Ukuthi ukukhethwa kwendlela yokuhlanganisa hlangana nevalvu ye-butterfly nephayiphi nofana imitjhini kulungile nofana awa kuzokuthinta ngqo amathuba wokusebenza, ukuthosa, ukuthosa nokuvuza kwevalvu yepayipi. Iindlela ezijayelekileko zokuhlanganisa ivalvu zifaka hlangana: ukuhlanganisa i-flange, ukuhlanganisa i-wafer, ukuhlanganisa ukuwelda kwe-butt, ukuhlanganisa nge-thread, ukuhlanganisa i-ferrule, ukuhlanganisa i-clamp, ukuhlanganisa ukuzivala namanye amafomu wokuhlanganisa.
A. Ukuxhumana kwe-flange
Ukuhlanganiswa kwe-flange kuyintoivalvu ye-butterfly eneflangwengamaflentjhi emaphethelweni womabili womzimba wevalvu, ahambelana namaflentjhi asephayiphini, begodu afakwa ephayiphini ngokubophelela amaflentjhi. Ukuxhumana kwe-flange yindlela yokuxhumana esetjenziswa khulu kumavalvu. Amaflentjhi ahlukaniswe abe yindawo evulekileko (RF), indawo ephakemeko (FF), indawo evulekileko nevulekileko (MF), njll.
B. Ukuxhumana kwe-wafer
Ivalvu ifakwe hlangana namafletjhi amabili, begodu umzimba wevalvui-wafer butterfly valvekanengi inembobo yokubeka ukusiza ukufakwa nokubeka.
C. Ukuxhumana kwe-solder
(1) Ukuhlanganiswa kokuwelda kwe-butt: Zombili iinphetho zomzimba wevalvu zisetjenziswa zibe ziindawo zokuwelda nge-butt ngokuya kweemfuneko zokuwelda ze-butt, ezihambelana nama-groove wokuwelda wepayipi, begodu zilungiswa epayipini ngokuwelda.
(2) Ukuhlanganiswa kokuwelda kwesokhethi: Zombili iinphetho zomzimba wevalvu zisetjenziswa ngokuya ngeemfuneko zokuwelda kwesokhethi, begodu zixhunywe nepayipi ngokutjheja kwesokhethi.
D. Ukuxhumana ngentambo
Ukuhlanganiswa okuneentambo yindlela elula yokuhlanganisa begodu kuvame ukusetjenziselwa amavalvu amancani. Umzimba wevalvu usetjenzwa ngokuya ngezinga lentambo ngayinye, begodu kunemihlobo emibili yentambo yangaphakathi nentambo yangaphandle. Ihambisana nentambo ephayiphini. Kunemihlobo emibili yokuhlanganiswa okuneentambo:
(1) Ukuvala ngqo: Iintambo zangaphakathi nezangaphandle zidlala indima yokuvala ngqo. Ukuqinisekisa bona ukuhlobana akuvuzi, kuvamise ukuzaliswa ngamafutha we-lead, i-hemp ye-thread kanye netheyiphu ye-PTFE; hlangana nalokho itheyiphu yezinto eziluhlaza ze-PTFE isetjenziswa khulu; into le inendlela ehle yokujamelana nokugqwala nomphumela omuhle khulu wokuvala. Kulula ukuyisebenzisa nokuyigcina. Lokha nayihlukaniswa, ingasuswa ngokupheleleko ngombana ayifilimu enganamatheli, engcono khulu kune-lead oyili kanye ne-hemp ye-thread.
(2) Ukuvala okungaqondileko: amandla wokuqinisa intambo adluliselwa ku-gasket hlangana namaplani amabili, ukwenzela bona i-gasket idlale indima yokuvala.
