Description

Technical Field

[0001] This utility model relates to the field of gas pressure reducing valve manufacturing technology, and in particular to a valve cover assembly installation device and a valve assembly production line. Background Technology

[0002] In the production process of gas pressure reducing valves, installing the valve cover assembly (including the valve cover and spring) onto the valve base cup assembly (which contains the valve stem and diaphragm assembly) is the final and crucial step in the manufacturing process. (Refer to...) Figure 8 or Figure 9 The process of installing the valve cover assembly onto the valve bottom cup assembly is as follows: 1. Manually fitting one end of the spring element onto the diaphragm assembly located in the cup cavity of the valve bottom cup assembly; 2. Manually covering the cup cavity of the valve bottom cup assembly with the valve cover element, so that the other end of the spring element abuts against the valve cover element; 3. Manually using a riveting device to press the annular rim wall of the cup cavity of the valve bottom cup assembly against the valve cover element, thus sealing the cup cavity of the valve bottom cup assembly. As can be seen from the above, the process of installing the valve cover assembly onto the valve bottom cup assembly requires manual intervention. The problems with this process are: 1. High labor costs; 2. Directly using a riveting device to press the annular rim wall can easily cause deformation of the annular rim wall, affecting the sealing performance of the cup cavity.
