Mavharuvhu ebhorainoshandiswa mumapaipi egasi chaiwo zvinhu zvakakosha kuti ive nechokwadi chekufambisa kwakachengeteka uye kwakanaka kwegasi rechisikigo. Pakati pemhando dzakasiyana dzemavharuvhu ebhora, trunnion bhora mavharuvhu ndiwo anonyanya kushandiswa mukushandisa kwakadaro. Kunzwisisa misimboti yekugadzira gasi bhora mavharuvhu, kunyanya trunnion bhora mavharuvhu, kwakakosha kune mainjiniya nevashandisi muindasitiri yesimba.
Chimiro uye Basa
Iyo yakagadziriswa axis ball valve ine denderedzwavharafu disc (kana bhora)iyo inotenderera nezve axis yakagadziriswa kudzora kuyerera kwegasi rechisikigo. Iyo valve yakagadzirirwa kubvumira kana kudzivirira kuyerera kwegesi zvichienderana nenzvimbo yebhora. Kana gomba rebhora richienderana nepombi, gasi rinogona kuyerera zvakasununguka; kana bhora richitenderedzwa 90 degrees, kuyerera kwegesi kunovharwa. Iyi nzira iri nyore asi inoshanda inopa nzira yakavimbika yekudzora pombi yekuyerera kwegesi.
Valve Seat Design
Chigaro chevharuvhu chinhu chakakosha chevhavha yebhora sezvo ichipa chisimbiso chepamusoro kudzivirira kubuda kana vharafu yakavharwa. Mukushandiswa kwegasi rechisikigo, pane kazhinji kaviri magadzirirwo makuru ezvigaro zvevharuvhu: zvigaro zvinogadzika uye zvigaro zvesimbi.
1. Zvigaro zvinochinja: Zvigaro izvi zvakagadzirwa nezvinhu zvinochinjika senge rabha kana mapolymer. Ivo vanopa yakanakisa yekuisa chisimbiso zvivakwa, kunyanya kune yakaderera-kumanikidza kunyorera. Iyo elasticity yezvinhu inobvumira kuti ienderane nepamusoro pebhora, ichigadzira chisimbiso chakasimba chinoderedza njodzi yekubuda kwegasi. Zvisinei, zvigaro zvakagadzikana zvinogona kusaita zvakanaka mukupisa kwepamusoro kana hutsinye hwemakemikari nharaunda, uye kushanda kwavo kunogona kuderera nekufamba kwenguva.
2. Zvigaro zvesimbi: Zvigaro zvesimbi zvakagadzirwa nesimbi yakasimba, yakadai sesimbi isina tsvina kana mamwe alloys. Zvigaro izvi zvakakodzerwa nepamusoro-kudzvanywa uye kudziya kwepamusoro-soro zvikumbiro nekuti zvinokwanisa kumira zvakanyanya pasina kukanganisa kuvimbika kwavo. Metal-yakagara bhora mavharuvhu haanyanyi kubatwa nekupfeka uye akakodzera kushandiswa kwenguva refu mumapaipi egasi chaiwo. Nekudaro, ivo vanogona kunge vasingape kuita kwakafanana kwekuisa chisimbiso sezvigaro zvakatsiga, kunyanya pakudzvinyirirwa kwakaderera.
Kufunga Kwekugadzira
Paunenge uchigadzira gasi gasi bhora revhavha, zvinhu zvakawanda zvinofanirwa kutariswa kuti ive nechokwadi chekushanda kwakakwana. Zvinhu izvi zvinosanganisira kushanda nesimba uye tembiricha, rudzi rwegasi rechisikigo riri kutakurwa, uye zvinodikanwa chaizvo zvepombi system. Mainjiniya anofanirwawo kufunga nezve mukana wekuora uye kuvhuvhuta, izvo zvinogona kukanganisa hupenyu uye kuvimbika kwevhavha.
Uye zvakare, kusarudzwa kwe elastomer kana simbi chigaro dhizaini zvinoenderana neiyo chaiyo application. Semuyenzaniso, kana pombi ichishanda pasi pezvinochinja-chinja zvinomanikidza uye tembiricha, simbi yechigaro vharafu inogona kuve yakakodzera. Sezvineiwo, kune maapplication uko kusimba kwakakosha uye mamiriro ekushanda akagadzikana, chigaro che elastomer chingave chiri nani sarudzo.
Misimboti yekugadzira yezvakasikwagasi bhora mavharuvhu, kunyanya trunnion ball valves, inokosha kune yakachengeteka uye inobudirira kuendesa gasi rechisikigo. Sezvo kune marudzi maviri makuru emagadzirirwo ezvigaro zvevharuvhu: resilient uye simbi, mainjiniya anofanirwa kunyatsoongorora izvo zvinodiwa zvekushandisa kwavo kusarudza mhinduro yakakodzera. Nekunzwisisa mashandiro uye dhizaini yekufunga kweaya mavharuvhu, vashandisi vanogona kuve nechokwadi chekuvimbika kwemapombi egasi chaiwo uye kubatsira mukuchengetedzeka kwese kweindasitiri yesimba.
