Iyini ivalvu yesango le-DIN3352?
Ivalvu yesango le-DIN3352,isimiso sokuklama esibaluleke kakhulu uma kukhethwa ukusetshenziswa ezinhlelweni zokusabalalisa.
Ivalvu yesango le-DIN3352 iqukethe i-wedge ehlanganiswe ngokuphelele nerabha ye-EPDM eboshwe unomphela ku-wedge futhi ihlangana ne-ASTM D249. Umzimba wevalvu, i-bonnet, kanye nepuleti lokugcwala kugqokwe nge-epoxy eboshiwe ehlanganisiwe (FBE), ukubukeka okuhle kanye nokuvikelwa okuhle kakhulu. Ukulungiswa okukhethwa kukho kufaka phakathi i-Non-Rising Stem (NRS) noma i-Outside Screw & Yoke (OS&Y). Ivalvu yesango le-DIN3352 ingasebenza nge-Spur noma i-Bevel Gear, kanye ne-actuator kagesi.
Amavalvu esango le-DIN3352 athandwa kakhulu ekusetshenzisweni kwezimboni.
Izici eziyinhloko ze-valve yesango le-NORTECH DIN3352?
Umzimba yenziwe ngensimbi ethambile ngokubumba ngokunemba,Yaklanywa yisofthiwe ye-3D, enokuhlaziywa kwezinto ezilinganiselwe zesakhiwo. I-coefficient yokuphepha ingaphezu kuka-2.5. Isiteshi esiphansi esibushelelezi saklanywa, ukugwema ukuqongelela kokungcola nokuqinisekisa ukumelana okuncane kokugeleza.
IsiquYenziwe ngensimbi engagqwali ngokugingqa. Uhlobo oluhlanganisiwe, igwema ukusebenzisa izindandatho zethusi eziyingxenye ukunciphisa ububanzi besiqu. Isikulufu sohlobo lweladi esiguquliwe esibushelelezi sikhishwe. I-global mirror polish, ifanelana kahle nezindandatho ze-O, ukuqinisekisa ukuthi ukujikeleza okubushelelezi kanye ne-torque encane.
Amabhawodi ebanga lesi-8.8 axhumanisaibhonethikanye nomzimba, amabhawodi ayembozwe nge-wax encibilikayo evikela amabhawodi ekugqwaleni. I-gasket ephakathi kwebhonethi nomzimba yenziwe nge-EPDM. Isembozo se-valve sifakwe umsele wokugcina, qiniseka ukuthi i-gasket yerabha ngeke ikhishwe ngaphansi komfutho wamanzi aphezulu.
Ukukhiqiza okuhambisana nemvelo
Ubuso bangaphakathi nangaphandle bevalvu bumbozwe nge-epoxy powder ehlanzekile yi-fusion bonded epoxy (FBE), ubukhulu obujwayelekile bungaphezu kuka-250um. Ukunamathela kwengubo kuqinile, ngeke kubhujiswe ngaphansi kokuhlolwa kwamandla okushaya kwe-3J. Izingxenye zangaphakathi zingahlangabezana nezidingo zokuvikela imvelo, futhi zingasetshenziswa ngqo emanzini aphuzwayo, ukudla kanye nendawo yemithi. Inqubo yokumboza ngempuphu kagesi ingathembisa amandla aphezulu okunamathela kanye nokumelana nokugqwala okunamandla.
Izingxenye zerabha zenziwe nge-EPDM noma i-NBR esezingeni eliphezulu, okuhambisana nezidingo zamanzi okuphuza, okugwema inkinga yerabha evamile okungenzeka ukuthi izala amagciwane. Imikhiqizo ayivunyelwe nje kuphela yizindinganiso zekhwalithi zikazwelonke zaseShayina zemikhiqizo ehlobene namanzi okuphuza, kodwa futhi ivunyelwe yi-WRAS e-UK kanye ne-ACS eFrance. I-stem nut yenziwe futhi igoqwe kusuka endukwini yethusi ejwayelekile kazwelonke (okuqukethwe okuphansi kwe-lead), futhi akukho ukungcola emanzini.
Ukufakwa okulula nokusebenza
Sinikeza izinhlobo ezahlukene ze-interface njengokuxhumeka kwe-flange, isokhethi yepayipi le-PVC, isokhethi yepayipi lensimbi ye-uctile, ukunciphisa njll. Umklamo wokuxhumeka okhethekile ungenziwa ngokwezifiso ngokwezicelo.
Ivalvu ingavalwa ngokuphelele futhi ifinyelele lapho ivuza khona nge-torque encane. I-torque yangempela yokusebenza ingu-80% kuphela wobubanzi, futhi amavalvu esango angathwala i-MST ye-3 * DN NM. Imikhiqizo idlule ukuhlolwa kokuphila izikhathi ezingu-5000. Kumavalvu anobubanzi obukhulu, singanikeza amadivayisi okonga abasebenzi, ukuqinisekisa ukuthi wonke amavalvu angavulwa futhi avalwe ngumuntu oyedwa. Isondo lesandla liqinile, linobukhulu obunembile, lihambisana kahle nesiqu sevalvu, ukuma kwalo kuhambisana nobuchwepheshe bomuntu, ukuqinisekisa ukusebenza okulula.
Ukulungiswa okulula
Indandatho yokuvala ingashintshwa ngaphandle kokunqamula amanzi, kulula ukuyilungisa futhi kunciphisa isikhathi sokulungisa ngangokunokwenzeka. Ukungqubuzana okuncane kakhulu phakathi kwe-brass bushing kanye ne-"O" seal, kuzoqinisekisa ukuthi indandatho yokuvala ihlala isikhathi eside. I-torque ephezulu yokusebenza ilawulwa.
