Sihlala sisebenzisa i-Pn, i-CLass, yindlela yoxinzelelo, umahluko kukuba bamele uxinzelelo phantsi kobushushu obuhambelana nesalathiso bohlukile, inkqubo ye-Pn yaseYurophu ibhekisa kuxinzelelo oluhambelanayo kwi-120 ℃, ngelixa umgangatho waseMelika ubhekisa kuxinzelelo oluhambelanayo Nge-425.5 ℃. Ke ngoko, kutshintshiselwano lobunjineli akunakho kuphela ukuguqula uxinzelelo, njenge-CLass300 # ngokutshintsha koxinzelelo kufanele ukuba kube yi-2.1 Mpa, kodwa ukuba uthathela ingqalelo ukusetyenziswa kweqondo lobushushu, uxinzelelo lwayo oluhambelanayo luya kuphakama, ngokokunyanzelwa kobushushu uvavanyo lulingana no-5.0 MPA.
Zimbini iintlobo zenkqubo yevalufa: enye yiJamani (kubandakanya neTshayina) njengommeli weqondo lobushushu eliqhelekileyo (i-China yi-100 degrees, iJamani ngama-120 degrees) uxinzelelo olusebenzayo olusebenzayo njengomgangatho wenkqubo “yoxinzelelo”. Enye yazo “yinkqubo yoxinzelelo lobushushu” emelwe yi-United States, esekwe kuxinzelelo lokusebenza oluvumelekileyo kubushushu obuthile. Kwinkqubo yoxinzelelo lobushushu baseMelika, onke amanqanaba asekwe kwiidigri ezingama-454 ngaphandle kwe-150LB esekwe kuma-260 degrees. I-150 lb (150psi = 1MPa) Udidi lwe-25 yentsimbi yentsimbi ene-1MPa kwi-260 degrees, kodwa uxinzelelo oluvumelekileyo kubushushu begumbi bukhulu kakhulu kunoko, malunga ne-2.0MPa.
Ke ngoko, kuthethwa ngokubanzi ukuba inqanaba loxinzelelo lwegama elihambelana ne-American Standard 150LB yi-2.0MPa, inqanaba loxinzelelo lwegama elihambelana ne-300LB yi-5.0MPa, njalo njalo. Ke ngoko, uxinzelelo lwegama kunye noxinzelelo lweqondo lobushushu alunakutshintshwa ngokomgaqo wokutshintsha koxinzelelo. I-Pn kukumelwa kwamanani kwikhowudi enxulumene noxinzelelo, kukubonelela ngenani elilula lesetyhula ukubhekisa kuyo, i-Pn ilingana noxinzelelo oluqhelekileyo lobushushu benombolo ye-Mpa, ihlala isetyenziswa kuxinzelelo lwegama lezivalo zasekhaya.
Yolawulo lwevalvevu yentsimbi yomzimba wekharbhodi yentsimbi, ibhekisa koxinzelelo oluphezulu olusebenzayo xa lusetyenziswe ngaphantsi kwe-200 ℃; Ngomzimba we-iron cast, ubuninzi boxinzelelo olusebenzayo oluvumelekileyo lwenkonzo engaphantsi kwe-120 ° C; Ukulawulwa kwezivalo ezinemizimba yentsimbi engenasici, ubuninzi boxinzelelo olusebenzayo oluvumelekileyo lwenkonzo engaphantsi kwe-250 ° C. Xa ubushushu obusebenzayo bonyuka, uxinzelelo lomzimba wevalve luyakuncipha. Ivaluva eziqhelekileyo zaseMelika zibonisa uxinzelelo lwegama kwigumbi leponti, nokubala kobushushu obophayo kunye noxinzelelo lwesinyithi ngokwe-ANSIB16.34. Esona sizathu siphambili sokuba ibanga leepawundi kunye noxinzelelo lwegama kungabikho enye-ukuya-kwenye imbalelwano kukuba inqanaba leponti kunye noxinzelelo lwegama luneedatum ezahlukeneyo zobushushu.
