1. Ihlathululo eyisisekelo nesakhiwo
Ivalvu ye-butterfly ehlanganisiweko (eyaziwa nangokuthi "i-center-line butterfly valve") yi-quarter-turn rotary valve eyenzelwe ukuvula/ukuvala nofana ukukhandela ukulawula ukugeleza emapayipini. Iimpawu zayo eziqakathekileko zifaka hlangana:
Umklamo ohlanganisiweko: Isiqu sevalvu, idiski, nesihlalo zihlangene ku-eksisi efanako ephakathi, okwenza isakhiwo esilula nesincani.
Indlela yokuvala ngokuthambileko: Isivalo se-elastomeric esiguquguqukako (isib., iraba, i-EPDM, i-NBR) sihlanganiswe emzimbeni wevalvu nofana isihlalo, ukunikela ngokuvala okuqinileko ukukhandela ukuvuza.
Iiphetho ezinama-Flanged: Ivalvu ifakwe iinhlanganisela ezine-flanged, okwenza bona kube lula ukufakwa emapayipini ahambisana namazinga afana ne-ANSI, DIN, nofana i-JIS.
2.Iingcenye eziqakathekileko
3. Umthetho Wokusebenza
Indawo evulekileko: Idiski ijika 90° ukukhambelana nendlela yokugeleza, ukunciphisa ukwehla komfutho nokuvumela ukugeleza okuzeleko.
Indawo evaliweko: Idiski ijika emuva ukucindezela isivalo esithambileko, okwenza ukuvala okuqinileko. Umklamo ohlanganisiweko uthembele ekuguqukeni kwe-elastic kwesivalo ukufezekisa ukuvala, okwenza bona kube kuhle khulu ekusetjenzisweni okugandelelweko okuphasi.
4. Iimpawu eziqakathekileko neenzuzo
Ukuvala okuqinileko: Ukuvala okuthambileko kunikela ukujamelana nokuvuza okuhle khulu, kanengi kuhlangabezana namazinga wokuvala amabhamuza (isib., i-ANSI B16.104 Class VI, ISO 15848-1).
Ukusebenza nge-Torque ephasi: Umklamo ohlanganisiweko nokuvala okuguquguqukako kwehlisa ukutjhayisana, okwenza bona kube lula ukusebenza ngesandla nofana ukusetjenziswa ngama-actuators alula.
Incani begodu ilula: Nayiqathaniswa namavalvu we-gate nofana we-globe, amavalvu we-butterfly ahlanganisiweko mancani begodu kulula ukuwafaka eendaweni ezilinganiselweko.
Ibiza: Isakhiwo esilula nokusetjenziswa kwezinto ezincani kwenza bona zithengeke ngeendingo ezisisekelo zokulawula ukugeleza.
Ukuvumelana kweendaba ezihlukahlukeneko: Ilungele amanzi, umoya, amafutha, uketshezi olungaboli, kanye nemidiya enezinhlamvu (enezingubo ezijamelana nokuguga).
5. Iinqophiso zezobuchwepheshe
Izinga lokugandeleleka: Ngokuvamileko ukugandeleleka okuphasi ukuya phakathi (isib., PN6–PN16 / Iklasi 125–Iklasi 150).
Izinga lokutjhisa:
Ama-elastomers ajwayelekileko (isib., NR, EPDM): -10°C ukuya ku-90°C (14°F ukuya ku-194°F).
Iimvalo ezinezinga lokutjhisa eliphezulu (isib., i-Viton®, i-PTFE): -20°C ukuya ku-150°C (-4°F ukuya ku-302°F).
Ukuthobela amazinga:
Umklamo: EN593, API 609, MSS SP-67.
I-Flange: ANSI B16.5, ANSI B16.10 DIN EN 1092-1,
Ukuhlolwa: i-API 598, (ukuhlolwa kokuvuza).
6. Iinsetjenziswa
Ukuvala okuthambileko kwamavalvu we-butterfly concentric D341X-16Qzisetjenziswa khulu:
Ukunikelwa kwamanzi nokukhipha amanzi: Iinhlelo zamanzi zikamasipala, iindawo zokuhlanza indle, kanye namanethiwekhi wokuthelelela.
