Ivalve yebhabhathane eneswitshi ye tamperluhlobo lwevalve yokulawula ukuhamba esetyenziswa ngokuyinhloko kwiinkqubo zokukhusela umlilo kunye nezicelo zoshishino. Idibanisa ukusebenza kwevalve yebhabhathane kunye nokhuseleko olongezelelweyo lokutshintsha kwe-tamper, okwenza kube lula kwiimeko apho zombini ukulawulwa kokuhamba kunye nokubeka iliso kubaluleke kakhulu.
Ivalve yebhabhathane
Ivalve yebhabhathane yivalve yokujika kwekota elawula ukuhamba kolwelo kumbhobho. Ivalve iqukethe idiski ejikelezayo, ebizwa ngokuba yi "butterfly," ejikeleza i-axis. Xa i-valve ikwindawo evuleke ngokupheleleyo, i-disc ilungelelaniswe ngokuhambelana nokuhamba, ivumela ukugqithisa kwamanzi amaninzi. Kwindawo evaliweyo, i-disc ijikeleza i-perpendicular to flow, ivimba i-passage ngokupheleleyo. Olu luyilo lusebenza kakuhle kakhulu ekulawuleni umthamo omkhulu wolwelo kunye nokulahleka koxinzelelo oluncinci kwaye lusetyenziswa ngokuqhelekileyo kwiinkqubo ezifuna ukuvulwa nokuvala ngokukhawuleza.
Iivalve zebhabhathane zaziwa ngoyilo lwazo olubambeneyo, ulwakhiwo olukhaphukhaphu, kunye nokusebenziseka ngokulula. Zisetyenziswa kumashishini ahlukeneyo afana nokunyanga amanzi, ukusetyenzwa kweekhemikhali, kunye nokukhusela umlilo.
Ukutshintsha kweTamper
Ukutshintsha kwe-tamper sisixhobo sombane esibeka iliso kwindawo yevalve kunye nemiqondiso ukuba ukuguqulwa okungagunyaziswanga okanye utshintsho kwindawo yevalve. Kwiinkqubo zokukhusela umlilo, kubalulekile ukuqinisekisa ukuba iivalvu ezilawula ukuhamba kwamanzi zihlala kwindawo yazo efanelekileyo (ngokuqhelekileyo zivulekile, ukuvumela amanzi ukuba aqhube ngokukhululekile xa kukho umlilo). Ukutshintsha kwe-tamper kunceda ukuqinisekisa oku ngokuthumela isilumkiso ukuba i-valve isusiwe kwindawo yayo ekujoliswe kuyo-mhlawumbi ngabom okanye ngengozi.
Iswitshi ye-tamper idla ngokuba neengcingo kwiphaneli yokulawula ialam yomlilo. Ukuba umntu uzama ukuvala okanye ukuvala i-valve yebhabhathane ngaphandle kokugunyaziswa, inkqubo ibona ukunyakaza kwaye ibangele i-alamu. Olu phawu lokhuseleko lunceda ukuthintela ukungasebenzi kakuhle kwenkqubo, ukuqinisekisa ukuba inkqubo yokucima umlilo ihlala isebenza xa ifuneka.
Ukusetyenziswa kuKhuseleko loMlilo
Iivalve zebhabhathane ezinezitshixo ze-tamper zisetyenziswa kakhulu kwiinkqubo zokukhusela umlilo ezifana neenkqubo zokufafaza, ii-standpipes, kunye neepompo zomlilo. Ezi nkqubo zixhomekeke kubukho obungaguqukiyo bamanzi ukulawula okanye ukucima imililo. Ivalve yebhabhathane kwezi nkqubo idla ngokugcinwa kwindawo evulekileyo, kwaye i-tamper switch iqinisekisa ukuba ihlala injalo ngaphandle kokuba ukugcinwa okanye inkqubo egunyazisiweyo iyenzeka.
Ngokomzekelo, kwisixokelelwano sokutshiza umlilo, ukuba ivalve yebhabhathane ibivalwa (nokuba kungenxa yengozi okanye i-sabotage), ukuhamba kwamanzi kwizitshizi kuya kunqunyulwa, nto leyo eyenza inkqubo ingasebenzi. Isixhobo sokutshintsha i-tamper sisebenza njengokhuselo kwimingcipheko enjalo ngokuvula i-alam kwimeko apho ivalve ithe yaphazamiseka, oko kukhokelela ekubeni kuqwalaselwe ngokukhawuleza kubaphathi beziko okanye kubasebenzi bakaxakeka.
Iingenelo
l Ukhuseleko: I-tamper switch yongeza umaleko owongezelelweyo wokukhusela ngokuqinisekisa ukuba nayiphi na intshukumo yevalve engagunyaziswanga ibonwa ngokukhawuleza.
l Ukuthembeka: Kwiinkqubo zokukhusela umlilo, ukuthembeka kubaluleke kakhulu. Ukutshintsha kwe-tamper kwandisa ukuthembeka kwenkqubo ngokuqinisekisa ukuba ivalve isoloko ikwindawo echanekileyo.
l Ukubeka iliso olulula: Ngokudibanisa neenkqubo ze-alamu zomlilo, ukutshintshwa kwe-tamper kukuvumela ukubeka iliso elikude le-valve status, okwenza kube lula kubaqhubi ukuba bajonge iinkqubo ezinkulu.
l Ukuthobela: Iikhowudi ezininzi zomlilo kunye nemimiselo zifuna ukusetyenziswa kokutshintsha kwe-tamper kwiivalvu zokulawula ukuqinisekisa ukuthotyelwa kwemigangatho yokhuseleko.
Ukuqukumbela
Ivalve yebhabhathane eneswitshi ye-tamper yinxalenye ebalulekileyo yokhuseleko lomlilo kunye neenkqubo zoshishino. Ibonelela ngeendlela ezisebenzayo zokulawula ukuhamba kwamanzi ngelixa uqinisekisa ukhuseleko kunye nokhuseleko ngokusebenzisa amandla okubeka iliso kwi-tamper switch. Ngokudibanisa le mibini imisebenzi, esi sixhobo sinceda ukuthintela ukuphazamiseka okungagunyaziswanga, ukuqinisekisa ukusebenza okuqhubekayo nokuthembekileyo kweenkqubo ezibalulekileyo ezifana neenethiwekhi zokucima umlilo.
