API 607 ​​​​motsutsana ndi API 608: Kusankha Valavu Yabwino ya Mpira

Kumvetsetsa kusiyana pakati paAPI 607ndiAPI 608miyezo ndi yofunika kwambiri posankha valavu yoyenera ya mpira yomwe mungagwiritse ntchito m'mafakitale. Miyezo iyi imayang'anira magwiridwe antchito, chitetezo, komanso kudalirika kwa mavalavu a mpira, omwe ndi zinthu zofunika kwambiri m'njira zosiyanasiyana zopaipira. M'nkhaniyi, tifufuza kusiyana kwakukulu pakati pa API 607 ​​​​ndi API 608, momwe mitengo ya mavalavu a mpira imakhudzira, komanso udindo wa opanga, makamaka ku China, popereka zinthu zapamwamba kwambiri.mavavu a mpira.

Kumvetsetsa Miyezo ya API

API, kapena American Petroleum Institute, imakhazikitsa miyezo yamakampani amafuta ndi gasi, kuphatikiza ma valavu. API 607 ​​​​ndi API 608 ndi miyezo iwiri yofunika kwambiri yomwe imayang'ana kwambiri chitetezo chamoto ndi zofunikira zonse zamavalavu a mpira, motsatana.

API 607: Kuyesa Moto kwa Ma Vavu Ozungulira Malo Ofewa

Muyezo wa API 607, umafotokoza zofunikira pakuyesa moto kwa ma valve ozungulira kotala la mipando yofewa, kuphatikiza ma valve a mpira. Muyezo uwu ndi wofunikira kwambiri pa ntchito zomwe zimafuna chitetezo cha moto, monga makampani amafuta ndi gasi. Zinthu zazikulu za API 607 ​​ndi izi:

1. Kukana motoMa valve omwe amakwaniritsa miyezo ya API 607 ​​​​amayesedwa kuti atsimikizire kuti amatha kupirira kutentha kwambiri ndikuletsa kutayikira pakagwa moto.
2. Kapangidwe ka mipando yofewa: Muyezowu umagwira ntchito pa ma valve okhala ndi mipando yofewa, yomwe nthawi zambiri imapangidwa ndi zinthu monga PTFE kapena elastomers. Zipangizozi zimakhala ndi mphamvu zabwino zotsekera koma zimakhudzidwa mosavuta ndi kutentha kwambiri.
3. Ma protocol oyesera: API 607 ​​​​imatchula njira zoyesera zolimba kuti ziwunikire momwe ma valve amagwirira ntchito pamoto, kuonetsetsa kuti akusunga umphumphu ndi magwiridwe antchito.

API 608: Ma valve a mpira okhala ndi zitsulo

API 608 imayang'ana kwambiri zofunikira zonse zama valve a mpira okhala ndi zitsulo. Muyezowu umagwiranso ntchito pama valve omwe amapangidwira kupanikizika kwakukulu ndi kutentha. Zinthu zofunika kwambiri za API 608 ndi izi:

1. Kapangidwe ka mipando yachitsuloMosiyana ndi API 607, yomwe imaphimba mavavu okhala ndi mipando yofewa, API 608 imaphimba mavavu okhala ndi mipando yachitsulo. Mavavu amenewa nthawi zambiri amakhala olimba kwambiri ndipo amatha kupirira zovuta kwambiri.
2. Miyezo Yogwirira Ntchito: API 608 imafotokoza miyezo yogwirira ntchito ya kutayikira, kuthamanga, ndi kutentha, kuonetsetsa kuti ma valve amatha kugwira ntchito bwino m'malo ovuta.
3. Kusinthasintha: Ma valve a mpira okhala ndi zitsulo amagwiritsidwa ntchito nthawi zambiri m'mafakitale osiyanasiyana, kuphatikizapo kukonza mankhwala, kupanga magetsi, ndi kuyeretsa madzi, chifukwa cha kulimba kwawo komanso kudalirika kwawo.

Kusankha Pakati pa API 607 ​​​​ndi API 608

Mukasankha pakati paAPI 607ndiMa valve a mpira a API 608, taganizirani izi:

1. Zofunikira pa NtchitoNgati ntchito yanu ikuphatikizapo kutentha kwambiri komanso zoopsa zamoto, ma valve a API 607 ​​​​ndi chisankho chabwino. Pa ntchito zomwe zimafuna kukana kupsinjika kwakukulu komanso kutentha popanda zoopsa zamoto, ma valve a API 608 angakhale oyenera kwambiri.
2. Zofunika Kuganizira: Kusankha zinthu n'kofunika kwambiri. Ma valve okhala ndi mipando yofewa (API 607) akhoza kuwonongeka mosavuta pakakhala zovuta kwambiri, pomwe ma valve okhala ndi mipando yachitsulo (API 608) amapereka kulimba kwambiri.
3. Zotsatira za Mtengo: Kawirikawiri, ma valve a API 607 ​​​​angakhale okwera mtengo kwambiri chifukwa cha mayeso owonjezera a moto ndi satifiketi yofunikira. Komabe, kupulumutsa kwa nthawi yayitali kuchokera pakuchepetsa kukonza ndi chitetezo chabwino kungapangitse kuti ndalama zoyambira zikhale zapamwamba.
4. Mbiri ya Wopanga Ma VavuNdikofunikira kusankha wopanga wodalirika. Yang'anani wopanga yemwe amatsatira miyezo ya API ndipo ali ndi mbiri yotsimikizika yopanga ma valve apamwamba kwambiri.

Mtengo wa Valavu ya Mpira

Mtengo wa valavu ya mpira ukhoza kusiyana kwambiri kutengera zinthu zingapo, kuphatikizapo:

1. Zinthu Zofunika: Mtundu wa zinthu zomwe zimagwiritsidwa ntchito popanga ma valavu (monga chitsulo chosapanga dzimbiri, chitsulo cha kaboni, kapena zinthu zina zachilendo) zingakhudze mtengo.
2. Kukula ndi Kufotokozera: Ma valve akuluakulu kapena ma valve okhala ndi kupanikizika ndi kutentha kwapadera nthawi zambiri amakhala okwera mtengo kwambiri.
3. ChitsimikizoMa valve omwe amakwaniritsa miyezo ya API 607 ​​​​kapena API 608 akhoza kukhala ndi mtengo wapamwamba chifukwa cha mayeso ovuta komanso njira yovomerezeka.
4. Wopanga Valavu ya MpiraMitengo imathanso kusiyana kutengera mbiri ndi malo a wopanga. Mwachitsanzo, China yakhala mtsogoleri pamakampani opanga ma valve a mpira, ikupereka mitengo yopikisana komanso ikusunga mtundu wake.

Udindo wa Opanga Ma Valve a Mpira aku China

China yakhala kampani yotsogola kwambiri pakupanga ma valve a mpira, ndikupanga zinthu zosiyanasiyana zomwe zimakwaniritsa miyezo yosiyanasiyana yapadziko lonse lapansi, kuphatikiza API 607 ​​​​ndi API 608.
