Hydraulic Ball Valve Factory Introduces The Installation Detail
-
In field use, many are often not caused by the quality of the control valve itself, but caused by improper installation and use of the control valve, such as improper installation environment, installation location and direction, or unclean pipelines. Therefore, Hydraulic Ball Valve Factory introduces the following aspects when installing and using electric regulating valves:
1. The control valve is a field instrument, and the ambient temperature is required to be in the range of -25 to 60 °C, and the relative humidity is less than or equal to 95%. If it is installed in the open air or in high temperature places, waterproof and cooling measures should be taken. Where there is a vibration source, keep away from the vibration source or increase anti-vibration measures.
2. The regulating valve should be installed vertically in general, and can be tilted under special circumstances. For example, when the tilt angle is large or the valve itself is too heavy, the valve should be protected by a support.
3. Generally, the pipeline for installing the regulating valve should not be too high from the ground or the floor. When the pipeline height is greater than 2m, a platform should be set up to facilitate the operation of the handwheel and facilitate maintenance.
4. Before installing the regulating valve, the pipeline should be cleaned to remove dirt and welding slag. After installation, in order to ensure that impurities do not remain in the valve body, the valve should be cleaned again, that is, all valves should be opened when the medium is introduced to prevent impurities from getting stuck. After using the handwheel mechanism, it should return to the original neutral position.
5. In order to enable the production process to continue in the event of failure or maintenance of the regulating valve, the regulating valve should be equipped with a bypass pipeline. At the same time, special attention should be paid to whether the installation position of the regulating valve meets the requirements of the process.
6. The installation of the electrical part of the electric regulating valve should be carried out according to the construction requirements of the relevant electrical equipment.
7. After the reducer of the actuator is dismantled and repaired, attention should be paid to oiling and lubrication. Generally, the low-speed motor should not be disassembled, washed and refueled. After assembly, it should also be checked whether the valve position is consistent with the valve position opening indication.
