Isakhiwo se-valve yebhola ehlezi yensimbi iye kwensimbi ikakhulukazi iqukethe umzimba we-valve, i-valve ibhola, indandatho yokuvala, isiqu se-valve kanye nokupakisha. Phakathi kwazo, ibhola le-valve nendandatho yokuvala yizici ezibalulekile, ngokuvamile ezenziwe ngezinto eziqinile eziqinile nezimelana nokugqwala njengensimbi engagqwali noma impahla yensimbi ye-alloy ephezulu. Indawo engaphezulu yebhola nendandatho yokuvala iwumhlaba oqondile futhi iqinile ukuze kuqinisekiswe ukungena okuqinile phakathi kwebhola nendandatho yokuvala ukuze kuzuzwe umphumela omuhle wokuvala.

Xhumana nathi

imininingwane yomkhiqizo

Uma kuqhathaniswa nama-valve ebhola avaliwe athambile, insimbi kuya kwensimbi ehlezi ama-valve ebhola ayinayo kuphela izici zokumelana noketshezi oluphansi, ukuvulwa nokuvala okusheshayo nokulula, ukusebenza kahle kokuvala, impilo ende yesevisi, ukwethembeka okuphezulu, nokufakwa kalula ngamadivaysi kagesi kanye ne-pneumatic, kodwa futhi ingakwazi ukuzivumelanisa nobubanzi obubanzi bezinga lokushisa nezinkambu eziwuketshezi. Ngakho-ke, asetshenziswa kakhulu ekuthuthweni kwamapayipi. Ibhola kanye nesihlalo se-valve yebhola evalwe kanzima zombili zenziwe ngezinto zensimbi, futhi i-pair yokuvala eyakhiwe ngezinto zensimbi nezensimbi ngokuvamile ibizwa ngokuthi uphawu oluqinile. Imininingwane yedizayini yamavalvu ebhola avalwe kanzima kufanele ihambisane ne-API 6D. Ikakhulukazi yakhiwe umzimba we-valve, isihlalo se-valve, i-sphere, isiqu se-valve, nedivayisi yokushayela.

Ezikhathini ezingaphezu kuka-100 ℃, sebenzisa isakhiwo sokupakisha sokuvala. Isihlalo sebhola nevalvu kuvalwe ngokuqinile. I-static pressure surface yesihlalo se-valve kanye nesiqu se-valve sivalwe ngokupakishwa kwe-graphite. Susa ama-thrust pads phakathi kwesiqu se-valve ne-flange ye-gland, kanye naphakathi kwe-sphere ne-support plate. I-Gland flange nepuleti lokusekela lifakwe nitrided. Lesi sakhiwo asinqunyelwe izinga lokushisa lokusetshenziswa futhi ngokuvamile singasetshenziswa kufika ku-500 ℃;

Ezimweni lapho izinga lokushisa lingaphansi noma lilingana no-100 ℃, sebenzisa isakhiwo sokuvala i-O-ring. Isakhiwo se-valve yebhola engashintshi ngokuvamile sifana naleso se-valve yebhola engaguquki evamile (idivayisi yokujova uwoyela iyadingeka esihlalweni se-valve kanye nesiqu se-valve). Indawo yokucindezela emile yesihlalo se-valve kanye nesiqu se-valve zombili zivaliwe ngezigxivizo ze-O-ring, ngaphandle kokuthi ibhola nesihlalo se-valve kuvalwe kanzima. Amaphedi e-PTFE ahlanzekile asetshenziswa phakathi kwesiqu se-valve ne-flange ye-gland, kanye naphakathi kwepuleti lokusekela kanye nembulunga.

Isakhiwo sokuvala se-valve yebhola eqinile evaliwe ene-packing seal ithatha isihlalo se-valve enwebekayo, futhi iqoqo leziphethu zihlelwe eduze komjikelezo we-valve channel cross-section ukuze njalo isihlalo se-valve sicindezele ibhola futhi sizuze ngaphambili. isimo esiqinisiwe. Lapho umfutho we-fluid esihlalweni se-valve uphansi kakhulu, uncike ekugxilweni kwentwasahlobo; Lapho umfutho we-fluid uphakeme, amandla angalingani akhiqizwa ukucindezela kwamanzi esihlalweni se-valve aqinisekisa ukuvala. Indawo ecindezelwe yesihlalo sevalvu inkulu kunendawo ecindezelwe ehlane yesihlalo sevalvu. Amandla angalingani akhiqizwa ukucindezela koketshezi esihlalweni sevalvu enwebekayo aphusha isihlalo sevalvu siye phambili siye endaweni, sicindezela futhi sigcine uphawu. Uma umfutho we-fluid uphakeme, kuba ngcono nakakhulu ukuvala lesi sakhiwo.

