Description

Technical Field

[0001] The utility model relates to the technical field of control valves, in particular to a four-in-one multifunctional control valve. Background Art

[0002] At present, the control valves in pipeline valves can already achieve multiple combined functions such as check valve, water hammer prevention, flow regulation and hydraulic balance, that is, one valve can replace the check valve and the balancing valve at the same time, which greatly facilitates user use. In addition, the number of valves installed on the pipeline is reduced, which also reduces the occurrence of leakage points.

[0003] Publication No. CN211779204U discloses an elbow-type multifunctional control valve. The patent sets the inlet and outlet ends of the valve body and valve cover perpendicular to each other according to the axis of the waterway. In this way, when the medium flows into the inlet end, it can bend 90° to change the flow direction and flow out from the outlet end, thus avoiding the trouble and inconvenience of adding a 90° right-angle elbow to the traditional pipeline. At the same time, this control valve can also achieve multiple combined functions such as check, water hammer prevention, flow regulation and hydraulic balance. One valve has multiple uses, which brings great convenience to users' installation and use. However, the patent still has the following problems in actual use:

[0004] By arranging the inlet and outlet ends of the valve body and the valve cover perpendicular to each other according to the axis of the waterway, when the medium flows into the inlet end, it can bend 90 degrees to change the flow direction and flow out from the outlet end, thus avoiding the trouble and inconvenience of having to add a 90 degree right-angle elbow to the traditional pipeline. However, in actual use, the connection between the valve disc and the valve stem is mainly fixed by bolts. When the valve disc is frequently opened and closed, the wear of the valve disc will increase. If the valve disc cannot be replaced in time, it will affect the use effect of the valve. It is inconvenient to fix and disassemble the valve disc by bolts, and the valve disc cannot be installed quickly and conveniently.

[0005] A four-in-one multifunctional control valve is proposed to solve the above problems. Utility Model Content