Sihlala sisebenzisa isoftware ukubala, kodwa kubalulekile ukuba sikwazi ukusebenzisa iitafile ukujonga amanqanaba obunzima. EJapan, ixabiso eliphambili le-K lisetyenziselwa ukubonisa inqanaba loxinzelelo. Uxinzelelo lwegesi, e-China, sihlala sisebenzisa ubunzima beyunithi "kg" (kunokuba "jin"), iyunithi ye-kg. Iyunithi yoxinzelelo ziikhilogram ngeesentimitha 2, kwaye ikhilogremu enye yoxinzelelo yikhilogrem enye yamandla esebenza kwisentimitha enye. Ngokunjalo, ngokuhambelana nelinye ilizwe, kuxinzelelo lwegesi, iyunithi yoxinzelelo esetyenziswa ngokuxhaphakileyo yi "psi", iyunithi ngu "1pound / intshi2 ″, ngu" Pound nge-intshi nganye yesikwere ", igama elipheleleyo lesiNgesi nguPonti nge-intshi nganye.
Kodwa kubizwa ngokuba yiyunithi yobunzima, okanye i-LB., eyi-LB. Nguwo amandla eponti. Zonke iiyunithi kwiiyunithi zeetriki zingasetyenzwa: 1psi = 1 iponti / Inch2 -0.068bar, 1bar≈14.5psi≈0.1MPa, iYurophu kunye ne-United States nakwamanye amazwe asetyenziselwa ukusebenzisa i-psi njengeyunithi. KwiClass600 nakwiClass1500 ehambelana nomgangatho waseYurophu kunye nomgangatho waseUnited States unamaxabiso amabini ahlukeneyo, i-11MPa (ehambelana nodidi lweepawundi ezingama-600) yimigaqo yenkqubo yaseYurophu, oku ku "ISO7005-1-1992 Steel Flanges" ngaphakathi izibonelelo; I-10MPa (ehambelana neklasi yeepawundi ezingama-600) ngummiselo wenkqubo yaseMelika, echazwe kwi-ASMEB16.5. Ke ngoko, akunakuthethwa ngokuqinisekileyo ukuba udidi oluhambelanayo lweepawundi ezingama-600 yi-11MPa okanye i-10MPa, kwaye amalungiselelo eenkqubo ezahlukeneyo ahlukile.
Inkqubo yeValve ubukhulu becala ineentlobo ezi-2: enye yiJamani (kubandakanya neTshayina) njengommeli kubushushu obuqhelekileyo (i-China yi-100 degrees, iJamani ngama-120 degrees) uxinzelelo olusebenzayo olusebenzayo njengomgangatho wenkqubo “yoxinzelelo”. Enye yenkqubo "yoxinzelelo lobushushu" emelwe yi-United States, esekwe kuxinzelelo lokusebenza oluvumelekileyo kubushushu obuthile. E-United States, inkqubo yoxinzelelo lobushushu isekwe kuma-454 degrees ngaphandle kwe-150LB ngokusekwe kuma-260 degrees.
Umzekelo, i-150LB. # 25 ikhabhoni yentsimbi yentsimbi inoxinzelelo oluvumelekileyo lwe-1MPa kwii-260 degrees, ngelixa uxinzelelo oluvumelekileyo kubushushu begumbi bukhulu kakhulu kunoko, malunga ne-2.0MPa. Ke ngoko, kuthethwa ngokubanzi ukuba inqanaba loxinzelelo lwegama elihambelana ne-American Standard 150LB yi-2.0MPa, inqanaba loxinzelelo lwegama elihambelana ne-300LB yi-5.0MPa, njalo njalo. Ke ngoko, uxinzelelo lwegama kunye noxinzelelo lweqondo lobushushu alunakutshintshwa ngokomgaqo wokutshintsha koxinzelelo.
