Ukulinganisa ngokunembileivalvu yebhabhathaneUsayizi ubalulekile ukuqinisekisa ukuthi ilingana kahle futhi ivimbele ukuvuza. Ngoba amavalvu e-butterfly adlala indima ebalulekile ezimbonini ezahlukahlukene. Kubandakanya uwoyela negesi, izitshalo zamakhemikhali kanye nezinhlelo zokulawula ukugeleza kwamanzi. Lawa mavalvu e-butterfly aphatha izinga lokugeleza koketshezi, ingcindezi, imishini ehlukene futhi alawula ukugeleza komfula.
Ukwazi ukukala usayizi wevalvu yebhabhathane kungavimbela ukungasebenzi kahle kokusebenza kanye namaphutha abizayo.
1. Izisekelo zamavalvu ebhabhathane
1.1 Iyini ivalvu yebhabhathane? Isebenza kanjani ivalvu yebhabhathane?
Amavalvu ebhabhathanelawula ukuhamba koketshezi ngaphakathi kwepayipi. I-valve yebhabhathane inediski ejikelezayo evumela uketshezi ukuthi ludlule lapho idiski ijika ihambisana nesiqondiso sokugeleza. Ukuguqula idiski iqonde ngqo esiqondisweni sokugeleza kumisa ukugeleza.
1.2 Izinhlelo zokusebenza ezivamile
Ama-valve e-Butterfly asetshenziswa ezimbonini ezahlukahlukene, okuhlanganisa uwoyela negesi, izitshalo zamakhemikhali kanye nezinhlelo zokulawula ukugeleza kwamanzi. Aphatha izinga lokugeleza, ahlukanise imishini futhi alawule ukugeleza kwamanzi. Ukuguquguquka kwawo kuwenza afanelekele izinsizakalo eziphakathi nendawo, eziphansi, eziphakeme kanye nengcindezi.
2. Uyilinganisa Kanjani I-Butterfly Valve?
2.1 Usayizi wobuso nobuso
Usayizi wobuso nobuso ubhekisela ebangeni eliphakathi kobuso obubili bevalvu yebhabhathane uma ifakwa epayipini, okungukuthi, isikhala esiphakathi kwezingxenye ezimbili zeflange. Lokhu kulinganisa kuqinisekisa ukuthi ivalvu yebhabhathane ifakwe kahle ohlelweni lwepayipi. Ubukhulu obunembile bobuso nobuso bungagcina ubuqotho bohlelo futhi buvimbele ukuvuza. Ngokuphambene nalokho, ubukhulu obungalungile bungaholela ezingozini zokuphepha.
Cishe zonke izindinganiso zichaza ubukhulu bobuso nobuso bama-valve e-butterfly. Esetshenziswa kabanzi yi-ASME B16.10, echaza ubukhulu bezinhlobo ezahlukene zama-valve e-butterfly, kufaka phakathi ama-valve e-butterfly. Ukunamathela kulezi zindinganiso kuqinisekisa ukuhambisana nezinye izingxenye ohlelweni lwamakhasimende olukhona.
2.2 Isilinganiso sokucindezela
Isilinganiso sokucindezela sevalvu yebhabhathane sibonisa ingcindezi ephezulu kakhulu ivalvu yebhabhathane engamelana nayo ngenkathi isebenza ngokuphepha. Uma isilinganiso sokucindezela singalungile, ivalvu yebhabhathane enengcindezi ephansi ingase yehluleke ngaphansi kwezimo zokucindezela okuphezulu, okuholela ekwehlulekeni kohlelo noma ngisho nasezingozini zokuphepha.
Amavalvu e-Butterfly atholakala ngezilinganiso ezahlukene zokucindezela, ngokuvamile asukela ku-Class 150 kuya ku-Class 600 (150lb-600lb) ngokwezindinganiso ze-ASME. Amanye amavalvu e-butterfly akhethekile angamelana nokucindezela kwe-PN800 noma ngaphezulu. Khetha ukucindezela kwesistimu ngokusekelwe ezidingweni zohlelo lokusebenza. Ukukhetha isilinganiso sokucindezela esifanele kuqinisekisa ukusebenza okuhle kakhulu kanye nokuphila kwenkonzo yevalvu ye-butterfly.
