Ukuthuthukiswa kwe-valve elawulayo kusukela ekuqaleni kwekhulu lama-20 sekuyiminyaka engama-80 yomlando olawula i-valve ngokushesha ukuqeda ukushisa okujwayelekile ukwehluleka okuyisihlanu.

Ukuthuthukiswa kwe-valve elawulayo kusukela ekuqaleni kwekhulu lama-20 sekuyiminyaka engama-80 yomlando olawula i-valve ngokushesha ukuqeda ukushisa okujwayelekile ukwehluleka okuyisihlanu Ukuthuthukiswa kwe-valve yokulawula kusukela ekuqaleni kwekhulu lama-20 sekuyiminyaka engama-80 yomlando, kukhiqize izigaba eziyishumi imikhiqizo ye-valve elawulayo, ama-valve azimele kanye nama-positioners, njll., i-valve elawulayo kanye nenqubo yokuthuthukisa i-valve yokulawula imi kanje: 20 s: I-valve yokulawula ingcindezi yasekuqaleni ukuze uzinze yaphuma. 30 s: Ukuze "V" uthayiphe i-valve yesihlalo esiphindwe kabili kanye ne-valve yesitulo esisodwa semikhiqizo i-V yohlobo lwe-valve elawula ibhola yaphuma. 1940s: Ukuvela kwe-positioner, izinhlobo ezintsha zama-valve alawulayo ziphinde zikhiqizwe, i-diaphragm valve, i-Angle valve, i-butterfly valve, i-valve yebhola njalonjalo. 1950s: I-valve yebhola isetshenziswe kakhulu, i-valve yezindlela ezintathu esikhundleni se-valve enesihlalo esisodwa ohlelweni. 1960s: Ngemuva kokuthuthukiswa okuhleliwe kanye nokumiswa kwemikhiqizo engenhla e-China, uchungechunge oluphelele lwemikhiqizo lwakhiqizwa e-China. Manje sisasetshenziswa inombolo enkulu ye-valve yesihlalo esisodwa, i-valve enezihlalo ezimbili, i-Angle valve, i-valve yezindlela ezintathu, i-diaphragm valve, i-butterfly valve, i-valve yebhola imikhiqizo eyisikhombisa isesezingeni lemikhiqizo ngawo-1960. Ngalesi sikhathi, angaphandle waqala ukwethula uhlobo lwesishiyagalombili isakhiwo elawula valve - umkhono valve. 70's: Esinye isakhiwo esisha somkhiqizo - i-eccentric rotary valve yaphuma. Ngalesi sikhathi, ama-sleeve valves ayesetshenziswa kabanzi phesheya. Ngasekupheleni kwawo-1970, ukwakhiwa okuhlangene kwasekhaya kwe-sleeve valve, ukuze i-China ibe nomugqa wayo wemikhiqizo ye-sleeve valve. 1980s: Phakathi nenkathi yokuvula, i-China yethula ngempumelelo idivayisi ye-petrochemical kanye nobuchwepheshe be-valve elawulayo, ukuze i-valve yomkhono, i-eccentric rotary valve iye yanda futhi yasetshenziswa, ikakhulukazi i-sleeve valve, inamandla okushintsha i-valve yesihlalo esisodwa nesikabili, ukusetshenziswa kwayo kuya ngokuya kusabalele. Ekupheleni kweminyaka yama-80s, umlawuli uyinqubekelaphambili enkulu ku-Cv3000 yaseJapan kanye nesilawuli esincane esihle, bona esakhiweni, i-actuator eyodwa ye-spring pneumatic film actuator ibe i-multi-spring film actuator, isakhiwo se-valve sithuthukisiwe nje, asishintshiwe. Isici saso esivelele ukuthi isisindo nokuphakama kwe-valve elawulayo kwehla ngo-30%, futhi i-coefficient yokugeleza ikhuphuka ngo-30%. Ngaphezu kwalokho, inkampani yethu ithengisa imikhiqizo kanye nama-valve okulawula ukucindezela okuzimele, ama-valve alawula isihlalo esisodwa sikagesi nokunye, wamukelekile ukubonisana! Ukusebenza komkhiqizo okuhle kakhulu, isevisi iwukuphishekela kwethu okungapheli, sicela amakhasimende amasha namadala aqiniseke ukuthi athenge imikhiqizo ayithandayo. Lungisa i-valve ukuze uqede ngokushesha amaphutha amahlanu okushisa avamile 1. Amaphutha avamile: ukushisa akushisi sekukonke. Indlela yokuqeda: Vula i-inlet bese ubuyisela i-valve yamanzi. 2. Amaphutha avamile: ukushisa akushisi (i-valve ivuliwe). Ukushisa akushisi uhhafu. Kuzwakala umsindo wamanzi ohlelweni lokushisa. Indlela yokuqeda: Kungase kube negesi ohlelweni lokushisisa, futhi idinga ukuncibilika. Indlela yoku-1: Vala i-valve yokungena amanzi kuqala. Vula i-valve yokukhipha, ukuchichima kwamanzi, vala i-valve yokukhipha. Indlela yesibili: Vala i-valve yokungena ngo-3/4, bese uvala i-valve yamanzi okubuyisela, uvule i-valve ukuze ukhiphe, futhi uhhafu uvale i-valve yokukhulula lapho amanzi echichima. Khumbuza: Ngemva kokuhlinzwa, uma iphutha lingeke lisuswe, yazisa izisebenzi ezinakekela isondlo. 3. Amaphutha avamile: Ukushisa kwepayipi lokushisa akwanele, izinga lokushisa legumbi liphansi kakhulu. Indlela yokuqeda: Uma izinga lokushisa lokungena liphansi, nyusa izinga lokushisa lokungena. Uhlelo lokuhlola ngendawo. 4. Amaphutha avamile: I-inlet yamanzi namavalvu abuyayo ayavuza ngaphakathi (eduze nesistimu yokushisisa). Indlela yokuqeda: Vala i-inlet bese ubuyisela i-valve yamanzi. Yazisa ithimba lokufaka ukuze lilungiswe. 5. Amaphutha avamile: Ukuvuza kwamanzi ngaphandle kwendawo yokungena kanye namavalvu abuyayo (eduze komgwaqo omkhulu). Indlela yokuqeda: yazisa i-valve yesistimu eyingxenye evaliwe; Yazisa ithimba lokufaka ukuze lilungiswe.
