Zhongfa Valve inyanzvi yekugadzira zvikamu zvevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhuvhu,yakavambwa muna2006, ichipa mavharuvhu uye mavharuvhu ezvigadziro zvigadzirwa kunyika dzinopfuura makumi maviri pasirese.
A shavishavi vharafu rinoumbwa zvinotevera zvikamu, shavishavi zvikamu zita vari vharafu muviri, vharafu Disc, vharafu mugodhi, vharafu chigaro, chisimbiso pamusoro, uye oparesheni actuator, zvino, isu tichasuma izvi shavishavi vharafu zvikamu chimwe nechimwe.
# 1 Butterfly valve parts--Valve body
Isu tinokurukura muviri wevhavha maererano nekubatana uye zvinhu
1. Kazhinji kutaura, maererano nenzira dzakasiyana dzekubatanidza, mavharuvhu e butterfly ane rudzi rweflange, rudzi rwewafer, uye lug type, uye maitiro akaenzana anoratidzwa mumufananidzo.Kune yega yega yemhando yekubatanidza, kune misiyano yakavanzika zvinoenderana neakasiyana mold, senge yewafer butterfly valve, Zhongfa Valve ine anotevera akajairika mold.
2. Maererano nezvinyorwa, izvo zvakajairika ndeye ductile iron body, carbon steel body, Stainless steel body, brass body, uye super duplex simbi muviri.
#2Butterfly valve parts--Valve Disc
Chimiro chevhavha disc chinosiyanawo, pini disc, pinless disc, disc ine rubber, Disc neNylon, Electroplated Disc, uye zvichingodaro, Kazhinji, dhisiki yevhavha inosarudzwa maererano nemamiriro ekushanda uye nepakati.
Kune pinless disc, Pane kuburikidza neshaft uye kaviri hafu shaft, disc isina pini inoderedza njodzi yekudonha mikana, yeDisc ine pini, zvinogona kuti pini yakasakara kana kuita ngura mushure menguva refu, iyo midhiya kubva papini pane dhisiki iyo inodonha shaft gomba.Tinoda kusarudza pinless disc yemutengi wedu.
# 3 Butterfly valve parts--Valve Spindle
The butterfly vharafu spindle inonziwo hunde, inoshandiswa kutapurirana, yakabatana kune actuator kana mubato, zvinotevera zvakananga anotyaira vharafu ndiro kutenderera, kuitira kuwana shavishavi vharafu chinja kana kugadzirisa basa.
1. Kubva pane zvinyorwa: Chigadzirwa chepindle chinowanzogadzirwa nesimbi isina tsvina uye kabhoni simbi, uye code yayo ndeiyi: simbi isina tsvina (2cr13, 304, 316, 316L), carbon steel (35, 45, Q235).
2. Kubva pamaitiro: shavivhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavuru (kurudyi).
a: Panyaya yemutengo: kaviri hafu-shaft inodhura kupfuura kuburikidza-shaft.
b: Panyaya yekushandiswa: iyo kaviri hafu-shaft inogona kuita zvinopfuura DN300, uye kuburikidza-shaft inogona kuita DN800.
c: Zvishandiso zvakasiyana-siyana: kuburikidza-shaft fittings inogona kushandiswa pane akapiniwa butterfly mavharuvhu ane yakaderera zvimedu.Chete maviri semi-shaft butterfly mavharuvhu anogona kushandiswa, uye chiyero chakaraswa chakakwira.
d: Gungano: kuburikidza-shaft isina pini ndiyo nzira yekutanga mukugadzira, dhizaini yakapusa, dhizaini yekugadzirisa, kaviri hafu-shaft kunetsa kwekugadzira, kazhinji yakakamurwa kuita shaft yepamusoro, uye yakaderera shaft.
# 4 Butterfly valve parts--Valve Seat
Chigaro cherabha chevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharubharabha uye chigaro cherabha chakapfava, uye chigaro chevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha moo ndipoje?
Musiyano pakati pechigaro cherubha chakaoma-backed uye chigaro cherubha chakapfava chevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha,isingagoni kutsiviwa pachayo uye inoda flange inokosha nokuda butterfly valve. ;chigaro chakapfava-chinotsigirwa chinogadzirwa nemuenzaniso, chinogona kutsiviwa pachacho uye chinogona kushandiswa neflange isiri yakakosha kune butterfly valve.
Panyaya yehupenyu hwesevhisi yerubha, hupenyu hwesevhisi hwechigaro chakapfava chekumashure hwakareba kupfuura yechigaro chakaoma chekumashure, chinova chimiro chakakura chakafaranuka.Valve yenguva refu yekushanda process vharafu chigaro shaft kupera kupfeka.Valve seat shaft inopera kuvuza mushure meiyo yakaoma kumashure chigaro chemvura inoyerera yakananga kunze kweiyo valve body leakage phenomenon.Asi iyo yakapfava musana hairatidzike mumamiriro ezvinhu aya.
# 5 Butterfly valve parts--Kuisa chisimbiso pamusoro
pane chisimbiso chakapfava uye chisimbiso chakaoma,Sarudzo yezvinyoro zvekuisa chisimbiso zvinhu:
1, Rubha (kusanganisira butadiene rabha, EPDM rabha, zvichingodaro), inonyanya kushandiswa mumapaipi anodzvinyirira akaderera pamusoro pemafuta nemvura.
2, Purasitiki (PTFE, naironi, nezvimwewo), yakawanda yezvinosvibisa midhiya mupombi.
Maitiro ekushanda: kubata, turbo, magetsi, pneumatic, hydraulic
Kusarudzwa kwezvinhu zvakaoma seal:
1, Copper alloy (yepasi-kumanikidza mavharuvhu)
2、 Chrome Stainless simbi (yeyakajairwa yakakwirira uye yepakati kumanikidza mavharuvhu)
3、Stellite alloy (yepamusoro tembiricha uye yakakwirira-kudzvanywa mavharuvhu uye yakasimba corrosive mavharuvhu)
4, Nickel-based alloys (yekuora media)
# 6 Butterfly valve parts--Operation Actuator
Butterfly mavharuvhu anowanzo shandiswa mune zvinotevera, Hand Lever, Worm Gear, Pneumatic Actuator.
Mabatirwo emaoko anowanzo gadzirwa neakaomarara, akaiswa kemikari, uye akaiswa poda.Ruoko rweruvoko kazhinji rune mubato uye chinovharira chibatiso, Inokodzera DN40-DN250.
Iro giya rehonye rakakodzera mavharuvhu makuru eshavishavi.Iyo worm gearbox inowanzo shandisa hukuru kupfuura DN250, kuchine maviri-nhanho uye matatu-nhanho turbine mabhokisi.
Pneumatic actuators yakakamurwa kuita zvikamu zviviri, single-acting uye kaviri-acting pneumatic actuators.
Magetsi emagetsi anogona kukamurwa kuva akawanda-anotendeuka marudzi uye chikamu-chekutendeuka mhando.Multi-turn type inoshandura kupfuura 360 ° kuvhura nekuvhara vharuvhu ukuwo part-turn type inotenderera kazhinji 90° kuvhura zvizere nekuvhara vharuvhu.
