Une-valve efanele kanye nepayipi, kodwa iphutha elilodwa elincane ngesikhathi sokufakwa lingabangela ukuvuza unomphela. Lokhu kuphoqa ukuthi unqamule yonke into futhi uqale phansi, umoshe isikhathi nemali.

Ukufaka i-valve yebhola epayipini le-PVC, kufanele uqale ukhethe uhlobo lokuxhuma olulungile: kungaba ivalvu ecushiwe esebenzisa itheyiphu ye-PTFE noma i-valve yesokhethi esebenzisa i-PVC primer nosimende. Ukulungiselela kahle kanye nenqubo kubalulekile ukuze isivalo singavuzi.

Impumelelo yanoma yimuphi umsebenzi wamapayipi wehlela ekuxhumekeni. Ukulungisa lokhu kuyinto engivame ukuxoxa ngayo nozakwethu abafana no-Budi e-Indonesia, ngoba amakhasimende akhe abhekana nalokhu nsuku zonke. I-valve evuzayo cishe ayilokothi ngenxa yokuthi i-valve ngokwayo yimbi; yingoba ilunga alenziwanga ngendlela efanele. Izindaba ezinhle ukuthi ukudala uphawu oluphelele, oluhlala njalo kulula uma ulandela izinyathelo ezimbalwa ezilula. Isinqumo esibaluleke kakhulu oyosenza sinquma ukuthi uzosebenzisa izintambo noma iglue.

Indlela yokuxhuma i-valve yebhola ku-PVC?

Ubona ama-threaded nama-socket valves atholakalayo. Ukukhetha engalungile kusho ukuthi izingxenye zakho ngeke zilingane, kumise iphrojekthi yakho kuze kube yilapho usungathola i-valve efanele.

Uxhuma i-valve yebhola ku-PVC ngendlela eyodwa yezindlela ezimbili. Usebenzisa ukuxhumana okunentambo (i-NPT noma i-BSP) kumasistimu angase adinge ukuhlakazwa, noma uxhumo lwesokhethi (i-solvent weld) ukuze kuhlangane unomphela, okunamathiselwe ethe njo.

Isinyathelo sokuqala ngaso sonke isikhathi ukufanisa i-valve yakho nohlelo lwakho lwamapayipi. Uma amapayipi akho e-PVC esevele enawo amaphethelo anentambo yesilisa, udinga ivalve enentambo yesifazane. Kodwa emisebenzini eminingi emisha yokufaka amapayipi, ikakhulukazi ukuchelela noma amachibi, uzosebenzisa ama-socket valves kanye nosimende oncibilikayo. Ngihlala ngikuthola kuwusizo lapho ithimba likaBudi libonisa amakhasimende itafula ukuze acacise ukukhetha. Indlela ilawulwa yi-valve onayo. Awukwazi ukunamathisela i-valve enentambo noma uhlanganise i-valve yesokhethi. Indlela ejwayeleke kakhulu futhi ehlala njalo yokuxhumana kwe-PVC kuya ku-PVC yileisisekelo, nomai-solvent weld, indlela. Le nqubo ayigcini nje ngokunamathisela izingxenye ndawonye; ihlanganisa ngamakhemikhali i-valve nepayipi kube ucezu lwepulasitiki olulodwa, olungenamthungo, oluqine ngendlela emangalisayo futhi oluthembekile uma lwenziwe ngendlela efanele.

Ukuhlukaniswa Kwendlela Yokuxhuma

Ingabe ikhona indlela efanele yokufaka i-valve yebhola?

Ucabanga ukuthi i-valve isebenza ngendlela efanayo kunoma iyiphi indlela. Kodwa ukuyifaka ngomumo ongalungile kungakhawulela ukugeleza, kudale umsindo, noma kukwenze kungenzeki ukusevisa ngokuhamba kwesikhathi.

Yebo, kukhona indlela efanele. I-valve kufanele ifakwe nesibambo esifinyelelekayo, amantongomane enyunyana (ku-valve ye-union yeqiniso) abekwe ukuze asuswe kalula, futhi ahlale esendaweni evulekile ngesikhathi sokunamathisela.

Imininingwane eminingana emincane ihlukanisa ukufakwa okuphrofeshinali kokungafundi. Okokuqala,phatha orientation. Ngaphambi kokuba unamathisele noma yini, beka i-valve futhi uqiniseke ukuthi isibambo sinemvume eyanele ukuvula ama-degree angu-90 agcwele. Ngike ngabona ama-valve efakwe eduze kakhulu nodonga kangangokuthi isibambo singavuleka phakathi nendawo. Kuzwakala kulula, kodwa kuyiphutha elivamile. Okwesibili, kumavalvu ethu eNyunyana Yeqiniso, sifaka amantongomane amabili enyunyana. Lawa aklanyelwe ukuze ukwazi ukuwakhulula futhi uphakamise umzimba we-valve uwukhiphe epayipini lesevisi. Kufanele ufake ivalvu enendawo eyanele ukuze uxegise lamantongomane. Isinyathelo esibucayi kakhulu, nokho, isimo sevalvu ngesikhathi sokufakwa.

Isinyathelo Esibaluleke Kakhulu: Gcina I-Valve Ivuliwe

Uma unamathisela (i-solvent welding) i-valve yesokhethi, i-valvekufaneleube sesimweni esivuleke ngokugcwele. Ama-solvents ku-primer nosimende aklanyelwe ukuncibilikisa i-PVC. Uma i-valve ivaliwe, lezi zincibilikisi zingavaleleka ngaphakathi komzimba we-valve bese zishisela ibhola ngamakhemikhali emgodini wangaphakathi. I-valve izovalwa unomphela. Ngitshela uBudi ukuthi lokhu kuyimbangela yokuqala "yokuhluleka kwe-valve entsha." Akusona isici se-valve; kuyiphutha lokufaka elingagwemeka 100%.

