Vharuvhu yebhoraivharuvhu yekudzora mvura, uye chimiro chayo chikuru uye musimboti ndeizvi:
Vharuvhu yebhoraTsanangudzo uye musimboti wekushanda
Muviri wevharuvhu yebhora wakaita sedenderedzwa, une buri pakati, uye bhora rakaiswa pakati pezvigaro zvevharuvhu mumuviri wevharuvhu. Nekutenderedza bhora revharuvhu nemadhigirii makumi mapfumbamwe, rinogona kuvharira mvura dzakadai semvura kana magasi uye kuvhara nzira yekuyerera. Saka, musimboti wevharuvhu yebhora ndewekudzora kuvhurwa kwemvura nekutenderedza bhora. Zvikuru, kana mubato kana dhiraivha ichitenderera, tsinde yevharuvhu inotyaira bhora kuti ritenderere, nokudaro ichichinja chimiro chechiteshi mumuviri wevharuvhu uye kuona kudzora kwemvura.
Vharuvhu yebhoraZvimiro zvechivako
Zvinhu zvikuru zvevharuvhu rebhora zvinosanganisira bhora, chigaro chevharuvhu, hunde yevharuvhu, uye mubato (kana kuti drive). Pakati pazvo, chigaro chevharuvhu chinowanzogadzirwa nezvinhu zvinonamira kuti ive nechokwadi chekuti vharuvhu ine mashandiro akanaka ekuvhara kana yakavharwa. Kana bhora richitenderera kuti ribate chigaro chevharuvhu, nekuda kwekusimba kwechigaro chevharuvhu, chisimbiso chinogona kugadzirwa kudzivirira kubuda kwemvura. Bhora rinogona kutenderera zvakasununguka mumuviri wevharuvhu kudzora kuvhurwa kwemvura.
Pamusoro pezvo, muviri wevharuvhu yevharuvhu yebhora une mhando mbiri: muviri wakazara nehafu yebhora. Chimiro chinoyangarara ndechekuti bhora rakasungirirwa uye rinotsigirwa nechigaro chevharuvhu chakaiswa mumuviri wevharuvhu, icho chinowanzo shandiswa pakumanikidzwa kwakaderera uye dhayamita diki. Rudzi rwe trunnion rune chimiro chinotenderera, chikamu chepamusoro chebhora chinotsigirwa nehunde yevharuvhu, uye chikamu chepazasi chinotsigirwa ne trunnion, iyo inowanzo shandiswa pakumanikidzwa kwakakwirira uye dhayamita hombe.
Vharuvhu yebhoraMhando uye kupatsanura
Zvichienderana nemaumbirwo akasiyana uye mashandisirwo, mavharuvhu ebhora anogona kukamurwa kuita mhando dzakasiyana. Semuenzaniso:
Trunnion Yakaiswa Ball Valve
Bhora rakagadzika uye harifambi mushure mekumanikidzwa, kazhinji nechigaro chevharuvhu chinoyangarara.
Inoyangarara Ball Valve
Bhora richadzvanywa zvakasimba pamusoro pechisimbiso chegomba rekubuditsa mvura pasi pekumanikidzwa kwechinhu chepakati kuti chive nechokwadi chekuti gomba rekubuditsa mvura rakavharwa.
Vharuvhu yebhora ine nzira nhatu
Bhora rine chimiro chakaita seT kana kuti L rinogona kuona kupatsanurwa uye kusangana kwemvura.
Vharuvhu yebhora inodziya zvakanyanya
Bhora nechigaro chevharuvhu zvinowanzogadzirwa nezvinhu zvinodzivirira kupisa kwakanyanya uye zvinogona kushanda zvakanaka munzvimbo dzinopisa zvakanyanya.
Vharuvhu yebhora ine kumanikidzwa kwakanyanya
Bhora nechigaro chevharuvhu zvinowanzogadzirwa nezvinhu zvinodzivirira kumanikidzwa kwakanyanya uye zvinogona kushanda zvakajairika munzvimbo dzine kumanikidzwa kwakanyanya.
Pamusoro pezvo, inogonawo kupatsanurwa zvichienderana nenzira yekutyaira (yakadai seyemaoko, yepneumatic, yemagetsi, nezvimwewo), nzira yekubatanidza (yakadai sekubatanidza flange, kubatana kweshinda, kubatana kwewelding, nezvimwewo) uye zvinhu (zvakadai sesimbi, zvinhu zvisiri zvesimbi, nezvimwewo).
Vharuvhu yebhoraBasa uye mashandisirwo
Mavharuvhu ebhora ane hunhu hwekuva nyore, kuvharwa zvakanaka uye kushanda zviri nyore. Anoshandiswa zvakanyanya mumafuta, makemikari, simbi, magetsi, mvura yepombi, gasi rechisikigo nedzimwe nzvimbo dzeindasitiri. Anogona kushandiswa kudzora kuyerera kwemvura uye kuona hutsanana nekuchengetedzeka kwenzvimbo yekugadzira. Panguva imwe chete, mavharuvhu ebhora akakodzerawo kune akasiyana-siyana media uye gasi-solid uye liquid-solid two-phase flows, uye ane mikana yakakura yekukura.
Kugadzirisa nekutarisira
Kuti vharuvhu yebhora ishande zvakanaka kwenguva yakareba, panodiwa kugadziriswa nguva dzose uye kutarisirwa. Matanho chaiwo anosanganisira:
1. Gara uchitarisa muviri wevharuvhu nedanda revharuvhu kuti uone kana paine zviratidzo zvekuora, kutsemuka kana kumwe kukuvara.
2. Tarisa mashandiro evharuvhu kuti ive nechokwadi chekuti hapana kubuda kwemvura.
3. Pamavharuvhu ebhora anoshandiswa nemaoko, gara uchizora mafuta pamudzi wevharuvhu nebhokisi remagiya kuti uderedze kupera.
4. Chengeta kunze kwevharuvhu yebhora kwakachena uye bvisa guruva nemafuta; kana zvichibvira, chenesa vharuvhu yebhora nechigaro chevharuvhu nguva nenguva kudzivirira tsvina kuti isaungane.
5. Tarisa kana zvese zvinosungirirwa (zvakaita semasikuruu nenzungu) zvakasununguka wozvisimbisa nenguva.
Muchidimbu
Vharuvhu yebhora imhando yevharuvhu inoshanda uye yakavimbika inoita basa rakakosha mumabasa akasiyana-siyana emaindasitiri. Kuburikidza nekuisa, kushandisa uye kugadzirisa nemazvo, kushanda kwakasimba kwevharuvhu yebhora kunogona kuve nechokwadi uye hupenyu hwayo hwekushanda hunogona kuwedzerwa.
