Kunemihlobo eminengi yamavalvu we-butterfly, begodu kuneendlela ezinengi zokuhlukanisa.
1. Ukuhlukaniswa ngefomu lesakhiwo
(1)ivalvu ye-butterfly ehlanganisiweko; (2) ivalvu yevivane ene-excentric eyodwa; (3) kabili-ivalvu yevithamini engakajayeleki; (4) ivalvu yevithamini enama-3-excentric
2. Ukuhlukaniswa ngokuya ngepahla yokuvala
(1) Ivalvu yevithamini eqinileko
(2) Ivalvu yevemvane evalwe qinileko enomhlobo wensimbi. I-pair yokuvala yakhiwe ngezinto eziqinileko zensimbi ukuya kwezinto eziqinileko zensimbi.
3. Ukuhlukaniswa ngefomu elivaliweko
(1) Ivalvu yevivane evaliwe ngokugandeleleka.
(2) Ivalvu yevithamini yokuvala ngokugandeleleka. Umfutho wokuvala wenziwa yinto yokuvala ye-elastic esihlalweni nofana epuletini.
(3) Ivalvu yevivane evaliweko ezenzakalelayo. Umfutho othileko wokuvala wenziwa ngokuzenzakalelayo mfutho ophakathi.
4. Ukuhlukaniswa ngokugandeleleka komsebenzi
(1) I-vacuum butterfly valve. Ivalvu ye-butterfly enomfutho wokusebenza ongaphasi kwe-atmosphere ejwayelekileko.
(2) Ivalvu yevithamini enomtjhini ophasi. Ivalvu ye-Butterfly enomfutho omncani we-PN≤1.6MPa.
(3) Ivalvu yevithamini enomfutho ophakathi. Umfutho we-PN yi-valve ye-butterfly ye-2.5∽6.4MPa.
(4) Ivalvu yevithamini enegandelelo eliphezulu. I-nominal pressure PN yi-butterfly valve ye-10.0∽80.OMPa.
(5) Ivalvu yevithamini enegandelelo eliphezulu khulu. Ivalvu ye-Butterfly enomfutho omncani we-PN <100MPa.
5. Ukuhlukaniswa ngendlela yokuxhumana
(1)Ivalvu ye-wafer butterfly
(2) I-flange butterfly valve
(3) Ivalvu ye-lug butterfly
(4) Ivalvu ye-butterfly ehlanganisiweko
Ivalvu ye-Concentric Butterfly mhlobo we-valve evula begodu ivale ngepuleti ye-butterfly eyindilinga bese ivula, ivale begodu ilungise umsele we-fluid ngokujikeleza kwesiqu sevalvu. Ipuleti yevithamini yevalvu yevivane ifakwe ngendlela yobubanzi bephayiphu. Emseleni wesilinda womzimba wevalvu ye-butterfly, ipuleti ye-butterfly yediski ijikeleza i-eksisi, begodu i-Angle yokujikeleza iphakathi kuka-0 no-90. Lokha ukujikeleza nakufika ku-90, ivalvu ivulekile ngokupheleleko.
Amaphuzu aqakathekileko wokwakha nokufaka
1) Indawo yokufaka, ukuphakama, indlela yokungenisa nokuthumela ngaphandle kufanele ihlangabezane neemfuneko zokuklama, begodu ukuxhumana kufanele kube budisi begodu kuqinile.
2) Isibambo sayo yoke imihlobo yamavalvu afakwe epayipini lokuvikela ukutjhisa akukafaneli sibe phasi.
. Ekuhlolweni kwamandla, umfutho wokuhlolwa uphindwe ka-1.5 womfutho oqakathekileko, begodu isikhathi asikho ngaphasi kwemizuzu emi-5. Igobolondo levalvu nokupaka kufanele kube kuhle ngaphandle kokuvuza. Ukuhlolwa kokuqina, umfutho wokuhlolwa uphindwe ka-1.1 womfutho oqakathekileko; umfutho wokuhlolwa uzakuhlangabezana nezinga le-GB 50243 ngesikhathi sokuhlolwa, begodu indawo yokuvala ivalvu iyafaneleka.
Ukukhethwa komkhiqizo wamaphuzu aqakathekileko
1. Imingcele ekulu yokulawula yevalvu ye-butterfly ziimfanelo nobukhulu.
.
3. Kungenziwa ngezandla, ngegezi nofana nge-zipper, kungalungiswa nanyana ngiyiphi i-Angle yama-90.
4. Ngebanga lepuleti ye-valve eyodwa ye-axial, amandla wokuthwala alinganiselwe, ebujameni bomehluko omkhulu womfutho, izinga lokugeleza elikhulu lokha ipilo yesevisi yevalvu ifitjhani. Ivalvu inomhlobo ovaliweko nomhlobo ovamileko, ukuvikela nokungavikeleki.
5. Ivalvu ye-butterfly kagesi inokulawula okubili kwaphela, i-actuator kagesi iyafana nevalvu yamaqabunga amanengi.