Indlela yokunamathisela i-valve yebhola ye-PVC?

Usebenzisa i-glue futhi unamathele izingxenye ndawonye, ​​kodwa ilunga lihluleka ngaphansi kwengcindezi. Lokhu kwenzeka ngoba "ukunamathisela" empeleni kuyinqubo yamakhemikhali edinga izinyathelo ezithile.

Ukuze unamathisele kahle i-valve yebhola ye-PVC, kufanele usebenzise i-primer yezinyathelo ezimbili kanye nendlela kasimende. Lokhu kuhilela ukuhlanza, ukusebenzisa i-primer purple kuzo zombili izindawo, bese usebenzisa usimende we-PVC ngaphambi kokuzihlanganisa nge-twist.

Le nqubo ibizwa ngokuthi i-solvent welding, futhi yakha isibopho esinamandla kunepayipi ngokwalo. Ukweqa izinyathelo kuyisiqinisekiso sokuvuza okuzayo. Nansi inqubo esiqeqesha abasabalalisi beBudi ukuthi bayilandele:

1. Dry Fit Okokuqala.Qinisekisa ukuthi ipayipi iphuma ngaphakathi ngaphakathi kwesokhethi yevalvu.
2. Hlanza Izingxenye Zombili.Sebenzisa indwangu ehlanzekile, eyomile ukuze usule noma yikuphi ukungcola noma umswakama ovela ngaphandle kwepayipi nangaphakathi kwesokhethi yevalvu.
3. Faka isicelo sokuqala.Sebenzisa i-dauber ukufaka ijazi elikhululekile le-primer ye-PVC ngaphandle kokuphela kwepayipi nangaphakathi kwesokhethi. I-primer ihlanza ubuso ngamakhemikhali futhi iqala ukuthambisa ipulasitiki. Lesi isinyathelo eseqiwe kakhulu nesibaluleke kakhulu.
4. Faka usimende.Ngenkathi i-primer isemanzi, sebenzisa ungqimba olulinganayo lukasimende we-PVC phezu kwezindawo ezikhonjiwe. Ungasebenzisi kakhulu, kodwa qinisekisa ukutholakala okugcwele.
5. Xhuma futhi Twist.Ngokushesha phushela ipayipi kusokhethi lize liphume ezansi. Njengoba uphusha, yinike ithuba lekota. Lokhu kunyakaza kusabalalisa usimende ngokulinganayo futhi kususe noma yimaphi amabhamuza omoya avaleleke.
6. Bamba Ukwelapha.Bamba ilunga liqine endaweni engaba yimizuzwana engama-30 ukuvimbela ipayipi ukuthi lihlehle liphume. Ungalithinti noma uphazamise ilunga okungenani imizuzu eyi-15, futhi ulivumele ukuthi lelaphe ngokugcwele ngokwemiyalelo yomkhiqizi usimende ngaphambi kokucindezela uhlelo.

Uyenza kanjani i-valve yebhola ye-PVC ibe lula?

I-valve yakho entsha sha iqinile, futhi ukhathazekile ngokunqamula isibambo. Lokhu kuqina kungakwenza ucabange ukuthi i-valve inesici kuyilapho empeleni kuwuphawu lwekhwalithi.

Ivalvu ye-PVC entsha, yekhwalithi ephezulu iqinile ngoba izihlalo zayo ze-PTFE zenza isigxivizo esiphelele, esiqinile ngokumelene nebhola. Ukuze wenze kube lula, sebenzisa isikrufu kunathi eliyisikwele esisekelweni sesibambo ukuze uthole amandla angcono ukuze ulihlephule.

Ngithola lo mbuzo ngaso sonke isikhathi. Amakhasimende athola iPntek yethuama-valvefuthi bathi zinzima kakhulu ukuzijika. Lokhu ngamabomu. Izindandatho ezimhlophe ngaphakathi, izihlalo ze-PTFE, zibunjwe ngokunemba ukuze zenze uphawu oluqinile lwebhamuza. Lokho kuqina yikho okuvimbela ukuvuza. Ama-valve ashibhile anezimpawu ezixegayo aphenduka kalula, kodwa abuye ahluleke ngokushesha. Cabanga ngakho njengepheya elisha lezicathulo zesikhumba; zidinga ukugqekezwa. Indlela engcono kakhulu yokwenza lokhu ukusebenzisa isikrufu esincane esilungisekayo engxenyeni ewugqinsi, eyisikwele ye-shaft yesibambo, kwesokudla esisekelweni. Lokhu kukunikeza amandla amaningi ngaphandle kokubeka ingcindezi kusibambo se-T uqobo. Ngemva kokuyivula nokuyivala izikhathi ezimbalwa, izoba bushelelezi kakhulu.Ungalokothi usebenzise i-WD-40 noma ezinye izithambisi ezisekelwe kuwoyela.Le mikhiqizo ingahlasela futhi yenze buthaka ipulasitiki ye-PVC kanye nezimpawu ze-EPDM O-ring, okubangela ukuthi i-valve ihluleke ngokuhamba kwesikhathi.

Isiphetho

Ukufakwa okufanele, kusetshenziswa indlela yokuxhumana efanele, umumo, kanye nenqubo yokunamathisela, iyona ndlela kuphela yokuqinisekisa aI-valve yebhola ye-PVCinikeza impilo yesevisi ende, ethembekile, engavuzi.
