Yintoni eqinisekisa ukusebenza ngokutywina kweevali zokujonga?

Zeziphi iimfihlo ezingaziwayo kwintsebenzo yokutywinaJonga i-valveves? Kwinethiwekhi ye-Arterial "yoThutho lwemizi-mveliso, i-valves injenge-vabhu" abagcini-masango ", bavimba ngokuqinileyo i-medium efuna ukubaleka umva - kodwa ubusazi? Ukuzithemba kwayo okungagungqi akukaze kuphume umoya omncinci.

Okokuqala, masithethe malunga nentsebenziswano 'ye-Tacit Chantity': i-disc disve kunye nesihlalo sevalve. Ukuba ezi zinto zimbini azingqinelani kakuhle, nokuba yeyona valve inamandla yokujonga iya kuba lilize. Ndizibonile iivalva ezimgangatho ophezulu, kwaye ndikwinqanaba loyilo, bendikhuphisana ngeli "iqabane", iPoliling onke amanyathelo ale nkqubo. Indawo yokugqibela yoqhakamshelwano igudileyo kangangokuba inokubonisa inani, kwaye iflethi ichanekile kwinqanaba le-micrometer. Nje ukuba ivalve ivaliwe, i-valve idiski ibonakala ikhula kwisitulo sevalve, ngokufanelekileyo kwaye ayikwazi nokuphefumla. Okokugqibela ndijonga kumbhobho wokuthulula i-hydrochloric acid kwisityalo sekhemikhali, bendithembele kweli "liqabane" ukumelana nolusu. Ukuba ivuza, iziphumo ziya kubangenasiphelo.

Makhe sithethe ngentwasahlobo efihliweyo ngaphakathi. Musa ukukhohliswa kukutyeba kwayo, eneneni 'ithambo elinzima' kumaxesha anzima. Xa ihambahamba iphakathi, iyaphumla kwaye inceda i-valve ivuliwe ngokulula; Nje ukuba iphakathi yayisele ibuye umva, kwaoko kwakhanyisa kwaye "yenqwanqwa" ibhotile yebhotile ibuyela kwisitulo sevali, kwaye iziphumo zokutywina ziphuculwe kwangoko. Masithethe malunga nempompo yokubonelela ngamanzi eluntwini. Iqhelekile into yokuba ingcinezelo yamanzi ukuze iguquke. Enkosi kumandla obukrelekrele bomthombo,Jonga i-valveUnokuzinzisa imeko kwaye uthintele amanzi ukuba ahambe kwaye ayonakalise impompo.

Kukwakho nokukhetha izinto zokutywina, ezisisisa ngobuchule "bebukele iphakathi ngaphambi kokupheka". Ubushushu bendawo yahlukile, kwaye izinto ezibonakalayo kufuneka zitshintshe ngokufanelekileyo. I-valve ehambisa i-steam kufuneka isebenzise izixhobo ezinokumelana namakhulu amancinci amaqondo obushushu, kungenjalo iya kuba utyalo kwaye itywina liya kuba yintetho engenanto; Ukuba udibana ne-acidic eyomeleleyo kunye ne-alkaline "enesidima" esiphakathi, kufuneka uyitshintshe ngentonga yokunganyangeki, kungenjalo ngaphambi kokuba ilindelwe kwaye ikhutshiwe ngemingxunya. Ndaya kumzi-mveliso wasemachiza kwithuba elidlulileyo, kwaye basebenzisa ivalve yokujonga yokuhambisa utywala, obutywiniweyo ngegarakethi ye-orgation. Emva kweminyaka engaphezu kwemibini yokusetyenziswa, isabonakala ngathi intsha.

Ekugqibeleni, ukusebenza kokutywina kweJonga i-valveAKUFUNI KUPHI IQINISEKILEYO ESINYE isebenza yedwa. Kukulingana okuqinileyo phakathi kwe-disve ye-valve kunye nesitulo sehafu, ukuqina kwentwasahlobo, kunye nempahla efanelekileyo yokutywina enokuthi sonke senze lo "xinzelelo", kunye noxinzelelo oluphezulu.
