Knife gedhi vharafu inogona kukamurwa kuita mhando nhatu zvichienderana nekubatanidza nzira, butt yekubatanidza, flange yekubatanidza uye lug yekubatanidza.Zvinoenderana nehupamhi hwevhavha yegedhi rebanga, kumanikidzwa kunobva kuPN16-PN2., Mavharuvhu egedhi ebanga anonyanya kushandiswa pakugadzira mapepa, kemikari fiber, petrochemical, metallurgy, dope, magetsi, sewage treatment.Mumishonga uye mamwe mamiriro ekushanda, banga regedhi valve rinonyanya kuumbwa nemuviri wevhavha uye gedhi.Zvinhu zvemuviri wevharuvhu ndeye ductile iron, kabhoni simbi uye simbi isina tsvina, uye nzvimbo yekuvharisa inogadzirwa neakasikwa-resistant rubber, fluorine rabha, nitrile rabha, uye EPDM rabha.Uye kuiswa chisimbiso chesimbi, kubva pachimiro chechimiro, banga regedhi vharafu ine compact dhizaini, inotora nzvimbo shoma, uye inogona kunyatso tsigira kusimba kwepombi.
Knife Gate Valve inoshandiswa papombi yeindasitiri ye-on-off operation.Chimiro chemuviri uye chigaro chinobvisa kuvhara kuvharika kwekuyerera nezvidimbu zvakanaka.Pamusoro pezvo, beveled banga mupendero unobatsira .. gedhi rakacheka nepakati gobvu media zviri nyore.Zvinoenderana neakasiyana mamiriro ekushanda: isingasimuke tsinde banga regedhi vharafu, banga rewafer
vharafu yegedhi, yakavharidzirwa banga regedhi vharafu, pneumatic banga gedhi vharafu, yemagetsi banga regedhi vharafu, bhuku rebanga gedhi vharafu uye bevel
giya banga regedhi vharafu zvese zviripo.
Features:
1. Muviri:
a) Muviri wakabatanidzwa une yakazara bore chimiro unovimbisa kuyerera kwakatsetseka, kuungana kuri nyore uye kudiki kudonha kwegoko.
b) Dhizaini yedhizaini kuzasi kwechiteshi chegedhi, pachinzvimbo chegorofu, inobvisa chero ingangovharika kana vharafu yavharwa.
2. Gedhi:
a) Beveled banga mupendero inopa yakasimba yekucheka kushushikana uye kusungirira chisimbiso.
b) PTFE resilient point guide pamusoro pechiteshi inodzivirira simbi-simbi kusangana pakati pegedhi nemuviri.
c) Ukobvu hwegedhi hunogona kuwedzerwa kuti usangane nedzvinyiriro yepamusoro.
3. Chigaro:
a) Side-yekupinda chigaro chinotsiviwa, kuderedza mutengo wekugadzirisa.
b) Chigaro chakaremerwa chinogadziriswa kusangana nekirasi yekuisa chisimbiso uye kubhadhara zvakajairwa chigaro kupfeka.
4. Zvimwe:
a) Kusundirwa kaviri kunoderedza torque inodiwa pakushanda
Pane zvinhu zvitatu zviri pasi apa:
Pazasi pegedhi i-u-shaped blade inopinza, iyo inogona kukwenya inonamira panzvimbo yekuisa chisimbiso uye nekukurumidza kugura mvura.pakati
2. Nzvimbo yepamusoro yegedhi yakave yakanyatsogadziriswa uye yakasvibiswa, iyo isina kungoita chisimbiso chiri nani, asiwo inonyatsodzivirira hupenyu hwebasa rekutakura uye chigaro chevhavha.
3. Chivharo chegwaro pamutumbi wevhavha chinoita kuti gedhi rifambe zvakanaka, uye iyo extrusion block inova nechokwadi chekuisa chisimbiso chegedhi.
ZFA Valve inonyatso shandisa API598 yakajairwa, tinoita ese ari maviri ekumanikidza bvunzo kune ese vharafu 100%, inovimbisa kuendesa 100% mhando mavharuvhu kune vatengi vedu.
Muviri wevharuvhu unotora GB yakajairwa zvinhu, kune yakazara gumi neshanu maitiro kubva kusimbi kuenda kune valve muviri.
Kuongororwa kwemhando kubva pane isina chinhu kusvika kune yapera chigadzirwa ndeye 100% inovimbiswa.
ZFA Valve inotarisa pakugadzirwa kwemavharuvhu kwemakore gumi nematanhatu, nechikwata chehunyanzvi chekugadzira, tinogona kubatsira vatengi vedu kuchengetedza zvinangwa zvako nemhando yedu yakagadzikana.
