Structural characteristics and advantages of forged steel internal thread gate valve:
(1). The structure design of the gate valve is reasonable, the sealing is reliable, the channel is smooth, and the flow resistance coefficient is small.
(2). The disc and sealing surface overlay by iron-based alloy or Stellite, which have many advantages, like wear-resistant, high-temperature resistant, corrosion-resistant, anti-scratch performance and long service life.
(3). The utility model adopts a wedge-shaped elastic shutter or a steel wedge-type single shutter structure, and a rolling bearing is arranged in a medium and large diameter, the switch is flexible, and the opening and closing is easy.
(4). The valve stem is tempered and surface nitrided for good corrosion resistance, scratch resistance and wear resistance.
(5). Various pipe flange standards and flange sealing surface types can be used to meet various engineering needs and user requirements.
(6). The valve body material is complete in variety, the packing and gasket can be reasonably matched according to the actual working conditions or user requirements, and can be applied to various pressure, temperature and medium working conditions.
