Mulimo wakubelesya vvalavu yakukwabilila nkulesya kweenda kwamukati, mpawo vvalavu yakukwabilila kanjikanji ilabikkwa aawo pompi mpoizwa. Mukuyungizya, vvalavu yakukwabilila yeelede kubikwa aawo mpoizwa kkompyuta. Mubufwiifwi, kuchitila kutabilila kujokela musule kwachiimo, chikwabilizyo cheelede kubikwa azibelesyo, chibelesyo naakuti payipi.
Kanjaanji, mavwili aakulanga zintu ziimvwi nji abelesyegwa kumapayipi aali mumbali aajisi bupati bwa 50mm. Ivalvu yakulanga zintu iiluleme ilakonzya kubikwa kumapayipi aali mujulu aali atala. Ivalvu yamunsi kanjikanji ibikkwa buyo aamupayipi uuimvwi wa pompi, mpawo akati-kati ulazwa ansi kuya atala.
Ivalvu yakuzungaana ilakonzya kuchitwa kuti ibe anguzu zyakubeleka zisumpukide, PN ilakonzya kusika ku 42MPa, mpawo DN ilakonzya kuchitwa kuti ibe mpati loko, mpati ilakonzya kusika kwiinda 2000mm. Kweelana azintu zisiyene-siyene zyachikwabilizyo achisinkilizyo, zilakonzya kubelesegwa kulizyoonse zibelesegwa akupya kuli koonse. Inzila eeyi njakuti maanzi, busi, igesi, nzila iikola, mafuta, chakulya, misamu, azimwi. Ikupya kwakubelesya ooku kuli akati ka -196~800°C.
Busena bwakubikkwa kwa swing check valve tabukwe mpindu pe, kanjikanji bubikkwa aamupayipi uulangene, asi bulakonzya kubikkwa amupayipi uuimvwi nji naakuti uulangene.
Chiindi chikonzya kubelesegwa cha butterfly check valve nchakutontola aansi mpawo chilamfu, mpawo chiindi chakubikka nchiche. Nkaambo kakuti nguzu zyakubeleka zya butterfly check valve tazikonzyi kuba atala loko, pesi bupati bulakonzya kusika ku 2000mm, pesi nguzu zili munsi aa 6.4MPa. Ivalvu ya butterfly check ilakonzya kuchitwa kuba musyobo wa wafer, eeyo kanjikanji iibikkwa aakati kama flange obile aamupayipi munzila ya wafer connection.
Busena bwakubikkwa kwa butterfly check valve tabukwe mpindu pe, bulakonzya kubikkwa aamupaipi uulangene, mupaipi uuimvwi nji naa mupaipi uulangene.
Ivalavu yakulanga-langa diaphragm ileelela kumapaipi aakonzya kunyonyooka amaanzi. I diaphragm ilakonzya kugwisya nkomo yamaanzi iiletwa akujokela musyule kwachintu chili akati. Mbwaanga kupya kwakubeleka akusinikizyigwa kwakubelesya mavalvu aa diaphragm zilalesyegwa azintu zya diaphragm, kanjikanji zibelesyegwa mumapaipi aajisi muya musyoonto alimwi aajisi kupya kubotu, ikapati kumapaipi aameenda aamupompi. Kanjaanji, kupya kwakubeleka kwachintu chili akati ka -20~120°C, mpawo kupya kwakubeleka kuli munsi aa 1.6MPa, asi vvalavu ya diaphragm ilakonzya kusika abwamba bupati, mpawo DN mpati ilakonzya kwiinda 2000mm.
Diaphragm check valve yakabelesegwa loko muminyaka misyoonto yainda akaambo kakubeleka kabotu kwayo kutanjili maanzi, bupange buuba-uba alimwi amali masyoonto aakupanga.
Ibbola lyakulanga bbola lilijisi mulimo mubotu wakujala, kubeleka kabotu alimwi akukazya nkomo yamaanzi nkaambo chijazyo nchintu chivwumbidwe a raba; alimwi nkaambo kakuti chisinkilizyo chilakonzya kuba bbola lyomwe naakuti mabbola miingi, chilakonzya kuchitwa kuba abwaamba bupati. Nokuba boobo, chisinkilizyo chacho nchintu chivwumbidwe a raba, eecho chiteelede kubelesegwa mumapayipi aamanguzu manji, pesi ayelede buyo kumapaipi aajisi manguzu aakati aakati-akati aansi.
Mbwaanga chikumba cha ball check valve chilakonzya kuchitwa abutale butakwe tombe, mpawo bbola lyachikwabilizyo lilakonzya kuvwumbwa apulasitiki ya PTFE, lilakonzya kubelesegwa mumapayipi ajisi zintu zikonzya kubola.
Ikupya kwakubeleka kwamusyobo ooyu wakukwabilila kuli akati ka -101~150°C, muya uuzyibidwe uli ≤4.0MPa, mpawo bupati buli akati ka 200~1200mm.
