Ulwakhiwo lwentsimbi ukuya kwintsimbi ehleliyo ivalve yebhola ehleliyo ibandakanya umzimba wevalve, ibhola yevalve, iringi yokutywina, isikhondo sevalve kunye nokupakishwa. Phakathi kwazo, i-valve yebhola kunye nendandatho yokutywina zizinto eziphambili, ngokuqhelekileyo zenziwe ngezinto ezikhuniweyo eziphezulu kunye ne-corrosion-resistant-resistant ezifana nensimbi engenasici okanye i-alloy high material. Umphezulu webhola kunye nomsesane wokutywina ngumhlaba ochanekileyo kwaye uqiniswe ukuqinisekisa ukulingana okuqinileyo phakathi kwebhola kunye neringi yokutywina ukufikelela kwisiphumo esihle sokutywinwa.

iinkcukacha zemveliso

Xa kuthelekiswa neevalvu zebhola ezitywiniweyo ezithambileyo, intsimbi ukuya kwintsimbi ehleli iivalvu zebhola azinayo nje iimpawu zokuxhathisa ulwelo oluphantsi, ukuvulwa nokuvala okukhawulezayo kunye nokulula, ukusebenza kakuhle kokutywina, ubomi benkonzo ende, ukuthembeka okuphezulu, kunye nokufakwa lula ngombane kunye nezixhobo zomoya, kodwa iyakwazi ukuziqhelanisa noluhlu olubanzi lobushushu kunye namasimi aphakathi kwamanzi. Ngoko ke, zisetyenziswa ngokubanzi ekuthuthweni kwemibhobho. Ibhola kunye nesihlalo sevalve yebhola etywiniweyo zombini zenziwe ngezinto zetsimbi, kwaye isibini sokutywina esakhiwe ngesinyithi kunye nezinto zetsimbi ngokuqhelekileyo zibizwa ngokuba sisitywina esiqinileyo. Iinkcukacha zoyilo lweevalvu zebhola ezitywiniweyo ziya kuhambelana ne-API 6D. Ikakhulu yenziwe ngumzimba wevalvu, isihlalo sevalve, ingqukuva, isiqu sevalvu, kunye nesixhobo sokuqhuba.

Kwizihlandlo ezingaphezulu kwe-100 ℃, sebenzisa isakhiwo sokupakisha sokutywina. Ibhola kunye nesitulo sevalvu zitywinwe ngamandla. Umphezulu woxinzelelo olumileyo lwesihlalo sevalve kunye nesiqu sevalve zitywinwe ngokupakishwa kwegraphite. Susa i-thrust pads phakathi kwesiqu sevalve kunye neflange yedlala, kunye naphakathi kwesphere kunye nepleyiti yokuxhasa. I-Gland flange kunye nepleyiti yokuxhasa i-nitrided. Esi sakhiwo asikhawulelwanga bubushushu bokusetyenziswa kwaye sinokusetyenziswa ngokubanzi ukuya kuma malunga nama-500 ℃;

Kwiimeko apho ubushushu bungaphantsi okanye bulingana no-100 ℃, sebenzisa i-O-ring yokutywina isakhiwo. Ubume bevalve yebhola esisigxina ngokuqhelekileyo bufana neso sevalve yebhola esisigxina (isixhobo sokutofa i-oyile siyafuneka kwisitulo sevalve kunye nesiqu sevalve). Umphezulu woxinzelelo olumileyo lwesihlalo sevalve kunye nesiqu sevalve zombini zitywinwe ngezitywina ze-O-ring, ngaphandle kokuba ibhola kunye nesitulo sevalvu zitywinwe ngamandla. Iiphedi ze-PTFE ezisulungekileyo zisetyenziswa phakathi kwesikhondo sevalve kunye neflange yedlala, kunye naphakathi kwepleyiti yenkxaso kunye nesphere.

Isakhiwo sokutywina sevalve yebhola etywiniweyo etywiniweyo enetywina yokupakisha ithatha isitulo sevalve eneelastiki, kunye neqela lemithombo icwangciswe ecaleni kwesangqa secandelo elinqamlezayo leshaneli yevalve ukuze isoloko igcina isitulo sevalve sicinezela ibhola kunye nokufikelela kwangaphambili. imeko eqinisiweyo. Xa uxinzelelo lwe-fluid kwisihlalo sevalve luphantsi kakhulu, luxhomekeke kwi-thrust of spring; Xa uxinzelelo lwe-fluid luphezulu, amandla angalinganiyo aveliswa luxinzelelo lwe-fluid kwisitulo sevalve siqinisekisa ukutywinwa. Indawo ecinezelweyo yesitulo sevalve inkulu kunendawo ecinezelekileyo ebuyela umva yesitulo sevalve. Amandla angalungelelananga aveliswa luxinzelelo lolwelo kwisihlalo sevalve enwebekayo sityhala isitulo sevalvu ukuya phambili ukuya kwingqukuva, ukucinezela nokugcina itywina. Ukuphakama koxinzelelo lolwelo, kokukhona kulungele ngakumbi ukutywinwa kwesi sakhiwo.

