Say gagala na pangusar na check valve et pian ag-onbaliktad so agos na medium, tan say check valve et kaslakan ya iiyan ed outlet na pump. Niarum ni, nepeg met ya mangiyan na check valve ed outlet na compressor. Diad antikey, pian naprebentaan so pabaliktad ya agos na medium, nepeg ya mangiyan na check valve ed kagawaan, kagawaan odino tubo.
Kaslakan, saray vertical lift check valve et uusaren ed saray horizontal ya tubo ya say diametro to et 50mm. Say straight-through lift check valve et nayarin i-install ed parehon horizontal tan vertical ya tubo. Say balbula ed leksab et kaslakan ya akapuesto labat ed patayo na tubo na lolooban na bomba, tan say pegley et onaagus manlapud leksab ya anggad tagey.
Say swing check valve et nayarin gawaen ya atagey ya working pressure, say PN et nayarin onabot ed 42MPa, tan say DN et nayarin gawaen met ya baleg, say sankatageyan et nayarin onabot ed masulok ya 2000mm. Base ed nanduruman materyales na shell tan seal, nayarin iyaplika itan ed antokaman ya working medium tan antokaman ya working temperature range. Say medium et danum, singaw, gas, corrosive medium, larak, naakan, tambal, tan arum nira. Say temperatura na medium et walad baetan na -196~800°C.
Say posisyon na pangipuesto ed swing check valve et aliwan limitado, kaslakan ya ipuesto ed pabitay ya tubo, balet nayarin ipuesto met ed pabitay ya tubo odino diad pabitay ya tubo.
Say onaplikan pankanawnawa na butterfly check valve et say abeban presyon tan baleg a diametro, tan say pankanawnawan pangipuesto et limitado. Lapud say working pressure na butterfly check valve et ag nayarin atagey, balet say nominal diameter to et nayarin baleg, ya nayarin onabot ed masulok ya 2000mm, balet say nominal pressure et abeba nen 6.4MPa. Say butterfly check valve et nayarin gawaen ya wafer type, ya kaslakan ya iiyan ed baetan na duaran flange na pipeline ya singa wafer connection.
Say posisyon na pangipuesto na butterfly check valve et aliwan limitado, nayarin ipuesto itan ed horizontal pipeline, vertical pipeline odino inclined pipeline.
Say diaphragm check valve et matukoy parad saray tubo ya mainomay ya na-water hammer. Say diaphragm et sarag ton ekalen so martilyo na danum ya sengegan na baliktaran ya agos na medium. Lapud say temperatura na pantratrabaho tan say presyon na operasyon na saray check valve na diaphragm et limitado ed materyal na diaphragm, kaslakan ya uusaren iratan ed saray tubo ya abeba so presyon to tan normal so temperatura to, lalo la ed saray tubo na danum ed gripo. Diad inkalapagan, say temperatura na medium et walad baetan na -20~120°C, tan say presyon na pantratrabaho et abeba nen 1.6MPa, balet say diaphragm check valve et makagamor na mas baleg a diametro, tan say sankatageyan ya DN et nayarin masulok ya 2000mm.
Say diaphragm check valve et malaknab ya uusaren ed apalabas iran taon lapud ekselentin performance to ya ag-onlooban na danum, medyo simpli so istruktura to tan abeba so gastos ed panaggawa to.
Say ball check valve et walaan na maong ya performance ed panag-seal, napanmatalkan ya operasyon tan maong ya resistensya na water hammer lapud say seal et sakey a globo ya asakbongan na goma; tan lapud say seal et nayarin saksakey a bola odino dakel a bola, nayarin gawaen itan ya baleg so diametro to. Balet, say seal to et sakey a buer ya asakbongan na goma, ya ag matukoy ed saray tubo ya atagey so presyon to, balet matukoy labat ed saray tubo ya abeba so presyon to.
Lapud say shell material na ball check valve et nayarin gawad stainless steel, tan say hollow sphere na seal et nayarin sakbongan na PTFE engineering plastic, nayarin usaren met iya ed saray pipeline ya walay general corrosive media.
Say temperatura na sayan klase na check valve et walad baetan na -101~150°C, say nominal ya presyon et ≤4.0MPa, tan say nominal ya diametro et walad baetan na 200~1200mm.
