Electric pneumatic control valve at the time of installation and use what?

Electric pneumatic control valve belongs to the pneumatic control valve, plays a very important role in industrial automation, is mainly to control its important execution unit instrument. Forehead with the industry more and more high degree of automation, is being more and more application in the field of all kinds of industrial production. Electric pneumatic control valve at the time of installation and use what? In use at the scene, many are often not because of quality caused by the pneumatic - valve itself, but rather that caused by improper use of pneumatic control valve installation, such as installation environment, installation position and direction due to reasons such as caused by improper or line is not clean. So electric pneumatic - valve during installation should pay attention to the following aspects: 1, pneumatic control valve belongs to the field instruments, require the environment temperature should be in 25 ~ 60 ℃, relative humidity 95% or less. If it is installed in the open air or high temperature applications, waterproof, cooling measures should be taken. Where there is the source to stay away from source or increase the antivibration measures. 2, pneumatic control valve before installation for pipeline cleaning, eliminate dirt and welding slag. After installation, to ensure that no residue in the body, should also again to the valve and clean, the access into the medium should make all open valve, in order to avoid impurity stuck. After using the handwheel institutions, should be restored to the original neutral position. 3, in order to make the pneumatic control valve in the event of a fault or repair can continue to make the production process, under the condition of pneumatic control valve should add by-pass line. At the same time also should pay special attention to, the installation of the pneumatic control valve position whether accord with the requirement of technological process. 4, actuator reducer lubrication, should be paid attention to after repairing and low speed motor generally don't cheer unpick and wash. After assembly also should check whether the valve position and the opening of the valve position indicator. 5, pneumatic control valve should be installed vertically, commonly special circumstances can tilt, such as the Angle is very big, or too much weight on the valve when the valve itself should increase support protection. 6, pneumatic control valve installation of pipe generally do not too high above the ground or floor, height is greater than 2 m in pipe should try to set up the platform, facilitate the handwheel operation and easy maintenance.