3. Ububanzi obujwayelekile be-valve yebhabhathane (DN)
Ububanzi obujwayelekile bevalvu yebhabhathane buhambisana nobubanzi bepayipi elixhumayo. Ubukhulu bevalvu yebhabhathane obunembile bubalulekile ekunciphiseni ukulahlekelwa yingcindezi kanye nokusebenza kahle kwesistimu. Ivalvu yebhabhathane engalingani kahle ingabangela ukuvinjelwa kokugeleza noma ukwehla kwengcindezi ngokweqile, okuthinta ukusebenza kwesistimu yonke.
Izindinganiso ezifana ne-ASME B16.34 zinikeza isiqondiso sosayizi wamavalvu ebhabhathane, okuqinisekisa ukuvumelana nokuhambisana phakathi kwezingxenye ngaphakathi kohlelo. Lezi zindinganiso zisiza ekukhetheni usayizi wamavalvu ebhabhathane ofanele wohlelo oluthile.
4. Ukulinganisa Usayizi Wesihlalo
Iisihlalo sevalvu yebhabhathaneUsayizi unquma ukulingana okufanele kanye nokusebenza kwevalvu yebhabhathane. Ukulinganisa okunembile kuqinisekisa ukuthi isihlalo silingana nomzimba wevalvu. Lokhu kulingana kuvimbela ukuvuza futhi kugcina ubuqotho bohlelo.
4.1 Inqubo Yokulinganisa
4.1.1. Kala ububanzi bembobo yokufaka (HS): Faka i-caliper emgodini bese ulinganisa ububanzi ngokunembile.
4.1.2. Nquma ukuphakama kwesihlalo (TH): Beka itheyipu yokulinganisa phansi kwesihlalo. Kala ngokuqondile uye onqenqemeni oluphezulu.
4.1.3. Kala ubukhulu besihlalo (CS): Sebenzisa i-caliper ukukala ubukhulu besendlalelo esisodwa esizungeze umphetho wesihlalo.
4.1.4. Kala ububanzi bangaphakathi (ID) besihlalo sevalvu: Bamba i-micrometer emgqeni ophakathi wesihlalo sevalvu yevelufa.
4.1.5. Nquma ububanzi bangaphandle (OD) besihlalo sevalvu: Beka i-caliper onqenqemeni lwangaphandle lwesihlalo sevalvu. Yelule ukuze ulinganise ububanzi bangaphandle.
5. Ukuhlukaniswa okuningiliziwe kobukhulu bevalvu yebhabhathane
5.1 Ukuphakama kwevalvu yebhabhathane A
Ukuze ulinganise ukuphakama A, beka i-caliper noma i-tape measure ekuqaleni kwesivalo sokugcina se-valve ye-butterfly bese ulinganisa phezulu kwesiqu se-valve. Qiniseka ukuthi isilinganiso simboza ubude bonke kusukela ekuqaleni komzimba we-valve kuze kube sekupheleni kwesiqu se-valve. Lokhu bukhulu kubalulekile ekunqumeni usayizi ophelele we-valve ye-butterfly futhi kunikeza nenkomba yokuthi ungagcina kanjani isikhala se-valve ye-butterfly ohlelweni.
5.2 Ububanzi bepuleti levalvu B
Ukuze ulinganise ububanzi bepuleti levalvu B, sebenzisa i-caliper ukukala ibanga ukusuka emaphethelweni epuleti levalvu, unake ukudlula phakathi kwepuleti levalvu. Incane kakhulu izovuza, inkulu kakhulu izokwandisa i-torque.
