DN700 PN10 Hydraulic Tilting Disc Slanted Seat Check Valve

Jun 20,2022

DN700 PN10 Hydraulic Tilting Disc Slanted Seat Check Valve

Tilting disc check valves are generally used in agricultural applications but they may be used in other applications as well.  The valves are used when there is frequent flow reversal. The disc acts almost as n air foil so once it is fully open, the process easily holds it open.  This is different than a swing check valve where the velocity of the process must be high enough to keep the check valve open. The tilting disc is much lighter and smaller than the disc in a swing check valve.  Additionally, the center of gravity for the disc is very close to its pivot point.  This means that the cracking pressure is much lower.  The tilting disc check valve has much lower pressure drop at low flows than the swing check valve.  However, at higher flow rates, the tilting disc has a higher pressure drop than the swing check valve.

Ductile Iron Foot Valve manufacturers take you to understand the precautions

Ductile Iron Foot Valve manufacturers tell you that ductile iron has rapidly developed into a widely used cast iron material, second only to gray iron. The so-called "replacing steel with iron" mainly refers to ductile iron. 1. The manufacturer of Ductile Iron Foot Valve tells you that the chemical composition is strictly required, and the carbon and silicon content of the original iron liquid is higher than that of gray cast iron, which reduces the content of manganese, phosphorus and sulfur in ductile iron. 2. The melting temperature of molten iron is higher than that of gray cast iron to compensate for spheroidization and the loss of molten iron temperature during inoculation treatment. 3. Carry out spheroidizing treatment, that is, add a spheroidizing agent to the molten iron. 4. Add an inoculant for inoculation treatment. 5. Ductile Iron Foot Valve manufacturers tell you that ductile iron has poor fluidity and large shrinkage, so it needs a higher pouring temperature and a larger pouring system size, rationally apply risers, cold iron, and adopt the principle of sequential solidification. 6. Perform heat treatment. ① Annealing. The ferrite matrix is ​​obtained, the plasticity and toughness are improved, the stress is relieved, and the cutting performance is improved. ② normalizing. A pearlite matrix is ​​obtained, which improves strength and wear resistance. ③Conditioning and tempering. Obtain the matrix structure of tempered sorbite and good comprehensive mechanical properties, such as main shaft, crankshaft, connecting rod, etc. ④ isothermal quenching. Ductile Iron Foot Valve manufacturers tell you that the parts with complex shapes and high comprehensive performance requirements can obtain the matrix structure of lower bainite, as well as comprehensive mechanical properties such as high strength, high hardness and high toughness, so as to avoid cracking during heat treatment, such as main shaft and crankshaft. , gears, etc.

Parts with high performance requirements. Ductile Iron Bottom Valve manufacturers tell you that ductile iron has rapidly developed into a widely used cast iron material, second only to gray iron. The so-called "replacing steel with iron" mainly refers to ductile iron. Ductile Iron Bottom Valve manufacturers tell you that the development speed of ductile iron as a new engineering material is amazing. The development speed of ductile iron production is particularly fast in industrialized countries. With its excellent performance, it can sometimes replace expensive cast steel and forged steel in use, and is widely used in the machinery manufacturing industry.
