Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a ball valve with high-efficiency protective functions. Background Art

[0002] A ball valve is a valve whose opening and closing parts are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for fluid regulation and control. The ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium in the pipeline, but also close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. Ball valves are divided into pneumatic ball valves, electric ball valves, and manual ball valves according to the driving method.

[0003] For example, publication number CN219242693U discloses a ball valve with an efficient protective function, including a valve body, a handle fixedly connected to the outer end of the valve stem of the valve body, a cover fixedly mounted on the outer wall of the valve body corresponding to the valve stem, a lubricating mechanism fixed to the top of the handle, and the lubricating mechanism including a liquid tank, a conduit fixedly connected to the side wall of the liquid tank, the outer end of the conduit passing through the cover and fixedly connected to an output pipe arranged opposite the valve stem. In the process of rotating the valve stem, the ring body on the outer wall of the valve stem can squeeze the movable tube, thereby pushing the movable plate to open, so that the lubricating liquid flows along the cannula to the connection between the valve stem and the valve body, thereby enabling lubrication during relative rotation, avoiding rotation obstruction and rust, achieving a good protective effect, thereby extending the service life and making operation more labor-saving;

[0004] The ball valve with high-efficiency protection function in this patent is flange-connected. Therefore, during use, the pipeline needs to be connected to the valve body through the flange. The connection is directly exposed to the outside, which is not only susceptible to environmental influences, but also prone to leakage when loose. Minor leaks are difficult for personnel to detect, posing certain safety hazards. Utility Model Content

[0005] In response to the deficiencies in the prior art, the utility model provides a ball valve with efficient protective functions, which solves the problem that pipelines need to be connected through flanges and valve bodies, and the connection is directly exposed to the outside, which is not only susceptible to environmental influences, but also prone to leakage when loose. Minor leaks are difficult for personnel to detect, posing certain safety hazards.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a ball valve with high-efficiency protection function, including a valve body, a turning handle is provided at the upper end of the valve body, connecting flanges are fixedly installed on both ends of the left and right ends of the valve body, a protective panel is provided on the outer side of the surface of the connecting flange, the end of the protective panel away from the connecting flange is fixedly connected to the protective plate, a sealing gasket is fixedly installed on the inner side of the protective plate, a sensor is provided at the bottom of the inner side of the protective panel, an alarm box is fixedly installed on the lower end of the valve body, a warning light is provided on the front end of the surface of the alarm box, and a speaker is provided on the front end of the alarm box, which is located next to the warning light.

[0007] Preferably, the protective enclosure is designed in an L-shaped structure, and the protective enclosure and the connecting flange are snap-fitted and connected, so as to provide protection and isolation for the connection.

[0008] Preferably, the protective plate is a metal spring sheet, and the protective plates are distributed in a circular ring array of the connecting flange. Due to the elasticity of the protective plate, the end of the protective plate away from the protective enclosure is in contact with the pipeline.

[0009] Preferably, the sensor is a water immersion sensor, which can sense whether there is liquid on the inner side of the protective enclosure.

[0010] Preferably, a battery pack and an information processing module are provided inside the alarm box, and the battery pack, information processing module and sensor are electrically connected. An electrical wire pipeline is provided between the alarm box and the protective enclosure. When a leakage occurs at the connection, the liquid flows into the inner side of the protective enclosure, so that the sensor senses it and the leakage can be detected in time.

[0011] Preferably, the warning light, the speaker and the battery pack are electrically connected, and the information processing module is electrically connected to the warning light and the speaker, and the warning light and the speaker are used to give prompts and alarms to prompt personnel to handle the situation in a timely manner. Beneficial effects

[0012] The utility model provides a ball valve with high-efficiency protection function. Compared with the existing technology, it has the following beneficial effects:

[0013] This ball valve with efficient protection function is equipped with a protective enclosure, a sensor and an alarm box. After the connecting flange and the pipeline are connected and fixed, the protective enclosure is moved to the outside of the connecting flange to achieve protection and isolation of the connection. The ends of the multiple protective plates away from the protective enclosure are fitted with the surface of the pipeline, so that a relatively closed space is formed between the protective enclosure and the pipeline, thereby increasing the protection effect. In addition, if the connection leaks, the liquid flows into the inside of the protective enclosure and is sensed by the sensor. At the same time, the prompt light and the speaker will give prompts and alarms, so that personnel can discover and deal with it in the first time, thereby improving safety.
