Chii chinonzi API 600 Gate Valve?
API 600 chiyero chechigadzirwa chakaburitswa neAmerican Petroleum Institute. Zita rayo rakazara ndi *Mavharuvhu eSimbi - Magumbo eKuputira Akaputirwa uye Akasungirirwa, Mabhoneti Akasungwa*. Yakaburitswa kekutanga muna 1949, yakagadzirwa zvakanangana nebasa rakaoma muzviteshi zvekuchenesa mafuta negasi rechisikigo.
Mutemo uyu unovhara makirasi ekumanikidzwa kubva kuKirasi 150 kusvika kuKirasi 2500 uye saizi kubva kuNPS 2 kusvika kuNPS 48. Unotsanangura zvinodiwa zvehunyanzvi zvinopfuura makumi maviri, zvinosanganisira zvinhu, ukobvu hwemadziro, dhayamita yemudzi, kushanda kwekuvhara, kusimba kwekupisa kwakaderera, uye kuchengetedzwa kwemoto. Chinyorwa chazvino (API STD 600:2021) chinosimbisa kudiwa kwekugadzirwa kwemadziro akazara, ukobvu hwemadziro anorema, uye dhayamita hombe.
Chii chinonzi ASME B16.34 Gate Valve?
ASME B16.34 imhando yevharuvhu yakagadzirwa neAmerican Society of Mechanical Engineers. Inoshanda kumavharuvhu ekupedzisira ane flange, threaded, uye welding emhando dzese dzakajairika - gedhi, globe, check, ball, uye butterfly valves.
Kusiyana neAPI 600, iyo inongovhara mavharuvhu egedhi chete, ASME B16.34 inopa zviyero zvekupisa kwemhepo, mapoka emidziyo (49 ese), mafomura eukobvu hwemadziro, mitemo yekumaka, uye zvinodiwa pakuyedza. Inotangira paKirasi 150 kusvika kuKirasi 4500, uye inoshanda pakupisa kubva -29°C kusvika pamusoro pe500°C, zvichienderana nemidziyo yacho.
Kusiyana Kwemaumbirwo Pakati peAPI 600 neASME B16.34 Gate Valves
Maitiro maviri aya akafanana pakutanga, asi magadzirirwo awo emukati akasiyana zvakanyanya.
Ukobvu hwemadziro
ASME B16.34 inotsanangura kutizvishomaukobvu hwemadziro hunodiwa kuti kudzvanywa kwemhepo kugare kwakachengeteka. Izvi zvinoita kuti mavharuvhu agare akareruka uye asingadhuri.
Zvinodiwa zveAPI 600ukobvu hwemadziro hwakawedzerwa– kazhinji kacho inenge 20% yakawedzerwa – izvo zvinoshanda semubhadharo wengura yakavakirwa mukati. Simbi iyoyo inowedzera hupenyu hwebasa munzvimbo dzinocheneswa nemafuta.
Dhizaini yeHunde
API 600 inodatsinde rakaomarara, rakaomararaine dhayamita yakakura kupfuura zvinodiwa. Izvi zvinodzivirira kukotama kana paine kumanikidzwa kwakanyanya kana kuti wedge inonamira nekuda kwekuwedzera kwekupisa kana marara.
ASME B16.34 haimanikidze hunde yakasimba; vagadziri vanogona kusarudza magadzirirwo anochinjika kana application ichibvumira.
Kubatanidza Bhoneti
Mavharuvhu egedhi eAPI 600 anowanzo shandisa bhoneti rine mabhaudhi kana bhoneti rine pressure seal. Rudzi rwepressure seal runova rwakasimba kana kumanikidzwa kwemukati kuchikwira - zvakanaka kune tembiricha yakakwira uye kumanikidzwa kwakakwira.
ASME B16.34 inosiya mhando yebhoneti yakavhurika, zvichipa vagadziri rusununguko rwakawanda.
Rudzi rwekuisa chisimbiso
API 600 inodachisimbiso chesimbi kubva kusimbiine jira rakasimba (semuenzaniso, Stellite) pachigaro nepachivharo. Izvi zvinobata tembiricha yakakwira uye zvidimbu zvakazadzwa nemidziyo.
ASME B16.34 inobvumira zvisimbiso zvakapfava kana zvisimbiso zvesimbi, zvichienderana nekugadzirwa kwemugadziri.
Rudzi rweWedge uye Saizi yeBore
Mavharuvhu egedhi eAPI 600 anenge aripo nguva dzoseyakazara(full port) kuderedza kuramba kuyerera kwemvura uye kudzivirira kuungana kwemarara. Wedge iyi inowanzova wedge yakasimba kana inochinjika.
ASME B16.34 inobvumira magadzirirwo emadziro akaderedzwa chero bedzi nzvimbo shoma yekuyerera kwemvura ichizadzisa zvinodiwa zvekuchengetedza.
