Ukukhethwa kunye nokusetwa kwevalvu yenxalenye yevalve yesixhobo sombane somzekelo wokulungiselela indlela
1. Xa ububanzi bombhobho bungekho mkhulu kune-50mm, ivalve yeglowubhu kufuneka isetyenziswe; xa i-diameter yombhobho inkulu kune-50mm, ivalve yesango kunye nevalve yebhabhathane kufuneka isetyenziswe; 2. Xa izinga lokuhamba lifuna ukulungiswa, uxinzelelo lwamanzi kufuneka luhlengahlengiswe ngokulawula i-valve kunye ne-globe valve.
Umgaqo-siseko wokukhethwa kweevalvu zokusetyenziswa kwimibhobho yokubonelela ngamanzi
1. Xa ububanzi bombhobho bungaphantsi kwama-50mm, ivalve yeglowubhu kufuneka isetyenziswe. Xa ubukhulu bombhobho bungaphezulu kwe-50mm, ivalve yesango kunye nevalve yebhabhathane kufuneka isetyenziswe
I-2, idinga ukulungelelanisa ukuhamba, uxinzelelo lwamanzi kufuneka lusebenzise i-valve yokulawula, i-valve yokumisa
3. Iivalvu zesango kufuneka zisetyenziswe apho ukuxhathisa ukuhamba kwamanzi kuncinci (njengombhobho wokufunxa impompo yamanzi)
4. Ivalve yesango kunye nevalve yebhabhathane iya kusetyenziswa kwicandelo lombhobho apho ukuhamba kwamanzi kumacala amabini, kwaye isivalo sokumisa singayi kusetyenziswa.
5. Ivalve yebhabhathane kunye nevalve yebhola kufuneka isetyenziswe kwindawo encinci yokufaka
6. Kwicandelo lombhobho elihlala livuliwe kwaye livaliwe, i-valve yokumisa kufuneka isetyenziswe
7, umbhobho wokuphuma wempompo wamanzi onomyinge omkhulu kufuneka usebenzise ivalve enemisebenzi emininzi
(2) Indawo yevalve kumbhobho wonikezelo lwamanzi
1. Umbhobho wonikezelo lwamanzi kwisithili esihlala abantu usuka kwicandelo lemibhobho ekhokelayo kumbhobho wonikezelo lwamanzi kamasipala
2. Iinqununu zenethiwekhi yombhobho wetyhula yangaphandle kwiindawo zokuhlala kufuneka zibekwe ngokweemfuno zokwahlula. Ukuba icandelo lombhobho we-annular lide kakhulu, iivalve ezicandiweyo kufuneka zimiselwe
I-3, ukusuka kumbhobho omkhulu wokubonelela ngamanzi kwiindawo zokuhlala ukususela ekuqaleni kombhobho wesebe okanye ekuqaleni kombhobho wendlu
4. Umbhobho wangaphakathi, imitha yamanzi kunye nesikhuphukeli sesebe ngasinye (ezantsi kwesikhuphukeli, indawo ephezulu nasezantsi yesikhuphukeli sombhobho weringi othe nkqo)
5, umbhobho wombhobho womnatha wesebe, umbhobho wokudibanisa umbhobho wesebe
6, umbhobho wokuhambisa amanzi ngaphakathi ezindlini, kwizindlu zangasese zikawonke-wonke, njl.
I-7, impompo yokukhupha impompo yamanzi, impompo yokunkcenkceshela yempompo yokufunxa
8. Itanki yamanzi yokungena kunye nemibhobho yokuphuma kunye nemibhobho yokuhambisa amanzi
I-9, izixhobo (ezifana ne-heater, inqaba yokupholisa, njl. njl.) umbhobho wokuzalisa amanzi
I-10, izixhobo zococeko (ezifana nenkulu, yokuchama, isitya sokuhlambela, ishawa, njl. njl.)
I-11, ezinye izesekeli, ezifana nevalve yokuphuma ngokuzenzekelayo, ivalve yokunciphisa uxinzelelo, i-hammer eliminator yamanzi, i-gauge yoxinzelelo, i-sprinkler bolt, i-valve yokunciphisa uxinzelelo kunye nesixhobo sokuthintela ukuhamba ngaphambi nasemva.
12. Ivalve yokuhambisa amanzi kufuneka ibekwe kwindawo esezantsi yothungelwano lwamanzi
(ezintathu) khangela ukhetho lwevalvu
Iivalve zokujonga kufuneka zikhethwe ngokwendawo yokufakela, uxinzelelo lwamanzi phambi kwevalve, iimfuno zokutywinwa kokusebenza emva kokuvalwa kunye nobukhulu besando samanzi esibangelwe xa kuvalwa, njl.
1. Xa uxinzelelo lwamanzi phambi kokuba ivalve incinci, uhlobo lwe-swing, uhlobo lwebhola kunye nevalve yokukhangela i-shuttle kufuneka ikhethwe.
2. Xa ukusebenza kwe-airtight emva kokuvalwa kufunwa ngokungqongqo, i-valve yokutshekisha ene-spring yokuvala kufuneka ikhethwe
3. Xa isando samanzi sifuneka ukuba sibe buthathaka kwaye sivalwe, kuyacetyiswa ukuba ukhethe ivalve yokujonga ukuvala ukuvala ngokukhawuleza okanye ivalve yokujonga ukuvala kancinci ngesixhobo sokuthambisa.
I-4, i-valve yokukhangela ikhefu okanye i-spool, kufuneka ikwazi ukuvala phantsi kwesenzo sobunzima okanye amandla entwasahlobo
(4) Izivalo zokukhangela ziya kufakelwa kwimibhobho yonikezelo lwamanzi
Kwipayipi; Kumbhobho wokungena we-heater yamanzi evaliweyo okanye izixhobo zamanzi; Kumbhobho okhupha impompo yamanzi; Kwicandelo lombhobho wokuphuma wetanki yamanzi, inqaba yamanzi kunye nedama elinyukayo lombhobho omnye.
Qaphela: iivalve zokutshekisha azifuneki kumacandelo emibhobho enezithinteli zokubuyela umva kombhobho.
(5) Indawo yesixhobo sokukhupha umbhobho wonikezelo lwamanzi
I-1, ukusetyenziswa okwethutyana kombhobho wonikezelo lwamanzi womnatha, isiphelo sothungelwano lombhobho kunye nendawo ephezulu kufuneka imiselwe ngevalve yokukhupha ngokuzenzekelayo.
2. Ivalve yokukhupha i-automatic okanye ivalve yesandla isetiwe kwindawo encopho yecandelo lombhobho ngoqokelelo olucacileyo lomoya ovuzayo kuthungelwano lonikezelo lwamanzi.
I-3, isixhobo sokuhambisa amanzi ngoxinzelelo lomoya, xa kusetyenziswa umatshini wokuzalisa umoya wokuzalisa umoya wetanki yamanzi, uthelekiso lomnatha wokuhambisa amanzi kufuneka luxhotyiswe ngevalve yokuphuma ngokuzenzekelayo.
