In addition, if the sealing surface of the product has rust or wear, it must be processed by machinery. If the valve seat is seriously damaged, it must be replaced in time.
3. Consumable parts
The packing and sealing gaskets of the forged steel ball valve need to be regularly inspected and replaced within a certain period of time. Moreover, if the valve core and diaphragm are cracked or aged, they must be replaced according to the situation, but the diaphragm must be replaced after two or three years of use.
Regarding the maintenance precautions of forged steel ball valves, I hope that the above introduction can bring some help to everyone. In addition, the forged steel ball valve should be cleaned once a year to avoid contamination of the valve seat cavity, so that the valve seat can move more freely. It should also be noted that regularly injecting grease into the switch can reduce the friction between the valve ball and the valve seat.
Forged steel ball valve is a valve product that is widely used in many industries. Due to its excellent performance, it is purchased and used by many companies. But do you know what are the advantages of forged steel ball valves? Let me give you a brief introduction below.
1. Strong anti-sulfurization and anti-cracking capabilities. The material of the forged steel ball valve in contact with the medium is a high-tech material that meets international standards, and the surface is nickel-plated, which can meet the requirements of working in a high-sulfurization environment.
2. The valve of the forged steel ball valve is made of polymer materials or alloys, which has the performance of high temperature and high pressure resistance, and is suitable for the transmission and throttling of many media. And because of the special material, it has strong corrosion resistance, long life, and a wide range of applications.
3. Not only is the valve made of corrosion-resistant materials, but even the valve seat is made of special materials, and this material is polytetrafluoroethylene, which is inert to almost all chemical substances, so it can maintain sealing for a long time. Due to its strong inertness, it has stable performance, is not easy to age, and can be used for a long time.
4. Forged steel ball valves are generally symmetrical, so they can withstand strong pipeline pressure, and the position is not easy to change. Whether it is fully open or half-open, it can play a good role in the proper sealing, and there will be no adhesion when conveying viscous liquids.
The above are some of the characteristics of forged steel ball valves. Although the above content has not listed all the characteristics, people in the industry know that this is a valve with very good working performance. If companies that transport liquids also need to install valves, they may consider it.
What are the advantages of high-pressure ball valves? Awesome, so many!
I believe that many people have heard of high-pressure ball valves, but some people may not know much about its advantages. In fact, there are many advantages of high-pressure ball valves. 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!
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 easier to disassemble and repair.
2. Simple structure
When you see the high-pressure ball valve, you can know that it is a product with a simple structure, small size, and light weight. It is also very convenient for us to use.
3. Tight and reliable
One feature of the high-pressure ball valve is that it has two sealing surfaces, and the sealing surface material of the ball valve is 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. Small 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.
High-pressure ball valves are used for long-distance pipelines and general industrial pipeline operations. They are high-performance ball valves. Due to their superior performance, they are used in many industries. High-pressure ball valves have good safety 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 fault occurs in production, it is very important to know how to repair it. If 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. The high-pressure ball valve should be cleaned after use. The power supply and gas source should be disconnected to reduce the pressure of the valve when it is not in operation. This will help to increase the service life of the high-pressure ball valve and also help to improve precision.
The above are some issues that need to 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.
Every time I hear others say that the use range of high-pressure ball valves is very wide, but to specifically talk about the use industry of high-pressure ball valves, some people may not know much. In fact, whether it is in various industries such as petroleum, chemical industry or thermal power station, it can be used, and it has a lot of applicable 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 resetting of valve seat
When the stagnant 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. However, 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 tray, which can reduce the operating torque problem.
Due to these characteristics of the high-pressure ball valve, it can be used in many 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.
5. How to prevent the valve of the high-pressure ball valve from being corroded
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 and use it for a longer time, which can also reduce the cost of our product use. So, how to avoid the corrosion 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 boronizing waterproofing for surface treatment.
2. Use suitable corrosion-resistant materials according to the corrosive medium
In the production process, medium corrosion is relatively complicated. Even if the same medium is used, the valve materials used are different, and the influence of factors such as medium concentration and temperature will also cause different material corrosion. Specifically, we need to make corresponding adjustments based on the valve materials we use, understand various corrosion causes, and deal with them in a targeted manner.
3. Spray 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 corrosion time of the product. During use, users should conduct regular inspections so that product problems can be discovered and dealt with in a timely manner.
