Preliminar y design t est gas key sex t oling str uct ur e f olowing f igur e by shows Qian cover 2, and sealed par ts 1 3, and sealed cir cle 1 sealed cir cle 2 5, and sealed part s 2 as Shang f igure by shows: ear ly set down of gas key sex t oling f or Shang figur e by shows, sealed parts 1 and 2 t hrough t hread conect ion, can demolit ion, sealed par ts 1 and Qian cover contact place has sealed cir cle, prevent gas leak, a, direction t hat f or gas enter ed dir ection. The str uctur e has m any f laws t o be improved include t he f olowing: seal par t f or t ubular, clamp, scr ewed toget her . Dir ections f rom a gas, by what means and pipe conect ions. I mproved methods, tube shaped par ts dif ficult o clamp and t ight en, you can change it s shape, hexagonal or ect angular, and the import ation of gas hoses can be used, so sealing par ts 2A direction can make a t hread and hose connections, wil ensur e t he gas input , and depending on t he inspect ion r equir ements, sealing part s 2 and hose connection f or a long tim e, so t hat you can use wit h bat ch inspection. I mproved sealing part s 1 and 2 as shown in t he figure are as folows: 5. 2. 2 air t ight tooling design str ucture design and calculat ion of t he m ost size, are calculat ed according to size. Sealing diameter of parts 1 26mm according t o t he t op diameter of 20mm it . Total widt h 136mm can m eet the nat ional st andard in t he hexagon of hexagons f ixtur e clamping requir ement s. Seal part s 55mm weld can m eet the lengt h requir ement . Thickness of 7mm and 18m m were acquired under t he par ts aft er welding height, can meet t he r equir ements covered par ts. Seal par t 1 int ernal dim ensions 94mm and 122mm according t o t he diamet er of t he welding part s, and meets the test r equir ements. M 125 is countr ies need an inner t hread diameter. To sum up, sealing part s 1 size design for which sour ces ar e available, in line wit h t he mechanical design r equir ement s, but also f acilt at e t he m anufacturing process of t he part s, in line wit h t he economic, easy processing char act er ist ics, material selection of Dur al
