Uthembele kwivalvu yeplastiki elula ukulawula ukuhamba kwamanzi, kodwa ngaba wakha wazibuza ukuba yenziwa njani? Ukuba ivalvu ayisebenzi kakuhle ngenxa yokwenziwa kakubi, inokubangela ukuvuza okukhulu, umonakalo kwipropathi, kunye nokulahlekelwa kukuthembana kwabathengi bakho.

Iivalvu zebhola zePVC zenziwa ngokuyintloko ngokubumba ngenaliti. Izinto eziluhlaza zePVC ziyanyibilika zize zifakwe phantsi koxinzelelo oluphezulu kwiimold zentsimbi ukuze zenze umzimba, ibhola, isiqu, kunye nesiphatho. Ezi zinto emva koko zidityaniswe nezihlalo zeTPE okanye zeEPDM kunye nezitywino.

Nanini na xa uBudi etyelela umzi-mveliso wethu, ndiyaqinisekisa ukuba ubona indawo yethu yokubumba inaliti kuqala. Ukubona oomatshini abaninzi abazenzekelayo, ukukhwaza okuchanekileyo kwe-hydraulics, kunye namacandelo amatsha e-PVC avela kwibhanti yokuhambisa imithwalo kuxela ibali elinamandla. Libali malunga nokungaguquguquki kunye nolawulo lomgangatho. Ukudala indlela ethembekileyo yokubumba i-injection molding.Ivalvu yebhola yePVCayikokuba nomatshini nje kuphela; imalunga nomgangatho weenkuni zentsimbi, ubumsulwa bezinto ezisetyenzisiweyo, kunye nokuchaneka kwenkqubo yokuhlanganisa. Ukuqonda indlela ezi nxalenye ezidibana ngayo kunika amaqabane ethu ukuzithemba kokuba abathengisi nje inxalenye yeplastiki, kodwa iyinxalenye yokuthembeka okwenziwe ngobunjineli.

Zenziwa njani iivalvu zebhola?

Ubona ivalvu yebhola egqityiweyo, kodwa ukwenziwa kwayo kubonakala ngathi yibhokisi emnyama. Ngaphandle kokwazi inkqubo, kunzima ukubona umahluko phakathi kwevalvu esemgangathweni ophezulu kunye nexabiso eliphantsi, elingathembekanga.

Iivalvu zebhola zenziwa ngokwenza izinto ezahlukeneyo—umzimba, ibhola, isiqu, izihlalo, kunye nesiphatho—zize emva koko zihlanganiswe. Le ndlela iyahluka ngokwezinto ezenziwe ngazo: iindawo zeplastiki zibunjwa ngenaliti, ngelixa iindawo zesinyithi zihlala zenziwe okanye zenziwe ngesinyithi ngaphambi kokuba zenziwe ngomatshini.

Makhe sijonge inkqubo eqhelekileyo yevalvu yebhola, nokuba yeplastiki okanye yesinyithi. Konke malunga nokudala iindawo nokuzidibanisa ngokuchanekileyo. Iindawo ezimbini eziphambili zevalvu eziqulathe uxinzelelo ngumzimba kunye nebhola. Kwiivalvu zesinyithi, umzimba udla ngokwenziwaukuphosa(ukugalela isinyithi esinyibilikisiweyo kwisikhunta) okanyeukubumba(ukubumba isinyithi ngoxinzelelo olukhulu). Emva koko, idlula kwi-machining ebanzi ukuze idale iindawo ezigudileyo kunye nemisonto echanekileyo. Ibhola ngokwayo kufuneka ibe yingqukuva kwaye ipholishwe ngokugqibeleleyo ukuze idale isitywino esihle. Kwiivalvu zeplastiki ezifana nezethu zePVC, sisebenzisaukubumba ngenalitiLe nkqubo ikhawuleza kakhulu kwaye isenza sikwazi ukudala iimilo ezintsonkothileyo ngokuchanekileyo okukhulu kanye ngaphandle kwesikhunta, nto leyo enciphisa ukwenziwa kwemishini eyongezelelweyo. Nje ukuba zonke iindawo zenziwe, zihlanganiswa ngononophelo ngezitywino ngokulandelelana okuthile ukuqinisekisa ukuba zisebenza kakuhle kwaye zitywinwe kakuhle.

