Ama-valve ngokuvamile axhunywa kumapayipi ngezindlela ezihlukahlukene njengezintambo, ama-flange, ama-welding, ama-clamp, nama-ferrules. Ngakho-ke, ekukhetheni ukusetshenziswa, ungakhetha kanjani?
Yiziphi izindlela zokuxhuma zama-valve namapayipi?
1. Uxhumano olunemicu: Ukuxhuma okunentambo kuyisimo lapho iziphetho ezimbili zevalvu zicutshungulwa zibe imicu yangaphakathi noma imicu yangaphandle ukuze ixhumeke nepayipi. Ngokuvamile, ama-valve ebhola angaphansi kwama-intshi angu-4 nama-valve embulunga, amavalvu esango kanye nama-valve okuhlola angaphansi kwama-intshi angu-2 axhunywe kakhulu. Isakhiwo sokuxhuma esinentambo silula, isisindo silula, futhi ukufakwa nokuhlakazeka kulula kakhulu ukugcinwa nokushintshwa. Njengoba i-valve izokhula ngaphansi kwethonya lokushisa elizungezile kanye nokushisa okuphakathi ngesikhathi sokusetshenziswa, ukuze kuqinisekiswe ukusebenza kahle kokuvala uphawu, ama-coefficients wokunweba wezinto ezimbili ekugcineni kokuxhumana kufanele acatshangelwe ngokugcwele. Kungase kube namashaneli amakhulu avuzayo ekuxhumekeni kwentambo, ngakho-ke ama-sealant, amateyipu okuvala noma izigcwalisi zingasetshenziswa ukuvimba lezi ziteshi ukuze kwandiswe ukusebenza kokuvala. Uma inqubo kanye nempahla yomzimba we-valve ingashiselwa, ingaphinda ivalwe ngemva kokuxhumeka kwentambo. Ucansi lungaba ngcono.
2. Ukuxhumeka kwe-Flange: Ukuxhumeka kwe-Flange kuyindlela yokuxhumana evame kakhulu kuma-valve. Ukufakwa nokuhlakazeka kulula kakhulu, futhi uxhumano lwe-flange lunokwethenjelwa ekufakweni uphawu, okuvame kakhulu kuma-valve aphezulu kanye nobubanzi obukhulu. Nokho, ukuphela kwe-flange kusinda, futhi izindleko ziphakeme kakhulu. Ngaphezu kwalokho, lapho izinga lokushisa lidlula ama-350 ℃, ngenxa yokuphumula okukhasa kwamabhawodi, ama-gaskets nama-flanges, umthwalo wamabhawodi uzoncishiswa kakhulu, futhi ukuxhumana kwe-flange nokucindezeleka okukhulu kungase kuvuze, okungafaneleki ukusetshenziswa.
3. Izixhumanisi ezishiselwe Ukuxhumana okushiselwe ngokuvamile kunezinhlobo ezimbili zezakhiwo: i-socket welding kanye ne-butt welding. Ngokuvamile, i-socket welding isetshenziselwa ama-valve anengcindezi ephansi. Isakhiwo se-welding se-socket welding valves silula ukucubungula futhi kulula ukuyifaka. I-butt welding isetshenziselwa i-valve enengcindezi ephezulu inezindleko eziphezulu, futhi i-welding idinga ukugotshwa ngokwezinga lepayipi, okunzima ukulicubungula, kanye nenqubo yokushisela nokufaka nayo iyinkimbinkimbi kakhulu. Kwezinye izinqubo, ukuhlolwa kwe-radiographic okungabhubhisi nakho kuyadingeka ekushiseleleni koxhumano. Lapho izinga lokushisa lidlula i-350 ° C, umthwalo wamabhawodi uzoncishiswa kakhulu ngenxa yokuphumula kokukhasa kwamabhawodi, ama-gaskets nama-flanges, futhi ukuvuza kungase kwenzeke ekuxhumekeni kwe-flange ngokucindezeleka okukhulu.
4. Ukuxhunywa kwe-clamp Isakhiwo sokuxhuma i-clamp sifana ne-flange, kodwa isakhiwo saso silula futhi izindleko eziphansi zivame ukusetshenziswa emipayipi yenhlanzeko namadivayisi. Amapayipi e-sanitary adinga ukuhlanzwa, futhi kwenqatshelwe ngokuphelele ukuba nezinsalela zokukhiqiza amagciwane, ngakho-ke ukuxhunywa kwe-flange nokuxhunywa kwentambo akufanelekile, futhi ukuxhumeka kwe-welding kunzima ukukufaka nokuhlakazwa. Ngakho-ke, ukuxhunywa kwe-clamp yikhona okuvame kakhulu kumapayipi aluhlaza. indlela yokuxhumana.
