In Which Industries Can High Pressure Ball Valves Be Used?

Every time I hear people say that the application scope of 1 Piece Threaded Ball Valve is very wide, but some people may not know much about the specific application industry of high-pressure ball valves. In fact, it can be used in various industries such as petroleum, chemical industry or thermal power station, and it is applicable to many media, which has a lot to do with its characteristics.

1. Prevent the expansion of fire

Some users may have doubts about this. In fact, when a fire occurs, the high-pressure ball valve will cause the valve seat seal ring to be damaged or even softened due to abnormal high pressure. At this time, under the pressure of the spring and the medium, the spherical surface of the support ring and the ball will form metal-to-metal contact, which can play a temporary sealing function and prevent the expansion of the fire.

2. Automatic reset of valve seat

When the stagnation pressure of the middle cavity of the high-pressure ball valve is abnormal, especially when it exceeds the spring preload, the valve seat of the high-pressure ball valve will automatically detach from the ball, which will have an automatic pressure relief effect, but the valve seat will also automatically reset after the pressure relief.

3. Reduce operating torque

The packing gland of the high-pressure ball valve uses a double sealing ring, which is especially suitable for gas media, and the packing can be installed in the packing plate, so that the operating torque problem can be reduced.

Due to these characteristics of the high-pressure ball valve, it can be used in multiple industries. Of course, if we want the product to be put into use normally without problems, we must choose products with guaranteed quality, so as to reduce the failure rate of the product and avoid too many problems in the use of the product.

After the high-pressure ball valve has been used for a long time, it is inevitable that the valve will be corroded. If the valve is corroded, we may need to replace it with a new product. For the valve, which is the most easily corroded part, what preventive measures do we need to take? Prevent valve corrosion, use it for a longer time, and reduce the cost of our product use. So, how to avoid the corrosion of the valve of the high-pressure ball valve?

1. Treat the metal surface

The valve of the high-pressure ball valve is metal and is easily corroded, but if we treat the metal surface of the valve, the corrosion resistance of the valve can be improved. There are many ways to improve corrosion resistance, such as using nitriding or boriding waterproofing for surface treatment.

2. Use appropriate corrosion-resistant materials according to the corrosive medium

In the production process, medium corrosion is relatively complicated. Even if the same medium is used, different valve materials are used. The influence of factors such as medium concentration and temperature will also lead to different material corrosion. Specifically, we need to make corresponding adjustments according to the valve materials we use, understand various corrosion causes, and deal with them in a targeted manner.

3. Spraying paint

This is the most commonly used anti-corrosion measure, especially anti-corrosion paint is often used in valve products. Generally, anti-corrosion paint is configured using synthetic resins, vegetable oils or solvents. When this paint is used to cover the metal surface, it can isolate the medium and the atmosphere, and can achieve a good anti-corrosion effect.

In addition to the anti-corrosion measures for high-pressure ball valves introduced above, thermal spraying, electrochemical protection, and the addition of corrosion inhibitors can also be used to extend the time the product is corroded. During use, users should check regularly so that they can find product problems in time and deal with them in time.
