Product Description

1.background of technology development In mining, urban, sewage treatment, water supply, industrial process of cooling water circulation device, commonly used in the past is slow closing check valve, globe-type pump control valves, butterfly valves for pumping hydraulic control valves used to meet the automatic pumping control, reduce labor intensity of the request, But the life of that kind of product is short , stopping the pump vibration, noisy, oil polluted , easy to plug (poor mining), making it difficult for large diameter, they take large space .having great resistance and other problems .they are energy-sapping . This product is a new control valve products, which take full advantage of its medium pressure pipeline to automatically open and close, especially using the latest technology cylinder (gas spring) as the control cylinder, The automatic pumping meet the control requirements, especially to overcome the problems of the slurry, sewage, mud and other harsh mining, as well as the easily plugged problems. This product also overcomes many shortcomings of the existing outlet valve. This product is In accordance with the trend of valve automation , energy-saving, environmental protection. 2.use Dome-type Gas Control Valve is installed in the oulet of power pump, slurry pump, sewage pump, mud pump, water pump, mainly used for electric power, metallurgy, mining petrochemical, chemical, pharmaceutical, wastewater, paper and other industries. It can not only eliminate water hammer, but also , with small resistance It is energy-saving, small, low cost, , which is applicable to slurry, sewage, mud, water and other systems