Ukuhlanganiswa kweValve yeBhola yePntek PVC

Inyathelo	Isenzo	Injongo
1. Ukufakwa kwesihlalo	Iiringi ze-TPE okanye ze-EPDM O-rings (izihlalo) zifakwa kwiinxalenye zomzimba wevalvu.	Ukwenza isitywino esiqinileyo esijikeleze ibhola.
2. Ukubekwa kweBhola kunye neSikhondo	Ibhola ifakwa, kwaye isiqu sityhalelwa emzimbeni singene ebholeni.	Isiqu sivumela isiphatho ukuba sijike ibhola.
3. Ukudibana komzimba	Iziqingatha zomzimba zidibene. Sisebenzisa i-ultrasonic welding ukuze sidibanise isigxina okanye i-threaded union kwiivalvu ezilungisekayo.	Ukuvala ibhola nokwenza indawo eqinileyo nengavuziyo.
4. Isincamathiselo seSiphatho	Isiphatho sinamathele phezulu kwesiqu, sidla ngokuxhonywa ngesikrufu.	Ukubonelela ngenkxaso-mali yokusebenza okulula kwekota.
5. Uvavanyo loxinzelelo	Ivalvu nganye ivavanywa ngomoya namanzi ukuze kubonakale ukuba ayivuzi na.	Ukuqinisekisa ukuthembeka kwe-100% ngaphambi kokuba iphume kumzi-mveliso.

Yintoni ngaphakathi kwevalvu yebhola yePVC?

Ujika isiphatho aze amanzi ayeke, kodwa kwenzeka ntoni ngaphakathi? Ukungaqondi indlela esebenza ngayo ngaphakathi kwenza kube nzima ukusombulula iingxaki okanye ukuchaza ixabiso lemveliso kumenzi-mveliso.

Ingaphakathi levalvu yebhola yePVC inebhola eqinileyo, engqukuva enembobo ngaphakathi kwayo (imbobo). Le bhola iphakathi kwezitywini ezimbini ezithambileyo, ezimile okwesangqa ezibizwa ngokuba zizihlalo kwaye iqhagamshelwe kwisiqu, esijikajikayo.

Cinga ngayo njengomatshini olula kakhulu. Izinto eziphambili yibhola, izihlalo, kunye nesiqu. Xa ujika isiphatho, sijikeleza isiqu. Isiqu siqhagamshelwe kwibhola, ngoko ke nebhola iyajika. Kwimeko 'evulekileyo', umngxuma ebholeni uhambelana nombhobho, uvumela amanzi ukuba ahambe ngqo ngaphandle kokuthintela. Le yinzuzo enkulu kunezinye iintlobo zeevalvu ezinokunciphisa ukuhamba. Xa ujika isiphatho ngekota-turn (90 degrees), inxalenye eqinileyo yebhola iyajikeleza ukuvala ukuvulwa, icinezele ngokuqinileyo kwizihlalo ezithambileyo kumacala omabini. Ezi zihlalo, ezenziwe ngezinto eziguquguqukayo ezifana ne-TPE okanye i-EPDM, zenza uphawu olugqibeleleyo olumisa ukuhamba kwamanzi ngokupheleleyo. Ukulula kwale ndlela yokwenza yiyo eyenza ivalvu yebhola ithembeke kwaye ithandwe.

Iyintoni inkqubo yokwenziwa kweevalvu zeplastiki?

Uyazi ukuba iivalvu zeplastiki zivela kumzi-mveliso, kodwa ziyifumana njani imilo yazo? Ukwazi le nkqubo kukunceda uqonde ukuba kutheni umgangatho wokungunda kunye nezinto ezikrwada zibaluleke kangaka kumandla emveliso yokugqibela.

Inkqubo ephambili yokwenziwa kweevalvu zeplastiki kukubumba ngenaliti. Oku kubandakanya ukunyibilikisa iigranule zeplastiki zibe lulwelo, ukufaka le plastiki ilulwelo kwisikhunta sentsimbi esenziwe ngomatshini phantsi koxinzelelo oluphezulu, uze uyipholise ukuze ibe yinxalenye eqinileyo.

Mandikucacisele indlela yokubumba i-injection, kuba le yeyona nto iphambili ekusebenzeni kwethu kwePntek.

