Ivhavha yekuyamura, inozivikanwawo sevhavha yekudzivirira simba (PRV), imhando yevhavhavhavha yekudzivirira inoshandiswa kugadzirisa kana kuderedza kudzvinyirira muhurongwa.Kana dzvinyiriro isina kudzorwa, inogona kukwira uye kuguma nekukanganiswa kwemaitiro, chiridzwa kana kutadza kwemidziyo, kana moto.Nekugonesa iyo yakadzvinyirirwa mvura kuti ibude muhurongwa kuburikidza nenzira yekubatsira, kudzvanywa kunoderedzwa.Kudzivirira midziyo yekumanikidza uye zvimwe midziyo kubva mukumanikidzwa kunodarika miganhu yavo yekugadzira, iyovharafu yekuyamurainovakwa kana kurongerwa kuti ivhure pane yakatarwa set pressure.

Thevharafu yekuyamurainova "nzira yekudzivirira kushoma" kana kudzvanywa kweseti kwapfuura nekuti vharafu inomanikidzwa kuvhurika uye imwe yemvura inodzoserwa mumugero wekubatsira.Musanganiswa wemvura, gasi, kana mvura-gasi inotsauswa mumasisitimu ane zvinwiwa zvinobvira inogona kudzoserwa kana kuburitswa.

[1] ingave inotumirwa kuburikidza nepiping system inozivikanwa seyekuvhuvhuta musoro kana yekuyamura musoro kune nechepakati, yakakwira gasi flare kwainopiswa, ichiburitsa gasi rinopisa rinopisa mumhepo, kana nekudzikira kwakadzika, kuyerera kwemhute yekudzoreredza system.

[2] Mumasisitimu asiri ane ngozi, mvura inogarwa ichiburitswa mumhepo kuburikidza nepombi yekuburitsa yakakodzera iyo inomisikidzwa zvakachengeteka kune vanhu uye inovakwa kudzivirira kupindira kwemvura, izvo zvinogona kukanganisa seti yekusimudza pressure.Dzvinyiriro inomira kuvaka mukati memudziyo sezvo mvura inotungamirwa.Ivhavha inovhara kana dzvinyiriro inosvika pakugadzirisa zvakare.Kuwanda kwekumanikidzwa kunofanira kuderedzwa pamberi pevhavha yekudzoka zvakare inozivikanwa se blowdown, iyo inowanzoratidzwa sechikamu chepakati pekugadzirisa.Mamwe mavharuvhu anoratidza anochinjika blowdowns, uye blowdown inogona kuchinjika pakati pe2% ne20%.

Zvinokurudzirwa kuti nzvimbo yevharuvhu yekuyamura mune high-pressure gasi masisitimu ive mumhepo yakavhurika.Kuvhurwa kwevharuvhu yekuyamura kunokonzeresa kudzvanywa kwepombi kuzasi kwevharuvhu yekuyamura mune masisitimu uko chinobuda chakabatana nepombi.Izvi zvinowanzoreva kuti kana kudzvanywa kunodiwa kwawanikwa, vharafu yekuyamura haizodzokeri zvakare.Izvo zvinonzi "zvakasiyana" mavharuvhu ekuyamura anowanzo shandiswa mune idzi masisitimu.Izvi zvinoratidza kuti dzvinyiriro iri kungozvishandisa panzvimbo diki pane kuvhurwa kwevharuvhu.

Iko kubuda kwevhavha yevhavha kunogona nyore kuchengeta valve yakazaruka kana vheji yakavhurwa sezvo kumanikidzwa kunofanira kudonha zvakanyanya pamberi pekuvhara.Sezvo dzvinyiriro mupombi yepombi inokwira ichikwira, mamwe mavharuvhu okuyamura akabatanidzwa kune pombi yokubuda nayo anogona kuvhurika.Ichi chinhu chekuchengeta mupfungwa.Izvi zvinogona kuguma nemaitiro asina kunaka.
