Kunyangwe patent yekutanga yevharuvhu yebhora yakapihwa muna 1871, zvinotora makore 85 kuti vharuvhu yebhora ibudirire mukutengeserana. Polytetrafluoroethylene (PTFE, kana "Teflon") yakawanikwa panguva yekugadzira bhomba reatomu panguva yeHondo Yenyika II, iyo ichava chinhu chinokonzeresa kutanga indasitiri yevharuvhu yebhora. Mavharuvhu ebhora anowanikwa muzvinhu zvese kubva kubrass kusvika kusimbi yekabhoni uye simbi isina tsvina kusvika kuzirconium.

Chigaro chakasununguka
Vharuvhu yeVharuvhu yeVM SUM21 BALL Flanged Ball Valve yeVharuvhu yeVharuvhu diki dzebhora dzinoyangarara dzinogona kushandiswa mumabasa akasiyana-siyana, kubva pamapombi epamba kusvika kumapombi ane makemikari anonyanya kudiwa. Chigaro chinonyanya kufarirwa chemavharuvhu aya imhando yethermoplastic, senge PTFE. Zvigaro zveTeflon valve zvinoshanda zvakanaka nekuti zvakapfava zvakakwana kuti zvivhare zvakanaka pamabhora esimbi akaposhwa, asi zvakasimba zvakakwana kuti zvisabude muvharuvhu. Matambudziko maviri makuru nemavharuvhu aya ezvigaro zvakapfava ndeekuti anokwenywa zviri nyore (uye anogona kudonhedza mvura), uye tembiricha inogumira pasi penzvimbo yekunyunguduka kwechigaro chethermoplastic - inenge 450oF (232oC), zvichienderana nechinhu chechigaro.

Chimwe chinhu chinowanikwa mumavharuvhu mazhinji ebhora anoyangarara echigaro ndechekuti anogona kuvharwa zvakanaka kana pakaitika moto unokonzera kuti chigaro chikuru chinyunguduke. Izvi zvinonzi dhizaini isingatsvi; ine homwe yechigaro isingangobati chete chigaro chinoyangarara, asiwo inopa pamusoro pechigaro chesimbi chinopa chisimbiso chisina kukwana kana chasangana nebhora. Sekureva kweAmerican Petroleum Institute (API) 607 kana 6FA fire test standards, vharuvhu inoedzwa kusimbisa dhizaini yekudzivirira moto.

Dhizaini yeTrunnion

Musiyano uripo pakati petrunnion nerumwe rudzi rwefloating ndeyekuti trunnion ball inosungirirwa mumuviri mukuru ne trunnion yepasi (tsvimbo pfupi yekubatanidza) netsvimbo yepamusoro. Sezvo bhora risingakwanise "floating" muchigaro chevharuvhu kuti rivharwe zvine simba, chigaro chevharuvhu chinofanira kufloating pabhora. Dhizaini yechigaro che trunnion inoita kuti chigaro chikurudzirwe nekumanikidzwa kwepamusoro uye kumanikidzwa kupinda mubhora kuti chivharwe. Nekuti bhora rakanyatsoiswa panzvimbo, kunze kwekutenderera kwaro kwe90o, simba rinoshamisa remvura nekumanikidzwa hazvizopinze bhora muchigaro chevharuvhu. Pane kudaro, simba rinongoshanda panzvimbo diki iri kunze kwechigaro chinofloating.
