Ruzivo rwekutanga rwePVC bhora vharafu
PVC bhora mavharuvhu anogona kushandiswa kudzora uye kudzora kuyerera kwemvura mukuwedzera pakunyanya kushandiswa kujoina kana kubvisa pombi media. Inopa zvinotevera zvinobatsira pamusoro pemamwe mavharuvhu. Pane kushomeka kwemvura. Pakati pemavharuvhu ese, vharuvhu yebhora ine kushomeka kwemvura. Kuramba kwayo kwemvura kwakadzikira, zvisinei nekuti ivharuvhu yebhora ine dhayamita diki.
Rudzi rutsva rwebhora vharafu yakagadzirwa neUPVCyakagadzirwa kuti isangane nezvinodiwa zvemhando dzakasiyana siyana dzemapaipi emvura. Zvakanakira muviri wevharuvhu zvinosanganisira huremu hwayo, huremu hwepamusoro, dhizaini dhizaini, chitarisiko chakanaka, nyore kuisa, huwandu hwemashandisirwo, hutsanana uye husina chepfu kuvaka, kuramba kupfeka, nyore disassembly, uye nyore kugadzirisa.
PPRPVDF, PPH,CPVC, uye zvimwe zvinhu zvepurasitiki zvinoshandiswawo kugadzira mavharuvhu ebhora epurasitiki kuwedzera kuPVC. Mavharuvhu ebhora akagadzirwa nePVC ane akasarudzika corrosion resistance. Uchishandisa F4, mhete yekuvhara inovhara. Hupenyu hwesevhisi hurefu nekuda kwekusagadzikana kwecorrosion. Kutenderera kunobatsira kunochinjika.
Sevhavhavha yebhora yakabatanidzwa, iyoPVC bhora vharafuinopa mashoma masosi ekudonha, simba rakakwirira, uye iri nyore kuunganidza nekubvisa. Kuisa nekushandiswa kwevharuvhu yebhora: Kudzivirira kudonha kunokonzerwa nekutsvedza kweflange, mabhaudhi anofanirwa kusungwa zvakaenzana kana maflange kumagumo ese akanamatira papombi. Shandura mubato wakatarisa wachi kuti uvhare, neimwe nzira kuti uvhure. Inogona kushandiswa chete kuvharira uye nzira, uye kugadzirisa kuyerera hakushandi. Zvinwiwa zvine zvimedu zvakaoma zvinogona kukwenya zviri nyore pamusoro pebhora.
Nhoroondo Yebhora Mavharuvhu
Muenzaniso wekutanga wakafanana nebhora vharafuivharuvhu ine patented naJohn Warren muna 1871. Ivharuvhu yesimbi ine bhora rendarira nechigaro chendarira. Warren akazopa dhizaini yake yedhizaini yebhora rendarira kuna John Chapman, mukuru weChapman Valve Company. Chero chikonzero, Chapman haana kumboisa dhizaini yaWarren mukugadzira. Pane kudaro, iye nevamwe vagadziri vevharuvhu vave vachishandisa magadzirirwo ekare kwemakore mazhinji.
Mavharuvhu ebhora, anonziwo mavharuvhu ebhora, akazopedzisira aita basa munguva yeHondo Yenyika II. Munguva iyi, mainjiniya akaigadzira kuti ishandiswe mumauto emafuta masisitimu endege. Mushure mekubudirira kwebhora mavharuvhumuHondo Yenyika II, mainjiniya akashandisa mavharuvhu ebhora kumaindasitiri ekushandisa.
Imwe yezvakanyanya kukosha zvine chekuita nemavharuvhu ebhora muma1950 yaive kuvandudzwa kweTeflon uye kushandiswa kwayo kwakazotevera sechinhu chevhavha yebhora. Mushure mekubudirira kwebudiriro yeTeflon, mabhizinesi mazhinji akadai seDuPont akarwira kodzero yekuishandisa, nekuti vaiziva kuti Teflon yaigona kuunza mabhenefiti makuru emusika. Pakupedzisira, kambani inopfuura imwe yakakwanisa kugadzira mavharuvhu eTeflon. Teflon bhora mavharuvhu anochinjika uye anogona kugadzira zvisimbiso zvakanaka mumativi maviri. Mune mamwe mazwi, ivo vari bidirectional. Iwo zvakare leak proof. Muna 1958, Howard Freeman ndiye aive mugadziri wekutanga kugadzira vharafu yebhora ine chigaro chinochinjika cheTeflon, uye dhizaini yake yaive nemvumo.
Nhasi, mavharuvhu ebhora akagadzirwa nenzira dzakawanda, kusanganisira kuenderana kwavo kwezvinhu uye maapplication anogoneka. Mukuwedzera, vanogona kushandisa CNC machining uye purogiramu yekombiyuta (yakadai seButton model) kugadzira mavharuvhu akanaka. Nenguva isipi, vagadziri vevhavha yebhora vachakwanisa kupa sarudzo dzakawanda dzezvigadzirwa zvavo, kusanganisira kuvaka kwealuminium, kusapfeka zvishoma uye hukuru hwekugwinya, izvo zvinobvumira vashandi kuti vapfuure huwandu hwakasiyana hwemvura kuburikidza nevhavha pahuwandu hwekuyerera.
