I-stopcock mold sisixhobo esisetyenziswa kwinkqubo yokuvelisa ukuvelisa ii-stopcocks, ezizivalvu ezisetyenziselwa ukulawula ukuhamba kolwelo okanye iigesi kwizicelo ezahlukeneyo, ezifana nezixhobo zonyango okanye izixhobo zelabhoratri.Nazi iindlela ezintathu umngundo we-stopcock osebenza ngayo: Uyilo lokungunda kunye nokuDalwa kweCavity: Ukungunda kwe-stopcock kuyilelwe ukwenza imilo enqwenelekayo kunye nokusebenza kwe-stopcock.Iqukethe iihafu ezimbini okanye ngaphezulu, ngokuqhelekileyo zenziwe ngentsimbi, ezidibana kunye ukuze zenze umngxuma omnye okanye ezininzi apho izinto ezityhidiweyo zitofwa.Uyilo lokungunda lubandakanya iimpawu eziyimfuneko, ezifana nezibuko zokungena neziphumayo, iindawo zokutywina, kunye neendlela zokulawula, ukuqinisekisa ukusebenza ngokufanelekileyo kwesitophucock. Isitofu seMathiriyeli enyibilikisiweyo: Nje ukuba ukungunda kumiselwe kwaye kuvalwe ngokukhuselekileyo, imathiriyeli etyhidiweyo, ngokuqhelekileyo a i-thermoplastic okanye i-elastomeric material, ifakwe kwi-cavities phantsi koxinzelelo oluphezulu.Inaliti yenziwa kusetyenziswa oomatshini abakhethekileyo, abanjengomatshini wokubumba inaliti, onyanzela imathiriyeli ngeetshaneli nakwimingxuma yokungunda.Izinto eziphathekayo zigcwalisa i-cavities, zithatha ubume boyilo lwe-stopcock.Ukupholisa kunokwenziwa lula ngokujikelezisa into yokupholisa ngomngundo okanye ngokusebenzisa iipleyiti zokupholisa.Nje ukuba imathiriyeli yomelele, ukungunda kuyavulwa, kwaye istopcock esigqityiweyo siyakhutshelwa kwimingxuma.Ukukhutshwa kunokufezekiswa ngeendlela ezahlukeneyo, njengezikhonkwane ze-ejector okanye uxinzelelo lomoya.Amanyathelo olawulo lomgangatho, kuqukwa nokuhlolwa kweziphene kunye nokuchaneka komgangatho, anokwenziwa ngeli nqanaba ukuqinisekisa ukuba istopcock siyahlangabezana nemigaqo efunekayo. Lilonke, ukungunda okuyilwe kakuhle kunye nokuveliswa kwe-stopcock ngokuchanekileyo kubalulekile ekuveliseni ii-stopcock ezikumgangatho ophezulu ezisebenza ngokuthembekileyo.I-mold ivumela ukuveliswa ngokufanelekileyo kunye nokuhambelana kwee-stopcocks, ezisetyenziswa ngokubanzi kumashishini ahlukeneyo kwizicelo zokulawula ulwelo.
