Ivalvu yeBhola yokuVala Amanzi ephambili esuka phantsi komhlaba​ – NSW

Yintoni iValve yeBhola yokuShutha

A ivalvu yebhola yokuvalaluhlobo lwevalvu ejika ikota esebenzisa ibhola engenanto, eneembobo, nejikelezayo ukulawula ukuhamba kwamanzi. Xa isiphatho sevalvu sijikwa ngama-90 degrees, ibhola iyajikeleza ukuze ivumele amanzi ukuba adlule (indawo evulekileyo) okanye ayivale ngokupheleleyo (indawo evaliweyo). Uyilo lwayo olulula kodwa oluqinileyo lwenza ukuba ilungele ukusetyenziswa koxinzelelo oluphezulu, kuquka neenkqubo zemithombo engaphantsi komhlaba.

Iimpawu eziphambili zeevalvu zebhola

1. Uyilo lweZibuko ezipheleleyo: Ivumela ukuhamba kwamanzi ngaphandle kwemida xa ivuliwe.

2. Ulwakhiwo Oluhlala Luhleli: Yenziwe ngethusi, intsimbi engatyiwayo, okanye iPVC ukuze ikwazi ukumelana nokugqwala.

3. Ukusebenza ngokukhawuleza: Jika nge-90-degree ukuze ucime ngoko nangoko.

4. Isitywino Esiqinileyo Seebhamuza: Ithintela ukuvuza nokuba kuphantsi koxinzelelo oluphezulu.

Kutheni Usebenzisa iValve yeBhola yokuCima Amanzi ephambili kwiMithombo engaphantsi komhlaba

Iinkqubo zemithombo engaphantsi komhlaba zifuna iivalvu ezithembekileyo ukuze zikwazi ukujongana noxinzelelo olutshintshatshintshayo, inkunkuma, kunye neemeko ezinzima zokusingqongileyo. Nasi isizathu sokubaivalvu ephambili yokuvala amanzilolona khetho lubalaseleyo:

1. Ukuqina Okugqwesileyo Kwiimeko Ezinzima

Ukufakelwa komhlaba kubeka iivalvu kwindawo efumileyo, enesidi yomhlaba, kunye notshintsho lobushushu.Iivalvu zebhola, ingakumbi ezo zenziwe ngentsimbi engagqwaliyo okanye ngethusi, zimelana nokugqwala nokuwohloka ngcono kakhulu kunezinye iintlobo zeevalvu.

2. Iimfuno ezincinci zoLondolozo

Ngokungafaniyo neevalvu zesango okanye zeglobe, iivalvu zebhola zinezakhi ezimbalwa zangaphakathi, nto leyo enciphisa umngcipheko wokungasebenzi kakuhle koomatshini. Umphezulu wazo ogudileyo wangaphakathi nawo uyamelana nokwakheka kwesanti, ingxaki eqhelekileyo kwiinkqubo zemithombo.

3. Ukwazi ukucima i-case ngexesha likaxakeka

Kwimeko yokuvuza okanye ukugqabhuka kwemibhobho, ukujika ngokukhawuleza kwevalvu yebhola ngama-90 degrees kuqinisekisa ukuba amanzi ayayeka ukuhamba ngoko nangoko, okuthintela umonakalo omkhulu wamanzi.

4. Ukuhambelana noxinzelelo oluphezulu

Ii-Wells zihlala zivelisa uxinzelelo lwamanzi oluphezulu. Iivalvu zebhola zenzelwe ukumelana ne-1,000 PSI, nto leyo eyenza ukuba zilungele ukusetyenziswa kwe-main clotoff.

Ivalvu yeBhola vs. Ivalvu yeSango: Yeyiphi Engcono Kwimithombo Engaphantsi Komhlaba

Indlela Iivalvu Zesango Ezisebenza Ngayo

Ivalvu yesango isebenzisa isango elimile okwesikwere ukulawula ukuhamba kwamanzi. Ukuphakamisa isango kuvula ivalvu, ngelixa liyithoba livala ukuhamba kwamanzi. Nangona kunjalo, olu yilo luneengxaki ezibalulekileyo kwiinkqubo zemithombo yamanzi.

Umahluko ophambili: Ivalvu yeBhola vs. Ivalvu yeSango

Kutheni iiValve zeBhola ziphumelela:

- Iivalvu zesango zinobunzima "bokubopha isiqu" kwiindawo ezingaphantsi komhlaba ngenxa yokungcola okanye umhlwa.

