Jane about electric pneumatic control valve and pneumatic pneumatic control valve

Electric pneumatic control valve with pneumatic control valve of pneumatic and become two giants of pneumatic control valve, because of its easy to use, save a lot of manpower material resources characteristics and was deeply loved by the masses. In the industrial automation process control plays an important role, has been widely used in various industrial fields. But in use, will appear a lot of problems, this article will explain for everybody. Compared with traditional pneumatic pneumatic - valve has obvious advantages: energy saving (electric pneumatic regulator Only electricity when at work) , environmental protection, No carbon emissions) Fast installation, convenient, No need for complicated pneumatic pipe and pump stations) 。 Valve by their ticket enforcement agencies use the power, according to its functions and features are divided into linear features, such as percentage and parabolic characteristics of three. In the field use, a lot of electric pneumatic regulator problems often caused by the quality, not because of pneumatic control valve itself but the pneumatic control valve installation that caused by improper use, such as improper installation environment, installation position and direction or be caused by the reason such as the line is not clean. Electric pneumatic control valve and pneumatic pneumatic - valve using note (1) pneumatic - 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. Diction of 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. (3) the installation of pneumatic control valve 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. (4) 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. 5] 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. [6] electropneumatic valve electrical part of the installation shall be in accordance with the relevant requirements for electrical equipment construction. So flameproof products should be according to the explosive dangerous location electrical equipment installation specification requirements for installation. Such as the scene copper-clad SBH type or other six or eight core, outer diameter for? 吗? 11. About 3 mm rubber cable installation. In the use of maintenance, in the explosive place the flame-proof surface electricity open repair and shall be strictly forbidden to pry. At the same time in dismantling the harm upon or scratch flame-proof surface, after repair to be reverted to the original state of flame-proof requirement. Once 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.
