[0023] The above and other technical features and advantages of the present invention are described in more detail below with reference to the accompanying drawings.

[0024] This embodiment provides a technical solution: a valve core with a detection function, such as Figures 1-4 As shown, it includes a rotating component 1 and a butterfly plate 2.

[0025] In the specific implementation, such as Figure 1 As shown, the rotating assembly 1 includes a rotating rod 101 and a handwheel 102 installed on the top of the rotating rod 101. A mounting block 13 is installed on the rotating rod 101, and the rotating rod 101 can be conveniently fixed to the valve body through the mounting block 13.

[0026] A mounting groove is provided at the vertical center position of the butterfly plate 2, and the rotating rod 101 is installed in the mounting groove. A detector 3 for detecting the liquid level is installed at the center position of one side of the butterfly plate 2 and is also arranged vertically. A drainage groove 4 is provided in the detector 3, and a detection slope 5 is provided on one side of the inner wall of the drainage groove 4. The slope can ensure that the contact area can be increased when the liquid passes through. The detection slope 5 is provided with multiple detection grooves 6 from top to bottom. When the liquid passes through the drainage groove 4, it can enter the detection groove 6. A detection component 7 is provided in the detection groove 6, and the detection component 7 can detect whether there is liquid entering the detection groove 6.

[0027] In the specific implementation, such as Figure 2 and Figure 4As shown, the detection assembly 7 includes a lightweight rod 701, an upper floating piece 702, a lower floating piece 703 and a contact switch 704. A trigger slot 8 is provided on the detection slope 5. The trigger slot 8 is located at the top of the detection slot 6 and a connecting hole is provided between the trigger slot 8 and the detection slot 6. The upper floating piece 702 and the lower floating piece 703 are respectively arranged in the trigger slot 8 and the detection slot 6. The lightweight rod 701 is welded between the upper floating piece 702 and the lower floating piece 703 and is clamped in the connecting hole. The lightweight rod 701, the lower floating piece 703 and the upper floating piece 702 can float upward under the action of hydraulic pressure. The touch switch 704 is arranged in the trigger groove 8. The contact switch 704 includes an upper contact piece 7041 and a lower contact piece 7042. The upper contact piece 7041 and the lower contact piece 7042 are used as electrodes. When they come into contact, the circuit can be connected. The lower contact piece 7042 is installed on the top of the upper floating piece 702. The upper contact piece 7041 is installed on the inner wall of the trigger groove 8 and corresponds to the lower contact piece 7042. A sealing cover piece 12 is fixedly installed on the front side of the trigger groove 8. The sealing cover piece 12 can achieve a sealing effect to prevent liquid from entering the trigger groove 8.

[0028] In the specific implementation, such as Figure 1 As shown, an observation block 9 is installed on the rotating rod 101, and an indicator light 10 and a battery 11 are provided on the observation block 9. The upper contact piece 7041 is connected to the indicator light 10 and the battery 11 respectively through wires, and the battery 11 is connected to the lower contact piece 7042 through wires. The number of indicator lights 10 is the same as that of the detection components 7 and corresponds one by one from top to bottom. Each detection component 7 can trigger the corresponding indicator light 10 after detecting liquid. Therefore, observing the number of indicator lights 10 can quickly determine the liquid level.

[0029] During detection, the butterfly plate 2 is in a flipped state and the valve body is opened and closed. When the liquid flows, it can pass through the detector 3 and enter the detection groove 6 along the detection slope 5. The lightweight rod 701, the lower floating piece 703 and the upper floating piece 702 can float upward under the action of hydraulic pressure, and then the lower contact piece 7042 can contact the upper contact piece 7041. At this time, there is a passage circuit between the upper contact piece 7041, the lower contact piece 7042, the indicator light 10 and the battery 11, so the indicator light 10 can be triggered, and the liquid level in the pipeline can be judged according to the top-down lighting of the indicator light 10.

Those skilled in the art will appreciate that many changes, modifications, and even equivalents may be made to the embodiments within the spirit and scope of the claims, all of which fall within the scope of protection of the present invention.
