Problems solved by technology

[0002] At present, butterfly valves are widely used in chemical engineering, water conservancy, fire protection, engineering and other pipeline machinery fields due to their advantages of convenient control, safety, wear resistance, and engineering; with the rapid development and renewal of various fields, existing butterfly valves The processing and manufacturing of butterfly valves can no longer meet the demand; traditional butterfly valve manufacturers, when producing and assembling the rubber sleeves of butterfly valves, are basically assembled by hand, that is, the rubber sleeves and butterfly plates are manually driven into the valve with a hammer. In vivo, there are the following shortcomings: different processes require different people to assemble, and the technical requirements are high; time-consuming, it takes more than 10 minutes from the first step to the last step; laborious, from the first step to the last step , the labor intensity is relatively high; due to the requirements of processing standards, it is easy to be biased during the assembly process, damage, bias and other losses, often reworked many times to meet the standard; the efficiency is low

[0003] Therefore, there are many advanced technologies and professionals in this field, who have continuously improved and adjusted the butterfly valve assembly machinery for a long time to meet the needs of development; however, the existing butterfly plate assembly machinery for butterfly valves is already very advanced, but the operation It is not convenient enough, and the main control hydraulic pressure cannot be adjusted and controlled in time according to the model and specification according to the processing standard. Once a failure occurs, the repair and maintenance cost will be increased, and the work efficiency will be reduced; When the plates are assembled and assembled, the safety factor of the main machine of the existing butterfly valve assembly machine is low, resulting in deformation of the butterfly plates of different specifications and models when assembled and pressed by the existing butterfly valve assembly machine, which affects the quality of the butterfly valve; Then, when assembling the butterfly discs of the butterfly valve, the finished product rate of the processed butterfly valve needs to be further improved to reduce the consumption of additional energy resources; for a long time, it has been the bottleneck in the development of this field, affecting the development of butterfly valve assembly machinery, and it is difficult to meet the needs of the market and user needs
