Abstract
The utility model discloses an automatic control valve, belonging to the field of heating devices. The utility model aims at providing an automatic control valve in which a water inlet and a water outlet can be automatically closed when a water leakage point exists in a heating system. The automatic control valve is provided with a return water port valve and a water supply port valve on a water return port and a water supply port respectively; the water return port valve and the water supply port valve are respectively controlled by a water return valve controller and a water supply valve controller; the water return port and the water supply port are respectively provided with a water return port flow sensor and a water supply port flow sensor; the water return valve controller, the water supply valve controller, the water return port flow sensor and the water supply port flow sensor are all connected with a controller. The automatic control valve has the advantages of simplicity in structure and convenience for installation and use. The automatic control valve disclosed by the utility model can be automatically closed for preventing the waterway systems of the heating devices and the like from water leakage, and has the advantages of reasonable design, convenience for use and capability of being closed through intelligent control when the pipeline is in water leakage, and thus, losses caused by the water leakage of the pipeline are effectively avoided.
Description
Technical field
The utility model belongs to the heating devices field.
Background technology
The heating of north of china in winter is absolutely necessary, and multiple heating systems such as radiator heating, geothermal heating are arranged, and the whole circulatory system has many pipelines and joint etc.; Sometimes produce leakage point; Need artificial valve-off this moment, and when dew point is very little, be not easy to find very much; Can not on-call maintenance or control, cause unnecessary waste and trouble easily.
Summary of the invention
The purpose of the utility model provides a kind of when leakage point appears in heating system, can close the autocontrol valve of intake-outlet automatically.
The utility model is separately installed with water return outlet valve and feed water inlet valve on water return outlet and feed water inlet; Water return outlet valve and feed water inlet valve are respectively through backwater valve controller and the control of water supply valve controller; On water return outlet and feed water inlet, be separately installed with water return outlet flow sensor and feed water inlet flow sensor, backwater valve controller, water supply valve controller, water return outlet flow sensor and feed water inlet flow sensor all link to each other with controller.
The utility model is simple in structure, and is easy to install.The utility model is a kind of water circuit systems such as heating to be prevented the control valve that can close automatically that leaks, and is reasonable in design, easy to use, when pipeline takes place to run when leaking, and can be through Based Intelligent Control and valve-off avoids pipeline to run the loss of leaking and bringing effectively.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model is separately installed with water return outlet valve 7 and feed water inlet valve 6 on water return outlet 9 and feed water inlet 5; Water return outlet valve 7 is controlled through backwater valve controller 2 and water supply valve controller 3 respectively with feed water inlet valve 6; On water return outlet 9 and feed water inlet 5, be separately installed with water return outlet flow sensor 8 and feed water inlet flow sensor 4, backwater valve controller 2, water supply valve controller 3, water return outlet flow sensor 8 and feed water inlet flow sensor 4 all link to each other with controller 1.
The operation principle of the utility model is:
The water flow data of water return outlet flow sensor 8 and feed water inlet flow sensor 4 collection water return outlets 9 and feed water inlet 5 processes; These data are sent to controller 1; Two data of 1 pair of collection of controller compare, if two data produce the difference of setting, then have been judged as leakage point; Send out code to backwater valve controller 2 and water supply valve controller 3 simultaneously then; To close water return outlet valve 7 and feed water inlet valve 6 on water return outlet 9 and the feed water inlet 5 simultaneously automatically at backwater valve controller 2 and water supply valve controller 3, thereby whole pipe will be stopped the circulation of recirculated water, control leaking of leakage point.
1, a valve is installed in water inlet, and the flow of water inlet and water outlet equates under valve normal condition of water outlet installation, two valves occur closing simultaneously automatically when flow does not wait;
2, adopting water flow sensor is detecting element, and parameter request stability obvious parameter drift can not occur at 0～90 degree centigrade;
3, start detects.System begins to calculate once in per 10 minutes or 30 minutes at the water outlet calculated flow rate respectively of intaking after switching on, and prompting is normal then control valve is failure to actuate, is given a green light if detection is intake, the circling water flow rate value is equal;
If 4 survey water inlet, circling water flow rate error (can specification error permissible value) is arranged, detect water steathily or in setting value 1 minute of leaking, the prompting of closing simultaneously and send out a warning simultaneously of two valves of Inlet and outlet water;
5, the utility model mainly is applied to heating system, ground heating system etc., also can be applied in the circulatory system of the automatic control that other water pipes prevent to leak.
