Imfihlo yeBolt: Indlela uxinzelelo lweGasket oluxhomekeke ngayo kuBalo lweBolt

Imibhobho yentsimbi ethambileyo, ngenxa yokuba zinamandla aphezulu, ziqinile, kwaye ziyamelana nokugqwala, ziye zaba ngumsebenzi onzima wokuthutha ulwelo kwiindawo ezahlukeneyo, kuquka ukunikezelwa kwamanzi kamasipala, ukusasazwa kwamanzi kwimizi-mveliso, kunye neenkqubo zokukhusela umlilo. Isitshixo sokudibanisa le mibhobho kwinethiwekhi ethembekileyo sihlala sikwinto ebonakala ingabalulekanga kodwa ibalulekileyo: i-gasket yerabha kwindawo yokudibanisa i-flange.

Abathengi abaninzi beepayipi ze-DI bayakuqonda ukubaluleka kokukhetha iipayipi zesinyithi ezithambileyo ze-EN598 ezikumgangatho ophezulu, kodwa bahlala bengayinaki iinkcukacha zenkqubo yokutywina edibeneyo. Enyanisweni, amandla okuthwala uxinzelelo lwe-flange interface axhomekeke kungekuphela nje kubukhulu bodonga okanye kwizinto zombhobho wentsimbi ngokwawo, kodwa nakwimigangatho ye-gasket yerabha kunye nenani leebholithi eziyikhuselayo, ezidibanisa zombini zibe ngumgca wokugqibela nobaluleke kakhulu wokuzikhusela ukuze kusebenze umbhobho ngokukhuselekileyo.

Okokuqala, masiqonde i-gasket yerabha esetyenziswa kwiindawo zokudibanisa iiflange. Icinezelwe phakathi kweeflange ezimbini kwaye umsebenzi wayo ophambili ngulo:

• Ukutywina okusebenzayo: Phantsi kwesenzo sokulayisha kwangaphambili kwebholiti, iyaguquguquka ngendlela ethambileyo, izalise ukungalungelelani okuncinci kumphezulu wokutywina weflange kwaye ithintele ukuvuza kolwelo lwangaphakathi (amanzi, igesi, njl.njl.).
• Ukuhlawula ukuphambuka: Ukufunxa ukuphambuka okuncinci kwe-angular kunye nokulungiswa okubangelwa kukufakelwa okanye ukumiswa kwesiseko, ukuqinisekisa isitywina esithembekileyo.
• Ukunciphisa ukudambisa kunye nokungcangcazela: Ibonelela ngomlinganiselo othile wokungcangcazela kunye nokunciphisa ingxolo, inciphisa impembelelo yehammer yamanzi okanye ukuguquguquka koxinzelelo kwinkqubo yemibhobho.
• Iigasket zerabha ezikumgangatho ophezulu zihlala zenziwe ngezinto ezifana ne-EPDM okanye i-NBR. Zibonelela ngokumelana nemozulu okuhle kakhulu, ukumelana namanzi, kunye nokumelana nokucinezelwa, ukuqinisekisa ukusebenza okuzinzileyo kwexesha elide phantsi kweemeko zokusebenza ezinzima.

Kutheni iibholthi ezininzi zinyusa ukumelana noxinzelelo?

1. Ukudala uxinzelelo olufanayo nolwaneleyo lokutywina. Inani elikhulu leebholithi lenza amandla oxinzelelo axineneyo kwaye asasazwe ngokulinganayo kwiringi yeflange, ngaloo ndlela exhathisa uxinzelelo lwangaphakathi oluphezulu kwaye ethintela ukungaphumeleli kwegasket yendawo kunye nokuvuza okubangelwa luxinzelelo olungalinganiyo.
2. Ukuqina kweflange kunye nokumelana nokugoba. Iibholithi ezingaphezulu zibonelela "ngendawo yokuxhasa" exineneyo yeflange, nto leyo ephucula kakhulu ukuqina kwayo iyonke kunye nokumelana nokugoba. Oku kuqinisekisa ucinezelo olufanayo lwegasket kuyo yonke indawo yokutywina, kugcina itywina nokuba iphantsi koxinzelelo oluphezulu.
3. Uyilo luhambelana ngokungqongqo nemigangatho yamazwe ngamazwe efana ne-ISO 2531 kunye ne-EN 545. Le migangatho ichaza ngokucacileyo inani lemingxuma yebholiti kunye neenkcukacha zebholiti kwiidayamitha ezahlukeneyo zepayipi (DN) kunye novavanyo loxinzelelo (PN).Umzekelo, iflange ye-DN100 PN10 inokuba neebholithi ezine. Iflange ye-DN100 PN16 inokuba neebholithi ezisibhozo. Iflange ye-DN300 PN16 ingadinga iibholiti ezili-12 okanye ezili-16.

Amanqanaba aphezulu oxinzelelo lokusebenza afuna inani elikhulu leebholithi ukuqinisekisa uqhagamshelo olukhuselekileyo.
