The Throttle Valve uses power to drive an electric actuator and then drive the valve to throttle. It is an important execution unit instrument in industrial automation process control. As the degree of automation in the industrial field becomes higher and higher, it is being increasingly used in various industrial production fields. The Throttle Valve has obvious advantages: the electric single-seat Universal Valve is energy-saving, environmentally friendly, and the installation is faster and more convenient.
The Throttle Valve receives signals from the industrial automation control system to drive the differential pressure Universal Valve series door to change the cross-sectional area between the valve core and the valve seat to control the flow, temperature, pressure and other process parameters of the pipeline medium to achieve automated adjustment functions.
The electric actuator of the electric sleeve Universal Valve is an electronic integrated structure with a servo amplifier inside. In order to ensure that the Universal Valve can work normally when driving and make the system operate safely, before installing a new valve, you should first check the valve Whether the nameplate markings comply with the design requirements.
If the Universal Valve in the original system is overhauled, in addition to checking the above items, the sealing of the stuffing box and connections of the old valve should also be checked.
When the Universal Valve is used on site, many problems are often caused not by the quality of the Universal Valve itself, but by improper installation and use of the Throttle Valve, such as: improper installation environment, improper installation position and direction, or unclean pipelines, etc. To.
1. The Throttle Valve is an on-site instrument and requires that the ambient temperature should be in the range of -25~60℃ and the relative humidity should be 95%. If it is installed in the open air or in a high-temperature place, waterproofing and cooling measures should be taken. In places where there are earthquake sources, stay away from the source of vibration or add anti-vibration measures.
2. The Throttle Valve should generally be installed vertically. It can be tilted under special circumstances. For example, if the tilt angle is large or the valve itself is too heavy, supporting parts should be added to protect the valve.
3. The pipeline where the Throttle Valve is installed should generally not be too high from the ground or floor. When the pipeline height is greater than 2m, a platform should be set up as much as possible to facilitate the operation of the handwheel and facilitate maintenance.
4. Before installing the Throttle Valve, the pipeline should be cleaned to remove dirt and welding slag. After installation, in order to ensure that no impurities remain in the valve body, the valves 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 be restored to its original neutral position.
