How Does The Forged Steel Stop Valve Control The Flow Of Fluid By Moving The Valve Disc

Forged Steel Globe Valve the movement of the valve disc controls the flow of the fluid. Specifically, the valve disc of the forged steel stop valve is usually a disc or a sphere, which is located above the fluid channel inside the valve body. The movement of the valve disc is achieved through the valve stem.

When the valve is closed, the valve disc moves downward through the valve stem and fully contacts the valve seat, preventing the fluid from passing through the valve channel, thereby achieving fluid flow interruption. When the valve is opened, the valve disc moves upward through the valve stem and separates from the valve seat, allowing the fluid to pass through the valve channel, thereby achieving fluid flow.

The movement of the valve disc is usually controlled manually or by electric, pneumatic and other actuators. By adjusting the position of the valve stem, the valve disc can be accurately controlled, thereby controlling the flow of the fluid and meeting the needs of the system.

The working principle of the forged steel stop valve is basically similar to that of a conventional valve. It controls the flow of the fluid by moving the valve disc. The following is a detailed description of its working principle:

1. Valve body and valve disc structure: The forged steel stop valve consists of two parts: the valve body and the valve disc. The valve body is a hollow metal shell with a fluid channel inside. The valve disc is a disc-shaped or spherical component that is located above the fluid channel inside the valve body and can move up and down through the valve stem.

2. Fluid on-off control: When the valve is closed, the valve disc moves downward through the valve stem and fully contacts the valve seat, preventing the fluid from passing through the valve channel, thereby achieving fluid cut-off. When the valve is open, the valve disc moves upward through the valve stem and separates from the valve seat, allowing the fluid to pass through the valve channel, thereby achieving fluid flow.

3. Valve stem and operation mode: The movement of the valve disc is usually controlled by manual operation or by electric, pneumatic or other actuators. When operated manually, the valve disc is moved up and down by rotating the valve stem; while the electric or pneumatic actuator drives the valve stem through electricity or air pressure to control the movement of the valve disc.

4. Sealing performance: The valve disc must maintain good sealing performance when in contact with the valve seat to prevent fluid leakage. Normally, the contact surface of the valve disc and the valve seat adopts a metal-to-metal or metal-to-soft sealing material sealing method to ensure that the valve can be completely sealed when closed.

5. Control accuracy: By adjusting the position of the valve stem, the valve disc can be accurately controlled, thereby accurately controlling the on-off of the fluid to meet the needs of the system.

In summary, the forged steel stop valve controls the on-off of the fluid through the movement of the valve disc. Its working principle is simple and reliable, and it is suitable for fluid control applications in various industrial fields.
