[0001] The utility model relates to the technical field of diaphragm pumps, in particular to a diaphragm pump connecting device. Background Art

[0002] The diaphragm pump is a pump equipment that can transport various media and is widely used in the fields of metallurgy and chemical industry. The hydraulic end of the diaphragm pump has three cavities and cylinders, three diaphragm chambers, three feed valve boxes, and three feed valve boxes. Among them, the connection between the feed port of the diaphragm chamber and the feed valve box is mainly composed of a 90° elbow and a short pipe.

[0003] During use, 90° elbows and short-circuit connection flanges often leak, causing the production system to stop, which has a great impact on production. The energy consumption during the start-up and shutdown process is high, which increases production costs. However, if the system is not stopped for processing, it will cause serious pollution to the production site and bring greater safety risks. The existing connecting pipeline is designed and cast by first measuring the distance between the feed port and the feed valve box, and then designing and casting the pipeline. This method is time-consuming, and when using different diaphragm pumps, they need to be redesigned and cast because of different sizes. Utility Model Content
