Counter-type check valve, use and structural features
The way of the clip type check valve The check valve is installed in the piping system and its main function is to prevent backflow of the medium. The check valve is an automatic valve that is opened and closed by the pressure of the medium. The clamp type check valve is suitable for the nominal pressure PN1.0MPa~42.0MPa, Class150~25000; nominal diameter DN15~1200mm, NPS1/2~48; working temperature -196~540°C for various pipelines, used to prevent The media is reversed. By using different materials, it can be applied to various media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and uric acid. The main material of the clip type check valve: Standards and specifications for wafer check valves Structural features of the check valve
Shilu Huanglian is mainly produced in the primeval forest area of Dafengpu, Huangshui National Forest Park, Huangshui Town, Shizhu County. The unique climate, water quality and soil conditions in this area are the best growth areas for Shiluo Huanglian. In 1991, the Ministry of Agriculture Investment in the establishment of the National Yellow River Huangpi GAP demonstration base, the town has also established China's largest Coptis market. Natural plant Raw materials Agricultural products are not any additives. Traditional Huanglian kang, baking with firewood, drying, hair removal with bamboo cage trough, the species are hand-selected, remove the impurities and minced, relatively clean.
