Zvinotevera ipfupiso yehuwandu hwedhayamita yemavharuvhu ane nzira dzakasiyana dzekubatanidza uye mhando dzemaumbirwo, zvichibva pamitemo yeindasitiri yakajairika uye maitiro ekushandisa. Sezvo huwandu hwedhayamita chaiyo hunogona kusiyana zvichienderana nemugadziri uye mamiriro ekushandisa (senge huwandu hwekumanikidza, mhando yepakati, nezvimwewo), chinyorwa chino chinopa data remavharuvhu ezfa.
Inotevera idata reruzivo rwakawanda mudhayamita yezita (DN, mm).
1. Dhayamita yemavharuvhu eshavishavi yakarongwa nenzira yekubatanidza
1. Vharuvhu yeshavishavi reWafer
- Dhayamita yedhayamita: DN15–DN600
- Tsananguro: Mavharuvhu eWafer butterfly akapfava uye anowanzo shandiswa mumasystem ekumanikidza ari pakati nepakati nepasi. Ane dhayamita yakakura uye akakodzera mapaipi madiki nepakati. Kana ikadarika DN600, unogona kusarudza vharuvhu yeflange butterfly imwe chete (DN700-DN1000). Madhayamita akakura zvakanyanya (akadai seari pamusoro peDN1200) haawanzo kuwanikwa nekuda kwezvinodiwa zvakanyanya zvekuisa nekusunga.
2. Vharuvhu yeshavishavi ine flange mbiri
- Dhayamita yedhayamita: DN50–DN3000
- Tsananguro: Vharuvhu yeshavishavi ine flange mbiri yakakodzera zviitiko zvinoda kugadzikana kwakanyanya kwechimiro uye kushanda kwekuvhara. Ine dhayamita yakakura uye inowanzoshandiswa mumasisitimu makuru emapaipi akadai sekuchenesa mvura, zviteshi zvemagetsi, nezvimwewo.
3. Vharuvhu imwe chete yeshavishavi inopinza
- Dhayamita yedhayamita: DN700–DN1000
- Tsananguro: Mavharuvhu eflange rimwe chete anoshandisa zvinhu zvishoma pane mavharuvhu eflange maviri kana lug, izvo zvinoderedza mari yekugadzira uye zvinoderedzawo mari yekufambisa. Anosungirirwa paflange yepombi uye anonamirwa panzvimbo.
4. Vharuvhu yeshavishavi yeLug
- Dhayamita yedhayamita: DN50–DN600
- Tsananguro: Mavharuvhu eLug butterfly (Lug type) akakodzera masisitimu ari kumagumo kwepombi kana anoda kupatsanurwa kakawanda. Rudzi rwedhayamita diki uye rwepakati. Nekuda kwemiganhu yechimiro, mashandisirwo edhayamita yakakura haawanzoitiki.
5. Vharuvhu yeshavishavi yerudzi rweU
- Rudzi rweCaliber: DN100–DN1800
- Tsananguro: Mavharuvhu emhando yeU anonyanya kushandiswa pamapaipi ane dhayamita hombe, akadai semvura yemuguta, kurapwa kwetsvina, nezvimwewo, uye chimiro chacho chakakodzera mamiriro ekuyerera kwakanyanya uye musiyano wepressure yakaderera.
| Tsananguro | Hukuru Hwakafanana (DN) | Zvinyorwa Zvikuru |
|---|---|---|
| Vharuvhu yeBhatafurayi yeMvura | DN15-DN600 | Chimiro chidiki, chinochengetedza mari, chinoshandiswa zvakanyanya mumasisitimu ane kumanikidzwa kwakaderera kusvika pakati nepakati; saizi hombe kune mabasa asiri akakosha. |
| Valve yeButterfly Lug | DN50-DN600 | Yakakodzera kushandiswa zvisina simba uye masisitimu anoda kubviswa kubva kudivi rimwe. Kubata kumanikidzwa kuri nani zvishoma pane rudzi rwemvura. |
| Valve yeButterfly ine Flanged imwe chete | DN700-DN1000 | Inowanikwa mumasisitimu akavigwa kana kuti asina kumanikidzwa zvakanyanya; huremu hwakareruka uye huri nyore kuisa. |
| Valve yeButterfly Yakakamurwa Kaviri | DN50-DN3000 (kusvika kuDN4000 mune dzimwe nguva) | Yakakodzera kushandiswa zvine simba guru, dhayamita hombe, uye zvakakosha; kushanda zvakanaka kwazvo pakusunga chisimbiso. |
| Vharuvhu yeU-rudzi rweButterfly | DN50-DN1800 | Kazhinji rabha inoputirwa kana kuti inoputirwa zvakakwana kuti isapararire ngura mumasevhisi emakemikari. |

2. Mhando dzemavharuvhu eshavishavi dzakarongwa zvichienderana nerudzi rwechimiro
1. Vharuvhu yeshavishavi iri pakati
- Rudzi rweCaliber: DN50–DN1200
- Tsananguro: Vharuvhu yebhururu yepakati (chisimbiso chakapfava kana chisimbiso che elastic) ine chimiro chakareruka, chakakodzera kushandiswa pakupisa kwakaderera uye tembiricha yakajairika, ine huwandu hwema caliber ari pakati nepakati, uye inoshandiswa zvakanyanya mumvura, gasi nedzimwe nzira.
2. Vharuvhu yeshavishavi ine eccentric mbiri
- Rudzi rweCaliber: DN50–DN1800
- Tsananguro: Vharuvhu yeshavishavi ine jira rakasiyana-siyana inoderedza kupera kwechisimbiso kuburikidza nekugadzirwa kwayo, yakakodzera masisitimu ekumanikidzwa kwakaderera uye kwepakati, ine mhando dzakasiyana dzemakasi, uye inowanzoshandiswa mumafuta negesi, makemikari nedzimwe nzvimbo.
3. Vharuvhu yeshavishavi ine eccentric katatu
- Rudzi rweCaliber: DN100–DN3000
- Tsananguro: Vharuvhu yeshavishavi ine eccentric katatu (yakaoma) yakakodzera tembiricha yakakwira, kumanikidzwa kwakakwira uye mamiriro ekushanda akaomarara. Ine caliber yakakura uye inowanzoshandiswa mumapaipi makuru eindasitiri, akadai semagetsi, petrochemical, nezvimwewo.
| Tsananguro | Saizi Yakajairika | Zvinyorwa Zvikuru |
|---|---|---|
| Vharuvhu yeButterfly Yakakombama | DN40-DN1200 (kusvika kuDN2000 mune dzimwe nguva) | Mitsetse yepakati pema stem ne disc zvakapfava uye zvakakodzera kushandiswa pakuderedza kumanikidzwa. |
| Valve yeButterfly yeKubvisa Kaviri | DN100-DN2000 (kusvika kuDN3000) | Dhisiki inokurumidza kubva pachigaro pakuvhurika kuderedza kupera, inoshandiswa mumamiriro ezvinhu ane kumanikidzwa kuri pakati nepakati. |
| Valve yeButterfly yeKubvisa Katatu | DN100-DN3000 (kusvika kuDN4000) | Yakagadzirirwa kushandiswa pakupisa kwakanyanya, kumanikidzwa kwakanyanya, uye kusaburitsa mvura, kazhinji inenge yakagara nesimbi. |
