Gawaarida kubbadda caaga ah, Sida qaybaha muhiimka ah ee kantaroolka ee nidaamyada dhuumaha, ayaa si ballaaran loo isticmaalaa meelo kala duwan sida daaweynta biyaha, injineernimada kiimikada, cuntada iyo daawada. Xulashada saxda ah ee moodeelku waxay u baahan tahay in la tixgeliyo arrimo kala duwan sida walxaha, habka isku xirka, qiimeynta cadaadiska, kala duwanaanta heerkulka, iwm. Hagahan ayaa si habaysan u soo bandhigi doona qodobbada muhiimka ah ee xulashadavalves kubbadda caagga ah, kaa caawinaya inaad samayso doorasho macquul ah.
Kala soocida aasaasiga ah iyo jaangooyooyinka balaastikada balaastikada ah
1. Hababka kala soocida ugu weyn
Albaabka kubbadda caaga ah waxaa loo kala saari karaa iyadoo loo eegayo heerar kala duwan:
(a) Habka isku xirka:
Flangebalaastikada kubbadda: ku habboon nidaamyada dhuumaha dhexroorka weyn
Waalka kubbadda balaastiga ah ee dunsan: caadi ahaan loo isticmaalo dhuumaha dhexroorka yar
Socket ball valve ball: fududahay in si degdeg ah loo rakibo
Waalka kubbadda balaastiga ah ee laba-jibbaaran: fududahay in la kala diro oo la dayactiro
(b) Habka wadista:
Waalka kubbadda gacanta: mid dhaqaale iyo mid la taaban karo
Waalka kubbadda pneumatic: kontoroolka otomaatiga ah
Waalka kubbadda korantada: hagaajinta saxda ah
(c) Qoraal ahaan:
UPVC kubad waalka: ku haboon daaweynta biyaha
PP ball valve: Cuntada iyo warshadaha dawooyinka
Waalka kubbadda PVDF: Dhexdhexaad daxal leh oo xooggan
Waalka kubbadda CPVC: deegaan heerkul sarreeya
2. Heerarka iyo tilmaamaha qaranka
Heerarka ugu muhiimsan eevalves kubbadda caagga ahShiinaha waa sida soo socota:
GB/T 18742.2-2002: Qalabka kubbadda caaga ah ee ku habboon DN15 ~ DN400, cadaadiska lagu qiimeeyay PN1.6 ~ PN16
GB.
3. Xulashada agabka lagu xidho
EPDM ternary ethylene propylene caag: aashitada iyo alkali u adkaysta, heerkulka kala duwan -10 ℃ ~ + 60 ℃
FKM fluororubber: dareeraha u adkaysta, heerkulka kala duwan -20 ℃ ~ + 95 ℃
PTFE polytetrafluoroethylene: u adkaysata daxalka adag, heerkulka kala duwan -40 ℃ ilaa +140 ℃
