Ukuphuhliswa kwevalve yokulawula ukususela ekuqaleni kwenkulungwane yama-20 kuye kwaba yiminyaka engama-80 yembali yokulawula ivalve ngokukhawuleza ukuphelisa ukufudumeza okuqhelekileyo kweentsilelo ezintlanu iimveliso zevalve ezilawulayo, iivalve ezizimelayo kunye neendawo zokubeka, njl. njl., ivalve yokulawula kunye nenkqubo yophuhliso lwevalve yile ilandelayo: 20 s: Ivalve yokulawula uxinzelelo lwangaphambili lokuzinza yaphuma. 30 s: Ukuya ku "V" uhlobo olunotshi lwevalve yesitulo esiphindwe kabini kunye nevalve yesitulo esinye kwiimveliso V-uhlobo olulawula ivelufa yebhola yaphuma. 1940s: Ukuvela kwe-positioner, iintlobo ezintsha zeevalvu ezilawulayo ziveliswa ngakumbi, ivalve ye-diaphragm, i-Angle valve, ivalve yebhabhathane, ivalve yebhola njalo njalo. 1950s: Ivalve yebhola isetyenziswe ngokubanzi, ivalve yeendlela ezintathu endaweni yevalve yesitulo esinye kwisistim. 1960s: Emva kophuculo olulungelelanisiweyo kunye nokubekwa emgangathweni kwezi mveliso zingentla eTshayina, uluhlu olupheleleyo lweemveliso lwenziwa eTshayina. Ngoku sisasebenzisa inani elikhulu levalve yesitulo esinye, ivalve enezihlalo ezibini, ivalve yeAngle, ivalve yendlela ezintathu, ivalve yediaphragm, ivalve yebhabhathane, ivalve yebhola esixhenxe iimveliso zisekwinqanaba leemveliso kwiminyaka yoo-1960. Ngeli xesha, amazwe angaphandle aqala ukusungula uhlobo lwesibhozo lwesakhiwo esilawula ivalve - ivalve yomkhono. I-70's: Esinye isakhiwo esitsha semveliso - i-valve ye-rotary eccentric yaphuma. Ngeli xesha, iivalve zemikhono zazisetyenziswa ngokubanzi ngaphandle. Ngasekupheleni kweminyaka yoo-1970, uyilo oludityanisiweyo lwasekhaya lwevalve yomkhono, ukuze iTshayina ibe nomgca wayo weemveliso zevalve yomkhono. 1980s: Ngexesha lokuvula, iChina yazisa ngempumelelo isixhobo sepetrochemical kunye nokulawula itekhnoloji yevalve, ukuze ivalve yomkhono, ivalve ejikelezayo ye-eccentric yaziwe kwaye isetyenziswe, ngakumbi ivalve yomkhono, inamandla okutshintsha ivalve yesitulo esinye kunye nesiphindwe kabini, ukusetyenziswa kwayo kuxhaphake kakhulu. Ekupheleni kwe-80, umlawuli yinkqubela phambili enkulu kwi-Cv3000 yaseJapan kunye nolawulo oluncinci oluncinci, bona kwisakhiwo, i-actuator yefilimu ye-pneumatic eyodwa yasentwasahlobo ibe yi-actuator yefilimu ye-multi-spring, isakhiwo sevalve siphuculwe nje, asitshintshi. Isici sayo esibalaseleyo kukuba ubunzima kunye nokuphakama kwe-valve yokulawula yehla nge-30%, kwaye i-coefficient yokuhamba inyuka ngama-30%. Ukongeza, inkampani yethu ithengisa iimveliso kunye nokuzimela koxinzelelo lweevalvu ezilawulayo, iivalvu ezilawula isihlalo esinye sombane njalo njalo, wamkelekile ukudibana! Ukusebenza kwemveliso okugqwesileyo, inkonzo yinjongo yethu engapheliyo, nceda abathengi abatsha nabadala baqiniseke ukuba bathenge iimveliso abazithandayo. Lungisa i-valve ukuphelisa ngokukhawuleza iimpazamo ezintlanu eziqhelekileyo zokufudumeza 1. Iimpazamo eziqhelekileyo: ukufudumala akushushu ngokubanzi. Indlela yokuphelisa: Vula i-valve yamanzi yokungena kunye nokubuyisela. 2. Iimpazamo eziqhelekileyo: ukufudumeza akushushu (i-valve ivuliwe). Ukufudumeza akushushu ngesiqingatha. Kukho isandi samanzi kwisixokelelwano sokufudumeza. Indlela yokuphelisa: Kusenokubakho irhasi kwindlela yokufudumeza, kwaye kufuneka icocwe. Indlela yoku-1: Vala ivalve yokungena amanzi kuqala. Vula ivalve yokukhupha, ukuphuphuma kwamanzi, vala ivalve yokukhupha. Indlela yesibini: Vala ivalve yokungena ngo-3/4, emva koko uvale ivalve yokubuya, uvule ivalve ukuze ukhuphe, kwaye isiqingatha sivale ivalve yokukhulula xa kukho ukuphuphuma kwamanzi. Khumbuza: Emva kotyando, ukuba isiphene ayikasuswa, yazisa abasebenzi besondlo. 3. Iimpazamo eziqhelekileyo: Ukushisa kombhobho wokufudumeza akwanele, ukushisa kwegumbi kuphantsi kakhulu. Indlela yokuphelisa: Ukuba iqondo lokushisa lokungena liphantsi, yongeza iqondo lokushisa lokungena. Inkqubo yokuhlola ngepropati. 4. Iimpazamo eziqhelekileyo: I-inlet yamanzi kunye neevalvu zokubuyisela zivuza ngaphakathi (kufuphi nenkqubo yokufudumala). Indlela yokuphelisa: Vala i-valve yokungena kunye nokubuyisela amanzi. Yazisa iqela lofakelo ukuze lilungiswe. 5. Iimpazamo eziqhelekileyo: Ukuvuza kwamanzi ngaphandle kwendawo yokungena kunye nezivalo zokubuyisela (kufuphi nendlela enkulu). Indlela yokuphelisa: yazisa ipropathi enesiqingatha sevalve yenkqubo evaliweyo; Yazisa iqela lofakelo ukuze lilungiswe.
