Advantages and characteristics of Shanghai manual gate valve
The opening and closing parts of the Shanghai manual gate valve are mainly controlled by the opening of the gate. The direction of movement of the gate and the direction of the fluid just deal with the vertical direction. Therefore, the Shanghai manual gate valve can only be fully opened or closed, and cannot be adjusted and throttled. Of course, this shortcoming also allows Shanghai's manual gate valve to have a small fluid resistance, making its sealing surface less eroded and eroded by the medium. It is relatively labor-saving to open or close, the flow direction of the medium is not restricted, does not disturb the flow, does not reduce the pressure, the shape is simple, the structure length is short, the manufacturing process is good, and the scope of application is wide.
2. The gate and sealing surfaces of offshore manual gate valves are made of iron-based alloys or Stellite cobalt-based hard alloys. They are wear-resistant, high-temperature resistant, corrosion-resistant, and have a long service life.
3. Shanghai manual gate valve adopts wedge-type elastic gate or steel wedge-type single gate structure. Rolling bearings are installed in medium and large calibers. The switch is flexible and easy to open and close.
4. The stem of the offshore manual gate valve is quenched and tempered and the surface is nitrided. The Shanghai manual gate valve has good corrosion resistance, abrasion resistance and abrasion resistance.
5. The offshore manual gate valve can adopt various piping flange standards and flange sealing surface types to meet the needs of various projects and user needs.
6, Shanghai manual gate valve body material is complete, packing, gasket can be reasonably selected according to the actual working conditions or user requirements, can be suitable for various pressure, temperature and medium working conditions.
