I-Valve Yesango Elihlala Njalo Eliqinile Elingakhuphukiyo le-DIN3352-F4 Ifektri yaseShayina
Iyini i-Non Rising Stem Gate Valve?
I-Valve Yesango Le-Stem Engakhuphuki,isimiso sokuklama esibaluleke kakhulu uma kukhethwa ukusetshenziswa ezinhlelweni zokusabalalisa.
I-Non Rising Stem Gate Valve iqukethe i-wedge ehlanganiswe ngokuphelele nerabha ye-EPDM eboshelwe unomphela ku-wedge futhi ihlangana ne-ASTM D249. Umzimba we-valve, i-bonnet, kanye ne-stuffing plate kugqokwe nge-fusion bonded epoxy (FBE), ebukeka kahle futhi ivikeleke kahle kakhulu.
Ama-valve e-Non Rising Stem Gate athandwa kakhulu ekusetshenzisweni kwezimboni.
- 1) Ukuvalwa okuphelele: ukuvalwa kwe-bubble okuqondisayo okubili.
- 2) Izindleko eziphansi: isihlalo serabha sivikelwe emphethweni, asikho isidingo sokuqhubeka nokulungisa isihlalo se-valve.
- 3) Isakhiwo Esilula kanye nokugcinwa okulula
Izici eziyinhloko ze-NORTECHNon Rising Stem Gate Valve
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
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 zesikhombikubona njengokuxhumeka kwe-flange, isokhethi lepayipi le-PVC, isokhethi lepayipi lensimbi elithambile, ukunciphisa njll. Umklamo wokuxhumeka okhethekile ungenziwa ngokwezifiso ngokwezicelo.yabasebenzisi.
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.
