Ama-valve ebhola aneziqephu ezimbilikuyisinqumo esidumile ezinhlelweni eziningi zezimboni nezohwebo, ikakhulukazi lapho kulawulwa ukugeleza koketshezi. Lawa ma-valve auhlobo lwe-valve yekota-turnesebenzisa ibhola elingenalutho, elinembobo, nelizungezayo ukuze lilawule ukuhamba kwamanzi, umoya, uwoyela, nolunye uketshezi oluhlukahlukene. Ngama-valve aneziqephu ezimbili zebhola, i-PVC iyinto evamile ngenxa yokuqina kwayo nokumelana nokugqwala.

Umsebenzi we-valve yebhola eneziqephu ezimbili ulula kodwa uyasebenza. Lapho isibambo se-valve siphendulwa, ibhola ngaphakathi kwevalvu liyazungeza ukuze livumele noma livimbele ukugeleza koketshezi. Lokhu kuyenza ilungele izinhlelo zokusebenza ezidinga ukulawula okunembayo kokugeleza. I-valve yebhola eneziqephu ezimbili nayo iklanyelwe ukuthi ibe lula ukuyigcina nokuyilungisa, iyenze ibe yisixazululo esingabizi kakhulu ezimbonini eziningi.

Kuma-valve e-PVC aneziqephu ezimbili zebhola, le nto inezinzuzo eziningi. I-PVC (noma i-polyvinyl chloride) iyimpahla ye-thermoplastic eyaziwa ngokumelana namakhemikhali okuhle kakhulu, okuyenza ilungele ukusetshenziswa lapho ama-valve ehlangana noketshezi oluhlukahlukene. Ngaphezu kwalokho,I-PVC ayisindi futhi kulula ukuyifaka nokubamba. Futhi iqinile ngokwedlulele, okwenza kube ukukhetha okuhlala isikhathi eside futhi okuthembekile kuma-valve aneziqephu ezimbili zebhola.

Omunye wemisebenzi eyinhloko ye-valve yebhola eneziqephu ezimbili ukunikeza ukuvala okuqinile. Umklamo we-valve udala uphawu oluvikelekile lapho luvaliwe, okuvimbela noma yikuphi ukuvuza koketshezi olulawulwayo. Lokhu kubalulekile ezinhlelweni lapho ukuvuza kubiza noma kuyingozi. Izinto ze-PVC ezisetshenziswa kuma-valve ebhola anezicucu ezimbili ziqinisekisa ukuthi i-valve ihlala ivalwe ngokuqinile isikhathi eside, ngisho nalapho ivezwe kumakhemikhali anokhahlo noma amazinga okushisa aphezulu.

Esinye isici esibalulekile se-valve yebhola eneziqephu ezimbili yikhono lokulawula ukugeleza kwamanzi. Ngokumane uphendule isibambo, izinga lokugeleza lingalungiswa ukuze lihlangabezane nezidingo ezithile zohlelo lokusebenza. Leli zinga lokulawula libalulekile ezimbonini eziningi, kusukela ezikhungweni zokuhlanza amanzi kuya ezindaweni zokwelashwa ngamakhemikhali. Izinto ze-PVC ezisetshenziswa kuma-valve ebhola aneziqephu ezimbili ziqinisekisa ukuthi zingakwazi ukuhlangabezana nezidingo zokulawula ukugeleza kwezinhlelo zokusebenza ezihlukahlukene.

Ama-valve aneziqephu ezimbili zebhola nawo anenzuzo yokuba lula ukuqaqa nokuwagcina. Lokhu kuyiqiniso ikakhulukazi kuma-valve ebhola aneziqephu ezimbili ze-PVC, lapho izinto ezingasindi futhi ezihlala isikhathi eside zenza imisebenzi yokulungisa nokulungisa ibe lula futhi ingabizi. Lokhu, kuhlanganiswe namandla ayo okuvala okuqinile kanye nokulawula ukugeleza, kwenza i-PVC ye-valve yebhola eneziqephu ezimbili ibe ukukhetha okuthembekile nokusebenzayo kwezinhlelo zokusebenza ezihlukahlukene.

Kafushane, umsebenzi we-valve yebhola eneziqephu ezimbili (ikakhulukazi eyodwa eyenziwe nge-PVC) ukunikeza ukuvala okuqinile, ukulawula ukugeleza koketshezi, futhi kube lula ukuyinakekela. Uma ulawula ukugeleza kwamanzi, umoya noma amakhemikhali, ama-valve amabhola amabili ayisinqumo esiguquguqukayo nesithembekile ezimbonini eziningi. Idizayini yayo elula kodwa ephumelelayo ehambisana nezinzuzo zezinto ezibonakalayo ze-PVC ziyenza ibe yisixazululo esifanelekile sezinhlelo zokusebenza ezihlukahlukene.
