Butterfly mavharuvhu zvinhu zvakakosha zvekudzora kuyerera kwepombi mumaindasitiri akasiyana.Pakati pemhando dzakasiyana-siyana dziripo, mavharuvhu e butterfly uye flange uye mavharuvhu e butterfly ma-single-flange anomira pachena nekuda kwemaitiro awo akasiyana uye mashandisirwo.Mukuongorora uku kwekuenzanisa, tichaongorora dhizaini, mashandiro, zvakanakira, uye zvipimo zvemhando nhatu idzi kuti tinzwisise kukodzera kwavo mumamiriro akasiyana.
POSHI.Nhanganyaya
1. Chii chinonzi wafer butterfly valve
Wafer Butterfly Valve: Iri rudzi rwevharuvhu rakagadzirirwa kuiswa pakati pemapipe maviri epombi, kazhinji kacho chidimbu.Iine slim profile ine valve plate inotenderera pane shaft kudzora kuyerera.
Zvakanakira zvewafer butterfly valve:
· The wafer-type butterfly valve ine hurefu hwechimiro chechimiro, zvinoreva kuti chimiro chakatetepa, chinoita kuti chive chakakodzera zvikuru kune nzvimbo dzine nzvimbo shoma.
· Ivo vanopa maviri-nzira, kuvharika kwakasimba uye akakodzera masisitimu ane yakaderera kusvika yepakati kudzvanywa zvinodiwa.
· Mukana mukuru wewafer butterfly valve ndeye compact dhizaini.

2. Chii chinonzi flange butterfly valve
Flange butterfly valve: The flange butterfly valve ine integral flanges kumativi ese uye inogona kuvharirwa zvakananga pakati pemaflange ari mupombi.Zvichienzaniswa nepinch mavharuvhu, vane refu kuvaka kureba.
Zvakanakira zveflange butterfly valve:
• The flange butterfly vharuvhu ine flange kumagumo iyo yakananga bhaudhi kune pombi flange.Iyi dhizaini inowedzera kusimba uye kugadzikana, ichiita kuti ive yakakodzera kune yakakwira-voltage maapplication uko kwakachengeteka kubatana kwakakosha.
· Flange butterfly mavharuvhu zvakare zvakareruka kuisa uye disassemble, nokudaro kurerutsa kugadzirisa uye kuchengetedza mari.
· Iyo flange butterfly valve inogona kuiswa kumagumo epombi uye kushandiswa sevhavha yekugumisa.

3.Chii chinonzi flange butterfly valve
Chimiro cheimwe flange butterfly valvendeyekuti kune imwe flange mukati me longitudinal yepakati yevhavha yemuviri, iyo inoda kugadziriswa pane flange yepombi ine mabhoti marefu.
Zvakanakira zveimwe flange butterfly valve:
· Iine hurefu hwechimiro chevhavhavhavhavha yeshavishavi uye inogara munzvimbo diki.
· Hunhu hwakasimba hwekubatanidza hwakafanana nehwemavharuvhu e butterfly.
· Inokodzera yepakati uye yakaderera pressure system.
PIRI.musiyano
1. Mitemo yekubatanidza:
a) Wafer butterfly valve: Iri vharuvhu rinowanzoita-multi-connection standard uye rinogona kuenderana neDIN PN6/PN10/PN16, ASME CL150, JIS 5K/10K, nezvimwe.
b) Flange butterfly vharafu: kazhinji chiyero chimwe chete chekubatanidza.Shandisa chete anowirirana akajairwa flange kubatana.
c) Single flange butterfly valve: kazhinji zvakare ine imwechete yakajairwa yekubatanidza.
2. Saizi yemhando
a) Wafer butterfly valve: DN15-DN2000.
b) Flange butterfly valve: DN40-DN3000.
c) Single flange butterfly valve: DN700-DN1000.
3. Kuiswa:
a) Kuiswa kwewafer butterfly valves:
Kuiswa kuri nyore sezvo vachigona kuiswa pakati pemaflange maviri vachishandisa 4 marefu mabhaudhi.Mabhoti anopfuura nepakati peflange uye muviri wevharuvhu, iyi setup inobvumira kukurumidza kuisirwa uye kubviswa.
b) Kuisa flange butterfly valve:
Sezvo kune akakosha maflange pamativi ese, mavharuvhu eflange akakura uye anoda imwe nzvimbo.Izvo zvinogadziriswa zvakananga kune pombi flange ine short studs.
c) Kuiswa kweimwe flange butterfly valve:
inoda mabhaudhi akareba ane misoro miviri akaiswa pakati pemafurange maviri epombi.Nhamba yemabhoti inodiwa inoratidzwa mutafura iri pasi apa.

4. Mutengo:
a) Wafer butterfly valve: Kana ichienzaniswa nemavharuvhu eflange, mavharuvhu ewafer anowanzo kudhura zvakanyanya.Kureba kwavo kupfupi kwekuvaka kunoda zvinhu zvishoma uye kunongoda mabhaudhi mana chete, nekudaro kudzikisa mutengo wekugadzira nekuisa.
b) Flange Butterfly Valve: Mavharuvhu eFlange anowanzo kudhura zvakanyanya nekuda kwekuvakwa kwavo kwakasimba uye yakakosha flange.Mabhaudhi uye kuisirwa kunodiwa kune flange kubatana kunoguma nemutengo wakakwira.
c) Single flange butterfly valve:
