Intumbero yo gukoresha umupfunda wo gupima ni ugukingira umupfunda wo gusubira inyuma, kandi muri rusangi umupfunda wo gupima ushirwa aho ipompa isohokera. Ikindi, n’aho iyo compresseur isohokera, hakwiye kushirwako n’ivyuma bigenzura amazi. Muri make, kugira ngo umuvuduko w’amazi ntusubire inyuma, hakwiye kushirwako umupfunda wo gusuzuma ku gikoresho, ku gikoresho canke ku muyoboro.
Muri rusangi, amavalve yo gupima uguterura ahagaze akoreshwa ku mirongo y’amazi iringaniye ifise umurongo w’izina wa 50mm. Igikoresho co gupima amazi gishobora gushirwa ku mirongo y’amazi iringaniye n’iyihagaze. Ico gikoresho co hasi muri rusangi gishirwa gusa ku muyoboro uhagaze w’inzira y’ipompa, kandi umuyoboro wo hagati uva hasi uja hejuru.
Swing check valve ishobora gukorwa mu gipimo kinini cane c’akazi, PN ishobora gushika kuri 42MPa, na DN nayo ishobora gukorwa nini cane, igipimo gikomeye gishobora gushika ku 2000mm. Dushingiye ku bikoresho bitandukanye vy’igikoko n’ikidodo, gishobora gukoreshwa ku kintu cose gikoreshwa n’ubushuhe bwose bukoreshwa. Ivyo bikoresho ni amazi, umwotsi, gaze, ivyo bikoresho bitera ubumara, amavuta, ivyokurya, imiti, n’ibindi Ubushuhe bwo gukora bw’ivyo bikoresho buri hagati ya -196~800°C.
Ico kibanza co gushiramwo umupfunda wo gupima umuvuduko w’amazi (swing check valve) ntigifise aho kigarukira, akenshi gishirwa ku muyoboro uringaniye, ariko kandi gishobora gushirwa ku muyoboro uhagaze canke umuyoboro uhagaze.
Igihe gikoreshwa c’umuvuduko w’ibinyugunyugu ni umuvuduko muto n’umurongo munini, kandi igihe co gushiramwo ni gito. Kuko umuvuduko w’ibikorwa vy’umuvuduko wo gupima ikinyugunyugu udashobora kuba munini cane, ariko umurongo w’izina ushobora kuba munini cane, ushobora gushika ku 2000mm irenga, ariko umuvuduko w’izina uri munsi ya 6.4MPa. Igikoresho co gupima ikinyugunyugu gishobora gukorwa mu bwoko bw’ibipande, ivyo muri rusangi bishirwa hagati y’ibipande bibiri vy’umuyoboro mu buryo bw’uguhuza ibipande.
Ico kibanza co gushiramwo umupfunda wo gupima ikinyugunyugu ntigifise aho kigarukira, gishobora gushirwa ku muyoboro uringaniye, umuyoboro uhagaze canke umuyoboro uhagaze.
Igikoresho co gupima amazi (diaphragme check valve) kibereye imiyoboro ishobora guterwa n’inyondo y’amazi. Ico gikoresho gishobora gukuraho neza inyundo y’amazi iterwa n’ugusubira inyuma kw’ivyo bikoresho. Kubera ko ubushuhe bwo gukora n’inguvu zo gukora z’ibikoresho vyo gupima amazi bifise aho bigarukira kubera ibikoresho vy’amazi, muri rusangi bikoreshwa mu mirongo y’amazi y’umuvuduko muto n’ubushuhe busanzwe, cane cane ku mirongo y’amazi yo mu ruzi. Muri rusangi, ubushuhe bwo gukora bw’ivyo bikoresho buri hagati ya -20~120°C, kandi umuvuduko wo gukora uri munsi ya 1.6MPa, ariko umuvuduko wo gusuzuma diaphragm ushobora gushika ku murongo munini, kandi DN nkuru ishobora kuba irenga 2000mm.
Diaphragm check valve yarakoreshejwe cane mu myaka iheze kubera ubushobozi bwayo bwiza cane bwo gukingira amazi, ubuhinga bworoshe cane n’igiciro gito co gukora.
Igikoresho co gupima umupira gifise ubushobozi bwo gukingira neza, gikora neza kandi gishobora guhangana n’inyondo y’amazi kuko igikingira ni umubumbe upfutse n’imipira; kandi kubera ko ikidodo gishobora kuba umupira umwe canke imipira myinshi, gishobora guhindurwa umurongo munini . Ariko rero, ikidodo caco ni umubumbe w’umwobo upfutse n’imipira, udashobora gukoreshwa mu miyoboro y’umuvuduko munini, ahubwo ubereye gusa mu miyoboro y’umuvuduko uri hagati n’uw’umuvuduko muto.
Kubera ko ibikoresho vy’igipfukisho c’umupira wo gupima bishobora gukorwa mu cuma kitagira ibara, kandi umubumbe w’ikidodo ushobora gupfukwa n’ipulasitike y’ubuhinga ya PTFE, birashobora kandi gukoreshwa mu mirongo y’amazi ifise ibikoresho rusangi bishobora gusenyura.
Ubushuhe bukora bw’ubwo bwoko bw’ivyuma bigenzura buri hagati ya -101~150°C, umuvuduko w’izina ni ≤4.0MPa, kandi umurongo w’izina uri hagati ya 200~1200mm.
