Trunnion mounted ball valves are designed for upstream sealing. The load generated by the line fluid on ball is absorbed by the trunnion bearings and is directly transmitted to the valve body, and the upstream seat driven by medium pressure drifts towards the ball to creater reliable sealing. The seat design has a built-in automatic cavity relief mechanism.

In the process of rapid industrialization and urbanization, China's food consumption demand will grow rigidly, while the reduction of cultivated land, water shortage, climate change and other restrictions on food production become increasingly prominent, and the environmental cost of food production is increasing. The basis of food security is still More fragile. We must adhere to the basic self-sufficiency of food security in the country, focus on improving the comprehensive production capacity of grain, speed up the construction of a food security system in line with China's national conditions, ensure food security, and provide solid support for achieving the goal of building a well-off society in an all-round way. 
Create an integrated grain and oil processing system to ensure national food security
[China Agricultural Machinery Network Industry News] Since the reform and opening up, China's grain comprehensive (market zone) production capacity has steadily increased, food supply has become increasingly rich, with nearly 9% of the world's cultivated land, 6.5% of water resources, a stable solution to more than one billion people. The problem of eating has achieved universally recognized achievements.
Qingdao, Shandong: Want to build an integrated grain and oil processing system
Recently, Qingdao City is introducing a large range of grain and oil testing equipment, and is fully committed to building a grain and oil testing center to achieve grain and oil supervision. At the same time, actively build an information management system to ensure the quality of grain and oil entering the warehouse. In the future, we will purchase grain and oil processing equipment, transportation equipment, distribution equipment, etc., and we will build an integrated grain and oil processing system.
On June 1st, Shandong Province's grain storage military supply management station visited Qingdao. It is reported that Qingdao City actively constructs a food security guarantee system that is in line with Qingdao's actual and useful conditions, and implements grain and oil inspections for grain and oil entering the market, and realizes grain and oil supervision. Let the people eat the food.
According to reports, Qingdao has built a food security system to ensure the safety of food quality. We will establish a quality inspection center in the grain and oil market to achieve the supervision of grain and oil quality in the market, and insist on ensuring that we will meet the requirements for entry and inspection. Invested 20 million yuan to rebuild the city grain and oil quality testing center, with an area of ​​3,000 square meters, equipment and equipment assets of 10 million yuan, with 2,466 grain and oil parameters testing capabilities, was identified as the national grain and oil standard verification workstation.
On the morning of the 1st, the observation group visited the construction of the intelligent grain depot in Qingdao's second grain depot, and affirmed Qingdao's creation of a smart food system. It is reported that Qingdao is accelerating the construction of a comprehensive platform for grain information management in the city and building a smart grain depot. Invested more than 10 million yuan, promoted the construction of a comprehensive platform for grain information management in the city, carried out information transformation on 24 grain storage and storage points, promoted food identification applications in 56 raw grain storage and processing enterprises, and initially established a grain quality traceability system. The intelligent grain storage and digital grain storage have built a food management information system with advanced facilities, scientific management and intelligence.
It is understood that Qingdao Municipality is also actively building a food emergency response system to ensure food security. Planning a food emergency network integrating reserve, processing, transportation, supply and distribution, the government issues emergency plans for food emergencies, and organizes emergency drills every year. Invest 60 million yuan to build 10 food emergency distribution centers and 10 staple food distribution centers.
China will accelerate the development of food research, design and industrial integration
Recently, it was learned from the National Grain Bureau that China will accelerate the development of integrated food research, design and industry.
The State Grain Administration has recently issued guidance on deepening the reform of the grain science and technology system and accelerating the construction of science and technology innovation systems in the grain industry, and clearly proposed to accelerate the promotion and application of food science and technology achievements. Increase the promotion of science and technology services. Adhere to the "advanced, applicable, reliable, safe, economical, and effective" standards, and select mature scientific research results. In accordance with the laws of science, in accordance with the state's promotion and application of new technologies, new equipment related policies and regulations, the development of scientific and technological achievements in the grain industry. Explore the pilot project of “Science and Technology Commissioner†in the grain industry to strengthen post-harvest technology services in rural areas.
The overall goal of the opinion is: new breakthroughs have been made in the reform of the grain science and technology system, closely following the development of the industry, making food science and technology innovation more focused on national goals, major tasks and industry needs; reforming the way of scientific and technological innovation to ensure that food research projects and fund allocation are more standardized Reasonable; improve the incentive mechanism for food science and technology innovation; accelerate the development of scientific research, design and industrial integration, and promote the promotion and application of food science and technology achievements.
According to the opinions, we will focus on major scientific and technological problems in food conservation and depletion, food quality and safety, ecological and safe grain storage, modern food logistics, grain and oil processing value added, and grain monitoring and early warning.
