The electric shut-off valve is mainly used to cut off the medium in the pipeline or to regulate the flow rate. It realizes the opening and closing of the valve through the electric drive device, which has the characteristics of high efficiency, safety, reliability and convenience. In industrial production, electric globe valves are widely used in pipelines of water, steam, oil, gas and other media, playing a role in controlling flow, pressure, temperature and other parameters, and is one of the indispensable and important components in industrial automation control systems.
The working principle of the electric shut-off valve is:
The valve stem is driven by an electric drive device, which causes the disc to reciprocate in the valve seat to realize the opening and closing of the valve. According to different working principles, electric globe valves can be divided into three types: straight-through, angle, and Y-type. Straight-through electric globe valve refers to the direct state between the fluid channel and the valve body, and is generally used when the medium in the pipeline is liquidAngular electric shut-off valve refers to the fluid channel and the valve body at an angle of 90 degrees, which is generally used when the medium in the pipeline is gasY-type electric shut-off valve means that the fluid passage is Y-shaped with the valve body, which is suitable for high-viscosity, suspended solids and particulate media.
The characteristics of the electric shut-off valve are:
1.High efficiency: The electric globe valve adopts an electric drive device, which can realize fast opening and closing, and improve work efficiency. At the same time, due to the large contact area of the sealing surface of the globe valve, the sealing performance is good, and the flow, pressure and temperature of the medium in the pipeline can be effectively controlled.
2.Safety: The electric globe valve has a double sealing structure, which can ensure that it can maintain good sealing performance under extreme working conditions, prevent medium leakage and leakage, and ensure the safety of industrial production.
3.Reliability: The mechanical transmission parts of the electric globe valve have been precision machined and strictly tested to ensure the stability and reliability of the valve in the process of long-term use. At the same time, the disc and seat of the globe valve are made of cemented carbide material, which has good wear resistance and long life.
4.Convenience: The electric shut-off valve is electrically driven, does not need to be operated manually, and can be controlled remotely and automatically. At the same time, the valve is compact in structure, small in size, light in weight, easy to install and maintain.
