The ordinary electric control structure is not easy to intelligently control the opening size of the valve body, which leads to poor functionality of the device. Secondly, it can often only be powered by an external power supply, the power supply method is relatively single, and the flexibility is not high. To address these defects, we propose a new contact-sealed butterfly valve based on a hydraulic mechanism. Summary of the invention

[0009] Preferably, both ends of the top of the upper valve shell are welded with limit slide bars, and both ends of the operating hand plate are provided with limit openings slidably connected to the limit slide bars, so that the sliding limit effect formed by the limit slide bar and the limit opening is utilized to improve the stability of the micro electric hydraulic cylinder driving the valve core driving rod when it moves up and down.

[0010] Preferably, the top of the piston rod is connected to one side of the operating handle by welding.

[0013] Preferably, fixing cavities matching the circuit board and the rechargeable lithium battery are respectively provided on both sides of the battery box.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) The contact-sealed butterfly valve based on the hydraulic mechanism optimizes its own performance by installing a piston rod, etc. On the one hand, the user can start the micro-electric hydraulic cylinder to drive the piston rod to move, thereby driving the valve core drive rod fixed to the top of the piston rod to automatically rise and fall, which can realize the automatic drive control of the device based on the hydraulic mechanism, which is highly convenient and labor-saving. Compared with the common manual operation, it can better prevent the valve core drive rod and the operating hand plate from loosening. On the other hand, by installing a laser ranging sensor on the top of the micro-electric hydraulic cylinder and providing a positioning piece matching the laser ranging sensor on the piston rod, the extended length of the piston rod can be monitored in real time, and the data can be sent to the single-chip microcomputer for calculation and processing, and then converted to obtain the depth of the valve core drive rod extending into the lower valve shell, so as to facilitate the intelligent control of the valve core blocking structure at the bottom of the valve core drive rod for the butterfly valve.

The rechargeable lithium battery can also be used for emergency power supply in the event of an unexpected power outage when the external power supply is connected. On the other hand, the battery power measurement chip on the circuit board is used to monitor the current through a small detection resistor located between the rechargeable lithium battery and its load, so as to realize intelligent measurement of the power of the rechargeable lithium battery, send the monitored data to the single-chip microcomputer, and then directly display the power through the display screen on the operation panel. This ensures the safety of the device when it is powered by no additional external power supply, which makes the power supply mode of the device diverse, safe and flexible. (3) The contact-sealed butterfly valve based on the hydraulic mechanism optimizes its own structure by installing a limit slide bar and the like.

On the other hand, by fixing a threaded assembly clamp at the bottom of the battery box and welding a threaded assembly seat threadedly connected to the threaded assembly clamp on the outer wall of the lower valve shell, the device can realize independent disassembly and maintenance of the battery box, which enables the main structure and the control power supply structure of the device to be assembled separately for easy maintenance.
