All parts of the imported high-pressure welded ball valve are forgings, using a bottom-mounted valve stem, an inverted sealing structure, an inlaid valve seat, and a ring behind the valve seat to ensure that the medium does not leak and is sealed The surface is made of nylon, and its friction coefficient is usually 1/2 that of Babbitt alloy, so it is a naturally slippery material. The high-pressure ball valve has a rotational action. The cock body is a sphere with a circular through hole or channel passing through its axis. Ball valves are mainly used in pipelines to cut off distribution and change the flow direction of the medium. They only require a rotational operation and a small rotational torque to close tightly. The main features of high-pressure ball valves are compact structure, reliable sealing, simple structure, and easy maintenance. The sealing surface and spherical surface are always in a closed state and are not easily eroded by the medium. They are easy to operate and maintain. They are suitable for water, solvents, acids, and natural gas. , but the bending strength, impact strength and high ductility are comparable to metals. Ball valves are widely used in various fields such as petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electricity, municipal steel and other industries.
Features of imported high-pressure welded ball valves
The valve body structure is integrally welded and there will be no external leakage.
The valve seat is composed of a sealing ring and a spring and has strong adaptability to changes in pressure and temperature, and will not cause any leakage within the range of use.
Anti-leakage structure of the valve stem. There is a self-sealing gasket and a shaped sealing ring at the bottom of the valve stem. There is a shaped sealing ring on the top and two sealing gaskets to ensure no leakage.
The valve body material is the same as the pipe material, so there will be no uneven stress, nor will it be extruded and deformed due to earthquakes and vehicles passing over the ground.
The valve body is light and easy to keep warm.
The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline.
The processing accuracy of the sphere is very precise, the operation is light, and there is no harmful interference.
