The electric gas gate valve is suitable for medium: blast furnace gas, coke oven gas, producer gas, water gas, oil gas and other sewage gas, as well as liquefied gas, natural gas, mine gas and other clean gas. It is mainly used in gas production and city gas transmission and distribution pipelines in coal gasification, metallurgy and coking industries.
The transmission thread of the dark rod gate valve is located inside the body. During the opening and closing process, the valve stem only rotates, and the gate plate rises and falls in the valve body. Therefore, the height of the valve is small. The dark rod gate valve is usually equipped with an opening and closing position indicator above the valve cover to be suitable for environments with small space such as ships and trenches and large dust content.
What are the characteristics of electric gas gate valves?
Because the gas gate valve is a wedge type double gate valve, the processing precision of the wedge angle of the sealing surface is low, and it is easy to seal. The temperature change is not easy to cause the housing and the scratch, so the sealing surface is easy to repair after wear, but the structure is more complicated and the parts are more complicated. Many, the valve body and weight are large.
The gas gate valve is installed in the sewage gas and clean gas pipelines as closed circuit equipment, and is mainly used for the opening and closing control of gas pipelines of metallurgical, coking, gas, chemical and other enterprises.
