Pane chinodikanwa chakasimba chekuisa kutungamira kwemavharuvhu ebhora?

Kuiswa kwekutungamira kwemavharuvhu ebhora kunoenderana zvakanyanya nemhando yavo uye maitiro ekugadzira. Zvakawanda zvakajairikabhora mavharuvhuhavana kurambidzwa nzira, asi mhando dzakakosha dzinoda kunyatsoteera kune yakaratidzwa gwara rekuiswa. Iyo chaiyo ongororo yakaita seinotevera:

Mavharuvhu ebhora akajairika, akadai seakajairika anoyangarara bhora mavharuvhu uye akagadziriswabhora mavharuvhu, kazhinji havana yakasimba yekuisa kutungamira zvinodiwa. Kuvhura nekuvhara chikamu cherudzi urwu rwevhavha yebhora ibhora rine mugero pakati. Kana vharafu yebhora yanyatsovhurika, yepakati inokwanisa kuyerera ichiita kunge isina kuvharika kubva kune chero kumagumo kwenzira yebhora kuenda kune imwe magumo. Nheyo yekuisa chisimbiso inovimba nechigaro chevharuvhu chiri kudzvanywa zvakasimba kutarisana nepasi pasi pe pre tension kana yepakati kumanikidzwa, kuwana bidirectional chisimbiso. Naizvozvo, zvese zvakanaka uye zvisina kunaka kuisirwa zvinogona kushanda zvakajairika. Semuyenzaniso, mavharuvhu ebhora anoyangarara anowanzo kuwanikwa mumba uye madiki-dhayamita mapaipi anogona kusangana nezvinodiwa zvekushandisa kana akaiswa mumativi ese pasina kunyorwa kwakakosha.

Zvisinei, kune mamwe marudzi anokosha ebhora mavharuvhuiyo yekuisa nzira yakakosha. Mavharuvhu ane mavara anotungamira achange aine miseve yakanyorwa zvakajeka pamutumbi wevharuvhu inoratidza mafambiro epakati, izvo zvinoreva kuti chimiro chemukati chevharuvhu chakagadzirwa uye chakagadziridzwa kune chaiyo kuyerera kwakananga. Reverse installation inogona kukanganisa chisimbiso mhedzisiro kana hupenyu hwesevhisi. Nheyo yeV-shaped regulating ball valve ine V-shaped kuvhura, yakanyatsogadzirirwa kugadzirisa kuyerera nezvinodiwa zvakajeka zvekuyerera. Reverse kuisirwa kunogona kushandura kuyerera maitiro, zvichitungamira kune isina kurongeka mutemo uye kunyange kukurumidza kupfeka chisimbiso. Nzira nhatu uye nzira ina bhora mavharuvhu ane yakaoma kuyerera migero uye inofanira kuiswa maererano neyakagadzirirwa kuyerera kutungamira, zvikasadaro kufanotemerwa kwepakati kugovera kana kushandura basa hakugone kuwanikwa. Mavharuvhu ebhora ane zvinobatisa, seaya ane magetsi kana pneumatic actuators, kunyangwe vharafu pachayo inogona kunge iri bi-directional, iyo yakasarudzika chinzvimbo cheiyo actuator (kazhinji yakavhurika kana kazhinji yakavharwa) yakavharirwa neiyo pombi system dhizaini. Panguva yekuisa, inofanirwa kuve nechokwadi chekuti valve iri muhurongwa hwekuchengetedza inodiwa nyika (yakavhurika zvizere kana yakavharwa zvizere) kana actuator ichidzimwa kana kubviswa.
