Iivalvu zensimbi ezingenasici zifaneleke kakhulu ukusetyenziswa kwimibhobho eyonakalisayo kunye nemibhobho yomphunga. Zineempawu zokumelana ne-corrosion, ukumelana nobushushu obuphezulu kunye nokumelana noxinzelelo oluphezulu. Ngokuqhelekileyo zisetyenziswa kwimibhobho eyonakalisayo kwizityalo zemichiza, kunye nemibhobho yamanzi epompo okanye kwizityalo zokutya. Izivalo zentsimbi yekhabhoni azikwazi ukumelana nomhlwa kwaye zinokusetyenziswa kuphela kwimibhobho ephakathi engadlekiyo efana nomphunga, i-oyile, amanzi, njalo njalo. imibhobho isetyenziswa. Intsimbi yekhabhoni isetyenziswa, kwaye iivalvu zentsimbi engatyiwayo kunye nezinye izinto zisetyenziselwa ukubola. Oku kulandelayo yinkcazo emfutshane yokukhethwa kwesicelo se-valve yensimbi engenastainless kunye ne-carbon steel gate valve yi-NSW Valve:
1 Yintoni isizathu sokuvuza kwevalve yensimbi ye-carbon
Ivalve yentsimbi yentsimbi yeCarbon yivalve yoshishino, esetyenziswa kakhulu kwipetroleum, kwikhemikhali, kwisikhululo samandla nakwamanye amashishini. Inoncedo lokuzenzekelayo, ukusebenza lula, kunye nobomi benkonzo ende, kodwa xa usebenzisa
Ngethuba lenkqubo, ngenxa yempembelelo ngokwayo okanye izinto zangaphandle, i-valve yesango ye-carbon steel iya kuvuza. Ngoko ke, yintoni isizathu sokuvuza kwevalve yesango lentsimbi yecarbon? Iingongoma eziphambili zezi zilandelayo
izizathu eziqhelekileyo.
1. Ukuchaneka okuphantsi kokulungiswa komsesane wokutywina omise okwe-wedge kukhokelela ekuvuzeni kwangaphakathi kwevalve yesango lentsimbi ye-carbon. Logama nje ivalve yesango yophawu olukhulu ikhethiwe, umgangatho weendawo ezisecaleni ungcono kakhulu, ukwenzela ukuba ukuchaneka kokusetyenzwa komsesane wokutywina kungabi phantsi.
1. Imveliso engazinzanga kunye neemeko zokusebenza zikhokelela ekuvuzeni kwangaphakathi kwe-valve yesango. Ivalve yesango ineemfuno eziphezulu kakhulu kwindawo yokusebenza. Ukuba uxinzelelo kunye neqondo lokushisa lizinzile kwaye uluhlu lwenguqu lukhulu kakhulu, uxinzelelo lwempembelelo kwindandatho yokutywina luya kuba lukhulu, olulula kakhulu. Utshintsho lwenzeka, olukhokelela ekugqibeleni ekuvuzeni kwevalvu.
3. Umgangatho ophantsi wokugcinwa kwevalve ukhokelela ekuvuzeni kwangaphakathi kwevalve yesango. Abanye abasebenzi abawucoci umphezulu wokutywina weringi yokutywina xa belungisa ivalve. Ubukho bokungcola buya kuchaphazela ukusebenza kwevalve. Ekuhambeni kwexesha, umphezulu wokutywina uya kukrweleka, okuya kubangela ukuvuza kwevalve.
4. Iringi yokutywina emise okwe-corrosion yekhaka ibangela ukuba ivalve yesango ivuze ixesha elide. Ngaphantsi kwefuthe eliphakathi, umsesane wokutywina unqanyulwa lula. Ukuba umhlwa ufikelela kwinqanaba elithile, umsesane wokutywina uya kuxelwa, ukuze ivalve ivuze.
