I-FDO3-BV3TF-3G (iivelufa zamabhabhathane amancinci amnyama)
Uphawu
Ivelufa yebhabhathane ene-eccentric isetyenziswa ngokubanzi kwisinyithi, amandla ombane, ishishini le-petrochemical, ukuhambisa amanzi kunye nomsele kunye nemibhobho yezokwakha kamasipala enobushushu obuphakathi ≤ 425 ℃ yokulawula ukuhamba nokuhamba kolwelo. Izinto zokwahlulahlulwa: intsimbi yentsimbi, intsimbi yentsimbi kunye nentsimbi engatyiwa
Ukucaciswa kwe-API
Njengoko sonke sisazi, i-API609 iye yaba yinkcazo yamazwe ngamazwe eepayipi ezibalulekileyo zemibhobho. I-Tritec yenzelwe kwaye yenziwa ngokungqinelana nohlelo lwamva nje luka-1997 lwe-API609. Ngaphezu koko, uyilo olusisiseko lweTritec aluphelelanga kwi-API, bs5155, ANSI B 16.34, ASME sec VIII kunye nezinye iinkcukacha eziphambili ezinokuhambelana, eziqinisekisa ukuba iTritec inokusetyenziswa kuwo onke amabakala emizi mveliso.
Ubume bezokhuseleko ezimbini
Ngokuhambelana ngokungqongqo neemfuno zemigaqo ye-API609, ukwenzela ukuthintela ukuvela kwepleyiti yebhabhathane, ukususwa kwesiqu sevalve kunye nokuvaleka komphezulu wokutywina obangelwe yimpembelelo yoxinzelelo lolwelo kunye neqondo lobushushu, iTritec ifake amakhonkco amabini azimeleyo amacala aphezulu nasezantsi epleyiti yamabhabhathane ukuqinisekisa ukusebenza kwesiqhelo kwivelufa phantsi kwazo naziphi na iimeko zokusebenza;
Kwangelo xesha, ukuthintela ingozi ngequbuliso ebangelwe kukuqhekeka kwesivingco kunye nokubhabha ngaphandle kubangelwe zizizathu ezingaziwayo, isiqu esizimeleyo esiphaphazela indlela yothintelo siyilelwe ngaphakathi nangaphandle kwesiphelo esisezantsi sevalve, esiqinisekisa ukuba inqanaba loxinzelelo lweTritec linokufikelela kuma-2500 eepawundi.
Akukho uyilo lommandla ufileyo
Kwinkqubo yoyilo, kuthathelwa ingqalelo ekhethekileyo kwiingxaki zesicelo kwicandelo lolawulo kunye nolawulo. Umgaqo wokutywina wevalvethi e-butterfly eccentric isetyenziswa ngokupheleleyo. Xa ivalve ivuliwe kwaye ivaliwe, ipleyiti yamabhabhathane ayikrwintshi isihlalo sevalve, kwaye i-torque yesitshixo sevalve idluliselwa ngokuthe ngqo kumhlaba wokutywina ngepleyiti yebhabhathane. Ngamanye amagama, akukho kungqubana phakathi kwepleyiti yamabhabhathane kunye nesihlalo sevalve Oku kuthetha ukuba iTritec inokungena kwindawo ehlengahlengiswayo ukusuka ku-0 kuye kuma-90. Umlinganiselo wayo wolawulo oqhelekileyo ungaphezulu kwamaxesha ama-2 kwivalve yamabhabhathane yesiqhelo, kunye nolawulo oluphezulu Umyinge unokuba ngaphezulu kwe-100: 1. Oku kudala iimeko ezilungileyo zokusetyenziswa kweTritec njengevalve yolawulo, ngakumbi kububanzi obukhulu, iindleko ze-valve zokumisa ziphezulu kakhulu, ukongeza, ivelufa yokumisa ayinakufezekisa ukuvuza okunguziro, kwimeko yokucima okungxamisekileyo, Kuyimfuneko ukufakela ivalve evaliweyo kwicala levalve, kwaye iTritec idibanisa ulawulo kunye nokuvala, kwaye izibonelelo zayo zoqoqosho zibaluleke kakhulu.
ulwakhiwo
Isakhiwo esingaphakathi sokumelana nomlilo
Iivalve ezininzi zibanga ukuba zinokwakhiwa okungatshiyo, kodwa uninzi lwazo lisebenzisa isitulo esiqinileyo nesithambileyo sokunciphisa ukuvuza, okuyingozi kakhulu. Ngenxa yokuba ukutsha okungaphelelanga kwesihlalo sevali esitywinileyo emlilweni kuya kwenza ukuba isitulo senkxaso yesinyithi sivelise uxinzelelo kunye nokwahluka kobushushu, nto leyo eya kukhokelela ekusileleni komatshini onganyangekiyo emlilweni. Ke ngoko i-Yurophu kunye ne-United States bayalususa ngokuthe ngcembe olu hlobo lwevalvu enganyangekiyo engafanelekanga ukuba ifumane igama. Ngenxa yokuvuza kwayo okungu-zero, i-tritrc ayilufuni uncedo lwetywina elithambileyo. Sisakhiwo esiyinyani esingatshiyo. Sifumene isiqinisekiso sokumelana nomlilo se-api607, api6fa kunye ne-bs6755part2. Oku kuqinisekisa ukuba iTritec inokusetyenziswa kwioyile, ipetroli kunye nezinye iindawo eziyingozi. Kwi-UK elondolozekayo, apho phantse zonke izivalo ezisetyenziswa kwiindawo eziphambili zeoyile yoLwandle lwaseMantla zigutyungelwe yiTritec, lo ngowona mzekelo mhle.
Ukupakisha okuphezulu
Ngokumalunga nokuvuza kwevalvevu, ngokwesiko, ukuvuza kwesitulo sevalve, okt ukuvuza kwangaphakathi, kuhlala kugxile, ngelixa ukuvuza kwenxalenye yokupakisha kungahoywa, oko kukuthi, ukuvuza kwangaphandle. Ngapha koko, kuluntu lwanamhlanje apho iingxaki zokusingqongileyo zixatyiswa ngakumbi, kuye kwaba yinto engenakuphikiswa ukuba ingozi yokuvuza kwangaphandle inkulu kakhulu kunaleyo yangaphakathi. I-Tritec kathathu eccentric butterfly valve yivelitha ejikelezayo, kwaye inyathelo layo lokujikeleza li-90 ° kuphela. Xa kuthelekiswa nevalve yamasango, iglowubhu yevali kunye nezinye izinto ezenziwayo zokujikeleza ngokujikelezayo, isithuba sayo sokupakisha sixhomekeke kwinqanaba lokunxiba eliphantsi kunye nobomi benkonzo ende. Ngaphaya koko, ngenxa yoyilo oluphezulu olwamkelwe nguTritec ekupakisheni itywina kunye nolunye ulwakhiwo lwangaphandle lokuthintela ukuvuza, inokusetyenziswa ngokuhambelana Xa uvavanyo lwangaphandle lokuvuza lwenziwa phantsi kwe-EPA 21, ukusebenza ngokutywina okuqinisekileyo kuqinisekisiwe ukuba kungaphantsi 100ppm
