The Choice Of Forged Steel Ball Valve Is Usually Made Under High Pressure Working Conditions
3 Piece Threaded Ball Valve is used for long-distance pipelines and general industrial pipeline operations. It is a high-performance ball valve. Due to its superior performance, it is used in many industries. High-pressure ball valves are safe and can be used in harsh environments and highly corrosive media, so they are very popular in the industry. So, what problems should be paid attention to when using high-pressure ball valves? Let's take a look at it together.
1. During operation, pay attention to whether the pipeline has been flushed and unobstructed, and whether the ball valve has been cleaned. The operation of the high-pressure ball valve should be carried out according to the instructions, especially for novice operators. The valve stem should be rotated according to the signal input by the actuator to complete the required action. The high-pressure ball valve rotates 1/4 circle in the forward direction to close the valve, and rotates 1/4 circle in the reverse direction to open the valve.
2. If there is a fault during use, you must know how to repair it. Although the service life of the high-pressure ball valve is relatively long and the repair probability is relatively small, it is precisely because it does not often fail, so once a failure occurs in production, it is very important to know how to repair it. When a fault occurs, it depends on whether the pipeline pressure is normal. Generally, it is caused by excessive pipeline pressure. Appropriate exhaust or increasing the ball valve outlet will reduce the fault.
3. After the high-pressure ball valve is used, it should be cleaned, the power supply and gas source should be disconnected, and the pressure of the valve when it is not in operation should be reduced. This will help to increase the service life of the high-pressure ball valve and also help to improve the precision.
The above are some issues that should be paid attention to when using high-pressure ball valves. Of course, it should be emphasized that when cleaning or installing, the bolts on the flange must be installed symmetrically and step by step. Everyone must pay attention to this.
I believe that many people have heard of high-pressure ball valves, but some people may not know much about its advantages. In fact, high-pressure ball valves have many advantages. It is precisely because of its many advantages that many industries are using it. However, if you don’t understand its advantages, you may not be able to maximize the advantages of the product. Let’s take a look together!
1. Easy maintenance
Many users use high-pressure ball valves, which has a lot to do with its easy maintenance. Because the structure of the ball valve is relatively simple and the sealing ring is also movable, it is more convenient to disassemble and repair.
2. Simple structure
When you see the high-pressure ball valve, you can know that it is a product with simple structure, small size and light weight. It is also very convenient to use.
3. Tight and reliable
The high-pressure ball valve has a feature that it has two sealing surfaces, and the sealing surface materials of the ball valve are wide, and various plastics can be used. In addition, its sealing performance is very good, it can be completely sealed, and it can also be used in vacuum systems.
4. Wide range of applications
The scope of application is very wide. Its diameter ranges from a few millimeters to confidential, and it can be used in both high vacuum and high pressure environments.
5. Convenient operation
Open and close quickly, only need to rotate 90 degrees to achieve from full open to closed, and it is also convenient for long-distance control.
6. Low fluid resistance
The fluid resistance of the high-pressure ball valve is very small, even the full-diameter ball valve has no flow resistance.
It can be seen that there are many advantages of buying a high-pressure ball valve. If you want to use or buy a high-pressure ball valve, users need to pay attention to choosing a regular manufacturer and choosing a product with guaranteed quality.
Every time I hear people say that the application range of high-pressure ball valves is very wide, but some people may not know much about the specific industries in which high-pressure ball valves are used. 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 the valve seat
When the stagnation pressure in 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 result in 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, which can reduce the operating torque problem.
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.
