Analysis of electric pneumatic valve ball

electric pneumatic valve ball is mainly applicable to gas, oil, air and water and other medium, due to the advantage of electric pneumatic valve ball has a lot of, so it has a very wide range of use, the following will mainly introduce the advantages of electric pneumatic valve ball.
is mainly applicable to gas, oil, air and water and other medium, because of the advantage of electric pneumatic valve ball has a lot of, so it has a very wide range of use, the following will mainly introduce the advantages of electric pneumatic valve ball. Electric pneumatic valve ball mainly has the advantage of:
, in the earth pressure and temperature range, can achieve completely sealed;
and reliable working medium on the double seal;
, can bear stress from the pipe;
, which can realize the rapid opening and closing;
, ball close to automatically locate on location.
electric pneumatic valve ball there are plenty of advantages, so in the process of use, can make full use of the advantages of electric pneumatic valve ball, this equipment can fully use.
in order to reduce the pneumatic ball valve operating torque and increase the reliability of the sealing, pneumatic valve oil seal ball appeared again in recent years, both betting special lubricant between the sealing surface, in order to form a layer of oil film, which increases the sealing, and reduce operating torque, suitable for pneumatic ball valve with high pressure, large diameter.
electric pneumatic valve ball not only in oil and gas, chemical industry, water disposal industry widely applied, but also used in cooling water system of thermal power plants. Commonly used electric pneumatic valve has the wafer electric ball pneumatic valve and flange electric pneumatic valve two kinds. Wafer electric pneumatic valve is a ball in the stud bolt connect pneumatic valve in place between two pipe flanges and flanged electric pneumatic valve ball is pneumatic valves with flange, bolted flange connection on both ends on the pneumatic valves in pipeline flange. The strength of the pneumatic valve performance is refers to the pneumatic valve on medium pressure ability.
in the pressure pipeline, the liquid flow rate caused by the rapid changes in the phenomenon of pressure fluctuations significantly. In medium conveying, can cause water hammer phenomenon mainly pneumatic valve suddenly turned on or off, etc. Water hammer can cause a sharp shock of pipeline system, it will cause water pipes, severe water hammer, it's for water hammer effect. Pneumatic valve shut down suddenly, reached the maximum hydraulic quickly. Here is called water hammer. Pneumatic valve suddenly opened, also can produce water hammer, but not obvious, less harm. Electric slow kick-off pneumatic valve, pneumatic valve closing time on S - S between, closed at a constant speed, in this way, will effectively avoid water hammer.
