The working principle of gate valve

         Gate valve with the valve stem with a straight line, called the lift rod valve. Usually in the lift rod with trapezoidal thread, through the guide groove nut valve and the valve on the top, the rotary motion into linear motion, which is the operating torque thrust into operation. Sealing surface can only rely on media pressure to seal, that media pressure will depend on the sealing surface pressure gate to the other side of the seat to ensure the sealing surface of the seal, which is self sealing. Most of the valve is sealed by force, that the valve is closed, to rely on externalpressure to force the gate to the seat, to ensure the sealingsurface of the seal.

     Characteristic

     1.Fine material, in accordance with the relevant standards at home and abroad, the overall high quality materials.

     2.Meet the requirements of domestic and foreign advanced standards, reliable performance, beautiful appearance, goodsealing.

Basic Rubber Tensioner

     3.The sealing pair is advanced and reasonable, the sealing surface of the gate and the seat of the use of different hardness of Si Taili (Stellite) cobalt based alloy welding and become,reliable seal, high hardness, wear resistance, high temperature resistance, corrosion resistance, good anti abrasion performance, long life.

     4.Stem through the quenching and tempering and surfacenitriding treatment, with good corrosion resistance, scratch resistance and abrasion resistance.

     5.Using flexible wedge gate structure, the large-diameter setthrust bearing, the friction force is small, and is equipped withimpact manual, opening and closing the ease.
