Unayo i-valve efanelekileyo kunye nombhobho, kodwa enye impazamo encinci ngexesha lofakelo inokubangela ukuvuza okungapheliyo. Oku kukunyanzela ukuba usike yonke into kwaye uqale phantsi, uchithe ixesha kunye nemali.

Ukufakela i-valve yebhola kumbhobho we-PVC, kufuneka uqale ukhethe uhlobo oluchanekileyo lokudibanisa: mhlawumbi i-valve enentambo usebenzisa i-PTFE tape okanye i-valve ye-socket usebenzisa i-PVC primer kunye ne-samente. Amalungiselelo afanelekileyo kunye nobuchule buyimfuneko kwitywina elingavuziyo.

Impumelelo yanoma yimuphi umsebenzi wemibhobho yehla kwiidibaniso. Ukufumana oku kulungile yinto endiyixoxa rhoqo namaqabane afana noBudi e-Indonesia, kuba abathengi bakhe bajongana nale mihla yonke. Ivalve evuzayo phantse ayinakuze ibe ngenxa yokuba ivalve ngokwayo imbi; kungenxa yokuba ijoyinti alenziwanga ngokuchanekileyo. Iindaba ezimnandi zezokuba ukwenza itywina eligqibeleleyo, elisisigxina kulula ukuba ulandela nje amanyathelo ambalwa alula. Olona khetho lubalulekileyo oza kulwenza kukugqiba ukuba usebenzise imisonto okanye iglu.

Indlela yokudibanisa ivalve yebhola kwiPVC?

Ubona iivalufa ezinemisonto kunye nesocket zikhona. Ukukhetha engalunganga kuthetha ukuba iindawo zakho aziyi kulunga, ukumisa iprojekthi yakho de ufumane ivalve elungileyo.

Uqhagamshela ivalve yebhola kwiPVC ngenye yeendlela ezimbini. Usebenzisa imidibaniso enemisonto (NPT okanye ye-BSP) kwiinkqubo ezinokufuna ukuqhawuka, okanye i-socket (i-solvent weld) udibaniso oludityanisiweyo olusisigxina, oluncamatheleyo.

Inyathelo lokuqala lihlala lihambelana nevalve yakho kwinkqubo yakho yombhobho. Ukuba imibhobho yakho yePVC sele ineziphelo ezinemisonto eyindoda, udinga ivalve enemisonto yabasetyhini. Kodwa kuninzi lomsebenzi omtsha wokunkcenkceshela okanye wokunkcenkceshela, uya kusebenzisa iivalvu zesokethi kunye nesamente yokunyibilikisa. Ndihlala ndikufumanisa kuluncedo xa iqela likaBudi libonisa abathengi itafile ukucacisa ukhetho. Indlela ilawulwa yivalve onayo. Awukwazi ukuncamathelisa ivalve enemisonto okanye uthunge ivalve yesokhethi. Eyona ndlela ixhaphakileyo nesisigxina yoqhagamshelo lwePVC ukuya kwiPVC yiisiseko, okanyei-solvent weld, indlela. Le nkqubo ayigcini nje ngokuncamathelisa amalungu; idibanisa ivalve kunye nombhobho ngokwekhemikhali ibe yiplastiki enye, engenamthungo, eyomeleleyo ngokumangalisayo kwaye ithembekile xa yenziwe ngokuchanekileyo.

Ukwahlulwa kweNdlela yoQhagamshelwano

Ingaba kukho indlela echanekileyo yokufakela ivalve yebhola?

Ucinga ukuba ivalve isebenza ngokufanayo kulo naliphi na icala. Kodwa ukuyifaka ngolungelelwaniso olungalunganga kunokuthintela ukuhamba, ukudala ingxolo, okanye kuyenze kungenzeki inkonzo kamva.

Ewe, kukho indlela echanekileyo. Ivalve kufuneka ifakwe isibambo esifikelelekayo, amandongomane omanyano (kwivalve yenyani yomanyano) ibekwe ukuze isuswe lula, kwaye isoloko ikwindawo evulekileyo ngexesha lokuncamathelisa.

Iinkcukacha ezininzi ezincinci zohlula ukufakwa kobuchwephesha kwi-amateur. Ekuqaleni,phatha uqhelaniso. Ngaphambi kokuba unamathele nantoni na, beka i-valve kwaye uqinisekise ukuba isibambo sinemvume eyaneleyo yokuguqula i-90 degrees epheleleyo. Ndibone iivalve ezifakwe kufutshane nodonga kangangokuba umqheba unokuvula nje embindini. Ivakala ilula, kodwa yimpazamo eqhelekileyo. Okwesibini, kwiivalvu zethu zoManyano lweNyaniso, sibandakanya amantongomane amabini omanyano. Ezi ziyilelwe ukuze ukwazi ukuzikhulula kwaye uphakamise umzimba wevalvu ngaphandle kombhobho wenkonzo. Kufuneka ufakele ivalve enegumbi elaneleyo lokukhulula la mandongomane. Elona nyathelo libalulekileyo, nangona kunjalo, yimeko yevalvu ngexesha lofakelo.

Elona nyathelo libalulekileyo: Gcina iValve ivuliwe

Xa uncamathisela (i-solvent welding) ivalve yesokhethi, ivalvekufunekaube kwindawo evuleke ngokupheleleyo. I-solvents kwi-primer kunye nesamente yenzelwe ukunyibilikisa i-PVC. Ukuba ivalve ivalekile, ezi zinyibilikisi zinokuvaleleka ngaphakathi kumzimba wevalvu kwaye zitshise ibhola ngekhemikhali ukuya kumngxuma wangaphakathi. Ivalve iya kuvalwa ngokusisigxina. Ndixelela uBudi ukuba le yeyona nto ibangela "ukusilela kwevalve entsha." Ayisosiphene sevalvu; yimpazamo yofakelo enokuthinteleka 100%.

