Kusarudza vharafu yebhora kunoratidzika kunge kuri nyore kusvika waona zvese zvingasarudzwa. Sarudza iyo isiriyo, uye iwe unogona kutarisana neinodzivirirwa kuyerera, kutadza kutonga, kana kutadza system.

Mhando ina huru dzemavharuvhu ebhora dzakakamurwa nebasa nemagadzirirwo awo: vharafu yebhora inoyangarara, trunnion-yakaiswa bhora vharafu, yakazara-chiteshi vharafu, uye yakaderedzwa-chiteshi vharafu. Imwe neimwe inokodzera kudzvinyirira kwakasiyana uye kuyerera zvinodiwa.

Ndinogara ndichitaura naBudi, maneja wekutenga wemumwe wevatinoshanda navo muIndonesia, nezvekudzidzisa timu yake yekutengesa. Chimwe chezvipingamupinyi zvikuru kune vatengesi vatsva ndiyo yakasiyana-siyana yemavharuvhu. Ivo vanonzwisisa yakakosha pa/off basa, asi vobva varohwa nemashoko akadai “.trunnion^[1],” “L-port,” kana kuti “inoyangarara^[2].” Mutengi anogona kukumbira vheji yemutsara wepamusoro-soro, uye mutengesi mutsva anogona kupa vheji inoyangarara kana trunnion vharafu iri iyo inonyanya kudiwa Kuputsa zvikamu izvi zviri nyore, zvinonzwisisika ndezvekungotengesa chigadzirwa.

Ndeapi marudzi mana emavharuvhu ebhora?

Iwe unoda vharuvhu, asi iyo catalog inoratidza akawanda marudzi. Kushandisa iyo isiriyo kunogona kugadzira bhodhoro muhurongwa hwako kana kureva kuti uri kubhadharira zvakanyanya maficha ausingatomboda.

Mavharuvhu ebhora anowanzo kupatsanurwa nekugadzirwa kwavo kwebhora uye saizi yekubereka. Mhando ina dzakajairika ndeidzi: inoyangarara uye trunnion-yakaiswa (nerutsigiro rwebhora) uye yakazara-chiteshi uye yakaderedzwa-chiteshi (nekuvhura saizi). Imwe neimwe inopa chiyero chakasiyana chekuita uye mutengo.

Ngatitsemure izvi zviri nyore. Mhando mbiri dzekutanga dziri pamusoro pekuti bhora rinotsigirwa sei mukati mevhavha. Ainoyangarara bhora vharafu^[3]ndiyo yakajairika mhando; bhora rinobatwa panzvimbo nezvigaro zvezasi uye kumusoro kwerwizi. Yakanakira kune akawanda akajairwa maapplication. Atrunnion-mounted valve^[4]ine zvimwe zvinotsigira michina—dzinde kumusoro uye trunnion pasi—yakabata bhora. Izvi zvinoita kuti ive yakanaka kune yakakwirira-pressure kana yakakura kwazvo mavharuvhu. Mhando mbiri dzinotevera dzinenge kukura kwegomba kuburikidza nebhora. Ayakazara-chiteshi(kana kuti yakazara-yakazara) valve ine buri rakaenzana nepombi, zvichiita kuti pasave nemuganhu wekuyerera. Akuderedzwa-chiteshivharafu ine buri diki. Izvi zvakanyatsonaka kune akawanda mamiriro uye zvinoita kuti valve ive diki uye inokwanisika.

Kuenzanisa Marudzi mana Makuru

Unoziva sei kana vharuvhu yebhora yakazaruka kana kuvharwa?

Uri kuda kucheka mupombi, asi une chokwadi chekuti vharuvhu yakavharwa? Kukanganisa kwakapusa pano kunogona kutungamira kune hombe tsvina, kukuvara kwemvura, kana kunyange kukuvara.

Unogona kuziva kana abhora vharafuyakavhurika kana kuvharwa nekutarisa pamire mubato maererano nepombi. Kana mubato wakaenzana nepombi, valve yakazaruka. Kana mubato uri perpendicular (kuumba "T" chimiro), valve yakavharwa.

Ichi ndicho chikamu chakakosha uye chakakosha cheruzivo kune chero munhu anoshanda nemavharuvhu ebhora. Mubato wemubato chiratidzo chakananga chekuona nzvimbo yebhora. Ichi chakareruka dhizaini chimwe chezvikonzero nei mavharuvhu ebhora akakurumbira. Hapana kufungidzira. Ndakambonzwa imwe nyaya kubva kuBudi yemumwe mushandi wechidiki wepaimwe nzvimbo aimhanya-mhanya. Akatarisa pavharuvhu akafunga kuti yadzima, asi yakanga iri vharafu rekare regedhi raida kutenderera kakawanda, uye haana kukwanisa kuona mamiriro aro. Akaita kucheka ndokuzarisa mumba. Nevhavha yebhora, kukanganisa ikoko kunenge kusingabviri kuita. Iyo quarter-turn chiitiko uye yakajeka chibatiso chinzvimbo chinopa ipapo, isina kujeka mhinduro: mumutsetse uri "pa," mhiri "kudzima." Ichi chakareruka chimiro chishandiso chine simba chekuchengetedza.

