Introduction of electric ventilation butterfly valve

Before reading this article again, let's quote a sentence from Weidun VTON butterfly valve engineer: The electric ventilation butterfly valve is an unsealed butterfly valve with a pressure of 0. 1Mpa and dust and debris;

Specifically, we analyze the difference between ventilation butterfly valve and ordinary butterfly valve from its concept, structural characteristics, purpose, principle and installation instructions.

Introduction of electric ventilation butterfly valve:

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

Second, the structural characteristics of electric ventilation butterfly valve:

1, designed and manufactured with a new structural form of welding the mid-line dish plate and the short structural plate, with compact structure, light weight, convenient installation, small flow resistance, large circulation and convenient operation.

2. There are no connecting rods: bolts, etc. Therefore, it works reliably, can be installed in multiple stations, and is not affected by the flow direction of the medium. ?

Third, the electric ventilation butterfly uses:

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:

Weidun VTON ventilation butterfly valve can be divided into manual transmission and electric transmission, which can be driven by motor or turbine to make the butterfly plate rotate freely within 90 degrees, so as to achieve the purpose of opening and closing or adjusting 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. Before installing Weidun VTON electric ventilation butterfly valve, visual inspection must be carried out.
