Working principle
The working principle of the wafer type flange ball valve is to control the flow of fluid by rotating the ball. When the channel on the sphere aligns with the channel on the valve body, the valve is in the open state and fluid can freely pass through; When the sphere rotates 90 degrees, the channels are staggered and the valve is in a closed state, cutting off the flow of fluid.

The sealing ring made of elastic materials such as polytetrafluoroethylene is easy to seal, and the sealing ability of the ball valve increases with the increase of medium pressure, which can effectively prevent medium leakage and internal leakage

Structure and Principle

Structural composition: mainly composed of spherical body, valve seat, valve stem, valve body, seals and other components. The sphere is the core component, the valve seat is used to seal the sphere, the valve stem is connected to the sphere and used to operate the rotation of the sphere, and the valve body is the outer shell of the entire valve. The sealing element ensures the sealing performance of the valve.
Working principle: The valve is opened and closed by rotating the sphere. When the channel of the sphere coincides with the axis of the pipeline, the valve is in the open state, and the medium can pass smoothly; When the sphere rotates 90 ° and its channel is perpendicular to the pipeline axis, the valve is in a closed state, cutting off the flow of the medium.

 

characteristic

 Strong corrosion resistance: 304 stainless steel contains sufficient chromium and nickel, which can form a dense oxide film on the surface, effectively resisting the erosion of most acids, alkalis, salts, and organic solvents, and can be used for the transportation of various corrosive media.
Good sealing performance: The sealing ring made of elastic materials such as polytetrafluoroethylene is easy to seal, and the sealing ability of the ball valve increases with the increase of medium pressure, effectively preventing medium leakage and internal leakage.
Low fluid resistance: When the full diameter ball valve is opened, the ball channel, valve body channel, and connecting pipe diameter are equal and form one diameter, and the medium can flow almost without loss. Its resistance coefficient is equal to that of a pipe section of the same length.
Easy to operate: It opens and closes quickly, only needs to rotate 90 ° from fully open to fully closed. The operating torque is small, making it convenient for remote control and manual operation, and also easy to achieve automation control.
Easy maintenance: Ball valves have a simple structure, and the sealing rings are generally movable, making disassembly and replacement relatively convenient, with lower maintenance costs.
Widely applicable: with diameters ranging from a few millimeters to several meters, it can be used from high vacuum to high pressure and is suitable for various media such as water, steam, oil, nitric acid, acetic acid, urea, etc

Advantages

 Reliability:Provides a reliable and long-lasting solution for flow control.

 Ease of Maintenance:Simple design allows for easy maintenance and repair.

 Versatility:Suitable for a wide range of applications and media.

 Safety:Ensures a secure and leak-proof operation, enhancing safety in industrial environments.

application area 

Petrochemical industry: a pipeline transportation system used to transport various corrosive chemical raw materials, oil products, natural gas and other media, such as sulfuric acid, hydrochloric acid, caustic soda and other chemical products.
Food and beverage industry: Due to its non-toxic and harmless nature, 304 stainless steel meets food hygiene standards and can be used for pipeline control in the production and transportation processes of food and beverages, such as milk, juice, beer, etc.
Pharmaceutical industry: used in the pharmaceutical production process to transport various drugs, solvents and other media, ensuring the hygiene and safety of the drug production process.
Building water supply and drainage industry: used for building water supply and drainage systems, controlling the flow and distribution of water, such as water pipelines, sewage discharge pipelines, etc.
Power industry: can be applied to cooling water circulation systems, steam transmission pipelines, etc. in the power system to ensure stable operation of the system.
