Ujonge kumbhobho, kwaye kukho umqheba ophumela ngaphandle. Kuya kufuneka ulawule ukuhamba kwamanzi, kodwa ukwenza ngaphandle kokwazi ngokuqinisekileyo kunokukhokelela ekuvuzeni, umonakalo, okanye kwindlela yokuziphatha engalindelekanga.

Ukusebenzisa umgangathoIvalve yebhola yePVC, vula isibambo ikota-turn (90 degrees). Xa isibambo sihambelana nombhobho, i-valve ivuliwe. Xa i-handle i-perpendicular kumbhobho, i-valve ivaliwe.

Oku kunokubonakala kusisiseko, kodwa lolona lwazi lusisiseko kuye nabani na osebenza ngemibhobho. Ndihlala ndixelela iqabane lam, uBudi, ukuba ukuqinisekisa ukuba iqela lakhe lokuthengisa linokucacisa ngokucacileyo ezi ziseko kwiikontraka ezintsha okanye abathengi be-DIY yindlela elula yokwakha ukuthembana. Xa umthengi eziva ezithembile ngemveliso, nokuba incinci, kusenokwenzeka ukuba bamthembe umsasazi obafundisayo. Linyathelo lokuqala kwintsebenziswano eyimpumelelo.

Isebenza njani ivalve yePVC?

Uyazi ukuguqula isiphatho kuyasebenza, kodwa awazi ukuba kutheni. Oku kwenza kube nzima ukucacisa ixabiso layo ngaphaya kokuba yi-on/off switch okanye ukulungisa ingxaki ukuba kukho into engahambi kakuhle.

Ivalve yebhola yePVC isebenza ngokujikelezisa ibhola engqukuva enomngxuma kuyo. Xa ujika isiphatho, umngxuma uhambelana nombhobho wokuhamba (uvule) okanye ujike ukuvala umbhobho (uvaliwe).

Ubukrelekrele beivalve yebholakukulula kunye nokusebenza kwayo. Xa ndibonisa isampula kwiqela likaBudi, ndihlala ndikhomba iindawo eziphambili. Ngaphakathi kwevalveumzimba, kukho iibholangomngxuma, owaziwa ngokuba lizibuko. Le bhola ihleli kakuhle phakathi kwamatywina amabini ahlala ehleli, esiyenza ngawo thina kwaPntekPTFEubomi obude. Ibhola idityaniswe nengaphandlephathangeposi ebizwa ngokuba yiisiqu. Xa uguqula isibambo se-90 degrees, isiqu sijikeleza ibhola. Le ntshukumo yekota yiyo eyenza iivalvu zebhola zikhawuleze kwaye kube lula ukusebenza. Luyilo olulula, olomeleleyo olubonelela ngokuvalwa okupheleleyo nokuthembekileyo okunamalungu ambalwa ashukumayo, yiyo loo nto ingumgangatho weenkqubo zolawulo lwamanzi kwihlabathi jikelele.

Uxela njani ukuba ivalve yePVC ivuliwe okanye ivaliwe?

Usondela kwivalve kwindlela entsonkothileyo yemibhobho. Awunakuqiniseka ukuba ivumela amanzi ukuba adlule okanye hayi, kwaye ukuqikelela okungalunganga kunokuthetha ukutshizwa okanye ukuvala umgca ongalunganga.

Jonga indawo yokubamba ngokumalunga nombhobho. Ukuba i-handle ihambelana (ihamba ngendlela efanayo nombhobho), i-valve ivuliwe. Ukuba i-perpendicular (ukwenza imilo engu-“T”), ivaliwe.

Lo mgaqo ubonwayo ngumgangatho weshishini ngesizathu: unengqondo kwaye awushiyi indawo yamathandabuzo. Umkhombandlela wesiphatho ulinganisa ngokwasemzimbeni imeko yezibuko ngaphakathi kwevalve. Ndihlala ndimxelela uBudi ukuba iqela lakhe kufuneka ligxininise lo mgaqo ulula- "Ukufana kuthetha ukuPasa, iPerpendicular ithetha iPlug." Olu ncedo luncinci lwenkumbulo lunokuthintela iimpazamo ezibiza imali eninzi kubalungisi bomhlaba, amagcisa echibini, kunye nabasebenzi bokugcina umzi-mveliso ngokufanayo. Luphawu lokhuseleko olwakhelwe kanye kuyilo. Ukuba ubona isibambo sevalve kwi-angle ye-45-degree, kuthetha ukuba ivalve ivuleke ngokuyinxenye, enokuthi ngamanye amaxesha isetyenziselwe ukuhamba kwe-throttling, kodwa uyilo oluphambili lweendawo ezivulekileyo okanye ezivaliwe ngokupheleleyo. Ukuvala i-positive, soloko uqinisekisa ukuba i-perpendicular ngokupheleleyo.

Indlela yokudibanisa ivalve kwipayipi yePVC?

