What are the uses and characteristics of electric ventilation butterfly valves?

Electric universal butterfly valve is used for ventilation in chemical industry, building materials, power station, glass and other industries, as well as dusty cold air or hot air gas pipelines in environmental protection projects. As a pipeline control device to adjust or cut off the gas flow, this valve is generally used for horizontal installation in the pipeline. Butterfly valve is a control valve with simple structure, and it is also used for switching control of low-pressure pipeline medium. Weidun VTON ventilation butterfly valve is a kind of unsealed butterfly valve, unlike ordinary imported electric butterfly valves, which require sealing and zero leakage. Mainly divided into: ventilation.

Second, the structural characteristics of electric ventilation butterfly valve:

1, designed and manufactured with a new structural form of welding a mid-line dish plate and a short structural plate. The Wheaton VTON electric ventilation butterfly valve is compact in structure, light in weight, convenient to install, small in flow resistance, large in circulation and convenient to operate.

2. There are no connecting rods: bolts, etc. Reliable operation, can be installed in multiple stations, not affected by the flow direction of the medium.

Third, the electric ventilation butterfly uses:

Weidun VTON electric ventilation butterfly valve is a kind of unsealed butterfly valve, which is widely used in building materials, metallurgy, mining, electric power and other production processes. Medium temperature < 150 degrees. It is used for connection, opening and closing or adjustment on the pipeline with nominal pressure of 0. 1mpa.

Four, electric ventilation butterfly working principle:

There are two kinds of ventilation butterfly valves: manual transmission and electric transmission. The actuator can be driven by motor or turbine, so that the butterfly plate can rotate freely within 90 degrees to achieve the purpose of opening and closing or adjusting the medium flow.

Five, electric ventilation butterfly valve installation points:

1. The installation position, height and import and export direction must meet the design requirements. Pay attention to the flow direction of the medium and the direction of the arrow marked on the valve body, and the connection should be firm and tight.

2. The valve must be visually inspected before installation.
