Umuyoboro wa SDV (Hagarika Valve) ni valve ifungura V ifite ishusho ya V kuruhande rumwe rwumupira wamaguru. Muguhindura ifungura rya spol, agace kambukiranya igice cyimyanya yo hagati irahindurwa kugirango ihindure imigezi. Irashobora kandi gukoreshwa muguhindura kugirango tumenye gufungura cyangwa gufunga umuyoboro. Ifite ingaruka yo kwisukura, irashobora kugera kubintu bito byahinduwe murwego ruto rwo gufungura, igipimo gishobora guhinduka ni kinini, kibereye fibre, uduce duto, itangazamakuru ryihuta.
Gufungura no gufunga igice cyumupira wubwoko bwa V ni umuzingi ufite umuyoboro uzenguruka, kandi ibice byombi bihujwe na bolt hanyuma bikazenguruka 90 ° kugirango bigere ku ntego yo gufungura no gufunga.
Ikoreshwa cyane muri sisitemu yo kugenzura byikora ya peteroli, inganda zimiti nibindi.

1. Kurwanya amazi ni bito, coefficient de flux nini, igipimo gishobora guhinduka ni kinini. Irashobora kugera kuri: 100: 1, nini cyane kuruta igipimo gishobora kugereranywa cyimyanya imwe igororotse igenga valve, imyanya ibiri igenga valve hamwe nintoki igenga valve. Ibiranga imigendekere yabyo ni hafi ijanisha.
2. Kashe yizewe. Urwego rwo kumeneka rwicyuma rukomeye rwa kashe ni Icyiciro cya IV cya GB / T4213 "Pneumatic Control Valve". Urwego rwo kumeneka rworoshye rwa kashe ni Urwego V cyangwa Icyiciro cya VI cya GB / T4213. Kuburyo bukomeye bwo gufunga, umupira wibanze wumupira urashobora gukorwa mububiko bwa chromium bukomeye, hejuru ya cobalt ishingiye kuri cbide ya sima, gutera tungsten karbide yambara idashobora kwangirika, nibindi, kugirango ubuzima bwa serivisi bwa kashe yibanze.
3. fungura kandi ufunge vuba. V-umupira wumupira wa Vale ni inguni ya stroke, kuva ifunguye neza kugeza ifunguye neza Inguni 90 °, ifite ibikoresho bya AT piston pneumatic actuator irashobora gukoreshwa mugihe cyo guca vuba. Nyuma yo kwishyiriraho amashanyarazi ya valve, irashobora guhindurwa ukurikije ibimenyetso bisa 4-20Ma.
4. Imikorere myiza yo guhagarika. Igicucu gifata 1/4 cyimiterere yimiterere hamwe nintebe imwe. Iyo hari ibice bikomeye muburyo bwo hagati, kuziba kwa cavity ntibizabaho nkibisanzwe O-umupira wumupira. Nta tandukanyirizo riri hagati yumupira wa V nintebe, ifite imbaraga nini zo gukata, cyane cyane zibereye kugenzura ihagarikwa nibice bikomeye birimo fibre cyangwa uduce duto duto. Mubyongeyeho, hari imipira ya V ifite imipira ifite imipira yisi yose, ikwiranye nuburyo bwumuvuduko mwinshi kandi irashobora kugabanya neza ihinduka ryimiterere yumupira mugihe itandukaniro ryinshi ryumuvuduko. Ifata intebe imwe yo gufunga cyangwa imyanya ibiri yo gufunga intebe. Umupira wumupira wa V ufite kashe yintebe ebyiri ukoreshwa cyane mugutunganya isuku yo hagati, kandi urwego rufite ibice bishobora gutera akaga ko gufunga umwobo wo hagati.
5. V-ubwoko bwumupira wumupira ni imiterere yumupira uhamye, intebe yuzuye amasoko, kandi irashobora kugenda inzira yinzira. Irashobora guhita yishyura imyenda yangiritse, ikongerera igihe cya serivisi. Isoko ifite isoko ya mpandeshatu, isoko yumuraba, isoko ya disiki, compression ya silindrike nibindi. Iyo igikoresho gifite umwanda muto, birakenewe kongeramo impeta zifunga isoko kugirango irinde umwanda. Ku ntebe ebyiri zifunze isi yose V-umupira, imipira ireremba ikoreshwa.
. Fata ingamba zo gutwara amashanyarazi hagati yumubiri wa valve, uruti nizunguruka. Kurikiza GB / T26479 imiterere irwanya umuriro hamwe na GB / T12237 ibisabwa antistatike.
. Imiterere isanzwe ikoreshwa ni zeru eccentric. Imiterere ya eccentric irashobora kurekura vuba intebe kuva kuntebe iyo ifunguye, kugabanya kwambara impeta ya kashe no kongera ubuzima bwa serivisi. Iyo ifunze, imbaraga zidasanzwe zirashobora kubyara imbaraga zo kashe.

10.ceramic ball valve nayo ifite V-shusho yumupira wibanze. Kurwanya kwambara neza, ariko kandi birwanya aside na alkali birwanya ruswa, bikwiranye no kugenzura itangazamakuru rya granular. Florine itondekanye umupira wumupira kandi ifite imiterere yumupira wa V ifite imiterere ya V, ikoreshwa mugutunganya no kugenzura aside hamwe nibitangazamakuru byangiza. Porogaramu urwego rwa V ubwoko bwumupira wa valve ni byinshi kandi binini.
Serivise nyuma yo kugurisha ya valve ya SDV (Shut Down Valve) (V port) ni ngombwa cyane, kuko serivisi yigihe kandi cyiza nyuma yo kugurisha irashobora kwemeza imikorere yayo yigihe kirekire kandi ihamye. Ibikurikira nibyo nyuma yo kugurisha ibikubiye muri serivise zimwe zireremba:
1.Gushiraho no gutangiza: Abakozi ba serivise nyuma yo kugurisha bazajya kurubuga gushiraho no gukuramo umupira wamaguru ureremba kugirango barebe ko bihagaze neza kandi bisanzwe.
2.Gufata neza: Komeza ubungabunge umupira wamaguru ureremba kugirango umenye neza ko umeze neza kandi ugabanye igipimo cyo gutsindwa.
3.Gukemura ibibazo: Niba umupira ureremba umupira wananiwe, abakozi ba serivise nyuma yo kugurisha bazakemura ibibazo kurubuga mugihe gito gishoboka kugirango barebe imikorere isanzwe.
4.Kuvugurura no kuvugurura ibicuruzwa: Mu gusubiza ibikoresho bishya n’ikoranabuhanga rishya rigaragara ku isoko, abakozi ba serivisi nyuma yo kugurisha bazahita basaba kuvugurura no kuzamura ibisubizo kubakiriya kugirango babaha ibicuruzwa byiza bya valve.
5. Amahugurwa yubumenyi: Abakozi ba serivisi nyuma yo kugurisha bazatanga ubumenyi bwa valve kubakoresha kugirango bongere urwego rwo gucunga no gufata neza abakoresha bakoresha imipira ireremba. Muri make, nyuma yo kugurisha serivise yumupira wamaguru ireremba igomba kwemezwa mubyerekezo byose. Gusa murubu buryo burashobora kuzana abakoresha uburambe bwiza no kugura umutekano.
