1.Structure and Working Principle

I.Structure

The plug valve occupies an important position by virtue of its unique structure and working principle. The core part of the cock, mostly cylindrical or cone, is provided with a through hole, like the "heart switch" of the valve. Under ordinary working conditions, the cock made of copper and cast iron can be competent; However, in the face of harsh environments such as high temperature, high pressure and strong corrosion, stainless steel, alloy steel or materials with special coatings are the "best partners", which ensure stable rotation of the cock and control the opening and closing of the fluid channel and the flow rate.
The valve body is like the "protective shell" of the cock and the "connection hub" of the pipeline, which is tubular, and the two ends of the interface are connected to the pipeline, and the connection methods such as thread, flange and welding are flexible to adapt to different specifications of the pipeline. Material selection also varies according to the scene, the general industry commonly used cast steel valve body; Industries with high demand for corrosion protection, such as chemical industry, rely on fluorine-lined, rubber-lined or corrosion-resistant alloy valve bodies.

II.Working Principle

The working principle of the plug valve is based on the rotating motion of the cock. When the plug valve is closed, the through hole of the plug and the fluid channel of the valve body are perpendicular to each other, and the fluid cannot pass through the valve and the fluid is cut off. When it is necessary to open the valve, the cock is rotated around its axis by a driving device, such as manually turning the handle, pneumatic or electric drive. With the rotation of the cock, the internal through hole is gradually aligned with the fluid channel of the valve body, and the fluid can flow from one end of the valve body through the through hole of the cock, and then flow out from the other end of the valve body, thus achieving the fluid conduction. By controlling the rotation Angle of the cock, the flow rate of the fluid can be precisely adjusted.

Multichannel Function

The plug valve can not only be used to cut off and switch on the medium flow, but also to achieve multi-channel fluid distribution and flow direction change by changing the shape of the plug body and channel layout. Three-way plug valves are widely used in chemical plants for fluid reversal and distribution, simplifying the complexity of piping systems.

Flow Regulating Function

Some plug valves have a certain flow regulation function, by precisely controlling the rotation Angle of the plug, you can flexibly adjust the flow of the medium. In some processes requiring high flow control accuracy, such as feed control of reactor in chemical production, this adjustment performance can meet the needs of fine adjustment of flow in the production process to ensure the stability of the production process and the consistency of product quality.

Exquisite Structural Design

The overall structure of the plug valve is very simple, and the core components are mainly composed of the plug, the valve body and the seal. This simple structure not only makes its internal flow path smooth, the medium flow is almost no additional obstruction, effectively reducing pressure loss.

Pressure Balance Type

Plug Valve

The pressure balance type plug valve is equipped with a special pressure balance chamber or a balance piston and other unique structures. When there is a difference in pressure on both sides of the valve, the pressure medium enters the balance chamber, pushes the balance piston action, changes the fluid flow path, and makes the pressure on both sides tend to balance. This clever design not only realizes the function of pressure balance, but also does not affect the original fluid control performance of the valve. Whether it is high pressure, medium pressure or low pressure systems, from high pressure pipelines for deep-sea oil and gas exploitation, to medium and low pressure pipe networks for urban gas transmission, to various fluid delivery systems inside factories, it can be accurately adapted to meet the needs of fluid control under different pressure levels and working conditions. In the high pressure environment, the ordinary valve sealing surface is easy to be deformed and leaked by unilateral pressure extrusion, and the pressure balanced type plug valve makes the sealing surface always closely fit through the balance pressure, ensuring excellent sealing performance, effectively preventing fluid leakage, and ensuring production safety and environmental protection requirements.
