Embodiment 2

[0017] This is an embodiment that utilizes the combined application of the valve core and the ball valve, which gives full play to the good sealing performance of the ball valve, absorbs the advantages of the good adjustment performance of the valve core, and achieves complementarity. see Figure 8 , It is mainly composed of flow limiting device 1, and flow equalizing device 2, adjusting rose 3. The valve stem 4, the three-way valve ball 7 (also serving as the housing 5 of the valve core), and the flow port 6 of the valve. The valve body 8 is currently in the open state. The working process is that when we need to set the maximum flow limit of the equipment, by rotating the adjustment rose 3, the flow limiting device 1 is moved back and forth to block the flow port 6 of the valve. In order to achieve the purpose of limiting the maximum flow. When adjusting the flow, because in this embodiment, the middle hole of the three-way valve ball 7 is used to replace the valve core hou...

Abstract

A valve core being capable of adjusting, limiting and equalizing flow quantity is characterized by consisting of a limit device (1) of the flow quantity and an equalizing device (2) of the flow quantity. An adjusting screw is arranged on the limit device of the flow quantity. Due to the technical scheme, when the flow quantity of a selected valve is greater than flow quantity needed by a device, the limit device (1) of the flow quantity can be moved forward and backward by rotating the adjusting screw 3 and then enabled to shield a part of circulation holes. Furthermore, due to the fact that the equalizing device of the flow quantity is arranged, regardless of selected sizes of valves, effective adjusting angles of the valves can be fully adjusted by 90 degrees, and due to the valve core is in a linear output mode, so that purposes of adjusting, limiting and equalizing the flow quantity are achieved.

Description

Technical field [0001] The invention relates to the field of valves. Background technique [0002] Existing valves, such as ball valves, butterfly valves or plug valves, have the following shortcomings in actual use. First, the maximum flow rate of the valve is inconsistent with the maximum required flow rate of the equipment. Because the existing valves, caliber (flow) are all produced according to the standard, and the maximum required flow of the equipment using the valve is indeed very different, which makes the user choose a valve larger than the actual flow when selecting a valve. Those that are not allowed to oversupply are not suitable, especially those that are frequently operated. If you don’t pay attention, oversupply will happen, and it is easy to cause dangers and accidents. Therefore, in many equipment , We have to put in a restrictive valve in series to ensure that oversupply will not occur. This increases the cost, takes up space, and also increases the leakage r...
