Water treatment commonly used electric pneumatic valve and pneumatic pneumatic valve principle and their respective advantages

Actually many enterprises in our country about sewage treatment engineering of water treatment and environmental protection equipment is not very understanding, environment pollution is so serious now, many HuanBaoJie colleagues in the efforts for our environmental protection career and work on sustainable development, the following is the basic knowledge of the environmental protection water treatment give us a brief throughout, the following resolution to us in the workshop in the process of the produce of the piping, electric pneumatic valve and pneumatic principle and advantages of pneumatic valve.





electropneumatic valve usually consists of electric actuators, and pneumatic valves. Electropneumatic valve using electricity as power to pass pneumatic valves, electric actuators to drive the implementation of pneumatic valve switch. Medium switch of the pipes and then to achieve. Electropneumatic valve actuation moment than ordinary pneumatic valves, electric pneumatic valve switching speed can be adjusted, brief structure, protection, and can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium such as various types of fluid activities.


pneumatic pneumatic valve driven by pneumatic valve is with compressed air. Using compressed air driven actuators in combination of multiple sets of pneumatic piston movement and force to beam and the characteristics of the curve track, drive tubular spindle rotation, compressed air disks to each cylinder, changes in and out of the air position to change the spindle rotation direction, on the basis of load ( Pneumatic valve) The requirements of rotary torque required, can adjust the cylinder number combination, driving load ( Pneumatic valve) Homework. Pneumatic pneumatic valve can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium such as various types of fluid activities.





electropneumatic valve with pneumatic pneumatic valve their advantages:


1:, pneumatic pneumatic valve of gas medium and small diameter liquid effect is good, low capital, protection and convenient. Defect: the empty air pressure fluctuation, the influence of winter in the north are susceptible to empty air water influence, caused the transmission part frozen, not action. Are generally faster than electric pneumatic, electric flashlight dual-use. And pneumatic hand, gas and the price is quite high.


2, electropneumatic valve for liquid medium and large diameter gas effect is good, is not affected by climate. Is not affected by air compressed air pressure. Defect: high capital, owe good in damp environment.


3, slow electric pneumatic valve, electric pneumatic valve can achieve explosion-proof brand isn't a lot; Pneumatic pneumatic valve action quickly, explosion-proof relatively than the electric bottom ( Match what the attachment to see whether the pneumatic pneumatic valve, with big brand attachment will be more expensive than ordinary electric pneumatic valve) 。


4, electric pneumatic valve used in some large pipe diameter, because it is difficult to do but electropneumatic valve pneumatic stability than the pneumatic, switching speed slow, executing agency work card tooth phenomenon is seen for a long time. Pneumatic pneumatic valve switch speed, high accuracy, but requires stable air supply.
