This standard (JB/T9092) is a revision of ZBJ16006-90 "Testing and Inspection of Valves".

The main technical differences between this standard and ZBJ16 006-90 are as follows:

1. Change the name of the standard to "Inspection Requirements for Valves"

2. Add the terms' one-way seal and two-way seal '

3. The regulations for the "necessary tests" of valves are specified separately for each size based on nominal pressure and nominal capacity

4. The test items for gate valves and globe valves are specified separately

5. The minimum duration of shell and seal tests for butterfly valves has been modified to be consistent with other valves

6. The minimum duration of the sealing test on the valve has been modified

7. The maximum allowable leakage for the sealing test has been modified according to the requirements of API 598-96

8. Modified the test method for low-pressure sealing test

term

Unidirectional sealing: After the valve is closed, the medium must enter from one direction at both ends of the valve in order for the sealing pair of the valve to remain sealed

Bidirectional sealing: Regardless of which direction the medium enters from both ends of the valve, the valve sealing pair can maintain sealing after the valve is closed

With the improvement of people's living standards, more and more users in the valve industry attach great importance to the industry and have put forward many needs and suggestions. Therefore, meeting user needs will be the foundation of the industry.

In recent years, the valve industry has changed from the traditional mode to the Internet convergence mode. With the exploration and sinking of major platforms in the industry to third - and fourth tier cities, enterprises integrate the entire process from supply to production and after-sales, and use industry empowerment as a link to provide comprehensive support for many high-quality companies in brand, design, system, supply chain, and other aspects.

The new technology scene in the valve industry enables industry users to have a better experience. The support of technology enables the service effectiveness and products of the industry to be favored by users. The emergence of new technologies such as cloud computing, big data, and artificial intelligence provides a new space for thinking about industry standardization issues. By incorporating new technologies into the production and service processes of the industry, it can better solve industry pain points and problems, ensure industry service effectiveness, and achieve dual improvement in industry efficiency and user experience.

The valve industry is experiencing an increase in financial demand, such as industry loans, as the consumer base becomes younger. A company has launched a cooperation between consumer and banking institutions in the valve industry, delving into the industry's ecological financial scenarios and focusing on upgrading payment management. Continuously focus on financial scenarios. The advantages of leveraging supply chain finance are obvious, achieving efficient integration between financing enterprises and financial institutions, helping small and medium-sized enterprises overcome financing difficulties, and improving the operational efficiency of the industrial chain.

The informationization of the valve industry is highly favored by users. Enterprise B uses the Internet to integrate the characteristics of the valve industry through informatization, improve the user experience, and bring many convenience to users. This will be an inevitable trend in the future development of the industry.

Industry characteristic analysis

By comparing valve attributes and core service models, the overall valve industry in China can be divided into five categories. They are innovative valves, venture capital valves, media valves, industrial valves, and service-oriented valves. In addition, as the valve industry is still in its early stages of exploration, the overall service and operational models are not fully mature. There are also composite valve types such as industry+entertainment, venture capital+gaming, etc. With the policy dividends of mass entrepreneurship and innovation fading out of the industry stage, valve service types are returning to their commercial essence. How to rely on one's own operational capabilities to achieve stable development in the industry, in order to achieve investment returns or commercial landing, has become a core issue for discussion in the industry. Among various types of valves, industrial valves are mostly led by enterprises and closely integrated with their business operations. So it has higher commercial feasibility for implementation. Becoming one of the core exploration directions in the industry.
