1. kwiqondo lokushisa kunye noxinzelelo oluphantsi, khetha i-gasket ye-non-metal ethambileyo, uxinzelelo oluphakathi kunye nobushushu obuphezulu, khetha i-metal kunye ne-non-metal inhlanganisela ye-gasket okanye i-gasket yensimbi;Xa iqondo lokushisa kunye noxinzelelo luzinzile, i-elastic okanye i-self-tightening gasket ikhethiwe;Ubukho bee-gaskets ezisebenza ngokukodwa kufuneka ziqwalaselwe phambi kobushushu obuphantsi, i-media eyonakeleyo okanye i-vacuum.
2. Isicelo sevalve yesango elithambileyo ayisosihlandlo esiphakamileyo, sinokukhethwa ngesifundo, asifanelekanga ukutshintshwa.
3. ngenxa yezo zicelo zezihlandlo ezingqongqo, ezifana negesi eqhumayo, enetyhefu kakhulu kunye negesi enokutsha kunye norhwaphilizo olunamandla lwezixhobo zolwelo, itanki yokusabela ngenkqubo yombhobho, njl. njl., kufuneka isekelwe kuxinzelelo lokusebenza, ubushushu bokusebenza, ukonakala kokutywinwa. medium kunye nokudibanisa ukutywinwa kwemeko yendawo yokukhetha, i-silica gel yokutywina indandatho inesakhiwo esivulekileyo se-porous, sinokufunxa izinto ezininzi, i-desiccant enhle, i-Adsorbent kunye nenkxaso ye-catalyst.I-adsorption ye-silica gel ikakhulu i-adsorption yomzimba, inokuvuselelwa kwaye isetyenziswe ngokuphindaphindiweyo.Yongeza i-asidi kwi-alkali silicate (efana ne-sodium silicate) isisombululo, i-acidize, uze udibanise umlinganiselo othile we-electrolyte ukuze uvuselele, oko kukuthi, ukuvelisa ijeli ye-silicate, okanye ukongeza i-asidi okanye ityuwa ye-ammonium kwisisombululo esigxininisiweyo se-sodium silicate inokuvelisa. ijeli ye-silicate.Iimveliso zejeli yesilika enejeli yesilica njengeyona nto iphambili yokusetyenzwa kwezixhobo, zaziwa njengeemveliso zejeli yesilica, ijeli yesilica yenziwe ngejeli yesilica ngokufanelekileyo ukuphelelwa ngamanzi emzimbeni wezinto ezinobungakanani bamasuntswana ahlukeneyo, inobume obuvulekileyo obuvulekileyo, inokufunxa izinto ezininzi, i-desiccant enhle, i-adsorbent kunye ne-catalyst carrier.
Ivalve yesango yokutywina ethambileyo enoxinzelelo lokutshintsha i-O-ring:
I-1, Ukuba yi-gasket yokutywina ephakathi, umntu kufuneka athobe uxinzelelo kuqala, kwaye i-rubber ye-O-ring yokulungisa ikhithi inokutshintshwa ngokususa isivalo sevalve (njenge-gasket yokutywina, kunokwenzeka ukulungisa i-intanethi ngoxinzelelo. )
2, ukuba i-valve stem ikhonkco lokutywina, kuyimfuneko ukuvula ivalve kwindawo epheleleyo evulekileyo, ukuze itywina elibuyela umva liqinisekise ukuba i-medium ayiyi kuvuza, kwaye emva koko ithathe indawo ye-valve stem seal ring, isango elithambileyo lokutywina. uxinzelelo lwevalvu ngabanye kwi-1.6MPa-.Iimveliso zejeli yesilika enejeli yesilica njengeyona nto iphambili yokusetyenzwa kwezixhobo, zaziwa njengeemveliso zejeli yesilica, ijeli yesilica yenziwe ngejeli yesilica ngokufanelekileyo ukuphelelwa ngamanzi emzimbeni wezinto ezinobungakanani bamasuntswana ahlukeneyo, inobume obuvulekileyo obuvulekileyo, inokufunxa izinto ezininzi, i-desiccant enhle, i-adsorbent kunye ne-catalyst carrier.
3, Ukuba sisitulo sokutywina esithambileyo, isivalo kufuneka sisuswe ngaphambi kokuba sitshintshwe.
