The Mid-Autumn Festival is one of the four traditional festivals in China. On the day of the Mid-Autumn Festival, people in different places have different customs and celebrations, but they all place their infinite love for life and yearning for a better life. So, how does DERVOS celebrate the Mid-Autumn Festival? Bo Bing is an important folk competitive game custom in Fujian. The rule is that everyone rolls the dice in turn and receives the corresponding prize according to the number of dice. At 2:00 pm that day, everyone got ready to draw lots early. According to the result of the draw, we were divided into three tables. With excited cries and laughter, the prepared prizes were gradually won by everyone. Finally, the CHAMPION was won by West, Sheila and Rico. They are so lucky! After the Bo Bing, we went to Eric's house together. This time, we planned to have a "different dinner". We were still divided into three groups according to the results of the draw of Bo Bing, and each group prepared an adept cuisine. After discussion, the first group led by Eric prepared the Northeast specialty: Stewed in Iron Pot; the second group led by Ken was ready to make a hotpot that everyone loves; the third group led by Holly prepared luxurious seafood dishes! With a big direction, everyone was busy, cleaning, arranging the site, preparing food, cooking... everyone was in an orderly way! Finally, after a few hours of hard work, all the dishes of the three groups were finished. They looked very appetizing! And they were so delicious and sweet! It was a very successful meal! After dinner, we arranged another surprise activity, “A Surprise Bo Bing”! Different from the previous one, this Bo Bing set up "Easter eggs": Catwalk Show, Hot Dance Show, A Cup of Special Drink, No Hands to Eat Apples. They showed us the other side beyond work with confidence, joyful and passion. DERVOS always full of surprise. It's the show time! The Mid-Autumn Festival in DERVOS ended with laughter and laughter, a new tomorrow will come as scheduled! Work hard, play hard, DERVOS people takes care of work, life and every day!

Difference Between Ball Valve and Traditional Valve
2022-09-01

Valves are widely used and have many kinds. Ball valve is one of the most important valve products. Next, Dervos will introduce the difference between ball valve and traditional valve! Comparison between ball valve and traditional valve: 1. From the perspective of energy conservation and environmental protection, the ball valve is an energy-saving product. It has good circulation capacity and small flow resistance, which is very important in engineering application. 2. The ball valve has the advantages of small fluid resistance, quick and convenient opening and closing, small external size, light weight, good sealing, long service life, high safety and reliability, and convenient maintenance. Moreover, it is welcomed for its characteristics of self pressure relief and ball cleaning. 3. The opening and closing stem of the ball valve performs rotary motion. Compared with the linear motion valve, it is convenient to open and close and easy to realize the automation of valve operation. 4. It can be used for various media, pressure and temperature conditions, and the valve diameter range is also expanding. In recent years, with the breakthroughs in new structure, new materials and processing technology, ball valves are used more and more widely, and the market share increases year by year. It is one of the fastest developing valve varieties.
