Inkcazo emfutshane yokusebenza kwesixhobo sombane sevalve ejike kaninzi (Uhlobo Z) Isixhobo sokulawula ukuhamba, uxinzelelo, kunye necala lokuhamba kolwelo (ulwelo, igesi, ulwelo lwerhasi, okanye umxube oqinileyo wolwelo). Kubhekiselwa kuyo njenge "valve. Ngokuqhelekileyo ibandakanya umzimba wevalve, isivalo sevalvu, isihlalo, indawo zokuvula kunye nokuvala, indlela yokuqhuba, izitywina kunye neziqhoboshi. Umsebenzi wokulawula wevalve kukuxhomekeka kwindlela yokuqhuba okanye ulwelo ukuqhuba ukuphakamisa, ukutyibilika. , ukuguqula okanye ukuguqula ubungakanani bendawo yomjelo wokuhamba ukuze kuphunyezwe *** isetyenziswe kwimveliso yemveliso kunye nezolimo kunye nezixhobo zokuphila zemihla ngemihla ezenziwe e-China Phambi kwe-2000 BC, iibhobho ze-bamboo kunye neevalvu zeplagi zasetyenziswa kwimibhobho yamanzi. E-China kamva, iivalvu zamanzi zazisetyenziswa kwimijelo yokunkcenkceshela, iivalvu zokukhangela iipleyiti zazisetyenziselwa ukunyibilikisa imibhobho yokunyibilikisa, kunye nemibhobho yoqalo kunye neevalvu zokujonga iipleyiti zasetyenziswa kwimigodi yetyuwa ukuze kutsalwe amanzi etyuwa. Iivalve zeplagi zobhedu kunye ne-lead zavela eYurophu Ngo-1681, i-valve ye-lever ye-hammer yavela ngo-1769. Emva koko, ngenxa yophuhliso lwamandla ombane, i-petroleum, imboni yeekhemikhali kunye neshishini lokwakha iinqanawa, ukusetyenziswa kwezinto ezintsha ezahlukeneyo, zonke iintlobo zeevalvu ziye zazalwa kwaye zaphuhliswa ngokukhawuleza, ukuveliswa kwevalve kuye kwaba yinxalenye ebalulekileyo yoshishino lomatshini. Iivalvu ziyafumaneka ngokubanzi. Ngokomsebenzi wosetyenziso, inokwahlulwa ibe: ① ivalve yebhloko. Isetyenziselwa ukunqumla okanye ukufakwa phakathi kokuhamba okuphakathi, kubandakanywa ivalve yesango, ivalve yeglowubhu, ivalve ye-diaphragm, ivalve yeplagi, ivalve yebhola, ivalve yebhabhathane, njl. njl. ② Ivalve yokulawula. Ukulawula ukuhamba kunye noxinzelelo lwe-fluid, iivalve ezenziwe e-China ziquka iivalve ezilawulayo, i-throttle valves, i-valve yokunciphisa uxinzelelo kunye nokunye. ③ Jonga ivalve. Isetyenziselwa ukumisa ulwelo ukuba lungabuyeli ngasemva. (4) ivalve ye-shunt. Isetyenziselwa ukukhupha, ukwahlula kunye nokuxuba ulwelo, kubandakanywa iivalvu zesilayidi, iivalve zendlela ezininzi, imigibe, njl njl. ⑤ Ivalve yokhuseleko. Isetyenziselwa ukhuseleko lokhuseleko olugqithisileyo, ukuthintela ibhoyila, isitya soxinzelelo okanye umonakalo wombhobho, njl.njl Ukongeza, ngokoxinzelelo olusebenzayo lunokwahlulwa lube yivacuum valve, ivalve yoxinzelelo oluphantsi, ivalve yoxinzelelo oluphakathi, ivalve yoxinzelelo oluphezulu, ivalve ephezulu yoxinzelelo; Ngokutsho kobushushu bokusebenza kunokwahlulwa kwivalve yobushushu obuphezulu, ivalve yobushushu obuphakathi, ivalve yobushushu obuqhelekileyo, ivalve yobushushu obuphantsi; Ngokwendlela yokuqhuba, inokwahlulwa ibe yivalve yezandla, ivalve yombane, ivalve yepneumatic, ivalve yehydraulic, njl.njl. Ngokwesixhobo somzimba wevalve inokwahlulwa ibe yivalve yentsimbi, ivalve yentsimbi, ivalve yentsimbi ekhandiweyo, njl. Ngokweempawu zesebe lokusetyenziswa, linokwahlulwa libe yivalve yaseMarine, ivalve yokufudumeza amanzi, ivalve yesitishi samandla njalo njalo. Iiparamitha ezisisiseko zevalve luxinzelelo olusebenzayo, ubushushu bokusebenza kunye nomgangatho. Iivalvu ezahlukeneyo zemibhobho yemizi-mveliso, uxinzelelo