Description

Technical Field

[0001] The utility model relates to the technical field of flow switches, and more specifically, to an upper cover structure for a flow switch. Background Art

[0002] Flow switches are mainly installed online or plug-in in water, gas, oil and other medium pipelines to monitor the water flow in the water system. When the water flow is higher or lower than a certain set point, the output alarm signal is triggered and transmitted to the unit. After receiving the signal, the system can make corresponding indication actions, which is mainly used to avoid or reduce the "dry burning" of the host.

[0003] Most of the existing flow switches are fixed to the pipeline by threaded rotation. The other end of the flow switch is provided with a wire of a reed switch, and the wire is connected to the water pump body. When disassembling the flow switch, since the wire end is fixed to the water pump body, the user must rotate the wire while rotating the flow switch, which requires the user to overcome the shape of the wire and apply force to the flow switch, which is very inconvenient. Similarly, the wire must be rotated for installation when reinstalling it, and when the wire is in a tangled state for a long time, the wire is prone to breakage, making the flow switch unusable, and the service life of the flow switch is greatly shortened.

[0004] In order to solve the above problems, the utility model patent with publication number CN211879300U discloses a new flow switch. The utility model adopts a split setting, including a fixed base and an upper cover body. The upper cover body is covered and fixed to the fixed base through a connecting piece, which solves the problem of the original integrated setting of the flow switch. When disassembling and installing the flow switch, it is necessary to overcome the shape of the wire and rotate the flow switch for installation. Compared with the previous method, it is more labor-saving and convenient. Moreover, the wires of the flow switch with this structure will not be damaged due to long-term entanglement of the wires, thereby increasing the overall service life of the flow switch.

[0005] However, when the flow switch is actually used, when the flow rate of the device in the water pump is detected, the water pump will vibrate during operation, causing the connection between the upper cover and the flow switch body to become loose, affecting the safety of the flow switch.
