Amavalvu Esango Eliqinile Elihlala Ngensimbi E-GGG50 DIN 3352 F4 F5 kanye ne-BS 5163
Indlela Yokukhetha Ama-Valve Esango Ahlala Kahle Kakhulu Aqinile
Izinhlobo zeValve Yesango Elihlala Njalo
Amavalvu esango ahlala phansi avame ukusetshenziswa emanzini, emanzini angcolile, nakwezinye izinhlelo zokulawula uketshezi ngenxa yokuqina kwawo, ukulula kokusebenza, kanye nekhono lokunikeza ukuvala okuqinile. Lawa mavalvu asebenzisa izinto zesihlalo eziqinile, ngokuvamile ezi-elastomeric, ukuze anikeze umsebenzi wokuvala, okuwavumela ukuthi anikeze ukusebenza okuthembekile ngisho nasezindaweni ezidinga kakhulu. Ngezansi kunezinhlobo ezahlukene zamavalvu esango ahlala phansi aqinile, ahlukaniswe ngokusekelwe ezicini nasezintweni zokwakha ezahlukahlukene:
1. Amavalvu Esango Ahlala Ngokuqinile Ajwayelekile
Lezi yizinhlobo ezivame kakhulu zamavalvu esango ahlala kahle. Aqukethe umzimba wensimbi kanye nesihlalo serabha noma se-elastomeric, esinikeza umsebenzi wokuvala. Isihlalo sivame ukunamathela emzimbeni wevalvu futhi senzelwe ukumelana nengcindezi ngaphandle kokuguquka noma ukuvuza. Amavalvu esango ajwayelekile ahlala kahle asetshenziselwa izinhlelo zokusebenza ezijwayelekile lapho kudingeka khona ivalvu yokuvala elula nethembekile. Lawa mavalvu avame ukuba nomklamo wesiqu ongakhuphuki, osiza ekuvimbeleni ukugqwala futhi ovumela ukusebenza okubushelelezi.
Izici Eziyinhloko:
● Umzimba wensimbi onesihlalo se-elastomeric
● Umklamo wesiqu ongavuki
● Kufanelekela ukusetshenziswa kwengcindezi ejwayelekile
● Kusetshenziswa emanzini ahlanzekile, emanzini angcolile, nasezinhlelweni zezimboni
2. Amavalvu Esango Ahlala Ngokuqinile Angewona Aphakamayo (NRS)
Amavalvu esango ahlala eqinile esiqwini angavuki anesiqu esihlala singashukumi ngenkathi isango liphakama noma liwa ngenxa yokusebenza kwamavalvu. Lo mklamo uwusizo ekusetshenzisweni lapho imikhawulo yesikhala yenza iziqu eziphakamayo zingasebenzi. Amavalvu e-NRS avame ukusetshenziswa ekufakweni okugqitshwe noma okungaphansi komhlaba, njengoba engadingi ukuvuleka okungaphezu komhlabathi ukuze isiqu siphakame.
Izici Eziyinhloko:
● Isiqu asivuki ngesikhathi sokusebenza
● Ngokuvamile kusetshenziswa ezindaweni ezimboziwe noma ezivalwe isikhala
● Kulula ukunakekela nokusebenza ezindaweni ezixineneyo
● Kulungele izinhlelo zamanzi zikamasipala kanye nezitshalo zezimboni
3. Amavalvu Esango Ahlala Esisekelweni Esiqinile Esikhuphukayo
Ngokungafani nomklamo we-NRS, amavalvu esango ahlala esiqwini esikhuphukayo anesiqu esihamba phezulu naphansi nesango. Lolu hlobo lwevalvu luvame ukusetshenziswa ezisetshenziswayo ezingaphezu komhlabathi lapho indawo yesiqu inikeza inkomba ebonakalayo yokuthi ivalvu ivuliwe noma ivaliwe. Amavalvu esiqu esikhuphukayo avame ukusetshenziswa ezinhlelweni lapho isimo sevalvu sidinga ukubhekwa kalula.
Izici Eziyinhloko:
● Isiqu siyaphakama futhi siwa kanye nesango
● Inikeza inkomba ebonakalayo yendawo yevalvu
● Kuhle kakhulu ekufakweni lapho ukuqapha isimo se-valve kubalulekile khona
● Isetshenziswa kakhulu ezitshalweni zokuhlanza amanzi, izinhlelo zokuvikela umlilo, kanye nezinye ingqalasizinda ezibalulekile
4. Amavalvu Esango Ahlala Ngokuqinile
Amavalvu esango aqinile ahlala e-Flanged anezixhumanisi ezi-flanged ekugcineni komzimba wevalvu, okuvumela ukunamatheliswa kalula kumapayipi noma kwezinye izingxenye zesistimu. Lolu hlobo lwevalvu luvame ukusetshenziswa ezinhlelweni lapho ukuxhumeka okunamabholidi kuyadingeka khona ukuze kufakwe futhi kugcinwe. Amavalvu aqinile avame ukutholakala ezinhlelweni zamanzi zikamasipala, izinhlelo zokusebenza zezimboni, kanye nezinhlelo zokunisela.
