Electric ball valve construction brief, only by a few parts, materials consumption province; small size, light weight, installation of small size, drive torque is small, pressure regulating valve is simple, quick, only to quickly rotate 90 ° open and close; and also it has good flow control characteristics of efficacy and sealed closed, the large size, scope of application of low pressure, electric ball valve is the dominant situation. Electric valve in the full open position, the disc thickness is the only medium resistance when flowing through the body, so that occurred through the valve pressure drop is small, it has a better traffic control features. Electric ball valve with elastic metal seal and the seal of two seal types. Flexible sealed valves, seals can be mounted on the body or attached to the disc periphery. To metal sealed valves generally higher than the valve seal flexible, long life, but it is difficult to achieve a complete seal. Metal seal can adapt to high temperature, flexible seal is restricted by temperature has drawbacks. If the request for electric valve for flow control use, it is important to choose exactly the size and type of valve. In particular, the construction principle of electric valve suitable manufacturing large diameter valves. Electric ball valve, not only in oil, gas, chemical, water disposal and other general industries are generally used, but also used in the thermal power station cooling water system. Electric ball valves are used on the clip electric electric ball valve flanged ball valve and two. Electric ball valve on the folder is double-headed bolts to connect the valve between the two pipe flanges, flange-style electric valve with a flange on a valve, the valve on both ends of the bolts in the flange interface pipe flange. Strength properties of the valve is the valve can be sustained media pressure. Suffered internal pressure valve is a mechanical product, and therefore must have sufficient strength and rigidity to ensure the long-term use without breaking or deformation produced. Function: is an industrial automation process control pressure pipe components, commonly used in pipeline media remote and off (turn, cut medium) control. Features: The integrated structure to single-phase power supply AC220V and DC power 24VDC operation can be controlled. Small, lightweight, reliable, simple matching, flow capacity and so on. Operating Characteristics: Suitable for large pipe pressure, sealed switches and demanding process to cut off pipeline medium occasions and fluid control systems. Operating temperature: -20 °C to 150 °C (250 °C special seal). Working pressure: PN16, PN25 - PN40 - PN64-PN100 fluid range: air, steam, water, gas, oil and petrochemical products, corrosive media. Edit this paragraph structural features 1, the valve is fully open and fully closed position with lock hole to prevent the misuse of non-staff members. 2, set the stage in the lower stem, and will not abnormal increase in internal pressure valve prolapse valve stem. 3, in the sphere and set the fire-resistant seal between the valve seat ring, valve seat burning, still has the seal effect. 4, switch quickly, opening and closing a flexible, long life, safe and reliable. 5, pneumatic, electric valve can be remote centralized control, and can meet the needs of the computer program control.
