Varuvhu mudziyo wekudzora mafambiro, mafambiro, nekwakananga kwemvura.Mvura inodzorwa inogona kunge iri mvura, gasi, musanganiswa wegasi-mvura, kana musanganiswa wakasimba-mumvura.Valve kazhinji nemuviri wevharuvhu, chivharo, chigaro, yakavhurika uye yekuvhara zvidimbu, dhiraivha michina, zvisimbiso uye fasteners, zvichingodaro.Basa rekutonga revhavha rinoenderana nedhiraivha yekutyaira kana fluid kutyaira kusimudza, kutsvedza, kutenderera kana kutenderera kutenderera kwekuvhura uye kuvhara zvikamu kuti uchinje saizi yenzvimbo yekumhanya.

Mavharuvhu ane zvakasiyana-siyana zvekushandisa uye ane hukama zvakanyanya nehupenyu hwevanhu hwemazuva ese, semapombi epombi dzemvura uye mavharuvhu ekudzikisa mavharuvhu echitofu chepetroleum gasi.Mavharuvhu zvakare akakosha zvinhu mumhando dzakasiyana dzemichina yemagetsi senge injini dzinopisa dzemukati, injini dzehutsi, compressors, pombi, pneumatic actuators, hydraulic drive system mota, ngarava uye ndege.

2,000 BC isati yasvika, maChinese akashandisa mapaipi emushenjere nemavharuvhu emapaipi emvura, magedhi emvura mumigero yekudiridza, uye mavharuvhu ekutarisa kwendiro mukunyungudusa tekinoroji nekuvandudza tekinoroji yekunyungudutsa uye hydraulic muchina, mhangura uye lead plug mavharuvhu akaonekwa muEurope.Nekuunzwa kwebhailer, 1681 yakaunza lever sando rudzi rwekuchengetedza vharafu.1769 uye cheki mavharuvhu aive mavharuvhu ekutanga kusvika Watt chiutsi injini.Kugadzirwa kweinjini yeutsi kwakaunza vharuvhu mumunda weindasitiri yemagetsi.Mukuwedzera kune plug, zororo uye cheki mavharuvhu anoshandiswa muWatt's steam injini, butterfly mavharuvhu anoshandiswa kudzora kuyerera.Nekuwedzera kwekuyerera kwemhepo uye kudzvinyirira, kushandiswa kwevhavhavhavha yevhavha yekudzora kupinza kwemhepo uye kupera kwejini injini haigoni kuzadzisa zvinodiwa, saka kune slide valve.

Gore ra1840 risati uye rapfuura, pakanga paine mavharuvhu epasi ane hunde dzakarukwa uye Wedge Mavharuvhu ane Trapezoidal akarukwa madzinde, yaive budiriro huru mukuvandudzwa kwevharuvhu.Kuonekwa kwemhando mbiri idzi dzemavharuvhu hakuna kungogutsa kuwedzera kudiwa kwekumanikidza uye tembiricha mumaindasitiri akasiyana panguva iyoyo, asi zvakare kugutsa kudiwa kwekuyerera kwemutemo.Kubva ipapo, nekuvandudzwa kweindasitiri yemagetsi emagetsi, indasitiri yepetroleum, indasitiri yemakemikari uye indasitiri yekuvaka ngarava, marudzi ese epamusoro uye epakati mavharuvhu ekumanikidza akagadzirwa nekukurumidza.

Mushure meHondo Yenyika Yechipiri, nekuda kwekugadzirwa kwezvinhu zvepolymer, zvinhu zvekuzora, simbi isina tsvina uye cobalt-based carbide, Old Plug Valve uye butterfly valve zvakashandiswa mukushandiswa kutsva, vharafu yebhora uye diaphragm valve zvakagadziriswa nekukurumidza.Globe mavharuvhu, gedhi mavharuvhu uye mamwe mavharuvhu akawedzera akasiyana uye mhando.Indasitiri yekugadzira mavharuvhu zvishoma nezvishoma yave chikamu chakakosha cheindasitiri yemichina.Valve maererano nekushandiswa kwekushanda inogona kukamurwa kuva block valve, control valve, check valve, diversion valve, kuchengetedza valve, multi-chinangwa valve 6 zvikamu.
