1. Inkcazo esisiseko kunye noLwakhiwo
Ivalve yebhabhathane ethambileyo etywiniweyo (ekwabizwa ngokuba yi "center-line butterfly valve") yivalve ejikelezayo yekota eyilelwe ukulayita/ukucima okanye ukulawula ukuqukuqela okugobhozayo kwimibhobho. Iimpawu zayo eziphambili ziquka:
Uyilo oluNxibelelwano: Isiqu sevalve, idiski, kunye nesihlalo zilungelelaniswe kwi-axis esembindini enye, zenza ulwakhiwo olulula kunye nolubambeneyo.
Indlela yokutywina ethambileyo: Isitywina esiguquguqukayo se-elastomeric (umzekelo, irabha, i-EPDM, i-NBR) idityaniswe kumzimba wevalvu okanye isihlalo, ibonelela ngesitywina esiqinileyo ukuthintela ukuvuza.
I-Flanged Ends: I-valve ixhotywe ngoqhagamshelwano olune-flanged, evumela ukufakwa lula kwimibhobho ehambelana nemigangatho efana ne-ANSI, i-DIN, okanye i-JIS.
2.Amacandelo Angundoqo
3. UmGaqo wokuSebenza
Isikhundla esivulekileyo: I-disc ijikeleza i-90° ukulungelelanisa nolwalathiso lokuhamba, ukunciphisa ukuhla koxinzelelo kunye nokuvumela ukuhamba okupheleleyo.
Indawo evaliweyo: I-disc ijikeleza ngasemva ukucinezela ngokuchasene netywina elithambileyo, idala ukuvala okuqinileyo. Uyilo olugxininisiweyo luxhomekeke kwi-elastic deformation yetywina ukufezekisa ukutywinwa, kuyenza isebenze kakhulu kwizicelo ezinoxinzelelo oluphantsi.
4. Iimpawu eziphambili kunye nezinto eziluncedo
Ukutywinwa okuQinisekileyo: Izitywina ezithambileyo zibonelela ngokugqwesileyo kokuxhathisa ukuvuza, zihlala zidibana nemigangatho eqinile ye-bubble (umzekelo, i-ANSI B16.104 iClass VI, ISO 15848-1).
Ukusebenza kweTorque ephantsi: Uyilo olugxininisiweyo kunye netywina eliguquguqukayo linciphisa ukungqubana, livumela ukusebenza ngesandla ngesandla okanye ukusetyenziswa kunye ne-actuator ekhaphukhaphu.
I-Compact kwaye iKhaphukhaphu: Xa kuthelekiswa neevalvu zesango okanye zeglowubhu, iivalvu zebhabhathane ezigxininisiweyo zincinci kwaye kulula ukuzifaka kwiindawo ezinyiniweyo.
Ixabiso-Ngempumelelo: Ulwakhiwo olulula kunye nokusetyenziswa kwezinto eziphantsi kwenza ukuba zifikeleleke kwiimfuno ezisisiseko zokulawula ukuhamba.
I-Versatile Media Compatibility: Ilungele amanzi, umoya, i-oyile, ulwelo olungadlekiyo, kunye nemithombo yeendaba yegranular (eneengubo ezimelana ne-abrasion).
5. IiNgcaciso zobuGcisa
Uxinzelelo loxinzelelo: Ngokuqhelekileyo uxinzelelo oluphantsi ukuya oluphakathi (umz., PN6-PN16 / Udidi 125-Iklasi ye-150).
Uluhlu lobushushu:
Ii-elastomers eziqhelekileyo (umz., NR, EPDM): -10°C ukuya kuma-90°C (14°F ukuya ku-194°F).
Iimpawu zobushushu obuphezulu (umz., Viton®, PTFE): -20°C ukuya kwi-150°C (-4°F ukuya ku-302°F).
Ukuthotyelwa kweMigangatho:
Uyilo: EN593, API 609, MSS SP-67.
I-Flange: ANSI B16.5, ANSI B16.10 DIN EN 1092-1,
Uvavanyo: API 598, (uvavanyo lokuvuza).
6. Izicelo
Ukutywina okuthambileyo kweevalvu zebhabhathane ezigxininisiweyo I-D341X-16Qzisetyenziswa ngokubanzi kwi:
Ubonelelo lwaManzi noGutyulo lwaManzi: Iinkqubo zamanzi zikamasipala, amaziko okucoca ugutyulo, kunye nothungelwano lokunkcenkceshela.
