As one of the important valves, the globe valve plays an important role in the aerospace field. As an important equipment of aerospace equipment, the globe valve realizes the functions of conveying, intercepting, and adjusting the medium, and its sealing performance directly affects the safety of aerospace equipment. Reliable operation.
The working principle and characteristics of the globe valve: the valve cuts off the medium in the pipeline, which plays an important role in throttling. The pressure makes the sealing surface of the valve body and the sealing surface of the valve seat close to prevent the medium from leaking along the gap between the sealing surfaces. The sealing pair of the globe valve is composed of the sealing surface of the valve body and the sealing surface of the valve seat. The valve body makes the valve body move vertically along the center line of the valve seat. The shut-off valve has a small opening and closing height, easy flow adjustment, easy manufacturing and maintenance, and a wide range of pressure applications.
In terms of service life, the sealing surface of the globe valve is not easy to wear and damage, and there is no relative sliding between the valve body and the sealing surface during valve opening and closing, so the wear and damage of the sealing surface are small, which improves the service life of the sealing pair. The stroke of the middle valve body is small.
