Umgaqo wokusebenza weglowubhuivalve:

Amanzi atofwa ukusuka ngaphantsi kombhobho aze akhululwe ukuya emlonyeni wombhobho, ecinga ukuba kukho umgca wokuhambisa amanzi kunye ne-cap. Isigqubuthelo sombhobho ophumayo sisebenza njengesixhobo sokuvala sesivalo. Amanzi aya kukhutshwa ngaphandle ukuba umnqwazi wombhobho uphakanyiswa ngesandla. Amanzi aya kuyeka ukuqubha ukuba umnqwazi wombhobho wogqunywe ngesandla sakho, nto leyo efana nomsebenzi wevalve yokumisa.

Iimpawu zevalve yeglowubhu:

Xa ifakwe, iphantsi kwaye iphezulu, ukuhamba kwesikhokelo, ukuxhathisa okukhulu kokuxhatshazwa kwamanzi, imveliso efanelekileyo kunye nokugcinwa, isakhiwo esilula, ukuchaneka okuphezulu; isetyenziswe ngokukodwa kunikezelo lwamanzi ashushu nabandayo kunye nemibhobho yomphunga woxinzelelo oluphezulu; ayisebenzi Izinyibilikisi ezine-particle kunye ne-viscosity ephezulu.

Umgaqo wokusebenza kwevalvu yebhola:

Umphezulu we-spherical kwindawo yokungena kunye nokuphuma kufuneka ubonakale ngokupheleleyo xa i-valve yebhola ijikeleze i-90 degrees. Ngelo xesha, ivalve ivaliwe ukumisa i-solvent ekuqubheni. Kufuneka kubekho ukuvuleka kwebhola ekungeneni kunye nokudibanisa xa ivalve yebhola ijikeleza i-90 degrees, kwaye kufuneka ivule kwaye iqubhe ukuze kungabikho ukuxhathisa ukuhamba.
Iimpawu zeevalvu zebhola:

Iivalve yebholakulula ukuyisebenzisa, iyakhawuleza, kwaye igcina umsebenzi. Ivalve yebhola ingasetyenziselwa ulwelo olungacocekanga kakhulu (eliqulathe amasuntswana aqinileyo) ngokujika nje isiphatho sevalvu ngama-90 degrees. Oku kungenxa yokuba ulwelo luchatshazelwa ngumbindi wevalve xa ivulwa kwaye ivaliwe. sisindululo sokusika.

Umgaqo osebenzayo wevalve yesango:

Uhlobo oluqhelekileyo lwevalve yivalve yesango, ngamanye amaxesha eyaziwa ngokuba yivalve yesango. Umgaqo wayo wokuvala nokuvalwa kwawo kukuba imiphezulu yokutywina yepleyiti yesango kunye nesitulo sevalvu, ezidibana kunye ukuvala ukuhamba kolwelo oluphakathi kunye nokuphucula ukusebenza kokutywinwa kusetyenziswa intwasahlobo okanye imodeli ebonakalayo yepleyiti yesango, zigqithise kakhulu. egudileyo kwaye iyahambelana. isiphumo sokwenyani. Umsebenzi ophambili wevalve yesango kukumisa indlela yolwelo ngombhobho.

Iimpawu zevalve yesango:

Ukusebenza kokutywinwa kuphezulu kunoko kwevalve yeglowubhu, ukuxhathisa ukukhuhlana kwamanzi kuphantsi, ukuvula kunye nokuvala kufuna umsebenzi othe kratya, indawo yokutywina ayithotywanga yi-solvent xa ivuleke ngokupheleleyo, kwaye ukusebenza kokutywinwa akuthintelwa ngumkhombandlela wokuhamba kwezinto. Ixesha lokuvula kunye nexesha lokuvala lide, ubukhulu bukhulu, kunye nenani elithile legumbi elifunekayo. Xa uvula kwaye uvala, indawo yokutywina iyancipha ngokulula kwaye inqunywe. Ezi zibini zokutywina zinika imingeni ekusetyenzweni, ekugcinweni nasekuveliseni.

Isishwankathelo somahluko phakathi kweevalvu zeglowubhu,iivalve zebholakunye neevalvu zesango:

Ngelixa iivalvu zeglowubhu zingasetyenziselwa zombini ukulawulwa kokuhamba kunye nokutshintsha kokulawula ulwelo kunye nokunqunyulwa, iivalvu zebhola kunye neevalvu zesango ziqhele ukusetyenziselwa ukutshintshwa kolwelo kunye nokunqunyulwa kwaye kunqabile ukuba kulawuleke ukuhamba. Kungcono ukusebenzisa ivalve yokumisa emva kwemitha xa ufuna ukuguqula izinga lokuhamba. Iivalve zesango zisetyenziselwa ukutshintshwa kokulawula kunye nezicelo ezinqamlekileyo ngenxa yokuba zisebenza ngakumbi ngokwezoqoqosho. Okanye, kwi-diameter enkulu, i-oyile yoxinzelelo oluphantsi, umphunga, kunye nemibhobho yamanzi, sebenzisa iivalvu zesango. Ukuqina kufuna ukusetyenziswa kweevalvu zebhola. Iivalvu zebhola ziphakamile kuneevalvu zesango ngokusebenza kokhuseleko kunye nobude bokuphila, kwaye zingasetyenziswa kwindawo eneenqobo zokuvuza ezingqongqo. Zikwafanelekile ukuvula nokuvala ngokukhawuleza.
