Forged Steel A105 High Pressure 1.6/2.5/4.0/6.4 Mpa Rising Stem Flanged Gate Valve

Usage

Forged steel gate valve refers to the gate valve whose pressure bearing valve body and bonnet are forged. The movement direction of the opening and closing parts of the forged steel gate valve is perpendicular to the fluid direction. The forged steel gate valve can only be fully opened and closed, and cannot be adjusted or throttled; This series of valves are mainly used in petroleum, chemical industry, power station and other industries to cut off or connect the pipeline and maintain the normal operation of the system.

working principle

Valve closing: turn the hand wheel or other driving device clockwise, and the valve rod nut drives the valve rod downward to close the valve.

Valve opening: rotate the hand wheel or other driving device counterclockwise, and the valve rod nut drives the valve rod upward to open the valve.

Structural features

1. the valve stem seal is realized through the double seal design of packing + upper seal.
2 the valve rod and the ram are connected in a "t" structure, which is easy to install. In addition, the head of the valve rod is designed to be spherical, so that when the valve is closed, the valve rod and the ram are in point contact, with a self centering function.
3 the valve body adopts the slot structure to realize the ram stroke guidance, and the friction between the ram and the valve seat sealing ring is reduced during the opening and closing process.
4 the valve body and bonnet shall be connected by tenon and groove surface, which can reduce the extension and overpressure deformation of metal spiral wound gasket under the preload.
5 the valve seat adopts expansion structure to ensure compact and effective fit.
6 the movable joint is connected by bolts, nuts and pins. It has the advantages of convenient installation, simple structure, strong stability and long service life.
