Product Description

C95800 nickel aluminum bronze ball valve is mainly used to overcome the harsh conditions of strong corrosive environment, such as seawater desalination platform, various types of seagoing vessels, warships, submarines, offshore drilling platforms and other Marine equipment; And supporting facilities of polycarbonate, polyethylene, low density polyethylene, aromatics, liquefied natural gas (LNG) refinery. It is now widely used in fire fighting systems, ballast control systems, cooling systems, seawater injection systems and many other critical systems.
Second, detailed introduction of products
The nickel aluminum bronze ball valve produced by the company is safe, reliable and inexpensive, and the dynamic load on the valve stem and valve ball is also very small, so that. The friction damage is not too great, which is of great benefit to the seal. From the point of view of the float ball and the fixed ball, the fixed ball is preferred, that is, the ball is supported by the trunnion. In general, when the pressure is lower than PN40, the use of the float ball is economically and technically appropriate, because in this case, the float ball is pushed to the outlet end. In addition, a small pressure drop can be used to ensure a better seal, when the caliber is higher than DN150, often used is a fixed ball valve, this is because the ball mass of this caliber valve is very large, about 50 kg or more, in case of using a float ball, the float ball will press on the seal seat, in the operation process will cause considerable friction damage to the seal seat, otherwise, If the fixed ball is sealed along the axial flow channel, the sealing seat is not easy to seriously friction too much, relative to the pressure more than PN50 and diameter equal to DN50 ball valve, roughly use fixed ball.
Third, aluminum bronze introduction
Many bronze valves used in Marine industry are made of non-ferrous metal materials, mainly bronze and brass. Bronze, or bronze, is an alloy of red copper with tin or lead. It is called bronze because of its bluish gray color. In the classification of copper alloys, anything other than brass and white copper (copper-nickel alloys) is called bronze. Bronze has a higher strength and a lower melting point than copper (25% of tin is melted into bronze, and the melting point is reduced to 800 ° C). Pure copper (red copper) has a melting point of 1083 ° C). Bronze is castable, wear-resistant and chemically stable.