Iimpawu ezongezelelweyo

Kukho ngokubanzi iindidi ezimbini zoyilo lolwakhiwo lwevalvu yebhola etywiniweyo eqinileyo: uhlobo lwebhola edadayo kunye nohlobo olusisigxina lwebhola. Nokuba luhlobo luni lwesakhiwo, kwindawo esetyenziswa phantsi kweemeko ezirhabaxa zokunxiba, kuyafuneka ukuba kuthintelwe ukuqokelelwa kwezixhobo zegumbi lasentwasahlobo kwisitulo sevalve elastiki ekubeni ibangele ukuba ivalve ingasebenzi kakuhle, nto leyo ekhokelela ekunyukeni okungaqhelekanga kwetorque okanye "i-jamming". ivalve. Kule meko yokusebenza, umenzi uye wavelisa iivalvu zebhola ezizicocayo (uhlobo oludadayo) kunye nesakhiwo se-sedimentation esinxilisayo (uhlobo olusisigxina), olusombulula ngempumelelo le ngxaki.

Iivalvu zebhola ezitywiniweyo ezinentsimbi zineempawu zokuzicoca. Isitulo sevalvu edadayo enyukayo siyilwe njengesakhiwo setshaneli ezizicocayo esinomsebenzi wokuvuthela. Ngexesha lokuvula kunye nenkqubo yokuvala, i-valve inokuxhomekeka kuxinzelelo lwe-medium ngokwayo ukuba ivuthe kwaye itshayele izinto eziqokelelwe entwasahlobo kunye negumbi levalve, ukuze kuthintelwe amasuntswana aqinileyo ukuba angaqokeleli kwigumbi lasentwasahlobo kwaye abangele "tshixa". " isenzeko, esichaphazela ukusebenza kwesiqhelo kwevalvu; Isihlalo sevalve yokutywina sisakhiwo esinokutshintshwa; Yongeza iipadi ezimbini zokuzithambisa kwisiqu sevalvu ukunciphisa itorque yokusebenza kwevalvu.

Isitulo sevalve yentsimbi etywiniweyo sithatha uyilo lwesakhiwo "esikhokelayo", kunye netanki yokuthomalalisa yenzelwe phambi kokuqinisekisa ukuba ivalve inokufaka ngokufanelekileyo izinto phambi kwegumbi lasentwasahlobo ngexesha lokusetyenziswa, ngaphandle kokuchaphazela okuqhelekileyo. ukuhlehla kwesihlalo sevalve.

Usetyenziso

Iivalvu zebhola ezitywinwe ngesinyithi, ezineengenelo zazo ezikhethekileyo, zisetyenziswa kakhulu kwishishini lemichiza yamalahle, i-polysilicon, ukucocwa kwe-oyile, amaqonga angaphesheya konxweme, iinkqubo zokuhambisa amanzi emveli, kunye nezityalo zamandla. Kwiimeko ezifuna ukuvalwa okuqinileyo, ubushushu obuphezulu kunye nokuhluka koxinzelelo oluphezulu, ukuvulwa ngokukhawuleza kunye nokuvala, kunye neendaba eziqulethe iinqununu eziqinileyo, iivalve zebhola ezitywiniweyo zetsimbi ziluhlobo olukhethiweyo lwevalve. Nangona kunjalo, iivalve zebhola ezitywiniweyo zentsimbi zihlala zineengxaki ezinjengobomi benkonzo ephantsi, ukuvuza kwangaphakathi, kunye ne-jamming (okanye i-jamming) ngexesha lokusebenza. Ukujongana neemfuno zokunxiba ezikhulayo kunye neemeko ezinamandla zokhukuliseko, iivalvu zebhola ezikwaziyo ukunxiba kufuneka ziphuculwe ngokwemiqathango yonyango lomphezulu oqinileyo, uyilo lwesakhiwo, ukhetho lwamacandelo kunye nokusetyenzwa.
