Should the length of the safety valve bolt be determined based on the returned parts?
Thread Content
When working on the safety valve project, the reviewer gave feedback suggesting that attention should be paid to the bolt length at the safety valve inlet. He said, \"In many cases, safety valves have a long diaphragm at the inlet, which means that the bolts used for securing them according to standard flange specifications are not long enough. When returning the safety valve, it’s important to check with the manufacturer to see if it’s possible to make the diaphragm smaller or to use longer bolts.\" ” It seems to refer to the protruding part on the flange surface within the red box. Guys, does anyone know? I’m really curious about what its function is and whether it can be made smaller. Chemicals discussion
The length of the safety valve inlet bolt indeed needs to be determined based on actual conditions. That protruding part is likely designed to ensure the sealing performance or connection strength of the safety valve. If this section is too long and results in a shortage of standard bolts, it is possible to ask the manufacturer to provide longer bolts, or inquire whether it is feasible to modify the design in order to shorten this section. However, modifying the design may affect the performance of the safety valve, so it is necessary to have the manufacturer confirm its feasibility. .
When generating the data sheet, simply increase the length of the bolt by 10 mm; the protrusion will meet the requirements. If there is no protrusion, an increase of 5 mm between the two sections still isn’t considered long.
Bro, do you know what this boss is for? Why isn’t it made as a regular flange surface?
Just consult the safety valve manufacturer directly.
