Angle control valve structure and the use of precautions

Angle control valve structure and use of precautions:

In the process of automatic adjustment of production process, the control valve is an important and indispensable part, which is called the "hands and feet" of the production process automation and is one of the terminal control elements of the automatic control system. It is composed of two parts of the implementing agencies and the valve. From the hydraulic point of view, the control valve is a local resistance can vary the throttle element, the control valve is in accordance with the input signal by changing the stroke to change the drag coefficient, so as to achieve the purpose of regulating the flow.

1, Angle control valve structure: Angle control valve in addition to the angle of the valve body, the other structures are similar to the single seat valve, its characteristics determine its flow path is simple, small resistance, especially conducive to high pressure drop, high Viscosity, containing suspended solids and particulate matter fluid regulation. It can prevent coking, sticking and clogging phenomenon, but also easy to clean and self-purification.

2, angle control valve to use Note:

(1) Comparison of positive and negative use: Under normal circumstances, the angle type regulating valve adopts positive installation, that is, the bottoming in and out. Only in the case of high pressure and high viscosity, easy to coke, with suspended particulate matter case, it is recommended reverse installation, the material side into the bottom. The purpose of the reverse angle control valve is to improve unbalance force and reduce the wear on the valve core, but also conducive to high viscosity, coking and suspended particulate matter containing the flow, to avoid coking and plugging.
