I-plug-in ehlengahlengiswayo yokujonga uxinzelelo lwevalvu ye-DLF08-00

Ivalve yesango yevalve yokukhulula ibhekisa kwivalve yesango evalayo (isango) kwaye ihamba ngokuthe nkqo ecaleni komgca osembindini wetshaneli. Ivalve yesango isetyenziselwa ukuqhawula umbhobho. Ivalve yesango yivalve yesango esetyenziswa ngokubanzi. Ngokuqhelekileyo isetyenziselwa izixhobo ze-truncation kunye ne-DN≥50 mm .. Ngamanye amaxesha, iivalve zesango nazo zisetyenziselwa izixhobo ezincinci zokusika. Iivalvu zesango zinezi nzuzo zilandelayo: ① Isithintelo solwelo esincinane. ② Amandla angaphandle afunekayo ukuvula nokuvala ivalve yokunceda esebenza ngokuthe ngqo incinci. (3) ulwalathiso lwezinto eziphathekayo aluthintelwanga. (4) xa ivuleke ngokupheleleyo, umphezulu wokutywina awurhawuki kancinane zizinto ezisebenzayo kunevalve esikiweyo. ⑤ Umfanekiso ulula kakhulu kwaye inkqubo yokubumba ilungile. Iivalvu zesango nazo zineziphene: ① Umphakamo onxulumeneyo kunye neqondo lokuvula likhulu kakhulu. Indawo yangaphakathi efunekayo yokuhlanganisa sikhulu. ② Ngethuba lokuvula kunye nokuvala umsebenzi, kukho ukungqubuzana phakathi kweendawo zokutywina, ekulula ukubangela ukungqubuzana. ③ Iivalvu zesango zinemigangatho emibini yokutywina, ekunzima ukuyivelisa, ukuyiqhuba, ukucola nokuyigcina. Iivalve zesango zinokwahlulwa zibe: (1) iivalve zesango ezinxuseneyo: iindawo zokutywina zihambelana ne-axis ethe nkqo, oko kukuthi, iindawo zokutywina ezimbini zihambelana enye kwenye. Kwiivalvu zesango ezinxuseneyo, isakhiwo esine-thrust wedge sixhaphake kakhulu, oko kukuthi, kukho iiweji ezimbini ze-thrust phakathi kwamasango amabini. Le valve yesango ifanelekile kwiivalve zesango ezinobubanzi obuncinci (DN40-300mm) kwi-voltage ephantsi. Kukwakho nepleyiti yasentlakohlaza phakathi kweenkunzi zeegusha ezimbini, kwaye umthombo we-torsion unokubangela amandla okuqinisa kwangaphambili, okuluncedo ekutywinweni kwepleyiti yevalve yoncedo lombane. (2) Ivalve yesango leWedge: umphezulu wokutywina wenza i-engile ethile ene-axis ethe nkqo, oko kukuthi, iindawo ezimbini zokutywina zenza ivalve yesango elisikere. I-oblique yokujonga i-angles yendawo yokutywina ngokubanzi i-2 52', 3 30', 5, 8, 10, njl njl. Isitshixo kwi-angle yiqondo lokushisa kwezinto. Ngokubanzi, okukhona iqondo lobushushu liphezulu, kokukhona i-engile yokubukela kufuneka ibe yeyokunciphisa amathuba okutshata xa ubushushu butshintsha.
