Description

A device for monitoring the opening and closing of a vent pipe valve

Technical Field

The utility model relates to the technical field of vent pipe valve monitoring, in particular to a vent pipe valve opening and closing monitoring device.

Background Art

A vent pipe is a pipe or pipe fitting used for ventilation or exhaust, commonly found in various mechanical equipment or industrial facilities. Its design usually takes into account the smooth flow of fluid and the high efficiency of exhaust. For example, in a gas station, the vent pipe plays a key role in the refueling process. It is connected to the fuel tank to ensure the balance of air pressure inside and outside the tank and prevent oil leakage or splashing. In addition, ball valves, as a common type of valve, are also often used in conjunction with vent pipes. Ball valves control the flow of fluid by rotating the ball. Their simple structure and reliable performance make them popular in various industrial scenarios.

At present, the existing device (such as patent number: CN207470816U) discloses a "ball valve", the connecting pipe end of the ball valve can be connected to the pipeline, and when in use, the handle can be rotated by hand to drive the threaded rod to rotate in the threaded hole, and the sealing ball is screwed from the support pipe into the connecting pipe, so that the sealing ball and the sealing gasket fit tightly. Since the diameter of the sealing ball is larger than the diameter of the connecting pipe, and the sealing ball and the sealing gasket have very good sealing performance, the valve can be tightly closed to prevent liquid from flowing out of the connecting pipe, and the sealing ball can be screwed back from the connecting pipe to the supporting pipe by rotating the handle counterclockwise, and the liquid can flow out of the connecting pipe again. The ball valve can effectively prevent leakage;

However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: when the existing device is in use, since the hollow ball core and the valve stem are usually made of metal material, after long-term use, the contact surface between the two will easily form scale or grease, making the rotation angle of the ball valve easily blocked by scale or grease, and then making the rotation angle not the actual closing angle. Therefore, the staff cannot know the actual closing and opening status of the ball valve, affecting subsequent operations, and the practicality needs to be improved.
