Sevhavha inoshandiswa zvakanyanya, iyobhora vharafuzvakare ndiyo yakanyanya mhando yevharuvhu.Mhando dzakasiyana-siyana dzinosangana nekushandiswa kwemushandisi mune dzakasiyana nguva dzepakati, dzakasiyana tembiricha nharaunda uye dzakasiyana siyana zvinodiwa mukuita chaiko.Izvi zvinotevera zvinounza maitiro ezvizhinji zvemavharuvhu ebhora anoyangarara, mavharuvhu ebhora akamiswa, eccentric half ball valves, V-shaped ball valves uye fluorine-lined ball valves.
Zvinoenderana nechimiro uye basa, inogona kukamurwa kuita:
1. Kune marudzi akawanda emavharuvhu ebhora.Chii zvachomavharuvhu ebhora anoyangarara: Mavharuvhu ebhora anoyangarara anoshandiswa sezvisimbiso uye bhora rinoyangarara.Inoshandisa kudzvanywa kwepakati kusundira bhora kuti rifambe chinhambwe uye kusvina chigaro chevharuvhu kuti chizadzise chisimbiso.Rudzi urwu rwevharuvhu inoyangarara inodzivirira kuvhura yakakura uye inokodzera mapaipi nemidziyo ine caliber yeDN "200 uye kudzvanywa kwePN "100.Kana iyo dhayamita yebhora yakakura kwazvo, inokotama muviri wevhavha uye inokundikana pasi pekumanikidzwa kwepakati;kana kudzvinyirirwa kwakanyanyisa, vheji yebhora ichasvinwa uye elastically uye chigaro chevhavha chinoputika chichave chakaremara zvachose, chinogona kukuvadza chisimbiso uye chinokanganisa valve yebhora.hupenyu.
2. Ivhavha yebhora yakagadziriswa inogadziriswa nepamusoro uye pasi pasi.Chigaro chevharuvhu chine chitubu chemashizha kana cylindrical spiral spring.Kana yakashongedzerwa, chitubu chechigaro chevharuvhu chinomanikidzwa kuburitsa simba rekutanga-kusimbisa kuti riwane chisimbiso chekutanga chevhavha, uye kudzvanywa kunosundirwa panguva yekushandiswa.Chigaro chevharuvhu chinoenda kubhora kuti chiwane chisimbiso.Nekuti bhora harifambi, rinodaidzwa kunzi fixed ball valve.Rudzi urwu rwekugadzirisa runovimbika kupfuura mavharuvhu ebhora anoyangarara nekuda kwekuvimbika kwayo.Inogona kushandiswa muhupamhi hwakawanda, kwete chete kune yakaderera-kudzvinyirira madhayamita madiki, asiwo nepamusoro-kumanikidza madhayamita makuru.Asi chimiro chayo chakaoma zvikuru
, Mutengo wemutengo wakakwirira, pakusarudza, unofanira kusarudza maererano nezvinodiwa chaizvo.
3. Eccentric hemispherical valve.Iri rudzi rwevharuvhu yebhora rinotora eccentric chimiro.Chimiro chechimiro chakafanana neicho cheakawanda-layer katatu eccentric yakaoma-yakavharwa butterfly valve.Chigaro chevharuvhu uye bhora hazvina kupfeka uye zvine basa rekuvhara rakasimba.Bhora ingori 1/4 chete yevhavhavha yebhora.Iine nzvimbo yakakomberedzwa, huremu hwakareruka uye mutengo wakaderera.Izvi zvine simba rekugera uye rinogona kushandiswa mupombi yepakati ine tambo refu isina jamming.
4. Iyo flange ye thermal insulation ball valve ndeye imwe kusvika kune mbiri yakatarwa yakakura kupfuura general flange ball valve.Inotora muviri wakakosha wevharuvhu uye dhizaini-yakaiswa bhora dhizaini.Bhachi resimbi rinosungirirwa pakati pemafurange akakura ari kunze kwemuviri wevharuvhu.Inonziwo jacketed ball valve.Jacketed interfaces inoiswa pamativi ese emuviri wevharuvhu, iyo inogona kunyungudutswa nemhepo kana imwe gasi rinopisa kudzivirira iyo yepakati kubva mukudonhedza kana crystallization pakamuri tembiricha.Thermal insulation bhora mavharuvhu anonyanya kushandiswa mapaipi uye midziyo iri nyore crystallize uye inoda kupisa kupisa mupetroleum, makemikari, metallurgical, uye mishonga masisitimu.
5. Iyo V-yakaita sevhavha yebhora ivharuvhu yebhora inodzora.Gomba rekuyerera kwebhora rakasiyana zvakanyanya kubva kune rakatwasuka nemuburi revharuvhu yebhora.Bhora rine chimiro chakaita V uye rinowanzotora chigadziro chakagadzika chine madzinde maviri epamusoro uye epasi.
6. Fluorine-lined bhora vharafu inowanzoshandiswa mu yakaderera tembiricha uye yakasimba inoodza svikiro midziyo mapaipi.Iri rudzi rwevharuvhu yebhora yakamisikidzwa nemapurasitiki asingadziviriri einjiniya akadai sePFA kana FEP munzvimbo dzese dzenzira inoyerera inosangana nepakati.Inogona kutsiva inodhura Stainless simbi uye Hastelloy pasi pemamiriro ekusapfuudza tembiricha yebasa refluorine rabha mupombi yakaderera yekumanikidza., Monel alloy, Nha.
