Flanged Ventilation Butterfly Valve

1. Introduction of Electric Flange Ventilation Butterfly Valve:

The electric flange type ventilation butterfly valve has compact structure, light weight, easy installation, small flow resistance, large flow rate, avoids the influence of high temperature expansion, and is easy to operate. At the same time, there are no connecting rods and bolts in the body, so the work is reliable and the service life is long. It can be installed in multiple positions without being affected by the flow direction of the medium. It is suitable for pipelines with a medium temperature of ≤300°C and a nominal pressure of 0.1Mpa in the production process of building materials, metallurgy, mining, and electric power, to connect, open and close or adjust the medium volume. Among them, the electric flange type ventilation butterfly valve can use suitable materials to meet the low, medium and high temperature of different media and corrosive media, which is unmatched by other parts of the valve.

The electric flange type ventilation butterfly valve is designed and manufactured with a new type of welded centerline disc plate and short structural steel plate. It has a compact structure, light weight, easy installation, small flow resistance, large flow rate, avoids the influence of high temperature expansion, and is easy to operate. There are no connecting rods, bolts, etc. in the body, and the work is reliable and the service life is long. It can be installed in multiple positions without being affected by the flow direction of the medium.

 

2. Application characteristics of electric flange type ventilation butterfly valve

The electric flange type ventilation butterfly valve is a non-closed butterfly valve, which is suitable for the pipelines with a medium temperature of ≤300°C and a nominal pressure of 0.1Mpa in the production process of building materials, metallurgy, mining, electric power, etc., to connect, open and close or adjust the medium. quality. The electric flange type ventilation butterfly valve is mainly used in dusty cold air or hot air pipelines of ventilation and environmental protection projects in industries such as gold, chemical industry, building materials, power stations, glass, etc., as a gas medium to adjust the flow rate or cut off the device. The electric flange type ventilation butterfly valve is designed and manufactured with a new structural form of centerline disc plate and short structural steel plate welded.

 

3. Five characteristics of the electric flange type ventilation butterfly valve

1. The electric flange type ventilation butterfly valve is designed and manufactured with a new structural form welded by centerline disc plate and short structural steel plate, which avoids the influence of high temperature expansion and is easy to operate.

2. There are no connecting rods, bolts, etc. inside, reliable operation and long service life. It can be installed in multiple positions without being affected by the flow direction of the medium.

3. Novel and reasonable design, unique structure, light weight, quick opening and closing.

4. The electric flange type ventilation butterfly valve has small operating torque, convenient operation, labor saving and dexterity.

 

4. How to increase the stability of the flange type ventilation butterfly valve

The flange type ventilation butterfly valve includes a base. The base of the product is equipped with a valve body. The butterfly plate is set in the valve body. The metal shell and the sealing ring are arranged on the annular step surface of the valve body. The flange type ventilation butterfly valve adopted in the technical proposal of the utility model has the beneficial effects of low cost and good sealing effect, and is suitable for ventilation.

The preferred technical solution is that the ring-shaped metal shell of the valve body adopts a structure in which the ribs on both sides are recessed in the middle to form an annular recessed area, and reinforcing ribs are evenly distributed along the annular recessed area, so that the sealing effect is better; in addition, the formed In the annular recessed area, reinforcing ribs are evenly distributed along the annular recessed area, which is more conducive to stabilizing the valve body and increasing the stability of the entire butterfly valve.