Izici Eziyinhloko:
● Ukuxhumeka okunezimbobo ukuze kube lula ukukufaka
● Okuvamile kumapayipi amakhulu
● Isetshenziselwa izinhlelo zokusebenza ezinomfutho ophezulu noma ezihambayo kakhulu
● Kufanelekela amanzi, amanzi angcolile, kanye nokuthuthwa koketshezi lwezimboni
5. Amavalvu Esango Ahlala Eqinile E-Socket Weld
Amavalvu esango aqinile ahlala e-socket weld aklanyelwe amapayipi amancane lapho kudingeka khona uxhumano oluqinile noluphephile. Lawa mavalvu asebenzisa izinto zokufaka i-socket weld, ezihilela ukushisela ipayipi ngqo kusokhethi yamavalvu. Amavalvu e-socket weld avame ukusetshenziswa ezinhlelweni zokucindezela okuphezulu noma amapayipi amancane lapho ukuvimbela ukuvuza kanye nokuqina kwesakhiwo okuphezulu kubalulekile.
Izici Eziyinhloko:
● Ukuxhumeka kwe-socket weld ukuze kulingane kahle
● Kufanelekela izinhlelo ezincane ezinobukhulu obuncane nezinomfutho ophezulu
● Ivame ukusetshenziswa emigqeni yomusi, igesi, noma yamakhemikhali
● Ihlinzeka ngokuvala okuhle kakhulu kanye nengozi encane yokuvuza
6. Amavalvu Esango Ahlala Ngokuqinile Nama-Wedge Aguquguqukayo
Amavalvu esango ahlala e-wedge eguquguqukayo anesivikelo esiguquguqukayo anesivikelo esiguquguqukayo esenzelwe ukuhambisana nesihlalo, okuqinisekisa ukuvalwa okuqinile. Umklamo oguquguqukayo wesivikelo uyasiza ekumunceni ukwanda kokushisa, ukuguquguquka kwengcindezi, kanye nokudlidliza kwesistimu, okwenza lawa mavalvu afanelekele izinhlelo eziningi ezahlukene, okuhlanganisa izinhlelo zamanzi ashisayo kanye namapayipi ezimboni.
Izici Eziyinhloko:
● I-wedge eguquguqukayo yokuvala okuthuthukisiwe
● Kufanelekela izinhlelo ezinomfutho ophezulu kanye nezinokushisa okuphezulu
● Imunca ukucindezeleka kwesistimu njengokwanda kokushisa nokudlidliza
● Kusetshenziswa ezitshalweni zikagesi, ezimbonini zamakhemikhali, kanye nasezinhlelweni zikamasipala
7. Amavalvu Esango Ahlala Eqinile Ensimbi E-Ductile
Insimbi ethambile ivame ukusetshenziselwa ukwakha amavalvu esango aqinile ngenxa yamandla ayo aphezulu, ukuqina, kanye nokumelana nokugqwala. Lawa mavalvu avame ukumbozwa ngesendlalelo esivikelayo, njenge-epoxy noma i-polyurethane, ukuze kuthuthukiswe ubude bawo kanye nokumelana nezinto. Amavalvu ensimbi ethambile asetshenziswa kabanzi ezinhlelweni zokusabalalisa amanzi, ukuphathwa kwamanzi angcolile, kanye nezinhlelo zokulawula uketshezi lwezimboni.
Izici Eziyinhloko:
● Kwenziwe ngensimbi ethambile ukuze kuqiniswe amandla
● Izembozo ezingamelani nokugqwala ukuze ziqine ngokwengeziwe
● Okuvamile emanzini nasemanzini angcolile
● Ihlala isikhathi eside futhi ithembekile ngaphansi kwezimo zemvelo ezinzima
Amavalvu esango ahlala isikhathi eside afika ngezinhlobo ezahlukene, ngalinye lenzelwe izinhlelo zokusebenza ezithile kanye nezindawo ezithile. Kusukela ezinguqulweni ezijwayelekile nezine-flange kuya kulezo ezenziwe ngezinto ezihlala isikhathi eside njenge-ductile iron, lawa mavalvu ahlinzeka ngokusebenza okuthembekile kokubili ezinhlelweni eziphansi neziphezulu. Kungakhathaliseki ukuthi kungokwezokwelapha amanzi, izinqubo zezimboni, noma ukuphathwa kwamanzi angcolile, ukukhetha uhlobo olufanele lwevalvu yesango elihlala isikhathi eside kuqinisekisa ukusebenza okuphumelelayo nokuhlala isikhathi eside.