oluqhelekileyo olusetyenziswa kwi-pN (uxinzelelo oluphezulu lokusebenza oluvumelekileyo ukuba luthwale phantsi kobushushu obuchaziweyo) kunye nedayamitha ye-DN (idayamitha yegama lomzimba wevalve kunye nokuphela koqhagamshelo lombhobho) njengeeparamitha ezisisiseko. I-valve ivalwe kakhulu, amandla, ukulawulwa, ukujikeleza, ukuvula kunye nokuvala ukusebenza, phakathi kwazo ezimbini zokuqala ziyisiseko esibaluleke kakhulu kuzo zonke iivalve. Ukuze kuqinisekiswe ukutywinwa kunye namandla e-valve, ngaphezu kwemigangatho echaphazelekayo kufuneka ihambelane noyilo olufanelekileyo lwesakhiwo, ukuqinisekisa umgangatho wenkqubo, kodwa kwakhona kufuneka kube nezinto ezikhethiweyo ezichanekileyo. Inkcazo yokusebenza kwesixhobo sombane se-valve ye-multi-turn (uhlobo lwe-Z) Isixhobo sombane se-valve ye-multi-turn inomsebenzi opheleleyo, ukusebenza okuthembekileyo, inkqubo yolawulo oluphezulu, ubungakanani obuncinci, ubunzima obulula, kulula ukuyisebenzisa kunye nokugcinwa, njl. kumandla ombane, isinyithi, i-petroleum, ishishini lemichiza, ukwenza iphepha, ukucocwa kogutyulo kunye namanye amasebe. Isixhobo sombane se-Multi-turn valve, eyaziwa ngokuba yi-Z - uhlobo. Ifanelekile kwisixhobo sombane se-valve ye-multi-turn ene-straight motion, eyaziwa ngokuba yi-Z. Ifanelekile i-valve ye-valve echanekileyo, njenge-valve yesango, i-valve yeglobhu, i-diaphragm valve, isango lamanzi, njl njl. Isetyenziselwa ukuvula ivalve, ukuvala okanye ukulungiswa, yisivalo sokufikelela kulawulo olukude, ulawulo oluphakathi kunye nolawulo oluzenzekelayo lwesixhobo sokuqhuba esibalulekileyo. Multi-turn electric device, drive device, electric head, ivalve yofakelo lombane imodeli Multi-rotary valve isixhobo sombane indawo yokusebenza: 3.2.1 Ubushushu be-Ambient: -20+60℃ (iodolo ezikhethekileyo -60+80℃) 3.2.2 Ubushushu obunxulumeneyo : 90% (ku-25 ℃) 3.2.3 Uhlobo oluqhelekileyo kunye nohlobo lwangaphandle lusetyenziswa kwiindawo ezingenayo imidiya enokutsha / eqhumayo kunye neyokuhlwa; Iimveliso ezikhusela uqhushumbo yi-D ⅰ kunye ne-D ⅱ BT4, i-D ⅰ ilungele ubuso obungasebenziyo bomgodi wamalahle; D ⅱ BT4 esetyenziswa kwiifektri, ilungele imo engqongileyo ye-ⅱ A, ⅱ B T1-T4 iqela lemixube yegesi yesondo. (Jonga i-GB3836.1 ngeenkcukacha) 3.2.4 Ibakala lokhuseleko: IP55 yohlobo lwangaphandle nolunobungqina bokudubula (IP67 inokwenziwa ngokwezifiso). 3.3.5 Ishedyuli yokusebenza: imizuzu eyi-10 (imizuzu engama-30 inokwenziwa ngokwesiqhelo). Isixhobo sombane sevalve yokujika kaninzi (UHlobo lwe-Z) isixhobo sokuqhuba, intloko yombane, isixhobo sombane sevalve, i-valve actuator, umqhubi wevalvu, ukusebenza kwevalvu yombane we-actuator Ngokwendawo yokusetyenziswa: Z luhlobo oluqhelekileyo; ZW luhlobo lwangaphandle; I-ZB ayinamlilo; I-ZZ luhlobo olubalulekileyo; I-ZT luhlobo olulawulayo. Ngokwamandla emveliso: uhlobo lwetorque kunye nohlobo lokutyhala. Ukusebenza kwemveliso kuhambelana ne-JB/T8528-1997 "Iimfuno zobugcisa ze-valve yohlobo oluqhelekileyo lwesixhobo sombane". Ukusebenza kohlobo lobungqina bokudubula buhambelana nemimiselo ye-GB3836.1-83 "Iimfuno ngokubanzi zezixhobo zombane ezingenakuqhushumba kwindawo yesondo", GB3836.2-83 "Isixhobo sombane esingenaziqhushumbisi sesondo seSixhobo soMbane esingenamlilo D" kunye ne-JB/T8529-1997 "Iimeko zobuchwephesha kwisixhobo sombane se-valve ye-flameproof".
