Kunezinhlobo eziningi zamavalvu ovemvane, futhi ziningi izindlela zokuhlukanisa.
1. Ukuhlukaniswa ngesakhiwo
(1)i-valve ye-butterfly egxilile;(2) i-valve uvemvane ene-eccentric eyodwa;(3) kabili-I-valve ye-butterfly eccentric;(4) i-valve uvemvane ene-eccentric emithathu
2. Ukuhlukaniswa ngokwezinto ezibonakalayo ezingaphezulu
(1) Ivalve uvemvane eqinile
(2) Ivalve uvemvane evalwe ngokuqinile yohlobo lwensimbi.Ipheya yokuvala yakhiwe ngezinto eziqinile zensimbi ukuya ezintweni eziqinile zensimbi.
3. Ukuhlukaniswa ngefomu elivaliwe
(1) Ivalve uvemvane evalwe ngenkani.
(2) Ivalve uvemvane evala umfutho.Ingcindezi yophawu ikhiqizwa into enwebekayo yokuvala esihlalweni noma epuleti.
(3) Ivalve uvemvane evalwe ngokuzenzakalela.Umfutho othize we-seal ukhiqizwa ngokuzenzakalelayo ukucindezela okuphakathi.
4. Ukuhlukaniswa ngengcindezi yomsebenzi
(1) I-vacuum butterfly valve.I-valve ye-butterfly enengcindezi yokusebenza ephansi kunomoya ojwayelekile.
(2) I-valve uvemvane enengcindezi ephansi.I-Butterfly valve enengcindezi encane ye-PN≤1.6MPa.
(3) Ivalve uvemvane enengcindezi emaphakathi.Ingcindezi ebizwa ngokuthi i-PN iyivalve uvemvane engu-2.5∽6.4MPa.
(4) I-valve uvemvane enengcindezi ephezulu.Ingcindezi ebizwa ngokuthi i-PN iyivalve uvemvane engu-10.0∽80.OMpa.
(5) Ivalve uvemvane enengcindezi ephezulu kakhulu.I-valve yovemvane enengcindezi yegama elithi PN <100MPa.
5. Ukuhlukaniswa ngemodi yokuxhuma
(1)I-valve ye-butterfly ye-wafer
(2) I-valve uvemvane lwe-Flange
(3) Ivalve uvemvane
(4) Ivalve uvemvane eshiselwe
I-valve ye-Butterfly e-Concentric iwuhlobo lwe-valve evula iphinde ivalwe ngepuleti uvemvane eliyindilinga bese ivula, ivale futhi ilungise umzila woketshezi ngokuzungeza kwesiqu se-valve.Ipuleti butterfly valve uvemvane ifakwe isiqondiso ububanzi ipayipi.Kusiteshi esiyisilinda somzimba wevalve uvemvane, ipuleti uvemvane lediski lizungeza i-axis, futhi i-Angle yokuzungeza iphakathi kuka-0 no-90. Uma ukujikeleza kufinyelela ku-90, i-valve ivuleka ngokugcwele.
Amaphuzu abalulekile okwakhiwa nokufakwa
I-1) Indawo yokufaka, ubude, isiqondiso sokungenisa kanye nokuthekelisa kumele sihlangabezane nezidingo zedizayini, futhi ukuxhumana kufanele kuqine futhi kuqine.
2) Isibambo sazo zonke izinhlobo zamavalvu enziwe ngesandla afakwe epayipini lokufakwa kwe-thermal akumele siye phansi.
3) Ivalvu kufanele ihlolwe ngaphandle ngaphambi kokufakwa, futhi i-nameplate yevalvu izohlangabezana nezinhlinzeko zendinganiso kazwelonke yamanje ethi “General Valve Mark” GB 12220. Kumavalvu anomfutho wokusebenza omkhulu kuno-1.0 MPa futhi anqanyulwe ku-main. ipayipi, amandla kanye nokuhlolwa kokusebenza okuqinile kuyokwenziwa ngaphambi kokufakwa futhi kuyosetshenziswa ngemva kokufaneleka.Ekuhlolweni kwamandla, ukucindezela kokuhlola izikhathi ezingu-1.5 zokucindezela okulinganiselwe, futhi ubude besikhathi abukho ngaphansi kuka-5min.Igobolondo le-valve nokupakisha kufanele kuqeqeshwe ngaphandle kokuvuza.Ngokuhlolwa kokuqina, ingcindezi yokuhlola izikhathi eziyi-1.1 zokucindezela okuzisholo;ingcindezi yokuhlola izohlangabezana nezinga le-GB 50243 ngesikhathi sokuhlolwa, futhi i-valve seal surface ifanelekile.
Ukukhethwa komkhiqizo amaphuzu abalulekile
1. Imingcele yokulawula eyinhloko yevalve uvemvane yizicaciso nobukhulu.
2. I-valve ye-butterfly iyi-valve yomoya yepuleti elilodwa, isakhiwo sayo esilula, ukucubungula okulula, izindleko eziphansi, ukusebenza okulula, kodwa ukunemba kokulungiswa kumpofu, kuphela kulungele umoya wokungenisa umoya kanye nesistimu ye-air conditioning yokushintsha noma ukulungiswa okuqinile kwesenzakalo.
3. Kungaba ukusebenza kohlobo lwemanuwali, ugesi noma uziphu, kungalungiswa kunoma iyiphi i-Engeli yobubanzi obungama-90.
4. Ngenxa yepuleti eyodwa ye-valve ye-axial eyodwa, amandla okuthwala alinganiselwe, esimweni somehluko omkhulu wengcindezi, izinga lokugeleza elikhulu lapho impilo yesevisi ye-valve imfushane.I-valve inohlobo oluvaliwe kanye nohlobo olujwayelekile, ukufakwa kwe-insulation kanye nokungagqugquzeli.
5. I-valve ye-butterfly kagesi inokulawula izinhlobo ezimbili kuphela, i-actuator kagesi iyafana nevalve enamaqabunga amaningi.
