Description

Adjustable high-precision flange gate valve Technical Field The utility model relates to the field of flange gate valve devices, in particular to an adjustable high-precision flange gate valve. Background In water supply and drainage, heat supply, air supply and other systems of modern industrial production and civil buildings, the flange gate valve plays a vital role as a key device for controlling the flow of pipeline media. In the industrial field, the pipeline transportation system in the industries of chemical industry, electric power, petroleum and the like needs to accurately regulate the medium flow to ensure the stability and safety of the production process, and in civil buildings, the flange gate valve is not separated from the water supply system of residential communities to the air conditioning circulation system of commercial buildings to effectively control the water flow or the air flow. Therefore, the performance of the flange gate valve directly affects the operation efficiency and reliability of various systems. Currently, conventional flange gate valves have some problems in practical applications. In terms of adjusting precision, many conventional flange gate valves use a simple switch structure or a coarse adjusting mode, and precise control of the medium flow rate is difficult to achieve. For example, in some chemical production processes with extremely high requirements on flow control, conventional flange gate valves cannot meet the requirements of production processes on flow accuracy, resulting in unstable product quality or low production efficiency. The adjusting process is often judged by experience of operators, and an accurate adjusting mechanism is lacked, so that the adjusting process cannot adapt to complex and changeable working conditions. In connection stability, the traditional flange gate valve is single in connection mode, is usually fixed by only relying on simple connecting pieces such as bolts, and is easy to loosen at the connection position when being influenced by factors such as medium pressure, temperature change and pipeline vibration for a long time. Once the connection is loose, not only can the medium leak be caused, and the resource waste and the environmental pollution are caused, but also the safety accident can be caused, and the life safety of personnel and the normal operation of production facilities are seriously threatened. Moreover, the conventional flange gate valve is cumbersome to operate during maintenance and replacement of components, and consumes a lot of time and labor costs. In order to solve the technical problem, the application provides an adjustable high-precision flange gate valve.
