ELECTRIC DAMPER VALVE
OVERVIEW
The damper butterfly valve is a non-sealed butterfly valve, which is mainly used to control the flow and pressure of the medium in the pipeline. It has the characteristics of simple structure, light weight and easy installation.
The damper butterfly valve is designed and manufactured with a new structure of welding the centerline butterfly plate and the short structural steel plate. It has a compact structure and light weight, which is easy to install. It has small flow resistance and large flow volume, can avoid the influence of high temperature expansion, and is easy to operate. There are no connecting rods, bolts, etc. in the damper butterfly valve. It works reliably and has a long service life. It can be installed in multiple stations and is not affected by the flow direction of the medium.
The damper butterfly valve is widely used in pipelines with a medium temperature of ≤300℃ and a nominal pressure of 0.1Mpa in the production process of building materials, metallurgy, mining, electricity, etc., to connect, open and close or adjust the flow of the medium. At the same time, the damper butterfly valve is also suitable for water, steam, oil, nitric acid, acetic acid, oxidizing media, urea and other media of different materials, and can be driven by manual, turbine drive, pneumatic or electric.
In addition, the valve body of the damper butterfly valve is usually made of high-strength cast iron material, which has good pressure resistance and corrosion resistance, and can adapt to various harsh working environments. The valve disc of the butterfly valve is made of stainless steel, which has good sealing performance and wear resistance, can ensure the reliable sealing of the medium and reduce the risk of leakage. The operation of the damper butterfly valve is flexible and reliable, and the valve can be switched and adjusted by manual and electric operation.
In general, the damper butterfly valve has the characteristics of simple structure, reliable performance and long service life, and is an ideal fluid control equipment.
The specific working principle diagram of the damper butterfly valve is usually shown as a disc-shaped butterfly plate rotating around its own axis in the valve body to achieve the purpose of opening and closing or adjusting the medium flow. Since the figure cannot be directly displayed here, its working principle can be understood based on the description.
The butterfly plate of the damper butterfly valve rotates in the valve body. When the butterfly plate rotates to a position perpendicular to the pipeline axis, the valve is in a closed state, and the medium flow is cut off; when the butterfly plate rotates to a position parallel to the pipeline axis, the valve is in a fully open state, and the medium can flow freely; and when the butterfly plate rotates to any angle between the two, the medium flow can be adjusted.
This working principle makes the damper butterfly valve have the advantages of simple structure, small size, light weight, and easy operation, and is widely used in pipeline systems in building materials, metallurgy, mining, power and other industries.

Purpose
The damper butterfly valve is a non-sealed butterfly valve, widely used in the production process of building materials, metallurgy, mining, electricity, etc., with medium temperature ≤300℃ and nominal pressure of 0.1Mpa pipeline, used to connect, open and close or adjust the medium flow.
INSTALLATION TIPS
1. The installation position, height, and inlet and outlet directions must meet the design requirements. Note that the direction of the medium flow should be consistent with the direction of the arrow marked on the valve body, and the connection should be firm and tight.
2. The appearance of the valve must be inspected before installation, and the nameplate of the valve should comply with the provisions of the current national standard "General Valve Marking" GB 12220. For valves with a working pressure greater than 1.0 MPa and a cut-off function on the main pipe, strength and tightness performance tests should be carried out before installation, and they can only be used after passing the test. During the strength test, the test pressure is 1.5 times the nominal pressure, and the duration is not less than 5 minutes. The valve housing and packing should be leak-free to be qualified. During the tightness test, the test pressure is 1.1 times the nominal pressure; the test duration meets the requirements of GB 50243.
