DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following are specific embodiments of the present utility model in combination with the accompanying drawings, and the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0019] Such as Figures 1 to 2As shown in the figure, the intelligent leak-proof and water-supplying valve includes an intelligent controller 100 and a valve body 200. Water inlet connectors 210 and water outlet connectors 220 are respectively installed at both ends of the valve body 200. The water inlet connector 210 is connected to a water inlet pipe, and the water outlet connector 220 is connected to a water circulation closed system. A controller connector 240 is formed at the top of the valve body 200, and the controller connector 240 is connected to the intelligent controller 100. A sensor connector 230 is formed at the bottom of the valve body 200 between the controller connector 240 and the water outlet connector 220. A pressure sensor 120 is fitted inside the sensor connector 230, and the pressure sensor 120 sends the pressure condition inside the valve cavity 201 of the valve body 200 to the intelligent controller 100 through a signal transmission line 130.

[0020] A connecting sleeve 110 extends downward from the bottom of the intelligent controller 100. The connecting sleeve 110 and the controller connector 240 are fixedly connected by threaded connection. A gasket 112 is sleeved at the connection between the connecting sleeve 110 and the controller connector 240. A circular protrusion is formed circumferentially on the connecting sleeve 110, and anti-slip teeth 111 are formed on the outer side wall of the circular protrusion. The anti-slip teeth 111 facilitate the user to install and connect the intelligent controller 100 and the controller connector 240 by screwing without slipping.

[0021] Further explanation: An alarm indicator light 101 is provided on the intelligent controller 100. After the pressure sensor 120 detects a pressure change, if the algorithm program of the intelligent controller 100 determines that the pressure change does not conform to the change law and amplitude under normal circumstances, it is determined that a leakage has occurred inside the water circulation closed system, and the alarm indicator light 101 lights up to prompt the user.

[0022] As Figure 2 shown in the figure, the water inlet connector 210 is connected to the valve body 200 through a water inlet locking sleeve 212. External threads are formed on the outer side walls at the connection between the water inlet connector 210 and the valve body 200, and internal threads are formed on the inner side wall of the water inlet locking sleeve 212. The water inlet locking sleeve 212 is connected by threading to wrap the connection between the water inlet connector 210 and the valve body 200 to fix the two. Similarly, the water outlet connector 220 is connected to the valve body 200 through a water outlet locking sleeve 222. Corresponding threads are provided on the outer side wall at the connection between the water outlet connector 220 and the valve body 200 and on the inner side wall of the water outlet locking sleeve 222. The water outlet locking sleeve 222 is connected by threading to wrap the connection between the water outlet connector 220 and the valve body 200 to fix the two.

[0023] A water inlet 211 is provided at the center of the water inlet joint 210, and a water outlet 221 is provided at the center of the water outlet joint 220. Both the water inlet 211 and the water outlet 221 are connected to the valve cavity 201 inside the valve body 200. A valve stem 241 is installed in the controller joint 240. A spherical valve core 242 is connected to the bottom of the valve stem 241, and a water flow channel is provided in the center of the spherical valve core 242. If the opening of the water flow channel is staggered with the valve cavity 201, the ball valve is in a closed state, and the water inlet 211 is not connected with the water outlet 221; if the opening of the water flow channel overlaps with the valve cavity 201, the ball valve is in an open state, the water inlet 211 is connected with the water outlet 221, and the water inlet pipeline replenishes water inside the water circulation closed system; according to the different angles at which the valve stem 241 controls the rotation of the spherical valve core 242, the larger the overlapping part of the water flow channel opening with the valve cavity 201, the greater the amount of water replenishment per unit time.

[0024] The inner wall of the sensor connector 230 is provided with a connector internal thread 231, and the pressure sensor 120 is fixedly connected to the sensor connector 230 through a threaded connection. The pressure sensor 120 is located in the valve cavity 201 between the water outlet 221 and the spherical valve core 242, and the air pressure change in the water circulation closed system is determined by real-time detection of the air pressure value in the valve cavity 201. A sealing ring 232 is installed at the end of the connector internal thread 231 between the sensor connector 230 and the pressure sensor 120 to prevent water leakage at the sensor connector 230, so as not to affect the accuracy of the air pressure value detection in the valve cavity 201.

[0025] The utility model has three working modes:

[0026] 1. Manual mode: By directly screwing the connecting sleeve 110 with the anti-slip teeth 111, the valve stem 241 inside the intelligent controller 100 can be driven to rotate, thereby adjusting the angle of the spherical valve core 242 to achieve the water intake amount when the valve is switched and replenished.

[0027] 2. Automatic water replenishment mode: Under the premise that there is no leakage in the closed water circulation system, if the pressure sensor 120 detects that the pressure inside the valve cavity 201 is lower than the set pressure value, the intelligent controller 100 automatically controls the opening of the ball valve to replenish water to the system; if the pressure inside the valve cavity 201 is equal to or higher than the set pressure value, the ball valve automatically closes and stops replenishing water.

[0028] 3. Water leakage detection mode: When the ball valve is closed and the water circulation closed system is in operation, if the pressure sensor 120 detects that the pressure in the valve chamber 201 is unchanged, there is no water leakage; if the pressure in the valve chamber 201 drops slightly over a period of time, there is a small leakage point in the system causing dripping, and the intelligent controller 100 issues a leakage alarm; if the pressure in the valve chamber 201 drops sharply in a short period of time, a burst leak occurs in the system, and the intelligent controller 100 immediately issues a leakage alarm.

[0029] When the ball valve is open and the water circulation closed system is in the water replenishment state, first set the water replenishment time. If the detected pressure change within this time period does not conform to the pressure change range under normal ball valve closing conditions, there is a leak in the system. While the intelligent controller 100 gives a leak alarm, it automatically closes the ball valve.

[0030] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways to substitute, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0031] Although various terms are used more frequently herein, the possibility of using other terms is not excluded. Using these terms is only for more conveniently describing and explaining the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