1. Ukulungiswa kwezinto:Siqala nge-resin ye-PVC eluhlaza ekumgangatho ophezulu. Sixuba oku kunye nezongezo ezifana neziqinisi (ukuqinisekisa ukuqina) kunye nemibala (ukuqinisekisa umbala), size siyomise ukuze kususwe naluphi na umswakama onokubangela iziphene.

2. Ukunyibilika:Iigranule zePVC zifakwa kwibhareli enkulu eshushu ene-screw ngaphakathi. Njengoko i-screw ijika, ityhala iplastiki phambili, iyifudumeza kwaye iyinyibilikise ibe yimeko efanayo, yolwelo, njengobusi obukhulu.

3. Inaliti:I-mold, eyiziqingatha ezibini zesixhobo sentsimbi, ivalwa ngamandla amakhulu. Iplastiki enyibilikisiweyo emva koko ifakwe emngxunyeni we-mold ngoxinzelelo oluphezulu kakhulu. Oku kuqinisekisa ukuba yonke ikona ye-mold iyazaliswa.

4. Ukupholisa kunye nokuKhupha:Amanzi ajikeleza ngemijelo kwi-mold ukuze ayipholise ngokukhawuleza. Iplastiki iyaqina ibe yimo yokugqibela. I-mold emva koko iyavuleka, kwaye ii-ejector pins zityhala inxalenye egqityiweyo ngaphandle.

Lo mjikelo wonke ungathatha ngaphantsi komzuzu. Umgangatho wevalvu yokugqibela uxhomekeke ngokupheleleyo kwisikhunta esilungileyo, izixhobo ezicocekileyo, kunye nolawulo oluchanekileyo lobushushu kunye noxinzelelo.

Yintoni umahluko phakathi kweevalvu zebhola zePVC kunye ne-UPVC?

Uyabona amagama asetyenziswa njenge-PVC kunye ne-UPVC, ngamanye amaxesha ngokutshintshana, kwaye kuyadida. Kufuneka wazi ukuba ziyafana na okanye kukho umahluko wokwenyani ochaphazela isigqibo sakho sokuthenga.

Kwishishini lemibhobho yanamhlanje, akukho mahluko. I-UPVC (i-Unplasticized Polyvinyl Chloride) ligama elichanekileyo ngokwetekhnoloji lezinto eziqinileyo ezisetyenziswa kwimibhobho nakwiivalvu. I-PVC ligama eliqhelekileyo nelifutshane elisetyenziswa ngumntu wonke kwimveliso efanayo.

Lo ngumbuzo omhle kakhulu kuba ubangela ukudideka okukhulu okungeyomfuneko kwimarike. Kwiminyaka emininzi eyadlulayo, igama elithi “PVC” ngamanye amaxesha linokubhekisa kwiintlobo zePVC eziguquguqukayo ezazine-plasticizers ezongeziweyo (cinga ngepayipi yegadi). Ukwahlula izinto eziqinileyo neziqinileyo ezisetyenziselwa imibhobho, eli shishini lamkela igama elithi “UPVC,” elithi “U” limele “i-unplasticized.” Nangona kunjalo, namhlanje, xa umntu okwishishini lemibhobho okanye lokwakha esithi “ipayipi yePVC” okanye “ivalvu yebhola yePVC,” uhlala ebhekisa kwizinto eziqinileyo nezingenaplastiki. Amagama aye aba yinto enye xa esetyenziswa. Ndixelela uBudi kunye neqela lakhe ukuba basebenzise igama elisetyenziswa ngabathengi babo. Nokuba niyibiza ngokuba yiPVC okanye yiUPVC, nifumana izinto ezifanayo ezinamandla, ezinokuthenjwa, nezinganyangekiyo kwivalvu zenu zebhola. KwaPntek, sisebenzisa igama elithi “PVC” kuba lelona gama liqhelekileyo neliqondakala lula kwihlabathi liphela.

Isiphelo

Iivalvu zebhola zePVCzenziwe ngenkqubo echanekileyo yokubumba ngenaliti kunye nokuhlanganiswa ngononophelo. Ukuqonda le nkqubo kuqinisekisa ukuba izixhobo ezisemgangathweni kunye nokuveliswa zibalulekile kwivalvu ethembekileyo nehlala ixesha elide.
