Umgaqo wokusebenza weglobeivalvu:

Amanzi afakwa ezantsi kombhobho aze akhutshwe aye emlonyeni wombhobho, ukuba kukho umgca wokuhambisa amanzi onesiciko. Isigqubuthelo sombhobho wokuphuma sisebenza njengendlela yokuvala ivalvu yokumisa. Amanzi aza kukhutshwa ngaphandle ukuba isigqubuthelo sombhobho siphakanyisiwe ngesandla. Amanzi aya kuyeka ukudada ukuba isigqubuthelo sombhobho sigqunywe ngesandla sakho, into efana nomsebenzi wevalvu yokumisa.

Iimpawu zevalvu yeglobhu:

Xa ifakelwe, ingena kancinci kwaye iphuma kancinci, ukuhamba kwecala, ukumelana nokungqubana kwamanzi okukhulu, imveliso nokugcinwa okulula, ulwakhiwo olulula, ukuchaneka okuphezulu; isetyenziswa ngokukodwa kumanzi ashushu nabandayo kunye nemibhobho yomphunga enoxinzelelo oluphezulu; ayisebenzi Izinyibilikisi ezine-particle matter kunye ne-viscosity ephezulu.

Umgaqo wokusebenza kwevalvu yebhola:

Umphezulu ongqukuva kwindawo yokungena kunye neyokuphuma kufuneka ubonakale ngokupheleleyo xa ivalvu yebhola ijikeleze ii-degrees ezingama-90. Ngelo xesha, ivalvu ivaliwe ukuze kuthintelwe isinyibilikisi ekuqubheni. Kufuneka kubekho iindawo ezivulekileyo zebhola emnyango nakwindawo edibana kuyo xa ivalvu yebhola ijikeleza ii-degrees ezingama-90, kwaye emva koko kufuneka zivuleke kwaye ziqubhe ukuze kungabikho kuxhathisa ukuhamba kwamanzi.
Iimpawu zeevalvu zebhola:

Iivalvu yebholaKulula ukuyisebenzisa, iyakhawuleza, kwaye iyonga abasebenzi. Ivalvu yebhola ingasetyenziswa nolwelo olungangcolanga kakhulu (oluqulethe amasuntswana aqinileyo) ngokujika nje isiphatho sevalvu ngama-90 degrees. Oku kungenxa yokuba ulwelo luchaphazeleka yi-spiral core yevalvu xa ivulwa kwaye ivalwa. Yintshukumo yokusika.

Umgaqo wokusebenza wevalvu yesango:

Uhlobo oluqhelekileyo lwevalvu yivalvu yesango, ngamanye amaxesha eyaziwa ngokuba yivalvu yesango. Umgaqo wayo wokusebenza wokuvala nokuvala kukuba iindawo zokutywina zepleyiti yesango kunye nesihlalo sevalvu, ezihambelana kunye ukuvimba ukuhamba kolwelo oluphakathi kunye nokuphucula ukusebenza kokutywina kusetyenziswa intwasahlobo okanye imodeli ebonakalayo yepleyiti yesango, zigudile kakhulu kwaye zihambelana. Umsebenzi oyintloko wevalvu yesango kukuyeka ukudlula kolwelo kumbhobho.

Iimpawu zevalvu yesango:

Ukusebenza kokutywina kungaphezulu kune-valve yeglobe, ukumelana nokungqubana kolwelo kuphantsi, ukuvulwa nokuvalwa kufuna umsebenzi omninzi, umphezulu wokutywina awonakaliswa kakhulu yi-solvent xa ivuliwe ngokupheleleyo, kwaye ukusebenza kokutywina akuthintelwa yindlela izinto ezihamba ngayo. Ixesha lokuvula nokuvala lide, ubungakanani bukhulu, kwaye kufuneka indawo ethile. Xa kuvulwa nakuvalwa, umphezulu wokutywina uyaguguleka kwaye unqunyulwe lula. Ezi zimbini zokutywina zizisa imingeni yokucubungula, ukugcinwa, kunye nemveliso.

Isishwankathelo somahluko phakathi kweevalvu zeglobe,iivalvu zebholakunye neevalvu zesango:

Nangona iivalvu zeglobe zingasetyenziselwa zombini ulawulo lokuhamba kwamanzi kunye neswitshi yokulawula ulwelo kunye nokunqunyulwa, iivalvu zebhola kunye neevalvu zesango zihlala zisetyenziselwa iswitshi yokulawula ulwelo kunye nokunqunyulwa kwaye azifane zisetyenziswe kwimithetho yokuqukuqela kokuhamba kwamanzi. Kungcono ukusebenzisa ivalvu yokumisa emva kwemitha xa kufuneka utshintshe izinga lokuhamba kwamanzi. Iivalvu zesango zisetyenziswa kwiswitshi yokulawula kunye nezicelo zokunqunyulwa kokuhamba kwamanzi kuba zisebenza kakuhle ngokwezoqoqosho. Okanye, kwimibhobho yeoyile, umphunga, kunye namanzi enobubanzi obukhulu, enoxinzelelo oluphantsi, sebenzisa iivalvu zesango. Ukuqina kufuna ukusetyenziswa kweevalvu zebhola. Iivalvu zebhola zingcono kuneevalvu zesango ngokwendlela yokusebenza yokhuseleko kunye nobomi, kwaye zingasetyenziswa kwiindawo ezinemigangatho engqongqo yokuvuza. Zikwafanelekile ukuvulwa nokuvalwa ngokukhawuleza.
