The Innovative Valve Disc Structure Improves The Precision of Fluid Control in Check Valves.

TECHNICAL EXPLANATION

1. STRUCTURAL DESIGN: It may adopt a swing-type structure, where the valve disc is connected to the valve body through a hinge mechanism and can rotate around an axis to open and close. This structure is relatively common in large-diameter valves. It enables the valve disc to have sufficient swing space when opening, and the fluid encounters relatively low resistance when passing through. It may also be a lift-type structure, where the valve disc slides along the vertical centerline of the valve body and opens and closes relying on the pressure of the medium. This type has better sealing performance.

2. MATERIAL SELECTION: Stainless steel materials such as 316L are used, which have excellent corrosion resistance and are suitable for various media, such as fluids containing corrosive substances like acids and alkalis. They can resist the erosion of the medium and extend the service life of the valve. Meanwhile, stainless steel materials also have relatively high strength and hardness and can withstand greater pressure.

3. SEALING TECHNOLOGY:Advanced sealing technologies are usually adopted, such as metal seals or soft seals. Metal seals have high sealing performance and high-temperature resistance and can maintain good sealing effects under high-pressure and high-temperature environments. Soft seals have better flexibility and sealing performance, can adapt to different working conditions, and reduce medium leakage.

4. DRIVING METHOD: Generally, it is an automatic valve, and the opening and closing of the valve disc are driven by the flow pressure of the medium itself without the need for an external power source. This driving method is simple and reliable and can automatically realize the one-way flow control of the medium under different working conditions.

ADVANTAGES DEMONSTRATED

1. LOW FLUID RESISTANCE: In the case of a swing-type check valve, when it is fully open, the fluid is hardly obstructed, and the pressure drop is relatively small, which is beneficial for the transportation of large-flow media and can reduce the energy consumption of the pipeline system. Even for the lift-type structure, through optimized design, the fluid resistance can also be controlled within a reasonable range.

2. GOOD SEALING PERFORMANCE: Whether it is a metal seal or a soft seal, it can ensure that the valve has good sealing performance when closed, effectively preventing the backflow of the medium. The advanced sealing structure and material selection make it less likely for the valve to leak during long-term use, improving the safety and reliability of the pipeline system.

3. Strong Corrosion Resistance: Stainless steel materials have excellent corrosion resistance and can resist the corrosion of various chemical media. They are suitable for pipeline systems with corrosive media in industries such as chemical engineering, petroleum, and pharmaceuticals. This not only extends the service life of the valve but also reduces the maintenance and replacement costs caused by valve corrosion.

4. STRONG ANTI-WATER HAMMER ABILITY: Through reasonable structural design and material selection, the occurrence of water hammer phenomena can be effectively reduced. For example, the closing speed of the valve disc can be controlled by adjusting the spring stiffness or damping device, enabling the valve disc to close slowly when the medium flows backward, reducing the impact of water hammer and protecting the pipeline system from the damage of water hammer.

5. WIDE APPLICATION RANGE:The large-diameter design of DN1000 is suitable for various large industrial pipeline systems, such as fluid transmission pipelines in industries like petrochemical, electric power, and metallurgy. Meanwhile, the pressure rating of 16RL can meet the requirements of most medium and low-pressure working conditions and has a relatively wide application range.

6. CONVENIENT MAINTENANCE:The structure is relatively simple with fewer parts, which is convenient for disassembly and repair. In daily use, it is only necessary to regularly check whether the sealing surfaces of the valve disc and valve seat are worn or damaged and whether components such as springs are working normally. The maintenance cost is relatively low.
