Tungsten Carbide Valve Ball

Tungsten Carbide Valve Ball Picture

Tungsten carbide valve ball 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. tungsten carbide valve ball 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.

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 tungsten carbide valve ball valve is an ideal material. In short, tungsten carbide valve ball 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.

Tungsten carbide valve ball cost is higher, but due to the life of tungsten carbide valve ball 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 tungsten carbide valve ball . Thus, making use of tungsten carbide valve ball has a very substantial economic benefits.
