It is suitable for water, steam and oil pipeline, with high temperature and high pressure resistance.
It is suitable for cutting off or connecting the medium on the pipes of water, steam, oil and superheated steam of high temperature and high pressure in thermal power plant, petrochemical industry, metallurgy, etc.
High temperature and high pressure globe valve, also known as shut-off valve, is the most widely used valve. The reason why it is widely popular is that the friction force between the sealing surfaces is small in the opening and closing process, relatively durable, small in opening height, easy to manufacture and easy to maintain. It is not only suitable for medium and low pressure, but also suitable for high pressure. Its closing principle is that, depending on the pressure of the valve rod, the sealing surface of the valve disc and the sealing surface of the valve seat closely fit together to prevent the medium from flowing.
The insulation stop valve only allows one-way flow of medium and has directionality during installation. Its structural length is longer than that of gate valve, at the same time, the fluid resistance is large, and the sealing reliability is not strong in long-term operation.
High temperature and high pressure globe valve is a kind of high temperature and high pressure stop valve. The opening and closing parts of the high temperature and high pressure stop valve are plug-shaped disc, the sealing surface is flat or conical, and the valve disc moves in a straight line along the center line of the fluid.
