I-Rising Stem Soft Seal Cast Iron Gate Valve Ifektri yaseShayina
Iyini i-Soft Seal Gate Valve?
I-Soft Seal Gate Valve,isimiso sokuklama esibaluleke kakhulu uma kukhethwa ukusetshenziswa ezinhlelweni zokusabalalisa.
I-Soft Seal Gate Valve iqukethe i-wedge ehlanganiswe ngokuphelele nerabha ye-EPDM eboshwe unomphela ku-wedge futhi ihlangana ne-ASTM D249. Umzimba we-valve, i-bonnet, kanye ne-stuffing plate kugqokwe nge-fusion bonded epoxy (FBE), ukubukeka okuhle kanye nokuvikelwa okuhle kakhulu. Ukulungiswa okukhethwa kukho kufaka phakathi i-Non-Rising Stem (NRS) noma i-Outside Screw & Yoke (OS&Y). I-Soft Seal Gate Valve ingasebenza ne-Spur noma i-Bevel Gear, kanye ne-actuator kagesi.
Amavalvu Esango Lokuvala Okuthambile 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-NORTECH Soft Seal 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.
Uhlaka lweigejaYenziwe ngensimbi ethambile ngokubumba isihlabathi esimbozwe kusengaphambili, i-wedge imbozwe yi-EPDM ngokuphelele. Idizayini yesivalo esiphindwe kabili, umugqa ngamunye wesivalo ungasebenza ngokuzimela
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 zesikhombikubona njengokuxhumeka kwe-flange, isokhethi lepayipi le-PVC, isokhethi lepayipi lensimbi elithambile, ukunciphisa njll. Umklamo wokuxhumeka okhethekile ungenziwa ngokwezifiso ngokwezicelo.
yabasebenzisi. Amavalvu esango angasebenza nge-actuator kagesi, amasondo esandla, isivalo se-wrench noma ukhiye okhethekile. Kulula ukufaka amavalvu ezindaweni ezahlukene zemigqa yamapayipi. Ngaphandle kokufakwa okuqondile, amavalvu angafakwa ngokuvundlile. Kwezinye izindawo ezincane, ungakhetha indlela yokufaka elula ukusebenza kwamavalvu.
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.
