Yenziweivalves kufuneka zenze iimvavanyo ezahlukeneyo zentsebenzo, eyona ibalulekileyo kuzo luvavanyo loxinzelelo. Uvavanyo loxinzelelo kukuvavanya ukuba ixabiso loxinzelelo elinokuthi i-valve likwazi ukumelana neemfuno zemimiselo yokuvelisa.Kwi-TWS, iivalve yebhabhathane ehleli ethambileyo, kufuneka iqhutywe uvavanyo lokuxinwa kwesitulo soxinzelelo oluphezulu. Uxinzelelo oluchazwe ngamaxesha e-1.5 e-PN luya kusetyenziswa kumanzi okuvavanya.
Amagama aphambili:Uvavanyo loxinzelelo;Ivalve yebhabhathane ehleliyo ethambileyo; Uvavanyo lweSitulo soxinzelelo lweSitulo
Ngokuqhelekileyo, uvavanyo loxinzelelo lweiivalvekufuneka ihambelane nale migaqo kunye nezilumkiso zilandelayo:
(1) Ngokubanzi, iivalveayiphantsi kovavanyo lwamandla, kodwa iivalveumzimba kunye nebhonethi emva kokulungiswa okanye iivalveumzimba kunye nebhonethi enomonakalo wokubola kufuneka ivavanyelwe amandla. Kwivalve yokhuseleko, uxinzelelo lwayo oluqhubekayo, uxinzelelo lokuhlaziya kunye nezinye iimvavanyo ziya kuhambelana neenkcukacha zemiyalelo yayo kunye nemimiselo efanelekileyo.
(2) Uvavanyo lwamandla kunye nokuqina kufuneka lwenziwe ngaphambi kokubaivalveifakiwe. I-20% ye-low-pressure valves ihlolwe indawo, kwaye i-100% yazo kufuneka ihlolwe ukuba ayinakufaneleka; I-100% ye-valve ephakathi kunye nephezulu yoxinzelelo kufuneka ihlolwe.
(3) Ngexesha lovavanyo, indawo yofakelo lweivalvekufuneka ibe kwicala apho kulula ukuhlola.
(4) Kubaiivalvengendlela yokudibanisa okudibeneyo, ukuba uvavanyo loxinzelelo lweplate eyimfama alunakusetyenziswa, i-conical seal okanye i-O-ring seal ingasetyenziselwa uvavanyo loxinzelelo. (5) Ungabandakanyi umoya wevalve kangangoko kunokwenzeka ngexesha lovavanyo lwehydraulic.
(6) Uxinzelelo kufuneka lwandiswe ngokuthe ngcembe ngexesha lovavanyo, kwaye ukunyanzeliswa okubukhali kunye nokukhawuleza akuvumelekanga.
7 Ixesha lovavanyo lweevalvu ezinobubanzi obuncinci linokuba lifutshane ngokuhambelanayo, kwaye ixesha lovavanyo lweevalvu ezinobubanzi obukhulu linokuba lide ngokulinganayo. Ngexesha lovavanyo, ukuba uyathandabuza, ixesha lokuvavanya linokwandiswa. Ngexesha lovavanyo lwamandla, ukubila okanye ukuvuza kweivalveumzimba kunye nebhonethi ayivumelekanga. Uvavanyo lokutywinwa lwenziwa kube kanye kuphela jikeleleiivalve, kwaye kabini kwiivalvu zokhuseleko, uxinzelelo oluphezuluiivalvekunye nokunye okubalulekileyoiivalve. Ngethuba lovavanyo, ukuvuza okuncinci kuvunyelwe kwiivalve ezingabalulekanga kunye noxinzelelo oluphantsi kunye nobukhulu obukhulu kunye nezivalo ezinemimiselo yokuvumela ukuvuza; ngenxa yeemfuno ezahlukeneyo zeevalvu eziqhelekileyo, iivalvu zesikhululo samandla, iivalvu zaselwandle kunye nezinye iivalvu, iimfuno zokuvuza kufuneka zibe ngolu hlobo lulandelayo: Yenza ngokwemigaqo efanelekileyo.
