Ivalve yesango yokutywina ethambileyo, kwaziwa njengeivalve yesango elilastiki lesihlalo, yisivalo esisetyenziswa ngesandla esisetyenziselwa ukudibanisa umbhobho ophakathi kunye nokutshintsha kwiprojekthi yogcino lwamanzi.Ubume beivalve yesango lokutywina elithambileyoyenziwe sisitulo sevalvu, isigqubuthelo sevalvu, ipleyiti yesango, indlala, isiqu, ivili lesandla, igasket kunye nebholithi yehexagon yangaphakathi.Imiphezulu yangaphakathi nangaphandle yejelo lokuhamba kwevalvu ifafazwe ngenkqubo yomgubo we-electrostatic.Emva kokubhakwa kwiziko lobushushu obuphezulu, ukuguda kwawo wonke umlomo wejelo lokuqukuqela kunye negroove emile okwengca ngaphakathi kwevalve yesango kuqinisekisiwe, kwaye imbonakalo ikwanika abantu umbono wombala.Iivalvu zesango ezitywiniweyo ezithambileyozikholisa ukuqaqamba okuluhlaza okwesibhakabhaka kugcino lwamanzi ngokubanzi, kwaye ukukhanya okubomvu-bomvu kusetyenziselwa imibhobho yokukhusela umlilo.Kwaye ngentando yomsebenzisi, kunokutshiwo ukuba ivalve yesango yokutywina ethambileyo sisivalo eyenzelwe ugcino lwamanzi.
Iintlobo kunye nokusetyenziswa kweivalve yesango lokutywina elithambileyo:
Njengevalve yokutshintsha ngesandla eqhelekileyo kumbhobho, iivalve yesango elithambileyoisetyenziswa ikakhulu kwimibhobho yamanzi, imibhobho yogutyulo, iiprojekthi zemibhobho kamasipala, iiprojekthi zemibhobho yomlilo, kunye nemibhobho yoshishino kulwelo olungadleki kancinane neegesi.Kwaye inokwenziwa ngokwemeko yokusetyenziswa kwentsimi, njengeukuphakama kwesiqu esithambileyo sevalve yesango, isikhondo esinganyukiyo ivelufa yesango ethambileyo, intonga eyandisiweyo ivelufa yesango elithambileyo, wangcwatywa ivalve yesango elithambileyo, ivalve yesango yotywino ethambileyo yombane, ivalve yesango yokutywina ethambileyo yepneumatic, njl.
Ziziphi iingenelo zeivalve yesango lokutywina elithambileyo:
1.Iinzuzo zeivalve yesango elithambileyookokuqala kwiindleko zayo, ngokubanzi, uninzi lweuthotho lwevalve yesango lokutywina oluthambileyowamkele i-ductile iron QT450.I-accounting yeendleko ze-valve body iya kufikeleleka kakhulu kuneendleko zetsimbi kunye nentsimbi engenasici.Oku kuyafikeleleka kakhulu xa kuthelekiswa nokuthengwa okuninzi kweprojekthi, kwaye kukwimeko yoqinisekiso lomgangatho.
2.Okwesibini, kwiimpawu zokusebenza zeivalve yesango elithambileyo, ipleyiti yesango yeivalve yesango elithambileyoifakwe irabha elastiki, kwaye ubume bangaphakathi bubunjwe njenge wedge.Kusetyenziso lwesixhobo sevili sesandla esiphezulu, isikrufu siyathotywa ukuqhuba isango elilastiki ukucinezela ezantsi, elivalwe ngomsele wangaphakathi weweji.Ngenxa yokuba isango lerabha elastiki linokwelula kwaye licinezele, ukuze kufezekiswe umphumo wokutywina.Ngoko ke, isiphumo sokutywinwa kweivalve yesango lokutywina elithambileyokugcino lwamanzi kunye nemithombo yeendaba engeyongozi iyabonakala.
3.Ukwenzela ugcino lwakamva lweivalve yesango lokutywina elithambileyo, uyilo lolwakhiwo lweivalve yesango lokutywina elithambileyoilula kwaye icacile, kwaye kulula ukuyichitha kunye nokuyifaka.Xa i-valve isetyenziswe ixesha elide, isango eli-elastic ngaphakathi kwe-valve yesango liya kulahlekelwa u-elasticity ngenxa yokutshintsha rhoqo, kwaye i-rubber iya kulahlekelwa yi-elasticity ixesha elide, okubangela ukuvala i-lax kunye nokuvuza kwe-valve.Ngeli xesha, iingenelo zoyilo lwesakhiwo seivalve yesango etywiniweyoziyabonakaliswa.Abasebenzi besondlo banokuqhaqha ngokuthe ngqo kwaye batshintshe iplate yesango ngaphandle kokususa i-valve yonke.Oku konga ixesha kunye nomzamo kwaye konga abasebenzi kunye nezixhobo eziphathekayo zesiza.
Ziziphi izinto ezingeloncedoivalve yesango lokutywina elithambileyo :
1.Ukuthetha ngeentsilelo zeivalve yesango lokutywina elithambileyo, emva koko sijonge imbono yenjongo.Inqaku eliphambili leivalve yesango lokutywina elithambileyokukuba isango elithambileyo elitywiniweyo linokolulwa kwaye lizaliswe ngokuzenzekelayo.Kuhle kakhulu ukuyisebenzisaivalve yesango lokutywina elithambileyokwirhasi engadlekiyo, ulwelo kunye negesi.
2.Ngokuqinisekileyo, kukho izinto eziluncedo kunye nezingeloncedo.Ukungalungi kweivalve yesango elithambileyokukuba isango lerabha elastiki alinakusetyenziswa ngokuqhubekayo kwiqondo lobushushu elingaphezulu kwama-80 °C okanye ngamasuntswana aqinileyo kunye neemeko ezidlekayo.Ngaphandle koko, isango lerabha elastiki liya konakala, lonakaliswe kwaye lidliwe, okukhokelela ekuvuzeni kwemibhobho.Ngoko ke, i-valve yesango elithambileyo ilungele ukusetyenziswa kuphela kwi-non-corrosive, non-particle, non-wear medium.
Xa ukhetha i-valve, kuyimfuneko ukuqonda iimpawu ze-medium, iqondo lokushisa, uxinzelelo, kunye nokusetyenziswa kwendawo, kudityaniswe nezinto eziluncedo kunye nezingeloncedo.ivalve yesango elithambileyo, uvavanyo olubanzi lwenziwa ukuqhubela phambili ukukhetha i-valve, ukwenzela ukuba i-valve isetyenziswe ngaphandle kokukhathazeka.
