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 butterfly valves, basically assemble them by hand, that is, manually assemble rubber sleeves, assembly shaft sleeves, butterfly plates, valve stems, etc. The hammer is driven into the valve body, which has the following disadvantages: 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 It is very laborious and labor-intensive until the last step of the process; due to the requirements of processing standards, it is easy to be biased, damaged, and deformed during the assembly process, and it is often reworked many times to meet the standard; the efficiency is low

However, the existing butterfly valve assembly machinery is already very advanced, but the process is cumbersome and the operation is not convenient enough. The hydraulic pressure cannot be adjusted and controlled in time according to the model and specification according to the processing standards. Improve work efficiency; due to the huge power of the existing butterfly valve assembly and processing machinery, when assembling and pressing butterfly valves of different types and specifications, the safety factor of the existing butterfly valve assembly machine is not high, and then when assembling butterfly valves, the yield rate It needs to be further improved to reduce the consumption of additional energy resources, so the existing butterfly valve assembly machine is not easy to promote; for a long time, it has been the bottleneck in the development of this field, affecting the further development of butterfly valve assembly machinery, and it is difficult to satisfy the market and users. need to be improved urgently
