Ubheka ivalvu ye-PVC bese ubona igama elithi “isokhethi end.” Awuqiniseki ukuthi lokhu ukuxhumana okulungile kwamapayipi akho, futhi uku-oda uhlobo olungalungile kusho ukubambezeleka kwephrojekthi.

Isokhethi yevalvu ye-PVC iyisiphetho sesifazane sevalvu, eyenzelwe ukwamukela ipayipi le-PVC. Yakha uphawu oluhlala njalo, olungangeni manzi kusetshenziswa usimende we-solvent (glue), okwenza kube uhlobo lokuxhuma oluvame kakhulu ezinhlelweni ze-PVC.

Leli gama elilula, elithi “isokhethi,” ngezinye izikhathi lingabangela ukudideka, ikakhulukazi uma ubona nezinketho ezifana nokuthi “uchungechunge.” Kodwa ukukhetha uhlobo lokuxhuma olufanele kungenye yezinqumo ezibaluleke kakhulu zesistimu engavuzi. Ngivame ukuba nale ngxoxo nabalingani bami abanjengoBudi e-Indonesia. Udinga ukunikeza isiqondiso esicacile kumakhasimende akhe, osonkontileka kanye nabaphayi bamapayipi. Kudingeka bazi ukuthiuxhumano lwesokhethi, uma kwenziwe kahle, akulona nje uxhumano—luyi-ukushintshwa okuhlala njaloAke sichaze kahle ukuthi iyini isokhethi nokuthi kungani ibaluleke kangaka.

Iyini i-socket ye-valve esetshenziselwa yona?

Udinga ukuhlanganisa i-valve nepayipi unomphela. Ukuxhumeka okubuthakathaka kungaholela ekuvuzeni okubi kakhulu kanye nokulungiswa okubizayo esikhathini esizayo, okonakalisa idumela lephrojekthi yakho futhi kukubize imali.

Isokhethi yevalvu isetshenziselwa ukudala uxhumano oluqinile, oluhlala njalo, nolungavuzi phakathi kwevalvu nepayipi le-PVC. Ipayipi lifakwa kusokhethi bese lishintshwa ngamakhemikhali kusetshenziswa usimende we-solvent, kwakha ingxenye eyodwa eqinile.

Umlingo wangempela wokuxhumeka kwesokhethi inqubo ebizwa ngokuthiukushisela i-solvent. Akufani nokusebenzisa iglue evamile ukunamathelisa izinto ezimbili ndawonye. I-solvent cement empeleni incibilikisa ungqimba oluncane lwe-PVC kokubili odongeni lwangaphandle lwepayipi kanye nodonga lwangaphakathi lwe-socket ye-valve. Uma uzicindezela ndawonye, ​​lezi zindawo ezimbili ezincibilikisiwe ziyahlangana. Njengoba i-solvent iphela, i-PVC iyaqina ibe yingcezu eyodwa yepulasitiki, engenamthungo, futhi eqinile kakhulu. Lokhu kudala isibopho esiqinile njengepayipi uqobo, okuqinisekisa ukuthi ingakwazi ukubhekana nokucindezela futhi ngeke ivuze noma ikhululeke ngokuhamba kwesikhathi. Kuyindinganiso yegolide yokuhlala unomphelaUkufakwa kwe-PVC.

Inqubo Yokushisela I-Solvent

Ukuze uthole leso sibopho esiphelele nesingenakuvuza, kufanele ulandele izinyathelo ngokucophelela.

1. Sika futhi Ususe I-Burr:Thola ukusika okuhlanzekile, okuyisikwele epayipini. Khuhla noma yiziphi izimbobo zepulasitiki ngaphakathi nangaphandle kwesiphelo sepayipi.
2. Ukuhlanzeka Nokugqama:Sebenzisa isihlanzi bese usebenzisa i-primer kokubili ngaphandle kwepayipi nangaphakathi kwesokhethi. Lesi sinyathelo sibalulekile; sisusa amafutha futhi sithambisa i-PVC ukuze kube nokushibilika okungcono.
3. Faka usimende:Uma usebenza ngokushesha, faka ungqimba olulinganayo lwesimende se-solvent ngaphandle kwepayipi kanye nongqimba olulula ngaphakathi kwesokhethi.
4. Faka bese Ujika:Cindezela ipayipi ngokuqinile ungene kusokhethi uze ufike esitobhini. Lijike kancane kancane ukuze usakaze usimende ngokulinganayo bese ulibamba endaweni yalo cishe imizuzwana engama-30 ukuze uvimbele ipayipi ukuthi lingaphumi liphume.