Unevalve yakho kunye nombhobho, kodwa ukufumana isitywina esikhuselekileyo, esingqina ukuvuza kubalulekile. Ilungu elinye elibi linokuthomalalisa ingqibelelo yenkqubo yonke, nto leyo ekhokelela ekungaphumeleliyo nasekusebenzeni kwakhona okunexabiso elikhulu.

Kwivalve ye-weld ye-solvent, sebenzisa i-primer ye-PVC, emva koko isamente kwisiphelo sombhobho kunye nesokethi yevalve. Zityhale kunye kwaye zinike ithuba lekota. Kwiivalvu ezinemisonto, songela imisonto ngeteyiphu ye-PTFE phambi kokuba uqinise.

Ukufumana uxhulumaniso oluchanekileyo alunakuxoxisana kwinkqubo ethembekileyo. Le yindawo apho izinto ezisemgangathweni kunye nenkqubo echanekileyo yiyo yonke into. Ndicebisa iqela likaBudi ukuba lifundise abathengi babo ezi ndlela zimbini:

1. I-Socket Welding (ye-Socket Valves)

Le yeyona ndlela ixhaphakileyo. Idala umanyano olusisigxina, oludityanisiweyo.

1. Lungiselela:Yenza ukucoca, ukusika isikwere kumbhobho wakho kwaye ususe nayiphi na i-burrs.
2. Prime:Faka i-primer ye-PVC ngaphandle kombhobho kunye nangaphakathi kwisokethi yevalve. I-Primer ihlambulula umphezulu kwaye iqala ukuthambisa i-PVC.
3. Isamente:Faka ngokukhawuleza umaleko we-PVC yesamente phezu kweendawo eziphambili.
4. Qhagamshela:Ngokukhawuleza tyhala umbhobho kwisokethi yevalve kwaye uyinike ikota-ukujika ukusabalalisa isamente ngokulinganayo. Yibambe imizuzwana engama-30 ukunqanda umbhobho ukuba ungatyhala ngaphandle.

2. UQhagamshelwano Lwemisonto (yeeValuvu ezinemisonto)

Oku kuvumela ukuchithwa, kodwa ukutywinwa ngundoqo.

1. Iteyiphu:Songa iteyiphu ye-PTFE (iteyiphu yeTeflon) amaxesha angama-3-4 ujikeleze imisonto yamadoda ngendlela yewotshi.
2. Qinisa:Krwela ivalve ekuqiniseni ngesandla, emva koko sebenzisa isitshixo esinye ukuya kwezimbini. Musa ukuqinisa kakhulu, njengoko unokukrazula iPVC.

Indlela yokukhangela ukuba i-valve ye-PCV iyasebenza?

Ukrokrela ukuba ivalve iyasilela, ibangela imiba efana noxinzelelo oluphantsi okanye ukuvuza. Uva ngokujonga “ivalve yePCV” kodwa awuqinisekanga ukuba oko kusebenza njani kumbhobho wakho wamanzi.

Okokuqala, cacisa igama. Uthetha ivalve yePVC (iplastiki), hayi ivalve yePCV yenjini yemoto. Ukujonga ivalve yePVC, jika isiphatho. Kufuneka ihambe kakuhle 90 ° kwaye iyeke ngokupheleleyo ukuhamba xa ivaliwe.

Lo ngumahluko obaluleke kakhulu endiqinisekisa ukuba iqela likaBudi liyawuqonda. I-PCV imele i-Positive Crankcase Ventilation kwaye yinxalenye yolawulo lokuphuma emotweni. I-PVC imele iPolyvinyl Chloride, iplastiki yeevalvu zethu zenziwe ngayo. Umthengi ukuzixuba kuyinto eqhelekileyo.

Nalu uluhlu lokukhangela olulula ukubona ukuba aIvalve yePVCisebenza ngokuchanekileyo:

1. Jonga isiphatho:Ingaba ijika idigri ezipheleleyo ezingama-90? Ukuba yomelele kakhulu, amatywina anokuba madala. Ukuba ikhululekile okanye ijikeleza ngokukhululekileyo, isiqu esingaphakathi sinokwaphuka.
2. Hlola iindawo ezivuzayo:Jonga ithontsi ukusuka kumzimba wevalvu okanye apho isiqu singena khona kwisiphatho. E-Pntek, ukudibanisa kwethu okuzenzekelayo kunye novavanyo loxinzelelo lunciphisa le mingcipheko kwasekuqaleni.
3. Vavanya uVavanyo:Vala ivalve ngokupheleleyo (bamba i-perpendicular). Ukuba amanzi asahamba emgceni, ibhola yangaphakathi okanye izitywina zonakalisiwe, kwaye ivalve ayinakukwazi ukubonelela ngokuvala okulungileyo. Ifuna ukutshintshwa.

Ukuqukumbela

Ukusebenzisa aIvalve yePVCilula: phatha ukuhambelana kuthetha ukuvula, i-perpendicular ivaliwe. Ufakelo olufanelekileyo lwe-solvent-weld okanye i-threaded kunye nokuhlolwa okusebenzayo