5.3 Ubukhulu bomzimba we-valve C
Ukuze ulinganise ubukhulu bomzimba wevalvu u-C, sebenzisa i-caliper ukukala ibanga emzimbeni wevalvu. Ukulinganisa okunembile kuqinisekisa ukulingana nokusebenza okufanele ohlelweni lwamapayipi.
5.5 Ubude Bezihluthulelo F
Beka i-caliper eceleni kobude besihluthulelo ukuze ulinganise ubude buka-F. Lokhu bukhulu bubalulekile ukuqinisekisa ukuthi isihluthulelo sifanelana kahle ne-actuator ye-butterfly valve.
5.5 Ububanzi besiqu (Ubude Ohlangothini) H
Sebenzisa i-caliper ukuze ulinganise ngokunembile ububanzi besiqu. Lokhu kulinganisa kubalulekile ukuqinisekisa ukuthi isiqu singena kahle ngaphakathi kwenhlangano yevalvu yebhabhathane.
5.6 Usayizi Wembobo J
Kala ubude buka-J ngokubeka i-caliper ngaphakathi kwembobo bese uyinweba iye kolunye uhlangothi. Ukukala ubude buka-J ngokunembile kuqinisekisa ukuhambisana nezinye izingxenye.
5.7 Usayizi Wentambo K
Ukuze ulinganise u-K, sebenzisa igeyiji yentambo ukuze uthole usayizi oqondile wentambo. Ukulinganisa u-K ngendlela efanele kuqinisekisa ukufakwa kwentambo ngendlela efanele kanye nokuxhumeka okuphephile.
5.8 Inani Lemigodi L
Bala inani eliphelele lemigodi eflengeni yevalvu yebhabhathane. Lokhu bukhulu bubalulekile ukuqinisekisa ukuthi ivalvu yebhabhathane ingaboshwa ngokuphephile ohlelweni lwamapayipi.
5.9 Isikhungo Sokulawula Ibanga le-PCD
I-PCD imele ububanzi obuvela enkabeni yembobo yokuxhuma phakathi nendawo yepuleti yevalvu kuya emgodini ovundlile. Beka i-caliper maphakathi nembobo ye-lug bese uyinweba phakathi nendawo yembobo ovundlile ukuze ulinganise. Ukulinganisa ngokunembile i-P kuqinisekisa ukuhambisana kahle nokufakwa ohlelweni.
6. Amathiphu Awusizo Nokucatshangelwa
6.1. Ukulinganiswa kwamathuluzi okungalungile: Qiniseka ukuthi wonke amathuluzi okulinganisa alinganiswe kahle. Amathuluzi angalungile angabangela ukulinganiswa okungalungile.
6.2. Ukungahambisani kahle ngesikhathi sokulinganisa: Ukungahambisani kahle kungaholela ekufundweni okunephutha.
6.3. Ukunganaki imiphumela yokushisa: Cabanga ngokushintsha kwezinga lokushisa. Izingxenye zensimbi nerabha zingakhula noma zinciphe, kuthinte imiphumela yokulinganisa.
Ukulinganisa ngokunembile izihlalo zamavalvu ebhabhathane kudinga ukunaka imininingwane nokusebenzisa amathuluzi afanele. Ukulandela lezi zinyathelo kuqinisekisa ukuthi ivalvu yebhabhathane ifakwe kahle futhi isebenza kahle ngaphakathi kohlelo.
7. Isiphetho
Ukulinganisa ngokunembile ubukhulu bevalvu yebhabhathane kuqinisekisa ukusebenza kahle kanye nobuqotho bohlelo. Sebenzisa amathuluzi alinganisiwe ukuze ulinganise ngokunembile. Qondanisa amathuluzi kahle ukuze ugweme amaphutha. Cabanga ngemiphumela yokushisa ezingxenyeni zensimbi. Funa iseluleko sochwepheshe uma kudingeka. Ukulinganisa ngokunembile kuvimbela izinkinga zokusebenza futhi kuthuthukise ukusebenza kahle kohlelo.
