Kuvhara ndekudzivirira kubuda kwemvura, uye musimboti wekuvharwa kwevharuvhu unodzidzwawo kubva pakudzivirira kubuda kwemvura. Pane zvinhu zvakawanda zvinokanganisa mashandiro ekuvharwa kwemvura.mavharuvhu eshavishavi, kunyanya kusanganisira zvinotevera:
1. Chivako chekuvhara
Kana tembiricha kana simba rekuvhara rikaramba richichinja, chimiro chepeya yekuvhara chinochinja. Uyezve, shanduko iyi ichakanganisa uye ichachinja simba riri pakati pepeya dzekuvhara, nokudaro ichideredza mashandiro evharuvhu yekuvhara. Saka, pakusarudza peya, iva nechokwadi chekusarudza peya ine elastic deformation. Panguva imwe chete, nyatsoteererawo ukobvu hwepeya yekuvhara. Chikonzero ndechekuti peya yekuvhara haigone kuenzaniswa zvakakwana. Kana upamhi hwepeya yekuvhara huchikwira, simba rinodiwa rekuvhara rinowedzerwa.
2. Kumanikidzwa kwakananga kwekuisa chisimbiso pamusoro
Kumanikidzwa kwakananga kwenzvimbo yekuvhara kunokanganisa mashandiro ekuvharavharuvhu yeshavishaviuye hupenyu hwevharuvhu. Saka, kumanikidzwa kwakanangana nepamusoro pechisimbiso chinhu chakakoshawo. Mumamiriro ezvinhu akafanana, kumanikidzwa kwakanyanya kwakanangana kunokonzera kukuvara kwevharuvhu, asi kumanikidzwa kudiki kwakanangana kunokonzera kubuda kwevharuvhu. Saka, tinofanira kufunga zvizere nezvekukodzera kwekumanikidzwa kwakanangana pakugadzira.
3. Hunhu hwechinhu chacho
Hunhu hwechinhu chacho hunokanganisawo mashandiro ekuvharavharuvhu yeshavishavi. Hunhu uhwu hwepanyama hunosanganisira tembiricha, viscosity, uye hydrophilicity yepamusoro, pakati pezvimwe. Kuchinja kwetembiricha hakungokanganisi kunonoka kwe sealing pair uye shanduko yehukuru hwezvikamu, asiwo kune hukama husingaparadzanisiki ne viscosity yegesi. Gas viscosity inowedzera kana kuderera nekupisa kuri kuwedzera kana kuderera. Saka, kuti tideredze simba retembiricha pakushanda kwe sealing yevharuvhu, pakugadzira sealing pair, tinofanira kuigadzira sevharuvhu ine thermal compensation senge elastic valve seat. Viscosity ine chekuita nekubvumidzwa kwemvura. Kana iri mumamiriro akafanana, viscosity yakakura, fluid inoderera kupinda kwayo. Hydrophilicity yepamusoro zvinoreva kuti kana paine firimu pamusoro pesimbi, firimu inofanira kubviswa. Nekuda kwefirimu iyi yakatetepa yemafuta, ichaparadza hydrophilicity yepamusoro, zvichikonzera kuvharika kwenzira dzemvura.
4. Hunhu hwepeya yekuisa chisimbiso
Hunhu hweseal pair hunoreva kuti tinofanira kutarisa kusarudzwa, kuenzaniswa uye kugadzirwa kwakarurama kwezvinhu. Semuenzaniso, dhisiki revharuvhu rinoenderana zvakanaka nepamusoro peseal pachigaro chevharuvhu, izvo zvinogona kuvandudza mashandiro eseal.
Kubuda kwevharuvhu kwakajairika muhupenyu nekugadzirwa, izvo zvinogona kukonzera marara kana kuunza njodzi kuhupenyu, senge kubuda kwevharuvhu yemvura yepombi, uye mhedzisiro yakakomba, senge chepfu, inokuvadza, inobvira moto, inoputika uye Kubuda kwemidziyo inoparadza, nezvimwewo, injodzi huru kuchengetedzeka kwemunhu, kuchengetedzeka kwepfuma uye njodzi dzekusvibiswa kwezvakatipoteredza. Sarudza zvisimbiso zvakakodzera zvichienderana nenzvimbo dzakasiyana uye hunhu hwemashandisirwo.