Iinkqubo zeHVAC: Ukulawulwa komoya, amanzi, okanye umphunga ekufudumezeni, ekungeneni komoya, nakwimeko yomoya.
Ishishini lokuTya kunye neSiselo: izicelo zococeko ezinezitywina ezihambelana ne-FDA (umzekelo, i-EPDM enemigangatho yokutya).
IiNkqubo zoShishino ngokuBanzi: Ukuphathwa kolwelo olungadlekiyo kwiikhemikhali, ephepheni, nakwizityalo ezixuba amayeza (kwimithombo yeendaba epholileyo kuphela).
Ulwakhiwo lwaselwandle kunye nolwakhiwo lweenqanawa: Ukuvula/ukuvala kulawulo lwamanzi olwandle okanye kwiinkqubo ze-ballast (ezinezixhobo ezinganyangekiyo kwi-corrosion).
7. Unyino kunye nokuqwalaselwa
Uxinzelelo kunye neMida yoBubushushu: Ayilungelanga uxinzelelo oluphezulu (umzekelo, >PN16) okanye izicelo zobushushu obugqithisileyo (umzekelo, umphunga ongaphezulu kwe-150°C).
Imingcipheko yoMhlwa: Amalungu esinyithi (umzekelo, imizimba yentsimbi) anokonakala kwindawo enobundlobongela; uphuculo kwintsimbi engenasici okanye izinto ezigqunyiweyo kwiimeko ezinzima.
I-Abrasive Media: Izitywina ezithambileyo zinokunxiba ngokukhawuleza kunye nolwelo olune-particle; qwalasela iivalve zebhabhathane ezitywiniweyo okanye ezinye izaleko ezongezelelweyo zokukhusela.
Ukukhetha iActuator: Kwivalvu yobubanzi obukhulu okanye ukusebenza rhoqo, sebenzisa i-pneumatic/hydraulic actuators ukuphepha ukudinwa ngesandla.
8. Ufakelo kunye noLondolozo
Ukuhlohla:
Qinisekisa ukuba iiflange zilungelelanisiwe kwaye iibholithi ziqinisiwe ngokufanayo ukuthintela ukuvuza.
Kuphephe ukufaka ivalve phantsi koxinzelelo olugqithisileyo lombhobho.
Ugcino:
Hlola rhoqo isitywina sokunxiba okanye ukuqhekeka, ngakumbi kwizicelo ezijikelezayo.
Lubricate isiqu kunye ne actuator ngamaxesha athile ukuqinisekisa ukusebenza kakuhle.
Faka indawo yesitywina ukuba kuvuza kuyenzeka; Uyilo oluthile luvumela ukutshintshwa kwetywina ngaphandle kokususa ivalve kumbhobho.
9. Iingcebiso zokuKhetha uMboneleli kunye neMveliso
Isiqinisekiso seMaterial: Qinisekisa ukuba amatywina ahlangabezana nemigangatho yoshishino (umzekelo, i-FDA yokutya, i-ATEX yendawo eqhumayo).
Iinketho zokwenza ngokwezifiso: Abanye ababoneleli banikezela ngoyilo lwe-anti-static, iimpawu ezikhuselekileyo emlilweni, okanye iingubo ezikhethekileyo (umzekelo, i-epoxy, i-PTFE) kwizicelo ze-niche.
Ukuqukumbela
Ukutywina okuthambileyo kweevalvu zebhabhathane ezigxininisiweyozisicombululo esinendleko, esithembekileyo solawulo lokuhamba koxinzelelo oluphantsi ukuya kwephakathi kwizicelo ezingabalulekanga. Ubulula babo, ukutywinwa okuqinileyo, kunye nokugcinwa lula kubenza babe lukhetho oludumileyo emanzini, i-HVAC, kunye neenkqubo zoshishino jikelele. Kwiindawo ezifuna kakhulu, uphuculo kuyilo lwe-eccentric okanye imathiriyeli yeprimiyamu kuyacetyiswa. Hlala uvavanya iipropati zemidiya, iimeko zokusebenza, kunye neemfuno zokuthotyelwa ukukhetha ivalve efanelekileyo kwiimfuno zakho.
Nayiphi na irabha ehleli ngokucokisekileyoivelufa butterfly, njengevalve yebhabhathane, ivalve yebhabhathaneI-D7L1X-16Q, i-Y-strainer, ivalve yokujonga i-wafer,ivalve yesangoI-Z41X-16Qiimfuno, unokunxibelelana neIvalve ye-TWSumzi-mveliso, siya kukuphendula okokuqala.
