Globe valve, also known as shut-off valve, is one of the most widely used valves. Its popularity is due to the small friction between sealing surfaces in the process of opening and closing, relatively durable, small opening height, easy manufacturing and convenient maintenance. It is not only suitable for medium and low pressure, but also suitable for high pressure. The closing principle of the globe valve is to make the sealing surface of the valve disc and the sealing surface of the valve seat close together by relying on the pressure of the valve rod to prevent the medium from flowing. The structural length of the globe valve is larger than that of the gate valve, and the fluid resistance is large, so the sealing reliability is not strong in long-term operation.

As one of the most important cut-off valves, globe valve plays an important role in aerospace field. As an important component of aerospace equipment, the globe valve realizes the functions of medium transportation, stop and adjustment, and its sealing performance directly affects the safe and reliable operation of aerospace equipment. The research on the influencing factors and rules of the sealing characteristics of typical globe valves has guiding significance for the structural design of the valve sealing pair, so as to improve the sealing performance and reliability of the valve.

Working principle and characteristics of globe valve

The valve plays an important role in cutting off and throttling the medium in the pipeline where it is located. As an extremely important cut-off valve, the sealing of the globe valve is to apply torque to the valve stem, and the valve stem applies pressure to the valve disc in the axial direction, so as to make the sealing surface of the valve disc fit closely with the sealing surface of the valve seat, and prevent the medium from leaking along the gap between the sealing surfaces.

The sealing pair of globe valve is composed of disc sealing surface and seat sealing surface. The stem drives the disc to move vertically along the center line of the seat. In the process of opening and closing the globe valve, the opening height is small, the flow rate is easy to adjust, the manufacture and maintenance are convenient, and the pressure application range is wide.

Compared with another commonly used globe valve in industrial production, the globe valve is simpler in structure and easier to manufacture and maintain. In terms of service life, the sealing surface of the globe valve is not easy to be worn and scratched, and the valve disc is not easy to be damaged in the process of valve opening and closing.There is no relative sliding between the sealing surfaces of the block, so the wear and scratch of the sealing surface are small, so the service life of the sealing pair is improved. In the process of full closing, the valve disc stroke is small, and its height is relatively small. The disadvantage of the globe valve is that the opening and closing torque is large, and it is difficult to achieve rapid opening and closing. Because the flow channel in the valve body is more tortuous, the fluid flow resistance is large, resulting in greater loss of fluid power in the pipeline.
