1. Inkcazelo esisiseko kunye nolwakhiwo
Ivalvu yebhabhathane ethambileyo etywiniweyo (ekwaziwa ngokuba yi-"center-line butterfly valve") yivalvu ejikelezayo yekota eyenzelwe ukuvala/ukuvula okanye ukulawula ukuhamba kwamanzi kwimibhobho. Iimpawu zayo eziphambili ziquka:
Uyilo oluyiConcentric: Isiqu sevalvu, idiski, kunye nesihlalo zilungelelaniswe kwi-axis enye esembindini, nto leyo eyenza isakhiwo esilula nesincinci.
Indlela Yokuvala Ethambileyo: Itywina eliguquguqukayo le-elastomeric (umz., irabha, i-EPDM, i-NBR) lifakwe emzimbeni wevalvu okanye kwisihlalo, nto leyo enika itywina eliqinileyo ukuthintela ukuvuza.
Iziphelo Ezijikelezileyo: Ivalvu ixhotyiswe ngoqhagamshelo olujikelezileyo, nto leyo evumela ukufakwa lula kwimibhobho ehambelana nemigangatho efana ne-ANSI, i-DIN, okanye i-JIS.
2.Izinto eziphambili
3. Umgaqo Wokusebenza
Indawo evulekileyo: Idiski ijikeleza i-90° ukuze ihambelane necala lokuhamba komoya, inciphise ukuhla koxinzelelo kwaye ivumele ukuhamba komoya ngokupheleleyo.
Indawo eValiweyo: Idiski ijika ibuyele umva ukuze icinezele isitywini esithambileyo, nto leyo eyenza ukuba ivale ngokuqinileyo. Uyilo oluqinileyo luxhomekeke ekuguqulweni kwe-elastic kwesitywini ukuze kufezekiswe ukutywinwa, nto leyo eyenza ukuba isebenze kakhulu kwizicelo ezinoxinzelelo oluphantsi.
4. Iimpawu eziphambili kunye neenzuzo
Ukutywina Okuqinileyo: Izitywina ezithambileyo zibonelela ngokumelana nokuvuza okugqwesileyo, zihlala zihlangabezana nemigangatho yokuxinana kwamaqamza (umz., i-ANSI B16.104 Class VI, ISO 15848-1).
Ukusebenza kweTorque ephantsi: Uyilo oluqinileyo kunye nesitywina esiguquguqukayo kunciphisa ukungqubana, okuvumela ukuba kube lula ukusebenza ngesandla okanye ukusetyenziswa ngee-actuators ezikhaphukhaphu.
Incinci kwaye Ilula: Xa ithelekiswa neevalvu zesango okanye zeglobe, iivalvu zebhabhathane ezixineneyo zincinci kwaye kulula ukuzifaka kwiindawo ezimbalwa.
Ixabiso Eliphantsi: Ulwakhiwo olulula kunye nokusetyenziswa okuncinci kwezinto zenza ukuba zifikeleleke kwiimfuno zolawulo lokuhamba kwamanzi.
Ukuhambelana kweMedia eSebenza ngeendlela ezahlukeneyo: Ifanelekile emanzini, emoyeni, kwioyile, kwizinto ezingonakalisiyo, nakwizinto ezidityanisiweyo (ezinemigqumo enganyangekiyo).
5. Iinkcukacha zobugcisa
Uvavanyo loxinzelelo: Uxinzelelo oluqhelekileyo luphantsi ukuya koluphakathi (umz., i-PN6–I-PN16 / Iklasi ye-125–Iklasi 150).
Uluhlu lobushushu:
Ii-elastomers eziqhelekileyo (umz., i-NR, i-EPDM): -10°C ukuya kwi-90°C (14)°F ukuya kwi-194°F).
Izitywino zobushushu obuphezulu (umz., iViton®, iPTFE): -20°C ukuya kwi-150°C (-4)°F ukuya kwi-302°F).
Ukuthobela iMigangatho:
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
Iivalvu zebhabhathane eziqinileyo ezitywiniweyo ezithambileyo D341X-16Qzisetyenziswa kakhulu kwezi:
Ubonelelo lwaManzi kunye nokuHanjiswa kwamanzi: Iinkqubo zamanzi zikamasipala, amaziko okunyanga amdaka, kunye neenethiwekhi zokunkcenkceshela.
Iinkqubo ze-HVAC: Ulawulo lomoya, amanzi, okanye umphunga ekufudumaleni, ekuphefumleni, nakwi-air conditioner.
Ishishini Lokutya Neziselo: Usetyenziso lwezempilo olunezitywino ezihambelana ne-FDA (umz., i-EPDM enezigqubuthelo zomgangatho wokutya).
Iinkqubo zeMizi-mveliso Jikelele: Ukuphathwa kolwelo olungaboliyo kwiimveliso zeekhemikhali, zephepha, kunye nezamayeza (kwiindawo ezithambileyo kuphela).
Ukwakha iinqanawa zaselwandle: Ulawulo lokuvula/ukucima amanzi olwandle okanye iinkqubo ze-ballast (ezinezixhobo ezimelana nokugqwala).
7. Imida kunye nezinto eziqwalaselwayo
Imida yoXinzelelo kunye noBushushu: Ayifanelekanga kwiindawo ezinoxinzelelo oluphezulu (umz., >PN16) okanye kwiindawo ezinobushushu obugqithisileyo (umz., umphunga ongaphezulu kwe-150).°C).
Iingozi Zokugqwala: Izixhobo zesinyithi (umz., imizimba yesinyithi esityhidiweyo) zinokugqwala kwiindawo ezinoburhalarhume; ziphuculwe zibe yintsimbi engagqwaliyo okanye izinto ezigqunywe ngepeyinti kwiimeko ezinzima.
I-Abrasive Media: Iiseal ezithambileyo zinokuguga ngokukhawuleza xa zinolwelo oluneziqwenga; cinga ngeevalvu zebhabhathane eziqinileyo okanye ezinye izinto zokukhusela.
Ukukhethwa kwe-Actuator: Kwiivalvu ezinkulu okanye xa usebenza rhoqo, sebenzisa ii-actuator ze-pneumatic/hydraulic ukuze uphephe ukudinwa ngesandla.
8. Ukufakelwa kunye nokugcinwa
Ufakelo:
Qinisekisa ukuba iiflange zilungelelanisiwe kwaye iibholithi ziqiniswe ngokulinganayo ukuthintela ukuvuza.
Kuphephe ukufaka ivalvu phantsi koxinzelelo olukhulu lombhobho.
Ulondolozo:
Hlola rhoqo isitywino ukuba asigugi okanye siyaqhekeka, ingakumbi xa sisetyenziswa kakhulu.
Thambisa isiqu kunye ne-actuator rhoqo ukuqinisekisa ukusebenza kakuhle.
Buyisela isitywino ukuba kukho ukuvuza; ezinye iindlela zoyilo zivumela ukutshintshwa kwesitywino ngaphandle kokususa ivalvu kumbhobho.
