow transducers, electric butterfly valves.Electric butterfly valve, two flow transducers are contained in successively along water (flow) direction on the water supply line that does not branch out the mouth of a river, do not have distance limit between two flow transducers, and this device is in normally open after installing.When having water to flow in the pipeline, two flow transducers send signal, and supervisory circuit receives that flow transducer sends signal and compares, as find downstream flow less than upstream flowrate, illustrate that water pipe breaks, and sends drive signal, electric butterfly valve cuts out, cut off supply channel automatically.
The utility model beneficial effect compared with the prior art is: can or be dug and close water valve automatically when disconnected in the water pipe explosion, both prevent the property loss that causes because of water logging, save precious water resource again.
Description of drawings
The utility model has four accompanying drawings, wherein:
Fig. 1 is that water valve water route structural drawing is controlled in anti-water logging automatically.
Fig. 2 is supervisory circuit figure.
Fig. 3 is control circuit figure.
Fig. 4 is a power circuit diagram.
Among the figure: 1-water pipe 2-arrow is represented the water (flow) direction 3-electric butterfly valve 4-first flow meter 5-second flowmeter 6-branch water pipe
Embodiment
The water route connection is seen shown in Figure 1, the water intake of the water outlet of electric butterfly valve 3 and first flow meter 4 is tightly connected, the water intake of second flowmeter 5 is tightly connected by the water outlet of water pipe and first flow meter 4, and the water pipe between the first flow meter 4 and second flowmeter 5 does not branch out the mouth of a river.

Concrete working principle is as follows:
I
1Be the electrical signal of 4～20mA of second flowmeter, 5 outputs, convert corresponding 1～5V voltage signal to through R1 resistance.Level and smooth by R3, C1, export through the IC1 follower.IC3, IC4 and peripheral R4～R8, C3 constitute peak holding circuit, note peak rate of flow signal within a certain period of time, by the 5 pin output of IC3.
I
2Be the electrical signal of 4～20mA of first flow meter 4 outputs, convert 0.88～4.4V voltage signal to through R2 resistance.Level and smooth by R9, C2, export through the IC2 follower.
Two road signals by IC3, IC2 output compare through the IC5 comparator, when IC2 output signal during greater than the IC3 output signal, expression first flow meter 4 leaks with 5 pipelines that are connected of second flowmeter, then comparator IC5 exports and becomes high level, the R-S trigger saltus step that makes the IC6 formation is to low level, make relay J 1 action through R15, Q1, thereby make the 3. pin of electric butterfly valve 3 get electric and close.
Because the design has adopted the peak holding circuit that is made of LF398p, when sampling capacitance C3 got 0.01 μ F, the rate of descent of its output voltage only was 3mV/s, though I
1, I
2Signal has time-delay, but because the R2 value less than the value of R1, does not have breakage as the water pipe between the first flow meter 4 and second flowmeter 5, the voltage at resistance R 1 two ends will so just effectively have been avoided the generation of misoperation all the time greater than the voltage at resistance R 2 two ends.Long as monitored pipeline, I then
1With I
2The signal lag time will further strengthen, and can take to strengthen the way of C3, guarantee the circuit reliably working.
After electric butterfly valve 3 cut out fully, the 6. pin output low level of electric butterfly valve 3 resetted IC6, the J1 dead electricity, and electric butterfly valve 3 stops action.Before the water supply line of breakage keeped in repair,, need to disconnect K2 for guaranteeing to be perfectly safe.After repairing, press K1, make the 2. pin of electric butterfly valve 3 get electric and open.Behind complete opening, the 5. pin output low level of electric butterfly valve 3 makes the J2 dead electricity, and electric butterfly valve 3 stops action.After treating the waterflow stabilization in the water pipe, the K2 that closes makes supervisory circuit enter working state.
The solution that the utility model is convenient and practical water pipe the break water resource waste brought and the inconvenience of life, have easy for installation, reliable operation, control sensitivity, characteristics such as with low cost, can be widely used in controlling the total pipeline of water supply or the water valve of branch pipe(tube).
