Bola de válvula de carburo de tungsteno

Bola de válvula de carburo de tungsteno is an important part of globe valve , globe valve can make use of the handle or other drive means rotating sphere 90. So that the hole of the ball and the valve overlap or vertical centerline of the channel, to achieve the valve fully open or fully closed action, usually working in harsh environments. Bola de válvula de carburo de tungsteno with high hardness, wear resistance, corrosion resistance and high temperature, etc., and therefore mainly used in all kinds of sealing work, such as: pump, thermal power plant ash slagging water systems, fluid seal rotating ball.

Bola de válvula de carburo de tungsteno for conventional pump
Valve ball, the role of a one-way valve to control the flow of oil flow, is in a very poor conditions of work. Multi-component working medium is air, water, oil, sand, wax, resin and asphalt, is a random change and non-uniform three-phase medium. Pumping liquid carry some mechanical impurities at high speed flows violently scour the ball, the ball and seat, has produced hit between the hood, a large quantity of oil wells in the sand, make the ball and seat sealing surface between the damage more rapidly, this damage is a mechanical wear. In most wells all contain corrosive medium, which valve bal is particularly serious corrosion damage. Crude oil contains H2S, Cl- ,salt, alkali and other,so chemical or electrochemical reactions can occur with metal, the metal from corrosion. In the dual role of mechanical abrasion and chemical corrosion, precision ball and seat drop, sealing destroyed, its performance for many irregular surface pitting, flaking, mesh ditch, thereby enabling the valve is fully failure, significantly decreased pump efficiency. Make tungsten carbide as the main material can better adapt to pump operating conditions. Obviously, for the harsh conditions pump, manufactured with Bola de válvula de carburo de tungsteno valve is an ideal material. In short, Bola de válvula de carburo de tungsteno used in pump, both in diluted oil, or heavy oil, high sand, wax wells, or wells rich in corrosive media,will produce good results, and will have a broad application prospect.

The performance of Bola de válvula de carburo de tungsteno
1. Good physical properties. Bola de válvula de carburo de tungsteno has characteristics of high hardness, strong resistance level impact, high temperature resistance, erosion, high abrasion (wear resistance of 15 to 20 times higher than the best high-speed steel).
2. Chemical stability. Bola de válvula de carburo de tungsteno is antioxidant, anti-corrosion to a variety of media (acid, alkali, salt, various gases, etc.) .
3 Density. The proportion of tungsten carbide is16.5-18.75g/cm3,higher than the proportion of steel increased by more than 70%, the whereabouts of the ball will significantly improve the speed, make the performance improved, and is conducive to the normal operation of the valve of the ball.
4 The life of Bola de válvula de carburo de tungsteno is higher than ordinary steel valve ball , and it is widely used in petroleum, chemical and power industries.

Bola de válvula de carburo de tungsteno sphere finishing
Bola de válvula de carburo de tungsteno as the opening and closing parts of the seal, Bola de válvula de carburo de tungsteno the should have a sealing surface , roundness and roughness of Bola de válvula de carburo de tungsteno influnt the sealing performance, the ball must be spherical surface finishing. Improve grinding efficiency Bola de válvula de carburo de tungsteno requires the use of closed milling method. Composite slurries and composite abrasive can effectively improve the grinding media and abrasive grinding attachment capability and efficiency of the Bola de válvula de carburo de tungsteno. The quicklier Platen speed, and higher the pressure, the higher processing efficiency, but at the same machining accuracy may decline. Roughing to finishing, grinding disc speed, pressure from high to low choice. Bola de válvula de carburo de tungsteno of the final precision decision on ball roundness control process and the surface roughness of the beginning of the research and precision lapping process.

Bola de válvula de carburo de tungsteno cost is higher, but due to the life of Bola de válvula de carburo de tungsteno higher than steel valve ball several times, can better adapt to the harsh working conditions in the underground, and would reduce leakage and improve pump efficiency and prolong pump inspection cycle , thus the increase in crude oil prices, operating costs savings far ccover the cost of increasing the number of Bola de válvula de carburo de tungsteno . Thus, making use of Bola de válvula de carburo de tungsteno has a very substantial economic benefits.