(8) I-valve ye-throttle ayixhomekeke kuvavanyo oluqinileyo lwecandelo lokuvala, kodwa uvavanyo lwamandla kunye novavanyo lokuqina lokupakisha kunye ne-gasket kufuneka lwenziwe. (9) Ngethuba lovavanyo loxinzelelo, amandla okuvala i-valve avunyelwe kuphela ukuvalwa ngamandla aqhelekileyo omzimba womntu omnye; akuvumelekanga ukusebenzisa amandla ngezixhobo ezifana ne-levers (ngaphandle kwe-torque wrench). Xa ububanzi be-handwheel bukhulu okanye bulingana ne-320mm, abantu ababini bavumelekile ukuba basebenze kunye. ukuvalwa.
(10) Kwiivalvu ezinetywina eliphezulu, ukupakishwa kufuneka kukhutshelwe ukuvavanya ukuqina. Emva kokuba itywina eliphezulu livaliwe, khangela ukuvuza. Xa usebenzisa igesi njengovavanyo, khangela ngamanzi kwibhokisi yokufaka izinto. Xa usenza uvavanyo lwe-tightness yokupakisha, isitywina esiphezulu asivumelekanga ukuba sibe kwindawo eqinile.
(11) Nasiphi na isivalo esinesixhobo sokuqhuba, xa sivavanya ukuqina kwayo, isixhobo sokuqhuba kufuneka sisetyenziswe ukuvala isivalo nokwenza uvavanyo lokuqina. Kwisixhobo esiqhutywa ngesandla, uvavanyo lokutywinwa kwevalve evaliweyo ngesandla luya kwenziwa.
(12) Emva kovavanyo lwamandla kunye novavanyo lokuqina, ivalve yokudlula efakwe kwivalve ephambili iya kuvavanywa amandla kunye nokuqina kwivalve ephambili; xa indawo yokuvala yevalve engundoqo ivuliwe, nayo iya kuvulwa ngokufanelekileyo.
(13) Ngexesha lovavanyo lwamandla ezivalo zentsimbi, cofa umzimba wevalve kunye nesigqubuthelo sevalvu ngentsimbi yobhedu ukujonga ukuvuza.
(14) Xa ivalve ivavanywa, ngaphandle kweevalvu zeplagi ezivumela umphezulu wokutywina ukuba ufakwe i-oyile, ezinye iivalvu azivumelekanga ukuba zivavanye umgangatho wokutywina ngeoyile.
(15) Ngexesha lovavanyo loxinzelelo lwevalvu, amandla okucinezela ipleyiti eyimfama kwivalve akufuneki abe mkhulu kakhulu, ukuze uthintele ukuguqulwa kwevalve kwaye kuchaphazele isiphumo sovavanyo (ukuba ivalve yentsimbi icinezelwe kakhulu. , iya konakaliswa).
(16) Emva kokuba uvavanyo loxinzelelo lwevalvu lugqityiwe, amanzi aqokelelweyo kwivalve kufuneka asuswe ngexesha kwaye acinywe, kwaye irekhodi yovavanyo kufuneka yenziwe.
In Ivalve ye-TWS, Ngokubhekiselele kwimveliso yethu ephambili, ivalve yebhabhathane ehleliyo ethambileyo, kufuneka iqhutywe kuvavanyo lokuxinana kwesitulo soxinzelelo oluphezulu. Kwaye indawo yokuvavanya ngamanzi okanye igesi, kwaye ubushushu bomgangatho wovavanyo buphakathi kwe-5℃~40℃.
Kwaye olu vavanyo lulandelayo kukuqina kweqokobhe kunye nokusebenza kwevalvu.
Injongo yalo kukuba uvavanyo luya kuqinisekisa ukuvuza kokuqina kweqokobhe kuquka indlela yokusebenza yokutywina ngokuchasene noxinzelelo lwangaphakathi.
Ngexesha lenkqubo yovavanyo, kufuneka siqaphele ukuba ulwelo lovavanyo luya kuba ngamanzi.
Kwaye i-disc yevalve iya kuba kwindawo evulekileyo ngokuyinxenye.Isiphelo sokudityaniswa kwevalve siya kucinywa kwaye yonke imingxuma izaliswe ngamanzi ovavanyo. Uxinzelelo oluchazwe ngamaxesha e-1.5 e-PN luya kusetyenziswa kumanzi okuvavanya.
