Explore the use of various check valves in backflow prevention Import check valve, (VCT, Check valve), alias: import check valve, inlet bottom valve, inlet check valve, simple description is to prevent the medium backflow valve. Although simple, different check valves have different uses. 1. Check valve for high pressure applications. High-pressure steam pipe used in power plants, the pressure can reach 32Mpa, or 2500LB. The connection method is generally welded. It is called imported welding type imported check valve. Generally, the forged valve body is used. The self-sealing structure is called imported forged steel. Check valve. 2, the use of American standard design and American standard flange structure, suitable for the use of US oil standard API or ANSI standard check valve, the use of imported American standard check valve, the main grades are 150Lb, 300Lb, 600Lb, 1500Lb. 3, small pipe diameter, low pressure, corrosive medium pipe, generally use internal threaded check valve, stainless steel 304, 316 material, that is, imported internal thread check valve. 4. The check valve in the vertical pipeline can be imported vertical check valve. 5. Hydraulic system, or small-diameter high-pressure pipeline, adopts imported through-way check valve. 6. At the bottom end of the suction pipe of the pump, a check valve with a filtering function is required to automatically prevent the fluid from flowing backwards, and to prevent impurities from entering the pump pipe. At this time, an imported stainless steel bottom valve is used.
Organic mung bean starch is a kind of powder formed by the precipitation of mung bean after soaking and grinding with water. Our organic mung bean starch follows the traditional processing ideas and combines modern industrial technology to achieve a more efficient, safer, and more hygienic processing level. The characteristics of mung bean starch are sufficient stickiness, low water absorption, white and shiny color.
Mung bean (Vigna radiata) is a plant in the legume family. Mung beans are mainly grown in India, China, and Southeast Asia. The Chinese have grown mung beans for nearly 2,000 years. They are ubiquitous in China, and there are many types, and numbers. Mung beans are also grown in other countries/regions in South Asia, North America, Brazil, and Europe. The main provinces for mung bean cultivation in China are Anhui, Henan, Hebei, Hubei, Liaoning, Shanxi, Shaanxi, and Sichuan.
The nutritional value of mung bean starch is very high, and its uses are also very wide. For example, mung bean starch has antibacterial, antibacterial, hypolipidemic, antitumor, and detoxification effects.
Mung bean starch contains a considerable amount of oligosaccharides (pentosan, galactan, etc.). These oligosaccharides are difficult to be digested and absorbed because the human gastrointestinal tract does not have a corresponding hydrolase system, so mung bean starch provides a lower energy value than other grains and has an adjuvant therapy effect for obese and diabetic patients.
