Possessing More Advantages Tungsten Carbide Ball Better Than Traditional Valve

Carbide ball, commonly known as tungsten steel ball, refers to the use of carbide for the material made of beads, balls, carbide ball high hardness, wear, corrosion resistance, bending, the use of harsh environment, can replace all steel Products. Commonly known as tungsten steel ball, is made of cemented carbide made of beads, balls, carbide ball high hardness, wear, corrosion resistance, bending resistance, the use of harsh environment, can replace all steel products.

Composition
The tungsten carbide ball is based on a high hardness refractory metal carbide (WC, TiC) micron powder, with cobalt (Co) or nickel (Ni), molybdenum (Mo) as a binder, in a vacuum furnace or Powder metallurgy products sintered in a hydrogen reduction furnace, currently available in the series of hard alloys YG, YN, YT, YW.
Category
Tungsten carbide balls mainly include blank balls, fine grinding balls, punching balls, bearing balls, valve balls, non-magnetic balls, Monel balls, through-hole balls, measuring balls, scratching balls, and ball beads.

Reference Illustrate:

The main advantages of cemented carbide ball valves can be divided into the following aspects:

1. It has the theoretically lowest flow resistance (flow resistance refers to the ratio of the pressure difference applied to both sides of the sample of sound absorbing material to the linear velocity of the gas stream passing through the sample in a steady state of gas flow);

2. Excellent chemical stability, wear resistance and corrosion resistance, can be in contact with most liquids and some corrosive media;

3. In the high temperature and high pressure environment, it can still achieve complete sealing (nominal pressure from vacuum to 42MPa);

4. Since the carbide ball valve uses the sphere as the opening and closing member, it is less affected by the friction force, and can be quickly opened and closed (can be controlled within 0.05-0.1 s), and the impact of operation is small. In addition, the spherical closure The piece can withstand a high pressure difference when closed, and can also achieve automatic positioning;

5. It has two-way sealing, which makes the work more stable and reliable;

6. When fully open or fully closed, the sealing surface and the medium of the ball and the valve seat are completely isolated, which makes the high-speed flowing medium not cause the valve seat to be corroded due to contact with the seat sealing surface for a long time;

7. The overall weight is lighter and the structure is more compact, which is suitable for high temperature medium system and low temperature medium system (operating temperature range -204 °C - 815 °C);

8. The valve body has a symmetrical structure, so that it can withstand the pressure from the pipeline well;

9. The ball valve of the whole welded valve body can also be buried directly in the ground, so that the valve internals are not eroded. It is the most ideal valve type in oil and natural gas pipelines, and the maximum service life can reach 30 years.

In addition, to ensure the stability of the carbide ball valve, the choice of carbide ball valve seat seal material is also one of the key elements can not be ignored. It is required to have a small friction coefficient, stable physical and chemical properties, wide temperature application range and good sealing performance. Among the more common materials include tetrafluoroethylene (PTFE), nylon, and some synthetic rubbers. However, these materials have certain defects. For example, tetrafluoroethylene has a high coefficient of thermal expansion, poor thermal conductivity, and insufficient sensitivity to temperature. When the sealing material becomes hard, its sealing property is also reduced. It is when the pressure difference is low. Some synthetic rubbers are limited in the range of use of the medium and temperature. If the corresponding lubricant is not added, the phenomenon of seizure is likely to occur.

Feature
Cemented carbide balls have high hardness, wear resistance, corrosion resistance, bending resistance and harsh environment, which can replace all steel ball products. The hardness of the cemented carbide ball is ≥90.5, and the density is 14.9 g/cm3.

Use
Carbide balls are used in a wide range of applications, such as precision punching, precision bearings, instruments, instruments, pens, sprayers, pumps, mechanical parts, sealing valves, brake pumps, punching holes, oil fields, Hydrochloric acid laboratory, hardness measuring instrument, fishing gear, counterweight, decoration, finishing and other high-end industries!