I-valve ye-PVC isetshenziselwa ini?

Udinga ukulawula ukugeleza kwamanzi epayipini. Ngaphandle kwevalvu ethembekile, awunandlela yokwenza ukulungisa, ukuhlukanisa izingxenye, noma ngisho nokuvala ukugeleza kwamanzi esimweni esiphuthumayo.

Ivalvu ye-PVC isetshenziselwa ukuqala, ukumisa, noma ukulawula ukugeleza koketshezi ohlelweni lwamapayipi e-PVC. Ibalulekile ekulawuleni amanzi ezisetshenziswayo njengokunisela, amachibi okubhukuda, ukwelashwa kwamanzi, kanye nokufakwa kwamapayipi ezindaweni zokuhlala.

Amavalvu e-PVC ayizindawo ezibalulekile zokulawula kunoma yiluphi uhlelo lwamanzi. Athandwa kakhulu ngoba izinto ze-PVC ngokwazo ziyamelana nokugqwala nokugqwala, okwenza kube kuhle kakhulu ekuphatheni amanzi kanye namakhemikhali amaningi. Futhi ilula futhi ingabizi kakhulu kunezinye izindlela zensimbi. YingakhoAmavalvu e-PVCyizona ezikhethwa kakhulu kumakhasimende amaningi abalingani bethu, kusukela kubalimi abasungula ukunisela kuya kosonkontileka abakha izindlu ezintsha. Imisebenzi ehlukene idinga izinhlobo ezahlukene zokulawula, ngakho-ke sakha izinhlobo eziningana zamavalvu. Ngayinye yenzelwe injongo ethile ngaphakathi kohlelo lwamapayipi.

Izinhlobo Ezivamile Zama-PVC Valve

Ukuqonda i-valve efanele yomsebenzi kuyisihluthulelo sesistimu eklanywe kahle.

Uhlobo lwe-Valve	Ukusetshenziswa Okuyinhloko	Indlela Esebenza Ngayo
I-Ball Valve	Ukulawula okusheshayo kokuvula/ukuvala.	Ibhola elinembobo lijikeleza ama-degree angu-90 ukuvula noma ukuvala umugqa ngokushesha.
Hlola i-Valve	Kuvimbela ukugeleza kwegazi emuva.	I-flap noma ibhola livumela amanzi ukuthi ageleze ohlangothini olulodwa kuphela. Livikela amaphampu.
I-Butterfly Valve	Vula/Cima amapayipi amakhulu.	Idiski ngaphakathi kwepayipi iyajikeleza ukulawula ukugeleza. Ivame ukusetshenziswa emapayipini angu-3″ nangaphezulu.
I-Valve yeSango	Ukulawula Kokuvula/Ukuvala Okuhamba Kancane.	Isango eliyisicaba liyashelela kancane kancane liye phezulu naphansi. Akuvamile kakhulu

Iyini i-socket ye-PVC esetshenziselwa yona?

Udinga ukuhlanganisa izingcezu ezimbili zepayipi le-PVC noma uxhume ipayipi endaweni yokuhlanganisa. Ukulungisa leli lunga kusho ukuvuza, ukucindezela okuphansi, kanye nokudinga ukusika nokuphinda umsebenzi.

Isokhethi le-PVC liwumgodi wesifazane kunoma yikuphi ukufakwa kwe-PVC (njenge-coupling, i-elbow, noma i-tee). Lakhelwe ukwamukela ipayipi le-PVC elingenalutho, okwenza i-joint ene-solvent cement.

Igama elithi “isokhethi” alisho kuphela ama-valve. Liyigama elijwayelekile lokuxhumeka okuvamile kwabesifazane cishe kuzo zonke izinto zokufakelwa ze-PVC. Kungakhathaliseki ukuthi usebenzisa into yokuhlanganisa ukushintsha indlela ipayipi eliqondiswa ngayo noma ivalvu ukulawula ukugeleza kwayo, ingxenye yesokhethi isebenza ngendlela efanayo: yamukela ipayipi ukudala ijoyinti elihlanganisiwe nge-solvent. Umehluko wangempela kuphela yilokho okwenziwa yi-component. Into yokuhlanganisa imane ixhuma ipayipi, kuyilapho ivalvu ixhuma ipayipi.futhiinezela umsebenzi wokulawula. Ikhwalithi yalesi sokhethi ibaluleke kakhulu. Kwa-Pntek, izikhunta zethu zenzelwe ukubekezelelana okuqinile kakhulu. Lokhu kuqinisekisa ukulingana kahle nepayipi, okubaluleke kakhulu ekushiseni okuqinile nokuthembekile okungeke kwehluleke ngaphansi kwengcindezi.

