Mavharuvhu eNewsway Valve Company (NSW) anoshandiswa zvakanyanya muminda yakasiyana-siyana yemapaipi, anogona kuzadzisa zvinodiwa zvinotevera zvemavharuvhu emapaipi
1. Cheka wosunungura chinhu chacho
Iri ndiro basa guru revharuvhu. Kazhinji, vharuvhu ine nzira yekuyerera yakatwasuka inosarudzwa, uye kuramba kwayo kuyerera kushoma.
Mavharuvhu akavharwa pasi (Mavharuvhu epasi, mavharuvhu eplunger) haawanzo shandiswa nekuda kwenzira dzawo dzinoyerera dzakakombama uye kuramba kuyerera kwakawanda kupfuura mamwe mavharuvhu. Kana kuramba kuyerera kwakawanda kuchibvumidzwa, vharuvhu yakavharwa inogona kushandiswa.
2. Ckuyerera kwekudzora
Kazhinji, vharuvhu iri nyore kugadzirisa kuyerera kwemvura inosarudzwa senzira yekudzora kuyerera kwemvura. Vharuvhu yekuvharira pasi (yakadai sevharuvhu yepasi rose) yakakodzera chinangwa ichi nekuti saizi yechigaro chayo inoenderana nekurovera kwechikamu chekuvhara.
Mavharuvhu anotenderera (Mavharuvhu epuragi, mavharuvhu eshavishavi, mavharuvhu ebhora) uye mavharuvhu anochinjika (mavharuvhu ekupinza, mavharuvhu ediaphragm) anogonawo kushandiswa kudzora kudhonza, asi anowanzo shandiswa chete mukati mehukuru hwakaganhurirwa hwemavharuvhu.
Vharuvhu yegedhi inoshandisa gedhi rakaita sedhisiki kuita kufamba-famba kuenda kuburi rechigaro chevharuvhu rakatenderera. Inogona kudzora kuyerera zvakanaka chete kana iri pedyo nenzvimbo yakavharwa, saka haiwanzo shandiswa kudzora kuyerera kwemvura.
3. Kudzokera shure uye kusundira
Zvichienderana nezvinodiwa pakudzosera shure nekudzima, rudzi urwu rwevharuvhu runogona kuva nemigero mitatu kana kupfuura.Mavharuvhu ebhora ane nzira nhatuakakodzera zvikuru pachinangwa ichi. Saka, mavharuvhu mazhinji anoshandiswa pakudzosera nekukamura kuyerera kwemvura anosarudza rimwe remavharuvhu aya.
Asi mune dzimwe nguva, mamwe marudzi emavharuvhu anogona kushandiswawo pakudzosera kumashure nekuchinjika chero bedzi mavharuvhu maviri kana anopfuura akabatana zvakanaka.
4. Pakati nepakati ine zvidimbu zvakasungirirwa
Kana paine zvidimbu zvakasungirirwa mukati mechinhu, zvinonyanya kukodzera kushandisa vharuvhu ine simba rekupukuta pakutsvedza kwechikamu chinovhara pamusoro pechisimbiso.
Kana kufamba kwechikamu chekuvhara kuenda kuchigaro chevharuvhu kwakamira, kunogona kubata zvidimbu. Saka, vharuvhu iyi yakakodzera chete kune zvidimbu zvekutanga zvakachena kunze kwekunge zvinhu zvekuvhara zvichibvumira zvidimbu kuti zvibatanidzwe. Mavharuvhu ebhora nemavharuvhu eplug ane simba rekupukuta pamusoro pekuvhara panguva yekuvhura nekuvhara, saka akakodzera kushandiswa muzvidimbu zvine zvidimbu zvakamiswa.