Huremu hwese
Nekuda kwemadziro akareruka, hunde hombe, uye bhoneti yakaoma,Vharuvhu yegedhi yeAPI 600inorema inenge 20% kupfuuravharuvhu yegedhi yeASME B16.34yehukuru hwakaenzana uye kirasi yekumanikidzwa. Musiyano iwoyo wehuremu imhedzisiro yakananga yepfungwa dzakasiyana dzekugadzira.
Mamiriro Ekushanda - Apo Standard Yega Yega Inobudirira
Basa Rakajairika remavharuvhu egedhi eAPI 600
Uchawana mavharuvhu egedhi eAPI 600 mumasevhisi akaomarara eindasitiri:
- Nzvimbo dzekuchenesa mafuta– catalytic cracking, hydrocracking, uye coker units uko media ine sarufa, mahydrocarbons anodziya zvakanyanya, kana catalyst fines.
- Masisitimu emhepo ine simba guru– pamusoro pe5 MPa (inenge 725 psi), zvakaita semitsetse mikuru yemhepo muzviteshi zvemagetsi.
- Kuyerera kwakazara nezvinhu zvakasimba zvinopisa zvakanyanya– mvura dzinotakura zvidimbu zvecoke kana guruva re catalyst.
- Nzvimbo dzinopisa moto- chigaro chesimbi chinopa dziviriro yemoto isina chitupa chekuwedzera.
Basa Rakajairika remavharuvhu egedhi eASME B16.34
Mavharuvhu egedhi eASME B16.34 anofukidza huwandu hwakakura hweindasitiri:
- Kurapa nemvura uye HVAC– mhepo ine simba shoma, yakachena kusvika pakupisa kweClass 600 ne425°C.
- Mitsetse yemakemikari- pane sarudzo dzakawanda dzezvinhu zviripo, asi pasina mamwe magadzirirwo ekuchengetedza eAPI 600.
- Masisitimu ekubatsira emagetsi– mvura inotonhorera, mafuta ekuzora, uye utsi hwemhepo husina simba.
- Kutapurirana kwemafuta negesi kwakajairika- uko kusina kukanganiswa kukuru kwevhu kana njodzi yemoto.

Maitiro Ekusarudza Pakati peAPI 600 neASME B16.34 Gate Valves
Chinokosha kunzwisisa izvozvoAPI 600 inovakwa pamusoro peASME B16.34Vharuvhu yegedhi yeAPI 600 inofanirawo kusangana nemazinga ekupisa ekumanikidzwa kweASME B16.34. Nemamwe mashoko, API 600 ndiyo **shanduro yakasimbiswa**nebasa rakaoma.
Sarudza API 600 kana:
- Nzvimbo iyi ine sarufa, hydrogen, catalyst fines, kana coke particles.
- Kumanikidzwa kwemhepo kunodarika 5 MPa (≈725 psi).
- Vharuvhu iri munzvimbo ine njodzi yemoto uye unoda kuchengetedzeka kwemoto.
- Pombi iyi ine kutenderera kwekupisa kana kudedera kunowanzoitika - hunde yakasimba uye madziro anorema anodzivirira kuneta.
Sarudza ASME B16.34 kana:
- Nzvimbo yacho imvura yakachena, mhepo, gasi risina simba, kana mafuta akareruka.
- Kirasi yekumanikidzwa iKirasi 150 kana Kirasi 300 isingakanganisi.
- Sisitimu iyi ndeye HVAC, mvura yemagetsi, kana mvura yemoto.
- Unoda vharuvhu isiri gedhi (globe, cheki, bhora) - saka ASME B16.34 ndiyo chiyero chako chekutanga.
Nyaya yakakosha - indasitiri yemagetsi:Mavharuvhu emagetsi ane simba rekumanikidza zvakanyanya anowanzoda API 600 neASME B16.34, pamwe chete nemimwe mitemo yakaita seASME B16.34 Class 4500 kana MSS SP‑144 yekushandira simba rekumanikidza zvakanyanya uye tembiricha yepamusoro.
Pfungwa Dzekupedzisira
API 600uyeASME B16.34havasi makwikwi - vanoita zvinangwa zvakasiyana. ASME B16.34 inopapasiyekugadzirwa kwemavharuvhu akachengeteka mumaindasitiri ese. API 600 inowedzera adenga rinoremayezvikamu zvemafuta, gasi, uye petrochemical.
Kana ukasarudza vharuvhu yegedhi yakajairika yemuchina wekuchenesa mvura kana tambo huru yemhepo, shandisa API 600. Huremu hwakawedzerwa uye mutengo zvinobhadhara pakuvimbika uye kuchengetedzeka.
Kana uchida vharuvhu yegedhi inoshandiswa pakushandisa mvura inotonhorera kana utsi hwemhepo husina kumanikidzwa zvakanyanya, ASME B16.34 yakakwana zvakakwana uye inodhura zvishoma.
Kunzwisisa hukama uhwu kunokubatsira kudzivirira kutsanangura zvakanyanya (kutambisa mari) kana kushaya kutsanangura zvakakwana (kuisa pangozi yekukundikana).
