Wax ka baro noocyada kala duwan ee valves ee loo isticmaalo warshadaha saliidda iyo gaaska iyo kala duwanaanshahooda: API iyo ASME iridda, globe, jeeg, kubbadda, iyo naqshadaha balanbaalista (Manual ama actuated, oo leh jir been abuur ah oo la tuuray). Si kooban ayaa loo sheegay, valves waa aaladaha farsamada ee loo isticmaalo codsiyada tuubooyinka si loo xakameeyo, loo xakameeyo oo loo furo/ xiro socodka dareeraha iyo cadaadiska. Tuubooyinka been abuurka ah ayaa loo isticmaalaa codsiyada tuubooyinka cadaadiska sare leh, tuubooyinka tuubooyinka ee ka sarreeya 2 inji.
WAA MAXAY valve?
Noocyada kala duwan ee valves ee loo isticmaalo warshadaha petrochemical waxay ku habboon yihiin mid ka mid ah codsiyada soo socda:
1. Bilow/jooji qulqulka dareeraha (hydrocarbons, oil & gas, steam, water, acids) dhex mara dhuumaha (tusaale: gate valve, valve valve, valvely valve, valve gate valve, ama plug valve)
2. Habee qulqulka dareeraha dhex mara dhuumaha (tusaale: globe valve)
3. Xakamee socodka dareeraha (xakamaynta valve)
4. Beddel jihada qulqulka (tusaale 3-jidka kubbadda)
5. Habbee cadaadiska hab-socodka (cadaadiska yaraynta valve)
6. Ka ilaali nidaamka tuubooyinka ama aaladda (pump, motor, taangi) cadaadiska xad dhaafka ah (badbaadada ama cadaadiska) ama cadaadiska dhabarka (hubi waalka)
7. Kala saar qashinka dhex qulqulaya dhuumaha, si aad u ilaaliso qalabka ay waxyeelayn karaan qaybo adag (y iyo miirayaasha dambiisha)
Waalka waxaa lagu soo saaraa iyadoo la isu keenayo qaybo badan oo makaanik ah, kuwa furaha u ah waa jirka (qolka dibadda), gooynta (isku darka qaybaha qoyan ee la bedeli karo), jirridda, bonetka, iyo habka wax qabad (kabadhka gacanta, qalabka ama actuator).
Valves leh cabbirro yar yar (guud ahaan 2 inji) ama u baahan iska caabin sare oo cadaadiska iyo heerkulka waxaa lagu soo saaraa bir been abuur ah; valves-ganacsiyeedka ka sarreeya 2 inji dhexroorka ah waxay ka kooban yihiin alaabta jirka ee la tuuray.
VALVE BY nashqadaynta
● GATE VALVE: Noocani waa kan ugu badan ee loo isticmaalo tuubooyinka iyo tuubooyinka. Albaabka albaabku waa aaladaha dhaq-dhaqaaqa toosan ee la isticmaalo si furan oo xidha socodka dareeraha Gate valves looma isticmaali karo codsiyada xoqista, ie si loo habeeyo socodka dareeraha (globe ama valves balls waa in la isticmaalo kiiskan). Albaabka albaabka si buuxda ayaa loo furay ama u xidhan yahay (iyada oo la isticmaalayo taayirrada gacanta, gears ama koronto, sambabada hawada iyo hawo-qaadayaasha)
● GLOBE VALVE: Noocan waalka ah waxaa loo isticmaalaa in lagu xakameeyo socodka dareeraha. Gawaarida Globe waxay sidoo kale xiri kartaa socodka, laakiin shaqadan, valves-ka albaabka ayaa la door bidaa. Waalka globe wuxuu abuuraa hoos u dhac cadaadis ah oo ku yimaada dhuumaha, maadaama dareeruhu ay tahay inuu maro marin aan toos ahayn.
● Hubi VALVE: nooca waalka ah waxaa loo isticmaalaa si looga fogaado dib u socodka nidaamka tuubooyinka ama dhuumaha waxyeelayn kara qalabka hoose sida bambooyin, kombaresarada, iwm. Marka dareeruhu leeyahay cadaadis ku filan, wuxuu furayaa valve; marka ay soo noqoto (dib u socodka) cadaadiska naqshadeynta, waxay xireysaa valve - ka hortagga socodka aan loo baahnayn.
● VALVE KUBADDA: Waalka kubbadu waa waalka rubuc-wareega ee loo isticmaalo codsiga xidhitaanka. Waalka waxa uu furaa oo xidhaa socodka dareeraha isaga oo sii maraya kubbad ku dhex jirta, taas oo ku dhex wareegta jidhka waalka. Baallooyinka kubbaddu waa halbeegga warshadaha ee codsiyada dibadda ah waxayna ka fudud yihiin oo ka cufan yihiin valves-ka albaabka, kuwaas oo u adeega ujeeddooyin isku mid ah. Labada naqshadood ee ugu waaweyn waa sabbaynaya iyo trunnion (dhinac ama gelitaanka sare)
● BUTTERFLY VALVE: Kani waa faa'iido badan, kharash-ku-ool ah, valve si loo beddelo ama loo furo/ xiro qulqulka dareeraha. Valfyada Balanbaalista waxay ku diyaarsan yihiin qaab-dhismeed kooban ama qaab-dhismeed (double/saddex), waxay leeyihiin qaab is haysta waxayna noqonayaan kuwo aad iyo aad u tartan badan
● PINCH VALVE: Kani waa nooc ka mid ah waalka dhaqaaqa toosan oo loo isticmaali karo ceejinta iyo daminta codsiga tuubooyinka ee qaada walxaha adag, dareeraha iyo dareeraha cufan. Waalka qanjaruufo wuxuu leeyahay tuubo qanjaruufo ah si loo habeeyo socodka.
PLUG VALVE: Plug valve waxa loo kala saaraa sidii waalka rubuc-wareega ee codsiyada xidhidhka. Tuubooyinkii ugu horreeyay waxaa keenay Roomaaniyiintu si ay u xakameeyaan dhuumaha biyaha.
● SAFETY VALVE: Aaladda badbaadada waxaa loo isticmaalaa in laga ilaaliyo habaynta tuubooyinka cadaadiska xad dhaafka ah ee khatarta gelin kara nolosha aadanaha ama hantida kale. Asal ahaan, waalka badbaadada ayaa sii daaya cadaadiska marka qiimaha go'an la dhaafo.
● Kontaroolka valve: kuwani waa mashiinnada si otomaatig ah loogu sameeyo hababka batroolka ee adag.
● Y-STRAINERS: iyadoo aan si sax ah loo isticmaalin, Y-strainers waxay leeyihiin shaqada muhiimka ah ee shaandhaynta qashinka iyo ilaalinta qalabka hoose ee laga yaabo inay si kale u dhaawacmaan.
