Description

Technical Field

[0001] This invention relates to the field of gas pressure reducing valve manufacturing technology, and in particular to a hose assembly installation device and a valve assembly production line. Background Art

[0002] In existing production processes, some manufacturers connect pre-assembled gas pressure reducing valves to hose assemblies (which include hose sections, two caps, a pagoda nut, and a pagoda connector) to obtain finished gas pressure reducing valves for user use after shipment. (Refer to...) Figure 8 or Figure 9 The process of connecting a gas pressure reducing valve to a hose assembly to obtain a finished gas pressure reducing valve is as follows: 1. Manually cut a hose section to a preset length; 2. Manually attach two caps to the two ends of the hose section; 3. Manually insert a pagoda connector into a pagoda nut, and then insert it into one end of the hose section, so that the pagoda nut is sandwiched between the pagoda connector and the corresponding cap; 4. Manually insert the gas outlet pipe of the gas pressure reducing valve into the other end of the hose section; 5. Manually use a hose shrinking device to shrink and tighten the two caps on both ends of the hose section. As can be seen from the above, the production process of the finished gas pressure reducing valve requires manual intervention, resulting in low production efficiency. Therefore, in order to improve the production efficiency of the finished gas pressure reducing valve, the inventor aims to solve the problem of designing a hose assembly installation device that can reduce manual intervention and connect the gas pressure reducing valve to the hose assembly.
