AI Technical Summary
Existing non-stick gate valves cannot accurately record the degree of opening and closing, resulting in large errors in manual counting, and lack a real-time display device, making operation inconvenient.
Design a device comprising a connecting disc, a counter, a connecting rod, and a pinion to record revolutions through intermittent meshing of incomplete external teeth, and combine a mechanical gear counter and a 2:1 reduction gear set to ensure accurate counting.
It enables accurate recording of the number of gate valve rotations, avoids errors from manual counting, provides an intuitive display of the on/off status, and improves operational efficiency.

Abstract
Claims
1. A device for recording the number of rotations of a gate valve, characterized in that: The device includes a connecting plate, a counter, a connecting rod, and a pinion; the connecting plate is coaxially fixed to the outside of the rotating part of the gate valve, and the outer circumference of the connecting plate is provided with incomplete external teeth; the counter is located on the top of the gate valve; the pinion is coaxially fixed to one end of the connecting rod; the other end of the connecting rod meshes with the inside of the counter; the outer circumferential teeth of the pinion intermittently mesh with the incomplete external teeth of the outer circumference of the connecting plate.
2. The device for recording the number of revolutions of a gate valve according to claim 1, characterized in that: The counter is a mechanical gear counter.
3. The device for recording the number of revolutions of a gate valve according to claim 2, characterized in that: The counter includes a counter housing and digital gears that are sequentially rotated and connected inside the counter housing.
4. The device for recording the number of revolutions of a gate valve according to claim 1, characterized in that: The intermittent period of engagement between the incomplete outer teeth of the pinion and the incomplete outer teeth of the connecting disc is one rotation of the connecting disc.
5. The device for recording the number of revolutions of a gate valve according to claim 2, characterized in that: When the connecting disc rotates one revolution, the incomplete outer teeth of its outer circumference drive the pinion to rotate half a revolution.
6. The device for recording the number of revolutions of a gate valve according to claim 5, characterized in that: The connecting rod is linked to the digital gear through a 2:1 reduction gear set.
