Pontšo ea Sehlahisoa
Molemo oa Sehlahisoa
Valve ea rona e na le botenya bo tloaelehileng ho latela GB26640, e etsa hore e khone ho tšoara khatello e phahameng ha ho hlokahala.
Setulo sa rona sa li-valve se sebelisa rabara ea tlhaho e tsoang kantle ho naha, e nang le rabara e fetang 50% ka hare. Setulo se na le thepa e ntle ea elasticity, e nang le bophelo bo bolelele ba tšebeletso. E ka buleha le ho koaloa makhetlo a fetang 10,000 ntle le tšenyo ea setulo.
Setulo sa valve se nang le 3 bushing le 3 O ring, se thusa ho tšehetsa kutu le ho tiisa ho tiisoa.
'Mele oa valve o sebelisa phofo e phahameng ea sekhomaretsi epoxy resin, e o thusa ho khomarela' mele ka mor'a ho qhibiliha.
Liboutu le linate li sebelisa thepa ea SS304, e nang le bokhoni bo phahameng ba ho sireletsa mafome.
Pini ea li-valve tsa butterfly e sebelisa mofuta oa modulation, matla a phahameng, e thibelang ho roala le khokahano e sireletsehileng.

Ex ia
- Ex: E bontša hore thepa e etselitsoe ho sebelisoa libakeng tse phatlohang.
- ia: Boemo bo phahameng ka ho fetisisa ba ts'ireletso ea ts'ireletso ea kahare. E bolela hore sesebelisoa se etselitsoe ho thibela litlhase tsa mofuta ofe kapa ofe kapa mocheso o ka hotetsang sepakapaka se phatlohang, esita le tlas'a maemo a mabeli a phoso (mohlala, ho hlōleha ha lisebelisoa kapa tšenyo e ka ntle).
- Thepa e nang le"ee"lebitso le ka sebelisoa libakeng tse kotsi ka ho fetisisa, moo likhase tse phatlohang li lulang li le teng.
IIC
- Karolo ena ea tekanyo e hlalosa sehlopha sa khase seo thepa e tiisitsoeng ka sona. Lihlopha tsa khase li tloha ho IIA ho ea ho IIC, kaIICho ba matla ka ho fetisisa, ho aparela digase tse kotsi ka ho fetisisa.
- IIC: E loketse maemo a leholimo a nang lehydrogen, acetylene, kapa likhase tse phatlohang tse tšoanang. Likhase tsena ke tsona tse hotetsang habonolo, kahoo thepa e hloka ho finyella litekanyetso tse phahameng ka ho fetisisa tsa tšireletso.

- T6ho bolela hore mocheso o ka holimo o ke ke oa feta85°C (185°F), esita le boemong bo bobe ka ho fetisisa. Ena ke boemo bo thata ka ho fetisisa ba mocheso, bo netefatsang hore sesebelisoa se bolokehile hore se ka sebelisoa ho pota-pota esita le likhase tse nang le kutloelo-bohloko tse ka hotetsang ha li batla li le tlaase.
