With the rapid development of industrial production, China’s valves are more and more widely used in various fields, and their performance and quality directly affect the safe and stable operation of equipment and systems. Therefore, in the purchase of Chinese valves, we must be careful to ensure that the purchase of the right Chinese valves. This article will from the Chinese valve type, performance, selection, installation, maintenance and other aspects, detailed introduction of the Chinese valve purchase precautions and suggestions, to help users better understand the Chinese valve, to buy high-quality Chinese valve products.
First, Chinese valve type and performance
1. Chinese valve type
Chinese valves can be divided into many types according to the structural form, driving mode, use, such as gate valves, globe valves, ball valves, butterfly valves, safety valves, pressure reducing valves, etc. Different types of Chinese valves have different characteristics and scope of application, users in the purchase of Chinese valves, need to choose the right type of Chinese valves according to the actual needs and conditions of use.
2. Chinese valve performance
The performance of China’s valves mainly includes sealing performance, flow performance, opening and closing performance, pressure resistance and so on. When purchasing Chinese valves, users need to pay attention to the performance indicators of Chinese valves to ensure that Chinese valves can meet the needs of practical applications.
Second, China valve selection
1. Choose according to Chinese valve type
When selecting the Chinese valve type, it is necessary to comprehensively consider the working pressure, temperature, medium, flow rate and other factors of the Chinese valve to choose the appropriate Chinese valve type. For example, for high pressure, high temperature, corrosive media, you can choose gate valves, ball valves, etc.; For low pressure, normal temperature, non-corrosive media, you can choose the globe valve, pressure reducing valve, etc.
2. Select according to Chinese valve size
When choosing the size of China’s valve, it is necessary to choose the appropriate size of China’s valve according to the pipeline size, flow capacity, working pressure and other factors. China’s valve size selection is too large, will lead to China’s valve operation instability; The size selection of China’s valve is too small, which will cause China’s valve to not work properly.
3. Choose according to Chinese valve material
In the selection of Chinese valve material, it is necessary to choose the appropriate Chinese valve material according to the nature of the medium, working temperature, Chinese valve type and other factors. For example, for highly corrosive media, you can choose stainless steel, alloy steel and other materials with good corrosion resistance; For high temperature and high pressure media, you can choose superalloy, carbon steel and other materials.
Third, China valve installation
1. Installation direction
The installation direction of the Chinese valve should be consistent with the flow direction of the fluid to ensure the normal operation of the Chinese valve.
2. Installation position
The installation position of the Chinese valve should be easy to operate and maintain, and should not affect the normal operation of the equipment.
3. Install the environment
The installation environment of China’s valve should be dry, ventilated, and should not be affected by direct sunlight, rain, etc.
Four, China valve maintenance
1. Check regularly
Users should regularly check the use of Chinese valves, find abnormal situations in a timely manner.
2. Clean and maintain
Chinese valve in the process of use, may be polluted by dust, impurities, etc. Users should regularly clean and maintain the Chinese valve to ensure the sealing performance and flow performance of the Chinese valve.
3. Lubrication maintenance
For Chinese valves that need lubrication, users should regularly fill lubricants to ensure the opening and closing performance of Chinese valves.
In short, when purchasing Chinese valves, users need to choose the right Chinese valves according to the actual needs and conditions of use, considering the type, performance, size, material and other factors of Chinese valves. At the same time, when installing and maintaining the Chinese valve, it is also necessary to operate in strict accordance with the relevant requirements to ensure the normal operation and service life of the Chinese valve.
