Description

Technical Field

[0001] The utility model relates to the technical field of gas pressure reducing valve production, in particular to a moving mechanism and valve stem assembly installation equipment. Background Art

[0002] A gas pressure reducing valve includes a valve bottom cup assembly and a valve stem assembly rotatably connected to the inner cavity of the valve bottom cup assembly, wherein the valve stem assembly can close the inner cavity of the valve bottom cup assembly and the air inlet of its air inlet pipe to cut off the gas from entering the inner cavity of the valve bottom cup assembly.

[0003] When the valve stem assembly is rotated and installed in the inner cavity of the valve bottom cup assembly, refer to Figure 7 and Figure 8 The valve stem assembly needs to be flipped before the two ends of the rotating shaft can be inserted into the two rotating grooves of the inner cavity of the valve bottom cup assembly one by one. Since the flipping and inserting action of the above-mentioned valve stem assembly is relatively complicated, most of the existing installation equipment is realized by two mechanisms (one mechanism flips the valve stem assembly and places it on the jig, and the other mechanism moves the flipped valve stem assembly on the jig and inserts it into the inner cavity of the valve bottom cup assembly). However, the settings of the above-mentioned two mechanisms have the following problems: 1. The space occupied by the two mechanisms is relatively large; 2. The cost required for the setting of the two mechanisms is relatively high. Utility Model Content