Indlela yokuncamathelisa ivalve yebhola yePVC?

Usebenzisa i-glue kwaye unamathele iinxalenye kunye, kodwa idibeneyo ihluleka phantsi koxinzelelo. Oku kwenzeka ngenxa yokuba "i-gluing" ngokwenene yinkqubo yemichiza efuna amanyathelo athile.

Ukuncamathelisa ngokufanelekileyo i-valve yebhola ye-PVC, kufuneka usebenzise i-primer yamanyathelo amabini kunye nendlela yesamente. Oku kubandakanya ukucoca, ukusebenzisa iprimer emfusa kuyo yomibini imiphezulu, emva koko ufake isamente yePVC phambi kokuyidibanisa ngokujija.

Le nkqubo ibizwa ngokuba yi-solvent welding, kwaye idala ibhondi enamandla kunombhobho ngokwawo. Ukutsiba amanyathelo sisiqinisekiso sokuvuza kwexesha elizayo. Nantsi inkqubo esiqeqesha abasasazi beBudi ukuba bayilandele:

1. Yomisa Fit Kuqala.Qinisekisa ukuba umzantsi wombhobho uphumela ngaphandle ngaphakathi kwisokethi yevalvu.
2. Coca Amacandelo Omabini.Sebenzisa ilaphu elicocekileyo, elomileyo ukosula naluphi na ukungcola okanye ukufuma okuvela ngaphandle kombhobho nangaphakathi kwisokethi yevalve.
3. Faka i-Primer.Sebenzisa i-dauber ukufaka idyasi ye-liberal ye-PVC primer ngaphandle kwesiphelo sombhobho kunye nangaphakathi kwisokethi. I-primer ihlambulula umphezulu kwaye iqala ukuthambisa iplastiki. Eli lelona nyathelo litsityiweyo nelibaluleke kakhulu.
4. Faka iSamente.Ngelixa i-primer isemanzi, sebenzisa umaleko olinganayo wesamente yePVC ngaphezulu kweendawo eziphambili. Musa ukusebenzisa kakhulu, kodwa qinisekisa ukhuseleko olupheleleyo.
5. Qhagamshela kwaye Jija.Ngokukhawuleza tyhala umbhobho kwisokethi de uphume. Njengoko utyhala, yinike ithuba lekota. Le ntshukumo isasaza isamente ngokulinganayo kwaye isusa nawaphi na amaqamza omoya avalelekileyo.
6. Bamba kwaye Unyange.Bamba umdibaniso ngokuqinileyo kwindawo yawo malunga nemizuzwana engama-30 ukunqanda umbhobho ukuba ungaphuhli umva. Ungalichukumisi okanye uphazamise umdibaniso ubuncinane imizuzu eyi-15, kwaye uvumele ukuba uphilise ngokupheleleyo ngokwemiyalelo yomenzi wesamente ngaphambi kokuba ucinezele inkqubo.

Uyenza njani ivalve yebhola yePVC ibe lula?

Ivalve yakho entsha kraca yomelele kakhulu, kwaye unexhala lokukrazula isiphatho. Oku kuqina kunokukwenza ucinge ukuba ivalve inesiphene xa iluphawu lomgangatho.

Ivalve yePVC entsha, ekumgangatho ophezulu iqinile kuba izihlalo zayo zePTFE zenza itywina eligqibeleleyo, eliqinileyo ngokuchasene nebhola. Ukwenza kube lula ukujika, sebenzisa isikrufu kwi nut yesikwere kwisiseko somqheba ukuze ube ngcono ukuliqhekeza.

Ndifumana lo mbuzo ngalo lonke ixesha. Abathengi bafumana iPntek yethuiivalvekwaye bathi kunzima kakhulu ukujika. Oku kwenziwa ngabom. Amakhonkco amhlophe ngaphakathi, izihlalo ze-PTFE, zibunjwe ngokuchaneka ukwenza itywina eliqina kwiqamza. Olo kuqina lulo oluthintela ukuvuza. Iivalve ezingabizi kakhulu ezinamatywina akhululekileyo zijika ngokulula, kodwa zibuye zisilele ngokukhawuleza. Yicinge nje ngepere yezihlangu zethwathwa; kufuneka zaphulwe ngaphakathi. Eyona ndlela ingcono yokwenza oku kukusebenzisa isikrufu esincinci esinokulungiswa kwindawo engqindilili, yesikwere se-shaft yokubamba, ekunene kwisiseko. Oku kukunika amandla amaninzi ngaphandle kokubeka uxinzelelo kwi-T-handle ngokwayo. Emva kokuvula kunye nokuvala amaxesha ambalwa, iya kuba lula kakhulu.Ungaze usebenzise i-WD-40 okanye ezinye izithambiso ezisekelwe kwi-oyile.Ezi mveliso zinokuhlasela kwaye zinciphise iplastiki yePVC kunye ne-EPDM O-ring seals, ebangela ukuba i-valve ingaphumeleli ngexesha.

Ukuqukumbela

Ukufakwa ngokufanelekileyo, usebenzisa indlela yokudibanisa echanekileyo, i-orientation, kunye nenkqubo ye-gluing, yindlela yodwa yokuqinisekisa aIvalve yebhola yePVCinikeza ubomi benkonzo obude, obuthembekileyo, obungavuziyo.