- Ukuhamba kwe-throttling nge-valve yesango kuyayitshabalalisa isango, nto leyo ekhokelela ekungasebenzini kwangethuba.

Ivalvu yeBhola vs. Ivalvu yeButterfly: Yeyiphi Efanelekileyo kwiWells

Indlela Iivalvu Zebhabhathane Ezisebenza Ngayo

Ivalvu yebhabhathane isebenzisa idiski ejikelezayo ukulawula ukuhamba kwamanzi. Nangona incinci kwaye ifikeleleka ngexabiso eliphantsi, iyasokola kwiinkqubo zemithombo enoxinzelelo oluphezulu.

Umahluko ophambili: Ivalvu yeBhola vs. Ivalvu yeButterfly

Kutheni iiValve zeBhola ziphumelela:

- Idiski ephakathi yeevalvu zebhabhathane inciphisa ukusebenza kakuhle kokuhamba kwamanzi ngama-20–30%.

- Ulwelo lwerabha lwediski luwohloka ngokukhawuleza emanzini amdaka.

Ivalvu yeBhola vs. Ivalvu yeGlobe: Ebonelela ngokuCima okungcono

Indlela iiGlobe Valves ezisebenza ngayo

Iivalvu zeglobe zisebenzisa iplagi eshukumayo kunye nesihlalo sendandatho esingashukumiyo ukulawula ukuhamba kwamanzi. Zilungele kakhulu ukubhoboza kodwa azifanelekanga xa zicinywa.

Umahluko ophambili: Ivalvu yeBhola vs. Ivalvu yeGlobe

Kutheni iiValve zeBhola ziphumelela:

- Indlela yokuhamba kwe-globe valves efana no-S ibamba inkunkuma, nto leyo eyonyusa umngcipheko wokuxinana.

- Uyilo lwazo oluntsonkothileyo lufuna ukulungiswa rhoqo kwiindawo ezinzima.

Indlela yokukhetha iValve yeBhola yokuCima amanzi eyiNtloko echanekileyo

Izinto Ekufuneka Ziqwalaselwe

1. Izinto eziphathekayo: Intsimbi engenasici yokusetyenziswa komhlaba odlakadlaka, ubhedu olusetyenziswa kwiimeko eziphakathi.

2. Ubungakanani bePort: Iivalvu ezinezikhusi ezipheleleyo zinciphisa imida yokuhamba kwamanzi.

3. Uvavanyo loxinzelelo: Tshatisa i-PSI yevalvu kunye nesiphumo sepompo yakho yomthombo.

4. Uhlobo lwesiphatho: Izibambo ze-lever ukuze kube lula ukuzisebenzisa kwiindawo ezixineneyo.

Iingcebiso Zokufaka Ukusetyenziswa Phantsi Komhlaba

- Songa imisonto ngeteyipu yeTeflon ukuthintela ukuvuza.

- Faka ibhokisi yevalvu ukuze kube lula ukufikelela kuyo nokukhusela kwinkunkuma.

- Vavanya ivalvu rhoqo ngekota ukuqinisekisa ukusebenza kakuhle.

Isiphelo

A ivalvu ephambili yokuvala amanziyintshatsheli engenakuphikiswa kwiinkqubo zemithombo engaphantsi komhlaba. Ukuqina kwayo, uyilo lwayo olungenako ukuvuza, kunye nokugcinwa kwayo okuphantsi kufuna ukusebenza ngcono kuneevalvu zesango, ibhabhathane, kunye neglobe phantse kuzo zonke iimeko. Nokuba wakha umthombo omtsha okanye uphucula inkqubo ekhoyo, ukutyala imali kwivalvu yebhola esemgangathweni kuqinisekisa ulawulo lwamanzi oluthembekileyo kangangeminyaka emininzi.

Ngokuqonda umahluko phakathiivalvu yebhola xa ithelekiswa nevalvu yesango, ivalvu yebhola xa ithelekiswa nevalvu yebhabhathanekunyeivalvu yebhola xa ithelekiswa nevalvu yeglobhu, ungenza isigqibo esinolwazi esiza kukhusela unikezelo lwakho lwamanzi kwaye sinciphise iindleko zexesha elide.
