Abstract

The invention belongs to the technical field of fluid control, and provides a device for flow direction switchover and flow control. The device comprises a valve element, a four-port valve seat, an end cover and a top cover. The valve element is composed of an outer ring, partition plates, a valve element bottom plate and a valve element shaft. The four-port valve seat is composed of a hole opening outer ring, necking components, a valve seat bottom plate and a sealing piece. The device has the following beneficial effects that firstly, flow direction switchover and flow control are achieved through a single valve, and a system is greatly simplified; secondly, a manner of diversion rather than throttling is adopted, the flow noise is controlled through the hole opening size, and noise is low; and thirdly, the device can generate constant flow resistance through the valve element hole opening arrangement, the flow resistance is equal under different work conditions and at valve rotation angles, a pump can work near a rated point, and running under a deviation work condition does not exist.

Description

technical field [0001] The invention belongs to the technical field of fluid control, and in particular relates to a device that can be used for flow direction switching and flow control. Background technique [0002] Flow direction switching and flow control are two important functions in the fluid control system. Generally, flow direction switching is realized by multiple on-off valves on the pipeline, and flow control is realized by regulating valves. [0003] figure 1 Shown in is the traditional flow direction switching and flow control system. When supplying water from point A to point B, it is necessary to open the third on-off valve 3 and the first on-off valve 1, close the second on-off valve 2 and the fourth on-off valve 4, and adjust Valve 5 controls the flow; when water is supplied from point B to point A, the flow direction shown in the figure requires opening the second on-off valve 2 and the fourth on-off valve 4, closing the third on-off valve 3 and the first...
