Kutshanje, kwi-workshop yaseJinbin, iqela leevalvu zesango lesilayidi ezingama-200×200 lipakishwe kwaye laqala ukuthunyelwa.ivalvu yesango lesilayidiyenziwe ngentsimbi yekhabhoni kwaye ixhotyiswe ngamavili eempethu asetyenziswa ngesandla.

Ivalvu yesango lesilayidi esetyenziswa ngesandla sisixhobo sevalvu esilawula indlela yokuvula kwesixhobo ngokusebenzisa indlela yokusebenza ngesandla. Ulwakhiwo lwayo oluphambili luquka umzimba wevalvu, ipleyiti yesango, ivili lesandla kunye nendlela yokudlulisela. Umzimba wevalvu wenziwe kakhulu ngezinto ezingagugiyo ezifana nentsimbi ephosiweyo, intsimbi yekhabhoni okanye intsimbi engatyiwayo. Umphezulu wepleyiti yesango ucutshungulwa ngokuchanekileyo okanye ugqunywe ngee-liners ezingagugiyo, ezinokuzivumelanisa nemeko yokuhambisa yemidiya eyahlukeneyo. Xa kuthelekiswa neevalvu zesango zombane okanye zomoya, iimveliso ezenziwe ngesandla zineempawu zesakhiwo esincinci, ukufakelwa okulula kunye neendleko zokulungisa eziphantsi, kwaye zifanelekile ngakumbi kwiinkqubo zepayipi ezincinci neziphakathi okanye iimeko ezineemfuno eziphantsi zokwenza izinto ngokuzenzekelayo.

Ngokuphathelele iimpawu zokusebenza, iingenelo eziphambili zeegeyithi zesilayidi ezenziwe ngesandla zibonakala kwiinkalo ezintathu: Okokuqala, zisebenza kakuhle kakhulu ekutywineni. Umphezulu woqhagamshelwano phakathi kwegeyithi kunye nomzimba wevalvu usebenzisa uyilo lokutywina irabha okanye uyilo lokutywina oluqinileyo lwesinyithi, olunokuthintela ngempumelelo ukuvuza kothuli, izinto ezibumdaka kunye nolwelo olubolayo, kwaye uxinzelelo lokutywina olungaguqukiyo lunokufikelela ngaphezulu kwe-0.6MPa. Okwesibini, inamandla okulungisa isantya sokuhamba. Ngokulawula ukuphakama kokuphakamisa nokwehlisa kwepleyiti yegeyithi, isantya sokuhamba esiphakathi sinokulawulwa ngaphakathi koluhlu lokuvula lwe-10% ukuya kwi-90%, ukuhlangabezana neemfuno zokulawula isantya sokuhambisa izinto kwimveliso yemizi-mveliso. Okwesithathu, umsebenzi wokuvala ukhuseleko uthembekile. Xa uvaliwe ngokupheleleyo, unokumelana noxinzelelo olusebenzayo lwenkqubo yepayipi, ukuqinisekisa ukhuseleko lokugcinwa kwezixhobo okanye ukuphathwa kweempazamo kunye nokuthintela iingozi zemveliso ezibangelwa kukubuyela umva okuphakathi.

Kwizicelo ezisebenzayo, ukukhethwa kweevalvu zesango lesilayidi esisetyenziswa ngesandla kufuneka kumiselwe ngokupheleleyo ngokusekelwe kwiiparameter ezifana neempawu zendlela ephakathi (ubushushu, ubungakanani besuntswana, ukubola), ububanzi bepayipi (DN50-DN1000), kunye noxinzelelo lokusebenza. Umzekelo, xa kuphathwa izinto ezixineneyo kakhulu, uyilo lwepleyiti yesango enobubanzi obukhulu kufuneka lukhethwe ukuthintela ukunamathela kunye nokuvaleka kwezinto. Ukuthutha izinto ezikumgangatho wokutya, intsimbi engatyiwayo kufuneka isetyenziswe kwaye ipolishwe ngesipili ukuze ihlangabezane nemigangatho yococeko. Ekusetyenzisweni kwemihla ngemihla, ukufaka igrisi rhoqo kwindlela yokudlulisa kunye nokucoca inkunkuma kumphezulu wepleyiti yesango kunokwandisa kakhulu ubomi bayo benkonzo kwaye kuqinisekiswe ukusebenza okuzinzileyo kwexesha elide.

I-Jinbin Valves ibisoloko isenza iivalvu ezahlukeneyo zoshishino ezikumgangatho ophezulu kangangeminyaka engama-20 (Abenzi beeValve zeSango leSlide). Ukuba uneemfuno ezinxulumene noko, nceda unxibelelane nathi ngezantsi kwaye uya kufumana impendulo kwiiyure ezingama-24! (Ixabiso leValve yeSango leSlide)
