Embodiment 1
[0029] The preparation method of the high-pressure switch tube valve of the present embodiment includes the following steps:
[0030] 1) Blank processing: blank the high-pressure switch pipe valve, the specific composition of the materials used is shown in Table 1, according to figure 1 The structure shown in the lathe is used to process the blank of the high-pressure switch tube valve.
[0031] The blank of the high-pressure switch pipe valve includes an intermediate pipe section and a closing section and an opening section respectively connected to both ends of the intermediate pipe section. The process allowance on the outer pipe wall of the closing section and the opening section is 0.3 mm. The process reserve of the outer pipe wall of the pipe section is not less than 2mm;

[0033]
[0034] 2) Carburizing: Carburize the high-voltage switch tube valve blank obtained in step 1) at 910° C. in a box-type carburizing furnace to form a carburized layer on ...
Embodiment 2
[0041] The preparation method of the high-pressure switch tube valve of the present embodiment includes the following steps:
[0042]1) Blank processing: The high-pressure switch tube valve is blanked. The specific composition of the materials used is shown in Table 1. The blank of the high-pressure switch tube valve is machined in the same manner as in Example 1. The blank of the high-pressure switch pipe valve includes an intermediate pipe section and a closing section and an opening section respectively connected to both ends of the intermediate pipe section. The process allowance on the outer pipe wall of the closing section and the opening section is 0.2mm. The process reserve of the outer pipe wall of the pipe section is not less than 2mm;
[0043] 2) Carburizing: Carburize the high-pressure switch tube valve blank obtained in step 1) at 930° C. in a well-type carburizing furnace to form a carburized layer on the surface of the high-voltage switch tube valve. The thickne...
