What parameters should the valve know? It can correspond to the corresponding specifications and mod

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

For specifications, you need to provide the size of the pipe.

Valves are control components in fluid transportation systems, which have the functions of shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. So, what are the basic parameters of the valve? The basic parameters of the valve are mainly nominal diameter, nominal pressure, pressure and temperature level, etc.

1. Nominal diameter. The nominal diameter refers to the nominal diameter of the connection between the valve and the pipe, which is expressed by dn and number. Such as DN150, it means that the nominal diameter of the valve is 150mm, which is the main parameter of the valve.

2. Nominal pressure. Nominal pressure refers to the design given pressure related to the mechanical strength of the valve, which is the maximum allowable working pressure of the valve at the reference temperature, expressed by pn and number. For example, it indicates that the bearing capacity of the valve is the main parameter of the valve.

3. Pressure and temperature level. When the operating temperature of the valve exceeds the reference temperature of the nominal pressure, its working pressure must be reduced accordingly. The operating temperature of the valve and the corresponding large working pressure change are referred to as the "pressure stabilization gauge", which is the benchmark for valve design and selection.

Because the temperature of the equipment and facilities using valves in the oil depot is within the reference temperature range, the temperature and pressure level can be disregarded.

The valve specification and model comparison table is used to provide customers with different valve specifications and detailed models, so that customers can choose to solve engineering needs.

Typically, it will include information about the size of the valve body, the diameter of the valve, the material used in the valve, the fluid pressure, the temperature, and the structure of the rubber.

When purchasing a valve, the comparison table of the valve specifications and round models also helps the customer to understand how the valve is opened, as well as the characteristics and functions of the valve.

It can also be used to help customers select the best valve for more efficient and precise application results.

In addition, pneumatic valve specification and model comparison tables are becoming more widely used, providing more and more advanced control parameters for new electronic and data-driven valves, such as control signals, safety controls and feedback sensing information, as well as appropriate control strategies for different use cases.

Valve model compilation method, valve number description The valve model should usually indicate the valve type, driving mode, connection form, structural characteristics, nominal pressure, sealing surface material, valve body material and other elements. The standardization of valve models provides convenience for the design, selection and distribution of valves. Today's valves are available in more and more types of types and materials, and the preparation of valve models is becoming more and more complex.

Although China has a unified standard for the preparation of valve models, it can gradually not meet the needs of the development of the valve industry. At present, valve manufacturers generally adopt a unified numbering method; If the unified numbering method cannot be adopted, each production plant can formulate a numbering method according to its own situation.

The valve model compilation method stipulates the valve model preparation, valve type, driving mode, connection form, structural form, sealing surface material, pressure and valve body material code and code representation method. The valve model compilation method is suitable for all kinds of gate valves, globe valves, throttle valves, butterfly valves, ball valves, diaphragm valves, plug valves, check valves, sewage valves, plunger valves, pressure reducing valves, trap valves, safety valves and pipeline valve products.
