Zeziphi iivalvu ezinokusetyenziswa ukulawula uhlobo lwerhasi ekrelekrele iivalvu zokulawula imitha yamanzi

Ivalve yokulawula, ivalve yebhola, ivalve yebhabhathane, ivalve yesango ingasetyenziselwa ukulawula ivalve yegesi, yindlela yokulawula igesi, oku kulandelayo luhlu oluncinci lolwazi oluneenkcukacha, kubandakanya iimpawu zesakhiwo kunye nomgaqo wokusebenza kwezi valve zokulawula igesi. .
Umlawuli
Ivalve yokulawula isetyenziswa ngokubanzi kwiinkqubo zoshishino zento yokulawula. Ivalve elawulayo yenziwe liqumrhu elilawulayo kunye nevalve. Ngokwamalungu olawulo ahlukeneyo, inokwahlulwa ibe ivelufa yokulawula ipneumatic, ivalve yokulawula yombane kunye nevalve ezilawulayo. Ivalve yokulawula ngokwamkela inkqubo yemveliso ye-4-20MA isignali yokulawula ukufezekisa ukulawulwa ngokuzenzekelayo kunye nokulawula umoya.
Ivalve yebhola
Ivalve yebhola yenye yeevalvu ezisetyenziswa kakhulu kwihlabathi, kodwa nakwiminyaka elishumi edlulileyo uphuhliso olukhawulezayo lwevalve. Isetyenziselwa ikakhulu ukusika, ukulawula kunye nokusabalalisa kwimibhobho. Yivalve esebenzayo esetyenziswa ngokubanzi kulawulo lwegesi. I-valve yebhola idinga kuphela i-spool ukujikeleza i-90¡ã ukugqiba ukuvula nokuvala kunye nokunqumla ngokukhawuleza indima ye-medium.
Ivalve yebhabhathane
Ivalve yebhabhathane lixabiso eliphantsi, ulwakhiwo olulula lwevalve, ngoko ke ivalve yebhabhathane ifaneleke ngakumbi kwicaliber enkulu. Ivalve yebhabhathane ibonakaliswa ngumthamo omkhulu wokuqukuqela kunye nokumelana nolwelo oluncinci. Ngethuba nje i-butterfly plate ifikelela kwi-90¡ã, inokuvulwa kwaye ivalwe kanye, ukuze kufezekiswe utshintsho oluzenzekelayo lombhobho kunye nokunqunyulwa kunye nokulawulwa kwegesi.
Iivalvu zesango
Ivalve yesango inomzimba wevalve, isihlalo, isiqu, isango, isigqubuthelo sevalvu, iringi yokutywina kunye namanye amalungu. Iingenelo zevalve yesango sisakhiwo esixineneyo, ukuxhathisa ulwelo oluncinci, ubomi benkonzo ende, ngepleyiti yevalve phezulu nasezantsi intshukumo ukufezekisa ukuvulwa kwevalve kunye nolawulo lwegesi, xa ivalve yesango ivaliwe, indawo yokutywina ixhomekeke kuxinzelelo oluphakathi. umphezulu wokutywina wepleyiti yesango ukuya kwelinye icala lesihlalo sevalve ukuqinisekisa indawo yokutywina yendawo yokutywina.
Imitha yamanzi ehlakaniphile luhlobo olutsha lwemitha yamanzi esebenzisa iteknoloji ye-microelectronics yanamhlanje, iteknoloji yokuqonda yanamhlanje kunye neteknoloji yekhadi le-IC ehlakaniphile ukulinganisa ukusetyenziswa kwamanzi kunye nokudlulisa idatha yokusetyenziswa kwamanzi kunye nokulungisa ukuthengiselana. Okwangoku, ezona ntlobo ziphambili zeemitha zamanzi asekhaya iivalvu zolawulo lwe-elektroniki yivalve yebhola, ivalve yeceramic kunye nevalve ye-diaphragm.
Imitha yamanzi ehlakaniphile luhlobo olutsha lwemitha yamanzi esebenzisa iteknoloji ye-micro-electronic yanamhlanje, iteknoloji ye-sensing yanamhlanje kunye neteknoloji ye-IC ehlakaniphile yekhadi lokulinganisa ukusetyenziswa kwamanzi kunye nokudlulisa idatha yokusetyenziswa kwamanzi kunye nokulungisa ukuthengiselana. Okwangoku, ezona ntlobo ziphambili zeemitha zamanzi asekhaya iivalvu zolawulo lwe-elektroniki yivalve yebhola, ivalve yeceramic kunye nevalve ye-diaphragm.
Uhlobo lwevalve yokulawula yombane yemitha yamanzi ekrelekrele
(1) ivalve yebhola
Ivalve yebhola ngenxa yeemfuno zetorque yokuqhubela phambili, ngenxa yokwandiswa okanye ukunxitywa kokusetyenziswa, kulula ukuvuza, ukusilela kokutshintsha kunye nezinye iingxaki, imitha yamanzi ekrelekrele yasekhaya isebenzisa iivalvu ezinjalo ngakumbi, ekusebenziseni ezona ngxaki zininzi.
(2) ivalve yeceramic
I-valve ye-ceramic inobomi obude benkonzo, ukuthembeka okuphezulu kokutshintsha, ukulahleka koxinzelelo oluncinci, kwaye akulula ukulinganisa ukusetyenziswa. Kuba iyimveliso yelungelo elilodwa lomenzi wechiza, abavelisi bemitha yamanzi ekrelekrele basekhaya basebenzisa le valve bambalwa kwaye baphakathi kwayo.
(3) ivelufa ye-diaphragm
Iivalvu ze-diaphragm azifane zisetyenziswe ngabavelisi ngenxa yeendleko zabo eziphezulu. Ivalve yemitha yamanzi ekrelekrele ikwasisalathisi sokusebenza esibalulekileyo esisetyenziswayo.
Ngenxa yomgangatho wamanzi womnatha wombhobho, umonakalo kwi-valve yemitha yamanzi unzima, ochaphazela ngokuthe ngqo ukulinganisa kwemitha yamanzi. Ukukhethwa kwevalve yokulawula i-elektroniki kufuneka ibe nobomi obude, ukuthembeka okuphezulu kokutshintsha, ukulahlekelwa kwengcinezelo encinci, kwaye akulula ukulinganisa ukusetyenziswa. Okwangoku, ivalve yeceramic yeyona nto iphambili.