E. ukuxhumana kwe-ferrule
Ukuxhumana kwe-ferrule kwenziwa enarheni yami eminyakeni esanda kwedlula. Umthetho wokuhlanganisa nokuvala kwayo kukobana lokha nakuqiniswa i-nut, i-ferrule igandeleleka, ukwenzela bona umphetho we-ferrule ulume ebodeni langaphandle lepayipi, begodu ubuso bangaphandle be-ferrule buxhunywe ekuhlanganeni ngaphasi kwegandeleleko. Ingaphakathi lomzimba lithintana khulu nendawo encani, ngalokho ukuvuza kungavinjelwa ngokuthembekileko. Njengamavalvu weensetjenziswa. Iinzuzo zalolu hlobo lokuxhumana yilezi:
(1) Usayizi omncani, ubunzima obulula, isakhiwo esilula, ukuhlukaniswa nokuhlanganisa okulula;
(2) Amandla wokuhlanganisa aqinileko, ukusetjenziswa okubanzi, ukujamelana nokugandeleleka okuphezulu (1000 kg/cm 2), amazinga womtjhiso aphezulu (650 ° C) nokuthuthumela nokuthuthumela;
(3) Iinsetjenziswa ezihlukahlukeneko zingakhethwa, ezilungele ukulwisana nokugqwala;
(4) Iimfuneko zokunemba kwemitjhini aziphezulu;
(5) Ilungele ukufakwa endaweni ephakemeko.
Njenganje, ifomu lokuhlanganisa i-ferrule sele lamukelwe kweminye imikhiqizo yamavalvu anobubanzi obuncani enarheni yami.
F. Ukuxhumana okunemigodi
Le yindlela yokuhlanganisa msinyana, itlhoga amabhawudo amabili kwaphela, begoduivalvu yevithamini enomgodiilungele umfutho ophasiamavalvu wevithaminiezivamise ukuhlukaniswa. njengamavalvu wokuhlanza.
G. Ukuxhumana kwangaphakathi kokuziqinisa
Zoke iinhlobo zokuhlanganisa ezingenhla zisebenzisa amandla wangaphandle ukuqeda umfutho wendawo ukufikelela ukuvala. Okulandelako kuchaza indlela yokuxhumana yokuziqinisa ngokusebenzisa umfutho ophakathi.
Indandatho yayo yokuvala ifakwe ekhoneni yangaphakathi begodu yakha i-engeli ethileko lapho ihlangothi liqale phakathi. Umfutho we-medium udluliselwa ku-cone yangaphakathi bese uya eringini yokuvala. Phezu kwekhoni ye-engeli ethileko, kwakhiwa amandla amabili weengcenye, enye enelayini ephakathi yomzimba wevalvu ihambisana nengaphandle, kuthi enye igandelelwe ebodeni langaphakathi lomzimba wevalvu. Amandla wokugcina ngamandla wokuziqinisa. Nayikukhulu umfutho ophakathi, amandla wokuziqinisa ayaba makhulu. Ngalokho-ke, ifomu lokuhlanganisa lilungele amavalvu wegandeleleko eliphezulu.
Nayiqathaniswa nokuhlanganiswa kwe-flange, konga izinto ezinengi namandla wabantu, kodwana itlhoga ukulayisha okuthileko, ukwenzela bona isetjenziswe ngokuthembeka lokha umfutho we-valve ungaphezulu. Amavalvu enziwe ngokusebenzisa umthetho wokuziqinisa ngokuvamise ukuba mavalvu anegandelelo eliphezulu.
Kuneendlela ezinengi zokuhlanganisa amavalvu, isibonelo, amanye amavalvu amancani angatlhogi ukususwa ahlanganiswa ngamapayipi; amanye amavalvu angasiwo wensimbi ahlanganiswe ngamasokhethi njalonjalo. Abasebenzisi be-valve kufanele baphathwe ngokuya ngobujamo obuthileko.
Tjheja:
(1) Zoke iindlela zokuhlanganisa kufanele zibhekisele emazingeni ahambelanako begodu zicacise amazinga ukukhandela bona ivalvu ekhethiweko ingafakwa.
(2) Ngokuvamileko, ipayipi elikhulu nevalvu zihlanganiswa nge-flange, begodu ipayipi elincani nevalvu zihlanganiswe ngentambo.
