Definition, Structure And Working Principle Of Forged Steel Valves
Forged steel valve is a commonly used fluid control device with the characteristics of high strength, high temperature resistance and corrosion resistance, and is widely used in the industrial field. It is manufactured by forging process and has the advantages of strong structure, high reliability and good sealing. The definition, structure and working principle of forged steel valves will be introduced in detail below.
Definition of forged steel valve:
Forged steel valve is a valve manufactured by forging process. Its main components are made of high-strength forged steel materials. It has the characteristics of high temperature resistance and corrosion resistance. It has good performance under high temperature, high pressure and corrosive media. Forged steel valves are usually connected by threaded connection, welding connection or flange connection to control the switch and regulation of fluid.
Structure of forged steel valve:
Forged steel valves are generally composed of the following parts:
1. Valve body: The valve body of Forged Steel Valve is usually manufactured by forging process and has the characteristics of high strength and strong pressure resistance. The valve body is provided with flow channels and orifices for fluid control and regulation.
2. Valve cover: The valve cover is an important part of the forged steel valve. It is connected to the valve body and plays a role of sealing and pressure bearing. The valve cover can be bolted, welded or threaded.
3. Valve disc: The valve disc is the control element of the forged steel valve, which is responsible for controlling the on-off and regulation of the fluid. The valve disc is usually in a disc or spherical structure and is connected to the valve seat through the valve stem.
4. Valve stem: The valve stem connects the valve disc and the manual or electric operating mechanism to open and close the valve disc. The valve stem has corrosion and wear resistance to ensure the reliability and sealing of the valve disc.
5. Sealing device: In order to ensure that the forged steel valve has good sealing performance in the closed state and prevent fluid leakage, the forged steel valve is usually equipped with sealing devices such as packing, sealing rings and metal seals.
Working principle of forged steel valve:
The working principle of forged steel valve is mainly based on the opening and closing and relative movement between the valve disc and the valve seat. The following is the working process of the forged steel valve:
1. Open state: When the operating rod or electric mechanism lifts the valve disc through the valve stem, the valve disc is separated from the valve seat and the fluid can pass smoothly. In this state, the valve is in an open state, allowing fluid to flow.
2. Closed state: When the operating lever or electric mechanism presses the valve disc down, the valve disc seals with the valve seat to prevent the fluid from passing. In this state, the valve is in a closed state to prevent the fluid from flowing.
3. Adjustment state: By adjusting the position of the valve disc, the flow and pressure of the fluid can be controlled to achieve the regulation of the fluid.
In summary, the forged steel valve is a valve manufactured by forging process, which has the characteristics of high strength, high temperature resistance and corrosion resistance. It consists of a valve body, a valve cover, a valve disc, a valve stem and a sealing device. The forged steel valve realizes the opening and closing and regulation of the fluid through the opening and closing and relative movement between the valve disc and the valve seat. It has a sturdy structure, high reliability and good sealing performance, and is widely used in fluid control and regulation in the industrial field.
