Those things about electric swafer butterfly valves
With the development of electric valves, there are many well-known enterprises at 首页 and abroad, and now electric butterfly valves are more and more widely used in practical applications. It is an important execution unit in the field of industrial automation control. It belongs to a variety of electric valves and electric Control Valves. It is widely used in textile, power station, petrochemical, heating and refrigeration, pharmaceutical, shipbuilding, metallurgy, light industry, environmental protection and other fields. This product can be used as shut-off valve, Control Valve and check valve in piping system. Complete manual controls, electric or pneumatic transmissions, can meet the specific conditions of different working conditions. Meets the most stringent quality requirements for very long-lasting applications. Especially in the metallurgical steel and shipbuilding industries, it has a very high reputation.
Description of features:
1. The design is novel, reasonable, unique in structure, light in weight, and fast in opening and closing.
2. The operating torque is small, the operation is convenient, and the effort is savvy.
3. It can be installed in any position, and it is easy to maintain.
4. The seals can be replaced, and the sealing performance is reliable to achieve zero leakage of two-way sealing.
5. The sealing material is age-resistant, corrosion-resistant, and has a long service life.
The electric swafer butterfly valve is suitable for applications where flow regulation is required. Because the pressure loss of the butterfly valve in the pipeline is relatively large, about three times that of the gate valve, when selecting the butterfly valve, the influence of the pressure loss of the pipeline system should be fully considered, and the firmness of the butterfly plate to bear the pressure of the pipeline medium when it is closed should also be considered. In addition, the limitations of the operating temperature to which the elastomeric seat material can be subjected at high temperatures must also be taken into account. The structural length and overall height of the butterfly valve are small, the opening and closing speed is fast, and it has good fluid control characteristics, and the structural principle of the butterfly valve is most suitable for making large-diameter valves. When a butterfly valve is required to be used to control the flow rate, it is important to select the correct size and type of butterfly valve so that it can work properly and effectively. In general, in throttling, regulation control and slurry media, the midline butterfly valve requires a short structural length and a fast opening and closing speed (1/4 turn). Low pressure cut-off (small pressure difference), butterfly valve is recommended. Butterfly valves can be used when there is a small amount of leakage into the atmosphere and abrasive medium in the case of double-position adjustment, necked ground channel, low noise, cavitation and gasification, a small amount of leakage to the atmosphere, and abrasive medium. When the butterfly valve is used under special working conditions, such as throttling adjustment, or strict sealing, or severe wear, low temperature (cryogenic) and other working conditions, it is necessary to use a special butterfly valve with metal seal with adjustment device.
