Gate valve waxaa si weyn loogu isticmaalaa qalabka lagu gooyo dhexroorka DN ≥ 50mm, marmarka qaarkood albaabbada albaabka ayaa sidoo kale loo isticmaalaa in lagu gooyo qalabka leh dhexroor yar.
Qaybta furitaanka iyo xidhitaanka ee waalka iridu waa albaabka, jihada dhaqdhaqaaqa albaabkuna waa mid siman jihada dareeraha.Albaabka albaabka waxa kaliya oo si buuxda loo furi karaa oo si buuxda ayaa loo xidhi karaa, lamana hagaajin karo lamana riixi karo.Albaabka waxa uu leeyahay laba dusha oo daboolaya.Labada sagxood ee daboolka ah ee sida caadiga ah loo isticmaalo waalka albaabka hannaanka waxay sameeyaan qaab jeex ah.Xagasha jeexdu waxay ku kala duwan tahay cabbirada waalka, badiyaa 50, iyo 2°52' marka heerkulka dhexdhexaadku aanu sarreyn.Albaabka albaabka jeexjeexa waxaa laga samayn karaa gebi ahaan, kaas oo loo yaqaan albaab adag;waxa kale oo laga dhigi karaa albaab soo saari kara qadar yar oo qallafsan si loo hagaajiyo wax soo saarkeeda iyo magdhowga leexinta xagasha dusha daboolida inta lagu jiro farsamaynta.Saxanka waxaa lagu magacaabaa albaabka laastikada.Gate valve waa qalabka ugu muhiimsan ee lagu koontaroolo socodka ama gudbinta mugga budada, alaabta badarka, walxo granular iyo walxo yar yar.Waxaa si weyn loogu isticmaalaa biraha, macdanta, qalabka dhismaha, hadhuudhka, warshadaha kiimikada iyo warshadaha kale si loo xakameeyo socodka isbeddelka ama si degdeg ah loo gooyo.
Gate valves waxay si gaar ah u tixraacaan noocyada kabka albaabka birta, kuwaas oo loo qaybin karo valves gate wedge, valves gate barbaro ah, iyo alxanka iridda valves iyadoo loo eegayo qaabeynta ee dusha shaabadeynta.Albaabka albaabka waxaa loo qaybin karaa: nooca iridda kaliya, nooca iridda labalaabka ah iyo nooca iridda laastikada;bar-bar-bar-bareedka gate-ga waxa loo qaybin karaa nooc hal-albaab ah iyo nooca iridda laba-laaban ah.Marka loo eego booska dunta ee jirridda, waxa loo qaybin karaa laba nooc: kor u kaca waalka albaabka asliga iyo waalka albaabka asliga ee aan kor u kicin.
Marka albaabka albaabka la xiro, dusha daboolka waxaa lagu xiri karaa oo kaliya cadaadiska dhexdhexaadka ah, taas oo ah, ku tiirsanaanta cadaadiska dhexdhexaadka ah si aad u riixdo dusha daboolka ee saxanka albaabka kursiga valve ee dhinaca kale si loo hubiyo xiritaanka dusha daboolida, taas oo ah is-xakamaynta.Inta badan albaabka albaabka waa shaabad qasab ah, taas oo ah in la yiraahdo, marka waalka la xiro, albaabka waa in lagu cadaadiyaa kursiga waalka ee xoogga dibadda, si loo hubiyo xiritaanka dusha sare ee daboolka.
Albaabka waalka gate wuxuu u socdaa xariiq toosan oo leh jirida waalka, kaas oo loo yaqaan waalka gate gate ee kor u qaadaya (sidoo kale loo yaqaan kor u kaca stem gate valve).Caadi ahaan waxaa jira dunta trapezoidal on wiishka, iyo iyada oo loo marayo lowska sare ee waalka iyo jeexdin hagaha ee jirka waalka, dhaqdhaqaaqa wareega ayaa loo beddelaa dhaqdhaqaaq toosan, taas oo ah in la yiraahdo, qulqulka hawlgalka waa la beddelaa. galay riixitaanka hawlgalka.
Marka waalka la furo, marka dhererka wiishka ee saxanka albaabka uu le'eg yahay 1: 1 dhexroorka tuubada, marinka dareeraha ayaa gebi ahaanba xiran, laakiin booskan lama kormeeri karo inta lagu jiro hawlgalka.Isticmaalka dhabta ah, meesha ugu sarreysa ee jirridda waalka waxaa loo isticmaalaa calaamad ahaan, taas oo ah, booska meesha uu jirku uusan dhaqaaqin waxaa loo qaataa booska si buuxda u furan.Si loo tixgeliyo ifafaale qufulka sababtoo ah isbeddelada heerkulka, badiyaa u fur booska ugu sarreeya, ka dibna dib u rog 1/2-1, sida booska si buuxda u furan.Sidaa darteed, booska si buuxda u furan ee waalka waxaa lagu go'aamiyaa booska albaabka (taas oo ah, istaroogga).
Albaabka albaabka qaar ka mid ah, lawska asliga ah ayaa lagu dhejiyaa saxanka albaabka, wareegtada taayirrada gacantuna waxay waddaa jirida valve si uu u wareego, saxanka albaabka ayaa kor loo qaadayaa.Waalka noocaan ah waxaa loo yaqaan waalka iridda asliga ah ee rotary ama galka albaabka asliga ee mugdiga ah.
