Nhanganyaya: Sei zviyero zveAPI zvakakosha kune mavharuvhu eindasitiri?
Mumaindasitiri ane njodzi zvakanyanya semafuta uye gasi, makemikari uye simba, kuchengetedzwa uye kuvimbika kwemavharuvhu kunogona kukanganisa zvakananga kugadzikana kwemaitiro ekugadzira. Izvo zviyero zvakatarwa neAPI (American Petroleum Institute) ndiro bhaibheri rehunyanzvi remavharuvhu emaindasitiri pasi rese. Pakati pavo, API 607 uye API 608 ndiwo makiyi akatsanangurwa anowanzo kutaurwa nevainjiniya nevatengi.
Ichi chinyorwa chichaongorora zvakadzama misiyano, mamiriro ekushandisa uye mapoinzi ekuteerera eaya maviri zviyero.
Chitsauko 1: Kududzirwa kwakadzama kweAPI 607 chiyero
1.1 Yakajairika tsananguro uye yakakosha mishoni
API 607 "Moto bvunzo kutsanangurwa kwe1/4 kutendeuka mavharuvhu uye asiri-simbi-simbi vharafu chigaro mavharuvhu" inotarisa pakuona yekuisa chisimbiso kushanda kwemavharuvhu pasi pemamiriro emoto. Iyo yazvino 7th edition inowedzera tembiricha yekuyedza kubva pa1400°F (760°C) kuenda pa1500°F (816°C) kutevedzera mamwe akanyanya kuoma moto.
1.2 Tsananguro yakadzama yeakakosha bvunzo paramita
- Nguva yemoto: 30 maminetsi ekuramba achipisa + 15 maminetsi enguva yekutonhora
-Leakage rate standard: Yakanyanya kubvumidzwa kuvuza haipfuure ISO 5208 Rate A
-Muyedzo wepakati: Musanganiswa bvunzo yegasi rinopisa (methane / gasi rechisikigo) uye mvura
- Mamiriro ekudzvinyirira: Dynamic bvunzo ye80% yeyakayerwa kudzvanywa
Chitsauko 2: Kuongororwa kwehunyanzvi kweAPI 608 standard
2.1 Yakajairwa chinzvimbo uye chiyero chekushandisa
API 608 "Metal bhora mavharuvhu ane flange ends, thread ends and welding ends" inomisa zvinodiwa zvehunyanzvi zvehurongwa hwese kubva pakugadzira kusvika pakugadzira mavharuvhu ebhora, inovhara saizi yemhando yeDN8~DN600 (NPS 1/4~24), uye mwero wekumanikidza ASME CL150 kusvika 2500LB.
2.2 Core dhizaini zvinodiwa
- Valve muviri chimiro: imwe-chidimbu / kupatsanurwa kukanda maitiro maitiro
-Sisitimu yekuisa chisimbiso: zvinosungirwa zvinodiwa kune kaviri block uye kubuda ropa (DBB) basa
- Operating torque: yakanyanya kushanda simba haipfuure 360N · m
2.3 Zvinhu zvakakosha zvekuyedza
- Shell simba bvunzo: 1.5 nguva yakayerwa kudzvanywa kwemaminetsi matatu
-Kuisa chisimbiso bvunzo: 1.1 nguva yakatarwa kudzvanywa bidirectional bvunzo
- Hupenyu hwekutenderera: angangoita zviuru zvitatu zvekuvhura uye kuvhara kushanda kwekuongorora
Chitsauko 3: Misiyano mishanu pakati peAPI 607 ne API 608
| Kuenzanisa zviyero | API 607 | API 608 |
| Standard positioning | Fire performance certification | Magadzirirwo echigadzirwa uye maitiro ekugadzira |
| Applicable stage | Product certification stage | Iyo yese dhizaini nekugadzira maitiro |
| Test method | Inoparadza moto simulation | Zvakajairwa kumanikidza / kushanda bvunzo |
Chitsauko 4: Sarudzo yekusarudza engineering
4.1 Inosungirwa kusanganiswa kwenzvimbo dzine njodzi huru
Kune mapuratifomu ekumahombekombe, LNG zviteshi uye dzimwe nzvimbo, zvinokurudzirwa kusarudza:
API 608 bhora vharafu + API 607 chitupa chekudzivirira moto + SIL chengetedzo level certification
4.2 Mutengo wekugadzirisa mhinduro
Kune akajairwa mamiriro ekushanda, unogona kusarudza:
API 608 yakajairwa vharafu + yemuno kudzivirira moto (senge isina moto coating)
4.3 Yambiro yekusanzwisisana kwesarudzo
- Tenda zvisiri izvo kuti API 608 inosanganisira zvinodiwa zvekudzivirira moto
-Kuenzanisa API 607 kuyedza neyakajairwa yekuisa chisimbiso bvunzo
-Kuregeredza fekitori kuongororwa kwezvitupa (API Q1 system zvinodiwa)
Chitsauko 5: Mibvunzo Inowanzo bvunzwa (FAQ)
Q1: Ko iyo API 608 vharafu inongosangana neiyo API 607 inodiwa?
A: Kwete chokwadi zvachose. Kunyangwe API 608 bhora mavharuvhu anogona kunyorera API 607 certification, anofanirwa kuongororwa zvakasiyana.
Q2: Ivhavha inogona kuramba ichishandiswa mushure mekuedzwa kwemoto here?
A: Hazvikurudzirwi. Mavharuvhu mushure mekuedzwa kazhinji ane kukuvara kwechimiro uye anofanirwa kuraswa.
Q3: Izvo zviyero zviviri zvinokanganisa sei mutengo wevhavha?
A: API 607 certification inowedzera mutengo ne30-50%, uye API 608 kutevedzera kunokanganisa nezve 15-20%.
Mhedziso:
• API 607 yakakosha pakuedza moto kwemavharuvhu e-soft-seat butterfly nemavharuvhu ebhora.
• API 608 inovimbisa kurongeka uye kushanda kwekuvimbika kwesimbi-seat uye soft-seat bhora mavharuvhu anoshandiswa mumaindasitiri ekushandisa.
• Kana kuchengetedzwa kwemoto kuri iko kutariswa kwekutanga, mavharuvhu anoteerana neAPI 607 yakajairwa anodiwa.
• Nokuda kwechinangwa chikuru uye kushandiswa kwevhavha yepamusoro-soro, API 608 ndiyo chiyero chakakodzera.
