6. I-flange ephakathi (unxibelelwano phakathi komzimba wevalvu nomzimba wasekhohlo) ayinasakhiwo sokuvuza. Unxibelelwano phakathi komzimba wevalvu nomzimba wasekhohlo luvalwe ngee-gaskets. Ukuze kuthintelwe ukuvuza okubangelwa ngumlilo, ubushushu obuphezulu okanye ukungcangcazela, yenzelwe ngokukodwa. Umzimba wevalvu unxibelelana nesinyithi-isinyithi kumzimba wasekhohlo ukuze wenze i-flange esisigxina yokungena ukuqinisekisa ukuba akukho kuvuza.

 

7. Isakhiwo sokukhusela umlilo Xa kwenzeka ingozi yomlilo, izinto ezingezizo ezesinyithi ezifana nezihlalo zeevalvu kunye nezizalisi ziya kutsha, kwaye inani elikhulu lezinto ezivuzayo zinokukhuthaza ngakumbi umlilo. Isakhiwo sevalvu esingatshiyo sinokuthintela ukuvuza okukhulu okuphakathi. Emva komlilo, iindawo ezivuzayo (umzimba webhola kunye nevalvu, isiqu sevalvu kunye nomzimba wevalvu, iflange ephakathi) zenzelwe ukuba zinxibelelane nesinyithi ukuhlangabezana neemfuno zokukhusela umlilo. Njengoko kubonisiwe kumfanekiso, xa isihlalo sevalvu sitshisiwe, ibhola iya kunxibelelana ngqo nomphezulu wesinyithi womzimba wevalvu phantsi koxinzelelo, ngaloo ndlela ithintela inani elikhulu lezinto ezivuzayo ekuphumeni kwisihlalo sevalvu esitshisiweyo.

 

2. Uvavanyo loxinzelelo-lobushushu

 

Uvavanyo loxinzelelo kunye nobushushu bevalvu yebhola aluhambelani nje kuphela nezinto zeqokobhe, kodwa lukwanxulumene ngakumbi nezinto zokutywina ezifana nesihlalo sevalvu, ukupakisha kunye negasket. Itywina lingaba zizinto zepolymer, i-asbestos okanye irabha. Ukukhethwa kwezinto zokutywina kuxhomekeke kulwakhiwo oluphakathi, ubushushu bokusebenza, uxinzelelo lokusebenza kunye nesantya sokuhamba kwevalvu.

 

Kwiimeko zokusebenza ezahlukeneyo ezingaqikelelweyo, kunzima kakhulu ukumisela ngokuchanekileyo umlinganiselo woxinzelelo-ubushushu bevalvu. Ngokusekelwe kumava ethu okuvelisa iivalvu ixesha elide kunye nengxelo exabisekileyo evela kubathengi, silapha ukukunika umlinganiselo woxinzelelo-ubushushu bevalvu phantsi kweemeko zokusebenza ezizinzileyo.