5. Umzimba wevalvu uneziphene. Ukuba umzimba we-valve uneengxaki ezifana ne-pores, i-slag inclusions, i-cracks, imingxuma yesanti, njl., Ke i-valve yesango ilungele ukuvuza kwangaphandle ngexesha lokusetyenziswa.
Ngamafutshane, ukuvuza kwevalve yesango yentsimbi yingxaki eqhelekileyo. Ukuba kukho ukuvuza, kuya kubeka engozini ukhuseleko lwezixhobo kunye nabasebenzi, ngoko ke kuyimfuneko ukufumanisa isizathu kunye nokusombulula ingxaki ngexesha.
4 Indlela yokukhetha ivalve yentsimbi ethembekileyo
Ngokwahlukileyo kwivalve yebhola ye-pneumatic eqhelekileyo, ivalve yebhabhathane yombane kunye nezinye izixhobo zevalve, ukuveliswa kwesango akufuneki kuhlengahlengise ukuhamba kolwelo olumileyo, kodwa lusebenza luvuleke ngokupheleleyo kwaye lunqunyulwe ngokupheleleyo kumbhobho.
Isango lokutshintsha lisetyenziswa. Ngoko kukho iivalvu zesango zentsimbi ezingenasici kwimarike, yeyiphi imveliso ethembekileyo? Iimpawu zeevalvu zesango zensimbi engenasici
Insimbi engenasici yenziwe ngentsimbi engenanto. I-high-quality steel stainless kunye nonyango oluphezulu kunye nokucinywa kunye nokufudumeza okutshintshileyo kwenza insimbi engenasici ibe yindawo efanelekileyo yokuchasana nokubola kunye nomgangatho omhle.
I-Abrasion, yomelele kakhulu. Ngoko ke, i-valve yesango yensimbi engenasici isoloko isetyenziselwa ukulawula ukuhamba kweekhemikhali, kwaye ukutywinwa kwayo kakuhle kunye nokumelana nokubola kwenza ukuba kungabi lula ukuchithwa kunye nokuhlanjwa yi-medium.
Ubushushu obuphezulu kunye noxinzelelo oluphezulu indoda inokuqinisekisa ukusebenza kakuhle kokutywinwa. Yeyiphi ivalve yesango yentsimbi engenasici ingcono
Kuthiwa ivalve yesango yentsimbi engenasici sisixhobo nje sevalvu yeshishini, kodwa eneneni ijongwe kakhulu. Ngokomzekelo, ukuba ukhetho lwevalve yesango lungalunganga, iingozi ezingalindelekanga zingenzeka, ngoko musa
Ivalve yesango yensimbi engenasici kufuneka ivavanywe uxinzelelo ngaphambi kokuba iphume kumzi-mveliso. Xa kuthengwa i-valve, umthengi kufuneka anqume uluhlu loxinzelelo olufunekayo ukuba i-valve ixhathise kwangaphambili ukukhetha imodeli efanelekileyo kunye neenkcukacha.
Abavelisi abaqhelekileyo bangqongqo kwaye bechanekile ekuvavanyeni uxinzelelo, ngoko ke nokuba ngaba umgangatho wevalve, ubomi benkonzo, ukuphumelela kweendleko, okanye ukusebenza kokhuseleko.
Kubaluleke kakhulu ukukhetha umenzi oqhelekileyo kunye nothembekileyo, kwaye iimveliso zabakhiqizi abaqhelekileyo (i-NSW Valve) zikhuselekile ngakumbi.
Umthengi ngamnye uneemfuno ezahlukeneyo zeevalvu zesango lentsimbi eyomileyo. Ngokubhekiselele kwixabiso, umgangatho kunye nokukhusela uphawu, abavelisi abahlukeneyo ngamanye amaxesha banokwahlukana okucacileyo. Ke ngoko, ukhetho lwabavelisi kufuneka luqwalasele izinto ezahlukeneyo.