IinHlelo ze-HVAC: Ukulawula umoya, amanzi, nofana umtjhiso ekufuthumeleni, ekungeniseni umoya, kanye nokupholisa umoya.
Ibubulo lokudla neziselo: Iinsetjenziswa zokuhlanzeka ezinama-seal athobela i-FDA (isib., i-EPDM eneengubo ezisezingeni lokudla).
Iinqubo eziJayelekileko zezebubulo: Ukuphathwa kweengazi ezingaguliko emakhemikhali, amaphepha, kanye nemithi (yemidiya elula kwaphela).
Ukwakhiwa kwemikhumbi nemikhumbi: Ukulawula ukuvula/ukuvala emanzini welwandle nofana eenhlelweni ze-ballast (ngezinto ezijamelana nokugqwala).
7. Imikhawulo nokucabangela
Imikhawulo yokugandeleleka nokutjhisa: Akukafaneli ukugandeleleka okukhulu (isib., >PN16) nofana ukusetjenziswa kwamazinga womtjhiso aphezulu (isib., i-steam engaphezu kwe-150°C).
Iingozi zokugqwala: Iingcenye zensimbi (isib., imizimba yensimbi) ingagqwala eendaweni ezinolaka; uthuthukise ensimbini engagqwali nofana izinto ezigcotshiweko malungana nobujamo obubudisi.
Iinsetjenziswa ezirhurhulako: Iimvalo ezithambileko zingaguga msinyana ngezinto ezineenhlayiya; cabanga ngamavalvu we-butterfly aqinileko nofana ezinye iingubo zokuvikela.
Ukukhethwa kwe-Actuator: Emavalveni amakhulu nofana ukusebenza njalo, sebenzisa ama-actuator we-pneumatic/hydraulic ukubalekela ukudinwa ngezandla.
8. Ukufakwa nokugcina
Ukufakwa:
Qinisekisa bona amafletjhi ahlangene begodu amabhawudo aqiniswe ngokufanako ukukhandela ukuvuza.
Balekela ukufaka ivalvu ngaphasi kokugandeleleka okukhulu kwepayipi.
Ukutjheja:
Hlola njalo isivalo sokuthi sigugile namkha siqhekekile, khulukhulu eensetjenzisweni ezineemjikelezo eziphezulu.
Gcoba isiqu ne-actuator ngeenkhathi ezithileko ukuqinisekisa bona kusebenza kuhle.
Buyisela isivalo nangabe kuvuza; eminye imiklamo ivumela ukutjhugululwa kwesivalo ngaphandle kokususa ivalvu epayipini.
9. Amathiphu wokukhetha umthengisi nomkhiqizo
Isitifiketi sezinto: Qinisekisa bona ama-seal ahlangabezana namazinga webubulo (isib., i-FDA yokudla, i-ATEX yeendawo eziqhumako).
Iinkhetho zokwenza ngendlela oyifunako: Abanye abathengisi banikela ngemiklamo evikela umlilo, iimpawu eziphephileko emlilweni, nofana ukugcotshwa okukhethekileko (isib., i-epoxy, i-PTFE) malungana nokusetjenziswa okuhlukileko.
Isiphetho
Ukuvala okuthambileko kwamavalvu we-butterfly concentricyisisombululo esingabiziko, esithembekileko sokulawula ukugeleza komfutho ophansi ukuya phakathi eensetjenzisweni ezingakaqakatheki. Ubulula bazo, ukuvala okuqinileko, nokutlhogonyelwa lula kwenza bona zikhethwe khulu emanzini, i-HVAC, kanye neenhlelo zebubulo. Eendaweni ezitlhoga khulu, ukuthuthukisa ukuya emiklamweni engakajayeleki nofana izinto ezisezingeni eliphezulu kuyaphakanyiswa. Hlola ngaso soke isikhathi izakhiwo zemidiya, ubujamo bokusebenza, kanye neemfuneko zokulandela ukukhetha ivalvu efanele iindingo zakho.
Nanyana ngiyiphi iraba ehlezi ndawonyeivalvu yevivane, njenge-wafer butterfly valve, lug butterfly valveD7L1X-16Q, Y-strainer, i-wafer check valve,ivalvu yesangoZ41X-16Qiimfuno, ungathintana noIvalvu ye-TWSefektri, sizokuphendula ekuthomeni.
