I-API 607 ​​​​xa ithelekiswa ne-API 608: Ukukhetha iValve yeBhola eLungileyo

Ukuqonda umahluko phakathiI-API 607kunyeI-API 608imigangatho ibalulekile xa ukhetha ivalvu yebhola efanelekileyo kwisicelo sakho semizi-mveliso. Le migangatho ilawula ukusebenza, ukhuseleko, kunye nokuthembeka kweevalvu zebhola, eziyinxalenye ebalulekileyo kwiinkqubo ezahlukeneyo zemibhobho. Kweli nqaku, siza kuhlola umahluko ophambili phakathi kwe-API 607 ​​​​kunye ne-API 608, impembelelo kumaxabiso evalvu yebhola, kunye nendima yabavelisi, ingakumbi eTshayina, ekuboneleleni ngomgangatho ophezulu.iivalvu zebhola.

Ukuqonda iMigangatho ye-API

I-API, okanye i-American Petroleum Institute, ibeka imigangatho kwishishini leoyile negesi, kuquka iinkcukacha zeevalvu. I-API 607 ​​​​kunye ne-API 608 yimigangatho emibini ebalulekileyo egxile kukhuseleko lomlilo kunye neemfuno ngokubanzi zeevalvu zebhola, ngokwahlukeneyo.

I-API 607: Uvavanyo loMlilo lweeValvu zeZitulo ezithambileyo zokujika ikota

Umgangatho we-API 607, uchaza iimfuno zovavanyo lomlilo kwiivalvu ezithambileyo zekota-turn, kuquka iivalvu zebhola. Lo mgangatho ubaluleke kakhulu kwizicelo ezifuna ukhuseleko lomlilo, ezifana nomzi-mveliso weoyile negesi. Iimpawu eziphambili ze-API 607 ​​ziquka:

1. Ukumelana nomliloIivalvu ezihlangabezana nemigangatho ye-API 607 ​​ziyavavanywa ukuqinisekisa ukuba ziyakwazi ukumelana namaqondo obushushu aphezulu kwaye zithintele ukuvuza xa kutsha.
2. Uyilo lwesihlalo esithambileyo: Lo mgangatho usebenza kwiivalvu ezinezihlalo ezithambileyo, ezihlala zenziwe ngezinto ezifana ne-PTFE okanye ii-elastomers. Ezi zinto zineempawu ezilungileyo zokutywina kodwa zichaphazeleka lula ngamaqondo obushushu aphezulu.
3. Iiprotokholi zovavanyoI-API 607 ​​icacisa iindlela zokuvavanya ezingqongqo ukuvavanya ukusebenza kweevalvu phantsi kweemeko zomlilo, ukuqinisekisa ukuba zigcina ukuthembeka nokusebenza kwazo.

I-API 608: Iivalvu zebhola ezihlala ngentsimbi

I-API 608 igxile kwiimfuno eziqhelekileyo zeevalvu zebhola ezihlala kwisinyithi. Umgangatho usebenza kwiivalvu ezenzelwe ukusetyenziswa koxinzelelo oluphezulu kunye nobushushu. Izinto eziphambili ze-API 608 ziquka:

1. Uyilo lwesihlalo sesinyithiNgokungafaniyo ne-API 607, egubungela iivalvu ezithambileyo, i-API 608 igubungela iivalvu ezihlala ngentsimbi. Ezi valve zihlala ziqinile kwaye zinokumelana neemeko ezinzima.
2. Imigangatho Yokusebenza: I-API 608 ichaza imigangatho yokusebenza yokuvuza, uxinzelelo, kunye nokulinganiswa kobushushu, iqinisekisa ukuba iivalvu zinokusebenza ngokufanelekileyo kwiindawo ezifuna amandla.
3. Ukuguquguquka: Iivalvu zebhola ezifakwe kwisinyithi zisetyenziswa rhoqo kumashishini ahlukeneyo, kuquka ukucubungula iikhemikhali, ukuvelisa umbane, kunye nokucoca amanzi, ngenxa yokuba ziqinile kwaye zithembekile.

Ukukhetha Phakathi kwe-API 607 ​​kunye ne-API 608

Xa ukhetha phakathiI-API 607kunyeIivalvu zebhola ze-API 608, cinga ngoku kulandelayo:

1. Iimfuno zeSiceloUkuba isicelo sakho siquka amaqondo obushushu aphezulu kunye neengozi zomlilo ezinokubakho, iivalvu ze-API 607 ​​​​zingcono. Kwizicelo ezifuna ukumelana noxinzelelo oluphezulu kunye namaqondo obushushu ngaphandle kweengozi zomlilo, iivalvu ze-API 608 zinokuba zifanelekile ngakumbi.
2. Izinto Eziqwalaselweyo: Ukukhetha izinto kubalulekile. Iivalvu ezithambileyo (API 607) zinokuba semngciphekweni wokonakala phantsi kweemeko ezinzima, ngelixa iivalvu ezifakwe ngentsimbi (API 608) zinika ukuqina okukhulu.
3. Impembelelo yeendleko: Ngokubanzi, iivalvu ze-API 607 ​​​​zinokuba zibiza kakhulu ngenxa yovavanyo olongezelelweyo lomlilo kunye nesatifikethi esifunekayo. Nangona kunjalo, ukonga kwexesha elide ngenxa yokugcinwa okunciphileyo kunye nokhuseleko oluphuculweyo kunokuqinisekisa utyalo-mali olukhulu lokuqala.
4. Udumo loMvelisi weValve: Kubalulekile ukukhetha umenzi othembekileyo. Khangela umenzi olandela imigangatho ye-API kwaye onembali eqinisekisiweyo yokuvelisa iivalvu zebhola ezikumgangatho ophezulu.

Ixabiso leValve yeBhola

Ixabiso levalvu yebhola lingahluka kakhulu ngokusekelwe kwizinto ezininzi, kuquka:

1. Izinto eziphathekayoUhlobo lwezinto ezisetyenzisiweyo ekwakheni iivalvu (umz., intsimbi engatyiwayo, intsimbi yekhabhoni, okanye ii-alloys ezingaqhelekanga) zinokuchaphazela ixabiso.
2. Ubungakanani kunye neenkcukacha: Iivalvu ezinkulu okanye iivalvu ezinemilinganiselo ethile yoxinzelelo kunye nobushushu ngokubanzi zibiza kakhulu.
3. IsiqinisekisoIivalvu ezihlangabezana nemigangatho ye-API 607 ​​okanye ye-API 608 zinokuba neprimiyamu ngenxa yenkqubo yovavanyo oluqatha kunye nesatifikethi ebandakanyekayo.
4. Umvelisi weValve yeBholaAmaxabiso anokwahluka ngokusekwe kwigama kunye nendawo yomenzi. Umzekelo, iTshayina ibe ngumdlali ophambili kushishino lokuvelisa iivalvu zebhola, inikezela ngamaxabiso akhuphisanayo ngelixa igcina umgangatho.

Indima yabavelisi beValve yeBhola yaseTshayina

I-China ibe ngumvelisi okhokelayo kwicandelo leevalvu zebhola, ivelisa uluhlu olubanzi lweemveliso ezihlangabezana nemigangatho eyahlukeneyo yamazwe ngamazwe, kubandakanya i-API 607 ​​​​kunye ne-API 608.