Ndeupi musiyano uripo pakati peT mhando neL mhando yebhora mavharuvhu?

Iwe unofanirwa kutsausa kuyerera, kwete kungoimisa. Kuraira vheji yakajairwa hakushande, uye kuodha isiriyo yakawanda-yevhavhavhavha yechiteshi inogona kutumira mvura kunzvimbo isiriyo zvachose.

T-mhando uye L-mhando inoreva chimiro chemboro mubhora re 3-way valve. I-L-mhando inogona kutsausa kuyerera kubva kune imwe inlet kuenda kune imwe yeaviri maburi. T-mhando inogona kuita zvimwe chetezvo, uyezve inogona kubatanidza ese matatu madoko pamwechete.

Iyi inzvimbo yakajairika yekuvhiringidzika kune vanhu vanotenga yavo yekutanga 3-nzira vharafu. Ngatifungei nezvevharuvhu ine zviteshi zvitatu: pasi, kuruboshwe, uye kurudyi. AnL-Port^[5]vharafu ine 90-degree bend yakaboorwa kuburikidza nebhora. Mune imwe nzvimbo, inobatanidza chiteshi chepasi kune chiteshi chekuruboshwe. Nekutendeuka kwekota, inobatanidza chiteshi chepasi kune chiteshi chekurudyi. Haikwanise kubatanidza ese ari matatu. Yakanakira kutsausa kuyerera kubva kune imwechete sosi kuenda kunzvimbo mbiri dzakasiyana. AT-Port^[6]vharafu ine "T" chimiro chakaboorwa nebhora. Iine zvimwe zvingasarudzwa. Inogona kubatanidza pasi kuruboshwe, pasi kurudyi, kana inogona kubatanidza kuruboshwe kurudyi (kupfuura nepasi). Zvine hutsinye, zvakare ine chinzvimbo chinobatanidza ese matatu madoko kamwechete, achibvumira kusanganisa kana kutsauka. Chikwata chaBudi chinogara chichibvunza mutengi kuti: "Unoda kusanganisa mafambiro, kana kungochinja pakati pavo?" Mhinduro inobva yavaudza kana T-Port kana L-Port ichidiwa.

L-Port vs. T-Port Kugona

Ndeupi musiyano uripo pakati petrunnion nevharuvhu yebhora inoyangarara?

Sisitimu yako inoshanda pasi pekumanikidzwa kwakanyanya. Kana ukasarudza chivharo chebhora, kudzvinyirira kunogona kuita kuti zvive zvakaoma kutendeuka kana kutoita kuti zvisimbiso zvikundike nekufamba kwenguva.

Muvharuvhu inoyangarara, bhora "rinofamba" pakati pezvigaro, richisundwa nekumanikidza. Mune trunnion valve, bhora rinoshandiswa nemagetsi nepamusoro uye pasi shaft (trunnion), iyo inotora kudzvinyirira uye inoderedza kushungurudzika pazvigaro.

Musiyano uri pamusoro pekutonga simba. Muchiyeroinoyangarara bhora vharafu^[7], kana vharuvhu yakavharwa, mhepo yekumusoro inosunda bhora zvakasimba kuchigaro chepasi. Simba iri rinogadzira chisimbiso. Kunyange zvazvo ichishanda, izvi zvinogadzirawo kuputika kukuru, izvo zvinogona kuita kuti valve iome kutendeuka, kunyanya muhukuru hukuru kana pasi pekumanikidzwa kukuru. Atrunnion-mounted valve^[8]inogadzirisa dambudziko iri. Bhora rinoiswa panzvimbo nerutsigiro rwetrunnion, kuti risasundirwe nekuyerera. Dzvinyiriro panzvimbo pacho inosundidzira zvigaro zvakatakurwa-zvitubu zvichipikisana nebhora rakamira. Iyi dhizaini inotora simba rakakura, zvichikonzera yakaderera torque (zviri nyore kutendeuka) uye hupenyu hurefu hwechigaro. Ichi ndicho chikonzero kune yakakwira-kudzvanywa maindasitiri maapplication, kunyanya muindasitiri yemafuta negasi, trunnion mavharuvhu ndiwo anodiwa mwero. Kune akawanda maPVC masisitimu, madhindindi akadzikira zvekuti valve inoyangarara inoshanda zvakakwana.

Inoyangarara vs. Trunnion Head-to-Head