Ukufakwa Kwesokhethi vs. Amavalvu

Zombili zisebenzisa amasokhethi ukuze zixhumane, kodwa imisebenzi yazo ohlelweni ihlukile.

Uhlobo Lwezinto	Umsebenzi
Ukuxhumanisa	Ixhuma amapayipi amabili ngendlela eqondile.
Indololwane (90° noma 45°)	Ishintsha indlela okuhamba ngayo ipayipi.
I-T-shirt	Idala i-T-junction ukuze ihlukanise umugqa omusha kusukela ekugijimeni okuyinhloko.
Isivalo	Ivala ukuphela komgudu wepayipi unomphela.
Ivalvu	Ixhuma epayipini futhi ilawula ukugeleza kwamanzi (ukuvula/ukuvala, ukulawulwa).

Kusho ukuthini ukuthi “isokhethi” ezinhlanganisweni ze-PVC?

Ubona elithi “socket,” “slip,” “hub,” kanye nelithi “female end” elisetshenziswa ukuchaza ukuxhumana okufanayo. Amagama ahlukene ayadida, futhi ukhathazeka ngokuchaza kabi incazelo yomkhiqizo noma i-invoyisi.

Kuma-fitting e-PVC, elithi “socket” lisho ukuphela kwesifazane okwenzelwe ukuxhumana kwe-solvent weld. Lifana nokuthi “slip” noma “hub.” Lichaza umgodi ovalwe lapho kufakwa khona ucezu lwepayipi elingenalutho bese lunamatheliswa.

Wonke la magama asho into efanayo.“Isokhethi”igama lobuchwepheshe elivame kakhulu. Igama elithi “Slip” livame ukusetshenziswa eNyakatho Melika ngoba ipayipi“ama-slip”ngaphambi kokunamathelisa.“Ihabhu”igama elidala kodwa lisasetshenziswa. Wonke abhekisela ohlotsheni olufanayo lokuxhumana, oluhluke ngokuphelele ekuxhumaneni okunezintambo. Ukuqonda lo mehluko kungenye yezinto zokuqala engizifundisa abalingani abasha. Uma wazi umehluko, ungakha izinhlelo eziqinile futhi ezilungisekayo lapho kudingeka khona.

Isokhethi vs. Intambo: Izinhlobo Ezimbili Eziyinhloko Zokuxhumana

Ukukhetha uhlobo lokuxhuma olufanele kubalulekile ukuze kube nephrojekthi ephumelelayo yokuxhuma amapayipi.

Uhlobo Lokuxhumeka	Indlela Esebenza Ngayo	Okuhle Kakhulu Ku…
Isokhethi (Isilayidi/Ihabhu)	Isebenzisa usimende we-solvent ukuze ibophe unomphela, ohlanganisiwe.	Ukufakwa okuhlala njalo, izinhlelo ezingaphansi komhlaba, imigqa enomfutho ophezulu lapho udinga khona amandla aphezulu futhi kungabikho ukuvuza.
Okunentambo (FPT/MPT)	Imicu yesilisa neyesifazane iyahlanganiswa, ivalwe ngeteyipu ye-PTFE.	Izindawo zokuxhuma kumaphampu, izihlungi, amathangi, noma kuphi lapho ungadinga khona ukuqaqa uhlelo ukuze lulungiswe.

Akufanele neze usebenzise usimende we-solvent ezintweni zokufakelwa ezinezintambo. Amakhemikhali angenza ipulasitiki iqhekeke futhi ibangele ukuthi iqhekeke ngaphansi kwengcindezi yokuqina. Leli yiphutha elivamile elingaholela ekwehlulekeni kohlelo.

Isiphetho

Isokhethi yevalvu ye-PVC iyindlela evame kakhulu nethembekile yokuxhuma ivalvu epayipini. Ukuqonda lokhu kuxhumana okuyisisekelo nokuthi ungakushisela kanjani kahle kuyisihluthulelo sokwakha izinhlelo eziqinile.
