Ngokuthuthuka okuqhubekayo kwe-automation yezimboni, ukusetshenziswa kwei-valve ye-pneumatic cut-off luyanda futhi lubanzi. Ezindaweni eziningi zezimboni, ama-valve anqamule umoya womoya adlala indima ebalulekile, njenge-petroleum, amakhemikhali, i-metallurgy, izinto zokwakha nokunye. Namuhla, sizobheka kabanzi ngesakhiwo kanye nesimiso sokusebenza se-valve yokusika umoya ukuze siqonde kangcono futhi sisebenzise le mishini ebalulekile.
Okokuqala, isakhiwo esiyisisekelo se-valve ye-pneumatic cut-off
I-valve yokusika umoya we-pneumatic ikakhulukazi yakhiwe izingxenye ezilandelayo: umzimba we-valve, ikhava ye-valve, i-valve core, umshayeli, indandatho yokuvala kanye nezingxenye zokuxhuma. Umzimba we-valve kanye nesembozo se-valve inikeza ukusekelwa kwesakhiwo se-valve yokusika umoya; I-spool iyingxenye eyinhloko ye-valve yokusika umoya, enesibopho sokulawula ukugeleza kwe-medium; Umshayeli unesibopho sokuguqula isignali yomthombo womoya ibe ukunyakaza komshini, ukushayela umgogodla wevalvu ukuze ibone iswishi; Indandatho yokuvala iqinisekisa ukusebenza kokuvala kwe-valve; Isixhumi sixhuma i-valve yokusika umoya ohlelweni lwamapayipi.
Okwesibili, isimiso sokusebenza se-valve yokusika umoya womoya
Umgomo wokusebenza we-valve yokusika umoya ungafingqwa njengezinyathelo ezilandelayo:
1. Uma i-valve yokusika umoya idinga ukuvalwa, isistimu yomthombo womoya inikeza isignali yomoya ocindezelwe kumshayeli. Umoya ocindezelwe ungena ngokungenisa umoya wedrayivu, uphushela amapiston okushayela ngaphandle.
2. Uma ipiston yomshayeli ihambela ngaphandle, phakamisa i-spool uye phezulu ngokusebenzisa intonga yokuxhuma. Igebe phakathi kwe-spool nesihlalo liba likhulu, futhi i-medium ayikwazi ukugeleza, ukuze kuzuzwe inhloso yokusika.
3. Uma ivalvu yokunqamula umoya idinga ukuvulwa, uhlelo lomthombo womoya luyayeka ukuhlinzeka ngegesi. Intwasahlobo yomshayeli ibuyela emuva futhi icindezela i-spool phansi ukuze i-spool ingene ngokuqinile esihlalweni. Ngalesi sikhathi, okuphakathi kungadlula kahle ku-valve yokusika umoya.
4. Ukuze kuqinisekiswe ukusebenza kokuvala kwe-valve yokusika umoya, indandatho yokuvala ihlelwa phakathi kwe-spool nesihlalo. Endabeni yokulingana okuqinile phakathi kwe-spool nesihlalo, indandatho yokuvala ingavimbela ngempumelelo ukuvuza kwemidiya.
Kafushane, ukwakheka kanye nesimiso sokusebenza se-valve yokusika umoya ilula, kodwa indima yayo emkhakheni we-automation yezimboni ibalulekile. Ukuqonda isakhiwo kanye nesimiso sokusebenza se-valve yokuvala umoya we-pneumatic kusisiza ukuba sisebenzise kangcono lesi sisetshenziswa futhi sithuthukise ukusebenza kahle kokukhiqiza nokuphepha.
