I-ANSI ASME B16.9 Indololwane Eshiselwe Insimbi Engagqwali Engenamthungo 45 Degree

Isethulo somkhiqizo

Kuhlelo lwamapayipi, iindololwanekuyinto efanelekile eshintsha indlela yokugijima. Uhlobo lokufakwa kwepayipi elixhumayo elivame ukusetshenziswa ekufakweni kwamapayipi, ukuxhuma amapayipi amabili anobubanzi obufanayo noma ahlukene obujwayelekile ukuze kwenziwe ipayipi lijike nge-engeli ethile, futhi ukucindezela okulinganiselwe kungu-1-1.6Mpa.

Ama-engeli ajwayelekile angama-45 ° no-90 ° 180 °. Ngaphezu kwalokho, kukhona ama-engeli angu-60 kanye nezinye izindololwane ze-engeli ezingajwayelekile ezidingwa iphrojekthi.

Izinto zama-elbows zifaka i-cast iron,insimbi engagqwali, insimbi eyingxubevange, insimbi esakhiwe ethambile, insimbi ye-carbon, izinsimbi ezingenayo insimbi namapulasitiki.

Izindlela zokuxhuma ezivamile ngamapayipi zihlanganisa ukushisela okuqondile, uxhumano lwe-flange, uxhumano lwe-hot melt, uxhumano lwe-electric melt, uxhumano lwezintambo kanye nokuxhumeka kwe-socket.

Ukusetshenziswa kwendololwane yensimbi engagqwali

Indololwane yensimbi engagqwali ngenjongo evamile igoqwa yinsimbi evamile ye-carbon structural, insimbi yesakhiwo sengxubevange ephansi noma insimbi yesakhiwo sengxubevange, ephumayo enkulu, futhi isetshenziswa kakhulu njengepayipi noma ingxenye yesakhiwo yokuthutha uketshezi.

Izinyathelo zokuqapha ukusetshenziswa kwendololwane yensimbi engagqwali

I-1.Ngesikhathi sokufakwa, i-elbow yensimbi engagqwali ingafakwa ngokuqondile kwipayipi ngokusho kwemodi yokuxhuma, noma ingafakwa ngokuvumelana nesimo sokusebenzisa. Ngaphansi kwezimo ezijwayelekile, ingafakwa noma kuphi epayipini, kodwa idinga ukuvalwa ukuze kuvinjwe ukuvuza okuguquguqukayo futhi kuthinte ukusebenza okuvamile kwepayipi.
2.Lapho kusetshenziswa i-valve yebhola, i-globe valve ne-valve yesango enendololwane yensimbi engagqwali, ingavulwa noma ivalwe ngokugcwele. Azivunyelwe ukuthi zisetshenziselwe ukulawula ukugeleza ukugwema ukuvala uphawu.
3.Ngokugcinwa kwe-elbow yensimbi engagqwali isikhathi eside, ukuhlolwa okuvamile kuzokwenziwa. Izindawo eziveziwe ezenziwe ngomshini kufanele zigcinwe zihlanzekile, ukungcola kufanele kukhishwe futhi kugcinwe kahle endaweni engenawo umoya futhi eyomile endlini. Kwenqatshelwe ngokuphelele ukupakisha nokugcina endaweni evulekile. Ngaso sonke isikhathi gcina indololwane yensimbi engenasici yomile futhi ingenisa umoya, gcina indololwane ihlanzekile futhi icocekile, futhi uyigcine ngendlela enembile yokugcina.

Inkambu yesicelo sendololwane yensimbi engagqwali

Indololwane yensimbi engagqwali isetshenziswa kabanzi ku-petroleum, embonini yamakhemikhali, embonini yamandla enuzi, ukukhiqiza ukudla, ukwakhiwa, ukwakha imikhumbi, ukwenza iphepha, imithi kanye nezinye izimboni. Inokusetshenziswa okuhlukile ezimbonini ezahlukahlukene futhi ikhombisa inani layo lokusetshenziswa ezimbonini ezahlukahlukene.

Umehluko phakathi kwendololwane yensimbi engagqwali kanye nendololwane ye-carbon steel

Umehluko omkhulu phakathi kwendololwane yensimbi engagqwali kanye nendololwane ye-carbon steel yizinto ezibonakalayo. Ukwakheka kwayo kwamakhemikhali kuzogcina indololwane ingagqwali nokugqwala isikhathi eside. Ingaguqulelwa ku:
1. Izindlela zokukhiqiza: ukusunduza, ukucindezela, ukufoja, ukuphonsa, njll.
2. Izindinganiso zokukhiqiza: indinganiso kazwelonke, indinganiso yomkhumbi, indinganiso kagesi, indinganiso yamanzi, indinganiso yaseMelika, indinganiso yesiJalimane, indinganiso yaseJapane, indinganiso yesiRashiya, njll.

Isilinganiso Sokucindezela

Sch5s,Sch10s,Sch10,Sch20,Sch30,Sch40s,STD,Sch40,Sch60、Sch80s、XS; Sch80,SCH100,Sch120、Sch140、Sch160、XXS;

Okuvame ukusetshenziswa kakhulu yi-STD ne-XS.

Idatha ye-Dimensional

Izindaba Ezidinga Ukunakwa

I-1.Ngesikhathi sokufakwa, i-elbow yensimbi engagqwali ingafakwa ngokuqondile epayipini ngokusho kwemodi yokuxhuma futhi ifakwe ngokuvumelana nesimo sokusetshenziswa. Ngokuvamile, ingafakwa kunoma iyiphi indawo yepayipi, kodwa idinga ukuvala ukuvimbela ukuvuza futhi kuthinte ukusebenza okuvamile kwepayipi.

2. Uma usebenzisa ama-valve ebhola lendololwane yensimbi engagqwali, ama-valve eglobhu nama-valve esango, asetshenziselwa kuphela ukuvulwa okugcwele noma ukuvala ngokugcwele. Azivunyelwe ukuthi zisetshenziselwe ukulungiswa kokugeleza ukuze kugwenywe ukuvala uphawu.

3.Indololwane yensimbi engagqwali egcinwe isikhathi eside izohlolwa ngesikhathi esimisiwe. Indawo yokucubungula eveziwe kufanele ihlale ihlanzekile, futhi ukungcola kuzosuswa. Kufanele igcinwe kahle endaweni engenawo umoya futhi eyomile endlini. Ukupakisha noma ukugcina ngaphandle kunqatshelwe ngokuphelele. Ngaso sonke isikhathi gcina indololwane yensimbi engenasici yomile futhi ingenisa umoya, gcina indololwane ihlanzekile futhi icocekile, futhi uyigcine ngendlela enembile yokugcina.

Amacebiso: Kunezinto eziningi okufanele uzinake uma kusetshenziswa izindololwane zensimbi engagqwali. Abasebenzisi kufanele bawasebenzise ngendlela ethile, futhi bawasebenzise futhi bawagcine ngendlela enembile nenengqondo.
