Kungekudala, kwi-workshop ye-Jinbin, i-batch ye-200 × 200 iivalve zesango lesilayidi sele ipakishwe kwaye yaqala ukuthunyelwa. Okuivalve yesango yesilayidiyenziwe ngentsimbi yekhabhoni kwaye ixhotyiswe ngamavili entshulube yezandla.

Ivalve yesango lesilayidi sesilayidi sisixhobo sevalvu eqonda ulawulo lokucinywa kwesixhobo ngokusebenza ngesandla. Ubume bayo obungundoqo bubandakanya umzimba wevalvu, ipleyiti yesango, ivili lesandla kunye nendlela yokuhambisa. Umzimba wevalvu ubukhulu becala wenziwe ngezinto ezinganxibiyo ezifana nentsimbi, intsimbi yekhabhoni okanye intsimbi engatyiwa. Umphezulu weplate yesango icutshungulwe ngokuchanekileyo okanye ifakwe kwiilayini zokunxiba, ezinokuthi zilungelelanise indawo yokuhambisa yeendaba ezahlukeneyo. Xa kuthelekiswa neevalve zesango zombane okanye zomoya, iimveliso zezandla zineempawu zesakhiwo esincinci, ukufakwa okufanelekileyo kunye neendleko eziphantsi zokugcinwa, kwaye zifaneleke ngokukodwa kwiinkqubo zemibhobho ezincinci kunye neziphakathi okanye iimeko ezineemfuno eziphantsi zokuzenzekelayo.

Ngokubhekiselele kwiimpawu ezisebenzayo, iingenelo eziphambili zamasango ezilayidi ze-manual zibonakaliswa kwimilinganiselo emithathu: Okokuqala, banomsebenzi obalaseleyo wokutywinwa. Umphezulu woqhagamshelwano phakathi kwesango kunye nomzimba wevalvu wamkela ukutywinwa kwerabha okanye uyilo lokutywina oluqinileyo lwentsimbi, olunokuthi luthintele ngokufanelekileyo ukuvuza kothuli, izixhobo zegranular kunye nolwelo oludlekayo, kunye noxinzelelo lokutywina oluzinzileyo lunokufikelela ngaphezulu kwe-0.6MPa. Okwesibini, inako ukukwazi ukulungelelanisa isantya sokuhamba. Ngokulawula ukuphakama kweplate yesango yokuphakamisa kunye nokwehliswa, izinga lokuhamba eliphakathi linokulawulwa ngaphakathi koluhlu lokuvula lwe-10% ukuya kwi-90%, ukuhlangabezana neemfuno zokulawula izinto ezihambisa isantya kwimveliso yoshishino. Okwesithathu, umsebenzi wokuvala ukhuseleko uthembekile. Xa ivalwe ngokupheleleyo, inokumelana noxinzelelo olusebenzayo lwenkqubo yombhobho, ukuqinisekisa ukhuseleko lokugcinwa kwezixhobo okanye ukuphatha iimpazamo kunye nokukhusela iingozi zemveliso ezibangelwa ukubuya okuphakathi.

Kwizicelo ezisebenzayo, ukukhethwa kweevalve zesango lesilayidi esizilayidi kufuneka kumiselwe ngokubanzi ngokusekelwe kwiiparameters ezifana neempawu ze-medium (ubushushu, ubungakanani bamasuntswana, ukubola), ububanzi bombhobho (DN50-DN1000), kunye noxinzelelo lokusebenza. Ngokomzekelo, xa uphethe izinto eziphezulu ze-viscosity, idizayini yeplate yesango yobubanzi obukhulu kufuneka ikhethwe ukukhusela ukunamathela kwezinto kunye nokuvala. Ukuthuthwa kwezinto zokutya, insimbi engenasici kufuneka isetyenziswe kwaye i-mirror-polished ukuhlangabezana nemigangatho yococeko. Ukusetyenziswa kwansuku zonke, ukusetyenziswa rhoqo kwegrisi kwindlela yokuhambisa kunye nokucoca i-debris ukusuka kumphezulu weplate yesango kunokwandisa kakhulu ubomi bayo benkonzo kunye nokuqinisekisa ukusebenza okuzinzile kwexesha elide.

Iivalvu ze-Jinbin zenze iivalvu ezahlukeneyo ezikumgangatho ophezulu kwiminyaka engama-20 (abavelisi beValve yesilayidi seSango). Ukuba unazo naziphi na iimfuno ezinxulumeneyo, nceda uqhagamshelane nathi ngezantsi kwaye uya kufumana impendulo kwiiyure ezingama-24! (Ixabiso leValve yeSango lesilayidi)
