Description

Technical Field

[0001] The utility model relates to the technical field of metering pumps, in particular to an adjusting rod locking structure for a metering pump. Background Art

[0002] A metering pump is a type of fluid conveying machinery. Its outstanding feature is that it can maintain a constant flow rate that is independent of the discharge pressure. The use of a metering pump can simultaneously complete the functions of conveying, metering and regulation. Metering pumps are widely used in various industrial fields such as petrochemicals, pharmaceuticals, and food. After implementing flow regulation, a locking structure is required to prevent the structure from loosening.

[0003] The prior art patent document with publication number CN215566418U discloses a hydraulic metering pump flow regulating device that is easy to adjust. The utility model sets an adjustment component, and the staff drives the adjustment rod to rotate by rotating the corresponding model of the plum blossom wrench. The adjustment rod can drive the seal to adjust the diameter of the connecting pipe connected to the pump body to adjust the real-time flow of the pump body. When the staff adjusts the flow of the pump body, the staff only needs to observe the scale indicated by the indicator arrow to understand the real-time flow of the pump body. The staff does not need to detect the real-time flow of the pump body after the adjustment is completed, which greatly reduces the probability of rework by the staff at a later stage, thereby reducing the difficulty of adjustment for the staff.

[0004] However, in the prior art CN215566418U patent, it is not convenient to lock the adjusting rod after adjusting the flow of the metering pump, which leads to delays in work progress, and has low practicality and functionality. Utility Model Content
