Intrinsically safe electric valve development has been designed to make it a throttle valve, and control intrinsically safe electric valve electric valve it has rotated 90 degrees to the action, cock body is spherical, with circular holes or channels through its axis. Valve in the pipeline is mainly used for electric valve cut distribution and change the direction of media flow, it only needs to operate with a rotating 90 degrees and a small torque can be closed tightly. Most suitable valve to make the switch, shut-off valve used, but recent development has been designed to make it a throttle valve and flow control purposes, such as V-ball. The main characteristics of the electric valve itself is compact, reliable sealing, simple structure, easy maintenance, regular spherical surface and seal in the closed state, the media can not easily be eroded, easy operation and maintenance for water, solvents, acids, and natural gas and other general working medium, but also for working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, etc., in various sectors has been widely used. Ball valve can be the whole, it can be modular. Electric valve structure is simple, by only a few parts, materials consumed Province; small size, light weight, small size, installation, drive torque, pressure regulating valve, simple, agile, simply rotate 90 ° to quickly start closed; and also also has a good flow regulation efficacy and closed sealing characteristics, in large and medium-caliber, low pressure areas of application, is the leading electric ball valve situation. Electric valve in full open position, the butterfly plate thickness is only when the medium flows through the valve body resistance through the valve pressure drop occurring is small, it has a better grip flow characteristics. Electric valve with elastic sealing two kinds of sealing and metal seal type. Elastic sealing valves, seals can be mounted on the body or attached to the disc periphery. Take the metal sealed valves generally higher than the elastic sealing valves, long life, but it is difficult to achieve a complete seal. Metal seal can accommodate the higher operating temperature, the elastic seal is a temperature limit of shortcomings. If the request is dominated electric valve used as a flow, it is important to choose exactly the size and type of valve. Electric valve construction principle is particularly suitable for manufacturing large diameter valves. Electric valve not only in oil, gas, chemical, water treatment and other general industries widely use, but also the use of the thermal power plant cooling water system.
