Xisirhelelo xa ku tlhelela endzhaku lexitsongo
Nhlamuselo:
Vunyingi bya vaaki a va nghenisi xisirhelelo xa ku khuluka endzhaku eka phayiphi ya vona ya mati. I vanhu vatsongo ntsena lava tirhisaka check valve ya ntolovelo ku sivela back-low. Kutani yi ta va na ptall leyikulu ya vuswikoti. Naswona muxaka wa khale wa backflow preventer wa durha naswona aswi olovi ku humesa mati. Kutani a swi tika swinene ku tirhisiwa ngopfu enkarhini lowu hundzeke. Kambe sweswi, hi hluvukisa muxaka lowuntshwa ku swi tlhantlha hinkwaswo. Anti drip mini backlow preventer ya hina wil yi tirhisiwa ngopfu eka mutirhisi wa ntolovelo. Lexi i xitirhisiwa xo hlanganisa matimba ya mati hiku lawula ntshikelelo eka phayiphi kuva wu hetiseka ku khuluka ka ndlela yin’we. Swi wil sivela back-flow, papalata mitara ya mati leyi hundzuriweke na anti drip. Swi ta tiyisisa mati yo nwa lama hlayisekeke na ku sivela ku thyakisa.
Swihlawulekisi:
1. Straight-through sotted density design, ku tiya ka ku khuluka ka le hansi na mpfumawulo wa le hansi.
2. Xivumbeko xo koma, sayizi yo koma, ku olova install lation, hlayisa ndhawu yo veka.
3. Sivela ku hundzuriwa ka mitara ya mati na mintirho ya le henhla ya anti-creeper idling, .
drip tight ya pfuna eka vulawuri bya mati.
4. Switirhisiwa leswi hlawuriweke swi na vutomi byo leha bya ntirho.
Nsinya wa nawu wa Ntirho:
Yi endliwe hi ti check valve timbirhi hiku tirhisa threaded
ku hlanganisiwa.
Lexi i xitirhisiwa xo hlanganisa matimba ya mati hiku lawula ntshikelelo eka phayiphi kuva wu hetiseka eka ku khuluka ka ndlela yin’we. Loko mati ma fika, ti- disc timbirhi ti ta pfuleka. Loko yi yima, yi ta pfariwa hi xihlovo xa yona. Swita sivela back-flow naswona swita papalata mitara ya mati leyi hundzuriweke. Valve leyi yina vuyelo byin’wana: Tiyisisa ku lulama exikarhi ka mutirhisi na Water Supply Corporation. Loko ku khuluka ku ri kutsongo swinene ku ku chaja( ku fana na: ≤0.3Lh),valve leyi yi ta tlhantlha xiyimo lexi. Hikuya hi ku cinca ka ntshikelelo wa mati, mitara ya mati ya jika.
Ku vekiwa ka swilo:
1. Hlantswa phayiphi loko u nga si pfaleriwa.
2. Valve leyi yinga vekiwa eka horizontal na vertical.
3. Tiyisisa leswaku tlhelo ra ku khuluka ra le xikarhi na tlhelo ra museve swi fana loko u nghenisa.
