Grinding wheel quick control valve

3HH-MKT61YGrinding wheel quick control valveWorking principle

The MT series flow meter regulating valve for grinding wheel rapid control valve is a generation of flow regulating valve that our company has developed with reference to foreign technology and careful research Widely used in various fields such as petroleum, chemical, power, pharmaceuticals, etc., especially suitable for high-pressure water injection, steam injection, water mixing and other pipelines in oil fields, and used in conjunction with flow meters as flow control valve control devices.

MKT61YGrinding wheel quick control valvePlease refer to the following figure for the working principle. The medium fluid enters the valve chamber from the inlet end of the valve. Assuming that the valve is in the "closed" state, as shown in Figure (a), the throttle holes on the two grinding wheels are in a vertically opposite position, and the flow channel is blocked; Subsequently, when the handle begins to rotate at a certain acute angle and is transmitted through the connection of the valve stem, the dynamic grinding wheel also rotates at an acute angle. At this point, the relative position of the two grinding wheels forms the flow path shown in Figure (b). The flow channel on the working surface is two crescent shaped holes, and the fluid is divided into two branches through the two crescent shaped holes, which then merge into one flow and flow out from the outlet of the valve. MKT61YGrinding wheel quick control valveAdjusting the flow rate is achieved by rotating the handle at any angle between 90 degrees to change the flow area of the channel composed of two dynamic and static grinding wheels. The entire process of channel changes on the working surface is similar to the changes in the roundness of the celestial moon. When the handle continues to rotate to the "fully open" position, the channel is opened, and the cross-section of the channel on the working surface is like two full moon moons, as shown in Figure (c). Another explanation, MKT61YGrinding wheel quick control valveIn work, the fluid exerts a certain pressure on the grinding wheel, making the dynamic and static grinding wheels always tightly adhere to each other, further enhancing the sealing effect of the working surface. Even in reverse flow conditions, it also has good sealing performance.
