1. Haɗin flange
Haɗin da aka haɗa da flanges wani jiki ne na bawul mai flanges a ƙarshen biyu, wanda ya yi daidai da flanges ɗin da ke kan bututun, ta hanyar bolting flange ɗin da aka sanya a cikin bututun. Haɗin da aka haɗa da flanges shine nau'in haɗin bawul da aka fi amfani da shi. Flanges suna da convex (RF), plane (FF), convex da concave (MF) da sauran wurare. Dangane da siffar saman haɗin gwiwa, ana iya raba shi zuwa nau'ikan masu zuwa:
(1) nau'in santsi: don bawul ɗin da ke da ƙarancin matsi. Sarrafa shi ya fi dacewa;
(2) nau'in concave da convex: matsin lamba mai yawa, ana iya amfani da gasket mai tauri;
(3) Nau'in ramin tenon: gasket mai babban nakasar filastik za a iya amfani da shi sosai a cikin kafofin watsa labarai masu lalata, kuma tasirin rufewa ya fi kyau;
(4) nau'in ramin trapezoidal: zoben ƙarfe mai siffar oval a matsayin gasket, wanda ake amfani da shi a cikin matsin lamba na aiki na bawul ≥64 kg/cm2, ko bawul mai zafi mai yawa;
(5) Nau'in ruwan tabarau: gasket ɗin yana cikin siffar ruwan tabarau, wanda aka yi da ƙarfe. Ana amfani da shi don bawuloli masu matsin lamba mai ƙarfi waɗanda ke da matsin lamba ≥ 100kg/cm2, ko bawuloli masu zafin jiki mai yawa;
(6) Nau'in zoben O: wannan sabon nau'i ne na haɗin flange, yana tare da fitowar kowane nau'in zoben O-ring na roba, kuma an haɓaka shi, ya fi aminci a cikin tasirin rufewa fiye da gasket ɗin lebur na gabaɗaya.
(1) Haɗin walda da duwawu: ana sarrafa ƙarshen jikin bawul ɗin guda biyu zuwa ramin walda da duwawu bisa ga buƙatun walda da duwawu, wanda ya dace da ramin walda da bututu, kuma ana gyara shi a kan bututun ta hanyar walda.
(2) haɗin walda na soket: ana sarrafa ƙarshen jikin bawul ɗin biyu bisa ga buƙatun walda na soket kuma an haɗa su da bututun ta hanyar walda na soket.
Haɗin zare hanya ce mai dacewa ta haɗawa kuma galibi ana amfani da ita ga ƙananan bawuloli. Ana sarrafa jikin bawul ɗin bisa ga zaren da aka saba, kuma akwai nau'ikan zare na ciki guda biyu da zare na waje. Yana daidai da zaren da ke kan bututun. Haɗin zare ya kasu zuwa yanayi biyu:
(1) rufewa kai tsaye: zare na ciki da na waje suna taka rawa kai tsaye wajen rufewa. Domin tabbatar da cewa haɗin bai zube ba, sau da yawa tare da man gubar, hemp da PTFE bel ɗin cika kayan; Daga cikinsu, ana amfani da bel ɗin PTFE sosai. Wannan kayan yana da kyakkyawan juriya ga tsatsa, kyakkyawan tasirin rufewa, mai sauƙin amfani da shi da kuma adanawa, lokacin da aka wargaza shi, ana iya cire shi gaba ɗaya, saboda wani Layer ne na fim mara ƙamshi, ya fi man gubar kyau, hemp kyau.
(2) rufewa kai tsaye: ƙarfin matse sukurori yana yaɗuwa zuwa gasket ɗin da ke tsakanin jiragen biyu, don haka gasket ɗin yana taka rawar rufewa.
Akwai nau'ikan zare guda biyar da aka fi amfani da su:
(1) Tsarin ma'auni na gama gari;
(2) Zaren da aka saba da shi na inci;
(3) Zaren bututun rufe zare;
(4) zaren bututun rufewa mara zare;
(5) Zaren bututu na yau da kullun na Amurka.
