I-valve yokumisa iyi-valve yebhulokhi, edlala indima enkulu ekunqumeni ipayipi.
Iivalvu yomhlabaiyivalvu esetshenziswa kakhulu, futhi futhi iyindlela efaneleka kakhulu yokugoqa. Ngenxa yokuthi isebenza kahle ekulungiseni, futhi uma iqhathaniswa nezinye izinhlobo zamavalvu esakhiwo, ukusatshalaliswa kokuguguleka okuzungeze isihlalo sevalvu yokuma ngenxa yokuguguleka kuyafana kakhulu.
I-globe valve iyi-valve ephoqelelwa ukuvala. Ngakho-ke, indlela yokukhetha kahle i-globe valve kumele ifake ingcindezi ku-wide flap lapho ivaliwe, ukuze kungabikho ukuvuza okwenzekayo phakathi kwezindawo ezimbili zokuvala. Njengoba amandla okuvala e-globe valve kanye nengcindezi ephakathi ku-axis efanayo, futhi iziqondiso ziphambene, amandla okuvala awagcini nje ngokukhuliswa, kodwa futhi anqoba ingcindezi ye-medium, ngakho-ke amandla okuvala adingwa yi-globe valve valve makhulu kakhulu kunalawo e-gate valve.
Kufanele kuqashelwe ngokukhethekile ukukhethwa kwevalvu yomhlaba. Ivalvu yomhlaba enendandatho yokuvala eyisicaba ayikwazi ukusetshenziselwa imidiya engcolile noma imidiya equkethe izinhlayiya eziqinile. Kulesi sikhungo, kungcono ukusebenzisa indawo yokuvala enciphile ukuze kuvalwe.
Ngokuvamile, ama-valve okusika anconywa ngezinhlelo zamapayipi okucindezela, ukuqondisa, kanye nokucindezela okuphezulu; ama-valve okusika angakhethwa ukuze kulungiswe izindawo ezimbili, izidingo zesakhiwo ezilula nezincane, azikho izidingo eziqinile ngobude besakhiwo, ukucindezela okuphansi (umehluko omncane wengcindezi), kanye nemidiya yokushisa okuphezulu. ; Odakeni, i-medium equkethe izinhlayiya zomzimba ofanayo, ukumelana nokuguguleka, ukuncipha kobubanzi, isenzo esisheshayo (ukujika okuningi noma ukuvula nokuvala), kanye namandla aphansi okusebenza, zama ukungakhethi i-valve yokuma; uma idinga ukusebenza kahle kokuvala, ukucindezela okuphakeme (umehluko omkhulu wengcindezi)), umsindo ophansi, ukugoba kanye nokuhwamuka, inani elincane lokuvuza emoyeni, imidiya ehlukumezayo, izinga lokushisa eliphansi kanye nokubanda okujulile, ungasebenzisa isakhiwo esikhethekile somklamo we-valve yomhlaba.
Esinye isici esibalulekile se-globe valve ukuthi uphawu lwesiqu se-valve lungathathelwa indawo yi-bellows esikhundleni sokupakisha ukuze kwakheke i-bellows globe valve. I-bellows globe valve ifanelekela imidiya evuthayo, eqhumayo, enobuthi, nehlanzekile, futhi ingahlangabezana nezidingo zesistimu ye-vacuum.
Kodwa-ke, i-globe valve nayo inezinkinga zayo, ikakhulukazi ezibangelwa ukuma kwangaphakathi komzimba we-valve. Emgodini womzimba we-globe valve, i-medium iyashintsha kusuka ekugelezeni okuqondile okuvundlile kuya ekugelezeni okuqondile okuphezulu noma okuphansi, bese kuba ukugeleza okuvundlile, okuholela ekulahlekelweni kwengcindezi, ikakhulukazi kumadivayisi e-hydraulic. Lolu hlobo lokulahlekelwa kwengcindezi kufanele ludonse ukunaka okwanele.