Izici Ezengeziwe

Ngokuvamile kunezinhlobo ezimbili zemiklamo yesakhiwo yamavalvu ebhola aqinile aqinile angagugi: uhlobo oluntantayo lwebhola kanye nohlobo olugxilile lwebhola. Kungakhathalekile ukuthi hlobo luni lwesakhiwo, endaweni esetshenziswa ngaphansi kwezimo ezinzima zokugqoka, kuyadingeka ukuvimbela ukuqoqwa kwezinto zegumbi lasentwasahlobo esihlalweni se-valve enwebekayo ekubangeleni ukuthi i-valve ingasebenzi kahle, okuholela ekwenyukeni okungavamile kwe-torque noma "i-jamming" ye-valve. i-valve. Kulesi simo sokusebenza, umkhiqizi uthuthukise ama-valve ebhola angazihlanzi (uhlobo oluntantayo) kanye nesakhiwo se-sedimentation esidambisayo ama-valve ebhola angavimbeli (uhlobo olulungisiwe), oluxazulula le nkinga ngempumelelo.

Ama-valve ebhola avaliwe ensimbi anesici sokuzihlanza. Isihlalo se-valve esintantayo siklanywe njengesakhiwo sesiteshi esizihlanzayo esinomsebenzi wokuvuthela. Phakathi nenqubo yokuvula nokuvala, i-valve ingancika ekucindezelweni kwe-medium ngokwayo ukuthi ivuthele futhi ishanele izinto eziqoqwe ekamelweni le-spring kanye ne-valve, ukuze kuvinjelwe izinhlayiya eziqinile ekuqongeleleni ekamelweni lasentwasahlobo futhi okungenzeka kubangele "ukuvala". " isenzakalo, esithinta ukusebenza okujwayelekile kwe-valve; Isihlalo se-valve yokuvala siyisakhiwo esingashintshwa; Engeza amaphedi amabili azithambisayo esiqwini sevalvu ukuze unciphise itorque yokusebenza kwamavalvu.

Isihlalo se-valve enwebekayo se-valve yebhola evalwe ngokuqinile yensimbi samukela ukwakheka kwesakhiwo "esiqondisayo", futhi ithangi lokuthambisa le-sedimentation lakhiwe ngaphambili ukuze kuqinisekiswe ukuthi i-valve ingakwazi ukufaka kahle izinto phambi kwegumbi lasentwasahlobo ngesikhathi sokusetshenziswa, ngaphandle kokuthikameze okujwayelekile. ukuhlehla kwesihlalo se-valve.

Izinhlelo zokusebenza

Ama-valve ebhola avaliwe ngensimbi, anezinzuzo zawo eziyingqayizivele, asetshenziswa kakhulu embonini yamakhemikhali amalahle, i-polysilicon, ukucwenga uwoyela, amapulatifomu angasogwini, amasistimu okudonsa amanzi ezitshalo zamandla endabuko, nasezitshalweni zikagesi. Ezimweni ezidinga ukuvalwa okuqinile, izinga lokushisa eliphezulu nokuhluka komfutho ophakeme, ukuvulwa nokuvala ngokushesha, kanye nemidiya equkethe izinhlayiya eziqinile, ama-valve ebhola avaliwe ensimbi awuhlobo olukhethwayo lwe-valve. Kodwa-ke, ama-valve ebhola ensimbi avalwe kanzima ngokuvamile anezinkinga ezifana nempilo yesevisi ephansi, ukuvuza kwangaphakathi, kanye nokugxumela (noma ukugxuma) ngesikhathi sokusebenza. Njengoba ubhekene nezidingo ezikhulayo zokugqoka kanye nezimo ezinamandla zokuguguleka, ama-valve amabhola angagugi kudingeka athuthukiswe ngokwemibandela yokwelashwa kwendawo eqinile, ukwakheka kwesakhiwo, ukukhethwa kwengxenye, nokucubungula.
