Ukucaciswa kunye nokutolikwa kohlobo lwesivalo kunye nekhowudi yeleta
2023-09-08
I-valve sisixhobo esibalulekileyo kwinkqubo yokuhambisa umbane, esetyenziselwa ukulawula izinga lokuhamba, ulwalathiso lokuhamba, uxinzelelo, ubushushu kunye nezinye iiparitha zombane ukuqinisekisa ukusebenza okuqhelekileyo kwenkqubo yokuhambisa amanzi. Uhlobo lwevalve kunye nekhowudi yalo yeleta yimiqondiso ebalulekileyo yokusebenza kwevalve, isakhiwo, izinto kunye nokusetyenziswa kolwazi. Eli nqaku liza kutolika imodeli yevalve kunye nekhowudi yeleta yayo ukusuka kwindawo yokujonga umsebenzi. Okokuqala, ukubunjwa kwemodeli yevalve Imodeli yevalve yenziwe ngamacandelo asixhenxe, ngokulandelanayo: ikhowudi yeklasi, ikhowudi yokuhambisa, ikhowudi yokudibanisa, ikhowudi yesakhiwo, ikhowudi yezinto eziphathekayo, ikhowudi yoxinzelelo yokusebenza kunye nekhowudi yomzimba we-valve. Ezi nxalenye ezisixhenxe zimelelwe ngeeleta kunye namanani, apho ikhowudi yeklasi, ikhowudi yokudlulisa, ikhowudi yokudibanisa, ikhowudi yokwakha kunye nekhowudi yoxinzelelo yokusebenza iyadingeka, kunye nekhowudi yezinto eziphathekayo kunye nekhowudi yomzimba we-valve. Okwesibini, imimiselo yekhowudi ye-valve ikhowudi kunye nokutolikwa 1. Ikhowudi yeklasi: Ikhowudi yeklasi ibonisa ukusetyenziswa kunye nomsebenzi wevalve, kunye neleta "G" yeenjongo eziqhelekileyo, i-"P" ye-petroleum kunye ne-chemical valves, "H" yenqanawa. iivalvu, "Y" yeevalvu zesinyithi, njl. njl. 2. Ikhowudi yothumelo: ikhowudi yothumelo ibonisa indlela yokusebenza kwevalve, ngonobumba othi "M" wencwadana, "Q" ye-pneumatic, "D" yombane, "F" i-hydraulic, "B" ye-electro-hydraulic, njl. kuqhagamshelo lweflange, "N" yoqhagamshelwano lweflange olunemisonto, njl. njl. 4. Ikhowudi yefom yesakhiwo: ikhowudi yefom yesakhiwo ibonisa iimpawu zesakhiwo sevalve, echazwe ngoonobumba kunye namanani. Umzekelo, ikhowudi yesakhiwo sevalve yesango ngu-"Z", ikhowudi yefom ye-butterfly valve ithi "D", ikhowudi yefom ye-structural form yevalve yebhola ngu-"Q" njalo njalo. 5. Ikhowudi yezinto eziphathekayo: Ikhowudi yezinto eziphathekayo ibonisa iindawo eziphambili zezinto zevalve, ezimelwe ngoonobumba. Ngokomzekelo, ikhowudi yezinto eziphathekayo ze-carbon steel valve "C", ikhowudi yezinto eziphathekayo ze-valve yensimbi engenasici "S", ikhowudi yezinto eziphathekayo zevalve yensimbi "Z" njalo njalo. 6. Ikhowudi yoxinzelelo yokusebenza: Ikhowudi yoxinzelelo yokusebenza ibonisa ubuninzi bexinzelelo lokusebenza oluvunyelwe yi-valve phantsi kweemeko eziqhelekileyo zokusebenza, ezichazwe ngeeleta kunye namanani. Ngokomzekelo, i-valve enoxinzelelo olusebenzayo lwe-1.6MPa inekhowudi yoxinzelelo yokusebenza "16". 7. Ikhowudi yefom yevalvu yomzimba: ikhowudi yefom yomzimba yevalvu ibonisa ifom yesakhiwo somzimba wevalvu, emelwe ngoonobumba. Umzekelo, ikhowudi yefom yomzimba yevalvu ngu-"T", i-Angle through the valve body form code ngu-"A" njalo njalo. Okwesithathu, ukutolikwa kwemodeli yesivalo kunye nekhowudi yoonobumba Ukuthatha imodeli yevalve yesango esetyenziswa ngokuqhelekileyo "Z41T-16C" njengomzekelo, utoliko lolo hlobo lulandelayo: - "Z" ibonisa ukuba udidi lwevalve yisivalo senjongo ngokubanzi; - "4" ibonisa imowudi yothumelo ibhalwa ngesandla; - I-1 ibonisa ukuba uxhulumaniso ludityanisiwe. - "T" ibonisa ukuba isakhiwo yivalve yesango; - "16" ibonisa ukuba uxinzelelo lokusebenza yi-1.6MPa; - "C" ibonisa intsimbi ye-carbon. Ngokutolikwa oku ngasentla, unokuqonda ngokucacileyo udidi lwevalve yesango, imodi yokuhambisa, ifom yokudibanisa, ifom yesakhiwo, uxinzelelo lokusebenza kunye nolwazi lwezinto eziphathekayo. Iv. Ukuqukumbela Ukucaciswa kohlobo lwevalvu kunye nekhowudi yayo yeleta yinkcazo ebalulekileyo yobugcisa kwishishini levalvu, ebaluleke kakhulu ukuqinisekisa ukubekwa emgangathweni kunye nokutshintshana koyilo, ukuveliswa, ukukhetha kunye nokusetyenziswa kweemveliso zevalvu. Ukuqonda uhlobo lwe-valve kunye nenkcazo yekhowudi yeleta kunye nendlela yokutolika inceda ukukhetha ngokuchanekileyo kunye nokusebenzisa i-valve ukuqinisekisa ukusebenza okukhuselekileyo, okuthembekileyo kunye nokusebenza kakuhle kwenkqubo yokuhanjiswa kwamanzi.
